The General Plan, which is required by law in the State of California, identifies current and future needs, sets policy, and provides a basis for land use decision-making by policymakers such as the Planning Commission and the City Council. Diamond Bar's current General Plan dates back to 1995 and is in need of an update as new opportunities, challenges, and approaches have emerged in recent years. The General Plan update process provides an exciting opportunity for Diamond Bar community members to share their vision for the city's future and provide input on the city's long-term goals and development opportunities. 1.2 Purpose and Organization of the Existing Conditions Report This Existing Conditions Report represents the first major step in the process of updating the General Plan for the City of Diamond Bar. This report provides spatial information on existing conditions in the city and its surrounding areas as well as an analysis of growth prospects and land demand. The Existing Conditions Report is used as a basis for: • Facilitating community input on planning issues and visions during community workshops; • Preparing alternative land use and transportation planning scenarios; • Formulating policies and implementation actions for the General Plan; and • Creating the environmental setting portion of the Environmental Impact Report for the General Plan. The focus is on resources, trends, and critical concerns to frame decision-making for the long-term physical development of the city. Much of the information, including that on land uses, natural resources, civic and transportation infrastructure, current development projects and potential development capacity, is presented with maps. The Existing Conditions Report is organized into three separate volumes. • Volume L Land Use, Community Character, and Design; and Mobility and Circulation 1.1 Packet Pg. 10 1.1 Diamond Bar General Plan Update • Volume H. Economic Review and Market Assessment Volume III. Environmental Constraints and Opportunities; and Public Facilities, Services, and Utilities VOLUME I: LAND USE, COMMUNITY CHARACTER, AND DESIGN; AND MOBILITY AND CIRCULATION This is the first of three volumes of the Existing Conditions Report. An overview of the organization and contents of Volume I is provided below. 1. Introduction and Overview. This chapter provides an overview of the General Plan update, the purpose and organization of the Existing Conditions Report, and the project and its setting. It also distills the baseline research and analysis of Volume I of the Existing Conditions Report into planning considerations that should be addressed as the General Plan update process moves forward. 2. Land Use, Community Character, and Design. This chapter describes the existing use of land in the General Plan Planning Area, current General Plan land use designations, zoning, and relevant plans and land use policies. It also details the community's urban form and identity, including a close look at key sites that provide opportunities for developing into gathering places that can build the community's sense of identity. 3. Circulation. This chapter provides an overview of the physical and operational conditions of the circulation network in Diamond Bar, including roadways, pedestrian and bicycle circulation, public transit, and goods movement. 1.3 Regional Setting The City of Diamond Bar is located at the far eastern edge of the San Gabriel Valley, within 30 miles driving distance of the cities of Los Angeles, Riverside, and Irvine. The western edge of the city lies at the intersection of State Routes 57 (SR -57) and 60 (SR -60), with SR -57 connecting to Interstate 10 1.5 miles to the north and SR -60 connecting to State Route 71 (SR -71) 1.75 miles to the east. The Industry Metrolink Station lies on Diamond Bar's northern border with the City of Industry. The regional setting is depicted in Figure 1-1. 1.4 Planning Area The General Plan Planning Area (Planning Area), shown in Figure 1-2, is defined as the land area addressed by the General Plan update. The Planning Area encompasses 13,039 acres, of which 73 percent is in the city limits and the remaining 27 percent is in the Sphere of Influence (SOI). It is bounded by the Cities of Industry and Walnut to the north, Pomona and Chino Hills to the east, Brea to the south, and unincorporated Los Angeles county to the west. While Diamond Bar does not have jurisdiction in areas outside of its city limits, general plans commonly consider land outside a city's jurisdictional boundaries that "bears relation to its planning" (California Government Code Section 65300). This typically includes a city's SOI, and may also include additional land.

The city includes mostly low-density residential development, in addition to commercial, office, and industrial development and public facilities, including parks and schools (see Section 2.1). SPHERE OF INFLUENCE The Sphere of Influence (SOI) is defined as the ultimate physical boundary and service area of the city, and it encompasses both incorporated and unincorporated territory that is envisioned to be the city's ultimate service area. The Los Angeles County Local Agency Formation Commission (LAFCO) reviews and approves proposed boundary changes and annexations affecting the SOI. The SOI, which has remained relatively constant since it was first approved in 1990, includes part of Tonner Canyon, an undeveloped wooded canyon that stretches in a crescent shape from SR -57 northwest to SR -60. Beyond land within city limits, the city's SOI boundary includes an additional 3,513 acres (5.5 square miles) outside of the city limits, which accounts for 27 percent of the total land in the Planning Area. Table 1-1 summarizes the composition of the Planning Area, including the amount of land in the City of Diamond Bar, the SOI, and unincorporated Los Angeles County outside the SOI. Figure 1- 2 shows the Planning Area, including the Diamond Bar city limits and Diamond Bar SOI boundaries.

The most significant findings from topics covered in Volume I are summarized below. • Diamond Bar lacks a traditional downtown, though there are multiple opportunity areas with potential to establish concentrated center(s) of activity that may also help further define the community's identity. A typical downtown is a center of civic life, features buildings and streets designed to the human scale, features a mix of land uses, and prioritizes many modes of transportation equally. Diamond Bar's major commercial centers, on the other hand, prioritize automobile usage, are flanked by large parking lots, often feature large windowless facades, are comprised of only commercial uses, and lack pedestrian -oriented street life. There are some elements of placemaking in Diamond Bar, including ranch and post design features that invoke the city's agricultural origins, the City Windmill, and signs welcoming visitors to Diamond Bar. However, many shopping centers and places of public activity lack design elements distinct to the city. • Should the Diamond Bar community decide that "placemaking" or establishment of a town center is a high priority, multiple opportunity areas exist with potential to establish concentrated center(s) of activity that could help achieve this goal. There are several activity nodes in the city that are underutilized and thus good candidates for redevelopment and intensification necessary to create a true activity center. These areas include the golf course, Oak Tree Plaza/Ranch Center, the corridor along Diamond Bar Boulevard between Golden Springs Drive and SR -60, and the geographically central intersection of Grand Avenue and Diamond Bar Boulevard. • Regional traffic and congestion is a significant problem that needs to be addressed, though the City's ability to influence and control regional traffic is limited. Two highways (SR -57 and SR -60) run through the city and along its westerly and northerly boundaries. These heavily -congested highways are accessed by several on- and off -ramps throughout Diamond Bar. Several of these ramp intersections experience high levels of delay during one or both peak hours. In addition, high travel volumes along these highways can lead to traffic cutting through the city (on roads such as Diamond Bar Boulevard) to avoid congestion. The City should be cognizant of this issue and examine opportunities to avoid delay, spillover, or cut -through traffic onto Diamond Bar's roadways. The City has begun implementing adaptive traffic control systems along major corridors, which would help address issues such as spillover. • Addressing gaps in the bicycle network may alleviate congestion. Examples of roadways with discontinuous bikeways include Golden Springs Drive, where the bicycle lanes terminate several times. Also, the bicycle lanes on Grand Avenue to Chino Hills terminate at the city limits, despite available right-of-way along Grand Avenue through the city; however, street grade and other safety concerns could create barriers to 6 Packet Pg. 15 1.1 Existing Conditions Report — Volume 1, February 2017 Land Use, Community Character, and Design and Mobility and Circulation implementing bikeways along this road and should be assessed. Nonetheless, opportunities exist to fill in gaps and expand the bikeway network. This can help in reducing the city's single -occupant vehicle mode share. • Traffic calming strategies can improve safety on Diamond Bar's streets. Steep grades on some roadways in the city can lead to high vehicle speeds. Traffic calming is a potential method to discourage high vehicle speeds and improve safety, which the City has already implemented on local neighborhood streets through its Neighborhood Traffic Management Program. Traffic calming can also discourage regional cut -through traffic from SR -57 and SR -60 through the city, reducing congestion. • The predominant mode of travel in Diamond Bar is the automobile. The vast majority of commuters drive, especially with single -occupant vehicles. The single - occupant mode share for Diamond Bar is higher than the average for Los Angeles County and the state. Public transit, walking, and bicycling mode shares are less than half of the mode share in the rest of the county. In addition, carpooling is somewhat lower in Diamond Bar, even though the City provides two park-and-ride lots. Reasons for this high level of vehicular travel include the city's land use pattern, which is primarily residential and requires residents to travel elsewhere for work. The steep grade on some major roadways can also discourage residents from walking or bicycling to work. Future transportation projects will impact both highways and local roads in Diamond Bar. The SR-57/SR-60 Confluence Project at Grand Avenue and the SR-60/Lemon Avenue interchange will impact traffic operations on the highways as well as Diamond Bar roadways. For example, construction delays can cause vehicle queues at on -ramps to spill over onto city streets. In addition, drivers seeking to bypass construction could cut through Diamond Bar. The City should continue to monitor and be aware of impacts to local roadways, and coordinate with Caltrans to reduce negative impacts on local streets due to these and other future transportation projects. Packet Pg. 16 Diamond Bar General Plan Update This page intentionally left blank. 1.1 Packet Pg. 17 1.1 2 Land Use and Urban Form 2.1 Existing Use of Land Existing use of land refers to how land is currently being utilized; it does not refer to the General Plan land use designations or zoning districts. In other words, what is built on the ground may differ from what is allowed under current regulations. Analysis of the existing land use pattern in the Planning Area helps provide insight into both historical patterns of development and opportunities for future development. Table 2-1 shows the types of existing use of land in the Planning Area, including within the City of Diamond Bar and County unincorporated areas, and Figure 2-1 illustrates the proportion of each type of existing use of land in the Planning Area, excluding rights-of-way. Figure 2-2 shows the overall pattern of existing use of land in the Planning Area. Residential uses account for half of all land within the city and 37 percent of land in the Planning Area. The vast majority of residential uses (89 percent) are single-family detached homes. Vacant land makes up 18 percent of all land within the city limits and 16 percent of land in the Planning Area overall, which includes areas within the city that are naturally undeveloped due to environmental constraints, but which are not formally developed or maintained as parkland. Parks and open spaces account for another eight percent of land in the city, and over 30 percent of land in the Planning Area due to the predominance of open space in the SOI. Public and community facilities make up four percent of land in the city and three percent of the Planning Area, which are very similar proportions to those for commercial and mixed uses. Industrial uses account for less than one percent of land in the city and the Planning Area. Streets and other transportation rights- of-way constitute the remaining 16 percent of land within the city limits.

Many of the single-family and multi -family residential uses in the city are part of gated communities, including The Country, an exclusive gated community of over 800 large -lot, detached single-family homes in the southeastern hills. Multi -family residential uses exist in clusters by the golf course, along Golden Springs Drive by the city's northern border, and along Diamond Bar Boulevard. Commercial uses are found in several pockets along SR -60 and SR -57, as well as the intersection of Grand Avenue and Diamond Bar Boulevard. Offices uses are concentrated in the Gateway Corporate Center complex south of Golden Springs Drive and SR -57, with smaller concentrations at opposite ends of SR -57 and along Grand Avenue. The sole cluster of industrial and warehousing uses lies by the Metrolink station along the border with the City of Industry. Public parks and recreational facilities are found mostly in the eastern half of the city, bordering residential uses. Vacant areas and open spaces are prevalent in the Planning Area's many steep hillsides, including the Tres Hermanos area to the northeast by Chino Hills Parkway, as well as the entirety of the SOI to the south of the city limits. II Packet Pg. 20 1.1 Diamond Bar General Plan Update 2.2 Existing General Plan Land Use Designations Figure 2-3 shows the 1995 General Plan's intended uses of land in the Planning Area through the location of land use designations, which are further described in Table 2-2. Density and intensity standards regulate how much development is permitted on a site and are used to evaluate development during the site planning review process. Currently, the General Plan and Zoning Ordinance include density standards for residential uses based on minimum lot size and the net site area required per unit. For non-residential uses, development intensity is regulated in the General Plan by minimum lot size as well as a measure known as Floor Area Ratio (FAR), which refers to the ratio between a building's total floor area and the total area of the site. For instance, a one-story building occupying a quarter of a parcel has an FAR of 0.25, while a two-story building occupying the same quarter of a parcel has an FAR of 0.5. The 1995 Land Use Diagram aligns very closely with the current land use pattern. Low Density Residential land use designations are the most prominent and are located throughout the city. One multifamily development to the north and east of the Grand Avenue and Diamond Bar Boulevard intersection has been built despite a Low Density Residential land use designation. Rural Residential land uses are concentrated in the area east of Diamond Bar Boulevard and south of Grand Avenue, though the area closest to that intersection is home to Low -Medium Residential land uses. Low -Medium Residential land uses are also found north and west of both intersections of SR -57 and SR -60, and in the area bounded by SR -57 to the west, Pathfinder Road to the north, and Diamond Bar Boulevard to the east. Commercial uses are most prevalent at the city's edges, notably where SR -57 intersects SR -60 as well as Diamond Bar Boulevard, as well as the central intersection of Diamond Bar Boulevard and Grand Avenue. The city's one pocket of industrial uses lies in the northwest along the Metrolink tracks just above SR -60. The 1995 General Plan designated four Planning Areas, and since the adoption of the General Plan, a fifth Planning Area was added. These areas total over 1,200 acres and were designated for master - planning purposes. Planning Area 1 (PA -1) consists of 720 acres west of Chino Hills Parkway that contains a portion of the Tres Hermanos Ranch, which stretches east into Chino Hills. The area is overseen by the Tres Hermanos Conservation Authority, a Joint Powers Authority formed by the cities of Diamond Bar and Chino Hills with the City of Industry in order to guide development in a manner beneficial to all three cities. Multiple uses have been considered for this area over the years, from the development of affordable housing to a sale to the City of Industry in order to build a reservoir and hydro -electric power plant and solar farm. • Planning Area 2 (PA -2) consists of 424 acres of steeply -sloped, vacant natural areas in two non-contiguous areas. The larger area lies north and east of the intersection of Grand Avenue and Diamond Bar Boulevard, while the other area lies between Pantera Park to the west and PA -1 to the east. No development has yet occurred in PA -2. • Planning Area 3 (PA -3) consists of 55 acres south of the intersection of Grand Avenue and Golden Springs Drive, which was developed under the Diamond Bar Village Specific Plan as discussed in Section 2.4 in this chapter. 12 Packet Pg. 21 1.1 Existing Conditions Report — Volume 1, February 2017 Land Use, Community Character, and Design and Mobility and Circulation Planning Area 4 (PA -4) consists of 87 acres south of South Pointe Middle School. The City Council adopted the South Pointe West Specific Plan and tentative tract map in 2007, approving a 99 -unit detached residential condominium subdivision and a 6.8 -acre neighborhood park (Larkstone Park). The subdivision and park are currently under construction. • Planning Area 5 (PA-5/RH-30) consists of 32 acres directly south of Diamond Bar Ranch High, and is entirely surrounded by PA -1. While not included in the 1995 General Plan, PA -5 was established under a General Plan Amendment and Zone Change to implement the Fourth and Fifth Cycle Housing Elements, and was designated RH-30 to accommodate 490 high-density, multi -family housing units. 13 Packet Pg. 22 1.1 Diamond Bar General Plan Update This page intentionally left blank. 14 Packet Pg. 23 Figure 2-2: Existing Land Use LOS ANGELES COUNTY Metrolink Station T GST lolnur ES �i $path Palnte� M5.

A proposed slope density ordinance applied to all land use designations in the city would reduce the number of dwelling units otherwise designated for the property as a function of average slope of the land in excess of 25 percent. Source: 1995 Diamond Bar General Plan. 2.3 Current Zoning & Land Use Regulations Zoning is used to achieve the goals of the General Plan and to encourage compatible uses of proximate sites or parcels. Zoning ordinances consist of a zoning map defining the location of districts and a code detailing requirements for each district. Diamond Bar's zoning ordinance only applies within the city limits, whereas the SOI is subject to Los Angeles County zoning. Figure 2-4 displays the existing zoning for the Planning Area, including Los Angeles County zoning districts for unincorporated land. Table 2-3 summarizes existing zoning regulations guiding scale and placement of development, including density, lot area, front setback, and height requirements for each of the city's zoning districts. The density column categorizes density by dwelling units per acre for residential development, and floor area ratio (FAR) for non-residential development. LOW DENSITY RESIDENTIAL Rural Residential (RR), Low Density Residential (RL), and Low/Medium Density Residential (RLM) zoning districts allow for the development of single-family homes. The Rural Residential zoning district applies to The Country Estates of Diamond Bar. The majority of residential land in Diamond Bar is zoned for low density residential use. 18 Packet Pg. 27 1.1 Existing Conditions Report - Volume 1, February 2017 Land Use, Community Character, and Design and Mobility and Circulation -W14•7lIl-WC:IEel :IDI4Z ]hWd:I*I1•».kdr_lI Medium to high density zoning classifications include Medium Density Residential (RM), Medium/High Density Residential (RMH), High Density Residential (RH), and High Density Residential -30 units/acre (RH-30). They allow all or some of the following types of residential development: townhomes, condominiums, apartments, mobile homes, and other multifamily projects. Areas zoned for higher density residential are scattered throughout the city, though they tend to be located along major arterials. Land zoned for medium to high density residential development occupies far less land area than low density residential districts. OFFICE Diamond Bar has three office land use designations; Office, Professional (OP); Office, Business Park (OB); and Commercial Office (CO). Office, Professional (OP) districts are located near the intersection of SR -57 and Brea Canyon Road, near the intersection of Grand Avenue and Golden Springs Drive, near the Industry Metrolink Station, and along Diamond Bar Boulevard north of the intersection of SR -60. The Gateway Corporate Center along Golden Springs Drive is the only area of Diamond Bar to be zoned Office, Business Park (OB). Most land zoned Commercial Office (CO) is located along the SR -57 corridor, though one Commercial Office site is located near the intersection of Grand Avenue and Diamond Bar Boulevard, and another is located near the intersection of Grand Avenue and Golden Springs Drive. COMMERCIAL Areas zoned for general commercial use include Neighborhood Commercial (C-1), Community Commercial (C-2), and Regional Commercial (C-3). Centers of retail and services are typically zoned commercial. These districts are primarily located along major arterials. INDUSTRIAL Light Industrial (I) consists of light industrial and manufacturing land uses, including research and development, office -based industrial uses, business support services, and commercial areas requiring larger sites than are available in the commercial zoning districts. Diamond Bar's Light Industrial zoning districts are located close to the Industry Metrolink Station. AGRICULTURAL/OPEN SPACE/RECREATION The Tres Hermanos site comprises all of the land zoned as Agriculture (AG) in Diamond Bar. The Open Space/Conservation (OS) zoning district is specified for areas of the city with open space resources, including scenic qualities, sensitive environmental features including wildlife habitat, and/or natural hazards. The Diamond Bar Golf Course is zoned as Open Space/Conservation, as are parks including Sycamore Canyon Park and Carlton J. Peterson Park. The Recreation (REQ zoning district applies to areas appropriate for active and passive recreational uses, including golf courses, public parks, and private recreational facilities. The Little League Fields are zoned as Recreation. Heights and Setbacks Height limits are low (35 feet, or about three stories) in most of the city. Buildings in areas zoned for "Office, Business" use are allowed the greatest heights—a maximum of six to eight stories. These 19 Packet Pg. 28 Diamond Bar General Plan Update taller structures tend to be located in single -use office parks, and are thus separated from residential and other land uses. Building frontages are set back far from the street (10-30 feet), meaning that structures tend to be separated from the street via lawn, sidewalk, landscaping element, or parking.

Source: Diamond Bar City Code 1.1 23 Packet Pg. 32 1.1 Diamond Bar General Plan Update 2.4 Previous Plans and Proposals DIAMOND BAR VILLAGE SPECIFIC PLAN The Diamond Bar Village Specific Plan was adopted in May 2004, and 180 dwelling units were built out by 2016 according to the specifications below. The 70.5 -acre site covered by the Specific Plan is located south of the Golden Springs Drive and Grand Avenue intersection. The Specific Plan proposed the development of up to 200 high-density residential units, as well as up to 270,100 square feet of new commercial, retail, and institutional uses with a maximum FAR of 1.0. The Specific Plan stipulated new development on the site should meet the following goals: include a mix of uses, achieve citywide development goals described in the General Plan; feature landscaping and architectural elements cohesive with the identity of the community; and enhance the character and style of the region. In 2004, the site was mostly undeveloped with the exception of the Calvary Chapel. The site was divided into four Sub -Planning Areas in the Specific Plan, described below: • Sub -Planning Area 1 was intended as the site of a 170,000 -square -foot major retail tenant. A 130,000 -square -foot Target store has since been built on the site. Smaller retail facilities with footprints under 10,000 feet front Golden Springs Drive. • Sub -Planning Area 2 planned for the addition of up to 200 attached housing units. The gated residential development off Vantage Drive was built in accordance with the Specific Plan. • Sub -Planning Area 3 is part of the Vantage Drive neighborhood. • Sub -Planning Area 4, which includes the hills to the west of the residential development in Sub -Planning Area 2, is designated as open space. SOUTH POINTE WEST SPECIFIC PLAN The South Pointe West Specific Plan and tentative tract map were adopted in 2007, approving a mix of residential, park, and open space land uses on a 34.5 -acre property. The plan allows for a 99 - unit detached residential condominium subdivision as well as Larkstone Park, a 6.8 -acre neighborhood park off Larkstone Drive. The subdivision and park are currently under construction. SITE D SPECIFIC PLAN The Site D Specific Plan, adopted in 2012, pertains to an approximately 30 -acre site in the southwestern portion of the city that has since been developed. The site is located on the southeast corner of Brea Canyon Road and Diamond Bar Boulevard. Prior to development, the empty site was jointly owned by the Walnut Valley Unified School District and the City of Diamond Bar. The Specific Plan guides development of "Willow Heights," a master planned subdivision combining residential, open space, and recreational land uses. The Willow Heights gated community, which was completed in 2016 by Lennar Corporation, consists of 47 single family homes, 73 detached condominium units, and 62 multifamily condominium units within three distinct communities - 182 residential units in total. As required under the Specific Plan and subsequent tract map, Lennar 24 Packet Pg. 33 1.1 Existing Conditions Report – Volume 1, February 2017 Land Use, Community Character, and Design and Mobility and Circulation also constructed a 4.3 -acre public park at the intersection of Brea Canyon Road and Diamond Bar Boulevard. The park opened to the public on December 3, 2016. AERA ENERGY PROPOSAL While not within the Planning Area, a 2,935 -acre site in the Puente Hills owned by Aera Energy has been the subject of annexation discussions, and would represent a major addition to the City if annexation were to occur. The site, used primarily for oil production and cattle grazing, is almost entirely in unincorporated Los Angeles County, and is surrounded by the cities of Brea, La Habra, La Habra Heights, Industry, Diamond Bar, and unincorporated Rowland Heights. Aera Energy sought to develop the site into a master planned residential community, and in 2007 the City of Diamond Bar began preparing an Environmental Impact Report (EIR) for the project. The phased development was slated to contain a maximum of 3,600 residential units and 300,000 square feet of commercial uses. More than half of the site would be devoted to internal greenbelts and open space. The site is not within the General Plan's Planning Area, but if the site were to be developed according to the proposal, about 2,000 acres of the new development would be annexed to the City of Diamond Bar. The proposal faced opposition from environmental advocates, due in part to the fact that the site is a wildlife corridor. Officials from the City of Diamond Bar were also highly critical of many aspects of the proposal. On May 7. 2008, after months of impasse, the City Manager informed Aera executives that he had directed staff to suspend further work on the project. As of 2016, Aera Energy still owns the site, it is still unincorporated, and it has not been developed. 2.5 City Form and Design This section provides an overview of Diamond Bar's physical form and basic development pattern—its urban design characteristics. Urban design is the physical embodiment of community character, and plays a significant role in city identity. Elements of good urban design, including streetscapes, scale, public art and signage, and accessibility, can determine the extent to which a city is recognizable and feels like a unique destination. This section examines urban design in Diamond Bar at a range of scales, from neighborhood to citywide. EVOLUTION OF CITY FORM Historical Development The area now known as the City of Diamond Bar began as a ranch in 1840, but the community rapidly developed into a residential haven in the latter half of the twentieth century. This section outlines this history of development, and how these development pressures impacted city streetscapes and urban form. Refer to Figure 2-5 for maps depicting the development of streets in the city over time. Pre -1954. Urban development in Diamond Bar remained sparse until the late 1950s. By 1954, a few streets platted in a spread -out grid pattern had emerged next to the Union Pacific Railroad on the west side of the city, where land is relatively flat. Many of the current land uses in this area complement the railroad, such as warehousing and manufacturing. The hilly eastern portion of the city remained relatively untouched by development prior to 1954, with the notable exception of a few regional arterials traversing the hillsides. 25 Packet Pg. 34 1.1 Diamond Bar General Plan Update • 1954-1966. In 1956, the Christiana Oil Corporation and the Capital Oil Company, a subsidiary of the Transamerica Corporation, purchased the Diamond Bar Ranch. The new owners drafted a comprehensive development plan for the city, making it one of the first master -planned communities in the County. The first model homes were built at the north end of the town in 1960, ushering a development boom. New subdivisions emerged between Pathfinder Road, Diamond Bar Boulevard, and Brea Canyon Road; near the intersection of 5' Avenue and Old Brea Canyon Road; and near the intersection of Brea Canyon Road and Diamond Bar Boulevard. Lot sizes in these subdivisions range in scale from about 7,500 to 9,000 square feet. Though many of the collector and neighborhood roads in these subdivisions are curvilinear, development is still relatively compact in these neighborhoods. • 1966-1981. In the 1960s, suburbanization outward from the Los Angeles basin created regional pressure to develop single-family homes in residential neighborhoods and create a comprehensive regional transportation network. During this era, SR -60 and SR -57 were constructed near the western border of the city. Additional subdivisions were built in the eastern portion of Diamond Bar on hilltops. Platted streets of new subdivisions were generally curvier and more spread out than streets in earlier subdivision developments, due in part to development in hillier terrain in the eastern part of the city. Lot sizes tend to be around the same size or larger than lots in developments planned from 1954-1966, and they typically range in size from 10,000 to almost 20,000 square feet. As such, many of these neighborhoods today are zoned for low or rural residential use. • 1981 -Present. Diamond Bar today is primarily a residential community. Though the population of Diamond Bar continues to grow, the pace of growth is markedly slower than it was from 1966-1981. Single-family homes constructed from 1981 onward most typically have two stories, larger than the ranch -style built during most previous stages of growth. The southeastern hills area in particular underwent greater development, and in this area lot sizes are typically an acre or larger. Today, the city is mostly built out, though some undeveloped spaces still exist on the periphery and in vacant lots. Current Form Diamond Bar's commercial and residential development is perched upon a landscape of rolling hills and valleys. Similar to other bedroom communities in the area, most residential streets in Diamond Bar are curvilinear. Street patterns in Diamond Bar are predominantly determined by topography, with streets conforming to the contours of the terrain. In particularly steep areas such as in The Country Estates, development is concentrated only on the peaks of the hills and along ridgelines. Street patterns in flatter residential areas, such as the Diamond Bar Hills subdivision, also conform to the slope of the terrain, but streets and a larger number of homes are clustered together owing to the relative flatness of the topography. More detail on existing land use is found in Section 2.2. There is a semblance of disconnect between differing land uses and adjacent neighborhoods. Many residential areas are gated off from major arterials, creating insular communities of exclusivity. In some cases, residential streets in adjacent subdivisions are aligned, but form dead ends rather than join together into one street. Due to the distinctive street patterns of individual neighborhoods, similarity of housing typologies, and the lack of connections to other neighborhoods, the neighborhood unit contributes significantly to the identification and feeling of place in Diamond Bar. 26 Packet Pg. 35 PPO PUU�J \, I \ LA PUENTE PUAD I I 1 1 1 I / / L I / — AI I , ----' 2015 1.1 Figure 2-5: Historical D evelopm en Freeway Paved Road ----------- Unpaved Road Railroad Electrical Transmission Line -------- 2016 City Limits Elevation in feet 500 600 700 800 900 1,000 L 1,100 L 1,200 1,300 1,400 (T) 0 1/4 1/2 1 2 3 MILES Source: USGS 7.5 minute quads:Yorba Linda, 1950,1964,1981; San Dimas 1954,1966,1981; City of Diamond Bar, 2016. o— LP PUENTE I \\ e— 1 1 1 T PEP1 e - _._ _ _ _ _._ _ _ -- _ / STN AJENUE — / / I I / I / _ 1 , , I J / '''-------=- ----' 1954 PPO PUU�J \, I \ LA PUENTE PUAD I I 1 1 1 I / / L I / — AI I , ----' 2015 1.1 Figure 2-5: Historical D evelopm en Freeway Paved Road ----------- Unpaved Road Railroad Electrical Transmission Line -------- 2016 City Limits Elevation in feet 500 600 700 800 900 1,000 L 1,100 L 1,200 1,300 1,400 (T) 0 1/4 1/2 1 2 3 MILES Source: USGS 7.5 minute quads:Yorba Linda, 1950,1964,1981; San Dimas 1954,1966,1981; City of Diamond Bar, 2016. 1.1 Existing Conditions Report – Volume 1, February 2017 Land Use, Community Character, and Design and Mobility and Circulation As Diamond Bar is primarily residential, commercial uses are limited to small clusters and are concentrated around intersections of greater street hierarchy. Land uses tend to be separated, and are easiest to access via automobile. Shopping centers and office parks are suburban in character, meaning buildings tend to be set far back from the street, are primarily auto -oriented, and consist of almost exclusively commercial land uses. Commercial facilities are predominantly located on four- to six -lane arterial streets, spanning about 100 feet across. Storefronts generally face towards inner parking lots rather than the street. Pedestrians must walk long distances across parking lots and sometimes major thoroughfares to reach their shopping destinations. Heights in commercial areas are limited to 35 feet, though most retail facilities are about one story tall. Owing to these characteristics—a dispersed system of shopping clusters oriented towards customers arriving via automobile—Diamond Bar lacks a traditional "downtown." City placemaking and iconography tell the story of Diamond Bar's origins as a ranch. The Windmill, the oldest community landmark, is situated in front of the Diamond Bar Towne Center. Recent streetscape improvements near the intersection of Diamond Bar Boulevard and Grand Avenue—including native landscaping, diamond -patterned pedestrian crossings, and decorative ranch -style rail and post features—provide visual reminders of the city's early history. The city border with Chino Hills near the intersection of Longview Drive and Grand Avenue is marked with a grand entry sign welcoming visitors to Diamond Bar. A city entry landmark, featuring cattle sculptures and a stylized recreation of the original Diamond Bar Ranch gateway, is located at Diamond Canyon Park, near the intersection of Diamond Bar Boulevard and Brea Canyon Road. These features are part of a unified streetscape design theme intended to be established throughout Diamond Bar. Other city entry points are currently marked with older monumentation features which will be replaced over time with structures that follow the current streetscape theme and palette. Streetscapes and the Public Realm Streets are the roots from which community life forms. Pleasant streetscapes—which include site- specific building frontages, sidewalks, street furniture, and landscaping—create safe, attractive, and active streets. Understanding the types of streets in Diamond Bar, their character, and where they are located can give greater understanding to the scale and form of the built environment. This section describes streets as they relate to the physical design and experience of the city; detail on circulation system function is found in Chapter 3. Street Typology • Freeways. Freeways are high speed, high capacity, limited access roadways serving regional traffic. SR -57 and SR -60 cross paths on the northwestern border of Diamond Bar. The freeways are frequently obscured from view from those in Diamond Bar via landscaping, walls, and elevation differentials. Land uses alongside the freeways include commercial, residential, and recreational uses. Most visitors to Diamond Bar arrive via the freeways, and enter the city on Diamond Bar Boulevard, Pathfinder Road, Grand Avenue, Sunset Crossing Road, or Golden Springs Drive. Signage welcoming visitors from the freeways to Diamond Bar is limited. 29 Packet Pg. 38 1.1 Diamond Bar General Plan Update Arterials. Arterials provide circulation between major activity centers and residential areas, and provide access to freeways. Arterials are usually four to six lanes wide. They often feature landscaped medians, sidewalks, and street trees. Arterials are oriented towards automobile usage above all other means of transportation. Though the sidewalk network along the arterials is comprehensive, the pedestrian experience is diminished at times by fences blocking views of buildings from the sidewalk, a lack of benches at bus stops, and long intersection crossings without median refuges. Primarily residential and commercial land uses abut arterials, and most commercial activity in Diamond Bar is located on the major arterials. Storefronts are typically set far back from the arterials. Arterials rarely allow street parking. Major and secondary arterials in Diamond Bar include Pathfinder Road, Diamond Bar Boulevard, Grand Avenue, South Brea Canyon Road, Lemon Avenue (north of Golden Springs Drive), and Golden Springs Drive. • Collectors. Collectors accumulate traffic from residential and commercial areas and channel them to the arterials. They are fronted typically by residential and commercial land uses, and usually have two lanes. In residential areas, they often form the spine of the neighborhood from which neighborhood streets branch out. Collectors often have stoplights where they intersect with arterials and stop signs where they intersect with neighborhood streets. Lycoming Street, Lemon Avenue (south of Golden Springs Drive), and Sunset Crossing Road are examples of collectors. Neighborhood Streets. Neighborhood streets are the narrowest type of street in Diamond Bar. They are typically lined with housing, lawns, and sidewalks, though The Country Estates subdivision does not have sidewalks. They generally encourage the slowest traffic in Diamond Bar via calming measures including low speed limits, speed bumps, and stop signs. Neighborhood streets often allow street parking for residents via permit. They are typically curvilinear and follow the city's hilly topography, and are lined with street trees. Neighborhood streets often result in dead -ends or cul-de-sacs, and intersections with other neighborhood streets are met with stop signs. Right-of-way width for neighborhood streets is about 60 feet, and residences are set at least 20 feet back from the front lot line, making these streets much smaller in scale than the other street types. 30 Packet Pg. 39 Existing Conditions Report — Volume 1, February 2017 Land Use, Community Character, and Design and Mobility and Circulation Streetscapes Freeway.

As the General Plan update process progresses, whether the community wants to try to foster such a place, and if so, what form it should take, will be critical questions to explore. The purpose of this section is to assess where the greatest potential exists for a town center in Diamond Bar by analyzing the existing urban design conditions of eight major commercial areas. The eight areas are a mix of existing nodes of commercial activity as well as potential opportunity sites for new development or redevelopment. Nodes Diamond Bar has several nodes of concentrated activity. Nodes are areas that serve as magnets for the community, and are activated by pedestrian and/or auto -oriented uses. Some of these areas enjoy relatively consistent activity at all hours, such as the shopping centers, while others experience most of their use during weekdays only, such as the Gateway Corporate Center. These centers of activity currently include educational, office, and retail uses: • Diamond Ranch High School • Diamond Bar High School • Gateway Corporate Center • Diamond Hills Plaza • Oak Tree Plaza/Ranch Center • Diamond Bar Golf Course and adjacent shopping area at intersection of Grand Avenue and Golden Springs Drive • Shopping area at intersection of Grand Avenue and Diamond Bar Boulevard • Shopping area on Diamond Bar Boulevard between SR -60 and Golden Springs Drive • Shopping area at the intersection of Golden Springs Drive and South Brea Canyon Road • Shopping area at intersection of Golden Springs Drive and Lemon Avenue Current Development Projects As of November 2016, there are three development projects in the pipeline with the city. These projects, listed in Table 2-5, account for 54 acres and potentially 247 new condominium units. Not surprisingly, the two projects that contain a non-residential component are located on nodes identified above. 32 Packet Pg. 41 1.1 Existing Conditions Report — Volume 1, February 2017 Land Use, Community Character, and Design and Mobility and Circulation Table 2-5: Diamond Bar Development Pipeline Projects as of November 2016 Project Type Units Acres Status Kmart Site Commercial 8.1 Approved South Pointe & Larkstone Park Single-family 99 36.7 Under construction Oak Tree Plaza/Ranch Center Site Mixed Use 148.0 10.6 Proposed Total 247.0 55.4 Source: City of Diamond Bar, 2016. Opportunity Sites Figure 2-6 identifies current development and opportunity sites within the Planning Area. Opportunity sites are defined as vacant or underutilized areas with potential for land use or development intensity changes. An assessed value (AV) ratio divides the value of existing permanent improvements, or buildings, by the value of the land. An underutilized site is defined for this analysis as a property with an AV ratio below 1.0, whereas a ratio below 0.5 indicates even greater potential. In other words, where the value of the land is worth substantially more than the value of the structure on it, a site may be a candidate for redevelopment. There are 27.6 acres of land in Diamond Bar with an AV ratio below 0.5, and 121.6 acres of land with an AV ratio between 0.5 and 0.99. Building off the opportunity sites analysis, a list of sites with high potential for future development has been refined and provided in Table 2-5.

These commercial areas are places that have potential to serve as "town centers," but owing to their current design are not serving this function. Two of these areas have been selected even though they have development projects in the pipeline, as the timeline and certainty of these projects is unknown. Diamond Bar Golf Course and shopping area at intersection of Grand Avenue and Golden Springs Drive. The County -owned Diamond Bar Golf Course buffers a nearly two-mile segment of adjacent residential and commercial land uses from SR -60. Entrance and exit ramps from SR -60 feed into and out of Grand Avenue, which bifurcates the golf course. The intersection of Grand Avenue and Golden Springs Drive features a variety of uses at the north, east, and south corners, including the golf course clubhouse, restaurants, and retail, including a Target. The Diamond Bar Village Specific Plan sets standards for development of the Target site and surrounding environs on the southeast corner of this intersection. Large surface parking lots comprise most of the street frontage. The Grand Avenue right-of-way is over 120 feet wide, while the Golden Springs Drive right-of-way width is nearly 100 feet. Grand Avenue/Diamond Bar Golf Course (Honda Site). The Honda site is located on the west side of Grand Avenue bordered to the south by SR -57 and SR -60. It is a 4.5 -acre site surrounded on the east, north, and west side by vacant land in the City of Industry. The site was at one time a Honda dealership, but today sits vacant. In March 2016, construction began on a new westbound onramp to SR -57 and SR -60. Oak Tree Plaza/Ranch Center. Retail and professional offices line the east side of Diamond Bar Boulevard between Sunset Crossing Road and Highland Valley Road. Storefronts and offices along Diamond Bar Boulevard are separated from the road by parking lots. Wide sidewalks line Diamond Bar Boulevard. According to the opportunity sites assessment, many of the parcels in this area are underutilized or in the process of being redeveloped. There is a project in the conceptual design phase on this site for a mixed-use development of approximately 148 residential condominium units. The project would entail demolishing the existing structures, with the exception of a 12,000 sq. ft. portion of one Ranch Center building that would be renovated and retained as a commercial use. Shopping area at intersection of Grand Avenue and South Diamond Bar Boulevard. This shopping area, which includes the Diamond Bar Towne Center, spans the four corners of the intersection. The largest anchors are Albertsons and the Walmart Neighborhood Market. Most commercial facilities in this shopping area are retail establishments or restaurants, but there is also a US Post Office, professional offices, a Fire Department, and a church. This shopping area is most easily accessible via foot, automobile, and Foothill Transit Route 286, which makes stops on South Diamond Bar Boulevard. At the intersection, the right-of-way for Grand Avenue is about 100 feet while the right-of-way for Diamond Bar Boulevard is about 120 feet. Commercial establishments are set far back from the streets—the Bank of America on the northeast corner is set back more than 60 feet from Grand Avenue—making these arterials seem even wider than they actually are. Large parking lots flank the front of establishments set farther back from the street. Recent placemaking efforts, including stone paved street crossings, landscaping along pedestrian 37 Packet Pg. 46 1.1 Diamond Bar General Plan Update thoroughfares, and rails featuring windmill iconography in the median of South Diamond Bar Boulevard, imbue the shopping center with a more recognizable character. The Diamond Bar Windmill, the city's oldest historical landmark, is located along the sidewalk on the east side of South Diamond Bar Boulevard. Shopping area on South Diamond Bar Road between SR -60 and Golden Springs Drive. This shopping area was once anchored by the now -vacant 85,000 square -foot Kmart on the west side of South Diamond Bar Boulevard. Most other retail and restaurants in the area are situated in facilities smaller than 10,000 square feet. Across the street from the Kmart site is an approximately 50,000 square -foot building partially occupied by CVS, and a 35,000 square -foot Smart & Final grocery store. Both the Kmart building and grocery store are separated from South Diamond Bar Boulevard by large parking lots. In fact, the right- of-way on South Diamond Bar Boulevard is about 125 feet, but in total the distance between the fagade of the Kmart and the facade of the grocery store is 720 feet, meaning that nearly six streets as wide as South Diamond Bar Boulevard can fit between the two storefronts. The Kmart site and adjoining parking lot can be considered a major opportunity site for redevelopment on account of its combined nearly 6.25 acres of empty space. On October 11, 2016, the Planning Commission approved a plan to demolish the existing Kmart outdoor garden center and subdivide the Kmart building into three retail spaces while adding 12,155 square feet of retail space. The project also includes a new two -tenant, 4,200 square -foot outpad for drive-thru coffee and fast casual dining. Construction is scheduled to commence in January 2017. Diamond Hills Plaza (formerly Country Hills Town Center). This shopping center, like most others in Diamond Bar, is oriented towards automobile usage. Though some shops, such as the Starbucks, are situated adjacent to South Diamond Bar Boulevard, the grade differential between South Diamond Bar Boulevard and the shopping center means that the facades of the stores are oriented inwards towards the parking lot rather than the surrounding streets. Diamond Hills Plaza consists of commercial uses, while land uses surrounding the site are entirely residential. Bushes and walls on the perimeter of the site create a distinct boundary between the shopping center and adjacent land uses. The lack of mixed uses and the separation from adjacent land uses limits pedestrian activity on this site. Diamond Creek Village. The intersection of Golden Springs Drive and Brea Canyon Road is home to numerous shops and retail establishments. The largest establishments, Market World and Goodwill, are set back as much as 350 feet from Golden Springs Drive, and are fronted with a large surface parking lot. Most of the land fronting the streets is occupied by parking lots. Right-of-way of South Brea Canyon Road is about 90 feet, while right-of-way of Golden Springs Drive is about 100 feet. Upon completion of the Lemon Avenue Interchange, the existing eastbound SR -60 on/off ramps area across Golden Springs Drive from Diamond Creek Village will be closed and vacated. Metrolink Station Area. The area around the Industry Metrolink station contains a mix of warehousing and light industrial uses, as well as single-family residential uses and a mobile home park. Residential and industrial uses are not typically considered to be compatible land uses, and as such the edges of residential areas are often delineated with gates and walls to block views, noise, and other nuisances associated with the industrial activity. As this area was one of the first be settled in Diamond Bar, and because it is 38 Packet Pg. 47 1.1 Existing Conditions Report — Volume 1, February 2017 Land Use, Community Character, and Design and Mobility and Circulation relatively flat, the streets follow a tighter grid -like pattern than they do elsewhere in the city. The corridor along Brea Canyon Road from the Metrolink Station to the shopping center at the intersection of Golden Springs Drive has availability for infill commercial development to front the street. Comparisons to Other Commercial Nodes Case studies of other commercial nodes in Diamond Bar's vicinity illustrate different downtown typologies and placemaking strategies. These case studies are provided not necessarily as models to follow, but to highlight placemaking elements and tools that may prove useful and relatable to the Diamond Bar community. • Claremont. Downtown Claremont is a historical site built in a tight grid pattern. The streets in this area are two lanes wide with parallel and angled parking. Buildings are typically one to two stories tall. The shops offer outdoor seating and pedestrian amenities. Sidewalks are wide and flanked by trees and other landscaping. Alleyways and footpaths are inviting places for pedestrians to walk. • Brea. Retail storefronts and restaurants line Birch street in Downtown Brea. Pedestrian amenities, including wide sidewalks, corner bulbouts, and painted street crossings make Downtown Brea a safe environment for walking. The shopping center includes street parking along Birch Street and lots behind the southern storefronts. • Chino Hills. The Shoppes at Chino Hills is a recently constructed outdoor shopping center. The shops face inward to pedestrian roads and plazas. The town center is surrounded on all sides by parking lots. • Monrovia. Downtown Monrovia features one- to two-story historic buildings. Sculptures, landscaping, and pedestrian amenities such as benches line the streets. The roads are two lanes wide, and curb bulb -outs shorten the distance pedestrians walk on the street. A nearby community park accommodates outdoor festivals and events. Placemaking Analysis The commercial nodes are analyzed based on several urban design criteria. Figure 2-7 compares the following attributes between the eight commercial sites: • Figure Ground. Figure ground diagrams show building footprints in grey, roads in white, and pavement and landscaping in tan. Figure ground diagrams show the large scale of parking lots and undeveloped space relative to nearby buildings. Land Uses. A mix of land uses usually indicates greater activity and economic vitality in a commercial area. Though the different land uses indicate different peak hours of use, a mix of land uses indicates a consistency in the amount of activity seen in a commercial area throughout. The figure ground diagrams reveal the scale of commercial buildings and parking lots relative to their surroundings. In some areas, such as the intersection of Golden Springs Drive and South Brea Canyon Road, retail facilities are easily distinguishable from surrounding structures owing to differences in building size and front setbacks. Though these shopping centers witness pedestrian 39 Packet Pg. 48 1.1 Diamond Bar General Plan Update activity at store entrances, by setting these retail structures far back from the street, these shopping centers do not exhibit the type of street life common in more densely concentrated town centers. The land use comparisons show a separation of land uses. In most cases, commercial uses are clustered together in shopping centers. In the cases of Diamond Hills Plaza and the shopping district at the intersection of Grand Avenue and Diamond Bar Boulevard, these commercial uses are almost entirely surrounded by residential uses. A key to a vibrant, bustling town center is mixed- use development. Mixed uses ensure pedestrian activity at most hours of the day, reduces dependence on automobiles, and creates a diverse range of economic activity. The lack of consistent activity—and in the case of the Kmart site, the lack of any activity—can be attributed in part to a lack of diversity of land uses. 40 Packet Pg. 49 Figure 2-7: Placemaking Sites Metrolink Station Area O� b5'sc"moo Metrolink ��Q�� ��c"gam,-0 Station Q Q O� a440DO°K, cC 3 01en DbO E:] 44a4444Q C wasr+iNcron DR 51 a nniNw000 DR E-1 Q p cad D � Ela-� = a� .

Mobility within a community involves multiple modes of transportation, including automobile, public transit, bicycle, and others. Offering multiple modes of transportation can improve utility and social connectivity, and provide a range of choices for the individual traveler. This chapter describes the physical and operational conditions of the circulation network in Diamond Bar, including roadways, pedestrian and bicycle circulation, public transit, and goods movement. The transportation system in Diamond Bar includes diverse elements including roadway systems and bicycle systems, as well as a public transit system providing both local and regional service. A field assessment was conducted in September 2016 to further assist in the existing conditions evaluation. The transportation elements within the city are discussed in greater detail below. 3.1 Roadway System The City of Diamond Bar is a primarily suburban community with well-developed traffic patterns. The street system consists of a network of local roadways that connect to major roadways in a typical residential street pattern with many loops and cul-de-sacs. The roadway system comprises four functional systems: major arterial, secondary arterial, collector, and local streets. The classification of streets is based on a functional hierarchy defined by the number of travel lanes, roadway width (curb to curb), right-of-way (public property line to public property line), and traffic volumes. The network of arterial, collector, and local streets provide connectivity within the City of Diamond Bar and to neighboring communities. Regional connectivity to the city is provided by California State Route 57 (SR -57) and California State Route 60 (SR -60). 111.14441*1`.I_1S6lW_VIIAIyWINd1*1`►� The existing Circulation Element of the Diamond Bar General Plan designates four different roadway types in the city. Functional classification refers to how a road accommodates two characteristics: first, the extent to which the roadway prioritizes the through movement of traffic and second, the level of access provided to adjacent properties. Based on these generalized characteristics, roadways often vary in terms of right-of-way, roadway width, number of lanes, intersection and traffic signal spacing, speed, and other factors. The functional classification is assigned to a particular roadway based on the criteria above. Table 3-1 below identifies these roadway types for the city and provides the general geometric cross sectional characteristics of each.

These are streets located within residential communities and are used by residents to access arterial and collector streets. Speed limits are typically 25 mph or less, and there is a higher likelihood of tight radius turns and meandering alignments. Most local streets have sidewalks. Typical local streets do not have medians or striped centerlines. As the majority of streets are local streets, they are not individually addressed in this report. 3.2 Public Transit Public transit in the City of Diamond Bar is provided through local bus service, commuter rail service, and demand -responsive paratransit service, as shown on Figure 3-2. FIXED -ROUTE TRANSIT SERVICE' The City of Diamond Bar is served by Foothill Transit. As of 2016, five Foothill Transit routes provide service to the city: 286, 482, 493, 853, and 854. Foothill Transit 286 (Pomona to Brea) - Line 286 runs from Pomona to Brea and connects Diamond Bar to Pomona and Brea. This line passes through Diamond Bar via SR -57 and Diamond Bar Boulevard and provides service seven days a week. Line 286 runs from approximately 6:00 AM to 11:00 PM on weekdays and 7:30 AM to 8:30 PM on weekends. Headways are approximately 1 hour. 482 (Pomona to Puente Hills) - Line 482 runs from Pomona to Puente Hills and connects Diamond Bar to Walnut and Rowland Heights. Line 482 within Diamond Bar travels along Golden Springs Drive, Brea Canyon Road, Copley Drive, and Diamond Bar Boulevard. This line provides service seven days a week, from approximately 4:00 AM to 11:30 PM on weekdays and 5:30 AM to 11:30 PM on weekends. Headways are approximately 30 minutes. 493 (Diamond Bar to Downtown Los Angeles) - This is an express line that connects Diamond Bar to Los Angeles. Line 493 travels through Diamond Bar along Golden Springs Drive, Brea Canyon Road, and Diamond Bar Boulevard. Service is provided on weekdays only from 4:30 AM to 8:OOPM with 10-15 minute headways during the AM peak hour and 5-10 minute headways during the PM peak hour. 853 (Diamond Bar) - Line 853 serves Diamond Bar and runs from Copley Drive & Golden Springs Drive to Diamond Ranch High School via Golden Springs Drive and Avenue Rancheros. Line 853 runs Monday to Friday from approximately 7:15 AM to 8:30 AM and 3:00 PM to 4:00 PM on weekends. Headways are 5-10 minutes. ' Orange County Transportation Authority (OCTA) service to Diamond Bar was discontinued in their October 2016 service update. 49 Packet Pg. 58 1.1 Diamond Bar General Plan Update 854 (Diamond Bar) — Line 854 serves Diamond Bar and runs from Copley Drive & Golden Springs Drive to Diamond Ranch High School via Golden Springs Drive, Diamond Bar Boulevard, and Avenue Rancheros. Line 854 runs Monday to Friday from approximately 6:45 AM to 3:45 PM on weekends. Headways are 5-20 minutes. Commuter Rail Service Diamond Bar is also served by the Metrolink Riverside Line along the northwestern boundary of the city. This line runs from Downtown Riverside to Union Station in Downtown Los Angeles and provides service Monday to Friday. There are six inbound trains that run from approximately 5:00 AM to 3:00 PM and six outbound trains that run from 1:20 PM to 6:30 PM. PARATRANSIT SERVICE Unlike fixed -route transit service, paratransit service does not follow fixed routes or schedules. Paratransit can consist of vans or mini -buses that provide on -demand curb -to -curb service from any origin to destination within the service's specified service area. Qualifying residents can utilize Access Services. Access Services is a curb -to -curb paratransit service serving Los Angeles County residents unable to use regular bus service. Access Services provides next day transportation service within % of a mile on either side of any fixed route bus operated by the Los Angeles County public fixed route bus operators. Current fares are distance based and range from $2.75 to $3.50 for each one-way trip. Diamond Bar residents can also use the City's Diamond Ride program, which is a subsidized curb - to -curb cab service program designed to supplement travel means for persons with disabilities and those age 60 and older residing in Diamond Bar. Within the city limits, the one-way fare is $.50. However, the program also offers subsidized fares to medical facilities within an approximately five -mile radius beyond the city limits, which includes Pomona Valley Hospital Medical Center and St. Jude Hospital/Medical Center in Fullerton. Id:Z12Nhd1_T.0114kdI*� Transit facilities in Diamond Bar consist of bus stops for Foothill Transit buses along Diamond Bar Boulevard, Golden Springs Drive, and other roads. The Metrolink station can be accessed via Brea Canyon Road. A significant portion of the bus stops in the city have a bench or a shaded bus shelter. In addition, commuters can utilize two Caltrans park-and-ride lots on Diamond Bar Boulevard. 50 Packet Pg. 59 Figure 3-2: Existing Transit GENERAL PLAN 1.1 City of Diamo City of Diamond Bar Sphere of Influence L County Boundary Foothill Transit Bus Routes 195 - 497 286 - 853 — 482 — 854 493 O Park and Ride Lot 0 0.375 0.75 1.5 MILES Packet Pg. 60 1.1 Diamond Bar General Plan Update This page intentionally left blank. 52 Packet Pg. 61 1.1 Existing Conditions Report - Volume 1, February 2017 Land Use, Community Character, and Design and Mobility and Circulation 3.3 Goods Movement Goods movement plays an important role in both the circulation network and the economy of a city such as Diamond Bar. Often, it can be difficult to balance accommodating trucks and other vehicles without impeding other modes or the well-being of residents of the city. Due to its important location among two highways, Diamond Bar should incorporate goods movement along its roadways into effective transportation planning. According to the current General Plan, designated truck routes in the City of Diamond Bar consist of Walnut Drive west of Lemon Avenue, Lemon Avenue north of Golden Springs Drive, Golden Springs Drive between Lemon Avenue and Brea Canyon Road, Brea Canyon Road north of Golden Springs Drive, Diamond Bar Boulevard between SR -60 and Sunset Crossing Road, and Sunset Crossing Road between Diamond Bar Boulevard and the SR -57 Southbound ramps. The Surface Transportation Assistance Act (STAA) of 1982 also defines a network of highways as truck routes. Large trucks are allowed to operate on these routes. Goods movement into and through Diamond Bar is currently accommodated by STAA-designated SR -57 and SR -60, which connects Diamond Bar to Riverside County and Interstate 10 and can potentially serve as an alignment for the East Freight Corridor. The STAA also encourages local governments to accommodate trucks on roadways beyond those designated by the Act. These facilities are shown on Figure 3-3. The Lemon Avenue interchange will be completed in 2018, which will require an update to the City's truck routes in the interchange's vicinity, including discontinuing the truck route on Golden Springs Drive east of Lemon. 3.4 Non -Motorized Transportation Facilities Non -motorized modes of transportation are environmentally friendly alternatives to motor vehicles that enhance both personal and social well-being. These alternatives to motorized transportation are important traveling modes, part of a seamless transportation system that includes other modes of moving around such as transit. In addition to transporting, these modes of travel provide many public access, health, and economic benefits and are recognized as integral components of Diamond Bars' transportation system. Safe, convenient, attractive, and well-designed pedestrian and bicycle facilities are essential if these modes are to be properly accommodated and encouraged. Inadequate facilities discourage users and waste money and resources on unnecessary facilities. The City has been well aware of this need and has several policies to continue this effort. PEDESTRIAN FACILITIES The suburban, tract housing layout, with major through streets comprising a notable portion of the city, has resulted in an automobile dominant community. Six factors that affect walkability and the pedestrian experience in the city at large have been analyzed, including: Sidewalk Continuity - Communities are more walkable if sidewalks do not end abruptly and are present on the entire segment and both sides of a roadway. This is especially important for the mobility -impaired or those pushing small children in strollers. 53 Packet Pg. 62 1.1 Diamond Bar General Plan Update Sidewalk Conditions - This refers to the physical condition of sidewalk surfaces. Sidewalks that are broken or cracked can deter walkability and pose a safety hazard, particularly for the mobility impaired, such as those in wheel chairs and persons using walkers or strollers. Shading - Persons are more inclined to walk in areas where there is shade present, particularly in Southern California with its relatively warm weather and limited rainfall as compared to other locations. Additionally, shade trees create an aesthetic value that is pleasing to the pedestrian. Grade - Persons are more inclined to walk in areas that are relatively flat or have limited grade changes. Amenities - All else being equal, persons are more inclined to walk in areas that are interesting environments with shopping, retail, restaurants, and other similar uses. Pedestrian -friendly amenities include street furniture, attractive paving, way -finding signage, enhanced landscaping, and improved lighting. Buffers - A more walkable environment is one in which there is some degree of separation between the pedestrian and the motorist. This typically includes wider sidewalks, street parking and sidewalk bulb -outs at intersections where feasible. Crosswalks with appropriate signage serve as an important buffer as well. A general evaluation of the pedestrian environment in Diamond Bar is provided in Table 3-3 below. BICYCLE FACILITIES The City of Diamond Bar has made a concerted effort to expand the ease of alternative transportation options for residents, recognizing both health and environmental benefits. This includes the expansion of bicycle facilities along roads such as Golden Springs Drive and Brea Canyon Road since the last General Plan. However, opportunities exist to improve facilities. For example, bicycle lanes on Grand Avenue in neighboring Chino Hills to the east terminate at the city limits despite sufficient right of way; however, steep grade and other safety issues should be addressed before considering this segment for bikeway installation. Also, bicycle lanes on Golden Springs Drive are discontinuous, with gaps on at least three segments through the city. Furthermore, local neighborhood streets feeding onto roads such as Diamond Bar Boulevard and Grand Avenue can benefit from designated bicycle routes. Bicyclists enjoy an extensive system of shared and dedicated facilities along Diamond Bar's roadways. These facilities, shown on Figure 3-4, consist of Class I multi -use paths, Class II striped lanes, and Class III bicycle routes. 54 Packet Pg. 63 Figure 3-3: Goods Movement GENERAL PLAN 1.1 City of Diann -1 :1 = City of Diamond Bar Sphere of Influence County Boundary ■ ■ ■ ■ ■ City -Designated Truck Routes STAA-Designated Truck Routes 0 0.375 0.75 1.5 MILES Packet Pg. 64 Figure 3-4: Existing Bikeways GENERAL PLAN 1.1 City of Diamo City of Diamond Bar Sphere of Influence L County Boundary -Y- ----f-------------------------------- .�ce�,NGE COUN i"'Y Existing Bikeways Class I: Multi -Use Path Class II: Bicycle Lane Class III: Bicycle Route 0 0.375 0.75 1.5 MILES I Packet Pg. 65 Existing Conditions Report — Volume 1, February 2017 Land Use, Community Character, and Design and Mobility and Circulation Table 3-3: Existing Pedestrian Facilities Criteria Evaluation Sidewalk Continuity Most major roadways in Diamond Bar have continuous sidewalks on one or both sides. Most residential streets also have continuous sidewalks on both sides of the street. Sidewalk Conditions Throughout the City of Diamond Bar, sidewalks are generally in good condition, free of cracks, fissures, or uplift. While there are some examples of cracked pavement, no conditions were observed that would inhibit safe movement. Sidewalks are generally wide enough to accommodate multiple users, though in some cases there are obstructions due either to various utility boxes or overgrown landscaping. Shading Generally, shading is limited throughout Diamond Bar. There are some segments containing trees along the sidewalks, but these tend to provide very little shade. Some shade is provided by trees on private properties adjacent to sidewalks. In many cases, there is no shading whatsoever. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................... Grade Several of the major arterials in Diamond Bar have slopes. In addition, residential streets often have significant grade, which may be a barrier to walking. ........................................................................................................................................................................................................................................................................................................................................................................................................................................................ Amenities Offered Because the City of Diamond Bar is a largely residential city, most roadways provide very little in the way of amenities that serve or appeal to pedestrians. There are some gas stations, strip mall retail, and restaurants at some intersections, but these are typically designed to be oriented towards the automobile and are not generally intended to attract pedestrian clientele. However, a significant portion of the bus stops in Diamond Bar offer pedestrian -oriented amenities such as a bench or a shaded bus shelter. Buffers Parking is generally not permitted along the major thoroughfares of Diamond Bar. Buffers that do exist largely consist of bike lanes and some landscaping, such as trees or parkways, between sidewalks and automobile travel lanes. Bike lanes on Diamond Bar Boulevard are especially wide, in some cases nearly as wide as a vehicle lane, providing a buffer between sidewalks and moving vehicle traffic.

COMMUTE TRIPS Mode Choice Mode choice refers to the mode of travel that is used for any particular trip. The US Census Department, through the American Community Survey (ACS), regularly reports mode choice for travel to work. The results for Diamond Bar and comparable regions are provided in Table 3-4 below. Table 3-4: Commuter Mode Split Commute Mode Choice Diamond Bar Los Angeles County California United States Single Occupant Auto 79.5% 72.6% 73.2% 76.4% Carpool 8.9% 10.3% 1 1.1 % 9.6% Public Transit 2.9% 7.0% 5.2% 5.1 Bicycling/Walking 1.5% 3.7% 3.8% 3.4% Other Means 0.6% 1.3% 1.3% 1.2% Work at Home 6.6% 5.1% 5.3% 4.4% Source: American Community Survey (2010-2014) As shown in Table 3-4, residents of Diamond Bar use single -occupant vehicles to travel to work substantially more than other modes. The other modes have low usage as compared to regional averages across the state and country, such as carpooling (8.9 percent), public transit (2.9 percent) and bicycling and walking (1.5 percent). Finally, it is noted that the percentage of residents in Diamond Bar that work from home is higher than the county, state, and national averages. Travel Time to Work Figure 3-5 presents comparative travel time information for Diamond Bar and Los Angeles County for travel to work for a one way -trip. As shown, travel times for Diamond Bar residents are shorter than for the rest of Los Angeles County. Eight percent of Diamond Bar residents travel less than 10 minutes to work, versus four percent of countywide residents. Also 33 percent of Diamond Bar residents travel less than 20 minutes, which is higher than the rest of the county (24 percent). Twelve percent of Diamond Bar residents take 60 or more minutes to reach work, compared to 19 percent of overall county residents. 58 Packet Pg. 67 1.1 Existing Conditions Report — Volume 1, February 2017 Land Use, Community Character, and Design and Mobility and Circulation Figure 3-5: Chart of Travel Time to Work 300f0 25% 20% 15% 1000 5% 0% ' Less than 10 10 to 19 20 to 29 30 to 39 40 to 59 60to 90 90 or more Minutes mins mins mins mins mins mins ■ Los Angeles County ■ Diamond Bar Source: American Community Survey (2010 — 2014) Work Trips Inside Diamond Bar Another aspect of travel behavior relates to the propensity for residents to either remain within their community or travel outside of their community for their work trips. One data source for this information is the Longitudinal Employer Household Dynamics (LEHD). According to the LEHD database, 6.7 percent of Diamond Bar residents worked in the city and 93.3 percent worked elsewhere in 2014 (the most recent year available). The percentage of persons living in Diamond Bar who also work in Diamond Bar has remained consistently between 6.5 percent and 7.1 percent from 2005 to 2014. The percentage of persons living in Diamond Bar but working elsewhere has remained above 92.9 percent during the same span of time. TRAFFIC CONGESTION Regional and local congestion can be assessed using a variety of approaches. One common approach is Level of Service (LOS), which assigns a letter grade based on quantitative or qualitative performance metrics. Intersection Level of Service The City of Diamond Bar Traffic Impact Analysis Guidelines (2009) use the Intersection Capacity Utilization (ICU) methodology to analyze signalized intersections, consistent with the Los Angeles County Congestion Management Plan (CMP) guidelines. Grand Avenue is part of the Los Angeles County CMP system, and the intersection of Grand Avenue and Diamond Bar Boulevard is monitored under CMP requirements. The ICU methodology evaluates the critical movements for each signal and compares that to the critical movement capacity of the intersection, resulting in a volume -to -capacity (V/Q ratio. After the quantitative V/C estimates are complete, the methodology assigns an LOS grade representing the quality of intersection operations. LOS grades 59 Packet Pg. 68 1.1 Diamond Bar General Plan Update and corresponding V/C ratios are provided in Table 3-5. LOS D is the maximum acceptable level of service for city intersections. However, LOS E is the maximum acceptable level of service at CMP intersections. Table 3-5: Intersection Level of Service And V/C Ratio Criteria LOS VIC Ratio A Less than 0.61 B 0.61 to 0.70 C 0.71 to 0.80 D 0.81 to 0.90 E 0.91 to 1.00 F Greater than 1.00 The City uses the Highway Capacity Manual (HCM) methodology to analyze unsignalized intersections. Additionally, Caltrans utilizes the HCM methodology to analyze its signalized freeway ramp intersections. The HCM methodology estimates the average control delay for the vehicle at the intersection. After the quantitative delay estimates are complete, the methodology assigns an LOS grade that represents the operations of the intersection. LOS grades and corresponding delay values are provided in Table 3-6. LOS C is the maximum acceptable level of service under the Caltrans methodology.

That object could be another car, a pedestrian, or something fixed in place like a light post. When collisions cause damage or injury, the details are recorded by the local law enforcement agency and loaded into the California Highway Patrol (CHP) Statewide Integrated Traffic Records System (SWITRS). The latest SWITRS data report (2009-2013) was used to analyze collision data for Diamond Bar roads. From 2009 to 2013, there were a total of 418 vehicle collisions, with three collisions resulting in a fatality and 18 collisions resulting in severe injuries. The top three cited factors contributing to collisions were: unsafe speed (24 percent), right-of-way violations (19 percent), and traffic signals and signs (13 percent). The number of vehicle collisions of any type during the five-year period between 2009 and 2013 ranged from 76 to 90 per year, as shown on Figure 3-9. During the same time period, the number of collisions involving a pedestrian or bicyclist has ranged from 7 to 12.

As illustrated in Figure 3-10, collisions are primarily focused along arterials such as Diamond Bar Boulevard, Grand Avenue, and Golden Springs Drive. In addition, two intersections display higher concentrations of collisions: Golden Springs Drive & Diamond Bar Boulevard and Diamond Bar Boulevard & Grand Avenue. 72 Packet Pg. 81 Figure 3-10: 2009-2013 Traffic Collisions GENERALPLAN City of Diamo N/GHLANDWRD Q F9C� q GPOgswG RD \,\ J2 � � GIENRO 1 SUNSET CROSSING Hl\`\ iIEO y0 ° yJP� i IGpRPH RDS � I FNA DR- \ - c PANT6,,% y P° I� SIE I Industry a` RI° LORDS DR _ y ` / r--_—_—_—___- LvcWINGSTci 04 �E jIE "Ic MOUN*N LAURE O �\ sAy/ K, °`vv if LOSANGELES COUNTY I , I I *LLA PINEDR �• P��O N�RO / SAN BERNARDINO COUNTY iw5r.

SR-57/SR-60 CONFLUENCE PROJECT The SR-57/SR-60 Confluence Project at Grand Avenue is an ongoing project intended to improve traffic operations on Grand Avenue from Golden Springs Drive to the interchange and increase interchange capacity. This project aims to improve traffic operation, reduce traffic weaving, increase weaving distance, and improve safety at the SR-57/SR-60 confluence. The construction is underway and expected to finish at the end of 2022; the project includes the construction of facilities such as on -ramps, off -ramps, auxiliary lanes, a bypass connector, and a bridge. The southbound slip on-ramp is currently under construction. �*l:afi7144_W[•].I_\'I 4.l11ONl►kd4:IA:F-11z N The SR-60/Lemon Avenue interchange is currently under construction. This project is constructing three ramps at Lemon Avenue and an auxiliary lane to the connector to Southbound SR -57. It will also remove the existing eastbound on- and off -ramps at Brea Canyon Road. This project includes a new traffic signal along Lemon Avenue and traffic signal modifications. These and other planned projects can impact traffic operations on the highways as well as Diamond Bar roadways. Construction delays can cause vehicle queues at on -ramps to spillover onto city streets, and drivers seeking to bypass construction could cut through Diamond Bar. The City will need to monitor and be aware of impacts to local roadways, and coordinate with Caltrans to reduce negative impacts on local streets due to these and other future transportation projects. 75 Packet Pg. 84 1.1 Diamond Bar General Plan Update This page intentionally left blank. 76 Packet Pg. 85 1.1 Packet Pg. 86 DYETT & BHATIA Urban and Regional Planners 755 Sansome Street, Suite 400 San Francisco, California 94111 ®415 956 4300 8415 956 7315 www.dyettandbhatia.com CITY OF DIAMOND BAR GENERAL PLAN UPDATE EXISTING CONDITIONS REPORT -VOLUME II: Economic Review and Market Assessment March 2017 Prepared by 16 Pro Forma r dvisorS LL and DYETT & BHATIA Urban and Regional Planners 1.1 Packet Pg. 88 1.1 Packet Pg. 89 1.1 Existing Conditions Report — Volume 11, March 2017 Economic Review and Market Assessment Table of Contents Existing Conditions Introduction and Overview...................................................... 1.1 Project Overview.................................................................................................................................

Conditions Introduction and Overview 1.1 Project Overview The City of Diamond Bar is preparing an update of its General Plan, which will establish the city's overall approach to development, transportation, environmental quality, public services, infra- structure, and parks and open spaces for the next 20 years. The General Plan, which is required by law in the State of California, identifies current and future needs, sets policy, and provides a basis for land use decision-making by policymakers such as the Planning Commission and the City Council. Diamond Bar's current General Plan dates back to 1995 and is in need of an update as new opportunities, challenges, and approaches have emerged in recent years. The General Plan update process provides an exciting opportunity for Diamond Bar community members to share their vision for the city's future and provide input on the city's long-term goals and development opportunities. 1.1 Purpose and Organization of the Existing Conditions Report This Existing Conditions Report represents the first major step in the process of updating the General Plan for the City of Diamond Bar. This report provides spatial information on existing conditions in the city and its surrounding areas as well as an analysis of growth prospects and land demand. The Existing Conditions Report is used as a basis for: • Facilitating community input on planning issues and visions during community work- shops; • Preparing alternative land use and transportation planning scenarios; • Formulating policies and implementation actions for the General Plan; and • Creating the environmental setting portion of the Environmental Impact Report for the General Plan. The focus is on resources, trends, and critical concerns to frame decision-making for the long- term physical development of the city. Much of the information, including that on land uses, nat- ural resources, civic and transportation infrastructure, current development projects and poten- tial development capacity, is presented with maps. Packet Pg. 96 1.1 Diamond Bar General Plan Update The Existing Conditions Report is organized into three separate volumes. • Volume L Land Use, Community Character, and Design; and Mobility and Circulation • Volume H. Economic Review and Market Assessment Volume III. Environmental Constraints and Opportunities; and Public Facilities, Services, and Utilities VOLUME II: ECONOMIC REVIEW AND MARKET ASSESSMENT This is the second of three volumes of the Existing Conditions Report. An overview of the organi- zation and contents of Volume II is provided below. 1. Existing Conditions Introduction and Overview. This chapter provides an overview of the General Plan update, as well as the purpose and organization of the Existing Condi- tions Report. It also distills the baseline research and analysis of Volume II of the Existing Conditions Report into planning considerations that should be addressed as the General Plan update process moves forward. 2. Summary. This chapter provides an executive summary as well as a comprehensive summary of findings from this report, including socioeconomic factors, development op- portunities, and fiscal implications of development. 3. Geography and Land Use Overview. This chapter relates the City of Diamond Bar to other geographical areas referred to within this report, and provides a summary of land uses. 4. Socioeconomic Analysis. This chapter analyzes the historic and projected socioeconomic trends for the city, region, and county that most influence land use potentials for future development. 5. Real Estate Market. This chapter provides an overview of historic trends for residential, office, industrial, retail, and hospitality land uses. 6. Long -Term Land Use Demand. This chapter provides long-term land use demand pro- jections for the city and various submarkets throughout the region. 7. Fiscal Conditions. This chapter examines the existing fiscal conditions in the city, specif- ically focusing on General Fund operating revenue and operating expenditures. 1.2 Key Findings and Planning Considerations The Existing Conditions Report serves to extract the most relevant information from the exten- sive baseline research efforts, providing a framework for further analysis and discussion with the community. The most significant findings from topics covered in Volume II are summarized be- low. • New development opportunities are needed to grow the city's base of residents and employment to ensure its long-term sustainability. Packet Pg. 97 1.1 Existing Conditions Report — Volume 11, March 2017 Economic Review and Market Assessment Diamond Bar is largely built out, resulting in slow growth projections for both population and housing. As a result, and in order to address future sustainability concerns, new de- velopment opportunities will be needed. Given anticipated demand for various residential and commercial land uses, a number of key development sites should be explored to en- courage future development. These include the Metrolink Station Area, the Honda Site, and the golf course. Other sites that could accommodate future development in the city are the Kmart Site, the Foremost Site, and the Tres Hermanos area, which have already undergone various levels of planning. Careful consideration should be given to the desired mix of land uses to ensure the long-term financial sustainability of the city from a fiscal perspective. Various potential land use changes under consideration will have different fiscal impacts to the City's General Fund. Residential land uses typically have the highest revenue and service level cost potential. The development of industrial and office space in the city will likely have a positive fiscal impact, as typically jobs created by these land uses require few- er city services than residential development. An increase in employment opportunities could also attract new residents to the city, which might help balance the jobs -to -housing ratio. New retail development can have a positive impact on the General Fund largely through the generation of sales tax. Hotel and other hospitality land uses typically have high net positive fiscal impacts because, like other commercial uses, the service costs are lower than residential uses, and the city receives the full voter -approved transient occu- pancy tax rate. • Diamond Bar experiences significant retail expenditure leakage to neighboring areas in the region due to the newer, large format retailers located in those cities. The decrease in the per capita generation of sales tax revenues would indicate that the city's retail base has not grown sufficiently to maintain (much less increase) its capture rate. For the city to remain economically viable over the long-term it should strive to con- tinue expanding its retail base by creating a more diverse retail environment to increase the market capture from its higher income households within the city and others in the region. Assuming that current household per capita income holds constant, based on population projections, the city could add up to 263,000 square feet by 2040. Packet Pg. 98 Diamond Bar General Plan Update This page intentionally left blank. 1.1 Packet Pg. 99 2 Summary 2.1 Executive Summary Situated on the southeastern edge of Los Angeles County, the City of Diamond Bar is easily acces- sible in the region, with over 10 million people and major job centers such as Los Angeles and Anaheim located within a 30 -mile radius. Since incorporating in 1989, the city has balanced its small town charm with the challenges of urbanization. It is continually rated one of the best cities to do business due to its streamlined permitting process, no utility taxes, and low business fees. Among the factors that attract new residents to the city are its quality schools, low crime rates, cultural diversity, and parks and open space. In the two decades since the City's General Plan was adopted 1995, nearly all of its goals and ob- jectives have been implemented. The purpose of the general plan update is to guide the next two decades of physical growth. This report summarizes the economic, real estate, and fiscal condi- tions and trends that will shape medium-' to long-term2 growth opportunities in the city. The primary purpose of this economic review and market assessment is to inform, for planning purposes, the city's overall land use policy with respect to the type of development and land uses that could be effectively targeted during the planning horizon. An evaluation of the city's fiscal situation was also provided to give context to how the General Plan's land use polices are related to General Fund resources (revenues) and appropriations (expenditures). In subsequent tasks as- sociated with the General Plan, a more detailed analysis will be provided regarding the financial feasibility and fiscal impact of specific land use alternatives. It is important to note that in the context of long-term planning, short-term market cycles have less relevance given a planning horizon stretching to 2040. The conclusions discussed throughout this report are based on long-term data projections and an understanding of economic and mar- ket dynamics affecting the city and region. This report has been prepared for the City and the General Plan Advisory Committee (GPAC) by Pro Forma Advisors as a sub -consultant to Dyett & Bhatia in support of the City's General Plan Update process. 1 Five to 10 years. 2 Over 10 years. 1.1 Packet Pg. 100 1.1 Diamond Bar General Plan Update 2.2 Summary of Findings The following key findings are provided to give an order of magnitude sense of future land use demand as well a review of key issues impacting future development in the city. These issues are explored from the socioeconomic, market, and fiscal perspective. SOCIOECONOMIC FACTORS INFLUENCING DEVELOPMENT Based on a review of historic and projected socioeconomic trends for the city, the following pro- vides a summary of key issues to consider for future land use planning from a socioeconomic per- spective. Ethnic Composition Diamond Bar has an increasingly diverse population. While changing demographics do not nec- essarily affect land use decisions, different cultures tend to have different preferences and priori- ties, and may change the market orientation of some residential and non-residential land uses. As such, it is important to consider how the projected ethnic composition of the city's population might impact future land use decisions. The city's Asian population composition is largely se- cond -generation residents and comparable to mature ethnic cities such as Cerritos or Irvine, where the population speaks English very well. Ethnic diversity is an attribute that may shape spe- cific commercial and residential preferences. Age The city's population is aging, and the senior population's growth and transition into retirement will provide unique challenges for the city. The market created from this demographic shift might require changes in the city's housing stock to provide opportunities for residents to age in place. Alternatively, changes in their housing preferences could create opportunities for younger fami- lies wanting to move into the city. Employment Base Since the Great Recession, the combination of lost jobs and decreased labor force participation has kept unemployment low in the city. However, this could be an issue if the city's labor force participation does not increase and the number of resident jobs does not return to pre -recession levels. Given the age dynamics in the city, it is possible that the Great Recession may have driven some residents to early retirement. As a result of the need to increase the city's employment base for residents and non-residents alike, new employment opportunities are critical. The city has many positive attributes relating to employment. First, there is a greater concentra- tion of higher paying jobs in the city compared to Los Angeles County. Second, commuter direc- tional analysis suggests that because of the city's connection to multiple freeway networks, there is a relatively equal distribution of employees commuting from various areas in the region. Finally, the city has many business -friendly policies to attract future job growth. Future commercial de- velopment and the absorption of existing vacant commercial space are opportunities for future employment serving land uses. Packet Pg. 101 1.1 Existing Conditions Report — Volume 11, March 2017 Economic Review and Market Assessment Future Population and Employment Growth Based on population projections, the city will grow at a slower pace than experienced prior to in- corporating 27 years ago. Between 2016 and 2040, the city is anticipated to have an annual growth rate of just 0.5 percent. Unlike long-term population forecasting, which is more reliable because there is a deterministic element to the process (birth rate, death, etc.), long-term employment projections are more unreliable because of the uncertainly involved in accurately predicting fu- ture economic trends. Most long-term economic forecasts simply assume that present growth rates will continue at a set rate into the future. Based on current employment projections, the city will have an annual growth rate of just 0.6 percent. In both cases, the projections from the South- ern California Association of Governments (SCAG) are largely based on available land and sug- gest limited opportunity for growth. However, there are a number of development site opportuni- ties that could be leveraged to attract additional residential or employment uses in the future. DEVELOPMENT OPPORTUNITY The following provides context regarding future development potential, given the anticipated market demand for various land uses. As shown in Table 2-1, an order -of -magnitude demand estimate for residential, office, industrial, hotel, and retail land uses has been made for the city through 2040. This range represents the target range of development that could be attracted over the General Plan update horizon. Based on the economic development goals of the city or GPAC a more aggressive capture of the submarkets estimated demand could be warranted. These esti- mates should be considered preliminary for planning purposes. Table 2-1: Long -Term Planning Targets by Land Use Land Use Demand (2016 — 2040) Low High Residential (Housing Units) 950 2,100 Office (Square Feet) 240,000 300,000 Industrial (Square Feet) 150,000 220,000 Hotel (Rooms) 400 500 Retail (Square Feet) 400,000 500,000 Source: Pro Forma Advisors Given that the city is largely built out, the demand for development will likely be targeted at one of the key sites identified in the city. The following provides key development site opportunities: Metrolink Station Area The City has identified a potential transit -oriented development zone near the Industry Metrolink Station. The area is currently built -out with a combination of civic, industrial, and office uses. However, given the close proximity to the Metrolink station, the redevelopment of these lower value industrial and office uses into higher -density mixed-use residential development might be possible in the future. While the higher -density, mixed-use product envisioned for this area may not be feasible under current market conditions, in the medium- and long-term, the city may seek opportunities to provide a more diverse set of residential product (i.e. multi -family for -sale or for - rent), which could positively transform this zone in the future. Packet Pg. 102 1.1 Diamond Bar General Plan Update Honda Site In 2014, the City Council approved a mixed-use zoning on the former Honda dealership property located to the north of the Orange freeway on the southwestern corner of Grand Avenue and Old Brea Canyon Road. The Honda Site has been identified as a development opportunity for either a four -acre site to build a 180 -room mid -upscale business hotel with 48,200 square feet of office space, or a seven -acre site to build a 405 -room business suite hotel complex with up to 76,200 square feet of office space. City-wide demand for hotel and office uses could largely be satisfied at this site location. Diamond Bar Golf Course Based on the site's visibility and freeway exposure, as well as the adjacent ramps, the Diamond Bar Golf Course represents an excellent commercial mixed-use redevelopment opportunity. However, redevelopment of the site is a controversial and polarizing issue. In addition to community con- cerns, any development plans would require the city to provide a matching property for the coun- ty elsewhere. Even given these concerns, considering the available land and potential development opportunities, the site is one of the best commercial retail sites in the region. Other Development Sites There are a number of other sites that could accommodate future development in the city. Other sites analyzed herein include the Kmart site, the Foremost site, and Tres Hermanos, which have already undergone various level of planning. Retail Leakage The city appears to experience significant retail expenditure leakage to neighboring areas in the region due to the newer, large format retailers located in those cities. The decrease in the per capi- ta generation of sales tax revenues would indicate that the city's retail base has not grown suffi- ciently to maintain (much less increase) its capture rate. For the city to remain economically via- ble over the long-term it should strive to continue expanding its retail base by creating a more diverse retail environment to increase the market capture from its higher income households within the city and others in the region. FISCAL IMPLICATIONS OF DEVELOPMENT The following provides a summary overview of the various potential land use changes under con- sideration in the General Plan Update and how these land uses generally impact the City's Gen- eral Fund. Residential (For -Sale and For -Rent) Residential land uses typically have the highest revenue and service level cost potential. This is true because the land use generates key General Fund revenue items such as property tax, proper- ty transfer tax, sales tax, etc. and also requires the highest service levels (and associated costs) due to their relative impact on various city departments (specifically police and fire) compared to commercial development. Given that the city is comprised of predominately single-family de- tached housing, there is a question of whether compact, denser, multi -family (for -sale or for -rent) development would have a more beneficial fiscal impact on the General Fund. The fiscal implica- Packet Pg. 103 1.1 Existing Conditions Report — Volume 11, March 2017 Economic Review and Market Assessment tion of compact development has been analyzed in municipalities throughout the country and will potentially need to be scrutinized while evaluating General Plan alternatives. Typically, the combination of density and/or sales price needs to reach a certain threshold to make the residen- tial development net positive to the city from the General Fund perspective. Office and Industrial The development of industrial and office space in the city will likely have a positive fiscal impact, as typically jobs created by these land uses require fewer city services than residential develop- ment, while the assessed value of commercial property generates property tax, property transfer tax, and the VLF - Property Tax in Lieu tax revenues. The costs associated with industrial and office space are typically lower because calls for service are typically higher for residential and re- tail land uses. An increase in employment opportunities could also attract new residents to the city, which might help balance the jobs -to -housing ratio and have additional benefits from the transportation (and associated Public Works costs) perspective. Retail New retail development can have a positive impact on the General Fund largely through the gen- eration of sales tax. In the context of the city, the recapture of lost taxable sales from existing resi- dents and employees, as well as the capture of sales to new residents and employees, could pro- vide significant positive fiscal revenue. Based on the retail demand analysis, it appears that future retail development could positively impact the General Fund and provide additional revenues needed for long-term fiscal sustainability. Similar to office and industrial development, the city's relative service cost for commercial land is typically lower than residential uses. Hotel Hotel and other hospitality land uses typically have high net positive fiscal impacts because, like other commercial uses, the service costs are lower than residential uses. Also, unlike other taxes (e.g. property and sales) where the City receives some portion of the tax rate, the city receives the full voter -approved transient occupancy tax rate. Based on the hotel demand analysis, it appears that future hotel development could positively impact the General Fund and provide additional revenues needed for long-term fiscal sustainability. Other Considerations Various city costs have service capacity thresholds, where there is a tipping point that will require a significant increase in costs at some point in time. One example would be a fire station. Cur- rently there are three fire stations in the city with associated expenditures based on the service - level capacity and geographic reach of each station to meet desired response times. It is possible that future development could create service level demand to exceed the existing fire station ca- pacity, which would in turn require the city to develop an additional station with the associated new operating costs. An understanding of each significant public facility service capacity thresh- old will be considered as part of the preferred alternative selection process, or else the costs allo- cated to future growth could be understated. 9 Packet Pg. 104 1.1 Diamond Bar General Plan Update This page intentionally left blank. 10 Packet Pg. 105 3 Geography and Land Use Overview The following section presents a brief overview of the City of Diamond Bar (city) in relation to other geographical areas referred to within this report. It also summarizes existing land uses. The city's core assets such as open space, proximity to regional freeways, and reputation within the region are important attributes that can be leveraged to attract future development and shape long-term land use planning. 3.1 Location Overview Located on the eastern edge of Los Angeles County (county), in the hills of the eastern San Gabri- el Valley (SGV), the city is located within minutes of major metropolitan business centers in Los Angeles, Orange, Riverside, and San Bernardino counties. From a regional perspective, the city is easily accessible from State Routes 57 (SR -57) and 60 (SR -60). The city is also within a relatively short distance of three major airports, two shipping ports, and a variety of commercial/commuter rail facilities. Given its central location within the larger Los Angeles Metropolitan Statistical Area (MSA) it is estimated that there are over 10 million people living within a 30 -mile radius, which includes major job centers such as Los Angeles and Anaheim (Figure 3-1). For comparison pur- poses, an area consisting of the following cities has been defined as the region (Figure 3-2), which are used as an additional benchmark in this analysis: • Brea • Chino • Chino Hills • Covina • Diamond Bar • Industry • Pomona • Walnut • West Covina 1.1 Packet Pg. 106 Diamond Bar General Plan Update 3.2 City Overview During the 1960s, suburban development spread eastward from Los Angeles. Despite its initial conception as a master -planned community, the city was not developed in an orchestrated man- ner while it remained an unincorporated community. In March 1989, local voters approved in- corporation in order to assert stricter control over local development. On April 18, 1989, it be- came the 86th city in the county. 12 1.1 Packet Pg. 107 Existing Conditions Report — Volume 11, March 2017 Economic Review and Market Assessment Figure 3-I: City of Diamond Bar, 10-, 20-, and 30 -Mile Radius Rancho Cucamonga El Monte ."""` Los ,Angeles flvina Pomona N.Itano Diamond Bar Redondo Beach Long Beach 1Dkm 7bmi Source: ESRI Business Analyst Anaheim H+Jntington Reach Santa Ana cul ul is Randio Lake Santa Forest Margarit Niguel Piversode 1.1 13 Packet Pg. 108 Diamond Bar General Plan Update Figure 3-2: City of Diamond Bar, Region, and Los Angeles County Source: ESRI Business Analyst :s County Diamond Bar Region Frahai- -' 1 Santa Alw Hu"unywr Beach 1.1 14 Packet Pg. 109 1.1 4 Socioeconomic Analysis The future market demand for different land uses in the city will be influenced by regional eco- nomic forces and market trends. This section analyzes the historic and projected socioeconomic trends for the city, region, and county that most influence land use potentials for future develop- ment. The following base analysis lays the foundation for the potential land use plan alternatives that will be formulated in subsequent phases of the General Plan Update process. 4.1 Demographic Trends The following section provides summary level information on key population, ethnic, age, and household trends that may affect future land use planning in the city. POPULATION Between the 1990 Census and the 2016 Department of Finance population projection, the city gained approximately 3,400 residents, as shown in Table 2. This represents an increase of approx- imately 130 people per year, which is an annual growth rate of only 0.2 percent a year. The city represents approximately 2.1 percent of the larger region's population growth and 0.2 percent of the County's growth over the same time period. Currently, the city represents 9.4 percent of the region's population and 0.6 percent of the county's total population. Since 1990, the city's overall population growth has not kept pace with the region or county's growth due to the fact that the city is largely built out and there are limited current opportunities for housing development. Focusing on more recent population trends, the city's population growth has been flat (one per- cent) compared to the region and county between 2001 and 2016, which grew by eight and seven percent, respectively (Figure 4-1). For comparison, the state's population grew by 15 percent over the same time period largely due to more opportunities for housing development in comparison to the county as a whole, which is largely built out.

In contrast to the population growth, which has been relatively stable, the racial composition of the city continues to evolve. Between the 2000 and 2010 Census, while the number of individuals identifying themselves as White decreased by eight percent, the number of Asian residents has increased by approximately nine percent, which now brings this group to represent over half of the population (Table 4-2). Within this ethnic group, about 25 percent of the city's population is Chinese and 10 percent is Korean, with other groups represent- ed in smaller numbers. It is important to consider how recent changes in ethnic composition of the city's population might impact future land use decisions. While changing demographics do not necessarily affect land use decisions, different cultures tend to have different preferences and priorities and may change the market orientation of some residential and non-residential land uses. In comparison to both the region and the county, the city has more than twice the share of residents identifying themselves as Asian, as shown in Figure 4-2.

Census data suggests that this is a sign of a more mature ethnic community made up of largely second generation residents.3 3 Second generation residents estimated to be those people that are identified to speak English very well or only speak English.

Similar to ethnic changes in the city, Diamond Bar's aging population will have unique implications for future land use planning. By analyzing age cohorts, the city has an underrepre- sentation of age groups under 44 years. Conversely, there is a significant overrepresentation of age cohorts 55 to 74 years old, whose shares are at least three percentage points higher than in the region and the county, as shown in Table 4-3.

Similar to the region, there is a high proportion of the household population in "family" households.4 In 2010, it was also estimated that the aver- age family size (3.4) had decreased from 2000 (3.5) in the city. Diamond Bar also exhibits a lower average family size than the region (3.7) and county (3.6). The household characteristics in the city are comparable to other suburban communities and the growth, while slow, is in line with the previously noted population growth.

EMPLOYMENT Employment is examined in terms of unemployment rates, jobs (in-place employment), worker area profile, industry composition, and top employers in the City. A critical barometer in evaluat- ing demand for commercial (workplace) real estate is employment growth. The following tables and graphs highlight relevant employment trends and forecasts. Sectoral (industry) analysis lends insight into industry growth and contraction patterns in a given geography. Data were analyzed from the Bureau of Labor Statistics (BLS) and US Census's Longitudinal Employer -Household Dynamics (OnTheMap) for primary jobs in the city, region, and county areas. Unemployment As of July 2016, the City's annual unemployment rate had fallen to 3.5 percent, down from a peak of 8.9 percent seen seven years earlier in 2009, as shown in Figure 4-4. As such, the city's unem- ployment rate has generally moved below the pre -recession norm of three to four percent. The city has remained approximately 200 basis points5 below the county's unemployment rate in pre - and post -recession times. During the Great Recession, it appeared that the city's employment showed resiliency as unemployment did not spike as high as the county and started recovery ap- proximately a year before the county's unemployment peak (13.2 percent) in 2010. However, ab- solute employment (approximately 29,200 as of July 2014) has seen a net total decrease of approx- imately seven percent since 2006. Between 2009 and 2010, approximately 3,700 people left the labor force in the city. Diamond Bar's labor force has slowly increased since then, recapturing 1,100 net new individuals entering or returning to the labor force. The combination of lost jobs and labor force decreases helped keep unemployment low, but also suggests additional concerns if labor force participation and the number of residents' jobs do not return to pre -recession levels. Alternatively, the recession may have driven some residents to early retirement. 5 Basis point refers to a unit of measure for percentages in finance. One basis point is equal 0.01% (e.g. 1% change= 100 basis points). 21 Packet Pg. 116 Diamond Bar General Plan Update Figure 4-4: Unemployment Rates 14.0 y 12.0% Ai 10.0 8.0% c 6.0% (L A14, E 4.0% 2.0% 0.0 5.5 3.5 ,a �0 a r, n M M M a, a1 O O— —— N N M M M V' V- Ln Ln 10 �a O O O O O O O O O O 7 — — — — — — — — — — — — — — C C > L d U T +"' L bq C C > L d- U T +"' =- b4 C C Z Q N U 0 z O E Q Z Q cn L C)1: O Q -Diamond Bar Los Angeles County Source: Bureau of Labor Statistics jobs The previously provided information regarding unemployment, employment, and the city's labor force, which are based on the city's residents. The following analysis examines jobs located in the city that may or may not be held by city residents. An evaluation of the primary "in-place" em- ployment is important as it impacts the range of demand that can projected for future commercial serving land uses. Primary jobS6 in the city and county rose from 2004 leading up to the Great Recession. Unlike the county, where primary jobs experienced a few years of declines and then slowly increased above their pre -recession level, primary jobs in the city dropped significantly between 2007 and 2009 and then experienced periods of growth and decline. The total number of primary jobs in the city would have remained below pre -recession levels if not for a significant increase of primary jobs (approximately 2,360) between 2013 and 2014. Overall, primary jobs have increased by approxi- mately three percent and seven percent in the city and county, respectively, as shown in Figure 4- 5. There were approximately 16,300 primary jobs in the city in 2014, which is the most recent year of the Quarterly Census of Employment and Wages in-place employment data available for analy- sis. 6 A primary job is defined as the highest paying public or private sector job, one job per worker. This is a subset of total jobs, which include all public or private sector jobs (potentially more than one job per worker). For example, if a per- son had two part-time jobs, then the primary job would be the highest paying job for that worker. Typically there is not significant variation in primary and total jobs except in economies with significant portions of the labor force engaged in part-time employment (e.g. tourist economies). 22 1.1 Packet Pg. 117 1.1 Existing Conditions Report – Volume 11, March 2017 Economic Review and Market Assessment Figure 4-5: Primary Job Change (2004 - 2014) 120.0 115.0 110.0 105.0 106.6 102.9 100.0 95.0 90.0 85.0 80.0 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 —Diamond Bar Los Angeles County Note: 2004 is base year and growth above or below 100 represents total percent growth or decline over the time period. Source: OnTheMop (US Census Bureau, Center for Economic Studies) Worker Area Profile An evaluation of the city's primary jobs in 2014 reveals some noteworthy characteristics. Unlike the city's resident age distribution, the employment base does not deviate much from observed county ratios of jobs by age, as shown in Figure 4-6. Unlike the county, the city's in-place em- ployment consists of generally higher paying jobs. As shown in Figure 4-7, the percentage of low paying jobs yielding $1,250 per month or less are relatively equivalent, while the number of jobs paying more than $3,333 per month are higher in the city (35 percent) compared to the county (29 percent). The presence of higher paying jobs in the city is a positive sign that the city has an attractive, high -paying local employment base. 23 Packet Pg. 118 Diamond Bar General Plan Update Figure 4-6: jobs by Age (2014) 100% 90 80% 70 60 50% 40 30% 20% 10% 0% 1.1 Diamond Bar Los Angeles County Source: OnTheMop (US Census Bureau, Center for Economic Studies) Figure 4-7: jobs by Income (2014) 100% 90% 80 70% 60% 50% 40% 30% 20% 10% 0% Diamond Bar Los Angeles County Source: OnTheMop (US Census Bureau, Center for Economic Studies) 24 Age 55 or older Age 30 to 54 ■Age 29 or younger More than $3,333 per month $1,251 to $3,333 per month ■ $1,250 per month or less Packet Pg. 119 Existing Conditions Report — Volume 11, March 2017 Economic Review and Market Assessment Industry Composition The location quotient is a tool that measures the relative concentration of different industries in specific localities relative to a larger level of geography. In most cases, the location quotient would compare a county to a state or national level of employment concentration. However, it is useful to get a proxy for relative employment concentration among industries within a sub -state level geography. The calculation helps evaluate the city's strength or weakness in a given industry, rela- tive to the county as a whole. A concentrated (high) location quotient means that a given industry is represented more in the city than one would expect, given its total level of employment. The following describes the location quotient: • LQ > 1.0 means that an industry is more concentrated in the city than in the county. • LQ < 1.0 means that an industry is less concentrated in the city than in the county. • LQ = 1.0 means that an industry is equally concentrated in the city as in the county. Because industries with a location quotient greater than one indicate relatively high production of a particular service, it is likely that some amount of that industry is being exported. Employment in that industry (or the portion of employment that causes the quotient to exceed 1.0) is then as- signed to the economic base and is given credit for supporting the economy as a whole. Converse- ly, if an industry has a location quotient less than one, it is assumed to be a local -serving or non - basic industry. For economic development purposes, it is often useful to focus on the outlier industries with loca- tion quotients greater than 1.25 or less than 0.75. The assumption is that industries falling within 0.75 and 1.25 are probably producing at levels sufficient to meet local demand in the city. Comparing the city to the county, a number of industries demonstrate relative strength as poten- tial export business, as shown in Table 4-5. These include: • Finance and Insurance (3.43) • Real Estate and Rental and Leasing (2.37) • Management of Companies and Enterprises (2.43) • Administration & Support, Waste Management and Remediation (1.95) Industries that show weakness in the city, suggesting that they are imported (purchased outside the city), include: • Agriculture, Forestry, Fishing and Hunting (0.09) • Mining, Quarrying, and Oil and Gas Extraction (0.00) • Utilities (0.02) • Manufacturing (0.47) • Retail Trade (0.69) 1.1 25 Packet Pg. 120 1.1 Diamond Bar General Plan Update • Transportation and Warehousing (0.35) • Information (0.08) • Health Care and Social Assistance (0.49) • Art, Entertainment, and Recreation (0.44) • While some of the location quotients are potentially meaningless for future economic de velopment efforts in the city (e.g. mining), other low location quotients are potential tar- gets to attract given that they should be higher in the City based on a relative fair -share comparison to the county. Of those industries that might be of particular interest are re- tail trade, information, health care and social assistance, and art, entertainment and rec- reation industries.

Estimated city employment of 16,300 in FY20I S Source: Labor Market Information, Info USA, City Manager's Office COMMUTE FLOWS Similar to other suburban areas, the city has a high number of its residents commuting long dis- tances to work. Based on the OnTheMap employment data for 2014, approximately seven percent of the city's in-place employment is from residents that both live and work in the city, as shown in Figure 4-8. Conversely, of the approximately 22,100 city residents with jobs, approximately 90 percent of them work outside of the city. Of those employees that work in the city, there is a relatively equal distribution of individuals commuting from areas surrounding the city, as shown in Figure 4-9. Inflow directional analysis suggests that there is a larger concentration of individuals commuting to the city from the East and West, likely travelling along the I-10 or Pomona freeways, with slightly fewer commuting North or South along the Orange or 71 freeways. Interestingly, a significantly high percentage of the city's residents work to the West of the city. Overall, these data suggest that the city can attract a dispersed workforce and is an attractive location for those working in employment centers out- side the city, which is similar to dynamics often found in other bedroom communities throughout the region. 27 Packet Pg. 122 1.1 Diamond Bar General Plan Update Figure 4-8: Resident vs. In -Place Employment (2014) 25,000 � 22,500 22,500 20,000 17,500 15,000 0 12,500 E L. 10,000 7,500 5,000 2,500 0 Diamond Bar Residents Working Outside of Diamond Bar ■ Working in Diamond Bar 20,000 17,500 15,000 .0 12,500 i 10,000 r.IL 7,500 5,000 2,500 0 In Place Employment Living Outside of Diamond Bar ■ Living in Diamond Bar Source: OnTheMap (US Census Bureau, Center for Economic Studies) 28 Packet Pg. 123 1.1 Figure 4-9: Direction Analysis (2014) 25,000 22,500 20,000 17,500 15,000 m O Q12,500 a_ a 10,000 Southwest, 1,947 Existing Conditions Report - Volume 11, March 2017 Economic Review and Market Assessment Southwest, 2,925 South, 1,763 7,500 Southeast, 1,396 South, 2,735 5,000 2,500 Northeast, 2,070 Northeast, 1,380 X Work in Diamond Bar Live in Diamond Bar Source: OnTheMop (US Census Bureau, Center for Economic Studies) HOUSEHOLD INCOME The city's median household income is approximately 25 percent higher than the region and 60 percent higher than the county, as shown in Table 4-7. The household income projections, pro- vided by ESRI Business Analyst, suggest that the city's median income should continue rising at a rate consistent with the region and county over the next five years (2016 - 2021). The incomes of the city's households tend to be more concentrated in household income cohorts above $100,000 than the other areas, with smaller proportions of households in the income categories under $25,000 as compared to both the region and the county.

Retail sales production is critical to produce jobs as well as fiscal revenue that the city depends on to support desired municipal service levels. Historic Citywide Retail Sales Since 2005, the total taxable retail sales in the county have increased by almost 13 percent, from $131 billion in 2005 to $147 billion in 2014, as shown in Figure 4-10. During the same time peri- od, total taxable sales in the city decreased by almost three percent, from $337 million to $315 million. Comparing year -over -year changes, both the city and the county experienced similar trends, with a loss of taxable retail sales from 2007 to 2009 and continued growth since 2009. The major difference is that the city was impacted with more significant losses and had not returned to pre -recession levels by 2014. Retail Sales by Tax Area According to data provided by HDL Companies (HDL), the largest shares of sales tax received by the City come from the South Diamond Bar Boulevard (24 percent), Brea Canyon Off Ramp Clo- sure (20 percent), and Golden Springs (23 percent) tax areas, as shown in Figure 4-11. While the South Diamond Bar Boulevard and the Golden Springs tax areas bisect the City running north south, with accessibility from the Orange freeway, the Brea Canyon Off Ramp Closure tax rate area is a concentrated area of retailers located near the intersection of Brea Canyon Road and Golden Springs Drive. A map of sales tax areas is provided in Figure 4-12.

Source: HDL Companies Citywide Taxable Sales by Type of Business In 2014, the city had over $329 million in total taxable sales. Examining the taxable sales by type of business reveals some interesting trends regarding the distribution of captured spending in the city. As shown below in Table 4-9, in comparison to the county and state, the city has a very high concentration of spending within Gasoline Stations and low distribution of captured spending in other categories such as Clothing and Clothing Accessories Stores. Given the city's higher than average incomes, the information suggests that retail sales are leaking outside the city. This will be further explored in the Long -Term Land Use Demand section. 34 Packet Pg. 129 1.1 Existing Conditions Report — Volume 11, March 2017 Economic Review and Market Assessment Table 4-9: Taxable Sales by Type of Business (2014) Source: Board of Equalization Figure 4-14 displays changes in taxable retail sales from 2010 to 2016, during which time the city has seen increasing sales in Apparel Stores, Eating and Drinking Places, Furniture and Applianc- es, Food Stores, and Service Stations.

In the city, based on 2014 calendar year data from the Board of Equalization, the annual per capita spending is approximately $5,800, which, as shown in Figure 4-15, has not grown since 2005, un- like the city and the county. This per capita spending is significantly lower than the other cities in the region, county, and state, as shown in Figure 4-16. In addition, the city appears to experience significant retail expenditure leakage to neighboring areas in the region due to the newer, large format retailers located in those cities. Furthermore, the decrease in the per capita generation of sales tax revenues would indicate that the city's retail base has not grown sufficiently to maintain (much less increase) its capture rate. For the city to remain economically viable over the long- term, it should strive to continue expanding its retail base by creating a more diverse retail envi- ronment to increase the market capture from higher income households within the city and oth- ers in the region.

The following briefly summarizes some of the key characteristics that will continue to help the city continue to distinguish itself as one of the most desired places in the SGV. Since incorporating in 1989, the city has balanced its small town charm with the challenges and pressures of urbanization in a major metropolitan area. It is continually rated one of the best cities to do business due to its business friendly practices, such as streamlined permitting process, no utility taxes, and low business fees. Furthermore, it has been nationally recognized by the follow- ing publications: • "Top 10 Towns for Families" by Family Circle Magazine; • "Best Places for Families" by Money Magazine; and • "50 Best Places to Raise Your Kids" by Business Week. Among the factors that contributed to the city receiving such recognition are its quality schools (two award-winning school districts), low crime rates (consistently ranked as one of the top three safest cities per capita in the SGV), cultural diversity, strong community spirit, parks and open space (over 360 acres), and higher than average family incomes. 37 Packet Pg. 132 Diamond Bar General Plan Update A city's quality of life characteristics can have significant real estate and economic development implications that should be leveraged in the General Plan Update. Public and private leadership needs to articulate a positive vision and spirit of optimism about what the city is becoming, build- ing from its assets and promoting the city as culturally diverse, safe, and livable for a broad range of current and prospective residents and businesses. 4.4 Growth Projections The following provides a summary overview of the population forecast utilized in this study. The information is provided by the Southern California Association of Governments (SCAG) and the Economic Development Division, and is utilized to evaluate the potential for various land uses under consideration in the General Plan Update. POPULATION Based on SCAG projections, the city's population will grow at a slower pace than experienced pri- or to incorporation. The city is projected to have a comparable growth rate to the county, so it will continue to make up 0.5 percent of the county's total population. In absolute terms, the city's population is projected to increase by approximately 6,800 people by 2040, which is approximate- ly 12 percent of the 2016 population base, or a 0.5 percent increase per year, as shown in Figure 4- 17.

Most long-term economic forecasts simply assume that present growth rates will continue at a set rate into the future. However, examining the employment projections, as shown in Figure 4-18, reveals several key trends: • In absolute terms, it is projected that the city will grow from approximately 16,500 jobs in 2016 to 19,300 jobs in 2040, resulting in a gain of 2,800 new jobs in the city. • It is projected that the city will increase its employment base at a growth rate similar to the county. • The projected job increases suggest the addition of around 100 to 120 net new jobs per year over the next 20 plus years, or a 0.6 percent annual increase.

Historic market trends have been examined to more accurately determine the potential for future land uses and associated development desired in the General Plan Update. Once again, trends for the city, region, and county have been analyzed for comparison purposes. Various recognized submarket areas definitions are used in the commercial real estate analysis. 5.1 Residential Demand for residential housing will be a byproduct of employment and population growth throughout the county. The following sections examine the regional market conditions for rental and for -sale residential properties as well as more localized information pertaining to residential potential in the city. It is important to note that this analysis does not attempt to replace the City's Housing Element. Rather, it is provided to include additional and updated market information. Housing Tenure and Vacancy The city has a significantly larger share of owner -occupied than renter -occupied housing in com- parison to both the region and county. Based on 2014 estimates, almost 80 percent of the housing is owner -occupied, as shown in Figure 5-1. Similar to other cities within the region, most of the city's housing stock is single-family for -sale properties, which is very different from the county where there is relatively equal split in terms of housing tenure. Housing vacancy characteristics do not show much variability from the region or county, where vacant properties typically make up five percent of the housing stock. 9 Submarket areas are specific geographic boundaries that serve to delineate a core group of buildings that are competi- tive with each other and constitute a generally accepted primary competitive set or peer group.

As shown in Table 5-1, about 70 percent of all housing stock in the city was built between 1970 and 2009, reflecting both strong population growth patterns during that time period along with the impacts of the Great Recession on housing demand and pricing, which has severely limited new development since 2010. While consistent with development trends in the region and county, the city has grown its housing stock at a slightly slower pace over the last dec- ade, as shown in Figure 5-2.

Following similar trends in the county, prices peaked in 2007 (Figure 5-4). However, after the rapid drop in median housing prices from 2008 to 2011, prices have been generally increasing. While the city's housing lost approximately 25 per- cent of its value during the recession, the county's larger disproportionate spike in prices during the peak of the housing market, before the Recession and the loss following the Recession, sug- gests the city's housing market is more resilient to larger macro -housing trends. For -Rent Pricing Since 2010, the median rental price (all units) has increased from approximately $1,570 to $1,820 per month in the city (Figure 5-5). This represents an absolute increase of $250 and a growth rate of around three percent. The city's median rental price was seven percent higher than the county in 2010. However, the median rental price in the county has grown tremendously over the last five years. In 2015, Zillow reported that the median rental price for all units in the county was approx- imately $2,200, which was 20 percent higher than the city. The increased rental rates in the county are a byproduct of increased demand for rental housing, which may reflect evolving market pref- erences or increased scrutiny on for -sale home mortgage lending standards. The city's rental housing stock prices have not kept pace with the county due to a lack of new development, which often drives market prices up through higher quality and amenities.

The development consists of 99 detached condominium units, and a 4.7 -acre neighborhood park, which will be dedicated to the City after completion. 5.2 Office Market potentials for office -related development within the city will be a function of the particu- lar attributes of the available land, adjacent land uses, and the regional economy and office mar- ket. Although the Los Angeles office market is comprised of many submarkets, each with poten- tially a distinct tenant profile, office space is highly substitutable, such that the potentials in any given market are determined by the strength of the regional office market. Thus, development activity, absorption, vacancy rates, and change in rental rates follow very similar patterns in most of the Los Angeles submarkets. Figure 5-6 illustrates the dramatic decline in office building construction in the Los Angeles office market following the recession of 1992 and 2009. For the 10 years from 1982 through 1991, The Los Angeles market averaged 14.1 million square feet of new office space completions annually. New construction essentially ceased during the mid-1990s, when it averaged deliveries of 1.3 mil- lion square feet annually as regional vacancy rates approached 20 percent. Similarly, leading up to the Great Recession, construction activity increased with average deliveries of 3.5 million per year from 2000 to 2009. During the post -recession recovery, the Los Angeles office market has aver- aged deliveries of approximately 1.6 million square feet per year, well below the 30 -year average of 5.8 million square feet per year. 45 Packet Pg. 140 Diamond Bar General Plan Update Figure 5-6: Historic Office Deliveries in Los Angeles Market (1 982 - 2016) 25.0 2 0. 0 15.0 V 10.0 c 0 Z 5.0 0.0 ��ti q�D� q�b q�� qq0 ggti qq� qqb cq 000 00'1. 0Z 00b 00� O\O O\� O\� O\b Deliveries —Average Source: CoStor 5.8 Table 5-2 tracks data for vacancy rates and average annual full-service (FS) rental rate for all three classes of office buildings, designated A, B, and C. The great majority of newly completed office space falls in the A category, although many new, low-rise suburban offices fall into category B. The C category is almost entirely comprised of older buildings that were initially of B quality. The data do not include functionally obsolete or vacated buildings. Since 2015, there have been declin- ing office vacancies that have placed upward pressure on asking rents. The SGV market area is inclusive of the Eastern SGV and Western SGV submarket areas, which are outlined in Figures 5-7 and 5-8, respectively. Table 5-3 summarizes the SGV submarket's con- text within the larger Los Angeles office market. The total rentable building area (RBA) accounts for approximately seven percent of the total supply. The current vacancy rate for all properties in the SGV submarket is around 8.4 percent, compared to the larger Los Angeles office market where vacancy hovers above 10 percent. However, given that the SGV submarket has less Class A properties, the average rent is lower ($24.48 per year) compared to the county. It is also worth noting that according to CoStar, there have only been four office buildings delivered since 2012. Even with the new deliveries, the overall RBA has only increased by approximately 164,000 square feet. 46 1.1 Packet Pg. 141 Figure 5-7: Eastern San Gabriel Valley Submarket | EaST LA County Outyling WAM 7 -,Jl 11 [a] Source: CoStor 20 14. ri, 7G 56H e I R 4iv e r 7' .7Mar ,,,71.A Afigeles �Z� Existing Conditions Report — Volume U.March ]0|7 Economic Review and Market Assessment T = 47 Diamond Bar General Plan Update Figure 5-8: Western San Gabriel Valley Submarket Source: CoStor 2014.

Current asking rent ranges from approximately $24.00 to $31.20 per square foot per year (Table 5-4). There is no known office development under construction at this time. However, in 2014 the City Council approved a mixed-use zoning on the former Honda dealership property (Honda Site), located to the north of the Orange freeway on the southwestern corner of Grand Avenue and Old Brea Can- yon Road.

As residential land prices have accelerated, demand for industrial space, associated rents and land prices have increased proportionately. The following figures (5-10, 5-11) and tables (5-5, 5-6, and 5-7) present data for the regional in- dustrial market. As shown in the following figure, the industrial market suffered a similar decline as the office market preceding the 1992 recession, but with a much more pronounced recovery in the late 1990s and a similar recovery following the Great Recession, with new construction com- prised predominantly of large-scale warehousing space.

Following similar trends to the Los Angeles industrial market, the Eastern SGV submarket, as shown in Fig- ure 5-7, has continued to lease vacant warehouse space, which has lowered the submarket's va- cancy from 5.8 to 2.0 percent. This tightening of available industrial space has put upward pres- sure on quoted asking rates that have increased by 31 percent. to A type of building designed to be versatile, which may be used in combination with office (corporate headquarters), research and development, quasi -retail sales, and including but not limited to industrial, warehouse, and distribution uses. A typical flex building will be one or two stories with at least half of the rentable area being used as office space. 53 Packet Pg. 148 1.1 Diamond Bar General Plan Update The following tables summarize the Eastern SGV's submarket's context within the larger Los An- geles industrial market. The total RBA accounts for only approximately 2.7 percent of the total supply. Current vacancy rates for all properties are around two percent, which is consistent with the larger Los Angeles industrial market. The lower desirability of the Eastern SGV submarket is seen in the lower quoted asking rents for warehouse and flex properties. However, the submar- ket's low vacancy rate suggests that it is able to compete with other submarkets where warehouse space is more expensive on a per square foot basis. The city's available industrial space inventory is concentrated primarily along Brea Canyon Road, north of Lycoming Avenue (Figure 5-11). The city currently estimates that there is approximately 19,000 square feet of industrial space available. Current asking rent for modified gross leases ranges from approximately $10.80 to $21.60 per square foot on a yearly basis. There is no known industrial development under construction at this time.

While a significant part of leisure and hospitality activity is associated with tourism, many of these jobs serve the local population and business travelers. The PKF East hotel submarket73, delineated in Figure 5-14, is used to eval- uate historic trends that will impact future development potential in the City. The metrics used to measure the health of the lodging market indicate a healthy and expanding industry. As shown in Table 5-12, the average hotel occupancy rate for the East in 2015 was an estimated 74.1 percent, which was up from 72.0 percent in 2014. The average daily rate (ADR) increased to $94 from $88 in 2014. The most critical measure to hoteliers is revenue per available room (RevPAR). In 2015, this was an estimated $70, a record high that was up 9.4 percent from 2014. 13 The Los Angeles East submarket consists primarily of hotels located along the Interstate 10 corridor stretching from Downtown to Pomona, but also Diamond Bar and other cities to the north and south. 63 Packet Pg. 158 1.1 Diamond Bar General Plan Update Table 5-12: Hotel Market Statistics Market/Year Market Occupancy Average Daily Rate Percent Change (Year Over Year) RevPAR Percent Change (Year Over Year) East 2016 Forecast 75.6% $99 5.4% $75 7.5% 2015 74.1% $94 6.3% $70 9.4% 2014 72.0% $88 5.3% $64 11.1% 2013 68.3% $84 5.2% $57 5.6% 2012 68.1% $80 5.9% $54 13.7% 2011 63.4% $75 $48 Growth Rate 5.7% 9.4% Los Angeles 2016 Forecast 80.9% $169 6.5% $136 8.3% 2015 79.6% $158 7.5% $126 8.7% 2014 78.7% $147 7.6% $116 10.4% 2013 76.6% $137 5.0% $105 6.9% 2012 75.3% $130 5.9% $98 11.2% 2011 71.7% $123 $88 Growth Rate 6.5% 9.1 Source: PKF Consulting USA 64 Packet Pg. 159 Figure 5-14: Los Angeles Hotel Submarkets 1pst Hills �yy a5tu ,_oke sab-ella o' Buttomvillow 4ildale Bakersfield Ricardo i amn nt Carrizo- Existing Conditions Report — Volume II, March 2017 Economic Review and Market Assessment Ridgacrast China Lala Fort trwln !b}idltary Novo!

Rising demand, together with a lack of new hotel construction, has helped improve lodging fundamentals to the point where a number of new hotel properties are finally in development throughout the Los Angeles region. This has been driven largely by constrained supply, as well as demand that has grown significantly in the last five years (Table 5-13).

For illustrative purposes, a summary evaluation of the composition of the existing hotel inventory is provided below. As portrayed in the Figure 5-15, most hotels are classified in the budget category (56 percent), with mid -price hotels representing an additional 26 percent of the inventory. Only three percent are classified as upscale properties. Economy properties, which are a tier higher than budget properties, make up the remaining 15 percent of the submarket hotel room supply. 66 Packet Pg. 161 Existing Conditions Report — Volume 11, March 2017 Economic Review and Market Assessment Figure 5- 15: Los Angeles East Submarket (201 6) Upscale 3% Midprice 26% Economy 15% Source: Smith Travel Research Budget 56% The city has a limited supply of hotel rooms (374 rooms) in three hotels (Figure 5-16). The hotels fall into the budget and economy price category14 with sampled room rates between approximate- ly $90 and $160 (Table 5-14). Given the weekday rack rate pricing, it appears that some of the ho- tels are more closely oriented to business related travel. While specific hotel performance is not available due to Smith Travel Research confidentiality requirements, transient occupancy tax (TOT) data reveals that hotels in the city have an Average Daily Rate (ADR) range that varies from $92 per night at 75 percent occupancy to $106 per night at 65 percent occupancy. This range suggests that city's hotel properties are of slightly higher quality than the average hotel in the East market. Following the dip during the Great Recession, taxable room sales grew from $5.7 million in 2010 to $9.4 million in 2015. This represents an increase of $3.7 million, or nearly $10,000 in per room revenue in the city. The nearly 65 percent growth in room revenue during the last five years boosted rooms sales above pre -recession levels, which is a positive signal for potential future de- velopment within the city (Figure 5-17). The Honda Site has been identified as a development opportunity for either a four -acre site to build a 180 -room mid -upscale business hotel with 48,200 square feet of office space, or a seven - acre site to build a 405 -room business suite hotel complex with up to 76,200 square feet of office space. 14 As defined by Smith Travel Research. 1.1 67 Packet Pg. 162 1.1 Diamond Bar General Plan Update Figure 5-I6: Diamond Bar Hotel Inventory (2016) s Note: Dots represent locations of hotels with numbers in squares representing multiple buildings.

These include, but are not limited to: • Honda Site; • Kmart Site; • Foremost Site; • Diamond Bar Golf Course; • Tres Hermanos Site; and • Metrolink Station Area. It is important to note that the City never had the "tools of redevelopment" that enabled other cities to obtain debt to finance many development projects in the region. Now, with the elimina- tion of redevelopment and associated tax increment financing, the City can use new tax incre- ment tools available to all cities (e.g. Enhanced Infrastructure Financing District) or other regula- tory controls (e.g. incentive based zoning) to more fairly compete for future development oppor- tunities. Some of these development opportunities were previously discussed, but a brief summary is in- cluded below. Honda Site In 2014, the City Council approved a mixed-use zoning on the former Honda dealership property located to the north of the Orange freeway on the southwestern corner of Grand Avenue and Old Brea Canyon Road. The Honda Site has been identified as a development opportunity for either a four -acre site to build a 180 -room mid -upscale business hotel with 48,200 square feet of office space, or a seven -acre site to build a 405 -room business suite hotel complex with up to 76,200 square feet of office space. The development could be positively impacted by the City of Industry's Business Center Development and future interchange upgrade opportunities to increase traffic flow and access to the Orange and Pomona freeways at Grand Avenue. Kmart Site Located on approximately eight acres, the Kmart site is situated at one of the gateways to the city along one of the most travelled thoroughfares. Pending approval, a reconfiguration of the site is proposed to accommodate space for new retail development in the city. 70 1.1 Packet Pg. 165 1.1 Existing Conditions Report — Volume 11, March 2017 Economic Review and Market Assessment Foremost Site In 2015, Foremost Companies acquired two adjacent shopping centers with over 120,000 square feet of leasable commercial space. The Ranch Center and Oak Tree Plaza encompass approxi- mately 10 acres on Diamond Bar Boulevard and have visibility and access to the Pomona and Or- ange freeways. The existing centers' tenants include restaurants, medical offices, a bowling alley, and various other neighborhood retailers. There is currently a mixed-use project in the conceptu- al design phase of approximately 148 residential condominium units that would entail demolish- ing the existing structures, except for a 12,000 -square -foot portion of one Ranch Center building that would be renovated and retained as a commercial use. Diamond Bar Golf Course The county -owned golf course property is located on over a one -mile long stretch of the freeway with visibility to an average of 350,000 vehicles per day. Based on the visibility and freeway expo- sure, as well as the adjacent ramps, the site represents an excellent commercial mixed-use rede- velopment opportunity. Furthermore, the aforementioned future interchange upgrade to the Or- ange and Pomona freeways would further enhance development opportunities. However, rede- velopment of the site is a controversial and polarizing issue. In addition to community concerns, any development plans would require the city to provide a matching property for the county elsewhere. Even given these concerns, considering the available land and potential development opportunities, the site is one of the best commercial sites in the region. Tres Hermanos Site The Tres Hermanos site includes 700 acres within the city limits that could accommodate future development. The large undeveloped area of Grand Avenue between the city and Chino Hills is currently held by the Successor Agency to the City of Industry's Redevelopment Agency. Given the wind -down of the legacy redevelopment agency, there is a possibility that the site will be placed on the market. Because the land is in the city and it retains control over the site through its General Plan and zoning regulations, the city could influence the potential land use planning for the site if it goes onto the open market. Alternatively, it could possibly serve as a site to relocate the Diamond Bar Golf Course if that location was redeveloped for a different use. Metrolink Station Area The City has identified an area for potential TOD near the Industry Station for Metrolink. The area is currently built out with a combination of civic, industrial, and office uses. The majority of the development is lower value "tilt -up" construction.15 However, given that a majority of the area is within a walkable quarter -mile radius to the Metrolink station, land values may support future redevelopment of these lower value industrial and office uses into higher -density residential de- velopment. Residential uses may be further enhanced as the area is within the Walnut Valley Uni- fied School District. 15 Refers to a construction technique where the building's walls are poured directly at the jobsite in large slabs of con- crete. These panels are then raised into position around the building's perimeter forming the exterior walls and is a cheaper form of development than other types of construction. 71 Packet Pg. 166 1.1 Diamond Bar General Plan Update This page intentionally left blank. 72 Packet Pg. 167 6 Long -Term Land Use Demand The following section provides long-term land use demand projections for the city and various submarkets throughout the region. Given that specific sites and development opportunities will generate various levels of demand, the following is intended to give broad parameters regarding the potential level of new development in the city. From this, development and land use opportu- nities can be evaluated to determine the required level of site capture (e.g. market demand) and if it is reasonable to plan for within the next 20 to 25 years. 6.1 Residential Residential projections are based on the current Housing Element and extended to 2040 using housing unit estimates from SCAG and the Department of Finance. The low range suggests the addition of 950 units, or 40 units per year over the next 24 years (Table 6-1). The total increase would suggest a growth rate similar to the city's growth between 1990 and 2016, where it added approximately 980 units, or just fewer than 40 new residential units per year. The high growth is projected by SCAG based on their latest regional transportation plan. This growth suggests an average of almost 140 new units a year, which would be very high given historic growth over the last two decades. The mid-range planning target takes an average of the high and low growth sce- narios. For planning proposes beyond the Housing Element horizon of 2021, a target growth sce- nario between the low and mid-range projection appears warranted unless the city desires creat- ing higher density mixed-use residential development at key development opportunities.

As noted, office development has slowed in recent years. Assuming the larger Los Angeles market adds office space at a rate projected to satisfy office -serving employ- ment in the region, then the submarket's "fair share" of the new development could reach approx- imately 2.2 million new square feet by 2040 in a mid -projection scenario (Table 6-2). This de- mand estimate makes assumptions such as: • New office jobs require 175 square feet of space per new job; and • Structural vacancy is 10 percent or, in other words, the market will continue building new office development as long as the vacancy rate does increase above that level.

For general planning purposes, the city could conservatively target to attract 12.5 percent of future office space in the East SGV, which is equivalent to the city's existing share of the East SGV development. This would suggest a range of approximately 240,000 to 300,000 new square feet of office construction. Other factors, such as the successful development of the Industry Business Center, could warrant higher capture rates if an office development strategy is desired by the city. 6.3 Industrial Overall, the East SGV industrial submarket represents approximately three percent of the total industrial space in the larger Los Angeles industrial market. As noted, industrial development has picked up since the Great Recession, but is only half of its historic average in deliveries. Assuming the larger Los Angele market adds industrial -serving jobs as projected, the submarket's "fair share" of new development could reach approximately 2.5 square feet of new industrial develop- ment in a mid -projection scenario (Table 6-3). This demand estimate makes assumptions such as: • New industrial jobs require 750 square feet of space per new job; and • Structural vacancy is 3 percent. While various development site opportunities might be able to accommodate future industrial development, the city has not historically had a strong industrial demand for leased properties. According to Costar, the city has only 33,000 square feet (0.1 percent of the East SGV rentable building area) of leasable industrial development. While other industrial development could be constructed, the lack of a true industrial business park area (beyond what has been identified at the TOD development site opportunity) limits future industrial development potential. For general planning purposes, the city could target to attract up to 7.5 percent of future industri- al space in the East SGV, which is equivalent to the city's existing share of the East SGV develop- ment. This would suggest a range of approximately 150,000 to 220,000 new square feet of indus- trial construction if properly clustered in an industrial business park setting with regional freeway access. Other factors, such as the previously identified success of the Industry Business Center, could warrant higher capture rates. However, given the scarcity of developable sites, other land uses would likely provide higher values to both developers and the city. 75 Packet Pg. 170 1.1 Diamond Bar General Plan Update Table 6-3: Regional Industrial Demand Estimate 2016 2020 2025 2030 2035 2040 Employment (jobs) Los Angeles County 4,239,783 4,332,440 4,451,1 14 4,573,039 4,698,304 4,827,000 Employment Industrial Employment 1,200,000 1,219,000 1,244,000 1,269,000 1,295,000 1,321,000 Cumulative Industrial - 19,000 44,000 69,000 95,000 121,000 Employment Office Space (Square Feet) Industrial Demand @ 750 SF - 15,200,000 35,200,000 55,200,000 76,000,000 96,800,000 per job Industrial Under Construction (4,983,658) - - - - - Industrial Preleased 1,266,107 (3,717,551) Net New Industrial Demand (3,717,551) 11,482,449 35,200,000 55,200,000 76,000,000 96,800,000 Occupancy in Equilibrium - 15,670,000 36,289,000 56,907,000 78,351,000 99,794,000 (97%) Industrial Demand Per Year - 3,918,000 4,032,000 4,065,000 4,124,000 4,158,000 East SGV Cumulative Capture Low @ 2.0% - 313,000 726,000 1,138,000 1,567,000 1,996,000 Mid @ 2.5% - 392,000 907,000 1,423,000 1,959,000 2,495,000 High @ 3.0% - 470,000 1,089,000 1,707,000 2,351,000 2,994,000 East SGV Annual Capture Low @ 2.0% - 78,000 81,000 81,000 82,000 83,000 Mid @ 2.5% - 98,000 101,000 102,000 103,000 104,000 High @ 3.0% - 118,000 121,000 122,000 124,000 125,000 Notes: I.

There are a number of competitive properties within the regional market, but limited competition with- in the city. Historically, the East hotel submarket has represented approximately 11 percent of the total Los Angeles hotel market. Assuming that the submarket attracts its fair share of long-term demand and there are no dramatic negative changes in occupancy in the market, approximately 5,800 to 7,400 new hotel rooms are expected by 2040. This demand estimate assumes that a 70 percent occupancy rate (market standard for investment) is held constant to establish the total supportable room nights in the submarket (Table 6-4).

Year 2020 - 2040 East submarket cumulative capture is based on assumed capture of County demand less 421 rooms currently under construction. Source: PKF Consulting, PFA Given that the city has a very low share of the submarket's overall room supply and that it does have development sites, such as the Honda Site, that would be attractive to hotel developers, the city's target share of submarket capture was increased from its existing share of approximately four to seven percent. For General Plan planning purposes, the city could conservatively target a range of 400 to 500 rooms of future demand. 77 Packet Pg. 172 1.1 Diamond Bar General Plan Update 6.5 Retail Unlike the projection methodology used for other land uses, which focuses on historic supply and demand estimates for capture, the retail demand model is based on a combination of existing spending assumed to be "leaking" outside the city as well as an assumed future capture of new residents and employee spending. To estimate the retail surplus/leakage for the city, it was assumed that the current estimated popu- lation of 57,000 persons has a per capita income of around $36,000. Potential sales (demand) from the city's residents were estimated using the gross disposable income, while taxable sales (supply) were estimated using information from ESRI. Finally, an adjustment of sales to supportable square feet was made, based on an estimate of current sales productivity levels assuming that resi- dents exhibit expenditure patterns consistent with observed ratios at the regional level.16 As shown in Table 6-5, it is assumed that the city is currently losing over one million square feet in supportable retail development. However, this analysis assumes 100 percent of resident capture, so the actual demand would be less than what is provided below. A conservative range of recap- ture is between 40 and 50 percent depending on the retail orientation and types of offerings (400,000 to 500,000 square feet).

Assuming that current household per capita income holds constant, based on population projections, the city could add up to 263,000 square feet by 2040 (Table 6-6). This would assume 100 percent capture of new spending and a retail productivi- ty of $345 per square feet. Again, given the high level of leakage, the opportunity for new retail space is high. Examining the region excluding Diamond Bar, there is a projected total 3.1 million square feet of demand. Once again, depending on the orientation of future retail, the new regional population represents additional new market for retail demand.

This analysis includes actual, adjusted, and adopted budgets for Fiscal Year (FY) 2012/13 through FY 2016/17.17 7.1 Introduction The analysis highlights fiscal challenges and opportunities that may affect future land use deci- sions made during the General Plan Update. This evaluation should be used to help City staff, the consultant team, and General Plan update stakeholders better understand the potential fiscal tradeoffs of land use choices. Specifically, the city desires to implement a responsible fiscal policy that ensures long-term financial sustainability as new development occurs over the next 20 to 25 years. General Plan land use alternatives will be defined in a future task of work and a detailed fiscal analysis will be prepared that quantifies the net fiscal impact of each alternative at build -out. A rise in the service population (employees and residential population) due to new development will impact the General Fund. The General Fund pays for most public services, including transporta- tion services, public works, police services, fire services, and parks, open space and recreational services, and is the sole focus of this analysis. 7.2 Existing Conditions As presented in the Figure 7-1, the City has maintained an average of $1.9 million more in re- sources than appropriations since FY 2012-13. However, during this time, the City has also aver- aged $1.4 million in revenue transferred in from other funds. Revenues have grown by 4.5 per- cent, while expenditures have grown by 4.0 percent over the time period. General Fund revenues are projected to be $26.1 million in FY 2016-17, which represents a 5.0 percent decrease from FY 2015-16 due to the projected amount of money transferred in from other funds. As a result, budg- eted appropriations have been reduced by 3.0 percent. In real dollars, the level of revenues adopt- ed by the city is equivalent to FY 2013-14. The narrowing gap between revenues and expenditures 17 To factor in the impact of inflation on revenues and expenses over this period, an inflation adjustment has been in- corporated and the results are presented both in nominal (i.e., current dollars, including the effects of inflation) and constant 2016 dollars. The analysis uses the Bureau of Labor Statistics' Consumer Price Index for the Los -Angeles - Riverside -Orange Region. Packet Pg. 176 Diamond Bar General Plan Update can also be examined by reviewing the revenues and expenditures indexed to FY 2012-13. With population growth relatively flat, the City will be faced with resource allocation dilemmas if Gen- eral Fund revenues decline at a rate faster than desired service levels in the future (Figure 7-2).

Total general fund revenues were approximately $27.1 million in FY 2014-15 in 2016 dollars. As shown in Figure 7-3, about 24 percent of General Fund revenues are from the Other Tax category, which includes sales tax, TOT, and franchise taxes. Approximately 17 percent of general fund rev- enues are derived from property taxes. State Subventions, which include Vehicle License Fee (VLF) property in -lieu taxes tied to the City's assessed value, contribute about 19 percent of reve- nue to the general fund in FY 2014-15, or about $5.3 million. Current Charges for Services repre- sent 22 percent of the revenue and include fees collected by the Planning, Engineering, and Recre- ation Departments to cover costs of providing services. Other Expenditures (four percent), Fund Balance Reserves (four percent), Use of Money and Property (four percent), and Transfer -in Oth- er Funds (six percent) represent the balance of the General Fund Resources (18 percent).

Other revenue sources that are likely to be less impacted by development have been excluded. This review is based on actual General Fund revenues from FY 2014-15 in nominal year values. Property Taxes Property taxes are derived from the assessed value of secured and unsecured property18 based on the City's General Fund share of the one percent base property tax rate. The city's annual assessed valuation is determined by the following factors: • The value of the prior year's "base" plus an added annual increment that includes a max- imum two percent statutory increase; • The added value through existing property sales; • The added value of new (construction) sales; and • The added or reduced value as a result of re -assessments. Changes in assessed valuation are capped by Proposition 13, which limits the annual increase to the lower of either a two percent increase or the California Consumer Price Index. When property is sold, the assessed value is determined by the sale price, which sets a new assessed value base for property tax collection purposes. Prior year uncollected taxes and interest, as well as penalties also comprise a small portion of the annual property taxes. Generally, municipalities collect between 10 and 15 percent of the one percent base property tax rate. In FY 2014-15, $4.4 million in prop- erty taxes were collected in the City. This represents 17 percent of all General Fund revenues. Property Transfer Taxes Property transfer taxes are a one-time tax upon the transfer (sale) of property based on a taxing formula of $1.10 per $1,000 in total property value. Property transfer taxes represent about one percent of total General Fund revenues. Sales Tax Sales tax revenues of approximately $2.7 million represent 10 percent of the General Fund Reve- nue. The City currently receives a one percent share of all taxable sales generated, which includes retail sales to customers as well as any taxable business -to -business sales. Transient Occupancy Tax These revenues are received on a monthly basis from the hotels in the city. The hotels are required to pay a 10 percent tax based on their room rental revenues. 18 Unsecured property refers to owned and leased business equipment rather than home ownership (secured). 84 1.1 Packet Pg. 179 1.1 Existing Conditions Report - Volume 11, March 2017 Economic Review and Market Assessment Franchise Tax Companies are granted special privileges for the continued use of public property, such as city streets. Such companies usually involve elements of monopoly and may require regulation. The Franchise Fees are the amounts required for the continued granting of these privileges. Franchises currently granted within the city are electric, gas, cable television, bus benches, and street sweep- ing. Sales Tax Compensation Fund Each county auditor is required to establish a Sales Tax Compensation Fund (Fund). The triple flip reimbursements are disbursed from this Fund in the amount set by the Department of Fi- nance. Local jurisdictions receive disbursements from the Fund in two installments, 50% prior to the end of January, and 50% prior to the end of May. However, the "triple -flip" ends in 2016,19 and the county will return the quarter -cent sales tax rev- enue to the City's General Fund. Initially, the effect of the end of the "triple -flip" will be neutral for the City. For taxable sales on and after January 1, 2016, the 0.25 percent will revert back to the original Bradley Burns tax rate. Counties and Cities will receive allocated payments directly from the Board of Equalization starting in March 2016 for 2016 Q1 taxable sales. As such, while this fund represented three percent of General Fund Revenue or $924,000 in Fiscal Year 2015-16, it has been reduced to zero for future planning. Vehicle License Fee (VLF) - Property Tax in Lieu The motor vehicle license fee rate was amended by the State in 2004, significantly reducing reve- nues to municipal governments.20 The actual motor vehicle in -lieu fee allocations were allocated to municipalities based on population growth. However, in order to make up for the loss in those revenues after the 2004 adjustment, the state compensates local governments by backfilling the gap with a portion of property tax revenues. This amount, now referred to as the VLF - Property in Lieu revenue, is based on proportional growth in assessed valuation of real property within a jurisdiction. The motor vehicle license fee has now been eliminated for FY 2016-2017. Fines & Forfeitures Several fines and fees are collected by the City. These include, but are not limited to, Vehicle Code Fines, Court Fines and Forfeitures, and Impound Fees. 19 In March 2004, California voters authorized the issuance of bonds to close the State's budget deficit. To guarantee bond repayment, the State established an excise tax equal to 0.25 percent of the sales price of property subject to the state's sales and use tax, and simultaneously lowered the Bradley -Burns Uniform Sales Tax one percent rate to 0.75 percent. The bonds are repaid from the 0.25 percent excise tax. The 0.25 percent reduction in local sales tax is recovered through a series of revenue swapping procedures. These exchanges are referred to as the "triple flip" and are not de- tailed herein. 20 The tax used to be two percent and then the rate was cut by 67.5 percent, which greatly impacted the revenue allocat- ed to the City by the State. 85 Packet Pg. 180 1.1 Diamond Bar General Plan Update Current Service Charges, Licenses, and Permits Several fees are associated with cost recovery for Community Development, Public Works, and Parks and Recreation. These include building fees, encroachment permit fees, planning and engi- neering fees, and recreation fees. KEY TRENDS In both real and nominal dollars, the General Fund revenues have increased over the last three years of actuals, as well as adjusted and adopted budgets for the last two years. With the continued recovery of the real estate market, property taxes and associated VLF - property tax in lieu reve- nues have increased by approximately 14 percent in real dollars. Sales Tax is projected to increase by 64 percent from FY 2012-13, which is a marked improvement, but as previously discussed, be- low pre -recession spending levels. On a per capita basis, revenue is expected to decline in FY2016- 17, which reverses the previous trend (Table 7-1).

Source: City of Diamond Bar Annual Budget 7.4 Appropriations OVERVIEW General Fund appropriations support various municipal services that represent the major source of discretionary funding for the City. Total general fund expenditures were approximately $24.4 million in FY 2014-15 in 2016 dollars. Consistent with other municipalities, about 25 percent of general fund costs fund Public Safety. General Fund transfers to other funds to support City activ- ities represent 18 percent of costs, while the Admin & Support, Parks and Recreation, and Public Works Departments represent 15 percent, 18 percent, and 10 percent, respectively. The other 14 percent of annual expenses were allocated in Community Development (eight percent) and Legis- lative (six percent) related activities (Figure 7-4). 87 Packet Pg. 182 Diamond Bar General Plan Update Figure 7-4: FY2014-15 Actual General Fund Appropriations (2016 Dollars) Legislative, $1,381,556, 6% Community Public Safety, Development, $6,062,670, 25% $1,886,750, 8% Public Works, $2,573,072, 10% Transfer -Out Parks and Other Funds, Recreation, $4,457,302, 18% $4,371,224, 18% Admin & Support, $3,654,290, 15% Source: City of Diamond Bar FY 2016 — 2017 Annual Budget and BLS EXPENDITURES The City contracts for many of its municipal services. These include police services, building and safety services, engineering, and road and landscape maintenance. The Los Angeles County Fire Department provides fire protection services. The county also provides library services through a Library District as well as sewer and sanitation services through a Sanitation District. Funds are collected through property tax bills and are dispersed by the County's Tax Collector Office. As such, all of these departments' associated costs are likely to be based on pro -rata increases for var- ious types of development. 88 1.1 Packet Pg. 183 Existing Conditions Report — Volume 11, March 2017 Economic Review and Market Assessment In regards to employment,21 the following departments consist of City staff: • Legislative (5.43 FTE's) • Administration and Support (12.45 FTE's) • Community Development (8.00 FTE's) • Parks and Recreation (30.14 FTE's) • Public Works (13.59 FTE's) Legislative The Legislative Department consists of the City Council, City Attorney, and City Manager/City Clerk. In general, these individuals help manage the City's growth and operations. It is unlikely that future development will significantly impact these annual expenditures. FY 2016-17 expendi- tures are estimated at $1.9 million for Legislative costs as follows: City Manager/City Clerk Office (79.4 percent), City Attorney (11.3 percent), and City Council (19.3 percent). Approximately $1.0 million of estimated expenditures are for personnel services (55 percent). Administration and Support Administration and Support consists of Finance, Human Resources, Safety Program, Information Systems, Civic Center, Public Information, and the Economic Development divisions. In general, these departments are responsible for day-to-day operations inclusive of managing finance, per- sonnel, technology, public information, and promotion and marketing in the City. FY 2016-17 expenditures are estimated at $3.9 million for Administration and Support as follows: Infor- mation Systems (28.8 percent), Finance (19.5 percent), Public Information (19.3 percent), Civic Center (13.1 percent), Human Resources (10.4 percent), Economic Development (8.5 percent), and Safety Program (0.4 percent). Approximately $1.9 million of estimated expenditures are for personnel (48 percent) and $60,000 for contract services (2 percent), which collectively represent 50 percent of projected costs. Community Development Community Development consists of the Planning, Building and Safety, and Neighborhood Im- provement divisions. In general, these departments are responsible for functions regarding plan- ning and development. FY 2016-17 expenditures are estimated at $1.7 million for Community Development as follows: Building and Safety (43.2 percent), Planning (38 percent), and Neigh- borhood Improvement (18.8 percent). Approximately $971,000 of estimated expenditures are for personnel (58 percent) and $633,000 for contract services (38 percent), which collectively repre- sent 96 percent of projected costs. 21 Employees defined as a City full-time employee (FTE). 1.1 89 Packet Pg. 184 Diamond Bar General Plan Update Parks and Recreation The Parks and Recreation Department administers the City's community recreation programs (e.g. youth and adult athletics, summer day camps, senior programs, etc.) and the operation of the Diamond Bar Center. FY 2016-17 expenditures are estimated at $3.3 million for Parks and Recre- ation as follows: Recreation (59.5 percent), Diamond Bar Center (35.2 percent), and Administra- tion (5.3 percent). Approximately $1.8 million of estimated expenditures are for personnel (55 percent) and $703,000 for contract services (22 percent), which collectively represent 77 percent of projected costs. Public Works Public Works consists of Administration, Engineering, Road Maintenance, Parks & Facilities Maintenance, and Landscape Maintenance. In general, these departments are responsible for maintaining transportation and infrastructure related activities. FY 2016-17 expenditures are es- timated at $4.9 million for Public Works as follows: Road Maintenance (36.1 percent), Parks & Facilities Maintenance (27.0 percent), Administration (17.6 percent), Engineering (13.8 percent), and Landscape Maintenance (5.5 percent). Approximately $1.4 million of estimated expenditures are for personnel (29 percent) and $2.3 million for contract services (48 percent), which collec- tively represent 77 percent of projected costs. KEY TRENDS In both real and nominal dollars, the General Fund expenditures increased from FY 2012-13 (ac- tuals) to FY 2015-16 (adjusted). However, in an effort to be diligent in controlling growth in ex- penses, the FY 2016-17 budget represents a decrease in costs in response to potentially declining revenues. General Fund revenues grew by 15 percent in constant 2016 dollars. Based on FY 2016- 17 cost estimates, the per capita City costs will have grown by 15 percent since FY 2012-13, which is slightly less than the projected growth of per capita City revenues (17 percent) over the same time period (Table 7-2). 90 1.1 Packet Pg. 185 1.1 Existing Conditions Report — Volume 11, March 2017 Economic Review and Market Assessment Table 7-2: General Fund Expenditures (Nominal Dollars) Source: City of Diamond Bar Annual Budget 7.5 Future Considerations The following section discusses the General Plan Update as it relates to key revenue sources and impacts on future land use decisions. IMPACT ON CHANGE OF AVAILABLE RESOURCES As noted, given the city has relatively slow population and employment growth, a large percent of its discretionary revenue comes from the assessed value of property (and associated taxes) and sales tax generated in the city.

Existing service level standards, as identified in the General Plan, have not been dis- cussed specifically, but rather the analysis focuses on the specific impacts of broad land use choic- es in the city. Residential (For -Sale and For -Rent) Typically, residential land uses have the highest revenue and service level cost potential. This is true because the land use generates key General Fund revenue items such as property tax, proper- ty transfer tax, sales tax, and increases the assessed value in the city that impacts the VLF - Prop- erty Tax in Lieu tax revenues. At the same time, they typically require the highest service levels (and associated costs) due to their relative impact on various City departments (specifically Police and Fire) compared to commercial development. Given that the city comprises predominately single-family detached housing, there is a question of whether compact, denser, multi -family (for -sale or for -rent) has a greater fiscal impact on the General Fund. The fiscal implication of compact development has been analyzed in municipalities throughout the country and will potentially need to be scrutinized while evaluating General Plan alternatives. Typically, the combination of density and or sales price needs to reach a certain threshold to make the residential development net positive to the City from the General Fund perspective. Office and Industrial The development of industrial and office space in the city will likely have a positive fiscal impact as typically jobs created by these land uses require fewer city services than residential develop- ment. The assessed value of commercial property generates property tax, property transfer tax, and VLF - Property Tax in Lieu tax revenues. In general, office uses generate higher property val- ues than industrial uses. Also, given that a relatively small portion of total employment is from city residents, new employees represent new opportunities to attract additional sales tax revenue both from consumers as well as new business -to -business related retail spending. Finally, there are various business related taxes that will provide additional revenue to the City. The costs associated with industrial and office space are relatively lower because calls for service are typically higher for residential and retail land uses. An increase in employment opportunities could also attract new residents to the city, which might help balance the job -to -housing ratio and have additional benefits from the transportation (and associated Public Works costs) perspective. Retail New retail development can have a positive impact on the General Fund largely through the gen- eration of sales tax. In the context of the city, the recapture of lost taxable sales from existing resi- dents and employees, as well as the capture of sales to new residents and employees, could pro- vide significant positive fiscal revenue. However, if there is not enough population or employ- ment growth to generate new retail demand equal to new supply, or if the new retail effectively represents a transfer to what is currently in the city, new retail development may cannibalize sales 93 Packet Pg. 188 Diamond Bar General Plan Update from existing retail establishments. This type of retail transfer will not generate new sales tax rev- enue. As such, careful consideration regarding the orientation of future retail development is war- ranted. Based on the retail demand analysis, it appears that future retail development could posi- tively impact the General Fund. Similar to office and industrial development, the city's relative service cost for commercial land is typically lower than residential uses. Hotel Hotel or other hospitality land uses typically have a significantly high net positive fiscal impact because, like other commercial uses, the service costs are lower than residential uses. Also, unlike other taxes (e.g. property and sales) where the City receives some portion of the tax rate, the City receives the full voter approved TOT rate. Open Space, Parks, and Public Facilities Open space, parks, and other public facilities will not generate property tax revenue. However, there is significant research suggesting that such public amenities can increase property values. Other Considerations Many of the costs associated with new development will be estimated on a pro -rata basis based on the number of new people and employees located in the city. There are many costs that might be recoverable through fees and are fiscally neutral. Other expenditures, including Legislative and much of Admin & Support departments, do not vary significantly with marginal increases related to new development due to their high level of fixed costs. In contrast, various city costs have service capacity thresholds, where there is a tipping point that will require a significant increase in costs at some point in time. An example would be a fire sta- tion. Currently there are three fire stations in the city with associated expenditures based on the service -level capacity and geographic reach of each station to meet desired response times. The fiscal impact analysis of the General Plan alternative will need to understand the point at which the stations would reach their operational capacity and a new station (e.g. new equipment, fire fighters, etc.) would be required. An understanding of each significant public facility service ca- pacity threshold will be considered as part of the preferred alternative selection process, as with- out consideration the costs allocated to future growth could be understated. 94 1.1 Packet Pg. 189 1.1 CITY OF DIAMOND BAR GENERAL PLAN UPDATE EXISTING CONDITIONS REPORT -VOLUME III Environmental Constraints and Opportunities;

The General Plan, which is required by law in the State of California, identifies current and future needs, sets policy, and provides a basis for land use decision-making by policymakers such as the Planning Commission and the City Council. Diamond Bar's current General Plan dates back to 1995 and is in need of an update as new opportunities, challenges, and approaches have emerged in recent years. The General Plan update process provides an exciting opportunity for Diamond Bar community members to share their vision for the city's future and provide input on the city's long-term goals and development opportunities. 1.2 Purpose and Organization of the Existing Conditions Report This Existing Conditions Report represents the first major step in the process of updating the General Plan for the City of Diamond Bar. This report provides spatial information on existing conditions in the city and its surrounding areas as well as an analysis of growth prospects and land demand. The Existing Conditions Report is used as a basis for: • Facilitating community input on planning issues and visions during community workshops; • Preparing alternative land use and transportation planning scenarios; • Formulating policies and implementation actions for the General Plan; and • Creating the environmental setting portion of the Environmental Impact Report for the General Plan. The focus is on resources, trends, and critical concerns to frame decision-making for the long-term physical development of the city. Much of the information, including that on land uses, natural resources, civic and transportation infrastructure, current development projects and potential development capacity, is presented with maps. The Existing Conditions Report is organized into three separate volumes. 1.1 Packet Pg. 196 1.1 Diamond Bar General Plan Update • Volume L Land Use, Community Character, and Design; and Mobility and Circulation • Volume H. Economic Review and Market Assessment • Volume III. Environmental Constraints and Opportunities; and Public Facilities, Services, and Utilities VOLUME III: ENVIRONMENTAL CONSTRAINTS AND OPPORTUNITIES; AND PUBLIC FACILITIES, SERVICES, AND UTILITIES This is the third of three volumes of the Existing Conditions Report. An overview of the organization and contents of Volume III is provided below. 1. Introduction and Overview. This chapter provides an overview of the General Plan Update, as well as the purpose and organization of the Existing Conditions Report. It also distills the baseline research and analysis of Volume III of the Existing Conditions Report into planning considerations that should be addressed as the General Plan update process moves forward. 2. Environmental Constraints and Opportunities. This chapter discusses the General Plan Planning Area's environmental resources and potential constraints to development, including air quality; biological resources; hydrology, flooding, fire hazards, and water quality; cultural and historic resources; other hazards and hazardous materials; geology and soils; greenhouse gases; and noise. 3. Public Facilities, Services, and Utilities. This chapter discusses the current condition of the General Plan Planning Area's parks, recreation, and open space; and public schools and facilities; as well as Diamond Bar's systems of potable water, sewer and wastewater treatment, solid waste collection, and stormwater and flood control. 1.3 Key Findings and Planning Considerations The Existing Conditions Report serves to extract the most relevant information from the extensive baseline research efforts, providing a framework for further analysis and discussion with the community. The most significant findings from topics covered in Volume III are summarized below. 2 • Diamond Bar, similar to other communities in the San Gabriel Valley, faces significant environmental challenges regarding air quality, wildfire hazards, and water resources. While the region has steadily improved its air quality over the years, Diamond Bar must be very mindful of associated public health impacts. Not only is Diamond Bar located at the crossroads of two major freeways that are major sources of air pollution, but the city is also subject to pollutants and other hazards from wildfires. The city is one of many Southern California communities that relies almost exclusively on imported water, and drought conditions will continue to strain this collective water source. These threats to the city's air quality and water supply are compounded by the effects of climate change. The General Plan update should consider mechanisms that will reduce air pollution and mitigate its impacts, and should also consider the water usage of different land use types. Packet Pg. 197 1.1 Existing Conditions Report — Volume III, January 2017 Environmental Constraints and Opportunities; Public Facilities, Services, and Utilities • Climate change is an imminent threat to quality of life in Diamond Bar. The City should consider strategies to mitigate climate change and help industry and residents adapt to its effects. The effects of climate change in the San Gabriel Valley include increased temperatures, reduced precipitation, flooding, and reduced water supply. Diamond Bar could consider policies and strategies to support business operations and residents in becoming more resilient to the effects of climate change. • The amount of parkland is inadequate to serve the needs of the resident population. The current ratio of developed park acres per 1,000 residents is 1.30, far behind the goal of 5.0 set forth in the 1995 General Plan. It falls below this threshold even when factoring in planned and undeveloped parks. As the city's population grows further over the next 20 years, ensuring creation of adequate parkland to meet the need will be an important priority. Diamond Bar possesses high -performing schools that are the pride of the community and attract many families, though funding and legislative challenges threaten their stability. While good schools are one of the city's greatest assets, the potential end of the District of Choice program would have significant impacts in Diamond Bar, including Walnut Valley USD's potential loss of over 3,000 students. Pomona USD's schools within Diamond Bar perform well relative to the District and elsewhere, though low enrollment numbers threaten the ability for all schools to remain open. In addition, the State's school funding formula results in Diamond Bar schools having some of the lowest funding per student in California. • Community groups for the young and for seniors lack dedicated facilities. The city's population is aging, though there is no senior center to serve the growing senior population. The Diamond Bar Center hosts meetings from several senior clubs in the city, though representatives from senior groups have expressed desire for a dedicated space that can be accessed at all times, with activities and meal service. Potential sites include the space near the Diamond Bar Center that was once considered for dedication to the library before it moved to City Hall, or a repurposing of a school site. Additionally, while the city's schools are strong, there is no youth/teen center to serve groups like DB4Youth. • The current status of sewer and storm drain facilities in Diamond Bar is not fully understood. The City and County are currently negotiating ownership and maintenance responsibilities for trunk sewers and wastewater treatment services within the city, as well as the local storm drain system. A full accounting of existing and future deficiencies within those systems will not be possible until such negotiations are settled. Packet Pg. 198 Diamond Bar General Plan Update This page intentionally left blank. 1.1 Packet Pg. 199 1.1 2 Environmental Constraints and Opportunities 2.1 Air Quality and Greenhouse Gases The City of Diamond Bar is located within the South Coast Air Basin (Air Basin), which consists of the entire Orange and Los Angeles Counties, and the western, non -desert portions of San Bernardino and Riverside Counties, in addition to the San Gorgonio Pass area in Riverside County. The South Coast Air Quality Management District (SCAQMD) is the air pollution control agency for the Air Basin, and it adopts air quality management plans (AQMP) to achieve air quality standards in the Air Basin. The Air Basin is topographically bounded by the Pacific Ocean to the west and the San Gabriel, San Bernardino, and San Jacinto Mountains to the north and east. The terrain and geographical location determine the distinctive climate of the Air Basin, as it is a coastal plain with connecting broad valleys and low hills. The Air Basin lies in the semi-permanent high-pressure zone of the eastern Pacific Ocean, which usually provides a mild climatological pattern, interrupted by periods of hot temperatures, winter storms, or Santa Ana winds. The extent and severity of pollutant concentrations in the Air Basin is a function of the area's natural physical characteristics (weather and topography) and man-made influences (development patterns and lifestyle). Factors such as wind, sunlight, temperature, humidity, rainfall, and topography all affect the accumulation and dispersion of pollutants throughout the Air Basin, making it an area of high pollution potential. The Air Basin's meteorological conditions, in combination with regional topography, are conducive to the formation and retention of ozone, which is a secondary pollutant that forms through photochemical reactions in the atmosphere. Thus, the greatest air pollution impacts throughout the Air Basin typically occur from June through September, when ozone concentrations are highest. This condition is generally attributed to the emissions occurring in the Air Basin, light winds, and shallow vertical atmospheric mixing. These factors reduce the potential for pollutant dispersion causing elevated air pollutant levels. Pollutant concentrations in the Air Basin vary with location, season, and time of day. Concentrations of ozone, for example, tend to be lower along the coast, higher in the near inland valleys, and lower in the far inland areas of the Air Basin and adjacent desert. Packet Pg. 200 1.1 Diamond Bar General Plan Update CRITERIA POLLUTANTS Certain air pollutants have been designated as "criteria" air pollutants because they are common and widely distributed, and are known to have adverse human health effects and/or cause adverse impacts to the environment either directly or through reactions with other pollutants. Criteria air pollutants are indicators of ambient air quality and include: ozone (03), carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), respirable or breathable particulate matter with an aerodynamic diameter of 10 micrometers or less (PM,o), fine particulate matter with an aerodynamic diameter of 2.5 micrometers or less (PM2.5), and lead. The criteria pollutants are regulated by the United States Environmental Protection Agency (EPA) at the national level and by the California Air Resources Board (CARB) at the State level, and are subject to respective ambient air quality standards adopted by EPA and CARB. The Air Basin is an area designated as non -attainment because it does not currently meet National Ambient Air Quality Standards (NAAQS) for certain pollutants regulated under the Clean Air Act. The Clean Air Act set certain deadlines for meeting the NAAQS within the Air Basin including the following: (1) 1 -hour 03 by the year 2010; (2) 8 -hour 03 by the year 2024;' (3) PM,o by the year 2006; and (4) PM2.5 by the year 2015. Nonattainment designations are categorized into seven levels of severity: (1) basic, (2) marginal, (3) moderate, (4) serious, (5) severe -15, (6) severe -17, and (7) extreme? On June 11, 2007, the EPA reclassified the Air Basin as a federal "attainment" area for CO and approved the CO maintenance plan for the Air Basin.3 The Air Basin previously exceeded the NAAQS for PM,o, but has met the NAAQS at all monitoring stations and the EPA approved the request for re -designation to attainment effective July 26, 2013.4 The Air Basin does not meet the NAAQS for 03 and PM2.5 and is classified as being in non - attainment for these pollutants. The Los Angeles County portion of the Air Basin is designated as non -attainment for lead; however, this is due to localized emissions from two lead -acid battery recycling facilities located in the City of Vernon and the City of Industry, which are the only two lead -acid battery recycling facilities in Los Angeles County.' The attainment status of the Los Angeles County portion of the Air Basin with respect to the NAAQS and California Ambient Air Quality Standards (CAAQS) is summarized in Table 2-1. The 8 -hour ozone attainment deadline for the 1997 standard of 80 parts per billion is 2024. The 8 -hour ozone attainment deadline for the 2008 standard of 75 parts per billion is 2032. 2 The "-15" and "-17" designations reflect the number of years within which attainment must be achieved. 3 "Approval and Promulgation of Implementation Plans and Designation of Areas for Air Quality Planning Purposes: California, Final Rule."

GREENHOUSE GASES This section evaluates greenhouse gas (GHG) emissions and impacts to global climate change. Climate change refers to a change in global and regional weather patterns, particularly the change apparent from the mid-to-late 20th century to present day. GHGs are those compounds in the Earth's atmosphere that play a critical role in determining temperature near the Earth's surface. More specifically, these gases allow high -frequency shortwave solar radiation to enter the Earth's atmosphere, but retain some of the low frequency infrared energy which is radiated back from the Earth towards space, resulting in a warming of the atmosphere. GHGs result from human activities associated with industrial manufacturing, vehicle emissions, waste, and the use of electricity generated from fossil fuels. In California, about 40 percent of greenhouse gas emissions come from the transportation sector.The California Governor's Office of Planning and Research 2015 Draft General Plan Guidelines focus on how general plans can both help reduce greenhouse gas emissions and strengthen resiliency to climate change impacts. For example, the proximity between housing and job centers and the design of transportation networks determines the distance needed to travel between destinations and the transportation mode choices available. These factors directly influence the amount of greenhouse gas emissions from the 7 Packet Pg. 202 Diamond Bar General Plan Update transportation sector. As part of the General Plan update process and preparation of the accompanying Environmental Impact Report, a baseline greenhouse gas emissions inventory of the Planning Area will be prepared. Mitigation In 2006, the California State Legislature adopted AB 32 (codified in the California HSC, Division 25.5 — California Global Warming Solutions Act of 2006), which focuses on reducing GHG emissions in California to 1990 levels by 2020. HSC Division 25.5 defines GHGs as CO2, CH4, N2O, HFCs, PFCs, and SF6 and represents the first enforceable statewide program to limit emissions of these GHGs from all major industries with penalties for noncompliance. The law further requires that reduction measures be technologically feasible and cost effective. Under HSC Division 25.5, CARB has the primary responsibility for reducing GHG emissions. CARB is required to adopt rules and regulations directing state actions that would achieve GHG emissions reductions equivalent to 1990 statewide levels by 2020. In 2016, the California State Legislature adopted Senate Bill 32 (SB 32) and its companion bill AB 197, which was signed by the Governor. SB 32 and AB 197 amends HSC Division 25.5 and establishes a new climate pollution reduction target of 40 percent below 1990 levels by 2030 and includes provisions to ensure the benefits of state climate policies reach into disadvantaged communities. CARB is in the process of preparing the second update to the Scoping Plan to reflect the 2030 target established in Executive Order B-30-15 and SB 32. To help reach these goals, the State adopted the Sustainable Communities and Climate Protection Act (SB 375, 2008), which requires each major region of the state to adopt a Sustainable Communities Strategy (SCS) as part of their Regional Transportation Plan (RTP). The SCS integrates land use, transportation, and housing planning to improve proximity and connectivity of jobs and housing to reduce greenhouse gas emissions from passenger vehicles and to meet State - mandated regional greenhouse gas emissions reduction targets. Under SB 375, which establishes mechanisms for the development of regional targets for reducing passenger vehicle greenhouse gas emissions, reduction targets must be incorporated within that region's Regional Transportation Plan (RTP), which is used for long-term transportation planning, in a Sustainable Communities Strategy (SCS). On April 7, 2016, the Southern California Association of Governments (SCAG) adopted the 2016-2040 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS), which is an update to the previous 2012-2035 RTP/SCS.6 The RTP/SCS successfully achieves and exceeds the GHG emission -reduction targets set by CARB by demonstrating an 8 percent reduction by 2020 and 18 percent reduction by 2035 compared to the 2005 level on a per capita basis.' Air emissions for the Air Basin are regulated by the SCAQMD, which is responsible for promoting and improving the air quality of the Air Basin though air quality monitoring, evaluation, education, implementation of control measures to reduce emissions from stationary sources, permitting and 6 Southern California Association of Governments, 2016-2040 RTP/SCS, http://scagrtpscs.net/Documents/2016/final/f2016RTPSCS.

After AB 32 was passed, the SCAQMD formed a Climate Change Committee along with a Greenhouse Gases CEQA Significance Thresholds Working Group and the SoCal Climate Solutions Exchange Technical Advisory Group. On September 5, 2008, the SCAQMD Board approved the SCAQMD Climate Change Policy, which outlines actions the District will take to assist businesses and local governments in implementing climate change measures, decrease the agency's carbon emissions, and provide information to the public regarding climate change. On December 5, 2008, the SCAQMD adopted an annual screening level threshold of 10,000 metric tons Of CO2 equivalent (MTCO2e) for industrial projects for which the SCAQMD is the Lead Agency or has discretionary approval! The SCAQMD, in accordance with CEQA Guidelines Section 15064.7, adopted its annual threshold for industrial sources under a public review process as part of stakeholder working group meetings that were open to the public and based on substantial evidence. The intent of the threshold is to capture 90 percent of total emissions from all new or modified industrial and stationary source sector projects subject to a CEQA analysis where the SCAQMD is the lead agency. Data collected by the SCAQMD from its Annual Emissions Reporting (AER) Program indicates that a 90 percent capture rate would cover a substantial portion of future project emissions and would exclude small projects that will in aggregate contribute a relatively small fraction of the cumulative statewide GHG emissions.' The SCAQMD estimates that these small projects will in aggregate contribute less than one percent of the future 2050 statewide GHG emissions target. The SCAQMD has not adopted a significance threshold applicable to residential and commercial land use development plans, such as a local jurisdiction's General Plan. The SCAQMD Working Group proposed a plan -level efficiency -based performance standard for land use development projects. The standard was developed by dividing the 2020 statewide GHG reduction target by the sum of the total statewide service population (population and employment). The result was a plan - level performance standard of 6.6 MTCO2e per year per service population. The proposed threshold was developed using a similar methodology as the Bay Area Air Quality Management District (BAAQMD), which also developed a plan -level performance standard of 6.6 MTCO2e per year per service population to evaluate the significance of plan -level land use development projects in its jurisdiction. The City of Diamond Bar has not yet adopted a sustainability plan or GHG reduction plan. However, the City has adopted the California Green Building Standards (CALGreen) Code. The purpose of the CALGreen Code is to "improve public health, safety and general welfare by enhancing the design and construction of buildings through the use of building concepts having a positive environmental impact and encouraging sustainable construction practices in the following categories: (1) Planning and design; (2) Energy efficiency; (3) Water efficiency and conservation; 8 South Coast Air Quality Management District, Board Meeting, Agenda No. 31, Interim CEQA GHG Significance Threshold for Stationary Sources, Rules and Plans, December 5, 2008.

Accessed October 2016. 9 Ibid. 9 Packet Pg. 204 Diamond Bar General Plan Update (4) Material conservation and resource efficiency; and (5) Environmental air quality."10 The City's Building Code was amended for consistency with the CalGreen Building Code. These measures would apply to all new buildings (residential and non-residential) and would increase energy efficiency and reduce waste. In order to comply with the 2016-2040 RTP/SCS, Diamond Bar and other communities across Southern California will be required to adopt land use and transportation policies that reduce dependence on car travel and increase accessibility and mobility through low -carbon transportation modes such as public transit, walking, and biking. For example, land use policies that encourage compact, mixed-use, infill development with appropriate parking management allow for residents to shop, get to work, or reach other destinations without travelling long distances by car. Land use policies can also conserve water use, as residents of larger lots often use more water per capita and require more infrastructure to supply the water. Along with adopting the CALGreen Code and more sustainable land use and transportation policies, municipalities can take other actions to mitigate climate change. Cities can encourage energy efficiency in the generation of renewable energy; reduce and manage waste efficiently to reduce emissions from the transport of goods and decomposition of organic materials in landfills; encourage local and sustainable food options that are more energy efficient to produce and transport; and conserve water which is energy -intensive to transport and heat. 2.2 Biological Resources The Planning Area is located in southeast Los Angeles County within the Puente -Chino Hills Wildlife Corridor. Topographically, much of Diamond Bar exhibits steep to gently rolling slopes and ridges with intervening narrow canyons. Along its southeastern boundary, the Planning Area includes portions of the Tonner Canyon watershed, which is a tributary to Brea Canyon just south of the city's southern limits. The majority of land within the Planning Area is developed, primarily with residential communities, businesses, schools, roads, and small parks. Woodland, shrubland, and grassland make up the majority of the vegetation communities within the city limits. However, the city's sphere of influence includes vacant land largely dominated by natural and naturalized plant communities. GENERAL LAND COVER IN THE PLANNING AREA The city is approximately 9,526 acres in size and its SOI is an additional approximately 3,513 acres, all of which is to the south of the city limits. Although primarily developed as a residential community, Venturan coastal sage scrub, California walnut woodland, and non-native grassland have a large presence within the rolling hill terrain that occurs within the Planning Area. California walnut coast live oak woodland is commonly found on the north -facing slopes, while coastal sage scrub is commonly found on the south -facing slopes of the hills throughout the Planning Area. 10 California Building Standards Commission, 2016 California Green Building Standards Code, (2016). 1.1 Packet Pg. 205 Existing Conditions Report — Volume 111, January 2017 Environmental Constraints and Opportunities; Public Facilities, Services, and Utilities Table 2-2 identifies the vegetation communities and land cover types within the Planning Area, and their locations are mapped in Figure 2-1.

It is composed of low, soft -woody subshrubs on dry slopes below 3,000 feet. The dominant characteristic species found in VCSS within the city include California sagebrush (Artemisia californica), California buckwheat (Eriogonum fasciculatum), and black and white sage (Salvia melifera and Salvia apiana). A dominance of California buckwheat is present within some of the VCSS communities, while California sagebrush is the dominant species in other areas. Other species present within this vegetation community include lemonadeberry (Rhus integrifolia), brittlebush (Encelia farinosa), and coastal prickly pear (Opuntia littoralis). The understory is dominated by non-native grasses such as brome (Bromus spp.) and wild oats (Avena spp.). Where non-native grasses dominate the VCSS communities at greater than 50 percent, the community is categorized as disturbed VCSS. VCSS commonly occurs on south -facing slopes throughout the Planning Area. Non -Native Grassland (42200)12 Non-native grassland consists of dense to sparse annual grasses less than three feet high. Within the city, this community is dominated by bromes, oats, tocalote (Centaurea melitensis), Russian thistle (Salsola tragus), Mediterranean mustard (Hirschfeldia incana), and telegraph weed (Heterotheca grandiflora). Other broadleaf weeds may also be present. Non-native grassland is largely located in the northeastern corner of the city, due to a historic presence of agricultural uses, as well as in small parcels throughout the city, often in areas that have been cleared for fire control. Sycamore Alluvial Woodland (62100)13 Southern alluvial woodland is located along braided channels of intermittent streams, consisting of open to moderately closed winter -deciduous trees and dominated by western sycamore (Platanus racemosa). Blue elderberry (Sambucus nigra) is also a characteristic species. Within the city, this habitat is composed largely of western sycamore, with blue elderberry and coast live oak (Quercus agrifolia) interspersed throughout. A small patch of sycamore alluvial woodland is located in the northwest corner of the city. 11 Crosswalk From Holland Vegetation types to the Manual of California Vegetation 2nd Edition (Sawyer et al. 2009): California Coastal Scrub. 12 Crosswalk From Holland Vegetation types to the Manual of California Vegetation 2nd Edition (Sawyer et al. 2009): Mediterranean California Naturalized Annual and Perennial Grassland. 13 Crosswalk From Holland Vegetation types to the Manual of California Vegetation 2nd Edition (Sawyer et al. 2009): Platanus racemosa (Southern sycamore woodlands) Alliance. 12 1.1 Packet Pg. 207 Figure 2-1: Habitats Walnut Metrolink Station LYCOMING ST 2 �� 90 GENERALPLAN City of Diam T NG H LAND VLY RD /yam/ CHF `Q°SS�NG RD 6p:"}� \. ryOA�\I Pomona CRO\N \. k,. ,P ?GIENPO ` 1 p DEEpPAH aD I MN0 DP /..

Within city boundaries, this community consists mainly of arroyo willow (Salix lasiolepis). Much of this habitat within the city is between 6 and 15 feet in height and varies in density, from relatively open to impenetrable. Southern willow scrub is located in a single patch along a drainage on the central portion of the eastern border of the city. Coast Live Oak Woodland (71 160)15 Coast live oak woodland is dominated solely by coast live oak trees, which can reach approximately 30 to 75 feet in height, and occur generally in shaded ravines on north -facing slopes. This community often has limited shrub cover with an understory of ripgut grass (Bromus diandrus). Within the city, the dominate plant species is coast live oak, with limited shrubs such as toyon (Heteromeles arbutifolia) and laurel sumac (Malosma laurina) and an understory of mixed grasses, predominately brome and oat. Coast live oak woodland is located in the northeastern region of the city, generally on north -facing slopes. California Walnut Woodland (71210)16 California walnut woodland is similar to coast live oak woodland but is dominated by Southern California black walnut (Juglans californica); however, coast live oak is a common species of this habitat. Within the city, the dominance of coast live oak varies throughout this habitat, but is largely present throughout. Other species present within this habitat include toyon, laurel sumac, blue elderberry, and an understory of non-native grasses such as brome and oat. California walnut woodland is dispersed throughout much of the city, generally occurring on north -facing slopes. Mixed Plant Communities In cases where two or more vegetation types are highly intermixed, they have been mapped as one mixed plant community. Within the study area these occur as: 1) California walnut woodland/coast live oak woodland, where California walnut trees and coast live oak trees grow in proximity with one another and often have overlapping canopies; and 2) California walnut woodland/coast live oak woodland/Venturan coastal sage scrub, where California walnuts and coast live oaks grow together in small copses with Venturan coastal sage scrub being found in between. 14 Crosswalk From Holland Vegetation types to the Manual of California Vegetation 2"d Edition (Sawyer et al. 2009): Southwestern North American Riparian, Flooded and Swamp Forest. 15 Crosswalk From Holland Vegetation types to the Manual of California Vegetation 2"d Edition (Sawyer et al. 2009): Quercus agrifolia (Coast live oak woodland) Alliance. 16 Crosswalk From Holland Vegetation types to the Manual of California Vegetation 2"d Edition (Sawyer et al. 2009): Junglans Californica Alliance. 15 Packet Pg. 210 Diamond Bar General Plan Update Other Land Cover Types Non -Native Riparian17 Non-native riparian consists of densely vegetated riparian thickets heavily dominated by invasive plant species. Within the city, this community consists largely of Mexican fan palm (Washingtonia robusta), Brazilian pepper tree (Schinus terebinthifolius), and eucalyptus (Eucalyptus sp.). Tree of heaven (Ailanthus altissima) and ornamental pines (Pinus sp.) also occur within this community. There is some presence of arroyo willow and coast live oak, but natives such as these make up less than 25 percent of the vegetation within this community. Non-native riparian habitat is located in a single patch that runs along the south side of State Route 60 in the northern portion of the city. Developed18 Developed/urban areas have been physically altered to the point where they can no longer support native vegetation. The land cover type includes areas with permanent or semi-permanent structures, pavement or other hardscape, and landscaped areas that require irrigation. Developed land constitutes nearly two-thirds of the land within the city and is present throughout the city. It includes businesses, residences, schools, parks, highways and other roads, sidewalks, and irrigated landscapes. Within the areas called out as developed habitat, there may be some oak, walnut trees, or other small pockets of native habit. Disturbed' Disturbed areas have been physically altered by previous human activity and are no longer able to support a recognizable native or naturalized vegetation association. The soil is often highly compacted or frequently disturbed. Disturbed habitat within the city has shown evidence of discing or high compaction. Only two small portions within the northern region of city were mapped as disturbed; both areas are along roads and adjacent to businesses. Non -Native Woodland19 Non-native woodland typically consists of planted, non-native trees, often characterized by eucalyptus. Within the city, non-native woodland consists of Brazilian pepper trees, ornamental pines, eucalyptus, and acacia (Acacia sp.), among others. This habitat is located in the southern portion of the city. COMMON WILDLIFE The plant communities discussed above provide wildlife habitat. While a few wildlife species are entirely dependent on a single natural community or on only a few of these communities, other wildlife species use most or all of the entire mosaic of all the plant communities within the city and adjoining areas. Other species are highly tolerant of urban and suburban environments and 17 Crosswalk From Holland Vegetation types to the Manual of California Vegetation 2"d Edition (Sawyer et al. 2009): Introduced North American Mediterranean woodland and forest. 18 Crosswalk From Holland Vegetation types to the Manual of California Vegetation 2"d Edition (Sawyer et al. 2009): No applicable crosswalk. 19 Crosswalk From Holland Vegetation types to the Manual of California Vegetation 2"d Edition (Sawyer et al. 2009): Introduced North American Mediterranean woodland and forest. 16 1.1 Packet Pg. 211 1.1 Existing Conditions Report — Volume III, January 2017 Environmental Constraints and Opportunities; Public Facilities, Services, and Utilities proliferate within developed areas. Following is a discussion of wildlife populations within the city, segregated by taxonomic group. WILDLIFE MOVEMENT Wildlife movement corridors are generally defined as connections between blocks of habitat that allow for physical movement and genetic exchange between otherwise isolated animal populations. Movement corridors may be local, such as between foraging and nesting or denning areas, or they may be regional in nature, allowing animals to access alternative territories as fluctuating dispersal pressures dictate. In the absence of wildlife corridors, various studies have concluded that some wildlife species, especially the larger and more mobile mammals, will not likely persist over time in fragmented or isolated habitat areas because such conditions preclude the infusion of new individuals and genetic information into isolated populations20. Tonner Canyon, to the southeast of the city, is an important part of a regional wildlife movement corridor that provides a linkage between the Cleveland National Forest in the Santa Ana Mountains through the Chino Hills and the Puente Hills. Its importance is due not only to its being largely undeveloped, but also its funneling effect on wildlife movement to the only natural undercrossing of State Route 57. The corridor, known as the Puente -Chino Hills Wildlife Corridor, has been the subject of a number of studies.21 22 23 24 25 26 27 28 29 The results of these studies were summarized by Spencer, along with his own analysis.30 The Puente -Chino Hills Wildlife Corridor has also been the focus of the Wildlife Corridor Conservation Authority, a public and private coalition, and the Puente Hills Landfill Native Habitat Preservation Authority that obtain funds to purchase land for the corridor. 20 England.

Most notably, the city's SOI encompasses the Firestone Boy Scout Reservation (approximately 800 acres), land owned by the City of Industry (approximately 2,125 acres), and land owned by Aera Energy (approximately 600 acres) that are generally not being used for livestock grazing or oil production. SPECIAL STATUS SPECIES AND HABITATS The city boundaries contain three plant communities considered sensitive by the California Department of Fish and Wildlife (CDFW) due to their scarcity and/or because they support special status plant and wildlife species. These communities are considered highly imperiled communities by the CDFW, indicating that they are declining in acreage throughout their range due to land use changes. These communities are described previously and include Venturan coastal sage scrub, southern willow scrub, and California walnut woodland. Sensitive plants include those listed, or candidates for listing, by the U.S. Fish and Wildlife Service (USFWS) and CDFW, and species considered sensitive by the California Native Plant Society (CNPS), particularly Lists 1A, 1B, and 2. Several sensitive plant species were reported in the California Natural Diversity Database (CNDDB) as recorded within a 12 -quad search of the city, although the majority of these species are not expected to be present within city limits for one or both of the following reasons: suitable habitat to support the species is not present within the city; or the species occurrences are highly localized some distance from the city. Table 2-3 describes the habitat requirements and status of each sensitive plant species with a low, moderate, or high potential to occur within the city, as determined through the literature review and habitat evaluations made during the reconnaissance survey. A selection of these species within close proximity to the Planning Area are mapped in Figure 2-2. 18 1.1 Packet Pg. 213 Existing Conditions Report — Volume 111, January 2017 Environmental Constraints and Opportunities; Public Facilities, Services, and Utilities Table 2-3: Special Status Plant Species Species Status'Federal/State/ CRPR Habitat Requirements Potential to Occur Round -leaved --/--/ I B.2 Annual herb found in clay soils and associated Moderate.

As shown in Figure 2-4, the Planning Area drains into four subbasins of the San Gabriel River Basin. The northern half of the city primarily drains into San Jose Creek, partially via Diamond Bar Creek. Most of the southern half of the city, as well as the SOI, drains into Brea Canyon Creek. Small areas in the northeast of the city are within the Santa Ana River Basin, draining locally into Chino Creek. The Federal Emergency Management Agency (FEMA) flood map identifies flooding hazards of various intensities. As shown in Figure 2-5, there are two portions of the Planning Area that are within the 100 -year flood zones, which are areas having a 1.0 percent chance of flooding in a given year. The only 100 -year flood zone within the city limits lies near the intersection of Brea Canyon Road and Lycoming Street, along the Reed Canyon Channel. Another 100 -year flood zone runs through Tonner Canyon Creek in the SOI. Some potential for flooding has also been reported in the City of Industry between Temple and Lemon Avenues, even though FEMA has not designated this area as a flood zone. 26 1.1 Packet Pg. 221 GENERALPLA Figure 2-4:WatershecLs and,-� Dia Surface Water A.

The information provided in this section is based on a cultural resource records search conducted through the California Historical Resources Information System (CHRIS) South Central Coastal Information Center (SCCIC); a Sacred Lands File (SLF) search commissioned through the Native American Heritage Commission (NAHC); and a paleontological resources records search commissioned from the Natural History Museum of Los Angeles County (NHMLAC). CULTURAL AND NATURAL SETTING Ethnographic Setting — The Gabrielino The city is located within Gabrielino (Gabrieleiio, Tongva, or Kizh) territory. According to Bean and Smith (1978:538), the Gabrielino, with the exception of the Chumash to the north, "were the wealthiest, most populous, and most powerful ethnic nationality in aboriginal Southern California." Named after the San Gabriel Mission, the Gabrielino occupied sections of Los Angeles, Orange, and San Bernardino counties, and the islands of San Nicolas, Santa Catalina, and San Clemente. The Gabrielino subsisted on a variety of resources in several ecological zones. Acorns, sage, and yucca were gathered throughout the inland areas whereas shellfish, fish, as well as a variety of plants and animals were exploited within the marshes and along the coast. Deer and various kinds of small mammals were hunted on an opportunistic basis. Their material culture reflected the subsistence technology. Lithic tools such as arrow points and modified flakes were used to hunt and process animals. A variety of ground stone grinding implements, such as the mortar, pestle, mano, and metate, were used to process both plant and animal remains for food.31 The settlement patterns of the Gabrielino, and other nearby groups such as the Juaneho and Luisefio, were similar and they often interacted through marriage, trade and warfare. The seasonal availability of water and floral and faunal resources dictated seasonal migration rounds with more permanent villages and base camps being occupied primarily during winter and spring months. In the summer months, the village populations divided into smaller units that occupied seasonal food procurement areas. The more permanent settlements tended to be near major waterways and food sources and various secular and sacred activities, such as food production and storage and tool manufacturing, were conducted at these areas.32 Early History and Development of the City of Diamond Bar European contact with the Gabrielino that inhabited the city and surrounding region began in 1542 when Spanish explorer, Juan Rodriguez Cabrillo, arrived by sea during his navigation of the California coast. Sebastian Vizcaino arrived in 1602 during his expedition to explore and map the western coast that Cabrillo visited 60 years earlier. In 1769, another Spanish explorer, Gaspar de Portola, passed through Gabrielino territory and interacted with the local indigenous groups. In 1771, Mission San Gabriel was established and it slowly integrated Gabrielinos from the 31 Bean, L. J., and C. R. Smith, 1978, Gabrielino.

Smithsonian Institution, Washington. 32 Ibid. 29 Packet Pg. 224 Diamond Bar General Plan Update surrounding region and, quite possibly, the city. By 1833, the California missions had been secularized and most Gabrielinos became laborers for the gentry class.33 In 1840, the governor Juan Alvarado deeded 4,340 acres (which included parts of Diamond Bar), to Jose de la Luz Linares. Linares established Rancho Los Nogales, or "Ranch of the Walnut Tree", with this Mexican land grant. He died in 1847 and his widow sold a choice portion of the ranch to Ricardo Vejar for $100 in merchandise, 100 calves, and the assumption of her late husband's debt. Vejar already owned the nearby Rancho San Jose (now the City of Pomona) so this acquisition made him the fifth wealthiest landowner in Los Angeles County, with 10,000 acres. Starting in 1964, the land that encompassed the original Rancho Los Nogales changed ownership over the next several decades. One such owner was Louis Phillip, a young livestock owner who subdivided portions of the ranch for sale.34 Frederick E. Lewis II purchased 7,800 acres of the original ranch in 1918. Soon thereafter, Lewis formed the Diamond Bar Ranch and registered the "diamond over a bar" branding iron with the California Department of Agriculture. This would later become the symbol for which the City of Diamond Bar was named. Diamond Bar Ranch became a successful ranch primarily through hog breeding, although other activities such as horse breeding also took place on site.35 In 1943, Lewis sold the Ranch to the Bartholomae family, who continued to maintain it as a successful ranch by raising cattle on it for the next thirteen years. William A Bartholomae was president of the family oil company and in 1956 sought to make a more lucrative use of the land. At that time the Ranch looked much as it did in 1840, with grassy rolling hills supporting large herds of cattle, as well as abundant walnut tree orchards and scattered oak trees. The Christiana Oil Corporation and the Capital Oil Company, a subsidiary of the Transamerica Corporation, purchased 8,000 acres of Brea Canyon for $10,000,000, which encompassed the Ranch and the Ranch Headquarters Compound. Their plan was to develop a master -planned community that would eventually become home to more than 50,000 people. A masterplan was adopted in 1958 and work began immediately on utilities and infrastructure. The plan included a central business district, two shopping districts, and parks including a 18 -hole golf course. Education was also considered a very important aspect of the plan.36 The first model homes were built in 1960 in the north end of the city and the development continues to this day. After a lengthy process, the City incorporated in 1989 and became Los Angeles County's 86th city.37 38 A 33 Bean, L. J., and C. R. Smith, 1978, Gabrielino.

The Peninsular Range is characterized by a well-defined geologic and physiographic unit which extends southeastward from Los Angeles to the southern tip of Baja California for a distance of 900 miles.40 This province is described by a southeast to northwest structural grain that is best illustrated by a series of faults connected with the San Andreas fault system (consisting of the Whittier fault and the Newport - Inglewood fault in the Los Angeles basin) and by northwest -trending folds (made up of the Santa Ana Mountains and the Puente and Coyote Hills). The city consists of a series of interconnected valleys and rolling hills ranging in elevation from 500 to 1,470 feet. In addition, the City of Diamond Bar is also underlain by marine -derived sediments that are thousands of feet thick as part of the fossiliferous Puente Formation.41 A discussion of geological hazards in the Planning Area is included in Section 2.7. According to a review of the geologic map for Los Angeles Basin, the city is located within areas designated as Qal, Tpy, Tpsq and Tplv rock units. Qal is described as recent Quaternary alluvium deposits and the lithology is made up of gravel, sand, and silt of alluvial -fan and flood -plain origin. Schoellhamer et al. (1954) indicate that Tpy, Tpsq and Tplv are deposits associated with the Puente Formation from the Upper Miocene age of the Yorba, Soquel and La Vida members. Below is a description of each member by Schoellhamer et al. (1954).42 Yorba Member: This member is characterized by a "[t]hin bedded gray siltstone, diatomaceous siltstone, and local sandstone and conglomerate; marine" (pg. 8). Soquel Member: The lithology of this rock unit is composed of a "[m]assive to well -bedded, coarse to gritty feld-spathic sandstone; marine" (pg. 8). La Vida Member: This member is categorized as "[g]ray to black, laminated siltstone, with interbedded feld-spathic sandstone; marine" (pg. 8). RESOURCES IDENTIFIED WITHIN THE CITY AND VICINITY Archaeological Resources The results of the cultural resources records search indicated that a total of 87 cultural resource studies have been conducted within the one-half mile radius of the city. Of these 87 studies, 55 have been conducted within the city limits. The SLF records search revealed that no known Native American resources from the NAHC database have been recorded within the city. The results of the cultural resources records search also indicated that a total of 13 cultural resources (see Table 39 City of Diamond Bar and Diamond Bar Historical Society, 2014, Images of America, Diamond Bar. Copyright 2014. ISBN 978-1-4671-3196-4. Published by Arcadia Publishing, Charleston, South Carolina. 40 H. Richard and Ed Jahns, 1954. Geology of Southern California. Bulletin 170. Volume 1.

Yerkes, 1954, U.S. Geological Survey, Geology of the Los Angeles Basin. 31 Packet Pg. 226 Diamond Bar General Plan Update 2-5) have been recorded within the one-half mile radius of the city. Of the 13 cultural resources previously recorded, seven are located within the city limits. These seven resources consist of five prehistoric archaeological sites (19-002805, CA -LAN -1704, CA -LAN -852, CA -LAN -853 and CA - LAN -854), one prehistoric isolate (19-101010), and one historic archaeological site (CA -LAN - 3771H). The SLF records search revealed that no known Native American resources from the NAHC database have been recorded within the city; however, this does not preclude their existence with the city. Paleontological Resources The results of the paleontological records search indicated that one vertebrate fossil locality exists within the boundaries of the city and that several other localities from the same sedimentary deposits occur nearby. Low lying terrain areas (such as Brea Canyon and San Jose Creek) consist of younger Quaternary Alluvium derived from the drainages, which are not known to contain significant vertebrate fossils in the uppermost layers. However, at shallow depths there are older sedimentary deposits that have the possibility of yielding significant vertebrate fossils. The closest vertebrate fossil locality from older Quaternary Alluvium deposits is LACM 8014, located southwest of the intersection of SR -60 and SR -71 (approximately 1/2 mile east of the northeastern boundary of the city), which produced a fossil specimen of bison. Another locality from these same deposits is LACM 1728, located east of the mid -east boundaries of the city (exact location unknown), yielded fossil specimens of a horse and camel at a depth of 15 to 20 feet below surface. Elevated portions of the Puente Hills within the city also have exposures of the marine late aforementioned Miocene -aged [approximately 23 million years ago (Ma) to 5.3 Ma] Puente/Monterey Formation. One vertebrate fossil locality (LACM 7190) from the Puente/Monterey Formation is located within the southwestern boundaries of the city (southwest of the intersection of SR -60 and SR -57), which yielded a fauna of fossil fish including deep sea smelts, lantern fish, jacks and herrings. Other localities from the Puente Formation also exist outside the city's boundaries and these include LACM 7153, 6171, 5837, 6170 and 7490-7492. LACM 7153 (located approximately 1.5 miles west of the northernmost portion of the city) produced many specimens of fossil pipefish. LACM 6171 (located approximately three miles northwest of the city's boundaries) in the San Jose Hills produced a fossil fish specimen of herring. LACM 5837 and LACM 6170 (located approximately 2.5 miles from the mid -western boundaries of the city) yielded fossil fish specimens of scad and oilfish. LACM 7490-7492 (located approximately 2.5 miles east of the east -central boundaries of the city) produced a suite of marine fish including deep sea smelt, scad, herrings, croaker, mackerel and snake mackerel. Shallow excavations into younger Quaternary Alluvium deposits within the city are not likely to yield paleontological resources. However, deeper excavations within the city (that extend down into older Quaternary deposits or into the Puente Formation) have the potential to encounter paleontological resources. 32 1.1 Packet Pg. 227 1.1 Existing Conditions Report — Volume III, January 2017 Environmental Constraints and Opportunities; Public Facilities, Services, and Utilities Tribal Cultural Resources The City will conduct the appropriate SB 18 and/or AB 52 consultations on a project -by- project basis with the appropriate Native American tribes in order to identify the presence of tribal cultural resources within the city. Historical Resources Out of the 13 cultural resources previously recorded within the one-half mile radius within the City of Diamond Bar, two built environment resources are located within the city and these consist of a small segment of the Union/Southern Pacific Railroad (Primary Number 19-186112) and a ground water tank/reservoir (Primary Number 19-189748). The segment of the Union/Southern Pacific Railroad (Primary Number 19-186112) was originally recommended eligible for the National Register of Historic Places (National Register) in 1999; however, it was revaluated in 2009 and recommended ineligible for listing at the local, State, and national levels due to the loss of integrity. The ground water tank/reservoir (Primary Number 19-189748) was evaluated in 2010 and found ineligible for the National Register through the Section 106 process, but was not evaluated at the State or local levels. 33 Packet Pg. 228 1.1 Diamond Bar General Plan Update Table 2-5: Previously Recorded Cultural Resources Permanent No. Trinomial (P 19) (CA -LAN) Description Date Recorded Eligibility * 19-186112 Built -environment resource consists of a 1999 N/A segment of the Union/Southern Pacific Railroad. ................................................................................................................ *19-002805 ..........................................................................................................................................................................................................................................................................

The city is surrounded by natural areas to the east in Tres Hermanos Ranch and the south in Tonner Canyon, and there are still many hillsides that remain undeveloped. In addition, many homes in Diamond Bar have older, wood shingle roofs, and strong winds that can easily spread fires are known to occur in the area. Even with these risks, the Insurance Service Organization (ISO) gave the city a rating of three in 2000, which is a good rating for an urban area.43 This rating takes into account natural risks as well as the provision of fire protection services (discussed in Section 7-3). As shown in Figure 2-6, the California Department of Forestry and Fire Protection (CAL FIRE) has designated several areas along the southern and western edges of the city as Very High Fire Hazard Severity Zones, which all have significant elevations. Many of these areas are vacant or open space areas, though the majority of the Country Estates subdivision is also designated as high risk. The entirety of the SOI, which consists mostly of open space on steep slopes, is designated as a fire hazard, with the vast majority rated by CAL FIRE as a Very High Fire Hazard Severity Zone. 2.6 Hazardous Materials and Sites Sites where hazardous chemical compounds have been released into the environment can pose health threats. Historic or current activities, most often associated with industrial or commercial uses (including gas stations, car washes, etc.), may result in the release, leak, or disposal of toxic substances on or below the ground surface, where they can then contaminate soil and ground water. Furthermore, disturbance of the ground through grading or excavation can result in exposure of these chemicals to the public. Improper handling of contaminated sites may result in further exposure via airborne dust, surface water runoff, or vapors. Hazardous sites designated by both the State Water Resources Control Board (SWRCB) and the California Department of Toxic Substances Control (DTSC) are shown on Figure 2-7 and listed in Table 2-6. Contaminated sites are largely found along the city's major local roadways (e.g., Diamond Bar Boulevard, Grand Avenue, Golden Springs Drive), particularly near where those local roadways intersect SR -57 or SR -60. The majority of the hazardous sites are classified as Leaking Underground Storage Tank (LUST) cleanup sites; many of these sites are automobile -related, such as gas stations. 43 The ISO rating is from one to ten, with one being the best score reflecting the lowest risk. 1.1 35 Packet Pg. 230 1.1 Diamond Bar General Plan Update Table 2-6: Hazardous Materials Sites in Planning Area Site Name' Address Status' LUST Cleanup Site Al Sal Oil #26 301 Diamond Bar Blvd S Completed - Case Closed Arco #5528 780 S Brea Canyon Rd Completed - Case Closed Arco #6212 3302 Diamond Bar Blvd Completed - Case Closed Caltrans Diamond Bar Maintenance 21420 Golden Springs Dr E Completed -Case Closed Station Chevron #9-0679 150 Diamond Bar Blvd S Completed - Case Closed Chevron #9-1175 21095 Golden Springs Dr Completed - Case Closed Chevron #9-8559 (Former) 2707 Diamond Bar Blvd Completed - Case Closed Chevron Service Station Former 23671 Golden Spring Dr Open - Site Assessment Chevron Service Station No/9-1 175 21095 Golden Springs Rd E Completed - Case Closed Conoco Phillips Company #2705690 2875 Diamond Bar Blvd S Open - Remediation Diamond Bar Country Club 22751 Golden Springs Dr E Completed - Case Closed Diamond Bar Honda 525 Grand Ave S Completed - Case Closed Exxon #7-2882 (Former) 350 Diamond Bar Blvd S Completed - Case Closed LA Co FD Fire Station #1 19 20480 Pathfinder Rd E Completed - Case Closed LA Co FD Fire Station #121 346 Armitos PI Completed - Case Closed LA Sun West Virginia Industrial 20445 Walnut Dr N Completed - Case Closed Mobil #-18-002 504 Diamond Bar Blvd N Completed - Case Closed Mobil #1 1-1 14 22628 Golden Springs Dr E Completed - Case Closed Mobil #18-P6V 350 Diamond Bar Blvd S Completed - Case Closed Mobil 18-114 22628 Golden Springs Dr Completed - Case Closed Mobil Station 18114 22628 Golden Springs Drive Never Active - WDR Shell 206 Diamond Bar Blvd S Completed - Case Closed Shell (Texaco Refining & Marketing) 21 103 Golden Springs Dr Completed - Case Closed Shell #204-2173-0274 206 Diamond Bar Blvd S Completed - Case Closed Shell #204-2173-0308 3241 Brea Canyon Rd S Completed - Case Closed Shell Service Station 3241 Brea Canyon Road Completed - Case Closed Unocal #5683 2875 Diamond Bar Blvd S Completed - Case Closed Cleanup Program Site Chevron -Diamond Bar 2707 Diamond Bar Blvd Completed - Case Closed Country Hills Cleaners 1 155 S Diamond Bar Blvd Open - Site Assessment - Land Use Restrictions Country Hills Towne Center 2809 South Diamond Bar Completed - Case Closed Boulevard Expert Cleaners (Former) 20627 East Golden Springs Dr Completed - Case Closed 36 Packet Pg. 231 1.1 Existing Conditions Report — Volume 111, January 2017 Environmental Constraints and Opportunities; Public Facilities, Services, and Utilities One Hour Cleaner 1 164 S Diamond Bar Blvd Completed - Case Closed Permitted Underground Storage Tank (UST) LA Co DPW Sewer Fountain Springs 21418 E Fountain Springs Rd Completed - Case Closed Mobil #18-E67 (Former #1 1-E67) 1024 Brea Canyon Rd S Completed - Case Closed Evaluation Country Hills Cleaners 1 155 S Diamond Bar Blvd Refer - 1248 Local Agency Voluntary Cleanup Former Diamond Jim's Dairy 23671 Golden Springs Road Refer - RWQCB Oak Tree Plaza 916 N Diamond Bar Blvd No Further Action Notes: I.

SEISMICITY Diamond Bar is located in a region with several major active faults. The San Andreas Fault Zone, which has the greatest potential to cause damage in the region, is 26 miles northeast of the city. The Planning Area, however, is at greater risk from the active local faults of Whittier, San Jose, Sierra Madre, and San Gabriel. GEOLOGY AND SOILS A discussion of the Planning Area's geological setting and soils is included in Section 2.4. The type of soil in an area will affect liquefaction susceptibility, shrink -swell potential, and the potential for landslides. Liquefaction is the rapid transformation of saturated, loose, fine-grained sediment (such as silt and sand) into a fluid state as a result of severe vibratory motion. Expansive soils with shrink - swell capacity may swell when wetted and shrink when dried. The higher the clay content of a soil, the higher its shrink -swell potential. Local soils in the Planning Area are largely the result of bedrock materials that have weathered, consisting of a variety of sandstones, shales, and siltstones. The natural canyons in the area contain alluvial, or stream -carried, materials, while artificial fill is present in areas that have been developed. Landslides, also referred to as slope failures, include many phenomena that involve the downslope displacement and movement of material, either triggered by static (i.e., gravity) or dynamic (i.e., earthquake) forces. Exposed rock slopes may undergo rockfalls, rockslides, or rock avalanches, while soil slopes may experience shallow soil slides, rapid debris flows, and deep-seated rotational slides. Landslide -susceptible areas are characterized by steep slopes, downslope creep of surface materials, and unstable soil conditions. As shown in Figure 2-8, the majority of the Planning Area's residential neighborhoods, as well as the majority of the SOI, contain steep slopes that have increased risk of landslides, including hillsides that have historically been unstable. 41 Packet Pg. 236 1.1 Diamond Bar General Plan Update This page intentionally left blank. 42 Packet Pg. 237 Steep Slos�. 71�e GENERAL PLAN 1.1 r ,o � � \, + City of Diam o NGHLANDVLYRD `\ N"°"IwGRo Pomo j 1 SONSETCROSSINGq �. �� A ° yP�GLEN .� .� se A �l �t pRMliO -� Ca, � aANrE� r 4141 SIndustry- !

Noise is defined as sound that is loud, unpleasant, unexpected, or undesired. Noise levels are measured in decibels (dB) with 0 dB roughly equal to the threshold of hearing and 100 dB equal to the sound of an ambulance. According to common practice, maximum noise levels of 60 dB are considered "normally acceptable" for unshielded residential development. Noise levels from 55 to 70 dB fall within the "conditionally unacceptable" range, and those in the 70 to 75 dB range are considered "normally unacceptable." The City of Diamond Bar's noise control ordinance contains more exacting standards for noise exposure. Exterior noise standards range from 45 dB for noise -sensitive areas and residential properties to 70 dB for industrial properties, as shown in Table 2-7. Table 2-7: Exterior Noise Standards Designated Noise Zone Land Use Noise Zone (Receptor Property) Time Interval Noise -sensitive area 11 Residential properties III Commercial properties IV Industrial properties Source: Diamond Bar Municipal Code, Section 8.12.530.

The major sources of noise within the city include typical urban noise levels such as vehicle traffic along roadways, industrial and commercial processes, and residential noises such as people talking, sports events in parks, and vocalizations from domesticated animals. Many land uses are considered sensitive to noise. Noise -sensitive receptors are land uses associated with indoor and/or outdoor activities that may be subject to stress and/or significant interference from noise, such as residential dwellings, transient lodging, dormitories, hospitals, educational facilities, and libraries. Industrial and commercial land uses are generally not considered sensitive to noise. Special Status species and their habitat are also considered noise -sensitive. Noise -sensitive receptors within the city include single- and multi -family residential housing, schools, parks, libraries, hospitals, churches and other religious facilities, wildlife habitat, and open space. Vehicular traffic is the predominant noise source within the city. Freeways within the city include SR -57 and SR -60. Arterial streets within the City include Brea Canyon Road, Chino Avenue, Chino Hills Parkway, Diamond Bar Boulevard, Golden Springs Drive, Grand Avenue, Lemon Avenue, 45 Packet Pg. 240 1.1 Diamond Bar General Plan Update and Pathfinder Road. The level of vehicular traffic noise varies with many factors, including traffic volume, vehicle mix (including percentage of trucks), traffic speed, and distance from the roadway. EXISTING AMBIENT NOISE SURVEY To characterize existing ambient noise conditions at and within the vicinity of the project site, a total of two long-term (24-hour) and eight short-term (15 -minute) noise level measurements were conducted throughout the city on October 24-25, 2016, to provide a representative sample of daytime and nighttime noise conditions. The noise measurements were conducted using a Larson Davis LxT sound -level meter (SLM), which was calibrated prior to and after each measurement to ensure the accuracy of the measurements. The results of the short-term noise measurements are shown in Table 2-8. The measurement locations are identified in Figure 2-9.

The FHWA model calculates the average noise level at specific locations based on traffic volumes, average speeds, and site environmental conditions. Existing roadway noise contours are shown in Figure 2-10. The model assumed "hard surface" site propagation conditions. Sound levels caused by line sources, relatively long, variable or moving sound sources such as traffic, decrease at a rate of 3.0 to 4.5 A -weighted decibels (dBA) when the distance from the centerline of the road is doubled, depending on the surface hardness between the source and the receiving property. The actual sound level at any receptor location is dependent upon such factors as the source -to -receptor distance and the presence of intervening structures, barriers, and topography. Attenuation due to intervening structures, topography, atmospheric absorption, etc. is not included in the generalized model; therefore, the model analysis assumes a conservative worst-case scenario for traffic noise (i.e., actual site attenuation would potentially result in reduced traffic noise levels at receptors, where intervening structures and topography occur). 47 Packet Pg. 242 1.1 Diamond Bar General Plan Update This page intentionally left blank. 48 Packet Pg. 243 Figure 2-9: Noise Measurement Locations Walnut Metrolink Station LYCOM ING ST 2 3 PO Industry SAN 9 Op Z SELLA PINE DR C e r n P P 'h0 R2 e CROSSING RO GENERAL PLAN 1.1 City of Diam ""'3,H LAND VLY ED Q' H `QOSSING RD ate+: : a N4H 1 Pomona HJ2h p �o]>,`,� P2GlENP 1 QED � 5y I _&RI ORAH RD D PP�DM\NO DR AID R7 FNA DR .� PRMROSQ (f PANTE,q\\ Oy a 1 CANEONRID \ LOSANGELES COUNTY N L--------., R 10,111411" P C 1 SCO � OpJ \ I I I 1 I I I 1 I ------------------------- o --------------a Noise Measurement Locations HighwaysWater Features Long-term (24 -hr): RI and R2 — Short-term (15 min): R3 through R 10 – Ramps L _ City of Diamond Bar Major Roads �1 Sphere of Influence Local Roads County Boundary -,-, Railroads Source: City of Diamond Bar 2016; ESA PCR, 2016; 0 0.375 0.75 1.5 D Y Dyett & Bhotio, 2016 MILES urban Packet Pg. 244 Figure 2-10: Existing Noise Contours Walnut Metrolink Srn�tion ITV /.w LYCOMINGST t � �V LOS ANGELES COUNTY CROSSING RO Industry - 0 / C9 y NEO�R\/ W pCF jr MOUNT0 MOUNTAIN LA SAIV, 2 BELIA PINE, CFyN� °2 a� a° ? 9l N CANYON RIDC r V P O S CCN REq r NrGH LAND I" RD ep5S1NG RD J J� h O OEC D eP �M\Np DR� �pCDRUSyI GENERAL PLAN 1.1 City of Diam 2GlENPO JP hJ ° w T W hae 1 P�.OJSNEitS SJ o x I p0 I ° 1 NP�F� I 1 i 1 / I i j 1 / 1 0 I `\ / v / e I q 1 < Existing Noise Levels _ 75 dB Contour �I 70 dB Contour 65 dB Contour 60 dB Contour Highways Ramps Major Roads Local Roads -- Railroads Water Features L_ City of Diamond Bar 41 Sphere of Influence County Boundary Pomona Source: City of Diamond Bar 2016; ESA PCR, 2016; o 0.375 0./5 1.5 D Y Dyett & Bhotio, 2016 MILES Urban Packet Pg. 245 1.1 3 Public Facilities, Services, and Utilities 3.1 Parks, Trails, Recreation, and Community Facilities PARKS Parks provide places for Diamond Bar residents to exercise, relax, and socialize outdoors. There are four park types in Diamond Bar. Community parks are the largest, ranging in size from 20 to 50 acres. Owing to their size and service area, Community Parks typically feature more amenities than the other kinds of parks, including community buildings, informal open play areas, playgrounds, picnic areas, shelters, lit sports fields and courts, public restrooms, and onsite parking. The City hosts major events in Community Parks that attract residents from across Diamond Bar. Popular events include the Concerts in the Park Series at Sycamore Canyon Park, Movies Under the Stars at Sycamore Park, the City Birthday Party at Pantera Park, and the Winter Snow Fest at Pantera Park. Neighborhood Parks and Mini Neighborhood Parks are found in residential subdivisions. They are intended to serve surrounding neighborhoods within a one -mile radius. However, the functional service area of neighborhood parks may be different than a strict one -mile radius due to the layout of the circulation network (see discussion of "walksheds" below). Neighborhood Parks range in size from three to six acres, while Mini Neighborhood Parks range from 1/4 to three acres. They often include playgrounds, practice sport fields and courts, and public restrooms. Specialty parks, the final park type, provide a single use or function, and can include dog parks, equestrian centers, and skate parks. Diamond Bar's existing park facilities are listed in Table 3-1. Other parks and recreational facilities, including private facilities, and the County -run Diamond Bar Golf Course, are listed in Table 3-2. Undeveloped and planned parks are found in Table 3-3. Figure 3-1 shows the mile and half -mile service radii of existing parks, as well as the five minute and ten minute walksheds (which follow the actual roadways and pathways, rather than "as the crow flies" radii). Many residential areas in the city do not have an existing park within a ten-minute walk, which is partly due to the curvilinear street pattern in steeply sloped areas. The addition of park space within the designated Planning Areas would increase park accessibility for many residents, as Larkstone Park will soon accomplish for PA -4 and the residential area surrounding South Pointe Middle School.

There are currently 73.2 developed acres of parkland in Diamond Bar, for a total of 1.30 park acres per 1,000 residents. Adding planned parks to this current total, the figure increases to 1.42. The figure falls short of the target park threshold even when adding undeveloped park space to the dedicated parkland total. Table 3-4 shows calculations of park acres per 1,000 residents.

Trails offer hikers (and in some cases, cyclists) views of natural landscapes and views of the surrounding city. The Summitridge Trail System is the most comprehensive trail network in Diamond Bar and features an extensive system of interconnected trails. The Pantera, Peterson, and Sycamore Canyon Trails span through undeveloped, natural areas of city parks. The 2011 Parks and Recreation Master Plan set forth goals to improve the existing trail system, including by installing mile markers and benches, and programming educational activities. Planned trails include the Crooked Creek Trail, the Tonner Canyon Trail, the Schabarum Trail, and the Sandstone Canyon Trails.

Recreational activities and programming is scheduled in Diamond Bar year-round. joint Use Agreements The City has joint use agreements with the Pomona Unified School District and the Walnut Valley Unified School District to use gyms for adult basketball and volleyball programs. The City also has a joint agreement with Pomona Unified School District to use the lighted football field at Lorbeer Middle School in exchange for maintenance. COMMUNITY FACILITIES Community facilities in Diamond Bar, as shown in Figure 3-2, include City Hall, three community centers, and a library. Diamond Bar's City Hall is located at 21810 Copley Drive, a building the City purchased in 2011 after leasing space across the street in the South Coast Air Quality Management District (AQMD) complex for 11 years. Since 2012, the building's first floor has also been home to the Diamond Bar branch of the Los Angeles County Library. This co -location has allowed the facility to function as a true community center, with many new programs and activities. The Diamond Bar Center (DBC), located in Summitridge Park, is a 22,500 -square -foot facility containing banquet and meeting rooms, accommodating parties of up to 438 people and up to 1,000 people for meetings. Its popularity as location for weddings and conferences results in long advance bookings, pointing to potential need for additional banquet and meeting facilities in the city. The Center also hosts meetings from several senior clubs in the city, though there is no dedicated space in the city for seniors. A pad for a freestanding building is located on the grounds of the DBC, which was once contemplated as a potential library site. The Heritage Park Community Center is located at 2900 S Brea Canyon Road. It accommodates up to 110 for dining and up to 200 for theatre events. The Pantera Park Activity Room accommodates groups up to 50. Both facilities host classes and workshops. 56 1.1 Packet Pg. 251 Existing Conditions Report — Volume III, January 2017 Environmental Constraints and Opportunities; Public Facilities, Services, and Utilities 3.2 Public Schools SCHOOLS The Planning Area is served by two school districts, the Pomona Unified School District (PUSD) and the Walnut Valley Unified School District (WVUSD). Grand Avenue is a rough delineation between the two districts, with areas north served by PUSD and areas south served by WVUSD. The boundaries of the school districts are shown in Figure 3-2. Walnut Valley Unified School District WVUSD serves approximately 14,400 enrolled K-12 students within portions of the cities of Diamond Bar, Industry, West Covina, and Walnut, as well as portions of unincorporated Los Angeles County. It is one of the top performing school districts in the state, with Diamond Bar High ranking particularly high. As shown in Table 3-6, WVUSD schools within the Diamond Bar city limits serve 3,008 students in five elementary schools, 2,129 students in two middle schools, and 3,062 students at one high school. The District office is located at 880 South Lemon Avenue in Diamond Bar. WVUSD enrollment decreased from 15,512 students in 2005-2006 to 14,464 students in 2015-2016, a drop of 6.8 percent. WVUSD's middle schools in Diamond Bar as well as Diamond Bar High currently have excess capacity, though multiple WVUSD elementary schools in Diamond Bar are currently operating above capacity. School enrollment projections for WVUSD are based on birth rates and cohort survival factors alone, as projected residential development is not considered significant enough to affect the projections. Projections from WVUSD's 2016 Districtwide Facilities Action Plan anticipate that student enrollment will continue to decline through 2018-2019, followed by a period of growth. While excess capacity is predicted in the next ten years for middle schools and Diamond Bar High, the total seat shortage for WVUSD elementary schools in Diamond Bar is expected to grow from under 60 in 2015-2016 to over 660 in 2025-2026. The Facilities Action Plan suggests a need for an additional elementary school or the expansion of existing elementary school campuses to accommodate future enrollment growth. The excess capacity at the middle school level will be necessary to accommodate current elementary school students as they matriculate into middle school. While WVUSD is high performing, it is one of the most underfunded districts in the state based on the Local Control Funding Formula, and they are exploring partnerships to better secure their finances. Pomona Unified School District PUSD has seen declining enrollment at a more rapid pace than WVUSD, losing roughly 8,000 students in the past ten years as families in the district have moved further inland to San Bernardino County and beyond, as well as due to the District of Choice program discussed below.44 As shown in Table 3-6, enrollment at both Diamond Point Elementary and Golden Springs Elementary is at 44 Interview with Richard Martinez, Superintendent of Pomona USD, September 29, 2016. 1.1 57 Packet Pg. 252 Diamond Bar General Plan Update less than half of capacity, while elementary schools in WVUSD are all approaching or exceeding capacity. PUSD's district -wide student enrollment projections are driven by recent kindergarten enrollment trends modified by live birth data, changes in the grade -level cohorts of students served as they age through, and changes in the district's number of residential units. These projections are then disaggregated to individual schools based on the rate at which each school draws enrollment from various sections of the district, as well as the pattern of transfers within the district at a given level from one school to another. Growth projections are flat for the next five years, and while new housing developments in the City of Pomona should help their enrollment numbers, if trends persist, PUSD may need to repurpose multiple school buildings. Diamond Point is the smallest school in the city, and neighboring Golden Springs Elementary could absorb its student population if it were repurposed, though such an action is likely to face significant community opposition. PUSD's budget is solvent, notwithstanding the declining enrollment. The District owns approximately 141.4 acres of land near Diamond Ranch High School, of which 31.1 acres is within the City of Diamond Bar. The Board of Education has yet to determine a use for this property, which faces limitations in that it is difficult to access and grading costs would be very expensive; however, the District is considering a sale or lease of the property to outside entities. Interdistrict Transfers WVUSD enrolls a large number of students that reside outside of the school district boundaries, primarily due to the District of Choice ("DOC') program, which allows any student to attend their schools regardless of the student's home address and without seeking permission of their home districts. Incoming students that attend WVUSD but reside in another school district are referred to as interdistrict transfers ("IDTs"). Typically, IDTs are approved based on an agreement with the school district of origin, parental employment within the School District, or the DOC program. The share of IDTs has been increasing in recent years, from 30 percent of enrolled students in 2012- 2013 to 34 percent in 2015-2016. 58 1.1 Packet Pg. 253 Figure 3-2: Schools & Other Public Facilities Walnut Metrolink Station Walnut T E.S.

Of the roughly 10,000 students participating in the DOC program statewide, about 3,400 are enrolled in WVUSD. If the legislation is not renewed, WVUSD may lose around a quarter of its student enrollment, in which case it may be forced to lay off many teachers and potentially even close schools as a result. On the other hand, PUSD stands to boost its enrollment if DOC ends, though as many of the PUSD schools in Diamond Bar are high performing, they may not receive as many students as PUSD schools outside of Diamond Bar. Armstrong Elementary, for example, is a PUSD elementary school that receives a lot of transferring students, including from WVUSD. 3.3 Public Safety Services POLICE SERVICE Police services in the Planning Area are provided by the Los Angeles County Sheriff s Department. The Walnut/Diamond Bar Regional Station, located at 21695 East Valley Boulevard in Walnut, services both cities, as well as Rowland Heights. In the case of emergency, the San Dimas and Industry Stations can provide additional assistance. The County Sheriff s Department also provides general -service law enforcement to unincorporated areas of Los Angeles County, including areas south of Diamond Bar's city limits that are within its SOI. The County Sheriffs Department provides a full range of police services, as shown in Table 3-7. The staffing numbers displayed reflect only those law enforcement personnel dedicated to the City of Diamond Bar, even though law enforcement services are also provided to the city of Walnut and Rowland Heights out of the same station. According to the City's budget for Fiscal Year 2016-2017, about one quarter of the City's General Fund expenditures are dedicated to public safety, and 96 percent of those expenditures are allocated toward law enforcement.

This ratio may seem deceptively low when police service ratios typically are measured per 1,000 residents, though this ratio merely represents the minimum service level guaranteed by the County Sheriffs Department to any communities that purchase their services. This minimum service ratio is far exceeded in Diamond Bar, and the County Sheriffs Department has many more resources that can be brought to bear when needed, which makes the effective service ratio much higher. The County Sheriffs Department maintains other facilities offsite that are available the city immediately, including the Homicide Bureau, Aero Bureau, OSS (gang unit), and Traffic Services Bureau. If needed, 26 other stations in the County Sheriffs Department are also available to send resources to Diamond Bar. As shown below in Table 3-8, the average response time in 2016 was under five minutes for emergency calls, just over 8 minutes for priority calls, and under 21 minutes for routine calls, all of which were well within the department standards. According to the County Sheriffs Department, the major obstacles to meeting response time standards are traffic during peak rush hour, and traffic in and around the schools during the beginning and ending of business hours. Table 3-8. Response Standards and Times for Police Calls Police Service Response Time (Minutes) Department Standard Diamond Bar (2016) Emergency Calls 7 minutes 4.7 minutes Priority Calls 15 minutes 8.1 minutes Routine Calls 30 minutes 20.9 minutes Source: Los Angeles County Sheriff's Department, 2016. FIRE SERVICE Fire protection and emergency medical services are provided by the County of Los Angeles Fire Department, which operates three stations within Diamond Bar's city limits, as shown in Figure 3- 3. In addition to fire protection service and emergency medical services, the Fire Department provides personnel to serve on specialized rescue teams, offer special training programs, and inspect businesses for fire safety. These services are paid for through local taxes. The County Fire Department does not have service ratio standards (i.e. number of responders per 1,000 residents), as the department finds that these standards do not account for factors such as non-residential demand, car accidents, transient population, and vacant land that poses fire hazards. They instead follow national guidelines that require a five-minute response time for first - arriving fire and EMS units and eight minutes for paramedic units in urban areas, as well as eight - minute response time for first -arriving fire and EMS units and 12 minutes for paramedic units in suburban areas. In 2015, the average response time for fire and emergency calls in the City of Diamond Bar was 5:38 minutes, slightly above the target response time. 62 1.1 Packet Pg. 257 Figure 3-3: Public Safety Services SU NSETCROSSINGRO Walnut O Walnut/Diamond Bar I o Sheriffs Station i n o Industry Metrolink Station n LYCOMING ST10 a e z O c� �y ��{Qv ,�OY'N SPpINGS DR QP Y`1 DR O CityHall( \ i 90 MOUNTAIN LAURA 4- 1A11,1" 01,9 w 'ti NOP OgF;fS I 09 2 RELIA PINE D/7 C S m 2 m o ,y Los Angeles County Fire Dept. t Station 119 UANYONRR, LOSANGELES w PPa COUNTY I� w / i L --------- it t. 1 1' 1 Firestone ' Scout Reservation O 0 w O R t b /---------- ----------- -------------0 ^FYI OFire Station Highways Minor Roads OPolice Station Ramps Water Features City Hall ---- Railroads — �1 City of Diamond Bar Major Roads Sphere of Influence GENERAL PLAN 1.1 City of Diam `//GH LAND VLY RD `_,,SING RD q\ Pomona 2y FO I J PGI EN yu iy ENA DR Los ngel s County \ Fire Dept.

ISO ratings range from one to ten, with one being the best and ten being no protection at all. Diamond Bar was given a rating of three in 2000, the most recent year available. Staffing and equipment inventory for the three fire stations in Diamond Bar are provided in Table 3-9. The County Fire Department has 12 staff members stationed in Diamond Bar, including three captains, three firefighter specialists, four firefighter/paramedics, and two firefighters. Each fire station is equipped with one fire engine. Station 119 contains a two -person paramedic squad. In terms of street design and requirements for new development, the Department requires a 32 - foot centerline turning radius. It also requires a minimum unobstructed width of 26 feet for buildings under 30 feet, and 28 feet for buildings more than 30 feet high or three stories. Table 3-9.

The City of Diamond Bar relies on Walnut Valley Water District (WVWD) to provide reliable water supplies throughout the city. Nearly all water supplies are imported due to a limited availability of local groundwater. Imported water supplies are expected to remain attainable for at least three years, and projected supplies are expected to meet projected demands from 2020 through 2040 under single dry -year and multiple dry -year conditions.45 Drought conditions will continue to strain water supply available to WVWD and the city as they do throughout southern California. Thus a "drought -proof' recycled water system is maintained for use by parks and school properties to relieve demand on the District's potable water system. WVWD is proactive in addressing water supply constraints and continues to invest in groundwater facilities. WATER SUPPLIES WVWD imports all potable water from the Metropolitan Water District of Southern California (MWD). WVWD currently has projects underway that will produce groundwater from the San Gabriel Basin, Central Basin, and Six Basins to supplement potable water supplies. A description of available water supplies is provided below. Imported Water MWD obtains surface water from the Colorado River and from Northern California via the Colorado River Aqueduct and the California Aqueduct respectively. WVWD purchases water through MWD's designated wholesale agency, the Three Valleys Municipal Water District (TVMWD). Imported water supply volumes are projected to increase through 2035 at the same rate as population growth, which is 0.7 percent as reported by SCAG.46 Groundwater WVWD currently operates six groundwater production facilities that supply the recycled water system. This groundwater is not potable as it contains high levels of total dissolved solids and nitrates. The following three projects will allow WVWD to produce potable groundwater, thereby reducing the need for imported water. The La Habra Heights County Water District Pipeline Project, completed in 2014, delivers up to 1,000 acre-feet of potable water per year from the Central Basin to WVWD. This project includes an inter -connection to the La Habra Heights County Water District system. The California Domestic Water Company Project consists of a new pipeline and pump station project that will connect to the California Domestic Water Company system. Annual deliveries to WVWD will be 2,500 acre-feet of potable water. Water stored in the Main San Gabriel Basin will 45 Metropolitan Water District of Southern California 2015 Urban Water Management Plan. 46 Southern California Association of Governments (SCAG), 2016-2040 RTP SCE Demographics and Growth Forecast, 2015. 66 1.1 Packet Pg. 261 Existing Conditions Report — Volume III, January 2017 Environmental Constraints and Opportunities; Public Facilities, Services, and Utilities supply potable water for this project which was approved on September 2015 and currently in the design stage. Production from Six Basins will supply WVWD with approximately 928 acre-feet of potable water per year upon completion of the Pomona Basin Regional Groundwater Project. This project includes reactivating an existing well and constructing one new well, and is expected to be complete in 2018. Recycled Water WVWD currently owns, operates, and maintains a recycled water system that provides irrigation water to customers throughout its service area, including the City of Diamond Bar. The County Sanitation District's Pomona Water Reclamation Plant supplies recycled water to WVWD for irrigating large landscape areas such as parks, golf courses, greenbelts, and school grounds. Future uses will generally fit these categories, with potential demands for toilet flushing in high-rise buildings and industrial use. Local groundwater supplies may also help WVWD expand the current recycled water system. This system is completely separate from the potable system and helps reduce potable water demand. During calendar year 2015, WVWD's recycled water system delivered 2,242 acre-feet of water, including 511 acre-feet to customers within the city. Approximately 170 existing potable water irrigation users (corresponding to approximately 1,050 acre-feet annually) throughout the city could be converted to recycled water use if the system is expanded. However, recycled water supplies are maxed out during peak summer months. Therefore, large-scale expansion of the system is not feasible until additional recycled water supplies become available. Future Water Projects The Cadiz Valley Water Conservation, Recovery and Storage Project will allow TVMWD to supply WVWD with water from a renewable aquifer in the eastern Mojave Desert. Approximately five percent of the aquifer's water will be pumped over the 50 -year life of the project. This will prevent loss of water to evaporation, provide a new water supply, and create a groundwater bank for Southern California water providers. This project is currently securing final approvals and no construction start date is available. WATER SYSTEM INFRASTRUCTURE WVWD's service area encompasses approximately 29 square miles of the San Gabriel Valley. The service area includes the City of Diamond Bar, portions of the cities of Walnut, West Covina, Pomona, and a section of unincorporated Rowland Heights. WVWD's service area is primarily residential, with most commercial and industrial uses located in the City of Industry. Potable Water WVWD potable water distribution and storage system consists of the following facilities: • 23 water reservoirs; • 9 pump stations; 1.1 67 Packet Pg. 262 Diamond Bar General Plan Update • 29 pressure regulating stations; • 238.6 miles of distribution and transmission pipeline; and • 4 connections for importing water. Eight pressure zones are required to provide adequate water pressure to all consumers. An overview of WVWD's facility conditions was not available, therefore a comprehensive evaluation may be required to properly assess those facilities in the city. Improvements and upgrades are in process, including the development of a disinfectant residual control system to enhance and maintain water quality. An emergency power program is in process that will ensure availability of potable water after emergencies or power outages. Recycled Water WVWD recycled water distribution and storage system consists of the following facilities: • 2 water reservoirs; • 2 pump stations; • 6 wells; and • 8.37 miles of distribution pipeline. Communities within WVWD's service area are supportive of efforts to expand the recycled water system. WVWD has funded installation of recycled water distribution mains and meters. Installation of new meters is required for all development projects that have a potential for recycled water use. WATER USE WVWD maintains 26,836 water meters throughout its service area, 95 percent of which are residential. Diamond Bar's potable water use since 1993 has ranged from 7,077 to 13,188 acre-feet per year. Water use has generally declined during this time despite a continual increase in the total number of accounts, as shown in Table 3-10. Historic data for recycled water is not available prior to 2010. However, usage is expected to increase through the 2035 system buildout, as shown in Table 3-11. 68 1.1 Packet Pg. 263 1.1 Existing Conditions Report — Volume 111, January 2017 Environmental Constraints and Opportunities; Public Facilities, Services, and Utilities Table 3-10: Historic and Projected Water Usage (Potable), City of Diamond Bar Total Water Usage Year Total Accounts (Acre -Feet per Year) 1993 11,772 12,681 1995 11,833 10,975 2000 11,971 13,188 2005 12,422 12,521 2010 12,426 9,260 2015 12,432 7,077 2020 (Projected) Not Available 8,281 2035 (Projected) Not Available 9,179 Source: Walnut Valley Water District.

WATER CONSERVATION Ordinance No. 06-09-07 was adopted by WVWD to establish progressive water reductions during drought conditions. This ordinance implemented a water shortage contingency plan describing five stages of action, each targeting a percent reduction in water use. Stages of action will be mandatory and are a function of MWD's water shortage allocation plan, as shown in Table 3-14. WVWD also established Demand Management Measures to enforce responsible water use. Wasteful consumption, including excessive runoff and washing hard or paved surfaces, is prohibited. Notified water users have five days to remedy any wasteful practices. Failure to comply may result in a disconnection of service. 70 Packet Pg. 265 1.1 Existing Conditions Report — Volume III, January 2017 Environmental Constraints and Opportunities; Public Facilities, Services, and Utilities Public outreach/information programs are also in effect that provide education and encouragement through newspapers, billing inserts, social media, signs, and community events. Similar outreach is conducted at schools, including in -class presentations and internship opportunities for high school students. Other incentives to conserve water include rebate programs for rain barrels and high - efficiency washing machines.

The Los Angeles County Public Works Department (LACPWD) provides operation and maintenance services on the local collection system, while Los Angeles County Sanitation District (LACSD) provides operation and maintenance services on the trunk sewers and wastewater treatment services. The city and surrounding areas fall under the LA County Sanitation District No. 21. The City is currently negotiating ownership and maintenance responsibilities for the local collection system with the LACPWD. The LACPWD maintains that the system is owned by the City and maintained by LACPWD; however, the City asserts that the system is both owned and maintained by LACPWD. While the system is generally in good order, as described below, there has not been an area -wide sewer study completed in the last 10 years that identifies all deficiencies within the City's sewage infrastructure system. As such, the City's Sewer System Management Plan (SSMP) audits were used to gather information about the existing system. SANITARY SEWER SYSTEM INFRASTRUCTURE The local collection system contains 11 pump stations and 162 miles of sewer mains within the city. According to City Staff, the local collection system is in good standing with no known major system deficiencies. Los Angeles County Public Works The City's local collection system is shown on Figure 3-4. The local system of sewer lines and pump stations feed two trunk sewer lines that convey wastewater to a LACSD treatment facility. The City has been completing systematic annual audits of the collection system, including closed-circuit television (CCTV) inspections of sewer lines, and manhole and pump station inspections. Any structural or maintenance deficiencies in the sewer system identified during the audit are reported 71 Packet Pg. 266 Diamond Bar General Plan Update with a recommended repair. In 2015, no sewer capacity issues were identified. However, the City regularly pumps wastewater at the intersection of Clear Creek Canyon Road and Diamond Bar Boulevard to overcome system deficiencies, which may warrant further investigation in the future. The City and LACPWD have been effective at keeping the number and total volume of sanitary system overflows (SSOs) within the city below the Statewide median, with only three SSOs reported in each of the last three years. In addition, the City rarely receives complaints from citizens regarding wastewater and SSO. The SSOs are typically related to debris, root intrusion, and/or fats/oil/grease causing the overflow issues. In addition, there are occasional SSOs related to pump station failures. Los Angeles County Sanitation District LACSD maintains two trunk sewer lines that originate south of SR -60 and west of SR -57. These lines convey wastewater to a County treatment facility outside city limits, also maintained by the LACSD. As new development occurs, the LACSD requires the new developments to annex into its service area for operation, maintenance, and treatment services. Service fees fund required upgrades to trunk sewer lines or treatment plant capacity. 3.6 Stormwater and Flood Control Facilities The Los Angeles County Flood Control District (LACFCD) owns and maintains all major flood control channels in Diamond Bar. In addition, a majority of the storm drain system within the city was formally transferred through resolution to LACFCD, which maintains complete ownership and maintenance of the system. However, some portions of the existing system were never transferred to LACFCD. This has resulted in ownership disputes with LACPWD, who provides maintenance only for said portions and makes no claims toward ownership. Stormwater quality is the responsibility of the City. While the system is generally in good order, a master drainage plan, identifying all deficiencies within the City's drainage infrastructure system, has not been completed. STORM DRAINAGE SYSTEM INFRASTRUCTURE The city's storm drain system can be seen on Figure 3-5. The local storm drain system generally consists of a series of catch basins and reinforced concrete pipes/boxes that convey stormwater runoff to other major flood control channels. The local storm drain system conveys water to one of three major flood control channels, the San Jose Creek, Diamond Bar Creek, and the Brea Canyon Channel. These major flood control channels are owned and maintained by the LACFCD. According to City staff, the local storm drain system is in good standing with no known major system deficiencies. 72 1.1 Packet Pg. 267 Figure 3-4: Existing Sanitary Sewer System Walnut Metrolink Station LYCOMINGST _ 1 LOSANGELES COUNTY a Diamond Bar Sewer Main Lines Los Angeles County Sanitation District Trunk Lines Highways Ramps Industry r 9Z V SELLAPINED G `v�Fzgp//'/gam A ilk � �(i o �* w J P(pNS / `.tee �O�pePP o� � 0 1 SNEPS ST 1 1 �r I I I 1 1 I I 1 I I I 1 Major Roads Local Roads - Railroads Water Features City of Diamond Bar L Sphere of Influence County Boundary GENERAL PLAN 1.1 City of Diam Pomona SAN BERNARDINO COUNTY Source: City of Diamond Bar 2016;TKE Engineering, o 0.375 0.75------------------ 1.5 DY 2016; Dyett & Bhatia, 2016 MILES urban Packet Pg. 268 Figure 3-5: Existing Storm Drain System Walnut a¢ Industry o e pa Metrolink 5 k Station t �' T � do / 80S DR i y�S ��Eaa m �q j- MO IN L RE[ N); 9Pp . 0 BELIA PINE DB ��NE&0 R / 9 Nps �q� oy �I 0 �^ NRIDC v LOSANGELESe COUNTY Ie r. w I 1 1 ENS Sl o� 1 I r \A 1 1 1 I 1 1 I I 1 I � ------------------------------------------------------------------------------ -- A PrZA p,,,NG RD e GENERALPLAN City of Diam Pomona I I S 2 I r----------------� SAN BERNARDINO COUNTY Storm Mains Open Channel Highways Ramps Major Roads Local Roads — Railroads Water Features L_—_�1 City of Diamond Bar Sphere of Influence County Boundary 0 0.375 0.75 I.s DY Source: City of Diamond Bar 2016; Dyett & Bhatia, 2016 MILES Urban Packet Pg. 269 1.1 Packet Pg. 270 DYETT & BHATIA Urban and Regional Planners 755 Sansome Street, Suite 400 San Francisco, California 94111 ®415 956 4300 8415 956 7315 www.dyettandbhatia.com DIAMOND BAR GENERAL PLAN UPDATE 1.1 Stakeholder Interviews Report November 2016 Prepared for City of Diamond Bar by DYETT & BHATIA Urban and Regional Planners Packet Pg. 272 1.1 Packet Pg. 273 DIAMOND BAR GENERAL PLAN UPDATE Stakeholder Interviews Report November 2016 Prcparcd for City of Diamond Bar by DYETT & BHATIA Urban and Regional Planners 1.1 Packet Pg. 274 1.1 Packet Pg. 275 1.1 Table of Contents Introduction.................................................................................................................. 1.1 Background on the Diamond Bar General Plan Update.............................................................1 1.2 Stakeholder Interviews Purpose and Process...............................................................................2 1.3 Report Organization...........................................................................................................................2 2 Major Themes.............................................................................................................. 3 2.1 Primary Topics Addressed.................................................................................................................3 2.2 Other Topics Addressed................................................................................................................ 1 1 3 Next Steps.................................................................................................................. 13 Appendix A: Stakeholders Interviewed......................................................................... 14 Appendix B: Stakeholder Interviews Prompts/ Guiding Questions ........................... 15 Packet Pg. 276 Diamond Bar General Plan Update This page intentionally left blank. 1.1 Packet Pg. 277 Introduction I.I Background on the Diamond Bar General Plan Update The City of Diamond Bar's original General Plan was written in 1995, at which time the City laid out goals and strategies to manage development while maintaining a country living environment. In the intervening years, the City has accomplished many of the goals established in the original plan, though recent years have presented new opportunities and challenges. Regional growth has accelerated, substantially impacting the city due to its location at the interchange of two major freeways. While Diamond Bar's population growth has been modest, the city has experienced significant shifts in its demographics. In recognition of its changed context, the City began the process in 2016 to update its General Plan, a multi-year endeavor that will provide residents with an opportunity to explore new ideas and shape the city's future by putting policies in place to guide development and investment for the next twenty years. The General Plan is a policy document that implements the vision of the community. Therefore, public participation is an important part of the process of shaping the Plan. Opportunities for public input have been designed to allow the planning team to learn directly from city residents, business and property owners, and other community members about their needs and values, as well as to allow the public to provide feedback throughout the phases of the planning process. Community members and interested parties are invited to participate in the process and stay informed in many ways, including: • Stakeholder interviews; • Community workshops; • City Council and Planning Commission meetings; • General Plan Advisory Committee (GPAC) meetings; • Online survey; • Newsletters; • Reviewing and commenting on draft documents; • Comments via e-mail; and • Project website at http://www.diamondbargp.com/. 1.1 Packet Pg. 278 1.1 Diamond Bar General Plan Update 1.2 Stakeholder Interviews Purpose and Process The General Plan Update work program is designed to identify issues, opportunities, and challenges early on in the planning process to enable the planning team to reflect on these issues in the preparation of alternative planning scenarios. The lead consultants, Dyett & Bhatia, conducted in- person interviews on September 28 and 29, 2016 with a cross-section of stakeholders identified by City staff working with Arellano Associates, a subconsultant assisting with community outreach. Further community input will be gathered through a community visioning workshop, "pop-up" booths at various locations and events, and a survey distributed online as well as at various community events. A total of 23 stakeholders participated in the interview process. The stakeholders represented a diverse range of local and regional interests including: real estate professionals, local developers and commercial property owners, service organizations, major employers, active community members, former City Council members, school district administrators, small business owners, and youth groups. Many of the interviewees were residents of Diamond Bar as well, though some had business in the city but lived elsewhere. A complete list of stakeholders interviewed can be found in Appendix A. The interviews were conducted in-person in groups of one to four people, as well as one interview conducted over the phone on September 16. Most sessions lasted approximately one hour. The structure was loosely guided by an initial set of questions used as prompts; however, responses were "free form." Stakeholders were given the opportunity to provide their viewpoints on issues of significance, Diamond Bar's future, general planning concerns, and other topics of specific interest. The "prompt" questions used in the interviews are included in Appendix B. The varying points of view offered by individual and group stakeholders are recognized in this report. To understand perspectives of the general Diamond Bar community, the City will be undertaking additional outreach efforts that are targeted at and open to the community at large. 1.3 Report Organization Chapter 2 presents the comments from the stakeholder interviews by topic. The topics were identified subsequent to the interviews, based on themes that emerged across a wide cross-section of stakeholder interviews. The report concludes with information about how this input will be used during the next steps of the General Plan Update process. Appendix A includes a list of those interviewed and Appendix B includes the questions asked at the interviews. It is important to recognize that the issues presented in this paper may not necessarily be representative of the community at large or a comprehensive assessment of opportunities and challenges faced in the city. While the stakeholders represented a diverse spectrum of the Diamond Bar community, no sampling techniques were employed in selecting the stakeholders, and consequently, the results cannot be generalized as the sentiments of the population at large. This report presents the perceptions and opinions of stakeholders interviewed; it does not represent the perspective of the consultant team or the City of Diamond Bar. Packet Pg. 279 1.1 Stakeholder Interviews Report 2 Major Themes During the stakeholder interviews, several themes were repeatedly identified. Major issues identified by multiple stakeholders are listed below for quick reference and explained further in Sections 2.1 and 2.2. Diamond Bar' greatest assets were identified as: • Good schools • Safe community • Parks and open space Challenges identified as most important to be addressed were: • Transportation • Identity/community • Retail/entertainment • Housing growth • Multiple school districts • Green space resources Other recurring themes included: • Changing demographics • Community facilities • Fiscal responsibility • Office sector • Jobs and labor force 2.1 Primary Topics Addressed TRANSPORTATION Traffic Congestion Traffic congestion arose in almost every stakeholder interview as the primary overall concern in the city, described as "horrible" and "a real tragedy." One stakeholder said that increasing traffic will change the face of Diamond Bar so that we may not be able to recognize it. 3 Packet Pg. 280 1.1 Diamond Bar General Plan Update Stakeholders attributed much of the traffic to commuters flowing through the community from outside to access the freeways. Multiple stakeholders pointed to the extension of Grand Avenue through to Chino Hills as an inflection point for Diamond Bar's traffic problems, which angered many residents once commuters from the east began taking Grand Avenue to access the freeways. Residents pointed to Diamond Bar Boulevard as a particularly congested thoroughfare, especially when schools let out in the afternoon. The stakeholder interviews point to a mismatch of jobs and housing as a contributor to Diamond Bar's traffic congestion. As discussed in more detail in Section 2.2, Diamond Bar is a bedroom community that provides relatively more housing than jobs, resulting in the need for residents to commute out of the city for work. In addition, conversations with the city's major employers revealed that very few of their workers live in Diamond Bar, which results in many workers commuting into the city as well. Several stakeholders, including community service organizations, major employers, and small business owners, expressed a desire for traffic light synchronization. Some stakeholders mentioned the proposed Tonner Canyon bypass as a possible traffic alleviation measure, though former City Council members also remarked that a bypass may not help the city, as it would divert visitors away from the city's main commercial centers. Others believed that the commuters from outside of the city never stop to do any business in Diamond Bar anyway, and therefore a bypass would not negatively impact local businesses. The planned construction of a new freeway onramp at the former Honda site was also discussed by a few stakeholders as a potential means of relieving congestion, though real estate professionals interviewed indicated that these plans have stalled. One real estate broker believed that, without a right-hand turn land at the Honda site, taking a left-hand turn onto the freeway will be a "nightmare" once the outlet mall is built at Grand Crossing in the City of Industry. Traffic congestion was the most common reason given by stakeholders that additional development should be avoided, including non-residential development. Senior Mobility Apart from congestion issues, multiple stakeholders for senior groups mentioned that the City has reduced the radius for its Dial -A -Cab service, leaving many seniors without transportation options, including for medical service. Transit and Active Transportation There was very little discussion of public transit and non -motorized transportation. Noticeably absent from most stakeholder interviews was discussion of the Metrolink station. When it was brought up by the interviewers, several stakeholders were not even aware that the station was within Diamond Bar at all, or else it was simply not a subject of interest. One stakeholder said that the Metrolink is surrounded by the City of Industry, which is why people often overlook it. The major employers interviewed said that even though the great majority of their employees live outside of Diamond Bar, very few employees commute by Metrolink. Packet Pg. 281 1.1 Stakeholder Interviews Report The spokesperson for DB4YOUTH commented that since Diamond Ranch High School lacks its own bus system, some students will take the public bus in the morning and get rides from parents after school, while other students have made their own off road trails, which the high school has not discouraged. While some students walk long distances to school, the youth representative said very few students commute by bicycle. IDENTITY/COMMUNITY There was disagreement among stakeholders on the degree to which Diamond Bar feels like a unique community. One stakeholder characterized Diamond Bar as lacking an identity, and others described the city as "dead." However, some residents pointed to the parks, particularly Pantera Park, as places that build a strong sense of shared community, especially where people can bring their dogs and meet each other. The schools also serve to bring families together in the shared interests of their children. An educational stakeholder recounted that Whittier used to be "dead", but was reinvigorated through its connection with Whittier College, and now feels like a college town. Such a precedent could be instructive for Diamond Bar, which could embrace nearby institutions such as Cal Poly Pomona. Other ideas for building community included the addition of a cultural center, as well as places for kids to engage in activities outside of school. Diamond Bar does not have a traditional central gathering place. The intersection of Grand Avenue and Diamond Bar Boulevard was discussed by former City Council members as being a natural center of town, though there was disagreement as to whether the site was big enough for focused downtown development. They believed that traffic in that intersection is mostly imported from outside of the city, and they pointed to the challenge of creating commercial development there that would make people want to stop to dine and shop, rather than continuing to drive east and south. RETAIL/ENTERTAINMENT Many stakeholders complained that there were not enough places to shop locally, forcing residents to go to places like Chino Hills, Brea, and Puente Hills to fulfill their shopping and entertainment needs. While some stakeholders expressed a desire for more restaurants and shopping opportunities, one stakeholder pointed out that there are many vacant storefronts in the city, including the Kmart site that has long been empty. Former City Council members agreed that residents are often not aware of what retail options are on the other side of town, and continue to shop elsewhere. This results in many local businesses closing, and has inspired the city to publish a restaurant guide to promote what currently exists. Commercial property owners interviewed said that certain demographics cater to certain commercial tenancies, and building higher density housing that is more affordable than the current stock would bring the kind of buyer that would help support tenants in the city's commercial centers. Many stakeholders spoke of a need for more shopping variety. Some stakeholders spoke of the reluctance of white residents to eat at Diamond Bar's restaurants that are mostly Asian, while other stakeholders mentioned a need for high-end dining, the lack of which is driving many residents out Packet Pg. 282 Diamond Bar General Plan Update as far as Pasadena to dine. A stakeholder representing seniors mentioned the city needs stores like Whole Foods and Trader Joe's, as people are becoming more health conscious. A need for variety in retail options was echoed by a County representative, as well as one of the city's major employers, who said that employees would like more options for entertaining customers. He also said that most of their employees living outside of Diamond Bar go straight home after work, though they might stay around in the evening if there were more events and attractions. The DB4YOUTH spokesperson reported that teenagers wanted to see a movie theater in the city, either at the Kmart site or elsewhere. This desire was echoed by a stakeholder representing seniors, who was sad to see the closure of the city's last cinema. The City's actions relating to shopping centers were the subject of complaints from both business owners and commercial property owners. One commercial property owner believed the allowable uses in commercial zoning districts are too restrictive. They reported that in one instance, the City called prospective tenants of one shopping center to discourage them, as higher end tenants were desired; however, the City was unwilling to allow for the sort of high density, mixed-use development that would attract higher caliber tenants. A former City Council member said that the City did not take the opportunity for mixed-use development when a supermarket closed across from Willow Heights. A longtime business owner complained that when a property owner bought much of the property near the Kmart in bankruptcy, the City did little to help the tenants whose leases were invalidated. He believed that, along with the continued vacancy of properties like the Kmart site, hurts the perception of the city by business owners. One pair of business owners mentioned that the shopping center at Diamond Bar Boulevard and Grand Avenue is not cohesive, that every corner looks different and none of them are attractive. They also attributed the scarcity of businesses in Diamond Bar to residents having so much of their money tied up in their homes, and that when they do spend money, they are used to going outside of Diamond Bar, often shopping at warehouse clubs or online. Grand Crossing/Golf Course One former City Council member believed that the Grand Crossing development in City of Industry, which will include an outlet mall in addition to warehouse space, will limit Diamond Bar's opportunities for new retail development and may threaten existing shopping centers, such as the Target. The redevelopment of the golf course as a shopping center was discussed by several stakeholders, though it was acknowledged that the Grand Crossing hurts the feasibility of any such proposal. Honda Site Redevelopment There was some discussion among real estate professionals about the potential at the Honda site for a hotel, with perhaps some residential use in addition. Brokers pointed to the Flair Spectrum project in El Monte as precedent, which will combine hotel, residential, and retail development at the site of another former auto dealership. 6 1.1 Packet Pg. 283 1.1 Stakeholder Interviews Report :1 *19111► 10 The stakeholder interviews addressed many aspects of housing in Diamond Bar. Housing prices are above state and county averages, and buyers can find newer homes for less in Chino Hills, though multiple stakeholders mentioned that Diamond Bar is still about as affordable as you can find this far north in the region. According to a real estate broker, a lot of the new buyers are Chinese investors, who find homes in Diamond Bar much more affordable than comparable properties China. A stakeholder from a community service organization said Chinese investors will often flip houses in Diamond Bar, some of which are home to "vacation families" who will live in a house for only a few weeks a year. Housing density was a polarizing topic among community stakeholders. Developers and property owners believe the city is housing deficient, particularly in the kind of higher density and mixed- use housing products that would draw younger people to live in Diamond Bar. One property owner believed that underperforming shopping centers constitute the best opportunity for new housing, which can provide a base to support shopping center tenants through a mixed-use development. One major employer, whose employees mostly live outside of Diamond Bar, said his employees generally think they cannot afford to live in Diamond Bar because of its perception as an unaffordable place to live. If there were more condominiums available, he believes his employees would be more inclined to look for housing in Diamond Bar. Another stakeholder representing community service organizations thought that building more condominiums would be good in that it would bring young people while at the same time saving land. Other residents who were interviewed felt very differently about housing density, believing that housing should be limited in order to prevent further traffic congestion, which would make the city "unlivable." Some were opposed to the aesthetics of multifamily housing and mixed-use development, and thought that it detracted from the "country living" aesthetic. Others voiced concerns about the impact of housing density on parking. The youth group also said they would rather not have high rise housing. Willow Heights, one of the city's newest housing developments that contains single-family homes as well as attached and detached townhomes, was a common touchpoint for the issue of housing density in Diamond Bar. One property owner believed that Willow Heights represented a shift in attitudes, as such housing density would not have been possible 10 years ago. Some stakeholders that were generally opposed to higher densities in Diamond Bar were accepting of Willow Heights, though one stakeholder characterized it as a "prison" that has "ruined" Diamond Bar. Multiple stakeholders mentioned that if the golf course redevelops, it would be difficult to gain acceptance for multifamily housing at that site, partly because residents would want to see more sports fields and other uses. Diamond Bar was often mentioned as having a lot of multigenerational households. This was explained as being a result of cultural as well as economic factors. One YMCA representative, who noted that a lot of families at the Diamond Bar YMCA are on financial assistance, found that a lot of adults in Diamond Bar will move back in with their parents when they are in their thirties or older, even when they have their own kids, because they cannot afford to live on their own. This results in larger households and more cars per household. The growing presence of seniors in Packet Pg. 284 1.1 Diamond Bar General Plan Update Diamond Bar, both in multigenerational households and other household types, has made downstairs bedrooms more desirable. According to former City Council members, as well as the Pomona Unified School District (PUSD) Superintendent, the City has designated a portion of the Tres Hermanos area for affordable housing in order to meet its Regional Housing Need Allocation, which would concentrate lower income residents on the city's outskirts. There was skepticism as to whether any affordable housing would actually be built there, as stakeholders believed it would be unusual to build lower income housing in remote hillside areas. MULTIPLE SCHOOL DISTRICTS When asked about Diamond Bar's strengths, almost every stakeholder interviewed mentioned the high quality of the schools in the district. Walnut Valley Unified School District (WVUSD) is considered one of the best school districts in the state, and it is considered by real estate professionals to be the biggest attracting factor for residential real estate. Property owners believe that WVUSD's high performance is the primary driver for the influx of Chinese families to Diamond Bar. PUSD schools within Diamond Bar are also considered to be very good, though the common perception is that they are not on the same level as WVUSD, which has led to higher home prices in the south. Even Pantera Elementary, which has the highest test scores in PUSD, still loses many students who transfer to Lorbeer in WVUSD. Families in Diamond Bar have high expectations of their schools, which leads to delivery of a high standard product. The split between the school districts was often cited as a source of frustration, even though those that point out the split also acknowledge that the City has little agency to address it. One former City Council member recounted that in the late 1970s, there was a vote to annex north Diamond Bar into WVUSD that did not pass. The two districts are considered by residents to have different philosophies and values, and the split within the city is a divisive force. The north side of town is considered less desirable than the south side, according to real estate professionals, because of the difference in school districts. One real estate agent spoke of cases where families mistakenly bought into the north side of town because they did not realize where the school district boundaries lay. A community service organization spokesperson pointed out that the two districts do not take the same days off, which makes it difficult for youth -oriented service organizations to serve everyone in town. The PUSD Superintendent stated that declining enrollment at multiple schools threatens their ability to stay open in the future. If enrollment trends continue, he thinks that Diamond Point Elementary could be repurposed for another use, such as a performing arts theater. However, one community service stakeholder mentioned the cautionary tale of La Mirada, which sold some of its schools after a wave of growth, but suffered for it when a new wave of families arrived. PUSD also owns 31 acres below Diamond Ranch High, for which the District has not yet determined a use. The location is valuable, the Superintendent says, but it would be difficult to build on given the grading issues, and the District may decide to sell the property. The Assistant Superintendent for WVUSD said that even though WVUSD is high performing, it is one of the most underfunded districts in the state based on the Local Control Funding Formula, and they are exploring partnerships to better secure their finances. Packet Pg. 285 1.1 Stakeholder Interviews Report District of Choice The potential end of the District of Choice program is a major source of concern among residents, which allows students from outside of Diamond Bar to attend WVUSD schools without seeking permission of their home districts. WVUSD's representative said that the program's end would likely mean school closures and numerous layoffs. On the other hand, PUSD's representative believed the program's end would boost their enrollment. The youth group worried that housing prices and demand might diminish with the end of the program. Com] it 4 4 2 &I J_[a] 410 *16111 Zia] �► While community stakeholders found strengths in the city's parks and open spaces, they pointed out several areas with room for improvement. Sports Fields Many stakeholders voiced concerns over limited access to sports fields. The city has a joint use agreement with Lorbeer Middle School, whereby the city manages and maintains the sports fields in exchange for use of the fields outside of school hours, but the arrangement can result in confusion and disappointment over the availability schedule for local sports organizations. Many Diamond Bar residents, according to a county representative, are concerned with supporting local little leagues and other sports organizations that have been operating their own properties and maintaining them. However, one stakeholder was concerned that the Pony Fields was using up a lot of prime green space for a small number of children, and could be better utilized if it was converted to public park space. The Lanterman Developmental Center was also brought up more than once as a possible site for future sports fields, with one former City Council member believing that Cal Poly Pomona, which now owns the site, might be open to leasing part of the site to the City of Diamond Bar at an affordable rate. Parks/Trails Some of the parks received high marks from residents, particularly Pantera Park, which benefitted from a committee of residents who took control of what the park should be. Pantera Park, however, is not perceived to be easily accessible to many residents. Other parks, such as the city's newest park by the Willow Heights development, was regarded by some residents as a bit of an "afterthought" in terms of its design. A couple of stakeholders also mentioned that it can be challenging to find park space in which to gather outside of sporting activities, with it often being necessary to book picnic space in advance at several city parks. While Diamond Bar residents would like to see more parks, a County representative said that residents have been opposed to a County proposition to raise a tax for parks, as there is no county park within easy access of Diamond Bar. Several stakeholders pointed to the trail system in Diamond Bar as a big success, with people using the trails at all hours of the day. One stakeholder suggested that expansion of the trail system could help improve community safety by getting more people outside in different parts of town. A youth 9 Packet Pg. 286 1.1 Diamond Bar General Plan Update representative also mentioned that students at Diamond Ranch High will create their own trails to walk to school. Tres Hermanos Several residents viewed Tres Hermanos ranch as an important open space area between Diamond Bar and Chino Hills that should remain undeveloped, with one stakeholder bringing up that it is an important reminder of the city's history as a ranch. The youth group wanted to leave the land undisturbed so people have open space to visit, rather than allowing it to become "wall-to-wall" buildings. Past City Council members said that the City of Industry, whose dissolved redevelopment agency owns most of Tres Hermanos, has considered for many years putting a reservoir on the land. Since none of the Tres Hermanos area is within the City of Industry, the City can only use the land for a municipal use, such as a reservoir. It was reported soon after the stakeholder interviews that a County oversight board rejected the City's bid to buy the land at a reduced price with the intention to build a reservoir. As mentioned earlier, Diamond Bar has also designated a portion of the Tres Hermanos site as a location for affordable housing, with high density residential zoning. Golf Course While several stakeholders mentioned their appreciation for the trail system as well as some of the parks in the city, the County -owned golf course was not complimented to nearly the same degree, and only became the subject of conversation in discussions about its relocation and redevelopment. While several potential uses were discussed, former City Council members thought residents would want any redevelopment to include sports fields. However, one real estate professional mentioned that the golf course is still highly prized by the County Board of Supervisors, and a former City Council member spoke of significant opposition to any plans to redevelop the golf course from residents living nearby. Any plans to redevelop the golf course would require the City to provide a matching property for the County elsewhere, which was the subject of much discussion. Several stakeholders voiced their support for a past proposal that would have relocated the golf course to a property owned by AERA Energy in Puente Hills, which is outside of the Diamond Bar Sphere of Influence, but adjacent to it. Another stakeholder who works for the County mentioned past plans that would have relocated the golf course to Tres Hermanos, as well as an idea still being considered that would involve the City purchasing the privately -owned Royal Vista golf course in Rowland Heights and transferring ownership to the County. While there is purported interest from at least some portion of the three Royal Vista owners in selling the property, Rowland Heights residents have fought back multiple development proposals for the site, and so it is believed that the County would be very amenable to a transfer of ownership to the County that would keep the property as a golf course. 10 Packet Pg. 287 1.1 Stakeholder Interviews Report 2.2 Other Topics Addressed CHANGING DEMOGRAPHICS Many stakeholders highlighted the shift in Diamond Bar to a majority Asian population, which has led to more local businesses being Asian -owned. A stakeholder for a Chinese senior group points out that the Chinese residents should be involved in the larger community more, as they need expert voices who know what's happening in the city and can communicate with the rest of the Chinese community. While the population makeup has changed, several stakeholders mentioned that people who move to Diamond Bar tend to stay long-term, building neighborhood stability. COMMUNITY FACILITIES Several community facilities in Diamond Bar were the subject of high praise by stakeholders. The facility that is home to City Hall and the County library branch received high praise, though it was mentioned that the library is in a location that can be hard for kids to access. The Diamond Bar Center was also the subject of several compliments, though there is a perception that it is to some degree a victim of its own success, as high demand from inside and outside the community for weddings and conferences has resulted in the facility often being booked years in advance. There were mixed reviews on the city's senior facilities. One stakeholder, believing that Diamond Bar is an excellent place for seniors, said that the city's three Chinese senior clubs receive benefits from the city and nice locations for meetings. However, another stakeholder stated a desire to see a dedicated senior center within Diamond Bar to bring the city on par with the facilities offered in nearby communities. Currently, multiple senior groups share space in Diamond Bar Center, and an interest was expressed in having a dedicated space that would serve meals and provide an activity center where seniors can spend time with each other and have access to services. One stakeholder believed that the land near the Diamond Bar Center that was to be dedicated as a library branch would be a good location for a senior center. DB4YOUTH, a community service group of primarily teenagers, also expressed a desire for a dedicated teen center. IJPrel_10il*11.1ZP111•1114k Multiple stakeholders, including a nonresident working for the County, acknowledged that the City has been quite fiscally responsible, which enabled the purchase of the City Hall facility. A real estate broker said that Diamond Bar is not in need of the same kind of social services as other communities; it is a city where self-reliant people take care of their own needs. OFFICE SECTOR According to real estate professionals, the bulk of all office space and professional employment in Diamond Bar is concentrated in the Gateway Corporate Center, which hosts many Fortune 500 companies. Many Asian -owned businesses also lease office space in Diamond Bar, who tend to commute very short distances, unlike the employees of the larger companies based in the city. A representative from the Southern California Air Quality Management District (AQMD) reported II Packet Pg. 288 1.1 Diamond Bar General Plan Update that only 50 of their approximately 700 employees have a Diamond Bar home address, while a Graybar representative said that not more than five of their 125-140 employees live in the city. Altogether, one real estate professional believed about half of their office tenants in Diamond Bar commute in from outside. Office brokers interviewed said that office demand decreases substantially with distance from the freeway. While it is more expensive to lease office space in Diamond Bar than in some other areas, the renewal rates are very high, about 85 percent. In terms of the office market, Diamond Bar is often considered together with the City of Industry as part of a larger Asian American finance center. Graybar's representative said his company moved to Diamond Bar when they decided to house their sales operations and warehousing operations separately. They have been happy with the relocation to the Gateway Corporate Center, which provides easy highway access. As with an increasing number of companies, he said that it is easier for Graybar to recruit better sales talent in a premium office environment than in an industrial area. At the same time, however, the proximity of their location to nearby industrial/warehousing space is very appealing, and he sees this being a substantial draw for other companies that would like to house their sales and warehousing arms within easy access of each other, but not in the same location. Community Relations Graybar felt that they had a great business relationship with the City, and the company's managers feel appreciated by the City. The mayor has come to meet with them and asked what they'd like to see. City staff was also good at making introductions and went out of their way to fast track the processes of obtaining building permits and licenses. The representative from AQMD also spoke of having a good relationship with the City. The City, who used to lease space in the AQMD building, operates a daycare facility on the AQMD premises, and still holds a lot of their meetings at AQMD facilities, including City Council, American Youth Soccer Organization, and Parent, Teacher, & Student Association. AQMD did express that the City should be helping to implement energy efficiency programs for residencies and businesses, even if just to send mailings letting people know what state and federal programs are available. JOBS AND LABOR While several stakeholders characterized Diamond Bar as a bedroom community, connoting a place where people sleep as opposed to where they work during the daytime, employment was not a major topic of conversation during the interviews or of seeming concern. In contrast, the PUSD Superintendent said that the City of Pomona, when creating its General Plan, wanted to create warehouse and distribution centers in order to create lower income jobs, which was not a priority in Diamond Bar. One real estate professional did talk about the positive reputation of the labor force, which tends to be well educated given the proximity to local institutions of higher learning. The spokesperson for the youth group said that besides the City's Parks and Recreation Department, which provides summer job opportunities, there are very few other jobs for youth besides pizza restaurants and the like. 12 Packet Pg. 289 1.1 Stakeholder Interviews Report 3 Next Steps The input gathered during the stakeholder interviews will be used in subsequent phases of the General Plan Update process. The first-hand knowledge and experiences of the stakeholders will be invaluable in creating a new Plan that reflects the community's collective goals and visions. After carefully reviewing information shared by the stakeholders; an assessment of the city's opportunities and challenges; and general public input from the community workshops, the survey, GPAC meetings, and City Council and Planning Commission meetings, the planning team will prepare alternative land use and transportation planning scenarios and review them with the community. A Preferred Plan will be prepared, and following City Council endorsement, draft planning documents will be prepared and reviewed with the community. 13 Packet Pg. 290 1.1 Diamond Bar General Plan Update Appendix A: Stakeholders Interviewed Stakeholder filiation Affiliation Nefali Cortez Broker Associate Denise Coury Office Manager, Lakeview Village Corporation Ron Everett Past City Council Member John Forbing Past City Council Member Kris Georgeson Maple Hill YMCA Brian Hegarty Manager of Branch Operations, Graybar Electric Ron Heim Executive Director, Cushman Wakefield Michael Hodson Assistant Superintendent, Walnut Valley Unified School District Mark Hopper Pastor, First EV Free Church Amanda Jahanvash Studio Director, Red Dragon Karate Sushma Kashyap President, Sunshine Seniors Association Stefanie Koslosky Regional Manager, Lakeview Village Corporation Nell Lackpour President, Diamond Bar Senior Citizens Club Richard Martinez Superintendent, Pomona Unified School District Alison Meyers Community Services Coordinator, D134YOUTH Shihan Mohamad Owner/Master Instructor, Red Dragon Karate Jahanvash Mark Rogers Principal, TRG Land Inc (Hillside Planning & Design) Joseph Ruzicka Walnut Valley Rotary Club Stephen Saunders Associate, Cushman Wakefield Jack Tanaka Past City Council Member Angie Valenzuela Staff of Los Angeles County Supervisor Don Kanabe Jill Whynot Chief Operating Officer, South Coast Air Quality Management District Harry Wu Owner, Doubletree by Hilton Claremont 14 Packet Pg. 291 1.1 Stakeholder Interviews Report Appendix B: Stakeholder Interviews Prompts/ Guiding Questions 1.

The General Plan update provides a unique and important opportunity for community members to participate in guiding the city’s future. The updated General Plan will articulate a long-term vision for Diamond Bar and outline policies and programs to realize this vision. For more information on the General Plan Update process, please visit: www.diamondbargp.com. A variety of outreach activities have been completed or are underway to ensure that the General Plan Update reflects the community’s most important values and priorities. The initial phase of outreach includes stakeholder interviews, a community workshop, “pop-up” booths at various locations and events, a survey distributed online as well as at the pop-up booths, and the General Plan Update website. Concurrent with community outreach, the consultant team is researching existing conditions to prepare an Existing Conditions Report on key planning issues. This report summarizes input from the first community workshop, which focused on exploring community members’ visions for the future of Diamond Bar and major issues related to various aspects of life in Diamond Bar. This summary report, along with analysis of the other community feedback and the Existing Conditions Report, will serve as a valuable reference to guide City staff, the Planning Commission, the City Council, the consultant team, and others in formulating land use and transportation alternatives and the policy framework for the updated General Plan. 1.1 Workshop Format and Organization The first community workshop was held on November 9, 2016 from 6:30 to 8:30 p.m. at the Diamond Bar Community Center. The objectives of the workshop were to: • Explore community members’ perspectives on the long-range vision for Diamond Bar; • Obtain input from community members on major planning issues to be addressed during the General Plan Update; and • Identify common visions and themes for Diamond Bar. Around 80 community members attended the workshop. Members of the General Plan Advisory Committee (GPAC), Planning Commission, City Council, and staff were also in attendance but observed only, rather than participate in the workshop activities (with one exception: one GPAC did actively participate). The City provided interpretation services for those needing Mandarin, Korean, and American Sign Language translation. The workshop agenda is summarized below and included as Appendix A. 1.1 Packet Pg. 302 1.1 Diamond Bar General Plan Update WELCOME AND BACKGROUND The workshop began with a welcome from City staff. Consulting planner Sophie Martin followed with an introductory presentation on the purpose, scope, and schedule of the General Plan Update. The slides from the presentation are included in Appendix B. ACTIVITY #1 — PLANNING ISSUES "POP QUIZ" In the first activity, residents were given "post -it" notes and pens at each table. Participants were asked to provide quick written responses to nine questions pertaining to Diamond Bar's future. After finishing their quick responses, attendees posted their post -it notes on exhibits along the wall of the room. ACTIVITY #2 — 2040 VISION FOR DIAMOND BAR In the second activity, participants sat in small groups of approximately six to eight around nine tables. Participants were told to imagine that a reporter has visited Diamond Bar in the year 2040 to write a cover story on the City's extraordinary accomplishments and were asked to write and illustrate what they thought the headline would be using mock covers for a "special edition" of a magazine provided at each table. Participants shared their covers and their visions with their small group, and then a representative from each table reported out the main themes and highlights to all of the workshop participants. Appendix D provides a sample of these imagined covers and Appendix E includes a transcription of all of the covers with notes from the report -outs and written comments provided by participants. 1VA:L1all' Consulting planner Sophie Martin concluded the workshop, drew raffle tickets for a variety of small prizes, and invited participants to fill out a quick feedback form. Most of the written comments received were about the workshop itself, however some written comments were about issues related to the General Plan Update and are included in Appendix F. Packet Pg. 303 Report on Community Workshop #1 3 2 Planning Issues and Community Vision As noted in the Introduction, the first community workshop included two activities and a small group discussion of key issues and the desired vision for Diamond Bar. Highlights of the activities and discussions are summarized below, followed by a discussion of themes that emerged. The full transcription of results is included in Appendix C. 2.1 Activity #1: Planning Issues Activity #1’s nine questions were posed as a warm-up exercise to explore what planning issues Diamond Bar is facing today and would be important to the General Plan Update. Answers were synthesized and summarized to reveal broader patterns of responses. The percentages below refer to the percent of respondents that named the given subject in their response to a question. In many cases, participants gave multiple responses or did not fully answer a question, thus totals may not add up. IDENTITY AND VISION Three questions were asked that addressed the identity of Diamond Bar and explored the vision for the city’s future development, and ways that the General Plan could help achieve this vision. 1. What word do you think best defines Diamond Bar? The most common responses were “community” and “country living,” followed by “family” and “quiet.” Diamond Bar’s traffic issues were the only source of negative word connotations, which included “congested,” “over crowded,” and “gridlock.” Multiple participants described the city as a “bedroom community,” which was alternately presented in more positive terms by others as a “refuge,” a “sanctuary,” and “home,” while others used adjectives like “tranquil,” “welcoming,” and peaceful.” A couple of participants also used “international” to describe the city. 2. What place do you like most about Diamond Bar, and why? Almost a third of participants mentioned something related to parks as what they liked most in Diamond Bar. Sycamore Canyon Park was the most commonly mentioned park, followed by Pantera Park. Trails and hiking/walking paths were also popular responses. The Diamond Bar Center another favorite aspect of Diamond Bar, with several participants pointing out its great views. Another popular response was “my home.” 1.1 Packet Pg. 304 1.1 Diamond Bar General Plan Update 3. What is the one thing you would do to most improve Diamond Bar? A few themes emerged in responses to this question. The most common suggestion was improvements related to traffic, mentioned by almost a third of participants. Some traffic responses were specific ("fix the 57/60 freeway," "less traffic on Grand," "larger roads"), while most simply cited traffic as the issue to fix. Over 20 percent of responses involved shopping, with several participants mentioning the Kmart site, others wanting more restaurants, and others desiring a new town center or entertainment center. Other common responses included placing limits on housing growth, prioritizing more parks and open space preservation, and improving the appearances of homes and yards. FUTURE GROWTH AND DEVELOPMENT Three questions were posed to address future growth and development in Diamond Bar. 4. What types of housing would you like to see in Diamond Bar and where should future housing be built? Over half of the 59 responses to this question indicated that participants did not want any more housing in Diamond Bar, with several responses stating that housing would bring more traffic. A quarter of responses expressed that they preferred single-family, low density housing. Another theme that emerged called for more senior housing (12 percent) in Diamond Bar. Only six participants communicated any desire for new apartments or condominiums, and of those participants, most responses stipulated low density and/or height. Four participants expressed that affordability was an important aspect of new housing development in Diamond Bar. S. What types of future employment and commercial uses are needed, and where should they be located? There was a strong consensus (71 percent) that respondents want to see more commercial uses in Diamond Bar. Over half of responses specified that they desired more retail uses, 37 percent of respondents voiced that they wanted more restaurants, and 14 percent expressed the need for more entertainment uses such as a movie theater in Diamond Bar. The two most common locations where participants wanted to see more commercial uses were at the intersection of Grand Avenue and Diamond Bar Boulevard, and the intersection of Golden Springs Drive and Diamond Bar Boulevard. Only six respondents communicated the desire for more office uses, and only four respondents voiced that they wanted to see more medical/ health related jobs in Diamond Bar. Packet Pg. 305 1.1 Report on Community Workshop #I 6. Do you think Diamond Bar needs a "downtown" or a "town center"? If so, where should it be, and what should be there? The majority of respondents (70 percent) communicated that they would like to see a downtown or town center in Diamond Bar, while 21 percent of respondents did not want one. Similar to the responses for the previous question, the two most common locations where participants wanted to see more commercial uses were at the intersection of Grand Avenue and Diamond Bar Boulevard (15 respondents), and the intersection of Golden Springs Drive and Diamond Bar Boulevard (20 respondents). Respondents also noted examples of downtowns or town centers that they liked and would want Diamond Bar's downtown to look like. The most common example was the Shoppes at Chino Hills (12 respondents), followed by Downtown Brea (six respondents). TRANSPORTATION AND CIRCULATION One question was posed to address traffic congestion and ways people get around the community. 7. How would you improve transportation? What would make it easier for you and your family to get around Diamond Bar? Responses to this question varied, but can be categorized in three ways: public transportation, traffic congestion, and bike and pedestrian improvements. The most popular response (50 percent) called for increasing/expanding public transportation throughout Diamond Bar. Participants specifically voiced that they wanted increased local bus service, as well as local shuttles that would serve seniors and disabled people. Other mobility responses were related to congestion (27 percent) and bike and pedestrian improvements (27 percent). Participants expressed the need for traffic improvements throughout Diamond Bar, such as improved traffic control systems and synchronizing lights. They also communicated the need for more bike lanes and paths, as well as wider and improved sidewalks. Four participants expressed that they didn't want any additional development in Diamond Bar in order to stop congestion from getting worse. Packet Pg. 306 1.1 Diamond Bar General Plan Update PARKS/OPEN SPACE One question was posed regarding the availability and adequacy of parks and open space in Diamond Bar. 8. What should the City do to improve recreation and open space opportunities (more parks, smaller or larger parks, more trails, athletic fields, etc.)? Responses to this question varied. Out of the 93 responses, 22 percent indicated that participants wanted more sports fields and facilities in Diamond Bar. Some specific facilities mentioned included a swimming pool, soccer fields, and tennis courts. Other popular community facilities that participants wanted to see were a teen center (14 percent) and a senior center (10 percent). The second most common response from participants indicated that they wanted more trails for biking and pedestrian uses (19 percent). Other popular responses included the desire to protect open spaces in Diamond Bar, as well as to provide more parks, each accounting for 13 percent of responses. OTHER PRIORITIES 9. What are other important priorities or issues that the General Plan could address? Responses to this question varied significantly. The most common responses were related to open space and land conservation (17 percent). Participants indicated that protecting existing open space, such as Tres Hermanos in Diamond Bar, was a priority. Another common set of responses touched on city beautification and home upkeep (16 percent). Other responses were related to mobility and traffic issues throughout Diamond Bar (11 percent). Participants felt that traffic and congestion were problems "near schools," "around Brea Canyon and Golden Springs," and "near the 57 and 60 freeways." Some participants also voiced concerns related to safety, including suggestions for neighborhood watch programs and security cameras, as well as for Diamond Bar to have its own police force. Multiple participants also pointed to a need to unify north and south Diamond Bar. 2.2 Activity #2: 2040 Vision for Diamond Bar After placing their post -it notes on the boards for the first activity, workshop participants moved back to small group tables. At the tables, participants were given blank magazine covers for a hypothetical special issue in the year 2040, celebrating Diamond Bar. They were asked to provide headlines or illustrations that captured their vision for Diamond Bar in 25 years. Each participant then shared their headline within their small group, and together each table came up with a group headline, either by selecting a favorite or creating a new headline combining components of individual headlines. Groups also discussed the common themes and ideas that emerged from the headline exercise. Group headlines and individual magazine headlines are summarized below. A larger selection of the magazine covers is provided in Appendix D.

SPECIAL EDITION DIAMOND BAR 2.3 Small Group Discussions Facilitators at each table asked participants to share their sense of the most important issues for the General Plan to address, drawing on ideas they considered in the magazine cover activity. Discussions at each table worked to identify the key issues or challenges on which most of the participants seemed to agree. One person from each table then shared these with the workshop audience. A facilitator recorded the priorities from the small group discussions. They are included as Appendix E, and summarized below, by theme, roughly in order of how many tables clearly identified related issues. CITY CHARACTER City character was a high priority for all groups and was the most popular topic of discussion. Themes and headlines about city character varied. A common theme that emerged at the table discussions was the "quiet" and "country living" in Diamond Bar. Participants used words and phrases like "serenity", "relaxed, rural living", and "small town" to describe their ideal Diamond Bar. Some table discussions focused on Diamond Bar's visual appearance. They used words and phrases like "beautiful neighborhoods," "clean city," and "keep it nice" to describe Diamond Bar's character. Participants also mentioned other positive attributes like "model for cultural diversity" and "friendliest city." PARKS, RECREATION, AND OPEN SPACE Another popular topic that was discussed by most groups was the parks, recreation, and open space resources in Diamond Bar. Participants indicated that open space and wildlife conservation were important to the character of Diamond Bar. They used words and phrases like "healthy wildlife," "wildlife corridor survives!" and "best city for open space and wildlife conservation." Some groups Packet Pg. 309 Report on Community Workshop #I stressed the importance of preserving open space and the natural views, as well as making new development low impact. SAFETY A few groups discussed issues of safety in Diamond Bar. Headlines such as "Diamond Bar wins the safest city" and "safest city" indicate that participants see safety as a priority for Diamond Bar's future. A few participants also voiced that they desired additional enforcement to maintain the safety of Diamond Bar. They wanted "stricter enforcement to maintain neighborhoods" and to "maintain tranquility" throughout Diamond Bar. COMMUNITY FACILITIES I e ld., Another key issue that several groups discussed was community facilities in Diamond Bar. Participants indicated that they wanted to see more facilities for the youth, such as soccer fields, baseball fields, and basketball courts. Two groups also discussed adding resources and infrastructure for the senior population of Diamond Bar. HOUSING A few groups discussed housing and homeownership issues in Diamond Bar. One group wanted to promote home upkeep and "improve homeowner pride." Another group discussed a desire for the development of new single family homes consistent with the existing homes in Diamond Bar. One group did not want any new housing in Diamond Bar. 9 1.1 Packet Pg. 310 Diamond Bar General Plan Update tiIivl-t f_V :I_171, h iv1 Sustainability was a topic of discussion for a few groups. Participants indicated that they wanted Diamond Bar to be a "green city" and implement sustainable practices. They used words and phrases such as "smart, green city", "environmentally friendly", and "sustainable projects." SCHOOLS Three groups discussed Diamond Bar's schools, where two themes emerged. One theme celebrated the success of Diamond Bar's schools. Two magazine headlines stated "best schools in the state" and "Diamond Bar celebrates 20 years as a model for student learning." Another group noted that it was important for Diamond bar to have one unified school district. MOBILITY AND TRANSPORTATION Several groups discussed issues of mobility in Diamond. Four groups wanted to see Diamond Bar become pedestrian friendly, while another four groups discussed reducing traffic congestion. One group's headline suggested rerouting the 57 and 60 freeways to be underground. 2.4 Summary Several common and often interrelated themes emerged from the workshop's activities. While traffic was a concern in itself, it also influenced many participants to oppose new development, especially residential development. Concern about development also tied in with community desires to preserve open space resources, as well as appreciation for the peaceful, safe aspects of Diamond Bar that the community has been known for. Despite the concerns about development and traffic, over 70 percent felt that the city should have more commercial uses and that it needs a town center. Many participants also spoke of a need, largely because of the multiple school districts, to unify the north and south ends of the city. Another strong theme of the workshop was aesthetics. Many participants expressed a desire to improve home upkeep, as well as a wish to improve the condition of the city's shopping centers and beautify the city as a whole. The needs of both the oldest and youngest residents were also very prevalent throughout the course of the evening's activities. Priorities regarding the aging population that repeatedly arose in discussions included needs for senior housing, a senior center, and better public transportation and walkability. In addition to improved mobility, priorities related to youth included sports fields and facilities, a teen center, school quality, and unification of the school districts. 2.5 Next Steps To build on the feedback gathered from the first workshop, the online survey will continue to be promoted through the website as well as at various events in the city. At the same time, background research on topics including land use, development potential, transportation, public facilities/services, and environmental factors is underway. Land use and development alternatives will then be drafted that are based on the combined findings of the technical research and the input on key issues and opportunities from community members. 10 1.1 Packet Pg. 311 Report on Community Workshop #I Appendix A: Workshop Agenda 1.1 Packet Pg. 312 1.1 ►'�:� DIAMOND BAR GENERAL PLAN UPDATE AGENDA Diamond Bar General Plan Update Community Visioning Workshop #I 1.

The General Plan Update provides an exciting opportunity for community members to envision the city's future and identify long-term goals and direction for development. The updated General Plan will articulate a long-term vision for Diamond Bar and outline policies and programs to realize this vision. For more information on the General Plan Update process, please visit: www.diamondbargp.com. The creation of an online survey, focused on exploring community members' visions for the future of Diamond Bar and major issues related to various aspects of life in Diamond Bar, constituted a key element of the public outreach for the General Plan Update. This survey was developed using Typeform, an online survey tool, and made available at www.DiamondBarSurvey.com in October 2016, in English, Korean, and Chinese. The survey was promoted through various sources: on the website for the General Plan Update, through an email list of those who subscribed for updates on the General Plan Update, through a newsletter mailing, a Facebook campaign, and through flyers distributed at "pop-up" booths set up at four different events (Barktober Fest, the Quail Summit Elementary School Carnival, the Eco Expo, and the Diamond Bar High School Food Festival). In addition to promoting the survey with flyers, representatives at the pop-up booths were available to administer the survey using iPads. The survey received 501 responses, including 488 responses in English and 13 in Chinese. The online survey is a core piece of the initial phase of outreach for the General Plan Update, which consisted of various activities to ensure that the General Plan Update reflects the community's most important values and priorities. In addition to the online survey, the General Plan Update website, and the previously mentioned pop-up booths, the initial phase of outreach included stakeholder interviews and a community workshop. This report summarizes the feedback provided by the online survey. In addition, the opening activity in the first community workshop included several questions that were intended to reflect those in the online survey. Where appropriate, input from the online survey has been compared alongside input from the first community workshop. The community workshop also contained additional activities that are not discussed here; a summary report of the first community workshop can be accessed at the General Plan Update website. Feedback from the online survey and the community workshop, in addition to the Existing Conditions Report, will serve as a valuable reference to guide City staff, the Planning Commission, the City Council, the consultant team, and others in formulating land use and transportation alternatives and the policy framework for the updated General Plan. Packet Pg. 370 1.1 Survey Report 2 Survey Results Highlights of both the online survey and the first community workshop (in instances where community workshop input overlapped with topics raised by the survey) are discussed and summarized below. The full set of responses to open-ended questions is included in Appendix A. 2.1 Analysis of Survey and Workshop Responses Participants of the online survey were asked 16 questions that explored current planning issues in Diamond Bar as well as what will be of future concern for the General Plan Update. Some questions were open-ended while others provided multiple choices, prompting respondents to select one or multiple answers. Many of the multiple choice questions also provided an "Other" option that allowed respondents to enter free -form answers. Open-ended responses were synthesized and summarized to reveal broader patterns of responses. The percentages below refer to the percent of respondents that either chose a response, in the case of multiple choice questions, or named the given subject in their response to an open-ended question or specification of an "Other" choice. In many cases, participants gave multiple responses or did not fully answer a question, thus totals may not add up, or may add to more than 100 percent. Many of the questions that were asked in the online survey were also asked at the first community workshop, though not always with the same exact phrasing or answer choices. The feedback for the online survey and community workshop are analyzed separately, both due to the differences in format as well as a precaution against double counting of responses, as some workshop participants also participated in the online survey. However, they are presented together in this report to show a more complete picture of outreach gathered for the project through multiple channels. By asking similar questions through different venues (an in-person workshop versus an online survey), we are able to ensure that we are hearing from a broad spectrum of the community and can better identify areas of consensus. IDENTITY AND VISION The survey began with two questions that addressed the identity of Diamond Bar. I. What word do you think best defines Diamond Bar? Online Survey The most common word was "safe," mentioned by over eight percent of the 501 respondents (40 total). "Community", "family," "peaceful," and "quiet," were the next most popular answers, each accounting for five to six percent of responses. While the top responses were all quite positive, "traffic," "congested," and "crowded" collectively accounted for over four percent of responses. A similar percentage used the words "suburb" and "bedroom community." Thirteen respondents (nearly 3 percent) described Diamond Bar as "boring." Other often -cited words included "clean," "home," "beautiful," and "schools."

Diamond Bar's traffic issues were the only source of negative word connotations, which included "congested," "over crowded," and "gridlock." Multiple participants described the city as a "bedroom community," which was alternately presented in more positive terms by others as a "refuge," a "sanctuary," and "home," while others used adjectives like "tranquil," "welcoming," and peaceful." A couple of participants also used "international" to describe the city. 2. What place do you like most about Diamond Bar, and why? Online Survey Over 40 percent of respondents mentioned some form of green space as their favorite place, including parks, trails, open space, or views. Breaking this down further, 32 percent of respondents overall mentioned parks, 15 percent mentioned trails, and seven percent mentioned open space or views. Sycamore Canyon was highlighted by 10 percent of respondents, with many respondents also mentioning Pantera Park or the dog park. Nine percent of respondents said their favorite place was their own home, while three percent mentioned their neighborhood or a neighborhood. Other popular responses included schools (seven percent), the Diamond Bar Center (six percent), and City Hall/library (five percent). 3 Packet Pg. 372 Survey Report Figure 2-2: Question 2 - "What place do you like most about Diamond Bar, and why?" alm— lose— IM Community Workshop Halla OMM"n: 1.1 Diamond Bar General Plan Update Figure 2-3: Question 3 - "What types of housing would you like to see in Diamond Bar?" 60% 56% 50% 40% 32% 30% 20% 10% 0% Diamond Bar Single family doesn't need any detached homes more housing Community Workshop 12% II% 7% 3% Senior housing Townhouses and Apartments Other condominiums Over half of the responses to this question indicated that participants did not want any more housing in Diamond Bar, with several responses stating that housing would bring more traffic. A quarter of responses expressed that they preferred single-family, low density housing. Another theme that emerged called for more senior housing (12 percent) in Diamond Bar. Only six participants communicated any desire for new apartments or condominiums, and of those participants, most responses stipulated low density and/or height. Four participants expressed that affordability was an important aspect of new housing development in Diamond Bar. 4. Where should future housing be built? Online Survey Thirty four percent of respondents wanted to see future housing built in future growth areas outside the Diamond Bar city limits, followed by 31 percent wanting to see housing built as part of future redevelopment of other parts of town (e.g., older or vacant shopping centers), and 29 percent wanting to see housing in the Tres Hermanos area. Only 11 percent of respondents wanted to see housing on the current golf course site (though as seen later in the survey, respondents were not very protective of the golf course in general). Another 11 percent of respondents chose "Other", and all but a handful of those respondents indicated that there should be no more housing. Given the majority of respondents indicated Diamond Bar doesn't need more housing in the previous question, it is likely that such an answer would have been the most popular choice if offered for this question as well. As with many other questions in the survey, participants could pick multiple responses, so totals add to more than 100 percent.

A few mentioned wanting to limit housing to only along freeways, near the Metrolink rail line, and/or near shopping centers. A couple others said they only wanted to see housing if it replaces existing dilapidated housing, not on undeveloped land. S. What types of new employment and commercial uses are needed in Diamond Bar? Online Survey Survey respondents were much more amenable to additional employment and commercial uses than housing. Approximately two-thirds of respondents wanted more restaurants, 58 percent wanted more entertainment uses, and 45 percent wanted more family events and activities. Respondents were less concerned about whether the businesses were local versus regional or national businesses, though respondents had a slight preference for small, local businesses. Relatively few respondents (eight percent) wanted to see more offices. Of the four percent of respondents who chose "Other," the most common response was for grocery stores, with four respondents specifically mentioning Trader Joe's. As with many other questions in the survey, participants could pick multiple responses, so totals add to more than 100 percent. 6 1.1 Packet Pg. 375 1.1 Diamond Bar General Plan Update Figure 2-5: Question 5 - "What types of new employment and commercial uses are needed in Diamond Bar?" 70% 67% 58Jj C) /O 60% 50% 45% 40% 36% 33% 30% 20% 10% 0% Restaurants Entertainment Family events Small local Large regional and activities businesses or national chain stores Community Workshop 8% 5% li M Offices Other There was a strong consensus (71 percent) amongst respondents that they wanted to see more commercial uses in Diamond Bar. Over half of responses specified that they desired more retail uses, 37 percent of respondents voiced that they wanted more restaurants, and 14 percent expressed the need for more entertainment uses such as a movie theater in Diamond Bar. 6. Where should future employment and commercial uses be located? Online Survey There was little consensus on where future employment and commercial uses should be located, with each multiple choice answer receiving between 23 and 37 percent of responses. The most popular answers were to locate these uses near freeway exits (37 percent), near the Metrolink station (32 percent), and at major intersections (31 percent). While the most popular location for future housing was outside the city limits, the same location ranked only fourth out of six options employment and commercial uses, reflecting respondents' strong preference for employment and commercial uses over residential uses within the city. The most popular "Other" response was the Kmart site, mentioned in 14 responses (3 percent). As with many other questions in the survey, participants could pick multiple responses, so totals add to more than 100 percent. 7 Packet Pg. 376 Survey Report Figure 2-6: Question 6 - "Where should future employment and commercial uses be located?" 50% 40% 37% 32% 31% 30% 26% 24% 23% 20% 10% 0% Near freeway Near the At major Future growth Golf course Vacant land exits Metrolink intersections areas outside (replacement between Station (e.g., Diamond the current of the existing Diamond Bar Bar Blvd and city limits land use) and Chino Grand Ave, Hills (Tres etc.) Hermanos land) Community Workshop 6% M Other The two most common locations where participants wanted to see more commercial uses were at the intersection of Grand Avenue and Diamond Bar Boulevard, and the intersection of Golden Springs Drive and Diamond Bar Boulevard. Only six respondents communicated the desire for more office uses, and only four respondents voiced that they wanted to see more medical/health related jobs in Diamond Bar. 7. Do you think Diamond Bar needs a "downtown" or a "town center"? Online Survey The majority of respondents (69 percent) communicated that they would like to see a downtown or town center in Diamond Bar, while 27 percent of respondents did not want one. Three percent of respondents indicated in their "Other" response that they were not sure, with several respondents indicating that a town center would be nice, but not if it would increase traffic. 8 1.1 Packet Pg. 377 1.1 Diamond Bar General Plan Update Figure 2-7: Question 7 - "Do you think Diamond Bar needs a `downtown' or a `town center'?" Maybe/l 3% Yes 69% Community Workshop The majority of respondents (70 percent) communicated that they would like to see a downtown or town center in Diamond Bar, while 21 percent of respondents did not want one. 8. What should be located at the town center? Online Survey Of those respondents that said they would like Diamond Bar to have a town center, the only choice given for uses at the town center receiving a majority of support was restaurants (61 percent). There was also strong support for a movie theater or playhouse (46 percent); activities, events, and programming for families and nearby residents (43 percent); arts and cultural activities (42 percent); and small specialty stores (41 percent). Some respondents used the "Other" category to describe town centers outside of Diamond Bar that they wanted to emulate, such as Pasadena, San Juan Capistrano, and Chino Hills. As with many other questions in the survey, participants could pick multiple responses, so totals add to more than 100 percent. 9 Packet Pg. 378 1.1 Survey Report Figure 2-8: Question 8 - "What should be located at the town center?" 0% 10% 20% 30% 40% 50% 60% 70% Restaurants A movie theater or playhouse 46% Activities, events, and programming for families and nearby 43% residents Arts and cultural activities 42% Small specialty stores 41% A public plaza or park 35% Bars, nightlife, and evening entertainment 33% Large stores 24% Mixed-use development (housing above retail) - 18% Offices 8% Hotel 7% Housing = 4% Other 1 2% 61% Community Workshop Workshop participants noted several examples of downtowns or town centers that they liked and would want Diamond Bar's downtown to look like. The most common example was the Shoppes at Chino Hills (12 respondents), followed by Downtown Brea (six respondents). 9. If you think Diamond Bar needs a "downtown" or a "town center," where should it be? Online Survey Of those respondents that said they would like Diamond Bar to have a town center, the most popular location given was Diamond Bar Boulevard near SR 57 and SR 60 (27 percent), followed by the intersection of Grand Avenue and Diamond Bar Boulevard (23 percent), and the current site of the golf course (21 percent). While the choices offered were more specific than those offered for the question of where to locate future employment and commercial uses, it is notable that the Metrolink station area, which was the second most popular choice of where to locate future employment and commercial uses, was the least popular choice of where to locate a town center. This choice ranked even below the Tres Hermanos area, which many respondents commented that they wanted to see protected. Most of the "Other" responses mentioned either the Kmart site specifically or the north end of Diamond Bar, both locations that align most closely with the answer Packet Pg. 379 1.1 Diamond Bar General Plan Update choice of Diamond Bar Boulevard near SR 57 and SR 60, which would further inflate that answer's lead if recategorized.

TRANSPORTATION AND CIRCULATION One question was posed to address traffic congestion and ways people get around the community. 10. Thinking about how you get to work, school, and other activities, pick the top three possible transportation improvements you'd like to see. Online Survey Two thirds of survey respondents picked congestion on city streets as one of their top three priorities for transportation improvements, followed by freeway congestion (62 percent), safety/ease of walking (38 percent), and convenience of public transit (33 percent). Only 28 percent of respondents chose safety/ease of bicycling as one of their top three improvements. As with many other questions in the survey, participants could pick multiple responses, so totals add to more than 100 percent.

The most popular response (50 percent) called for increasing/expanding public transportation throughout Diamond Bar. Participants specifically voiced that they wanted increased local bus service, as well as local shuttles that would serve seniors and disabled people. Other mobility responses were related to congestion (27 percent) and bike and pedestrian improvements (27 percent). Participants expressed the need for traffic improvements throughout Diamond Bar, such as improved traffic control systems and synchronizing lights. They also communicated the need for more bike lanes and paths, as well as wider and improved sidewalks. Four participants expressed that they didn't want any additional development in Diamond Bar in order to stop congestion from getting worse. 12 1.1 Packet Pg. 381 1.1 Diamond Bar General Plan Update PARKS/OPEN SPACE One question was posed regarding the availability and adequacy of parks and open space in Diamond Bar. 11. Pick your top three improvements for parks, open space, and recreation opportunities. Online Survey When asked to choose three improvements for parks, open space, and recreation opportunities, there was very little separation between the four most popular choices, each of which was chosen by 44 to 46 percent of respondents: 1) trails, 2) a new grand park, 3) picnic areas and playgrounds, and 4) outdoor athletic facilities. Indoor athletic facilities (27 percent) and hard courts (20 percent) received significantly less support, which may be explained by a narrower group of potential users for these facilities. As with many other questions in the survey, participants could pick multiple responses, so totals add to more than 100 percent.

Twenty-two percent of participants indicated they wanted more sports fields and facilities in Diamond Bar. Some specific facilities mentioned included a swimming pool, soccer fields, and tennis courts. Other popular community facilities that participants wanted to see were a teen center (14 percent) and a senior center (10 percent). The second most common response from participants indicated that they wanted more trails for biking and pedestrian uses (19 percent). Other popular responses included the desire to protect 13 Packet Pg. 382 1.1 Survey Report open spaces in Diamond Bar, as well as to provide more parks, each accounting for 13 percent of responses. 12. Which statement best reflects your feelings about the golf course? Online Survey The golf course did not seem to elicit strong sympathy, or strong interest of any kind, among survey respondents. The most common statement chosen (by a small margin) was that the golf course should be removed/relocated for a different use (29 percent), while 27 percent of respondents had no opinion on the golf course. The choices to have the golf course be renovated/update or remain unchanged were each chosen by 22 percent of respondents. Figure 2-12: Question 12 - "Which statement best reflects your feelings about the golf course?" 50% 40% 29% 30% 20% 10% 0% The golf course should be removed/relocated to make way for a different use of the site. 27% 1 have no opinion on the golf course. 22% The golf course should be upgraded/renovated. 22% The golf course should remain as it is. 13. Which statement best reflects your feelings about the vacant land between Diamond Bar and Chino Hills (Tres Hermanos land)? Online Survey The Tres Hermanos area seemed to be of more interest to survey respondents than the golf course. Over half (56 percent) indicated that the Tres Hermanos area should remain as it is, while 31 percent felt it should be developed to serve the city's needs. Only 13 percent of respondents were unsure or had no opinion. 14 Packet Pg. 383 1.1 Diamond Bar General Plan Update Figure 2-13: Question 13 - "Which statement best reflects your feelings about the vacant land between Diamond Bar and Chino Hills (Tres Hermanos land)" 60% 56% 50% 40% 30% 20% 10% 0% 31% The land should remain as it The land should be is developed to serve the city's needs OTHER PRIORITIES 13% ke Unsure/ no opinion 14. What are other important priorities or issues that the General Plan could address over its 20 -year timeframe? Online Survey Survey respondents brought up a variety of issues, many of which were explored in other parts of the survey. Over a quarter of the responses mentioned traffic congestion and management issues. Some responses were fairly general in asking for traffic to be improved, complaining that local streets are being used as freeway bypasses by people living outside of Diamond Bar. Diamond Bar Boulevard received the most complaints about congestion. A few specific traffic interventions were mentioned, such as better traffic signal synchronization, and creating a parallel road to Diamond Bar Boulevard. Many of the responses about traffic also called for limits on growth and density, which was often seen as the cause of the city's congestion problems. About 20 percent discussed the retail environment, with the most attention given to dining and entertainment. Many respondents wanted to see a wider range of cultural options in the retail environment, particularly for restaurants, to reflect the community's diversity. Others wanted specifically to see more national retailers and chain stores, with many specifically citing grocery stores like Trader Joe's, Whole Foods, or Sprouts. Several respondents wanted to see the City do more to address the blight caused by vacant stores and outdated shopping centers. Parks, trails, and open spaces were the subject of about 17 percent of responses, with respondents generally wanting more parks and the preservation of open spaces, primarily the Tres Hermanos area. Specific improvements suggested included lighting in Sycamore Park, as well as a walking trail at the west end of Morning Canyon Road. 15 Packet Pg. 384 Survey Report Issues of beautification were present in another ten percent of responses, which included mentions of home upkeep, cleanliness of shopping centers, and maintenance. Various aspects of safetywere discussed, ranging from desires for Diamond Bar's own police station to growing dangers from coyotes. Other improvement suggestions brought up by multiple respondents included better street treatments, such as adding LED street lights and planting more trees. While many respondents wanted trees planted in public rights of way, a few others complained of overgrown trees in neighboring properties that were blocking views. Other specific improvements suggested included a public pool, and a movie theater. Other themes appearing in multiple responses included the divide between north and south, environmental sustainability, making the city friendlier to families and seniors, public transportation and walkability, and the retention of businesses and jobs.

The most common responses were related to open space and land conservation (17 percent). Participants indicated that protecting existing open space, such as Tres Hermanos in Diamond Bar, was a priority. Another common set of responses touched on city beautification and home upkeep (16 percent). Other responses were related to mobility and traffic issues throughout Diamond Bar (11 percent). Participants felt that traffic and congestion were problems "near schools," "around Brea Canyon and Golden Springs," and "near the 57 and 60 freeways." Some participants also voiced concerns related to safety, including suggestions for neighborhood watch programs and security cameras, as well as for Diamond Bar to have its own police force. Multiple participants also pointed to a need to unify north and south Diamond Bar. 16 1.1 Packet Pg. 385 1.1 Diamond Bar General Plan Update IS. If you would like to provide any more detail or clarification on any question or topic, please do so here. Online Survey Survey respondents used this space primarily to reiterate and summarize feedback given in other parts of the survey, as well as give more detail on specific recommendations. Specific recommendations for this question included soundproofing freeway overpasses, support of neighborhood watches, toll fees for nonresident traffic, and repeated calls for a movie theater and premium grocery stores. Others suggested that the best cities around the country should be referenced as examples. A few of the responses reflected on the "country living" ethos. One said, "I moved to Diamond Bar because of the open space. I pray we will not lose the country feel." Another said, "I have lived in Diamond Bar 44 years, it would be great if the original `country living' was true, but since progress has moved it beyond that, make it a place we want to shop, eat, play, enjoy." Another respondent was seemingly concerned about the demographics of participants of General Plan Update process, saying "I was at the community workshop and was disturbed but not surprised to see that the median age was about 55." 16. Thinking into the future, what is the one thing you would do to most improve Diamond Bar over the next 20 years? Online Survey Similar to Question 15, most responses reiterated feedback given elsewhere in the survey. Responses related to traffic were most common. While the majority of these answers were very general, several respondents specifically cited the 57/60 interchange as the area needing the most improvement, even though elsewhere in the survey, traffic along Diamond Bar Boulevard received the most attention. A need for adequate parking was also mentioned. Many respondents mentioned the need for more retail, dining, and entertainment options. The phrase "more entertainment" was repeated often. One respondent wrote, "If there is no entertainment for young adults, this city will be nothing but children and old people." Several respondents framed their responses around the city's economy, saying the city needed to grow its tax base by providing more options for shoppers, so that shopping dollars do not all migrate out to neighboring cities like Brea and Chino Hills. Responses related to parks, trails, and open space were very common, as elsewhere in the survey. Allusions to some form of a town center were more common here than in other open-ended responses. Respondents also repeatedly brought up the need to beautify the city, keep it safe, and make it friendly for families and their children. Community Workshop The most common suggested improvements related to traffic, mentioned by almost a third of participants. Some traffic responses were specific ("fix the 57/60 freeway," "less traffic on Grand," "larger roads"), while most simply cited traffic as the issue to fix. Over 20 percent of responses 17 Packet Pg. 386 Survey Report involved shopping, with several participants mentioning the Kmart site, others wanting more restaurants, and others desiring a new town center or entertainment center. Other common responses included placing limits on housing growth, prioritizing more parks and open space preservation, and improving the appearances of homes and yards. 2.2 Next Steps Together with existing conditions research and input from other community outreach activities, the survey results will be used to inform development of various land use development scenarios. These scenarios will represent ways in which Diamond Bar could grow and change over horizon of the General Plan. The scenarios will be evaluated for their impacts on transportation, infrastructure, environmental factors, fiscal conditions, and housing/jobs balance. Results of this evaluation will be shared with the public, and Diamond Bar community members will have the opportunity to share which scenario would be the best choice for Diamond Bar in the future. Ultimately, the Planning Commission and City Council will provide direction on a Preferred Land Use Plan, on which policies for the updated General Plan will be based. Following the establishment of the Preferred Plan and its approval by the City Council, the General Plan document itself will be crafted. There will be numerous opportunities for the public to review and comment on the draft Plan throughout the remainder of the General Plan update process. 18 1.1 Packet Pg. 387 Diamond Bar General Plan Update Appendix A: Open -Ended Responses I.

(28 Responses Total) 1. A gathering place perhaps where K -mart is. But no housing 2. A town center only makes sense in an already developed area. NO NEW DEVELOPMENT!! Brea did an excellent job of turning an impoverish commercial area into a thriving town center. We could learn from their example. 3. DB has never had a town center. We need an area (s) were ppl can congregate as a community. It would have been nice to have an explanation here as to what your definition of each idea 39 Packet Pg. 408 1.1 Survey Report 4. 5. 6. 7. 8. 9. 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 DeMaybe, pending on what's in the so-called "town center" and how it would affect our local traffic. Diamond Bar should have more of a town center at Grand and DB Blvd. Entertainment Center I think it is too late. Too much traffic around Diamond Bar Blvd., which would have been the most logical spot I would consider Grand and DB Blvd to already be it. I'm not sure what that would look like or where something like that would go??? What is being done about the ugly tumbleweed farm you made next to people's homes off of grand? if designed and located properly it could work well It would be nice for a sense of community, but not at the risk of cauing more congestion and traffic. It would be nice to have a town center but it seams to be not possible May be a nice idea if it does not negatively impact existing residential areas more traffic Need to redevelop the corner of Diamond Bar Blvd. & Grand Ave. Too difficult to park and drive here. Too much congestion, I avoid it. Not necessary in one location due to traffics congestion. Sh There are enough established commercial areas without having just one main center. Use the land and buildings that are here and make them useful to all. Tres Hermanos Land Unsure (5) Use the Diamond Bar Center to develop a downtown area we have places that could count We have three major areas already Whichever that won't make our streets busy. Yes, but depends upon how it's created and where. 8. What should be located at the town center? Q Responses Total) 1 2. 3. 4. 5. 6. 7. 40 Emphasis on a variety of things, and not the same types of businesses. My family and I currently go to Chino Hills or elsewhere for restaurants because DB is limited in that aspect. We have several Asian restaurants, but limited American theme restaurants. Markets, coffeehouse Outdoor courtyard with music Retail clothing, food, art Similar to old town Pasadena or San Juan Copistrano Unsure Where is this? Packet Pg. 409 1.1 Diamond Bar General Plan Update 9. If you think Diamond Bar needs a "downtown" or a "town center," where should it be? (27 Responses Total) 1. a, c, d 2. Close to city of Industry 3. grand near freeway or something at old Kmart location 4. in most of these areas traffic already is an issue. Need for improvement on that end before any development can take place. 5. it's already at Grand & DB Blvd, just needs less Asian restaurants/business and more inclusive/diverse choices. 6. Kmart (7) 7. Leave tres hermanos alone! ! ! 8. Location by the main intersection or transportation hub would be ideal. But how to deal with traffic congestion? Bus or light rail from parking structure to the town center? 9. Near the country - near super H 10. No clue 11. North Diamond Bar 12. North end. The area needs some attention. 13. Old Kmart center 14. Old Kmart center maybe 15. Old vacant shopping area 16. The KMART lot 17. The new design of the village area at Golden Springs and Diamond bar Blvd. 18. Use current land where stores already are there 19. vacant Kmart 20. Where Kmart used to be 21. Where Kmart used to be or intersection of Grand and Diamond Bar Blvd 14. What are other important priorities or issues that the General Plan could address over its 20 -year timeframe? (347 Responses Total) 1. --Affordable after school activities for middle school and high schoolers. --Make it a priority to bring new businesses and don't keep lots vacant (Ralph's & K -mart) for years. --In my experience affluent neighborhoods distinguish themselves from others by their tree lined streets, parks and fields. --Keep Diamond Bar green areas, bring relevant businesses to the various shopping centers and stop over development! 2. (1) Reduce freeway traffic congestion from flowing over to city surface streets. 3. 1:No more homes built, it is already overcrowded. 2:Get a couple of good grocery stores at south end 3: there is not much to keep people buying here in diamond bar 4: look at Brea and Chino Hills, both have great shopping and entertainment areas 4. 1. Keeping residential population at current levels 41 Packet Pg. 410 Survey Report 5. 1. Please plant more trees on main road like road sides and islands on Diamond Bar Blvd. 2. Need more variety of restaurants, also need a big shopping mall like The shops in Chino Hills or Spectrum in Irvine. 3. Can we have Whole Foods Market or Trader Joe's? 4. Can we have a gym managed by city government? Which only serve Diamond Bar residents(need to show ID to prove they live in Diamond Bar, no need the membership.). And for the fee, for example, pay $5 for each hour. 6. 1. Protect the space between Diamond Bar and Chino Hills from any human activities and save it for non -human residents (wild life). Let it develop its own eco -system (food chain among wild life) to decrease wild life attacks on residential pets and small children. 2. Create and support citywide clean/renewable energy in governmental, commercial and residential areas. City should take initiative in using/developing renewable energy and set the example. 3. Create inclusive community atmosphere by planing fun cross-cultural/ethnic community activities (involving food, music, entertainment and information) as a way to recognize and embrace our diverse population within our city. 7. 1. Safety 2. Enrichment in schools 3. Fiscal responsibility 8. 57 traffic 9. A little more business in the city. 10. Activity s and crowded area 11. Add beauty elements and community activity options to North Diamond. 12. Add more entertainment to help Diamond Bar thrive as well as fixing traffic congestion. Ensure that grass stays healthy and flowers bloom. Keep the Tres Hermanos land as it is. 13. Add more restaurants 14. Add more updated shopping centers like those seen in the city of chino hills. Update our parks especially for kids. 15. Add speed bumps/humps or other traffic calming tactics near Pantera park. 16. Affordable assisted living, senior services for transportation and support, adult day care, a true downtown area for civic events, food entertainment, shopping and pedestrian safety 17. Affordable homes 18. Affordable housing 19. Affordable housing walkability; public transportation 20. affordable town house/condominiums 21. aging in place, environmental sustainability, walkable city, identity and branding, community gathering places 22. Although we have a large number of Asian residents, we need to stop filling every retail space with Asian restaurants. Our city has more than enough of these, and we need to be careful not to become the next Rowland Heights. My family is Asian, but I never want to drive down the streets of Diamond Bar and have every sign be in Chinese or Korean. I want a town full of diversity -- diversity in its residents, culture, and food. And this of course should include American fare. I constantly hear residents complain about the lack of breakfast places. We once had Dennys, Bobs Big Boy, Cocos, and Carrows. Now every one of those is gone. 23. Arts and Culture 24. As I said we need to have more open spaces. Wild life corridor, more parks like Pantera that people can use to wind down and recharge. Not seeing that traffic is going to lessen on the 42 1.1 Packet Pg. 411 1.1 Diamond Bar General Plan Update freeways. The "fix" won't happen for another 30 years and then it will be out of date. so we need to do something to help people regenerate and enjoy. Nature's the way. 25. Athletic fields 26. Beautification and update older tracks in the west end of town. There is a small plot of land at the end of Flintgate Dr that is empty and void of any interest. It would be nice if it was a small park for sitting with drought tolerant landscaping and some shade. 27. Beautification including trees, new restaurants 28. Beautification of residential streets to improve property value. Enforcement of parking codes - Example: People are parking trucks larger then 10,000 lbs. 29. Better local public transportation system. Safer walking paths especially between diamond bar high and pathfinder and Brea canyon road and Golden Springs Rs. Traffic lights smarter. Movie theatre. Develop Kmart complex into state of the art restsurant and shopping complex with entertainment like chino hills Shoppes. Becoming more self contained so we don't have to go out of town for our residentialbrequirements. 30. Better oversight of property maintenance for residential properties that are visible from public streets. 31. Better plaza near KMart 32. better public transportation 33. better shopping places 34. Better use of office buildings on Pathfinder & Brea Rd, 35. Bordering on City of Industry is a challenge for Diamond Bar as City of Industry has completely different priorities. Mitigating any negative effects that City of Industry growth plan has on Diamond Bar. 36. Brea canyon road is used in place of the freeways for commuting. Waze and similar apps are directing traffic in residential neighborhoods (cold spring ambushers rd castle rock) 37. Bring new businesses in and the ability to keep them. We have to go to other cities for shopping /entertainment/hospitals. 38. Bringing in more variety in the restaurants and shops that open. 39. Build a shopping mall 40. Build hospitals/patient care facilities. Educate residents to follow traffic rules. Build more walking trails. 41. Build retail space to provide a better tax base to help fund all the future projects. Improve North DB to "match" SD. ND is becoming run down and we should unify the entire city instead if having it divided as it currently stands. 42. Can you build a 50 -meter indoor pool 43. Careful plan of what goes into old K -Mart - no in dog swap meet 44. Cheep or free transportation specifically for seniors (65 +) & those with temporary & fixed disabilities so they can get their groceries & do light shopping. SUV's that cruise the entire length of Diamond Bar Blvd. & Grand, & part of Golden Springs. 45. City needs to bring in at least one to two major Chinese Supermarkets for the heavily populated Chinese residents. Add thousands of units affordable senior housing near major shopping centers. Improve safety standard for the high crime areas within the city. Assist homeowners with landscaping for single family homes to improve the city images. Build or 43 Packet Pg. 412 Survey Report rebuild a big shopping center with multiple major anchors at the intersection of Grand Ave and Diamond Bar Blvd which is the heart of the city. Eliminate homeowner associations entirely around the city and put heavy emphasis on local parks with more upgrades. Change street lights with new LED lights to make streets brighter and safer to walk at night. And finally, follow any footprints that make sense coming from the City of Irvine. 46. City shuttle like Carpenteria, Ca 47. Clean up freeway entrances in to DB - they are trash dumps and reflect poorly and the great efforts to maintain city design and beauty. I would like to see more home owner ship pride. Many homes are in decay and not being maintained to support neighborhood property values. 48. Clean up major streets, Golden Springs and Diamond Bar Blvd. Looking at the backs of homes and how messy they are is such an eye sore. Compare them to Grand in Chino Hills and it's very disappointing. 49. Cleaner park bathrooms 50. Climate change 51. Closed businesses for a long period of time makes the city feel and look unsafe. Something needs to be done with theses abandoned lots and stores. 52. Commercial property and home safety 53. Congestion on Brea Cyn Cutoff and Diamond Bar Blvd 54. Could we please have actual sand or round gravel instead of wood chips? Little ones fall in them and they HURT. They get in my shoes and they HURT. And could you please install better quality and educational playground equipment's? My 2 year old fell through the chains of the bridge in Heritage Park and fractured her wrist. Existing parks are not up to code probably. Instead of developing new, you could just tweak and existing parks by continuous improving them. Probably costs less. 55. Create a Diamond Bar Police Department and improve on traffic issues throughout the city, mainly during rush hour and on the freeways. 56. create a fun downtown area like Chino Hills or Brea 57. Create more businesses so we don't have to drive to chino hills for EVERYTHING 58. Creating a High Speed Internet Utility. Holding onto and creating more 'green spaces' (parks, nature sanctuaries) 59. Creating a more diverse business, shopping, dining and overall experience within the city, not so dominated by Asian interests. Do not let Diamond Bar become another Little Saigon. 60. Crime rate and coyotes (safety measures). 61. Currently, my family and I are constantly in Chino Hills and/or Walnut for a variety of things such and shopping and eateries. We stay in DB when we can, but choices become limited very fast. A lot of things cater to the Asian communities which is fine, but Diamond Bar should not be in the future, what Rowland Heights is right now. We should continue to seek out businesses that will attract people from everywhere else, instead of sending the residents of DB to go elsewhere for business. The housing situation is fine. I don't feel that we need to build more housing since that has already been done near the Target as well as off the 57 and Brea Canyon Rd. I miss the days when we had a Sizzler, Bob's Big Boy, and 44 1.1 Packet Pg. 413 1.1 Diamond Bar General Plan Update Denny's... when we had variety. I would like to see a Trader Joe's or a Sprouts in our area in the next few years. 62. Cut needs its own school district 63. Cut through traffic from other cities, keeping all signage in English language, keeping city more upscale instead of high density eyesore like the Willows development. Keep the wide open spaces that made our city beautiful. 64. DB needs to really improve traffic conditions on DB Blvd. It can sometimes take 20mins to get from Maple Hill to Grand. Perhaps adding a lane and/or work with the State to improve the 57/60 x -change which causes motorists to exit the freeway and use our blvd. We also need more national retain chain stores. Aside from Target and our supermarkets, we have to go out of town to shop at national stores. No more Asian markets or stores. Please try to lure more restaurants like Chilis and more stores like Target. 65. DB should go back in time & be a quieter place to live. I am opposed to growth because of the traffic problem. 66. Demolition and adjustment of older communities, so vacant areas can have suitable facilities for the development of community culture, such as shopping districts, leisure and entertainment centers, etc. 67. develop more 68. Diamond bar doesn't have many local business but the traffic is really bad on the main service streets during off office hours in weekday. For example Diamond Bar blvd and Grand are the gateway for people living in Chino Hills or a freeway bypass to 60E. The traffic pattern is totally different in the weekend. 69. Diamond Bar is a residential community. Focus should be on improvement of the local amenities needed for a first class residential community. These include many of the businesses we currently have - banks, grocery stores, dry cleaners, hair/nail salons, restaurants, logistics, coffee shops. We need sports facilities/fields to support the physical development of all ages of citizenry. We could use a performing arts center to provide a cultural hub for the community. 70. Diamond bar is already crowded as is. It has everything a community already is. If not, the neighboring cities do. There's no need to develop the little natural vacant land we have left in CA, like the space between DB and chino hills. A city doesn't need to have everything possible thing you can think of. It's ridiculous to create more areas and cause more congestion in the area. Diamond Bar is a great city as is. It has big chains, small businesses and parks. Let's work on making diamond bar an eco friendly city and pave the way to protect undeveloped areas. 71. Diamond Bar is an affluent area, but the social capital of the city is pretty much nonexistent (a problem that affects most Southern California cities). Doing things to increase the social capital would not just benefit the city, but the entire SoCal community as well. 72. Diamond Bar is currently a quaint city but most people have to leave to do anything for entertainment purposes or you have to drive all over the city to get anything done. If we had more focused shopping centers with entertainment, more stores and things to do other than eat I think it would increase the city's revenue and not force people to leave to do things. More people would come to diamond bar instead of drive through it. 45 Packet Pg. 414 Survey Report 73. Diamond Bar needs a parallel road to Diamond Bar Blvd. I wish pathfinder past through the country and met up with Grand Avenue or further (but no need to develop the land behind diamond bar beyond a roadway. We need retain wildlife corridors. 74. Diamond Bar needs a parallel road to Diamond Bar Blvd. Ideally a tunnel under the country from South Diamond Bar over to Chino Hills to alleviate traffic while retaining a wildlife corridor. 75. Diamond Bar still has some open and rural -type spaces within its borders. These areas should remain open! The only development within these areas should be hiking, biking and equestrian trails so the residents of Diamond Bar can enjoy them more. Planting more native trees would also be a good idea in these areas; more oaks. Also So Cal desert trees like the juniper, pinyon, and palo verde would make sense because they require less water. NO NEW HOUSING!!!! 76. Diversity 77. Diversity... especially with restaurants 78. Do a major overhaul of the 57/60 Frwy merge 79. Do something with the KMart area. "No horns" from trains behind Lycoming St make it quiet like Walnut did. 80. Don't cut trees down to the trunk let them grow!!! Encourage home owners to improve their homes lower permit fees! Fix the dam street traffic lights so their isn't such congestion -add yellow left turn lights so you can turn when no traffic. Add a kids water park. No pool add fountains! Plant more trees and flowers!!! Encourage businesses to clean up their buildings or new rebuilds!!! This city looks like 1980's and is falling apart.. Put in car charging stations even if they charge drivers it would help. Basically clean this city up take it out of the 80's 81. Don't have any important priorities 82. Drive thru Traffic needs to be managed. A Unified school district for the entire city. 83. Ease traffic. Beautify shopping centers. Beautify residential areas. Encourage and assist small businesses with staying in the city. 84. Economic development 85. Enforce cc&r codes and traffic regulations with in the city. Some neighborhoods are starting to look like slums. Synchronize traffic signals for smoother traffic flows 86. Enforce existing codes of homeownership & create new ones in the City. New people are moving in and not maintaining their properties causing neighborhoods to look run down and unkempt. This is happening all over the city. I've lived here for 30 years and the shift is really noticeable. Rules are essential for everyone to be happy - people can't just do what they want. 87. Enough with the Asian stores. Banks and massage parlors. 88. Ensuring well-maintained homes (& yards), buildings, parks, schools, businesses. Safety of residents. Small & homey downtown area would be very nice 89. Entertainment because we have to go to other cities for it. 90. Environmental programs 91. Environmental sustainability 92. Fix lam traffic 93. Fix the traffic problems. 46 1.1 Packet Pg. 415 1.1 Diamond Bar General Plan Update 94. Focus on North Diamond Bar. The business on that side is lacking. Current businesses are hurting. Attract new commercial developers. 95. Focus on reducing traffic which means no new development - period. 96. Forbid signs from not displaying English also, limit the number of ethnic businesses, attract more diversity, have a police department. 97. Gender 98. General appearance of community such as homes sidewalks streets. 99. Get decent retail back in this city! I shop in Brea, Chino Hills, and Walnut! I was glad to get Smart and Final, and Walmart market, most of the sit down restaurants that served American food are gone. I do not want fast food for breakfast. Too many ethnic restaurants. 100. Get rid of Asia pregnancy homes in Diamond Bar. 101. Get rid of golf courses and build large American shopping stores & American -chain restaurants, movie theaters. 102. go green, art center 103. Green areas, trees, sustainable use of water and power. Better traffic control in residential areas near schools. Reduce noise levels in residential areas near freeways, shopping centers and shopping centers. Public Electric Vehicle charging stations near shopping and dining. 104. Green scapes and bike paths 105. Have its own shopping area. 106. Have the current walmart super market move into the old kmart space next to the mcdonalds so it can be a full store 107. Home maintenance and family life/entertainment. I love the schools in Diamond Bar but I don't like that most neighborhoods in Diamond Bar have so many homes that are unkept. I am surprised that million dollar homes by DBHS are right next to houses that look like a dump. This city is expensive to live in, but yet there isn't anything exciting in Diamond Bar. Improve the parks, get new play equipment, and add places we can go to spend our money to enjoy life with our families. I don't want to go to Brea or Chino Hills. I want to spend my money in Diamond Bar. I want to retire in Diamond Bar, but I don't want to be bored in my city. I want to go for long runs and walks with my kids, but the trails have all these dangers. What else can you do to help residents feel safe in the trails? Please get rid of all the dead shopping centers. Enough tutoring centers. Seriously, can we get a really nice El Torito with music and a bar and dancing? Can we get some kind of Mexican food restaurant that's a little upscale? Not expensive, but you know a place that has a Sunday buffet and music? 108. I don't know 109. I don't think they have anymore issues. 110. I feel very strongly that the Tres Hermanos land and the golf course should NOT be developed. Diamond Bar used to have a slogan "country living". It now feels already too crowded, we're losing our green space, and there is excessive traffic. The 57/60 fwy interchange is one of the worst in So. Calif. and our city cannot handle any more housing. Diamond Bar Blvd and Grand are clogged with traffic from 2:00-7:00 every night. To go 2 miles to store takes 20 minutes. NO MORE BUILDING! I feel like the city is not only losing it's charm, but is actually bursting at the seems. Keep Diamond Bar Green! 47 Packet Pg. 416 Survey Report 111. I have lived in Diamond Bar for 30 years and it becomes increasingly difficult to support businesses since there are so few. We have to travel to Brea or Chino Hills- we have so few family places to visit. Not enough shops or entertainment. The area past Sunset Crossing needs to be developed. 112. I think that DB should create it's own mall 113. I think we should make Diamond Bar more pedestrian friendly 114. I'm not sure 115. I'm sick and tired of the city adding more housing, not adding a VARIETY of restaurants, having NO entertainment at all, and not doing anything about the traffic. WE DO NOT NEED MORE HOUSES. Traffic is bad enough with you guys not doing anything about the congested roads. How can a city not have any sort of entertainment? Diamond Bar is basically greenery and houses. THAT IS IT. Stop spending money redoing the same roads over and over and trying to make more beautiful. It already is beautiful. You've attracted the population you need to. How about you do something about KEEPING the population now. 116. improve freeway so thru traffic stay ther 117. Improve park facilities that already exist. 118. Improve restaurant variety and night life 119. Improve school performance for PUSD 120. Improve the aesthetics and appeal of the housing area north of the 57/60 freeways including enforcement of CC&R. Currently there are homes with broken down cars and front yards that have never had grass or other plants. It looks trashy and judging by the lack of responses by city departments over the years to complaints it appears the city does not care. Why some departments even exist is something I have often thought about. 121. Improve the traffic flow along DB Blvd, from Brea Canyon, to Golden Springs 122. Improve traffic congestions on fwy's and streets. With all new developments water should be a first consideration before any new construction. 123. Improve traffic enforcement. Improve traffic congestion. 124. Improvement of existing shopping centers. The city's beauty is in the open space, trees, small community feel. To preserve that, no new houses or buildings should come into the city. Rather, focus should be put in upgrading the existing shopping areas - many are outdated. 125. Improvement on fencing through our the city the hill sides cleaned of dead brush along grand. Enforce clean up regulations. 126. Improving and adding businesses in vacant and older plazas not often used, more chain/popular stores and restaurants needed 127. Improving safety. Too many stories of theft and robberies. Also, how to better manage our wildlife. Coyotes becoming a major issue. 128. inspire the new generations to be creative 129. Install lighting (traditional or solar) at stairs and trails in Sycamore Park. I run at that park every day. It is hard to maintain my routine when Daylight Savings makes it get dark early. Also, when tax season rolls around, I don't get off work until dark. Would be nice if trails and stairs were lit up til lopm (like other parks in DB). 130. It's my understanding that renovation of the village area at golden springs and diamond blvd. is in the planning stages. I propose that in the middle of the area, the city relocates the 48 1.1 Packet Pg. 417 1.1 Diamond Bar General Plan Update windmill from uptown and places it within a circular design adding a round flowing fountain for the public. It can be seen from the 60 freeway and will form the focal point for our city! 131. Job employment 132. just add more restaurants and shops 133. Keep Diamond Bar a safe and great place to raise a family 134. Keep diamond bar safe small town great to raise a family Diversity. There is. It much diversity any more 135. Keep it as it is, no need for improvement for housing, fix traffic congestion 136. Keep it green 137. Keep open space, open. No more unnecessary housing in undeveloped areas. Use areas like golf course where land is underutilized 138. Keep open spaces as is, remain true to the old spirit of Diamond Bar before it was even incorporated. Leave the open space between Chino Hills and D Bar as is - it reminds one of Switzerland every time one drives through that area. Make a "town" place or city center which can bring revenues to DBar and attract people of the city to hang out there as families, and in the evenings a place for younger folks to eat out (new restaurants?). NO new housing in D Bar, improve the traffic on DBar Blvd and improve congestion on the freeways. Diamond Bar is home and beautiful, please keep the flavor of old Diamond Bar in mind while making improvements. 139. Keep Tres Hermanos as it is and make it a permanent reservation for animals with no development on it. 140. Keep us rural in outlook! 141. Keeping DB on the top 10 cities to grow a family. 142. L -E -D street lighting Natural and native plants to conserver water And natural park restorations. More like sycomore trail and peterson trail. From what I've seen, they are the most popular nature attractions in Diamond Bar. Not even the regular parks get has much foot traffic 143. Leave the Tres Hermanos land as is and add more entertainment in Diamond Bar 144. Leave tres hermanos alone! ! ! 145. Leave Tres Hermanos alone. If anything make it so once a month people can take a guided nature hike to respect nature. Also as far as the parks the baseball/softball fields it would be nice if there was awning, it gets very hot and a lot of grandparents are not able to attend games because of the heat and also the cement "bleachers"at pantera are ridiculous for old people 146. Less asian noodle houses. Seriously. 147. Less dense housing 148. Less ethnic restaurants. Traffic on DB Blvd. better grocery stores. 149. less water usage 150. Livability above all else. Leave Tres Hermanos as open space. Developing it will destroy the spirit of Diamond Bar 49 Packet Pg. 418 Survey Report 151. Looking for a shopping center similar to chino hills the shoppes or Brea new Valencia center 152. Mainly street congestion and more family friendly events. Also more chain restaurants and stores 153. maintain a clean city. I see workers cleaning freeways, street. It should stay same 154. Maintain Diamond Bar as a quite, calm, safe town. Increase in congestion and traffic has ruined what Diamond Bar truly was. Please keep the greenery and landscape intact, without destroying the natural scape to build homes/apartments/tow homes. 155. Maintain low crime rate... burglaries, murder, ect. More family events/activities provided or offered by the city. 156. maintain strong financial prudence to ensure ability to maintain current level of service during financial downturns. Create more office buildings in the Copley area to generate more taxes and bring people to our shopping centers and restaurants. Continue to be senior friendly with services 157. Maintaining and improving parks, trails, and green spaces 158. Maintaining our open spaces and increasing public access to these outdoor resources. 159. Major restaurants. 160. Make businesses (big and small) stay in our city to create jobs and more revenue for our city. 161. Make Kmart lot and store into a downtown hip and trendy spot 162. Make more hang out places, food places 163. Make North Diamond Bar equal to South Diamond Bar 164. Make sure sidewalks are federally compliant. There are parts where there is barely a foot clearance which does not comply with ADA standards. 165. Make the area between Chino & DB a national preserve!!!!! 166. Make the city look nor consistent from North to South. 167. Making city more environmentally friendly- using solar, wind energy. Making alternative fuel vehicle charging stations available throughout city. 168. Making Diamond Bar a place to live and work/no need to commute to other parts of LA 169. Maternity homes people from other countries 170. Minimize the growing traffic on Diamond Bar Blvd. We should not be a "pass through" city. Upgrade old Condos, remodel existing antiquated shopping areas, and divert traffic to Chino Hills through Tonner Canyon. 171. more activities and entertainment 172. More American friendly places instead of mainly Asian inspired 173. More and better markets to come to Diamond Bar 174. more area for people to go to the park and for health working out 175. more bike paths and hiking trails. 176. more breakfast restaurants. American foods, more diversity 177. More development; keeping DB green; Stricter renting restrictions to keep out 178. More dining and entertainment options please --on par with Brea and Chino Hills. 179. More diverse restaurants, not only Asian restaurants (as much as I love Asian food) 50 1.1 Packet Pg. 419 1.1 Diamond Bar General Plan Update 180. More diversity in the area of diamond bar is needed. There are too many Asian restaurants and our area is becoming less and less diverse. We also need a movie theater and a place to walk around such as the shoppes in chino hills. 181. more entertainment 182. More entertainment and shops 183. More family entertainment. Outdoor mall. Movies. Etc. 184. More family friendly entertainment. I would love to keep my business in DB. We need a sprouts or trader joes 185.

More maintenance for older overgrown areas of the Cityscape and neighborhoods 187. more parks 188. More parks. Current ones are over crowded 189. More restaurants 190. More retail and restaurants 191. More shopping, parks, amusement parks, athletic centers 192. MORE SOCCER FIELDS 193. More stores 194. more things to do, better entertainment 195. More traffic enforcement on surface streets. 57/60 frwy Interchange debacle. 196. More trails. More parks. More open space. 197. Need more family restaurants. Would like a Trader Joe's or Whole Foods 198. Need things to do here. Have to leave town for 'better' restaurants (non Asian), for a movie theatre, for a playhouse. No place to walk to shop, sit at a restaurant with outdoor patio seating, no shops for artwork, nothing to keep me here to contribute to our community. Again, there is NOTHING to do here! First we need TRADER JOES! Not another Walmart or Kmart or Chilis chain! More upscale restaurants, Yardhouse, Italian, steak, night clubs for dancing, live music, blues or country, we need things to do!!! 199. need to have additional restaurants that are American. we continually have to go out of town for meals out. work on giving incentives to the home owners to maintain their properties (get rid of dead product in yard) enhance the outside of buildings in Diamond Bar. We just have an old look- we need to modernize. 200. New stores/entertainment 201. No more DOC, kids should attend school near their own homes. That solves traffic on streets and fwy. More dining and shopping options. 202. No more housing Preserve as much land as possible 203. No more housing, keep land between chino hills and DB as is. Performing arts center in Industry off Grand, mid sized retail, Grocery and restaurants. 204. No more housing! Fix 57/60 interchange (already most congested in US) 205. No more mansions that destroy hill top ridge lines! Install DB municodes to truly protect California native trees/oak woodland; monitor & support wildlife connectivity. Conservation of hill tops, city trees; eliminate invasive plant species (palm trees). 51 Packet Pg. 420 Survey Report 206. No more new housing! 207. No new housing; roads including freeways cannot sustain more traffic. 208. no other comments 209. Nothing added commercially near the 57 / 60 interchange at Grand. It is already the worst traffic nightmare. We do not need to add to the congestion in our city. 210. On the intersection of Diamond Bar and Grand Ave, there was construction a few months ago. This caused so much traffic that it was just dumb, and for what, tiny decorations in the street dividers and on the side walks? Better ideas that do not mess up traffic. 211. Open land should remain open. No more housing. 212. Open space quality of life resolve traffic more shops 213. Our city needs to be planned with sustainability in mind. We need water harvesting to be incorporated into city buildings, our city hall needs to be an example of thriving healty ecosystems. We need plant more trees, thinking about a composting system to reduce waste citywide. We need a community farm, local food and cottage industries need encouragement. Farmers markets, night markets, local products. The Kmart center could be redesigned into a community space, lots of mom and speciality shops, great restaurants, organic foods, farm to table restaurants, bread bakers, organic coffee shops, craft beers, butchers. Think small, wholesome. Night music, fountain. Shade trees, night walking areas, places where people can meet & greet each other. 214. Our main long term goal should be maintaining the balance of nature and city life that we currently enjoy. 215. Over crowding and traffic are the cities main problems 216. PANTERA PARK too crowded during field games. Not enough parking spaces. The restrooms now dirty. DBar should stay quiet and not busy. 217. People should issue the cramped space of Diamond Bar. There are too many buildings that are placed too close together. 218. Places to eat & shop for the non asian population. 219. Plant trees and don't butcher them down. Drive and inspect homes and businesses to clean them up so many places look like there falling apart. Allow -encourage tear down and rebuild of the old shopping centers and restaurants! Mandatory public car charging at public places doesn't have to be free they could charge but would be a great thing. Let someone build a high rise building skyscrapers type. Replace lights to LED. 220. Plaza near KMart 221. PM traffic on surface street (diamond bar blvd & grand) as shortcuts for non city residents 222. Possibly get it's own Police Station? 223. Preserve natural land. 224. Preserving diamond bars peaceful and relaxing atmosphere. Wide streets hidden communities and town centers with good food 225. Preserving the "country" way of life. Peaceful open spaces. Address the traffic concerns with all the new development. 226. Preserving Tres Hermanos Ranch if possible. Creating a downtown/city center area to become the heart of the city. Focus on transportation alternatives to heavily trafficked areas (new shopping centers @grand/57, Mt. Sac., etc. 52 1.1 Packet Pg. 421 1.1 Diamond Bar General Plan Update 227. Preventing the overcrowding of the city due to increasing housing builds. We already have a lot of houses on the market and/or are abandoned and we should fill those before we make more housing. 57/60 freeway traffic is still not safe to drive through, the merging of two major freeways is still a big concern. I would like to see untouched land remain untouched as it should remain more family suburb friendly than busy city. I would also like to see more family fun entertainment in the city 228. priorities would be helping Diamond Bar become a more innovative and fun place to come 229. Protect the Wildlife. 230. providing amenities and services for seniors 231. Public safety: It is an expensive proactive insurance policy that must be maintained. Our fire and paramedic staffing levels have not changed since 1989. Yet the demand for service increases each and every year. Our population is aging and the 911 system is now considered a first line to healthcare. We do not have an Advanced Life Support unit stationed within the city limits. Most do not know this. DB relies on Rolland Heights, Walnut and Pomona for these units for life saving services. In an emergency time is everything. Most of DB's crime is not committed by DB residents. Two points here; One, increase sheriff staffing with units assigned within DB city limits. Two, low income housing within DB will guarantee an increase in crime. Don't let the state bully the City into it. We all will be sorry for it later. Never spend more than you make. DB has always been financially responsible largely to the fact that we are a bedroom community and that's okay. Let's not be something more then we are. 232. Public transit- our bus options are limited to once/ hour on DB Blvd. It takes my son 3 hours to get to Mt.Sac and 3 buses. We need to improve this transit connection between Chino Hills and Walnut via Grand 233. Public transportation would be a lot more convenient if there were less congested streets and safer cross walks 234. Reduce freeway congestion, fixing 57/60 interchange, reduce congestion on Diamond Bar Blvd. 235. Remain beautiful, security 236. renovate existing storage fronts, provide more new "town center" type areas close to freeway access, and build better medians and decor on north diamond bar boulevard. 237. Rental homes and poor upkeep. Strengthen code enforcement. Encourage beautification of older neighborhoods. Replace or enhance retaining walls in older neighborhoods. Improve community unity and respect between north and south Diamond Bar. Improve sidewalks and replace trees on Golden Springs between Diamond Bar Boulevard and the 60 freeway. Resolve the decline of the shopping center at the corner of Diamond Bar Blvd. and Gilden Springs. It's an embarrassment. Bring in restaurants from a wider variety of cultures. Italian, traditional breakfast, good Mexican, etc. Encourage and promote taking care of property including low water landscaping. 238. restaurants 239. Revitalize present shopping centers 240. Safe places for children to play; no more strip malls; congestion at DB Blvd & Brea Canyon 241. safer transportation 53 Packet Pg. 422 Survey Report 242. Safety from coyotes, help emerging homeless population, proactive recycling and air quality program, Diamond Bar police force. 243. Safety housing 244. Safety, keep bad people out. 245. Schools (3) 246. Senior citizens services 247. Separate 57/60 248. Shopping centers 249. shopping centers in diamond bar 250. Similar to Brea, require more public art and public gathering space as part of any development project or renovation. It really adds to the culture of the city. 251. Simple and secure place to live 252. Small Business development 253. Small downtown area with national restaurants, retailers similar to Shoppes in Chino Hills is huge need. We don't want to drive 20 minutes to Brea or Chino Hills in traffic to do our shopping and dining and we don't need another Pho restaurant or Korean BBQ. Also, I would hate to see the area between Brea and Chino Hills developed especially for more housing. Traffic is already terrible at the 57/60. I love that Diamond Bar has invested in updating trails and dog park. 254. Smoking/tobacco in multiunit housing, and public areas. Better enforcement of speed limits on diamond bar blvd., golden springs. Dr., and other major streets. 255. Some type of trash and litter clean up, lift the ban on using signage of a reasonable size for advertising services andmore services for seniors. 256. Stabilize and improve the transportation corridors to reduce the through traffic on DB streets. 257. Stop kids from jaywalking, clean general city trash, stop spending money solely on beautification purposes 258. Stop taking yard sale signs down. You are purposely working against us. Residents enjoy going to yard sales. Take down old political signs. More trees on residential streets. 259. Street traffic congestions, street beautification projects, plant more trees to ease pollution. 260. Street traffic, working hours 261. take care of the traffic 262. The biggest problem is over -built commercial sites --virtually every one, except the Gateway Center --and inadequate parking. It's why I do most of my shopping in San Dimas, Chino Hills and Brea, instead of here in town. Aside from limited options in Diamond Bar, the parking situation is a nightmare. 263. The bike lanes in Diamond Bar are too wide. They need to share with vehicles. Bikes commute 1 person, cars commute multiple people in the same road space. 264. The city is in a great location with lots of pass byer but no major attraction for shopping, food, family entertainment. Transportion(light rail between major hub/intersection), traffic congestion, public parking structure and public safety 54 1.1 Packet Pg. 423 1.1 Diamond Bar General Plan Update 265. The city should focus on preserving our hills and green space in the city. We don't need any more development. The traffic is bad enough. 266. The drugs 267. The General Plan needs to prioritize environmental conservation of our open space and wildlife, and create more parks for residents. 268. The General Plan should issue the traffic before and after school. 269. The main concern I would have is that there are limited ways to enter/exit Diamond Bar (Diamond Bar Blvd, Grand Ave, Temple Ave). When the freeways become congested, it overflows to these streets, making traffic worse. Improving the 57 and 60 may help alleviate this problem. 270. The school districts of gifted classes should be set; shopping mall 271. The traffic 272. The views from numerous home sites and streets are being blocked and ruined by the over growth of trees which go untrimmed for decades. It is detrimental to home values. Also one good fire and the flames will spread rapidly. Trees should not be allowed many stories above the roof line. 273. There needs to be a dedicated effort to attract stores and shops in a downtown similar to Brea. 274. They need more homes because there are many people that don't have a shelter. They might die. 275. They should make more sports 276. To allow for more businesses in the city through fewer regulatory actions and more incentives. 277. To be continue a safe city; to be continue a green city as now; to be continue a better activities for citizens 278. To have own police department, one Diamond Bar School District, a major shopping center that has multiple retail tenants to anchor super center, improve public safety with video camera in high crime areas, install LED street lights, enforce landscaping rules to improve city image, and build senior housing to replace all HOA club houses including eliminating all HOA fees for the residents. 279. To not develop one lands that contain wildlife. To preserve nature and wildlife in Diamond Bar 280. To secure non potable water sources for irrigation. Develop or build in commercial areas that are not being used right now. Renovate or build new business places where current one are antiquated and not being used. 281• Too many stores on the North end of Diamond Bar are vacant. The North end looks run down compared to the south end that caters to the country look. Please beautify this end too! We love our city too! 282. town center (2) 283.

Traffic is the biggest issue and it keeps getting worse 289. Traffic is the biggest issue in Diamond Bar. 290. Traffic is the biggest problem and it is only going to get worse. New housing should not be allowed because of the drought. 291. Traffic is the main issue. fix both directions. 57 fwy 292. traffic on DB Blvd. 293. Traffic on grand and diamond bar 294. Traffic, crime, senior housing 295. Traffic, new revenue for the city, redevelopment of properties don't let them sit vacant for years making them eye sores. Don't divide us make Diamond Bar all one community with good schools on both sides and property values the same. 296. Traffic, retail stores 297. Traffic, traffic, traffic and build a mall/entertainment/restaurants on grand near freeway 298. TRAFFIC!!!!! We've lived on the very south end of DB for 18 years, and the traffic on DBB north after 3:00 PM on weekdays has become horrendous. It can take 30 minutes to get from Cold Spring to Grand. If it is possible, make Brea Canyon go straight through to Brea Canyon cutoff. If not, we need more than two main streets through DB (DBB and Grand)! 299. Traffic. More family oriented gathering areas. Places to walk around and browse or sit and listen to music and have ice cream or coffee 300. Trail system 301. transportation 302. Transportation congestion, affordable housing, and good hiking trails. 303. Tres Hermanos land good for a huge park for field games. Pantera Park get crowded and no place to park for us. We need patrols in the park due to too many dogs unleashed. No one using the Bark park. 304. Tres Hermanos should be a ranch amusement park or state park 305. Tres Hermanos should remain open land or as a park (possibly annexed into CHSP.) 306. Tres hermanos. Open a road. 2nd exit. 2 DRHS. And event/concert facility. And indoor swimming pool For db residents. Fee for other residents neighbors to Diamond Bar. 307. Try And get more sit down restaurants in city 308. Under or over passes at major intersections to reduce traffic More trees more trees, and more trees No more fast food. Downtown should have trees with lights, and walkways, such as Claremont. Frozen yogurt, Sprouts or Trader Joe's, and decorate for the holidays. Parking for shopping should have trees that provide shade. 309. Upgrade improve vacant land near YMCA on sunset crossing. 310. Upgrade infrastructure 311. Upgrading quality of life for residents through building improvements, parks, outdoor community gathering. 312. View lots being blocked by neighbors overgrown trees 56 1.1 Packet Pg. 425 1.1 Diamond Bar General Plan Update 313. We do not need more housing. We need to clean up or modernize existing shopping centers. We need decent parks and trails. Yoruba Lynda has wonderful trails. 314. We have parks but they are too small. So if at all possible expand the current parks and a park whenever available. Is there a way to address the traffic problems on Diamond Bar Blvd ? It should not be used as the alternative to the 57 south. The entire city should be connected by bike lanes and parks. 315. We have to be engaging to the pedestrian. When a person parks their car, we must reduce their need to get back in their car to drive to the next place. 316. We need a "downtown" area, with the Kmart area you had the ability to take the far south end and make a parking structure (behind McDonalds) then develop the property with a movie theater, shopping and food chains. As it is now you are giving the tax dollars to Chino Hills and Brea. When we go the movies we go outside the city for both dinner and a movie. The surrounding cities are making money from the residents of Diamond Bar. I have lived here or had family here for over 50 years. Let's try to keep the tax dollars and spending in Diamond Bar! 317. We need a city ordinance for residence to keep the appearance of their property clean. This city is looking old and run down. The city needs to clean up city trees, bushes etc on all street not just major streets. We are tires of looking at yards that are dirt, dry, old cars not covered, junk collecting in yards. This is horrible. The N. side has been untapped. The city needs to do something to wake these people up to maintain their properties. You can add whatever you want but if properties are trash then who would come? 318. We need a community center that is not focused just on seniors but the younger crowd. Including a recreation center, gym, cultural center, and events. There is definitely too many empty lots and not enough business to generate tax revenue for the city. (for example former Kmart lot and corner of Diamond Bar and Golden Springs shopping center have empty stores.) Also lacking high end stores. (for example Walmart and Smart and Final.) Also not too many stores in Northern part of Diamond Bar near the 60 freeway. Make the shopping centers more attractive to customers and survey to see how many people actually use the shopping centers. 319. We need a good dog park. The one at pantera park is not good it's like it was an afterthought. It's poorly placed. Small and has no natural elements. Imagine walking on that bark in bare feet. It would hurt and dogs paws are sensitive too. Also there are snakes in the area that make it dangerous. I would love to see a well planned safe dog park in diamond bar 320. We need less congestion on Grand and DB Blvd. Santa visits or letters to kids at Christmas. Kids handprints at parks for decor. Bathrooms at all parks. Indoor basketball gym for public use. Public pool with low fee. Christmas tree lighting ceremony at a local shopping center with activities. 321. We need more diversity in restaurant choices. 322. We need more entertainment 323. We need our own police department that can enforce traffic safety especially during rush our. People drive very recklessly and we need more of a police presence to save innocent lives from these reckless drivers. The 60 to 57 transition situation also needs serious attention. We need to either force the state to rectify this or generate income by ticketing these reckless drivers. 57 Packet Pg. 426 Survey Report 324. we should do something with the vacant land between Diamond Bar and Chino Hills. During most of the year, it is brown which makes the entrance to Diamond Bar not so appealing 325. Would like to see more mainstream stores come into our city. Have to go outside city limits just to have a typical American breakfast or shop or go see a movie. I would like to see more diversity that better reflects everyone who lives here. I don't want to live in a city that caters to one race or culture. 15. If you would like to provide any more detail or clarification on any question or topic, please do so here (134 Responses Total) 1. As a swimming enthusiast, the community pool length does not meet the fitness and exercise needs. 2. 2. Planned, thoughtful development of commercial, light manufacturing and professional facilities, in coordination with major companies, that serve to reduce the percentage of DBar residents who commute long distances by instead giving them places to work within or near the Diamond Bar community. 3. Add speed bumps/humps or other traffic calming tactics near Pantera park. 4. Adding more lanes to Diamond Bar Blvd or Grand will not relieve congestion. It will make it worse. We instead need to relieve congestion on area freeways so commuters do not use DB roads as freeway escape. Likewise developing Tres Hermanos will ruin what's left of Diamond Bar's livability. Will create more traffic and congestion and reduce property values. The hills of Diamond Bar are what gives this city its character. Paving them over will benefit only developers and harm everyone else with decreased livability, more congestion and longer commutes. 5. All parks will upgrade to make a "theme park". For example, Cherry Blossom in spring for one park and Canadian Maple in fall for another to beautify them so we can outdone all other cities. 6. As a forty-six year Diamond Bar resident, I feel afforded the viewpoint that others may not have. I was born here, educated here, employed here, a homeowner here, married here and am raising a family here. I am proud of our City. Thank you for the opportunity to share my thoughts. Respectfully, James M Golondzinier 909-632-8113 7. As our community ages, we need property improvements to maintain and increase property values. 8. Be true to the city's spirit and flavor while making any needed improvements. Please leave the open spaces between Diamond Bar and Chino Hills as is - No new homes. New restaurants and shops to attract more revenue. Improve transportation making it easier for people to commute by public transportation if need be. 9. Build a indoor swimming pool For the residents. 10. Build Costco 11. Build more local options for public transportation that brings you to pedestrian only downtown center 58 1.1 Packet Pg. 427 1.1 Diamond Bar General Plan Update 12. City parks, midways and businesses are well maintained. I appreciate the efforts the city in to dealing with drought while. Ain't aiming the essence of Diamond Bar. sadly many homes in our neighborhood (Chaparral MS) are in dire need of paint and landscaping. Many are rentals now which means that we are headed for further decay. 13. Correct traffic issues like Brea Cyn Rd between 60 freeway and metrolink station. Example; people use right lane as two lanes approaching freeway. Haven't seen a single ticket issued in the entire city in months. People doing 70mph on Diamond Bar Blvd. 14. Diamond Bar has become too saturated with Asian dining, shopping and business options. Residents have to travel to Chino Hills, Brea or Walnut to find diversity, therefore spending tax dollars elsewhere. Other than Chili's or The Whole Enchilada, there are only Asian dining options. 15. Diamond Bar is becoming increasingly busier and busier. This would be fine if the street lights were upgraded with smart cameras that control the flow by need not by timers. driver aggravation as well as smog levels would be reduced if light changed in a more efficient manner as if an old-time traffic cop was monitoring flow. Technology can certainly be of use here. 16. For the empty land which between Chino Hills and Diamond Bar, I think we should develop half of the land, and for another half, we should keep it natural. 17. Give the community more so we continue to want to live here. 18. Given new housing in the city, new traffic studies need to be made to update traffic signal behavior. 19. Going back to question # 11,1 would like to see the Tres Hermanos Ranch remain open space as an extension of Chino Hills State Park, or a regional park for DB and Chino Hills residents. 20. Good thoughtful long term planning. Thx 21. Having an entertainment/food area would save me a lot of time of going to neighboring cities (i.e. Brea, Brea Downtown, Chino Hills, etc.) plus have more tax dollars for DB 22. How profitable is the golf course and the Tres Hermanos field? 23. I am not a big fan of putting up more hitching posts for millions of dollars. That money could be better spent on youth sports. 24. I answered the housing and commercial development questions based on the options available. After thinking about the follow up questions, my preference would be to redevelop empty shopping areas (e.g. K -Mart) into new commercial or housing areas. If the golf course is fine, it should stay. A town center or downtown can help create a feeling of community. 25. I call the city pretentious in the first question because I work retail in Diamond Bar and many of the customers demand high class service while being trashy themselves. 26. I can provide specific addresses of the lack of care about the proper care of homes now lacking. 27. I do not support additional residential or commercial development. D.B.is losing its small town feel. There is too much traffic. 28. I hate how our city is becoming a CONCRETE JUNGLE and major TRAFFIC CONGESTION. WE HAVE ENOUGH HOUSING so please stop building them. Please focus on improving the natural scenery with trees, grass, flowers, etc Please support current 59 Packet Pg. 428 Survey Report businesses make money by supporting them by allowing certain features. We are bummed that the double bus seating for a sandwich shop wasn't allowed. We are bummed that the city won't allow its existing resources to let small businesses advertise. 29. I have loved in Diamond Bar 44 years, it would be great if the original "country living" was true, but since progress has moved it beyond that, make it a place we want to shop, eat, play, enjoy. 30. I like being able to see hills around the city. I enjoy the hiking trails and the "small-town" feel. I am against further development and additional housing projects. 31. I like DB. I have lived here 28 years. Let's keep crime down. Don't destroy nature. Don't over build and I have no idea why you destroyed that land off of grand but it's an ugly mess. If you over do it with stores and entertainment and don't take into consideration the traffic DB will be a miserable place to live. 32. I moved to DB because of the open space. I pray we will not lose the country feel. 33. I realize that the population of DB is becoming quite diverse and with it there are many different cultural practices, but if there is not any standard conformity rules then the neighborhoods will become very unsightly. An example is the location of trash receptacles 34. I respect our Asian community but feel that it only caters to them. 35. 1 support the development of a sports park. We do not have enough sports fields for the number of children and teams that need to practice. 36. I think the North end of Diamond Bar should have the nicer traffic signals and crossings like the south end has received recently. I also think the walls on the north end should have wrought iron just like the south end. Also think the hills lining Diamond Bar Blvd. on the north end should be landscaped. not just dirt. 37. I think the residence of north Diamond Bar are neglected and we could use the area beautification the same as the rest of the city 38. I was at the community workshop and was disturbed but not surprised to see that the median age was about 55. 39. I would hope to see the tres hermanos land be kept as it is. I don't golf but understand that many people like it, though I feel some/most of that land can be put to much better use. The more nature the better. 40. I would like the keep DB family oriented. I do not want to see any more housing. Vacant buildings should be utilized first before new ones. More housing, more people, APARTMENTS- higher crime rate. 41. I would love to see a pedestrian bridge built crossing DB Blvd. at Syc Cyn Park to access Steep Canyon and on to the trail there. 42. I'd love to see a walking trail behind the homes at the west end of Morning Canyon Road, such beautiful sunsets, but we need a public easement to pass onto the land that isn't used. 43. I'd really like to have a city center or downtown where there are small streets and activities can be chained together. For example, see a movie then walk to a restaurant. 44. If the golf course is moved, don't convert the land to more homes. Use that land for a Great Park with updated soccer and baseball fields for youth. Kids are leaving Diamond Bar for baseball, football, and other sports to Walnut and Chino Hills. 45. Improve traffic on major streets and fwy leading to diamond bar. 60 1.1 Packet Pg. 429 1.1 Diamond Bar General Plan Update 46. In door recreation 47. It would be nice to have a small but nice open center like a small version of the park in vegas at park Ave and las Vegas Blvd. It's beautiful and serene but has places to eat and things to see. 48. JUST DO IT 49. Just work of plant growth and native growth. Look at Beverly hills. Trees, Nature and Hikes everywhere. I know we have the potential. We are a great city! 50. Keep D. Bar as is and preserve its prestige. 51. Keep DBAR quiet and not busy. Small neighborhood parks like Pantera should not be as crowded as it is right now. Our early evening walks no longer leisurely as it used to be. Don't build on Tres Hermanos land. Put a huge Park instead for field games, picnics, trails. 52. Keep it small & simple ... no overcrowding. 53. keep the city clean and beautiful. 54. Kids athletic fields 55. Leave tres hermanos alone, please save what little open land L.A.county has left. 56. Leave Tres Hermanos alone, there's too much traffic now and the hills should stay for its beauty and a place for the wildlife we keep encroaching on. 57. Let's model Claremont, Altadena, Pasadena, we need more life in Diamond Bar 58. Maintain and upgrade city's street appearance with regards to plants, trees along with utilizing vacant buildings, ie. the old Kmart center in a manner that will improve the city's appearance and finances. 59. Make the trains quiet "no horns" like Walnut that are behind Lycoming St 60. Many of the area's rolling hills have been stained with housing and other developments. Let's keep those areas clear for trails and wildlife. 61. many roads should be widen 62. more entertainment 63. More national sport team 64. More safe neighborhood and organic supermarket in our community 65. Most shopping complexes have become old, look outdated and dirty. Sprouts would be a huge asset to our city. The parking lots are unkempt. More trees would help keep the city cool and provide fresh air. Artificial turf increases the heat in the ground and should not be allowed in public places. We love living here but it is getting crowded with a certain demographic of people. Stores should have signs in English with products on shelves having English descriptions. Traffic rules need to be enforced with clear signs. Head beams should be banned. 66. movie theater! 67. My family really wants to enjoy the city but we feel like we can't. We really need a place to be entertained. We need lively places. Get rid of the old stores that are dead, or that keep their hours of operation very limited. Why is this happening? Diamond Bar feels dead, and that doesn't make me proud. 68. My interest in the plan is to encourage conservation of our unique open spaces, and expand our park areas to enhance our lives in Diamond Bar. Tonner Canyon is home to endangered 61 Packet Pg. 430 Survey Report species and is an important wildlife corridor. Citizens do not value this local resource enough because it has never been open to the public. Rather than looking to build in new areas, we should focus on ways to enhance or improve what currently exists and in need of an upgrade. 69. Need a larger variety of American restaurants. Not just Asian restaurants. No early breakfast places to eat before going to work. Open at 6AM. 70. No more Asian restaurants. We must cater to the multiple cultures in our great city. 71. No more housing 72. No more housing. There is way too many ch congestion. And we need the old Kmart lot developed with dining and entertainment options. Please also consider getting rid of the seedy hotel near that same lot. It breeds crime. 73. No new developing housing in tres hermanos. The city looks run down and old. We need ways to make it inviting to live in. Draw in new higher income home owners. 74. Once more ... get rid of the village area and provide new buildings similar to those in Phillips Ranch, Chino Hills or the Spectrum areas. It will draw attention along with new business opportunities and will provide "new life" to existing businesses. The added windmill and fountain area surrounded by tables, chairs and umbrellas for eating or relaxing after shopping, will greatly enhance our city! 75. One other issue is the North Orange Crush Interchange to the 57/60 Fwys. The 57 Fwy needs to go straight through without merging into the 60 Fwy the way it is now. It creates a nightmare on the freeway and city surface streets. 76. open a bar 77. Open space issues is a must for future generations to enjoy 78. Open toner canyon for cars so we can stop people from driving thru DB 79. Our city has banks and grocery stores. If we are to shop in town, we need clothing, accessories and other types of retail businesses. 80. Parks are perfect the way they are. No need for additional improvements 81. Please consider additional family friendly events with local vendors during winter time at a local park or school, low admission price and free movie. Involve local restaurants to sell food, crafts, games, churches etc. 82. Please stop trying to increase the cities population density. We're rapidly becoming an over crowded mess of a city. 83. Please, no new housing. Let's re -plant and tend and beautify the open spaces we have and make them available for all to enjoy. 84. Preserve/restore the struggling, remnant existing natural resources (wildlife habitat, trees, hillsides). Presently, DB municode 22.38.060 #8 erroneously allows for destruction of coast live oak woodland, violating California state law SB 1335. Diamond Bar needs a specific Oak Tree Policy protecting riparian, coast live oaks. Coastal sage and cactus scrub habitats MUST be acknowledged in the General Plan, as they are host to rare and endangered birds, mammals, insects. Ecosystem services should be detailed and valued in the General Plan. Properly conserved, Diamond Bar historic native landscapes are unique and a key characteristic of the town, which could draw environmental tourism and provide economic sustainability as well as fine cultural arts. Plein air painting, Cal Native gardening, classical 62 1.1 Packet Pg. 431 1.1 Diamond Bar General Plan Update music concerts, youth nature discovery programs and more, would make Diamond Bar an exceptional destination IF conservation of native wildlife habitats scored consistently with industry standards. 85. Regarding #13: Seriously, preserve Tres Hermanos and Tonner Canyon! The open spaces were the places our neighbors, friends, and family gathered when I was growing up here. I'd love for my family and my neighbors families to have that same experience. 86. Restaurants - family owned, independent. no need for fast food restaurants. No need for downtown, too much traffic congestion. Better to have it spread out in area/city. Traffic - sync the stop lights at major intersections that make common sense especially at DB&BreaCyn. #11 Be nice to have bike trails. Add other retailers like TJ Maxx, Ross, or Home Goods at former K -Mart location. 87. See previous question 88. See what the following cities have in common and try to emulate them. College Park, MD Austin, TX Cambridge, MA Providence, RI Portland, OR Ann Arbor, MI Madison, WI Boulder, CO Berkeley, CA Ithica, NY 89. Something needs to be done about the traffic. Stop spending money on beautification projects, and start spending it on traffic improvements!!! 90. Something needs to be done to help the congestion on golden springs. It has gotten worse over the years. I'm not sure what can be done. But maybe a change in green light time and sequence could help. I love living in diamond bar it's such a peaceful place to live and it's location is great. 91. Sometimes when a city grow up in sbres, or big location decrease and quality of life because of security and quality of air and noise 92. sound proofing over passes, too much free way noise 93. Support of neighborhood watches, in the area by the Metrolink station, that gets blatantly ignored 94. Tear down rebuild should be encouraged! That should included homes!!! Or at least remodeling!!! Look at the progress of other cities Diamond Bar sucks and is so old looking and it is a young city but looks so old and rundown. 95. The 57/60 interchange is too dangerous. Too many lanes to cross and the result is a dozen accidents each week. Plus, the 57 south to 60 east connection needs a redesign. You have to exit the 57 freeway to get on the 60 east. 96. The city needs a downtown where families can walk around, eat, and watch movies. 97. The entire Diamond Bar is very populated. In my opinion, there is no need for a downtown because the population resources are already very dense 98. The golf course offer pleasure to many residents & should remain 99. The Intersection at Diamond Bar and Grand is so congested. I'd seriously look to replan this intersection with any new remodeling. Each center needs a stoplight to get in an out. The parking so so difficult to navigate with a full size vehicle. 100. The Tres Hermanos area should NOT be developed for housing. Traffic is bad enough now. A large park area would be better use of the land. If water and drought are problems now, then adding a large number of new houses would be irresponsible. 63 Packet Pg. 432 Survey Report 101. There are too many old structures (strip malls) that are not improved and look awful. It seems like there's one on every corner and many of the businesses are out of business causing blight. Also, building projects get started and never get finished causing fences to go up around a mound of dirt. The city needs a total rehab. 102. There is no much to clarify except to use some of the very best cities around the country as an example. The problems are the costs, time, and the citizens agreed to take steps to make City of Diamond Bar a better city in the next 20 years. 103. There is no where to have fun 104. There is really no big park in the city. It would be great to turn the golf course into a big park or a downtown. The golf course is really wasteful of land and space. Not to mention all that water for the grass. 105. There should be more places to eat wherever you are. 106. This city is boring and old. 107. toll fees for none resident traffic 108. traffic - public transportation 109. Traffic is a big problem around schools currently. Drivers dropping off their children and causing massive congestion and safety concerns. (parents cutting off other parents, dropping off children at non -designated zones) 110. Traffic is at a standstill as it is. We need to take care of present problems before adding more housing and more traffic problems. 111. Traffic is becoming worse with more drivers cutting through our city on their way to Chino or Pomona. An under or over pass at major intersections will help. Widening the streets has not. 112. Traffic must be addressed in the general plan and development of housing should be curtailed because new housing produces new cars. 113. Traffic, traffic.... 114. We could certainly use a more diverse shopping experience, not just grocery stores. 115. We do need a more diverse option for dining. There are too many Asian places. I would hate for our city to turn into another Rowland Heights. 116. We don't need another dog park. Everyone has a backyard and besides, its rarely used and taking lots of space. 117. We don't need shopping places. We are surrounded by neighbor cities field them. We can keep DBar unique with its bedroom atmosphere. 118. We have lived hers 39 years and have seen communities around us grow while DB seems to have stagnated and our city streets have become an extension of the 57 & 60 freeways. Who made these terrible decisions? Shame on them. 119. We need more open space, land, and trails. If the golf course becomes obsolete, I would NOT want housing or shopping there - it should be come a park. Our streets and freeways are already crowded enough. 120. We need more stuff to do like a movie theater 121. We need our own facilities to solidify our existence as an independent and successful city, and the first step is our own police station. 64 1.1 Packet Pg. 433 1.1 Diamond Bar General Plan Update 122. We need to make use of the land we already have and limit overcrowding and congestion in the lots that are already being used. 123. We need to update the exteriors of the srip mall across from lorbeer middle school 124. why are all small businesses in diamond bar closed on mondays 125. Would like to see a Gelson's, Whole Foods, Trader Joe's come to the area. As well as upscale restaurants and a variety of other eateries --- Vitality Bowl in Brea, Chop Stop in Rancho Cucamonga, etc to name a few. For more upscale restaurants --- Mastro's, Roy's, Fig and Olive in Newport Beach, Benihana, Javier's, etc. Casual dinning --- Urban Plates, Mendocino Farms, P. F. Changs, Pieology, Cheescake Factory, Panda Express, Ruby's Diner, Tender Greens to name a few. Diamond Bar needs a bigger and better variety than what we have. 126. Would love a downtown area 127. would love a trader joes 16. Thinking into the future, what is the one thing you would do to most improve Diamond Bar over the next 20 years? (360 Responses Total) 1. 1 city. No more north vs. South and 2 school districts 2. 1) Traffic of DB Blvd. 2) DBHS really should be more proactive about making sure the kids who attend that school really do live in DB. It is FRUSTRATING to live 5 min (driving) from the school but need to take the long route to drop off my son be EVERYONE from Rowland Heights attend DB schools. Specifically, cannot go straight down Pathfinder to DBHS be all the people from Rowland Hts are also dropping their kids off in DB schools. We have to take the long route by traveling pass the fire station & then down Brea Canyon Cut Off and thru residential and then under the fivy and back up the street to DBHS just to get to the school each morning. It shouldn't be like that. 3. 1. improve/clean streets with added safety utilities such as installing CCTV's along busy streets and school vicinities that police can monitor through central stations 2. ensure homeowners keep their property with curbside appeal. we see that some homes show dilapidated painting, trashy appeal lowers property values & invites "under -desirability" 4. 1. school districts 2. the economy 3. law and order 5. A City Internet Provider Utility would help save residents money and bring in new businesses. 6. A different road toward Chino Hills. 7. A downtown area and more hiking trails. 8. A family shopping center with sprouts or similar 9. A more culturally diverse city. 10. A nice mall and security 11. A parallel route to Diamond Bar Blvd through the country or right behind it. Do not destroy every hillside. 12. A place with more activities and places you can walk to 13. activities and hang outs 65 Packet Pg. 434 Survey Report 14. Add a downtown area 15. Add a Downtown Diamond Bar or Main Street kind of place. We need night life that's accessible for FAMILIES! I don't want a bar. I took my kids bowling over the summer at Oak Lanes Bowling, and I could smell all the smokers at the nextdoor bar. I could feel those bar customers sitting in the patio staring at me as I walked with my kids. What is this? Come on ... Diamond Bar is more than a run down, commuter city ... yet whatever Diamond Bar is, is not reflected in the city landscapes/businesses/restaurants. Well ... unless we're only boring restaurants and run down tutoring centers, with the usually closed up frozen yogurt or donut shops, or the usually empty Enchilada restaurant. My family wants excitement in Diamond Bar. A movie theatre! A splash pad at one of the parks. A promenade area. Liven up our lives in Diamond Bar. 16. Add cheaper, affordable housing for people. 17. Add entertainment, restaurants, night life. IMPROVE TRAFFIC 18. Add more diverse choices for retail, food, and business. Too much emphasis now on Asian demographic. 19. Add more fun to attract lots of people. 20. Add more hiking trails and have more community opportunities to volunteer. 21. Add more law enforcement 22. Add more night life, improve traffic and more restaruants 23. Add shopping, restaurants and markets 24. Add speed bumps/humps or other traffic calming tactics near Pantera park. 25. Adding entertainment/shopping town center to increase local tax base for future city growth 26. affordable housing 27. Affordable housing shops open space parks 28. Again, traffic. Also, stop building more housing. We are losing the rural feeling that drew us to DB in the first place. 29. All advertising done in english, then a foriegn language. 30. Alleviate traffic in south diamond bar over to Chino Hills, without destroying the habitat and open spaces. Roads with wildlife corridors are great, no more businesses or homes. If we do build something, I'd love to see a board walk at Lake Arnold with shops and dinning and vista each way. 31. Amusement parks 32. Attract families 33. attract more office users in the Copley area to generate tax revenue and people to our business' and restaurants 34. Attract more specialty shops, restaurants, at least a small shopping place (not a Shoppes per se), make it easy for people to get about - increase bus stops, improve walking paths, make it safer for kids to walk/bike to school and back, a theater or playhouse would be good too. 35. Attract popular stores/restaurants to the area to revitalize the area so that we don't have to travel to chino hills, brea, Rowland heights to shop, eat, hang out in that area 36. bar 37. Be more of a cultural hub. Provide something our neighboring cities cannot 66 1.1 Packet Pg. 435 1.1 Diamond Bar General Plan Update 38. Beautify and clean up certain areas of our city, especially as I have mentioned, housing area north of the 57/60 freeways and east of Grand avenue. Recently presumably a developer pushed dirt higher and now blocking view of the sunsets then suddenly stopped and left it barren with nothing but tumbleweeds now growing and a lot of dust a la TransAmerica Corporation. 39. Because of the many different cultures living next to one another, I feel there is a need to have more different culture activities to bring them together. 40. Beside the traffic issue, the most important thing would be to improve electricity and Internet service. I work from home to take care of kids and rely on both, so I have a bias. I've had to deal with multiple blackouts or short power outages to the point I'm looking to invest in solar panels plus batteries to limit the impact. I currently have FIOS, which switched from Verizon to Frontier. The service is decent, but the cost is a concern, especially since there's always a push to buy additional services. If there's a way to get something like Google Fiber for Diamond Bar, it would really benefit people with my circumstances. 41. Better control of traffic buildup on Pathfinder From Brea Cyn Cutooff to Diamond Bar Blvd 42. Better markets 43. Better streetlight time 44. Better thoroughfare than just Diamond Bar Blvd 45. Bring business so that we can shop/eat locally rather than go to neighboring cities. 46. Bring in additional major retail stores 47. Bring in and support quality local businesses. 48. Bring in chain stores and food places with room for local business as well. Relocate City Hall and the Library for easy resident and business access. 49. Bring in major restaurant and retail chains. We need something like The Shoppes at Chino Hills. I hate having to constantly leave Diamond Bar to spend my shopping dollars. 50. Bring in restaurants that offer a wider variety of foods. 51. Build new shopping centers 52. business, create local jobs 53. Businesses 54. bypass road to get Chino Hills drivers off of Diamond Bar BLVD. Fix 60 x 57 FWY bottleneck 55. City beautification 56. City needs a general theme for the construction of new and rehab of old properties. Also traffic is miserable. Diamond Bar has become a pass through for people going into Chino Hills when the freeway is bogged down. Something has to be done to divert traffic off the city streets. 57. Clean trash and support local businesses 58. Clean up certain areas and have more family activities. 59. Clear Congestion More strict regulation on properties maintenance 60. Common areas 61. Community Center with pool; fitness classes and family activities; learning center 62. Community downtown area 67 Packet Pg. 436 Survey Report 63. Congestion on diamond bar Blvd & on 57fwy an 60 f vy meet. 64. Conserve our open space for perpetuity. 65. Continual monitoring and improvement of an ongoing city improvement program which reflect community pride. 66. Continue school updates with technology. We have an amazing school district, with dedicated teachers. More senior housing and restaurants are needed. Easing freeway and major road congestion is a must. Diamond Bar is a great community but if we add lots of housing and big box stores, it will just become an overcrowded suburb like many cities close to LA. Diamond Bar offers a mix of green, undeveloped land and plenty of businesses to suit its residents. 67. continue to make more schools. top notch to our city is desirable 68. Continue to offer facilities for club activities and outside recreation for our youth and adults. 69. create a central hub for community events. 70. Create a Diamond Bar/Walnut city police department. This will improve response times to calls of service, give Diamond Bar/Walnut the ability to investigate crimes in-house (which will lead to crimes being solved quicker), help the cities combat the more prominent issues that occur such as burglary, theft, homicide, and drug enforcement with less reliance on other agencies (which will also drastically lower these issues and save both cities money), and strengthen community policing with the help of School Resource Officers/Community Impact Teams/Gang Enforcement/etc, something that Diamond Bar and Walnut are currently lacking in. Cities with their own police departments usually see a drop in crimes and much more effective style of policing. 71. Create a town center. Convert a park into an agricultural learning center. 72. Create an entertainment area where families can go together - along with developing centers for instance the Kmart center needs a face lift. The Acapulce Center also needs updating with new shops. The area off of Grande is beautiful and open and should not be touched 73. Create more jobs 74. create more opportunities for the community to connect - neighbors united create a more stronger community. events, places that bring people together are important 75. Create more preserved open space, eliminate freeway bypass traffic, curb all new housing, reduce cities population 76. Create more shopping centers 77. Create our own downtown area and don't over develop or add more housing. 78. Create/attending an inclusive community atmosphere by planning/creating fun cross- cultural/ethnic community activities (involving food, music, entertainment and information) as a way to recognize and embrace our diverse population within our city. 79. Creating shopping entertainment in the city - currently have to go to surrounding cities for this (walnut, chino, industry). Provide resources/activities for families/kids. 80. Currently, the city unlike Walnut City, is not connected. People from the local schools cannot walk to the library to study, go to the senior center, city hall, or go shopping without a car. These should be connected to make the city pedestrian friendly. It is good for the elderly and kids. City also needs more stores besides restaurants; for example we need large 68 1.1 Packet Pg. 437 1.1 Diamond Bar General Plan Update retail stores, business, and high end specialty stores. (high quality clothing, sports, household goods) 81. DB needs its own school district 82. Decrease/eliminate traffic congestion, increase safety of Diamond Bar, bring in small businesses (not big chain stores), and improve/maintain the greenery in Diamond Bar. 83. Develop trail, multiuser parks and natural spaces 84. Developing vacant lots 85. Diversity (2) 86. Diversity in our shopping/eating/entertainment choices. 87. Diversity. In restaurants 88. Don't let us continue to be a drive thru city. 89. Downtown with family activities 90. Ease the traffic congestion both on city streets and the freeways that go through Diamond Bar. 91. Eating choices, places to go for young people 92. Eliminate night parking on our crowded streets. Decide if we are a bedroom community or a business community. It appears we are trying to do both. We have some tired looking shopping areas, poorly kept condominiums, and a very nice tree lined main street. Hold businesses and home owners to a higher standard to meet the needs of a growing community. 93. encourage everyone to go green 94. Enforce traffic laws. Give us more choices for eating & shopping to keep our money in Diamond Bar. 95. Enhance our outdoor recreation opportunities such as public accessibility to open spaces, lit playing fields, and more bike friendly roads. 96. Entertainment 97. Entertainment and dining options. 98. Environmental sustainability 99. Evergreen school need to use the red curb for drop off like they used to 100. expand entertainment area for residents 101. Find a way to clean-up land between major streets and visible areas behind homes maintained. 102. Fix congestion on our streets! Too many people use DB streets as alternative to feeeway traffic & do away with golf courses 103. Fix the 57/60 freeway interchange. 104. Fix the 57-60 congestion it's an accident trap and will only get worst unless addressed 105. Fix the dangerous intersection of 57 & 60 - too many daily accidents 106. Fix the traffic problems. Stop any more construction of homes. 107. Focus on a safe and well -kept small community. 108. Focus on business development 69 Packet Pg. 438 Survey Report 109. Focus on the health and safety of its residents. Preserve open spaces so that future generations can enjoy. 110. Get senior center 111. go green 112. greening the environment 113. Have a local place locals and others will come together. A place where diamond bar will be known for great hang out place, safe and tight community. 114. Have a welcoming town center 115. Have more stores and food places instead of little family owned shops 116. Help small business owners that operate in our city. 117. Housing (2) 118. Housing and business 119. Housing renovation 120. I believe that diamond bar could improve if we create more housing 121. I like the multicultural aspect of Diamond Bar but am concerned when there are many businesses that don't have signs and or menus in English. 122. I think we should expand our land more and have more activities such as movies, shopping, etc. I think we should also have more public transportation. 123. I was at the community workshop and was disturbed but not surprised to see that the median age of the participants was about 55. This does not take into account the needs of the young families that use the youth sports fields in DB. I believe they would have a great input on the shortage of sports fields in the city. They however are the busiest people in the city, taking kids to practices, needing care or working to make sure the kids do homework. Suggestion: Contact the youth sports programs in the city to get their input from their leaders. 124. I will be leaving because there is nothing to do here 125. I would add more parks to make this place more entertaining. 126. I would find land to build and indoor sports complex. There is a definite need for one for youth and adults the same but we have to either use the schools or go to surrounding areas community centers. 127. I would like to see a huge development so we don't have to travel to chino hills, industry, west Covina or Brea. We need to keep tax $ in DB. 128. I would like to see that DB becomes a city where people come to because we have those attractive businesses and the nicer parks. Instead of removing the golf course, how about cleaning it up so more people come to DB to use it? I love having a golf course in DB. It makes the city more attractive from the freeway. 129. I would make more houses 130. I would put more small businesses and restaurants in Diamond Bar. 131. If there is no entertainment for young adults, this city will be nothing but children and old people. 132. Improve community interaction and engagement by establishing a city center, where housing, public space, and entertainment meet. Get rid of the narrative that Diamond Bar is a bedroom community. 70 1.1 Packet Pg. 439 1.1 Diamond Bar General Plan Update 133. Improve infrastructure, neighborhood beautification 134. Improve parking at local businesses --fewer stores but with adequate parking, which doesn't exist now. 135. Improve shopping and restaurant choices. 136. Improve the North end of Diamond Bar. Also increase the popularity of Diamond Ranch HS and keep it for Diamond Bar Residents only. 137. Improve traffic (2) 138. Improve traffic and increase parks 139. Improve traffic flow 140. Improve traffic flow problems along Grand and Diamond Bar Blvds. 141. improvement in our sidewalks and traffic in in the afternoon for a bedroom community 142. Improvement of traffic especially in school zones and specifically in the school parking lots 143. Include new stores and things to do 144. Incorporate shopping, social areas so Diamond Bar residents spend their money in the city as opposed to spending and socializing in other local cities, such as the Chino Hills Shoppes and the Claremont Village. 145. Increase district limit 146. Increase the tax base through providing more upscale shopping and eatery experiences for residents while maintaining open space by redeveloping exisitng shopping centers and the golf course. 147. Indoor basketball court, public swimming pool, letter from Santa, upgraded looking shopping centers, American breakfast restaurant and large park with a train, small petting zoo and water fountain with low admission fee and plenty of parking. Think in terms of birthday parties. Trees needed for pinatas, picnic benches, bike trails (stroller friendly), outlets for lighting, bounce house space. Family time is important. 148. Infrastructure 149. introduce creativity 150. It comes down to retail and entertainment 151. It is the big market company 152. It's nice the way it is. Just maintain roads, parks even brighter lamp posts, maybe. PARK patrols coz too many unleashed dogs at Pantera. Utilize Bark PARK for something else coz the dogs share the walking path at Panetta anyway. Too many dog owners not picking up dog poop. 153. jobs 154. Just keep it quiet and not busy. Shopping at nearby Chino Hills, Rowland Heights, west covina and Industry is more than enough. 155. Just up keep of roads and parks 156. Just what was already mentioned; improved streets and freeways, upgrade old shopping centers and better parks and entertainment centers. 157. Keep growing, we replaced the grass in the middle of the street with draught tolerant srubs and trees, we must do the rest for all of diamond bar. Making a name out of its self for more than just the intersections between all freeways 71 Packet Pg. 440 Survey Report 158. Keep the city safe for the kids, with lots of clean parks and don't destroy nature, once it's gone it's gone forever. Also do something about the vagrants, that's something we didn't use to see 159. Keep the open spaces 160. Keep the small town feel keep it quiet and quaint 161. keep the small town feel with plenty of city activity and common places for people to meet 162. Kmart lot improved 163. Land preservation More large commercial stores in existing areas (not unbuilt land) 164. Leave the open land and make a regional park were Tres Harmonos is. Renovate the golf course and use it as a real country club. 165. Less Asian only store fronts. All signs should be English. 166. Less congestion 167. Less home building 168. Less pollution 169. Limit housing, leave the open spaces alone. 170. Lobby hard to widen the freeways so the traffic on our streets could be reduced. 171. Longer and safer bike routes 172. Magnet downtown area. 173. Mainstream dining and entertainment 174. Maintain and keeping the city clean 175. Maintain quiet life style, fix traffic. 176. Maintain school of choice program. use open land btw db and ch only for general parks, hiking, etc. 177. maintaining nature and wildlife. 178. Make a town center 179. Make DB be a place where people in surrounding cities would come to shop, eat, and enjoy all the entertainment it has to offer 180. Make Diamond Bar less boring. 181. Make it have a small town feel 182. Make it more attractive to live and do business than neighbor city, i.e. Walnut and Chino Hills. 183. Make it more exciting to live in. We are constantly having to go to chino hills, Industry and brea for shopping and entertainment. Would love to see a Trader Joe's. 184. Make it more like brea or chino hills 185. Make it more like brea. Attract multiple cultures, not just asians. 186. Make it more safe 187. Make it safe and naturally beautiful to walk and hike in streets by planting more trees, flowers, grass, etc. 188. Make it safer 189. Make the housing affordable to everyone, and not let a certain demographic group dictate what kind of restaurants and stores get placed 72 1.1 Packet Pg. 441 1.1 Diamond Bar General Plan Update 190. Making it cleaner 191. Making it drought friendly while still green would be ideal. I feel safe here so keeping that feeling is also important 192. Making more athletic parks and facilities 193. Minimize commuter thru traffic. 194. Minimize the traffic on major streets. Improve the views by trimming over grown trees. 195. Mitigate the traffic congestion on Diamond Bar blvd. 196.

Not letting commuters cut through our town to avoid the freeway mess. 230. Nightlife 231. No horns from trains on tracks behine Lycoming St like Walnut did on Valley Blvd 232. No more homes! 233. Not all housing are equal. To make the not so good looking houses nicer, city will need to find ways to assist homeowners to improve them. With better looking houses, there will be less foreclosure as these homes will sell faster and easier. 234. Only allow small business, and make it very friendly for them. Redesign, relandscape, a greener city, plant more drought tolerant trees. Mulch, remove grassy areas. Plant butterfly gardens, create wildlife habitats, create a community park/farm which sells and grows local, seasonal vegetables and fruits. 235. Outside mall 236.

Please fix the 7:40 AM traffic on Grand and DB Blvd 247. Preserve open spaces and heavily restrict or curtail completely new construction of all types of areas that do not have existing buildings/structures. Keep Diamond Bar green, hilly, open and beautiful. 248. Preserve the open space by focusing development projects on renovating existing commercial properties. The old K -Mart Center could be a great space for a Whole Foods Market that could include public art and areas to gather with neighbors and friends. 249. Preserve/restore natural resources, ecosystem services. The potential reckless development of Tres Hermanos Ranch, punctuates the seriousness of making true conservation of DB natural resources a priority. Presently, there is no program to specifically monitor or support ecosystem services - which, once gone are gone forever. Carbon sequestration of mature coast live oaks is greater than any 24 " mitigation tree. DB planning & mitigation policy is outdated. Speculation development threatens the health and wellbeing of our community as it ignores CEQA, has converted historic landscapes, creeks, glutted hill ridge lines with mansions (mostly vacant and/or are Airbnb rentals). Lax planning processes "spot zone" parcels, allowing for denser/more congested neighborhoods, contribute to the 74 1.1 Packet Pg. 443 Diamond Bar General Plan Update loss of native landscapes, view sheds, hillsides. Overly large home remodels cause unregulated multi -family housing, ruining neighborhood integrity. DB planning must change and stop piecemealing. CEQA laws must be adhered to and not softened, diverted or categorically exempt for properties of sensitive environmental areas. 250. Preserving and/or increasing open spaces. 251. Preserving the environment 252. Protect the wildlife. 253. Protect Tres Hermanos before it's too late. Make it into a state park with trails and room for wildlife, similar to Pantera Park. Yes, we need more housing in the region, but forces outside of Diamond Bar's jurisdiction make it impossible for DB to create the necessary transportation infrastructure to support more housing in our city. Larger roads in DB will only increase commuter traffic through our city. Given continual property value increases in the region, pressure on our area freeways will increase at a rate beyond anyone's ability to keep up with the demand. That will keep us forever as a crossroads with commuters moving through our city. We need to accept that we are powerless to stop this and instead keep Tres Hermanos as open space, any sort of development will only make traffic even worse than it already is. 254. Provide common essentials. 255. Provide facilities to promote family time, safe activities for young ones and seniors. 256. Public transit- our bus options are limited to once/ hour on DB Blvd. It takes my son 3 hours to get to Mt.Sac and 3 buses. We need to improve this transit connection between Chino Hills and Walnut via Grand 257. public transportation 258. Put more diverse restaurants and add entertainment. It is frustrating have to drive to neighboring cities such as brea and chino hills all the time. There is no nightlife here at all. 259. Redo Diamond bar Bl/Grand AC to be a central down town type area with more restaurants less banks 260. Reduce driving. 261. Reduce freeway traffic noise 262. Rehabilitate the older neighborhoods -both the residential and retail. 263. Remove all of the strip malls- they are unattractive and make our city look run down. At DB blvd and quail summit, DB blvd and golden springs, DB blvd and temple 264. Renovate all the shopping centers, markets, and shops. Add more variety in restaurants and shops. 265. Resolve traffic issues. Consider outside of the box thinking like closing Grand Ave access to Chino Hills. DBar's traffic issues come as a large result of increasing population in Chino Hills. Our neighboring city continues to build new homes and Grand Ave is the outlet for them to avoid the 60 freeway. 266. restaurants 267. Restaurants, bar and grills 268. Retail and restaurants, not Asian food... 269. routes to diamond bar, including fwys 270. Running for city council. 1.1 75 Packet Pg. 444 Survey Report 271. safety 272. Same as 14 273. School district cannot let other city student chime in. Otherwise, no one will want to buy db home anymore, then our house value will go down, then resident wont be proud to live here. 274. School district zoning 275. School traffic areas are VERY unsafe and distressful for residents. 276. Schools (2) 277. See previous comments rebuild 278. Semi upside stores and restaurants 279. Shopping 280. Shopping and entertainment center that is super pedestrian friendly would be great 281. shopping center 282. Shops and quality of life improvements. 283.

Stand up to developers and preserve open spaces like the hills between DB & CHills. 290. Stop all development and return some of our vacant lots back into natural habitat or park and wilderness sites. 291. Stop building homes. DO NOT develop Tres Hermanos. Keep our green space/hills. 292. stop building houses and developing open spaces. Diamond Bar is a city founded on country living and that is rapidly being taken away by housing and traffic 293. Stop building track homes and condos. They take away from what makes diamond bar a special place to live 294. Stores 295. Strive to keep the country living atmosphere 296. Support and tell my friends ,neighbors and business associates about my ideas. 297. support local businesses 298. Support local businesses owners 299. Sync the lights. Improve the intersection on Golden Springs and Brea Canyon Rd. Keep existing business and bring in more family friendly activities. Bring more American based shopping to fill the old KMART store. 300. telephone polls removed i.e.: underground utilities 301. The most important thing for the city to do is to preserve our green space. Keep Tres Hermanos undeveloped. 302. The population is aging - need to focus on taking care of seniors 76 1.1 Packet Pg. 445 1.1 Diamond Bar General Plan Update 303. The traffic situation. It's the most salient issue for our city. Also, having an electric vehicle infrastructure will be a great thing. We have the AQMD in our city limits, why are we not leaders in this regard? Charging stations, etc. 304. There should be more activities and restaurants that families and friends can spend time and have fun at. 305. Throw away trash in the streets 306. Tonner Canyon opened to Chino Hills to reduce our traffic. Beautify the city with revenue from increased ticketing of bad drivers. 307. Traffic (11) 308. Traffic (faster); bicycles; intelligent city; technology in favor social; better quality of air 309. Traffic and entertainment 310. Traffic conditions need major improvement on Diamond Bar Blvd. 311.

Traffic light timing or sensors 315. TRAFFIC MITIGATION 316. Traffic reduction 317. Traffic signals need to be smart computerized. Traffic signs should be clear. Right turns on green light need to be banned. 318. Traffic, restaurants/shopping and parks 319. traffic/60/57 320. Try to keep residential revenue within Diamond Bar so people aren't shopping and eating in neighboring cities 321. Unity. Diamond Bar should be seen as 1 city, so get rid of the "North" and "South" terms and have only 1 Diamond Bar school district. 322. Update strip malls 323. Upgrade 324. Upgrade north dB area 325.
