PUBLIC HEARING(S): None None Farago, Shah, VC/Torng, Chair/Nelson None Lin None 7.1 Development Review No. PL2012-100— Under the authority of Diamond Bar Municipal Code Section 22.48, the applicant and property owner Ahdy Ayad, requested Development Review approval to construct a new 4,033 square foot single family residence on a 0.21 gross acre (9,320 square foot) lot. The MAY 28, 2013 PAGE 2 PLANNING COMMISSION subject property is zoned Low Density Residential (RL) with a consistent underlying General Plan land use designation of Low Density Residential. PROJECT ADDRESS: PROPERTY OWNER: APPLICANT: 23885 Minnequa Drive Diamond Bar, CA 91765 Ahdy Ayad 12162 Black Stone Drive Rancho Cucamonga, CA 91739 AP/Tobon presented staff's report and recommended Planning Commission approval of Development Review No. PL2012-100, based on the Findings of Fact, and subject to the conditions of approval as listed within the resolution. VC/Torng referred to Attachment 2, a letter received from Mr. and Mrs. Thomas Tobin, dated May 20, 2013. He said the neighbor's letter referred to Glendora's Code which calls for a 33 percent roof per 10,000 square feet of land and asked if Diamond Bar had such a code. AP/Tobon responded that the City's Development Standards state that within this zone there is a maximum of coverage of 40 percent footprint and the proposed project is 24.4 percent coverage. Chair/Nelson asked if it was a percentage of the footprint of the house or all hardscape and AP/Tobon responded that it is anything and everything with a roof so it includes the footprint of the house, patio covers and any other accessory structures. Chair/Nelson opened the public hearing. Yasmine Ahmir, 1105 North Golden Springs Drive, said the issue was that due to a landslide, the house became inhabitable and was demolished in 2012. His engineer submitted drawings according to the requirements and the City's Code which the City approved. This project does not change the character of the street of Minnequa Drive and there should not be any problem with traffic nor should it have a negative impact on future sales. This project will add beauty to the homes on Minnequa. He feels that the person who cited the Glendora code (Attachment 2) did not realize that Glendora is an old City and Diamond Bar is a fairly young City. Mr. Ahmir submitted to Chair/Nelson a letter in support of the project signed by the neighbors surrounding the project. Chair/Nelson asked for CDD/Gubman's recommendation on how the letter should be received and CDD/Gubman stated his recommendation was that the Chair pass the letter to the Commissioners and that the letter then be entered into the record. Chair/Nelson offered the following summary: The letter is essentially in support of the project with a number of residents within the same MAY 28, 2013 PAGE 3 PLANNING COMMISSION street and/or less than one mile radius of the property stating that the project will not change the character of the houses located in the area. The height will be the same as that of the previous house and the elevation conforms to the City's regulations and that the project will not have a negative impact on the value of homes in the area. The letter speaks against the nature of the Glendora restrictions indicating that those restrictions basically do not apply to this project; that from an engineering and architectural standpoint there are quality individuals involved; there is a certificate of compliance for the plans and development for the Ahdy Ayad single family home issued by the engineers and the letter contains a number of signatures. In essence, this is a letter of statement from neighbors who say they have no problem with the project under any means whatsoever. Chair/Nelson entered the letter into the record and continued with the public hearing. Lianbin Hou, 23900 Minnequa Drive, across the street from the proposed project, said that he was against the project because he believed the size of the house would be double that of the house that previously existed and that it was not in keeping with the houses in the area. Second, the house is a two story house and that the house was one story and the proposed project will affect the houses on the west side. Third, the house is big and has a two car garage so there will be lots of people living there and where will they park and probably will park on the street. ' Ms. Yung, 23891 Minnequa Drive, next to the proposed project, said her house is a one-story house and a two story house next to her is too big and will block the light from her house. Also, there is only a two -car garage for such a big house. When the applicant finishes the house he may sell the house and there will be a big family living in the house. With only a two car garage cars will be parked on the street so it will create more traffic in her neighborhood. Emad Nabih, 8715 Pradero Court, Rancho Cucamonga, contractor, stated that when he submitted plans to build this house, they were submitted according to location, specifications and building codes. In addition, all setbacks and soil stability has been done to code. The City has reviewed and approved those plans. The recommendation for the slope came from GMU, the geotechnical engineer responsible for the landslide repair. The foundation was designed according to the specifications with a high factor of safety. With respect to the two car garage and the family that lives in the house, the area will not be impacted with vehicles because a two -car garage is sufficient for this size house which accommodates a husband, wife and one child. There are already some cars parked overnight on the street and there are no restrictions for parked cars because they do not block the traffic. The applicant made every attempt to match the area in accordance with Building and Safety recommendations. There is no attempt to do anything that is outstanding or out of the norm for the area. In addition, this house will increase the value of MAY 28, 2013 PAGE 4 PLANNING COMMISSION homes in the neighborhood because it is brand new and the next door neighbor will benefit from this project that also adds to the City and the community. Ms. Yung returned to say that the slide mitigation was guaranteed for only 10 years and after 10 years it will happen again and they will not warranty it again. Also he said it is a beautiful house and she agrees. But the surrounding houses are small and suddenly when there is a big house next to a small house it does not add to the value of her home, it detracts from that value. Raf Madrid, 17840 Newbrook, Cerritos, Certified Inspector for Los Angeles County, said he was involved with looking at the house and the slope failure. In his opinion, this area is a very good area. He lives in a two story house and no other houses on his street are two story. His house was built in 1975 as the rules and regulations allowed and there was no restriction from the point of view of Building and Safety. The regulation for the City also allows for distance between the houses for fire safety and the proposed house meet those codes. The City of Diamond Bar has a very highly qualified staff and they know what they are doing. The engineer who submitted the plans knows the codes for single family homes and the rules were very carefully applied for this single family home for many reasons including insurance. Both sides of this home are safe for purposes of lighting. From a fire safety standpoint, the back of the house is an open area. The front line of the house matches all of the other houses in the street. Who will be living in this house is not the concern of anyone in this district because it could be one person with two cars or five people with only two cars. These plans were submitted to the City by a professional structural engineer under California Building Codes. The architect is certified and builds in accordance with California Building Codes. The City sends the plans to two consulting engineers to carefully study the plans, thus the recommended modifications which were done. After that the City made three revisions to the plans — plans do not pass through this City that easily and the Planning Division of this City is responsible about what will be built in their community. Anyone who objects to this house is dealing from an emotional standpoint and this house is being built to code. With no one else present who wished to speak, on this item, Chair/Nelson closed the public hearing. C/Lin asked what the footprint of the house is and CDD/Gubman responded that the square footage of the lot is 9,320 and the lot coverage as stated in staff's report is 24.4 percent (the footprint of the house) or about 3,000 square feet which is the area of the first floor, garage, covered patio, covered entrance which is 2,274 square feet. The 2,992 square feet does not include the garage. With the inclusion of the garage and balconies the square footage totals 3,723 square feet which is the gross floor area. C/Lin said that typically, garages and balconies are typically not considered "living space." MAY 28, 2013 PAGE 5 PLANNING COMMISSION CDD/Gubman said that C/Lin was correct and directed him to pages 3 and 4 of staff's report which contain four bullet points breaking down the square footage that comprises the structure. C/Lin said that the setbacks are to code and nothing that is proposed to be built is in contrast or violates the City's Subdivision Code and CDD/Gubman confirmed that C/Lin was correct. C/Lin said that in terms of how many members live in the house is not included in the criteria for approving or denying the project and neither does the blocking of light from the neighbor's property and CDD/Gubman confirmed that C/Lin was correct. CDD/Gubman said that when staff reviews projects, every effort is made to take into account compatibility with neighboring structures in terms of privacy, ensuring that bedroom windows do not face each other, etc. He showed the photo of the building that was demolished which was a two-story residence. The neighboring one-story house is shown on the right and that house is actually upslope from the project site so that even though it is one- story, the subject property is down slope and its pad is actually a few feet lower than the one-story house so that the proposed structure is not looming over the neighboring property and there will be no impacts in terms of creating shadows onto the neighboring property. C/Lin asked if the City had the landslide repaired and CDD/Gubman responded that the City had to review the structural engineering plan and the landslide had to be repaired to a minimum safety factor which is a technical term that gets into its geotechnical stability. The slope repair has been engineered so that it is not going to fail. This is a safe building pad and it has improved the safety for the surrounding properties as well. The slope repair went through an extensive engineering effort and has been vetted through the City's geotechnical consultants to ensure that it meets or exceeds the minimum safety factors required. C/Lin said it has a 10 year warranty and who paid for the repair and who is responsible for the failure of the construction. CDD/Gubman explained that the engineer of record is ultimately responsible and has liability insurance that covers the work. The landslide occurred on private property, not on public property. C/Farago asked if the house on the down slope to the west of the project site was a two story structure and CDD/Gubman responded yes as seen on the upper left of the slide. C/Farago asked the square footage of the project that was demolished and CDD/Gubman responded that the living area was 2093 square feet which is a net increase in square footage between the former and new structure of about 900 square feet. C/Shah said that it appears that according to the site drawing the square footage meets all of the requirements for the City. The slope and slide is a geotechnical issue and once it was fixed it was warranted for 10 years which surprised him. MAY 28, 2013 PAGE 6 PLANNING COMMISSION CDD/Gubman stated that any development project that goes through the Planning Commission for review, the Commission is reviewing it for use of the land and for the appropriateness of the way in which the building was designed. The Planning Commission's approval is subject to several conditions that must be complied with before the City issues permits. The Planning Commission is not looking at the structural plans for the house because that is something this approval is subject to — 'subject to going through the Building and Safety Division for verification that the structural plans comply with the building codes. There is the same requirement for the earthwork and for all of the grading that would be involved. Those structural safety building code requirements are mandated to go through the technical staff for verification that they meet the safety criteria. The Commission's approval, in this case and as always, is subject to the City's technical staff's ensuring that no permits are issued and no final inspections are signed off until staff has verified that all construction and all designs have been done in compliance with the relevant safety codes for the State of California. VC/Torng asked for a clarification of the balcony square footage on Page 1 of staff's report. C/Farago said that according to the plans, the square footage of the demolished house first floor was 1,280 and the first floor of the new building is only 1,465 which is a difference of less than 200 square feet. The second floor is 1,527 and the demolished building was 813 so the increase in the square footage can be found in the second floor. CDD/Gubman said that C/Farago made a good point. Chair/Nelson said that as long as he has served on the Planning Commission it has never rejected the idea of having families want to increase the size of their homes or move out of Diamond Bar. This is a very family friendly City and supports approval. He also believes that the rule of real estate does apply that if you want a good investment in real estate you buy the lesser valued home on the block and move up from there. C/Lin moved, C/Shah seconded, to approve Development Review No. PL2012- 100, based on the Findings of Fact, and subject to the conditions of approval as listed within the resolution. Motion carried by the following Roll Call vote: AYES: COMMISSIONERS: Farago, Lin, Shah, VC/Torng, Chair/Nelson NOES: COMMISSIONERS: None ABSENT: COMMISSIONERS: None RECESS: Chair/Nelson recessed the Planning Commission at 7:40 p.m MAY 28, 2013 PAGE 7 PLANNING COMMISSION RECONVENE: Chair/Nelson reconvened the Planning Commission at 7:50 p.m. 7.2 Development Review No. PL2013-104 — Under the authority of Diamond Bar Municipal Code Section 22.48, the property owner, Samson Family Trust, and applicant Federico P. Samson, requested Development Review approval to demolish an existing house and construct a new 7,401 square foot single family residence on a 0.84 gross acre (36,590 square foot) lot. The subject property is zoned Rural Residential (RR) with a consistent underlying General Plan land use designation of Rural Residential.

Samson 2442 Alamo Heights Drive Diamond Bar, CA 91765 CDD/Gubman presented staff's report and recommended Planning Commission approval of Development Review No. PL2013-104 based on the Findings of Fact, and subject to the conditions of approval as listed within the resolution. VC/Torng liked the plan and staff's detailed report Chair/Nelson opened the public hearing. Federico Samson, property owner, asked the Commission to please approve the project which he feels will improve and upgrade the neighborhood. The current house is outdated. With no one else present who wished to speak on this item, Chair/Nelson closed the public hearing. C/Farago moved, VC/Torng seconded, to approve Development Review No. PL2013-104 based on the Findings of Fact, and subject to the conditions of approval as listed within the resolution. The motion was carried by the following Roll Call vote: MAY 28, 2013 PAGE 8 PLANNING COMMISSION AYES: COMMISSIONERS: Farago, Lin, Shah, VC/Torng, Chair/Nelson NOES: COMMISSIONERS: None ABSENT: COMMISSIONERS: None 8. PLANNING COMMISSIONER COMMENTS/INFORMATIONAL ITEMS: None C/Lin asked about the status of the potential Ralph's project. CDD/Gubman responded that the Walmart Neighborhood Market will open in that space when corporate elects to tell the City when construction will take place and when the store will be open for business. There is a larger rollout plan for several locations but staff is not privy to that information at this time. C/Lin asked if the plan would be submitted to the Planning Commission for approval and CDD/Gubman responded no, only if the exterior of the building were to be modified. If this project involves only an interior remodel with new signage it would not come to the Planning Commission. C/Lin asked if traffic and parking would be a problem and CDD/Gubman responded that if the square footage does not change and the property is going from a market to a market, it would be exempt from that type of review. 9. STAFF COMMENTS/INFORMATIONAL ITEMS: 9.1 Public Hearinq dates for future Proiects. CDD/Gubman stated that the June 11 Planning Commission will go dark since there are no scheduled agenda items and the next Commission meeting will be June 25. There are currently two items on the agenda: 1) addition to a single family residence and 2) a new office building at the corner of Brea Canyon Road and Washington Street. CDD/Gubman further stated that staff released the Environmental Impact Report (EIR) for a zone change for a portion of Tres Hermanos that lies directly south of Diamond Ranch High School. When the City adopted the current Housing Element it was obligated by the state to establish zoning in the City at a sufficient density to accommodate 490 affordable housing units which is simply defined as creating zoning that allows a density of 30 units per acre. It is not that the City is going to be subsidizing or providing any financial backing for a project, it is simply obligated to provide a zoning designation with sufficient acreage to accommodate that number of units at the given density. Staff anticipates coming to the Planning Commission on August 13 for the first hearing on the proposed zone change. The EIR has been released for a 45 - day public review period. If the Commissioners have any questions on the document feel free to contact him or SP/Lee. If the Commission would like to have a study session as it did when the Site D EIR was released, that can be scheduled for the June 25 meeting. MAY 28, 2013 PAGE 9 PLANNING COMMISSION Chair/Nelson asked that any Commissioner wishing to schedule a study session should contact CDD/Gubman for scheduling. VC/Torng said he would like to have a study session and asked for concurrence from his colleagues. CDD/Gubman said that staff would schedule a study session to discuss navigating through the EIR to obtain information which is provided in a summary form for 6:00 p.m. prior to the regular June 25 meeting. The rest of the document is the technical basis for the summary information. C/Lin asked if staff prepared the EIR and CDD/Gubman said that the City contracted with a consultant who assembled a team of specialists in the various disciplines such as air quality, noise, traffic and biology to collectively provide the basis for the EIR and the document went through a collaborative effort that included staff and attorney review. C/Lin asked if it would be prudent to invite the consultant to attend the study session. CDD/Gubman said he would work on that issue. 10. SCHEDULE OF FUTURE EVENTS: As listed in tonight's agenda. ADJOURNMENT: With no further business before the Planning Commission, Chairman Nelson adjourned the regular meeting at 8:11 p.m. to June 25, 2013. The foregoing minutes are hereby approved this 25th day of June, 2013. Attest: Respectfully Submitted, Greg Gubman Community Development Director Steve Nelson, Chairman .T, PLANNING COMMISSION v ri� AGENDA REPORT CITY OF DIAMOND BAR - 21810 COPLEY DRIVE - DIAMOND BAR, CA 91765 - TEL. (909) 839-7030 - FAX (909) 861-3117 AGENDA ITEM NUMBER: MEETING DATE: CASE/FILE NUMBER: PROJECT LOCATION: PROPERTY OWNER/APPLICANT: 7.1 June 25, 2013 Development Review No. PL 2013-123 24069 Gold Rush Drive Diamond Bar, CA 91765 (APN 8701-018-031) Razgo Lee 24069 Gold Rush Drive Diamond Bar, CA 91765 Summary The applicant is requesting approval of a Development Review application to construct a 1,023 square -foot second story addition at the front of an existing two-story single family residence. The existing residence consists of 6,623 square feet of living area and 853 square -foot four -car garage on a 0.67 gross acre (29,138 square -foot) lot. The architectural style of the existing residence is Mediterranean with Italian Renaissance Revival influences. The proposed second -story addition will maintain design consistency, an appropriate relationship in mass and scale to the site, and incorporate existing design elements compatible with the surrounding neighborhood. After evaluating the submittal, staff finds that the proposed project complies with the City's development standards, and that the required Development Review findings set forth in the Development Code can be made in the affirmative. Therefore, staff recommends that the Planning Commission approve Development Review No. PL2013-123, based on the findings of fact, and subject to the conditions of approval contained in the attached Resolution. BACKGROUND: Site Description The project site is located on the north side of Gold Rush Drive, west of Highcrest Drive.

Development Review No. PL 2013-123 Page 3 of 6 ANALYSIS Development Review (DBMC Section 22.48) The purpose of a Development Review (DR) is to ensure that new development and additions to existing development are consistent with the General Plan "through the promotion of high functional and aesthetic standards to complement and add to the economic, physical, and social character" of Diamond. Bar. The process ensures that new development and intensification of existing development yields a pleasant living environment, and attracts the interest of residents and visitors as the result of consistent exemplary design. • Development Standards: The following table compares the proposed project with the City's development standards for residential development in the RL zone: Development Residential Development Existing Proposed Feature Standards Requirements 89'-10" 89'-10" Yes Front• • 20 feet 10 feet on one side and 6'-0" —east side 6'-0" —east side 5 feet on the other side. 10'-6" — west side 10'-6" — west side Yes 15 feet 164' — east side 16'-6" — east side Yes 43'-6" — west side 43'-6" — west side • 20 feet 105'-6" 105'-6" Yes • Maximum of 40% 16.9% 16.9% Yes • 35 feet 32'-5" 32'-5" Yes 2 -car garage 4 -car garage 4 -car garage Yes • Site and Grading Configuration: The proposed addition is located on the second story of an existing two-story residence. Therefore, there will be no grading on the site. • Architectural Features, Colors, and Materials: The architecture of the existing residence is Mediterranean with Italian Renaissance Revival influences, such as mission tile hipped roofs, arched windows, horizontal banding at the base, and Tuscan columns. The applicant is proposing to retain the existing building style. The proposed design will maintain architectural integrity by incorporating similar Development Review No. PL 2013-123 Page 4 of 6 fenestration patterns, and matching existing exterior colors and building materials. The roof of the proposed addition will be integrated with the existing roof by matching the existing hipped roof and 5:12 pitch. • Landscaping: Landscape plans are not required because the site is already developed, and because the project is exempt from the City's Water Conservation Landscaping Ordinance. The ordinance would only apply if 5,000 square feet or more of the existing landscaped area was being altered. However, landscaping that is damaged during construction will need to be restored upon project completion. This requirement is included as a condition of approval. Compatibility with Neighborhood The proposed project complies with the goals and objectives as set forth in the adopted General Plan in terms of land use and density. The project is designed to be compatible with and enhance the character of the existing homes in the neighborhood. The project incorporates the principles of the City's Residential Design Guidelines as follows: • The proposed building addition is visually integrated with the primary structure by using similar forms, colors, and materials; • The proposed roof type, pitch, and materials match those of the primary structure; • Window type and dimensions, and other architectural features, such as decorative bands, window trims, and columns, match those of the primary structure; and • Large wall expanses without windows or doors are avoided.

(909) 839-7030 - FAX (909) 861-3117 AGENDA ITEM NO. 7.2 MEETING DATE: June 25, 2013 CASE/FILE NUMBER: Development Review, Tentative Tract Map No. 72067, and Parking Permit (Planning Case No. PL2012-455) PROJECT LOCATION: 650 Brea Canyon Road (Los Angeles County Assessor's Parcel No. 8719-010-901) PROPERTY OWNER/ Peichin Lee of Brea Canyon Investments, LLC APPLICANT: 17528 E. Rowland Street #200 City of Industry, CA 91748 Summary The applicant is proposing to build a new two story professional office building on a vacant pad located at the northeast corner of Brea Canyon Road and Washington Street. This property was previously owned by the Alameda Corridor -East Construction Authority (ACE), and was disposed of as surplus property after the Brea Canyon Road underpass bridge construction at the railroad crossing in the cities of Industry and Diamond Bar. The following entitlements are being requested: 1. Development Review to construct a 21,794 square -foot, new two story professional office building on a 42,333 square -foot (0.97 acre) lot; 2. Tentative Tract Map No. 72067 to subdivide air space for an 11 -unit office condominium; and 3. Parking Permit to share driveway access and parking between the proposed development and the lot to the north of the project site. The building's architectural style is a contemporary modern style. The building is designed to incorporate principles of modern architecture by celebrating the capabilities of contemporary construction materials and technologies. After evaluating the application and related submittals, staff has determined that the proposed project complies with the City's development standards and the Subdivision Map Act, and believes that the Development Review, Tentative Tract Map, and Parking Permit findings set forth in the Development Code can be made in the affirmative. Therefore, staff recommends that the Planning Commission forward a recommendation to the City Council to approve the proposed Development Review, Tentative Tract Map and Parking Permit No. PL2012-455, based on the findings of fact, and subject to the conditions of approval contained in the attached Resolution. Background The project site is on a 0.97 -acre vacant parcel. It is on an elevated pad, approximately 13 feet higher than the centerline of Brea Canyon Road and Washington Street. The site was previously developed a 2,500 square -foot single family residence and garage. These structures were demolished around 2006, prior to the construction of the Brea Canyon Road Grade Separation project by ACE. The site was then used as a temporary access road to the Metrolink station. After completion of the grade separation project, the site was declared to be surplus property, and was then disposed of earlier this year when ACE sold it to the applicant. The project site is legally described as Parcel 1 of Parcel Map No. 16640, and the Assessor's Parcel Number (APN) is 8719-010-901. Proiect Description The applicant proposes to build a new two-story professional office building, with 11 units to be sold as office condominiums governed by an association. The unit sizes range from 1,268 to 2,108 square feet and two public restrooms are proposed on each floor. There will be 37 parking spaces provided on-site with additional parking spaces available on the existing lot to the north. The applicant is requesting a parking permit to share driveway access and parking between the proposed development and the existing lot to the north. Site and Surrounding General Plan, Zoning and Land Uses Site Light Industrial OP Vacant North Li ht Industrial I Warehouse and Offices Medium Density South Residential RM Multi -Family Residential East Li ht Industrial I Public Storage Facility West Light Industrial I Office Industrial Park Page 2 of 12 CD: Staff Reports PC/Brea Canyon Road 650 PC Staff Report 06-25-2013.docx ANALYSIS: Review Authority (Diamond Bar Municipal Code (DBMC) Sections 22.48, 21.20.080 and 22.30.050) The proposed project requires three entitlement applications for review. The Tentative Tract Map for the subdivision of land requires City Council approval. The Development Review for the site plan and architectural components of the project and Parking Permit to share parking and driveway access require Planning Commission approval. DBMC Section 22.48.030 of the Development Code requires all applications to be processed simultaneously by the highest review authority. Therefore, the Planning Commission's role in this matter is to forward a recommendation to the City Council for the three entitlements described below: Development Review (DBMC Section 22.48) The purpose of Development Review (DR) is to establish consistency with the General Plan through the promotion of high aesthetic and functional standards to complement and add to the economic, physical, and social character of the City. The process ensures that new development and intensification of existing development yields a pleasant living environment, and attracts the interest of residents and visitors as the result of consistent exemplary design. • Development Standards: The following table compares the proposed project with the City's development standards for commercial development in the OP zone: *The proposed project will provide adequate parking by means of a shared parking arrangement with the parcel to the north. The attached conditions of approval require a reciprocal parking and access agreement to be recorded with the final map. See discussion beginning on Page 8.

The attached conditions of approval require a reciprocal parking and access agreement to be recorded with the final map. See discussion beginning on Page 8. Page 4 of 12 CD: Staff Reports PC/Brea Canyon Road 650 PC Staff Report 06-25-2013.doex ® Site and Grading Configuration: The site is on an existing pad. Although the pad is leveled, the applicant is proposing to lower it by one foot, requiring some grading and excavation. An ADA accessible ramp is proposed within the landscaped slopes along Washington Street. The existing driveway, that runs along the easterly property boundary is proposed to be retained and incorporated into the site plan. Architectural Features, Colors, and Material: The City's Design Guidelines have been established to encourage a better compatible building and site design that improves the vital quality of the surrounding area through aesthetically pleasing site planning, building design, and architecture. In addition, a primary objective is to promote compatibility with adjacent uses to minimize any potential negative impacts. The architectural style is a contemporary modern style. The building is designed to incorporate principles of the modern architecture by its simplicity of building form and windows with nonsuperfluous details. In addition, the massing of the entrance/lobby area is taller than the other parts of the building and incorporates an alcove to the building entrance, bringing this element down to a human scale. The tall glazing openings have mullions to break up the big glass panels, and reveals are added on the elevations to break up the flat walls. The project incorporates the principles of the City's Commercial Design Guidelines as follows: ➢ Monotony of building design.as well as busyness is avoided. Variation in wall place, roof line, detailing materials are used to prevent monotonous appearance in buildings; ➢ Parapet walls are treated as an integral part of the building design; ➢ The exterior building design, including roof style, color, materials, architectural form and detailing is consistent on all elevations of each building to achieve design harmony and continuity within itself; ➢ Articulation and accent color for identity and interest is provided for the building entrance; and Contains elements which transition to the human scale, particularly near the ground. The north and east elevations feature a whimsical, asymmetrical arrangement of circular windows. The seeming randomness of the window placements, together with the varied window diameters, give the illusion that the building has no structural framing, and celebrate how space frames can be used to span large areas with few interior supports.

Existing landscaping along the slopes located along Brea Canyon Road and Washington Street will remain. The landscape will be enhanced by adding more trees, shrubs, and ground cover around the south and east sides of the property. Four 36 -inch box Brisbane Box and four 24 -inch box Camphor trees are proposed along Washington Street. In order to screen the proposed retaining walls around the accessible ramp and existing transformer, tall shrubs are being proposed. The three Mexican pale verde trees proposed adjacent to the driveway is recommended to be replaced with another non-invasive species. See Condition of Approval No. B.5 of the Draft Resolution (Attachment 1). All other plant types proposed are non-invasive plant species. The project is also required to comply with the new water -efficient landscape requirements, which will be verified during building plan check. Tentative Tract Map (Diamond Bar Municipal Code Section 21.20.0801 Pursuant to DBMC Section 66424 of the Subdivision Map Act, a Tentative Tract Map is required for the creation of a condominium or other interest development simultaneously with the construction of a new structure. There are 11 units proposed within the new two story office building, to be sold as condominiums and governed by an association. The two public restrooms on each floor as well as the lobby, hallways, and elevator will be part of the building's common areas. The property will have 37 parking spaces on-site to share with the lot to the north. The project is conditioned to submit Covenants, Conditions, and Restrictions (CC&R's) that govern the 11 units within the building, and is subject to review and approval by the City Attorney prior to the issuance of building permits. Parking Permit (DBMC Section 22.30.050) Pursuant to DBMC Section 22.30.050 of the Development Code, where two or more commercial uses are developed as a professional center and those uses have distinct and differing peak parking usage periods, a reduction in the required number of parking Page 7 of 12 CD: Staff Reports PC/Brea Canyon Road 650 PC Staff Report 06-25-2013.docx spaces may be allowed through the approval of a parking permit, provided that the most remote space is located within 300 feet of the use it is intended to serve (as measured along the most direct pedestrian path). The amount of reduction may be up to the amount of spaces required for the least intensive of the two or more uses sharing the parking. Professional offices are required to provide 1 parking space for every 400 square feet of gross floor area, medical offices are required to provide 1 space for every 250 square feet, and warehouse and storage facilities are required to provide 1 space for every 1,000 square feet. The existing gross floor area of the one story industrial office/warehouse building to the north is 20,571 square feet, and requires 31 parking spaces. The proposed development is required to provide 60 parking spaces. There are 37 spaces proposed to be provided on-site and the lot to the north has 54 spaces. Therefore the proposed development will comply with the parking code requirement by providing 91 spaces for both lots with a reciprocal parking agreement between the two lots. Parking Requirement The applicant submitted a draft reciprocal parking and access agreement governing the use and access of all common roads, driveways, parking, and easement areas. The agreement also prohibits semi -trucks from accessing the site due to the narrow width of the driveway. This prohibition would only allow smaller service/delivery trucks to access the site. The agreement will be reviewed and approved by the Planning Division and City Attorney's Office prior to final map approval. See Condition of Approval No. D.2 of the Draft Resolution (Attachment 1). Based on the traffic analysis report, the intersection capacity analysis for the intersection of Brea Canyon Road at Currier Road, Washington Street, Lycoming Street, SR -60 West Bound ramp intersections, and Golden Springs Drive at SR -East Bound ramps indicates that the proposed project will not have a significant traffic impact and is forecast to operate at Level of Service (LOS) D or better during peak hours. LOS D is the minimum level generally considered to be acceptable for urban intersections. The Page 8 of 12 CD: Staff Reports PC/Brea Canyon Road 650 PC Staff Report 06-25-2013.docx City of Diamond Bar's General Plan calls for LOS D as the minimum acceptable service level at an intersection, while LOS C is the minimum for roadway segments. The proposed project would not cause any intersections or street segments in the vicinity to operate at an unacceptable level of service. All intersections and roadway segments will continue to maintain an acceptable level of service. Therefore, no mitigation measures or improvements are required for the proposed project. Compatibility with Neighborhood The proposed project complies with the goals and objectives as set forth in the adopted General Plan in terms of land use. The project will not negatively affect the existing surrounding land uses, and the design and appearance of the proposed office building is compatible with the surrounding community. There is an office industrial park to the west, industrial office and warehouse building to the north, and a public storage facility to the east. Therefore, operational characteristics are compatible with the surrounding uses. There are multi -family homes to the south built on a much higher pad than the proposed development. In addition, Washington Street separates the multi -family homes from the proposed development. Multi -Family Homes to the South (View From Brea Canyon Road) Additional Review The Public Works/Engineering Department and Building and Safety Division reviewed this project and included their comments in the attached resolution as conditions of approval. Page .9 of 12 CD: Staff Reports PC/Brea Canyon Road 650 PC Staff Report 06-25-2013.docx NOTICE OF PUBLIC HEARING: Public hearing notices were mailed to property owners within a 500 -foot radius of the project site on June 13, 2013, and the notice was published in the Inland Valley Daily Tribune and San Gabriel Valley Tribune newspapers on June 14, 2013. The project site was posted with a notice display board, and a copy of the public notice was posted at the City's three designated community posting sites. Public Comments Received At the time the staff report was published, staff had not received any comments from the public. ENVIRONMENTAL ASSESSMENT: This project has been reviewed for compliance with the California Environmental Quality Act (CEQA). Based on that assessment, staff prepared and filed an Initial Study/Environmental Checklist and Notice of Intent to Adopt Negative Declaration for the project on May 23, 2013, with the Los Angeles County Clerk and published in the Inland Valley Daily Tribune and San Gabriel Valley Tribune newspapers, and it is part of this report (Attachment 2). Pursuant to CEQA Section 15105, the public review period for the Mitigated Negative Declaration began on May 31, 2013, and ended on June 20, 2013. The Initial Study is a preliminary analysis to determine whether or not a Negative Declaration, Mitigated Negative Declaration, or Environmental Impact Report (EIR) is needed for a project. If the Initial Study concludes that the proposed project will not significantly affect the environment, a Negative Declaration may be prepared. If there are potential impacts from the proposed project that can be mitigated to a level of less than significant, a Mitigated Negative Declaration may be prepared. A Mitigated Negative Declaration is a written document that briefly describes the reasons that a proposed project will not have a significant effect on the environment by properly conditioning the project ("mitigation measures") to make the project acceptable. It is used to guide and assist the City staff, Planning Commission, City Council, and the public in the consideration and evaluation of potential environmental impacts that may result from the proposed project. Once the Initial Study and Mitigated Negative Declaration are prepared, a Notice of Intent to Adopt a Mitigated Negative Declaration is posted at the Los Angeles County Clerk and published in the Inland Valley Daily Tribune and San Gabriel Valley Tribune newspapers. The public review period must be no less than 20 days. Staff prepared the Initial Study/Environmental Checklist for the proposed project, which documents reasons to support the findings that the proposed project would not have any potentially significant impacts on the environment with the proposed mitigation Page 10 of 12 CD: Staff Reports PC/Brea Canyon Road 650 PC Staff Report 06-25-2013.docx measures included. The project is conditioned to include these mitigation measures as part of project approval. See Attachment A of Attachment 2: Mitigation and Monitoring Program. RECOMMENDATION: Staff recommends that the Planning Commission adopt the attached Resolution (Attachment 1) recommending approval of the Development Review, Tentative Tract Map, and Parking Permit for Project No. PL2012-455 to the City Council, to allow the construction of a new two story professional office building, based on the findings of DBMC Sections 22.48, 21.20.080 and 22.30.050, subject to conditions of approval as listed within the draft resolution.

The building is also consistent with the City's Commercial Design Guidelines Pages 8-13, which incorporates the following principles: ➢ Monotony of building design as well as busyness is avoided. Variation in wall place, roof line, detailing materials are used to prevent monotonous appearance in buildings; ➢ Parapet walls are treated as an integral part of the building design; ➢ The exterior building design, including roof style, color, materials, architectural form and detailing is consistent on all elevations of each building to achieve design harmony and continuity within itself; ➢ Articulation and accent color for identity and interest is provided for the building entrance; and ➢ Contains elements which transition to the human scale, particularly near the ground. The project site is not a part of any theme areas, specific plans, community plans, boulevards or planned developments. 2. The design and layout of the proposed development will not interfere with the use and enjoyment of neighboring existing or future developments, and will not create traffic or pedestrian hazards: The proposed building will not interfere with the use or enjoyment of neighboring existing or future developments because the use of the project site is designated for commercial uses and surrounded by commercial uses to the north, east and west. The proposed building will not interfere with vehicular or pedestrian movements, such as access or other functional requirements. A traffic analysis report concluded that the proposed project would not cause any intersections or street segments in the vicinity to operate an unacceptable level of service. All intersections and roadway segments will continue to maintain an acceptable level of service. in addition, the project site is prohibited from semi -trucks 3 Planning Commission Resolution No. 2013 -XX accessing the site due to the narrow width of the driveway. This prohibition would only allow smaller service/delivery trucks to access the site. The project is conditioned to include this prohibition in the Covenants, Conditions, and Restrictions as well as the reciprocal parking and access agreement, subject to review and approval by the Planning Division, Public Works/Engineering Department and City Attorney. 3. The architectural design of the proposed development is compatible with the character of the surrounding neighborhood and will maintain and enhance the harmonious, orderly and attractive development contemplated by this chapter, the general plan, or any applicable specific plan: The architectural style is a contemporary modern style and is designed to be compatible with the character of the neighborhood and further enhances the visual quality of the neighborhood. There is no specific plan for the project area. 4. The design of the proposed development will provide a desirable environment for its occupants and visiting public as well as its neighbors through good aesthetic use of materials, texture and color, and will remain aesthetically appealing: The design of the new proposed building is a contemporary modern style of architecture. Variation in the building elements has been achieved through the utilization of varying architectural features such as higher parapet walls for the lobby entrance, tall storefront glazing at the rear corner of the building, reveals on the elevations, and different use of building colors and materials. The project has a sense of balance, involving well-proportioned masses and composition. The incorporation of an alcove for the entrance/lobby area brings the building to an intimately scaled, human level. 5. The proposed development will not be detrimental to the public health, safety or welfare or materially injurious (e.g., negative effect on property values or resale(s) of property) to the properties or improvements in the vicinity: Before the issuance of any City permits, the proposed project is required to comply with all conditions within the approved resolution, and the Building and Safety Division and Public Works Departments, and L.A. County Fire Department requirements. The referenced agencies through the permit and inspection process will ensure that the proposed project is not detrimental to the public health, safety or welfare or materially injurious to the properties or improvements in the vicinity. 6. The proposed project has been reviewed in compliance with the provisions of the California Environmental Quality Act (CEQA): Staff prepared an initial study and determined that the proposed project qualifies for a Mitigated Negative Declaration as the proposed project will not have a significant effect on the environment by properly conditioning the project ('mitigation measures') to make the project acceptable. In accordance to the 4 Planning Commission Resolution No. 2013 -XX provisions of Section 15070 of the CEQA Guidelines, the City prepared and Ned a Notice of Availability and Intent to Adopt Mitigated Negative Declaration for the project on May 23, 2013, with the Los Angeles County Clerk. Pursuant to CEQA Section 15105, the public review period for the Negative Declaration began May 31, 2013, and ended June 20, 2013, Tentative Map Findings: Pursuant to Subdivision Code Section 21.20.080 of the City's Subdivision Ordinance, the Planning Commission makes the following findings: 1. The proposed subdivision, together with the provisions for its design and improvement, is consistent with the general plan and any applicable specific plan: The proposed project involves the condominium subdivision of the site with 11 office units, and approximately 0.72 acres of parking areas, driveway easements, and landscaping. The General Plan land use designation for the site is Light Industrial (I). The proposed project is consistent with the General Plan land use designation. The project site is not a part of any specific plan. 2. The site is physically suitable for the type and proposed density of development: The proposed condominium subdivision will be consistent with the General Plan land use designation of Light Industrial, which allows for the development of 11 office units in a 21,794 square -foot building. The building will have an approximately 52' setback from Brea Canyon Road and 20' from Washington Street and is located within an urbanized area adequately served by existing roadways and infrastructure. Therefore the property is physically able to accommodate the proposed development. 3. The design of the subdivision or the proposed improvements will not cause substantial environmental damage or injure fish or wildlife or their habitat: The design of the subdivision or the proposed improvements will not cause substantial environmental damage or injure fish or wildlife or their habitat because the existing site is located in an urbanized area that does not contain habitats or would otherwise injure fish or wildlife or their habitat. 4. The design of the subdivision or type of improvements will not cause serious public health or safety problems: The proposed subdivision or type of improvements are not likely to cause serious public health or safety problems because the existing site is located in an urbanized area and is consistent with other similar improvements in the area. 5. The design of the subdivision or type of improvements will not conflict with easements, acquired by the public at large for access through or use of, property within the proposed subdivision: 5 Planning Commission Resolution No. 2013 -XX A condition of approval is added to the project requiring a reciprocal parking and access agreement with the existing lot to the north of the project site for the use and access of all common roads, driveways, parking, and easement areas, prior to final map approval. 6. The discharge of sewage from the proposed subdivision into the community sewer system would not result in violation of existing requirements prescribed by the California Regional Water Quality Control Board: The project site shall be served by a separate sewer lateral which shall not cross any other lot lines. In the event that it is determined that each lot is not serviced by a separate independent sewer lateral, joint sewer maintenance and sewer line easements which cross the lot lines shall be identified in the joint agreements between properties. Therefore, no further environmental review is required. The applicant shall construct the sewer system in accordance with the City Building and Safety Division and County Sanitation District Standards prior to building occupancy. 7. A preliminary soils report or geologic hazard report does not indicate adverse soil or geologic conditions: The existing pad was previously improved with buildings. Further grading will be constructed, operated, and maintained in accordance with the recommendations contained in the preliminary geotechnical investigation to assure that geotechnical stability is maintained or increased. 8. The proposed subdivision is consistent with all applicable provisions of the City's subdivision ordinance, the development code, and the subdivision map act: The proposed subdivision is consistent with the City's subdivision ordinance, subdivision map act, and applicable development code. The proposed building complies with all required setbacks and development code regulations. Parking Permit Findings (DBMC Section 22.30.050) The intent of the parking regulations, which is to ensure that sufficient parking will be provided to serve the use intended and potential future uses of the subject site, is preserved: The proposed professional office building is 21,794 square feet, and requires 60 parking spaces. The existing gross floor area of the one story industrial office/warehouse building to the north of the project site is 20,571 square feet, and requires 31 parking spaces. There are 37 spaces proposed to be provided on the project site and the lot to the north has 54 spaces. Therefore, there will be 91 spaces, and will comply with the requirement. A parking permit is approved in compliance with Section 22.30.050 (Reduction of off-street parking requirements for shared uses): 6 Planning Commission Resolution No. 2013 -XX When reviewing parking impacts, the various uses and peak business hours for those uses are taken into consideration. The existing industrial office and warehouse building and the proposed office building have different uses which results in a range of peak business hours and parking demands. In addition, the proposed parking spaces as well as the existing parking supply to the north of the project site are adequate and can accommodate shared spaces. Due to this, staff does not foresee any parking issues resulting from the proposed use. In addition, the property to the north of the project site is not heavily congested or utilized. Based on the findings and conclusions set forth herein and as prescribed under DBMC Sections 21.20.080 and 22.30.050, this Planning Commission hereby finds and recommends that the City Council adopt the Mitigated Negative Declaration and approve the Development Review, Tentative Tract Map and Parking Permit, subject to the following conditions, and the attached Standard Conditions of Approval: A.

Page 2 2) All answers must take account of the whole action involved, including off-site as well as on-site, cumulative as well as project -level, indirect as well as direct, and construction as well as operational impacts. 3) Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less than significant with mitigation, or less than significant. "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect is significant. If there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required. 4) "Negative Declaration: Less Than Significant With Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less than Significant Impact." The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section XVII, "Earlier Analyses," may be cross-referenced). 5) Earlier analyses may be used where, pursuant to the tiering, program FIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063(c)(3)(D). In this case, a brief discussion should identify the following: a.) Earlier Analysis Used. Identify and state where they are available for review. b.) Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. C.) Mitigation Measures. For effects that are "Less than Significant with Mitigation Measures Incorporated," describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project. 6) Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, including a reference to the page or pages where the statement is substantiated. 7) Supporting Information Sources: A source list should 'be attached, and other sources used or individuals contacted should be cited in the discussion. 8) This is only a suggested form, and lead agencies are free to use different formats; however, lead agencies should normally address the questions from this checklist that are relevant to a project's environmental effects in whatever format is selected. 9) The explanation of each issue should identify: a) The significance criteria or threshold, if any, used to evaluate each question; and b) The mitigation measure identified, if any, to reduce the impact to less than significance.

Would the project: a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps X prepared pursuant to the Farmland Mapping and Monitoring X Program of the California Resources Agency, to non-agricultural use? Impact Discussion: The project site is not designated as Prime Farmland, Unique Farmland or Farmland of Statewide Importance. There are no agricultural activities on or near the proposed project site. Project implementation would not result in the conversion of farmland to non-agricultural use. Therefore the proposed project would have no impacts to farmlands. b) Conflict with existing zoning for agricultural use, or a X Williamson Act contract Impact Discussion: Implementation of the proposed project would not conflict with existing zoning for agricultural use, or a Williamson Act contract. Therefore no impacts would result from the construction or operation of the proposed project. c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code Section 12220(g)), timberland (as defined by Public Resources Code Section X 4526), or timberland zoned Timberland Production (as defined by Government Code Section 51104(g))? Impact Discussion: There are no forestland, timberland or timberland zoned Timberland Production uses that are occurring on-site or in the immediate vicinity. Thus, the proposed project does not involve changes in the existing environment that could conflict with existing zoning or cause of rezoning of forestland, timberland, or timberland zoned Timberland Production. d) Result in the loss of forest land or conversion of forest land to X non -forest use? Impact Discussion: There are no forest land uses that are occurring on-site or in the immediate vicinity. There is minimal amount of vegetation within the area, and no protected trees are located on-site. Thus, the proposed project does not involve changes in the existing environment that could result in loss of forest land or conversion of forest land to non -forest use.

Where available, the significant criteria established by the applicable air quality management or air pollution control district may be relied upon to make the following determinations. Would the project: a) Conflict with or obstruct implementation of the applicable air X quality Ian? b) Violate any air quality standard or contribute substantially to an X existing or projected air quality violation? c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non -attainment X under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors ? rl) Expose sensitive receptors to substantial pollutant X Impact Discussion for a -d: The proposed project does not involve long-term changes to land use or other growth -inducing actions that could impact compliance with or implementation of the Air Quality Management Plan. The construction of a 21,794 square -foot commercial office building will exceed the thresholds for maximum daily construction emissions for pollutants and therefore mitigation is required and included below. After the completion of the construction activities, it is not anticipated that there will be an increase in emissions from operational activities of a 21,794 square -foot commercial office building. A 21,794 square -foot commercial office building falls well below thresholds for maximum daily operation emissions of 96,221 square feet as defined in Table 6-2 of the South Coast Air Quality Management District CEQA Air Quality Handbook for criteria pollutants. Therefore, impacts from operational activities would be less than significant. Mitigation Measures The following mitigation measure will be implemented during demolition and construction activities, consistent with South Coast Air Quality Management District Rule 403 in order to reduce PM10 and PM 2.5, emissions. The project will be conditioned to include these mitigation measures, and the developer shall be required to include in contract specifications, indicate on project grading and construction plans, and post at the jobsite. Compliance with these measures will be subject to periodic site inspections by the City. Page 6 AQ -1 Prior to the issuance of grading permits, the applicant shall develop and submit to the City of Diamond Bar a Comprehensive Construction Dust Control Program. The Program components shall include but not be necessarily limited to the following: • Trucks shall not idle while awaiting or during loading or offloading operations, or when left unattended, or for more than two minutes when not actively engaged in earthwork operations; • Water exposed surfaces frequently (as necessary) to prevent fugitive dust, at least twice daily; • Cover all stockpile of soil/fill with tarps; • Securely cover loads of soil/fill on trucks hauling dirt with tarps before traveling on streets and highways; and • Sweep streets at the end of the day if visible soil material is carried onto adjacent public paved road (recommend water sweepers with reclaimed water). e) Create objectionable odors affecting a substantial number of X people? Impact Discussion: The proposed project will result in the development of a 21,794 square -foot office building. The proposed project is therefore not expected to generate objectionable odors affecting a substantial number of people. Construction activity associated with the proposed project may generate detectable odors from heavy-duty equipment exhaust. However this impact would be short- term in nature (only during construction activities) and cease upon project completion. - Potentially habitat modifications, on any species identified as a candidate, Potentially Significant Less than No sensitive, or special status species in local or regional plans, Significant Unless Significan Impact p policies, or regulations, or by the California Department of Fish Impact Mitigation t Impact ISSUES Incorporated e) Create objectionable odors affecting a substantial number of X people?

Impact Discussion: The project site is located on a vacant lot. It is not located in an area likely to have historical, archaeological, or paleontological resources. The proposed project may have a significant adverse impact if it would cause a substantial adverse change in the significance of a historical resource as defined in Section 15064.5 of the CEQA Guidelines. This section of the CEQA Guidelines defines a historical resource as one listed in or eligible for listing in the California Register of Historical Places (per state law), included in a local register of historical resources (as defined by state law) or identified as significant in an historical resource survey (meeting the requirements of state law) or determined by the lead agency (City of Diamond Bar) to be historically significant or significant in the architectural, engineering, scientific, economic, agricultural, educational, social, political, military, or cultural annals of California, provided the determination is supported by substantial evidence in light of the whole record. Generally, a resource shall be considered by the lead agency to be "historically significant' if the resource meets the criteria for listing on the California Register of Historical Places. In this case, the existing site is not listed in nor eligible for listing in the California Register of Historical Places, not listed in a local registrar of historical resources or identified as significant in an historical resource survey, nor has it been determined to be historically significant by the City because it does not meet the criteria for listing on the California Register of Historical Places. Therefore, it does not meet the definition of a historical resource contained in Section 15064.5 of the CEQA Guidelines and is therefore less than significant impact. d) Disturb any human remains, including those interred outsideof X formal cemeteries?

Would the project: Potentially I Significant I Less thanI No Significant Unless Significan Impact Impact Mitigation IImpact Expose people or structures to potent�ial substantial adverse affects, including the risk of loss, injuiry, or death involving: i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map x issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42. Impact Discussion: No active faults are known to traverse the project site and the project site is not located within, or immediate adjacent to an Alquist-Priolo Earthquake Fault Zone. Therefore, rupture of a known earthquake fault would not occur within the project area. Adherence to standard engineering practices and design criteria relative to seismic and geologic hazards in accordance with the 2010 California Green Building Standards Code (CALGreen) is required. Conformance to these requirements would be applied to the proposed project as standard conditions of project approval. ii) Strong seismic ground shakin ? X Impact Discussion: Southern California has numerous active and potentially active faults that could produce strong ground shaking that could impact the project site. The City of Diamond Bar is in proximity to the San Andreas and Sierra Madre Fault zone. The 2010 California Green Building Standards Code (CALGreen) requires structural design and construction methods that minimize the effects of strong seismic ground shaking. The CALGreen requirements would be applied to the proposed project as standard conditions of project approval. Impact Discussion: The project area is located within a portion of the City that is not subject to liquefaction. Therefore project implementation is not anticipated to result in the exposure of people or structures to potential impacts related to seismic ground failure or liquefaction. Impact Discussion: The proposed project required the submittal and approval of a preliminary geotechnical investigation report. This report indicated that the project site is suitable for the development of a two-story commercial office building with the recommendations in the report incorporated into the project's design and job specification. Therefore, the potential for seismically - related landslides is less than significant. n substantial soil erosion or the loss of Impact Discussion: The largest source of erosion, particularly in an urban environment is uncontrolled drainage during construction. Erosion potential during construction would be managed to the maximum extent practicable with Best Management Practices (BMPs). The proposed project is required to be covered under the National Pollutant Discharge Elimination System (NPDES) General Construction Permit; therefore construction BMPs would be implemented on the project site during demolition and construction activities to minimize erosion impacts. Implementation of the construction -related BMPs would reduce potential construction -related impacts to the maximum extent feasible. The operation of the project site would not cause the loss of topsoil or erosion because the site would be landscaped and paved.

The report indicates that with the recommendations in the report incorporated into the project's design and job specification, the subject site is suitable for the development of a two-story commercial office building. The potential of an on-site and off-site landslide, liquefaction, lateral spreading or collapse is not likely. Therefore, the proposed project would result in less than significant impacts related to development on an unstable soil unit. d) Be located on expansive soil, as defined in Table 1804.2 of theF= Potentially California Building Code (2007), creating substantial risks to Potentially Significant X I X life or property? Significant Unless Significan Impact Impact Discussion: As described above, the project site is stable. Soil under the project site was investigated and the geotechnical investigation report indicates that the incorporation of recommendations into the project's design and job specification, the subject site is suitable for the development of a two-story office building. Therefore, potential impacts from expansive soils would be less than significant. e) Have soils incapable of adequately supporting the use of Potentially septic tanks of alternative waste water disposal systems Potentially Significant Less than X where sewers are not available for the disposal of waste Significant Unless Significan Impact water?

Would the project: a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the X environment? b) Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of greenhouse X ries? Impact Discussion for a and b: Many of the world's leading scientific experts agree that greenhouse gases (GHGs) generated by human activities affect climate by increasing the "greenhouse effect." The gases concentrate in the Earth's atmosphere and trap heat by blocking some of the long -wave energy the Earth normally radiates back into space. Human activities that produce GHGs are the burning of fossil fuels (coal, oil and natural gas for heating and electricity, gasoline and diesel for transportation); methane from Page 11 landfill wastes and raising livestock, deforestation activities; and some agricultural practices. These activities are increasing the greenhouse gases in the Earth's atmosphere and could be accelerating global climate change. _ Long-term environmental consequences in California could potentially include a reduction in water supply from the Sierra Nevada snow pack, which could result in a reduction in imported water, and public health problems due to degraded air quality and more intense summer heat. In 2006, Governor Schwarzenegger signed AB 32, the California Climate Solutions Act of 2006. AB 32 requires that statewide GHG emissions be reduced to 2000 levels by the year 2010, 1990 levels by the year 2020, and to 80 percent less than 1990 levels by year 2050. These reductions will be accomplished through an enforceable statewide cap on GHG emissions that will be phased in starting in 2012. To effectively implement the cap, AB 32 directs the California Air Resources Board (GARB) to develop and implement regulations to reduce statewide GHG emissions from stationary sources. AB 32 specifies that regulations adopted in response to AB 1493 should be used to address GHG emissions from vehicles. However, AB 32 also includes language stating that if the AB 1493 regulations cannot be implemented, then CARB should develop new regulations to control vehicle GHG emissions under the authorization of AB 32. AB 32 requires that CARB adopt a quantified cap on GHG emissions representing 1990 emissions levels and disclose how it arrives at the cap; institute a schedule to meet the emissions cap; and develop tracking, reporting, and enforcement mechanisms to ensure that the state achieves reductions in GHG emissions necessary to meet the cap. In 2007, CARB adopted the statewide 2020 emissions cap at 427 million metric tons (MMT) equivalent carbon dioxide (CO2e) greenhouse gas emissions. CARB estimated that 2020 'business -as -usual' emissions (meaning, emissions of greenhouse gases without consideration of climate change) would be 596 MMTCO2e; therefore, emissions will need to be reduced by 169 MMTCO2e (28 percent) statewide to meet the 2020 threshold. AB 32 also includes guidance to institute emissions reductions in an economically efficient manner and conditions to ensure that businesses and consumers are not unfairly affected by the reductions. A numerical threshold to determine the significance of greenhouse gas emissions has not been established by the City or SCAQMD. Global climate change is not confined to a particular project area and is generally accepted as the consequence of global industrialization over the last 200 years. A typical project, even a very large one, does not generate enough greenhouse gas (GHG) emissions on its own to influence global climate change significantly; hence the issue of global climate change is, by definition, a cumulative environmental impact. The State of California, through its governor and legislature, has established a comprehensive framework for the substantial reduction of GHG emissions over the next 40 -plus years. This will occur primarily through the implementation of AB32 and Senate Bill 375 (SB375), which will address GHG emissions on a statewide, cumulative basis. Nevertheless, the currently proposed project is not expected to generate potentially significant greenhouse gases by developing a 21,794 square -foot commercial office building. Therefore, no new significant impacts are anticipated and no mitigation measures are necessary at this time. Page 12 VIII. HAZARDS AND HAZARDOUS MATERIALS.

Impact Discussion: A traffic impact analysis (TIA) was prepared for this project. The study found that the proposed project would not result in significant impacts to the Brea Canyon Road at Currier Road, Washington Street, Lycoming Street, SR -60 West Bound ramp intersections, and Golden Springs Drive at SR -East Bound ramps. These intersections are projected to operate at Level of Service (LOS) D or better during peak hours. LOS D is the minimum level generally considered to be acceptable for urban intersections. The City of Diamond Bar's General Plan calls for LOS D as the minimum acceptable service level at an intersection, while LOS C is the minimum for roadway segments. According to CMP Guidelines, the minimum acceptable service level at CMP intersections is LOS E. A project would be considered significant if the LOS changed from D or better to and E or F. b) Conflict with an applicable congestion management program, including, but not limited to level of service standards and travel demand measures, or other standards established by X the county congestion management agency for designated roads or highways?

MANDATORY FINDINGS OF SIGNIFICANCE. a) Does the project have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or state, federal, and local statutes and Potentially Potentially Significant Less thanFoSignificant Unless Significan Impact Mitigation t Impact FA Impact Discussion: The project site does not contain the habitat of a fish or wildlife species and therefore construction of the proposed project would not cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, or reduce or restrict the range of a rare or endangered plant or animal. Likewise, approval of the proposed project is not anticipated to eliminate examples of major periods of California history or prehistory. Does the project have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerable means that the incremental effects of a project are X considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)? Impact Discussion: The cumulatively considerable impacts of the individually limited project are not expected to be significant and are in keeping with the long-range considerations of the City's General Plan. With the conditions of project approval and proposed mitigation measure, the cumulative impact of the individually limited project impacts will not be considerable. c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? X Impact Discussion: With the conditions of project approval and proposed mitigation measure, no substantial direct or indirect adverse environmental effects on human beings can be expected from this project.

The project site is a rectangular -shared 2.68 -acre vacant parcel of land that is located on the northeast corner of Washington Street and Brea Canyon Road This report documents the findings of a traffic impact analysis conducted by Linscott, Law & Greenspan, Engineers (LLG) to determine the potential impacts associated with the proposed Project. The traffic analysis evaluates the existing operating conditions at five (5) key study intersections within the project vicinity, estimates the trip generation potential of the proposed Project, and superimposes the project -related traffic volumes on the circulation system as it currently exists. In addition, the analysis forecasts future near-term and long-term operating conditions with and without the Project, and where necessary, identifies appropriate intersection improvements/ mitigation measures. The Project site has been visited and an inventory of adjacent area roadways and intersections was performed. Existing peak hour traffic information has been collected at five (5) locations on a "typical" weekday for use in the preparation of intersection level of service calculations. Information concerning cumulative projects (planned and/or approved) in the vicinity of the Project has been researched at the City of Diamond Bar, City of Walnut, City of Pomona, City of Industry and County of Los Angeles. Based on our research, eight (8) planned projects were considered in the cumulative traffic analysis for this Project. The Scope of Work for this Project was coordinated with City staff and satisfies the City of Diamond Bar requirements as outlined in the Tiaffie Impact Analysis Guidelines (Remised October 2009) and is consistent with the current Congestion Management Program (CMP), for Los Angeles County and the State of California Department of Transportation (Caltrans) Guide for the Preparation of Traffic biipact Studies. Appendix A contains a copy of the Scope of Work that was approved by the City of Diamond Bar.

The two freeways intersect one another in the northwest quadrant of the City. Primary access to the Project site is provided via the Golden Springs Drive/Brea Canyon Road/SR-60 Freeway Interchange. The local street network within the City of Diamond Bar that services the project includes Valley Boulevard, Currier Road, Brea Canyon Road, Washington Street, Lycoming Street and Golden Springs Drive. The following discussion provides a brief synopsis of these key area streets. The descriptions are based on an inventory of existing roadway conditions. Valley Boulevard is a five -lane, divided roadway located north of the project site and is oriented in the east -west direction. The posted speed limit on Valley Boulevard within the vicinity of the project site is 45 mph. On -street parking is not permitted along this roadway. Currier Road is a four -lane, divided roadway located north of the project site and is oriented in the east -west direction. This roadway provides a direct connection between Brea Canyon Road and Lemon Avenue. The posted speed limit on Currier Road is 40 mph. On -street parking is not permitted along this roadway. Brea Canyon Road is generally a four -lane, divided roadway located west of the project site and is oriented in the northeast -southwest direction. The posted speed limit on Brea Canyon Road is ranges from 40 - 50 miles per hour (mph) in the vicinity of the project. On -street parking is not permitted along this roadway in the vicinity of the project. Traffic signals control the study intersections of Brea Canyon Road at Currier Road, Washington Street, Lycoming Street, and SR -60 Westbound Ramps. Washington Street is a four -lane, divided roadway located south of the project site and is oriented in the east -west direction. The posted speed limit on Washington Street east of the project site is 35 mph. On -street parking is permitted along this roadway. Lycoming Street is a two-lane, undivided roadway located south of the project site and is oriented in the east -west direction. The posted speed limit on Lycoming Street is 35 mph west of Brea Canyon Road in the vicinity of the project. On -street parking is permitted along this roadway. Golden Springs Drive is a four -lane, divided roadway located south of the project site and is oriented in the east -west direction. The posted speed limit on Golden Springs Drive is 40 mph. Traffic signals control the study intersections of Golden Springs Drive at SR -60 EB Ramps.

The traffic counts of the three study intersections were conducted in June and October of 2012 and February 2013 by Transportation Studies, Inc and Pacific Traffic Data Services. Figures 3-2 and 3-3 depict the existing AM and PM peak hour traffic volumes at the key study intersections, respectively. Append& A contains the existing intersection turning movement traffic count data. 3.3 Existing Intersection Conditions 3.3.1 Intersection Capacity Utilization (ICU) Method of Analysis In conformance with the City of Diamond Bar and LA County CMP requirements, existing AM and PM peak hour operating conditions for the key signalized study intersections were evaluated using the Intersection Capacity Utilization (ICU) method. The ICU technique is intended for signalized intersection analysis and estimates the volume to capacity (V/C) relationship for an intersection based on the individual V/C ratios for key conflicting traffic movements. The ICU numerical value represents the percent signal (green) time, and thus capacity, required by existing and/or future traffic. It should be noted that the ICU methodology assumes uniform traffic distribution per intersection approach lane and optimal signal timing. The ICU calculations use a lane capacity of 1,600 vehicles per hour (vph) for left -turn, through, and right -turn lanes, and dual left turn capacity of 2,880 vph. A clearance adjustment factor of 0.10 (101/6) was added to each Level of Service calculation. The ICU value translates to a Level of Service (LOS) estimate, which is a relative measure of the intersection performance. The six qualitative categories of Level of Service have been defined along with the corresponding ICU value range and are shown in Table 3-1. The ICU value is the sum of the critical volume to capacity ratios at an intersection; it is not intended to be indicative of the LOS of each of the individual turning movements. According to the City of Diamond Bar, LOS D is the minimum acceptable service level that should be maintained during the peak commute hours. Consistent with this standard, the City of Diamond Bar's General Plan and Traffic Impact Analysis Guidelines (Revised October 2009) specifies LOS D as the minimum acceptable service level at intersections.

For all -way stop -controlled intersections, this methodology estimates the average control delay for each of the subject movements and determines the level of service for each movement. The overall average control delay measured in seconds per vehicle, and level of service is then calculated for the entire intersection. The HCM control delay value translates to a Level of Service (LOS) estimate, which is a relative measure of the intersection performance. For one-way and two-way stop -controlled (minor street stop -controlled) intersections, this methodology estimates the worst side street delay, measured in seconds per vehicle and determines the level of service for that approach. The HCM delay value translates to a Level of Service (LOS) estimate, which is a relative measure of the intersection performance. The six qualitative categories of Level of Service have been defined along with the corresponding HCM control delay value range, as shown in Table 3-2. 3.4 Existing Level of Service Results Table 3-3 summarizes the existing peak hour service level calculations for the five key study intersections based on existing traffic volumes presented in Figures 3-2 and 3-3, current street geometry, and intersection traffic control. As shown, all of the five key intersections currently operate at satisfactory levels of service (i.e., LOS D or better) during the AM and PM peak hours.

The first step is traffic generation, which estimates the total arriving and departing traffic on a peak hour and daily basis. The traffic generation potential is forecast by applying the appropriate vehicle trip generation equations or rates to the project development tabulation. The second step of the forecasting process is traffic distribution, which identifies the origins and destinations of inbound and outbound project traffic. These origins and destinations are typically based on demographics and existing/expected future travel patterns in the study area. The third step is traffic assignment, which involves the allocation of project traffic to study area streets and intersections. Traffic assignment is typically based on minimization of travel time, which may or may not involve the shortest route, depending on prevailing operating conditions and travel speeds. Traffic distribution patterns are indicated by general percentage orientation, while traffic assignment allocates specific volume forecasts to individual roadway links and intersection turning movements throughout the study area. With the forecasting process complete and project traffic assignments developed, the impact of the Project is isolated by comparing operational (LOS) conditions at selected key intersections using expected future traffic volumes with and without forecast project traffic. The need for site-specific and/or cumulative local area traffic improvements can then be evaluated.

Generation factors and equations used in the traffic forecasting procedure can be found in the 9t1i Edition of Trip Generation, published by the Institute of Transportation Engineers (ITE) [Washington, D.C., 2012]. Table 5-1 summarizes the trip generation rates used in forecasting the vehicular trips generated by the proposed Project and presents the forecast daily and peak hour project traffic volumes for a "typical" weekday. The trip generation potential for the proposed Project was forecast using ITE Land Use Code 710: General Office Building and ITE Land Use Code 720: Medical -Dental Office Building. As shown in Table 5-1, the proposed Project is forecast to generate 326 daily trips, with 37 trips (32 inbound, 5 outbound) produced in the AM peak hour and 39 trips (8 inbound, 31 outbound) produced in the PM peak hour on a "typical" weekday. 5.2 Project Traffic Distribution and Assignment The general, directional traffic distribution pattern for the proposed Project is presented in Table 5-2. Project traffic volumes both entering and exiting the site have been distributed and assigned to the adjacent street system based on the following considerations: • location of site access points in relation to the surrounding street system, • location of parking areas, and ingress/egress availability at the parking areas, • the site's proximity to major traffic carriers and regional access routes, • physical characteristics of the circulation system such as lane channelization and presence of traffic signals that affect travel patterns, • presence of traffic congestion in the surrounding vicinity, and • input from City staff. Based upon these considerations, the Project traffic distribution pattern at the key study intersections are presented on Figure 5-1. The anticipated AM and PM peak hour Project volumes associated with the proposed Project are presented in Figures 5-2 and 5-3, respectively. The traffic volume assignments presented in Figures 5-2 and 5-3 reflect the traffic distribution characteristics shown in Figure 5-1 and the Project traffic generation forecast presented in Table 5-1.

The ambient traffic growth factor is intended to include unknown and future related projects in the study area, as well as account for regular growth in, traffic volumes due to the development of projects outside the study area. Background traffic in the study area has been estimated to increase at a rate of approximately 1% per year in the near term. For the Year 2014, the existing (Year 2012) traffic volumes were increased by 2% to reflect area -wide regional growth in traffic. 6.2 Cumulative Projects Traffic Characteristics In order to make a realistic estimate of future on -street conditions prior to implementation of the proposed Project, the status of other known development projects (cumulative projects) within a two-mile radius of the proposed project has been researched at the City of Diamond Bar, City of Walnut, City of Pomona, City of Industry and County of Los Angeles in November 2012. With this information, the potential impact of the proposed Project can be evaluated within the context of the cumulative impact of all ongoing development. Based on our research, there are eight cumulative projects within the vicinity of the project. These cumulative projects have either been built, but not yet fully occupied, or are being processed for approval. These eight related projects have been included as part of the cumulative background setting. It should be noted that given the trip generation potential of the Industry Business Center (IBC), identified as cumulative project no, 4, is greater than that of the IBC/NFL Stadium altematives, the IBC project was considered in the cumulative analysis under long-term conditions. Table 6-1 provides a brief description for each of the eight related projects. Figure 6-1 graphically illustrates the location of the eight related projects. These related projects are expected to generate vehicular traffic, which may affect the operating conditions of the key study intersections. Table 6-2 summarizes the trip generation potential for all eight cumulative projects on a daily and peak hour basis for a typical weekday. As shown, the cumulative projects are expected to generate 87,104 daily trips, with 6,356 trips (5,003 inbound, 1,353 outbound) anticipated during the AM peak hour and 8,891 trips (2,990 inbound, 5,901 outbound) produced during the PM peak hour. Table 6-2 identifies that all of the eight cumulative projects are anticipated to be operational sometime after near term -year 2014 and before long-term Year 2034. 5 Source: Trcffic InipactAiial)sisforindttsn-),Bnsiness Center SEIIL prepared by LLGEngineeis, dated August 2008.

The previously discussed capacity analysis procedures were utilized to investigate the future volume -to -capacity relationships and service level characteristics at each study intersection. The significance of the potential impacts of the Project at each key intersection was then evaluated using the following traffic impact criteria 7.1 Impact Criteria and Thresholds: 7.1.1 City of Diamond Bar The significance of the potential impacts of the Project at each key intersection was then evaluated using the following criteria. The Project is considered to have a potentially significant impact if the following criteria are met: For Signalized Intersections: ❑ the ICU value under "with project" conditions is 0.91 or greater (LOSE or F), and ❑ the ICU increase attributable to the project is 0.02 or greater For Unsienalized Intersections: Based on the HCM/LOS method of analysis, this report identifies a significant traffic impact when the Project causes a change from LOS D to LOS E or F, or the Project causes an increase in delay of 2% or more at an intersection operating LOS E or F. 7.2 Traffic Impact Analysis Scenarios The following scenarios are those for which LOS calculations have been performed: A. Existing traffic; B. Existing plus Project conditions; C. Existing plus Project conditions plus mitigation (as required), D. Existing traffic plus ambient growth to the year the project will be completed plus cumulative project traffic; E. Traffic in (D) plus proposed Project traffic; F. Traffic in (E) plus mitigation (as required); G. Long -Term (Year 2034) Future Traffic Conditions; H. Traffic in (G) plus proposed Project traffic; and I. Traffic in (H) plus mitigation (as required).

These state-controlled locations include the following two study intersections: 4. Brea Canyon Road at SR -60 WB Ramps 5. Golden Spring Drive at SR -60 EB Ramps Caltrans "endeavors to maintain a target LOS at the transition between LOS "C" and LOS "D" on State highway facilities"; it does not require that LOS "D" (shall) be maintained. However, Caltrans acknowledges that this may not always be feasible and recommends that the lead agency consult with Caltrans to determine the appropriate target LOS. According to City of Diamond Bar, LOS D is the minimum acceptable condition that should be maintained during the morning and evening peak commute hours on all City intersections. 9.1 Highway Capacity Manual (HCM) Method of Analysis (Signalized Intersections) Based on the HCM operations method of analysis, level of service for signalized intersections is defined in terms of control delay, which is a measure of driver discomfort, frustration, fuel consumption, and lost travel time. The delay experienced by a motorist is made up of a number of factors that relate to control, geometries, traffic, and incidents. Total delay is the difference between the travel time actually experienced and the reference travel time that would result during ideal conditions: in the absence of traffic control, in the absence of geometric delay, in the absence of any incidents, and when there are no other vehicles on the road. In Chapter 16 of the HCM, only the portion of total delay attributed to the control facility is quantified. This delay is called control delay. Control delay includes initial deceleration delay, queue move -up time, stopped delay, and final acceleration delay. In contrast, in previous versions of the HCM (1994 and earlier), delay included only stopped delay. Specifically, LOS criteria for traffic signals are stated in terms of the average control delay per vehicle. The six qualitative categories of Level of Service that have been defined along with the corresponding HCM control delay value range for signalized intersections are shown in Table 9-1. 9.2 Existing Plus Project Traffic Conditions Table 9-2 summarizes the peak hour level of service results at the two state-controlled study intersections within the study area for Existing plus Project traffic conditions based on the HCM method of analysis. A review of this table indicates that both state-controlled study intersections currently operate at an acceptable LOS during the AM and PM peak hours. Further, a review of Table 9-2 indicates that traffic associated with the proposed Project will not significantly impact Brea Canyon Road at SR -60 WB Ramps and Golden Springs Drive at SR -60 EB Ramps as both are forecast to continue to operate at an acceptable LOS with the addition of Project generated traffic to existing traffic.

TABLE 9.1 LEVEL OF SERVICE CRITERIA FOR SIGNALIZED INTERSECTIONS (HCM METHODOLOGy)14 Level of Service (LOS) Control Delay Per Vehicle (seconds /vehicle) Level of Service Description This level of service occurs when progression is extremely favorable and most vehicles arrive A < 10.0 during the green phase. Most vehicles do not stop at all. Short cycle lengths may also contribute to low delay. This level generally occurs with good B > 10.0 and < 20.0 progression, short cycle lengths, or both. More — vehicles stop than with LOS A, causing higher levels of average delay. Average traffic delays. These higher delays may result from fair progression, longer cycle lengths, or both. Individual cycle failures may C > 20.0 and < 35.0 begin to appear at this level. The number of vehicles stopping is significant at this level, though many still pass through the intersection without stopping. Long traffic delays. At level D, the influence of congestion becomes more noticeable. Longer delays may result from some D > 35.0 and L 55.0 combination of unfavorable progression, long — cycle lengths, or high vle ratios. Many vehicles stop, and the proportion of vehicles not stopping declines. Individual cycle failures are noticeable. Very long traffic delays. This level is considered by many agencies (i.e. SANBAG) to be the limit of acceptable delay. These high E > 55.0 and < 80.0 delay values generally indicate poor progression, long cycle lengths, and high v/c ratios. Individual cycle failures are frequent occurrences. Severe congestion. This level, considered to be unacceptable to most drivers, often occurs with over saturation, that is, when arrival flow rates F > 80.0 exceed the capacity of the intersection. It may also occur at high v/c ratios below 1.0 with many individual cycle failures. Poor progression and long cycle lengths may also be major contributing factors to such delay levels. 14 Soume: Higlnvcry Cal acitydLanucrl2000, Chapter l6 (signalized Intersections), LINscott, LAw & GREENSPAN, engineers 27 LLG Ref. 2 -12 -3332 - Brea Canyon Business Center Project, Diamond Ba,' s¢auo:^ 1 zs32 - Irrn m<a,.,. c -ma om.,d n.mRzlnrznl;l, . ae, TABLE 9.2 YEAR 2012 PEAK HOUR INTERSECTION CAPACITY ANALYSIS — CALTRANS's 15 Bald ICUILOS values indicate adverse service levels based on City LOS standards.

It should be noted that given the current tenant mix reflects "business park -type" uses, the existing driveway volumes have been forecasted using ITE Land Use Code 770: Business Park trips rates. As noted earlier, the existing 20,571 SF industrial building contains eight (8) suites ranging in size from approximately 1,400 SF to 3,500 SF that is now occupied by a Carpet Wholesaler, CPA firm and Accounting Office, Structural Engineering Firm, Ethnic Education, Medical Equipment, Textile Wholesaler, Engineering and a Vacant Unit. According to the applicant, the tenant mix or uses are not expected to vary from what is now allowed under the site's current zoning. To provide a conservative assessment, the existing building is assumed to be fully occupied. Appendix D presents the ITE trip generation rates for a business park. Table 10-1 summarizes the intersection operations at the project driveway along Washington Street under near-term (Year 2014) and long-term (Year 2034) traffic conditions at completion and full occupancy of the proposed Project. The operations analysis for the project driveway is based on the Highway Capacity Manual 2000 (HCM 2000) methodology. Review of Table 9-1 shows that the proposed project driveway along Washington Street is forecast to operate at acceptable LOS A or better during the AM and PM peak hours for near -tern (Year 2014) and long-term (Year 2034) traffic conditions. In addition, due to the relatively low level of volume along Washington Street the project driveway is expected to have a maximum queue of one (1) vehicle both entering and exiting the site. As such, project access will be adequate. Motorists entering and exiting the Project site will be able to do so comfortably, safely, and without undue congestion. Appendix B presents Year 2014 and Year 2034 level of service calculation worksheets at the project driveway.

Leisch & Associates, and AnfoTURN for AutoCAD computer software that simulates turning maneuvers for various types of vehicles. The internal circulation layout for the Project has been reviewed and is adequate to accommodate service/delivery trucks, trash trucks (SU -30) and fire trucks (Platform 87ft) that would service the proposed site. Figures 10- 1, 10-2, 10-3 and 10-4 illustrate the turning movements for a small delivery/trash truck and a fire truck, respectively. An evaluation of the truck turning requirements of full-sized (WB -40 and W13-50) trucks indicates that accessing the site and circulating throughout the entire property would be difficult unless modifications to the parking layout of the industrial building were made (which could result in a loss of parking), the driveway was modified to provide a 40 -foot to 50 -foot "curb -return" and the existing median nose on Washington Street was shorted by up to 15 -feet. However, given the existing or future tenants of the industrial building are only likely to receive deliveries via small trucks (SU -30) similar to the proposed Project, the need to accommodate the turning requirement of full-sized (WB - 40 or W13-50) truck is not necessary and hence site modifications would not be required. To ensure adequate truck access and circulation is maintained and vehicular conflicts are minimized, it is recommended that access for full-sized (WB -40 or larger) trucks be restricted/prohibited. It recommended that the project applicant adopt this restriction in owner/tenant Conditions, Covenants & Restrictions (CC&R). The CC&R prohibition will be applied to all tenants of the existing building and proposed Project.

These capacity improvements involve roadway widening and/or re - striping to reconfigure (add lanes) to specific approaches of a key intersection. The identified improvements are expected to: mitigate the impact of area -wide deficiencies, and/or improve Levels of Service to an acceptable range. 11.1 Year 2012 Existing Plus Project Recommended Improvements The results of the intersection capacity analysis presented previously in Table 8-1 shows that the proposed Project will not significantly impact any of the five key study intersections under the "Existing Plus Project" traffic scenario. Given that there are no significant project impacts, no improvements are required under this traffic scenario. 11.2 Year 2014 Plus Project Traffic Conditions The results of the intersection capacity analyses presented previously in Table 8-2 shows that the proposed Project will not significantly impact any of the five key study intersections under the "Year 2014 Plus Project' traffic scenario.

The CMP for Los Angeles County requires that the traffic impact of individual development projects of potential regional significance be analyzed. A specific system of arterial roadways plus all freeways comprise the CMP system. 12.1 Traffic Impact Review As required by the current Congestion Management Program for Los Angeles County, a review has been made of designated monitoring locations on the CMP highway system for potential impact analysis. Per CMP TIA criteria, the geographic area examined in the TIA must include the following, at a minimum: • All CMP arterial monitoring intersections, including freeway on and off -ramp intersections, where the project will add 50 or more trips during either the AM or PM weekday peak hours. • Mainline freeway -monitoring stations where the project will add 150 or more trips, in either direction, during the AM or PM weekday peak hours. 12.1.1 Freeways The CMP freeway mainline monitoring stations in the vicinity of the study area are as follows: CMP Station No. 1031: SR -60 at Brea Canyon Road CMP Station No. 1032: SR -60 east of SR -57 The proposed project will not add 150 or more trips (in either direction) during the weekday AM and PM peak hours at CMP mainline freeway monitoring locations as stated in the CMP manual as the threshold for a traffic impact assessment. Therefore a CMP freeway traffic impact analysis is not required. 12.1.2 Intersections The CMP arterial intersection in the vicinity of the study area includes the intersection of Diamond Bar Boulevard at Grand Avenue. As stated earlier, the CMP guidelines require that arterial monitoring intersection locations must be examined if the proposed project will add 50 or more trips during either the AM or PM weekday peak hours (of adjacent street traffic) at CMP monitoring intersections. Based on the proposed project's trip generation potential, trip- distribution and trip assignment, the added AM and PM peak hour project generated trips to the adjacent street system does not require a CMP analysis.

The proposed Project includes the development of a two-story building consisting of 18,351 square -feet (SF) of office use and 3,443 SF of medical office use for a total of 21,794 SE Access to the subject property is now provided via a "full access driveway on Washington Street. The site is currently developed with a surface parking lot and is located adjacent to a 20,571 SF industrial building with surface parking. • Stur13P Scope —The following intersections were selected for detailed peak hour level of service analyses under Existing (Year 2012) Traffic Conditions without and with Project Traffic, Year 2014 Cumulative Traffic Conditions without and with Project Traffic, and Year 2034 Cumulative Traffic Conditions without and with Project Traffic: 1. Brea Canyon Road at Currier Road 2. Brea Canyon Road at Washington Street 3, Brea Canyon Road at Lycoming Street 4. Brea Canyon Road at SR -60 WB Ramps 5. Golden Springs Drive at SR -EB Ramps The analysis is focused on assessing potential traffic impacts during the morning and evening commute peak hours (between 7:00-9:00 AM, and 4:00-6:00 PM) on a typical weekday. Please note that the study locations were identified using the City's "16 trip threshold criteria". Level of Service (IIS) Standards and Significant ingmet Criteria - Impacts to local and regional transportation systems are considered significant if For Signalized intersections: ❑ the ICU value under "with project" conditions is 0.91 or greater (LOSE or F), antic ❑ the ICU increase attributable to the project is 0.02 or greater For Unsignalized Intersections: Based on the HCM/LOS method of analysis, this report identifies a significant traffic impact when the Project causes a change from LOS D to LOS E or F, or the Project causes an increase in delay of 2% or more at an intersection operating LOS E or F. • Existing Traffte Conditions — All of the five key intersections currently operate at satisfactory levels of service (i.e., LOS D or better) during the AM and PM peak hours. Project 'Trip Generation — On a "typical" weekday, the proposed Project is forecast to generate 326 daily trips, with 37 trips (32 inbound, 5 outbound) produced in the AM peak hour and 39 trips (8 inbound, 31 outbound) produced in the PM peak hour on a "typical" weekday.

These cumulative projects are expected to generate approximately 87,104 daily trips, with 6,356 trips (5,003 inbound, 1,353 outbound) anticipated during the AM peak hour and 8,891 trips (2,990 inbound, 5,901 outbound) produced during the PM peak hour. All of the eight cumulative projects are anticipated to be operational sometime after near-term year 2014 and before long-term Year 2034. Year 2012 Existing Traffic Cond ifions Plus Project— The proposed Project will not significantly impact any of the five key study intersections, when compared to the LOS standards and significant impact criteria specified in this report. The five key study intersections currently operate and are forecast to continue to operate at an acceptable service level during the AM and PM peak hours with the addition of Project generated traffic to existing traffic. Year 2014 Cumulative Traffic Conditions Plus Project — The proposed Project will not significantly impact any of the five key study intersections, when compared to the LOS standards and significant impact criteria specified in this report. The five key study intersections currently operate and are forecast to continue to operate at an acceptable service level during the AM and PM peak hours with the addition of Project generated traffic in Year 2014. Year 2034 Cumulative Traffic Conditions Plus Project — The proposed Project will not significantly impact any of the five key study intersections, when compared to the LOS standards and significant impact criteria specified in this report. The five key study intersections currently operate and are forecast to continue to operate at an acceptable service level during the AM and PM peak hours with the addition of Project generated traffic in Year 2034. State of California (Caltrans) Methodology — The results of the intersections capacity analysis using the State of California (Caltrans) Methodology indicates that traffic associated with the proposed Project will not significantly impact either Brea Canyon Road at SR -60 WB Ramps or Golden Springs Drive at SR -60 EB Ramps when compared to the LOS standards and significant impact criteria specified in this report. Both state-controlled study intersections are forecast to continue to operate at an acceptable LOS with the addition of project generated traffic to existing traffic and under Year 2014 and Year 2034 Cumulative Plus Proj ect Traffic Conditions. • Site Access and Internal Circulation Evaluation —The site access and internal circulation layout for the Project has been reviewed and is adequate to accommodate service/delivery trucks, trash trucks and fire trucks that would service the proposed site. Full-sized WB -40 and WB -50 trucks have difficulties accessing the site and circulating the property. Therefore, the project is proposing that CC& R prohibition be applied to all tenants that take access from the project driveway. This prohibition would only allow access by SU -30 trucks and smaller. CMP Compliance Assessment: The proposed Project will not have an impact on the Los Angeles County Congestion Management Program roadway network.

Items for consideration are listed on the attached agenda. I am employed by the City of Diamond Bar. On June 20, 2013, a copy of the agenda of the Regular Meeting of the Diamond Bar Planning Commission was posted at the following locations: South Coast Quality Management District Auditorium 21865 East Copley Drive Diamond Bar, CA 91765 Diamond Bar Library 21800 Copley Drive Diamond Bar, CA 91765 Heritage Park 2900 Brea Canyon Road Diamond Bar, CA 91765 I declare under penalty of perjury that the foregoing is true and correct. Executed on June 20, 2013, at Diamond Bar, California. Stella Marquez Community Development Department CDAzstelIaW idavitposting.doe Stella Marquez From: Greg Gubman Sent: Monday, June 24, 2013 12:21 PM To: James DeStefano Cc: Stella Marquez Subject: FW: Planning Commission Meeting Jim, The PC agenda had a clerical error, stating that the meeting was scheduled for June 23rd (yesterday). City Attorney recommends reposting the agenda as spelled out below. If you have any concerns, please contact me as soon as possible. Thanks. Greg Gubman, AICP I Community Development Director City of Diamond Bar I Community Development Department 21810 Copley Drive I Diamond Bar, CA 91765 909.839.7031 1 909.861.3117 (f) www. DiamondBarCa.Gov From: David A. DeBerry [mailto:DDeBerry@wss-law.com] Sent: Monday, June 24, 2013 12:03 PM To: Greg Gubman Cc: James H. Eggart Subject: Planning Commission Meeting Greg, As a follow up to our conversation concerning the PC agenda being posted with the wrong date, I suggest the following: 1. Post a corrected notice with the right date immediately and make sure it is correct on City's website, which it appears to be. 2. Post a notice of a special meeting. Since special meetings only require 24 hours notice, then the City will have complied with that posting requirement and this should cure any Brown Act violation, especially since we understand that the notices of the public hearing were correct as published in the newspaper. To comply, written notice must be sent to each member of the Planning Commission and to each local newspaper of general circulation by whatever method is necessary to make sure it gets to the members and the newspaper at least 24 hours prior to the meeting. My recommendation is to change out the current posted agenda, with an agenda that has the right date. The title of the agenda would be "Corrected Date for Regular Meeting of the Planning Commission and Notice of Special Meeting." Somewhere on that first page it should state something to the effect that the previously posted agenda incorrectly noticed the date of the regular meeting as June 23rd. This agenda corrects this clerical error. The corrected agenda should then be sent to the Planning Commission and the newspaper at least 24 hours before the meeting as noted above. We did not find anything which would preclude the City from calling a special meeting and suggest this as a belt and suspenders approach to complying with the Brown Act and to ensure the Planning Commission's actions will not be voided should they be challenged. If the City substantially complies with the Brown Act, which we believe it will by following these recommendations, a court generally will not void the City's actions. For someone to prevail in an action challenging the Planning Commission's decision, they would have to bring a challenge within 90 days of the decision, show they did not have actual notice and show they were prejudice by the erroneous posting of the date. You were going to discuss with the City Manager, as he should make the final call on this. The Planning Commission should be made fully aware of this issue as well as they are the ones who would be charged with a Brown Act violation. Let me know if you have any questions. ' WJDavid A.
