VAN NORT, CITY MANAGER FROM: RONALD L. KRANZER, CITY ENGINEER SUBJECT: AWARD OF BID - TRAFFIC SIGNAL EQUIPMENT FOR GRAND AVENUE AT LONGVIEW DRIVE, SHOTGUN LANE AND SUMMITRIDGE DRIVE Formal bids were received March 27, 1990 from one contractor. The bid schedule called for 21' signal pole and mast arm combinations for the signal improvements on Grand Avenue at Longview Drive, Shotgun Lane and Summitridge Drive. The project generally consists of supplying traffic signal poles, mast arms and hardware for future installations. The average delivery time for signal poles and mast arms is 14 to 16 weeks after issuance of a purchase order. In order to expedite the installation of signals, staff recommends ordering the poles in advance of final approval of plans and specs. This process reduces overall construction times by as much as 10 weeks. The bid received for this project (see attached Bid Summary Form) was from Triad Sales (a division of Union Metal Corp.) for $11,667.00. Although there was only one bid, staff is confident we have received a good bid. Triad has consistently been the low bidder on signal poles in every similar project for Diamond Bar and Walnut. Staff can find no reason not to award this project to Triad Sales.

The Sanitation Districts of Los Angeles County. (LACSD) operate five water reclamation plants (WRP) which produce reclaimed water suitable for numerous forms of reuse. Two of the plants are in relatively close proximity to the City of Diamond Bar (City), the Pomona WRP immediately north of the City limits, and the San Jose WRP at the intersection of the San Gabriel River Freeway and the Pomona Freeway. Reclaimed water is presently used for irrigation in the City at the following locations: _ Diamond Bar Golf Course for turf irrigation and ornamental lake supply, the Gateway Corporate Center for greenbelt and slope irrigation, and by Caltrans for a portion of the freeway landscape within the City. The reclaimed water originates at the Pomona WRP, and is conveyed to the City through the reclaimed water transmission and distribution systems of the City of Pomona (Pomona) and the Walnut Valley Water District (WVWD). - The current level of water reuse at these three City locations is 0.36 million gallons per day (mgd) on an average annual basis, with peak daily deliveries approaching 1.0 mgd. The City desired to take a proactive step to expand the present water reuse practice in _ the City, and on September 5, 1989 selected Boyle Engineering Corporation (Boyle) to prepare this feasibility study. 2-1 CHAPTER 3 RECLAIMED WATER DEMANDS The current and projected demand for reclaimed water in the City is summarized in this chapter through delineation of reuse sites, a market survey, and calculation of demand rates. REUSE SITES DELINEATION The first step in analyzing the potential demand for reclaimed water is to delineate reuse sites and identify potential users. In surveying the City and its surroundings, the following sites were identified on the basis of acreage and are grouped according to the following categories: • Recreational Irrigation _ School Site Irrigation Residential Irrigation • Greenbelt Irrigation Other Potential Reuse These sites are delineated on Figure 3-1 and described below. Recreational Irri ag tion Recreational irrigation demand in and adjacent to the City includes: existing and proposed golf courses, existing and proposed parks, the Little League field and Diamond Bar Country Estates. Golf Courses. The Diamond Bar Golf Course is an existing public course owned by the County of Los Angeles and situated within the City's limits. Reclaimed water has been used to irrigate the course since 1981. There are plans for the construction of two 18 -hole golf courses on what is currently the Firestone Boy Scout Reservation, according to the Southern California Golf Association (SCGA). In addition to the golf course, a clubhouse and the SCGA regional headquarters are being planned for this area. 3-1 01 6 r*jplp� v mompow a" HM*M P" Otani A= AW POV" FIAM un- "I wpm 9FAW kn_ cm :' :p • ,:- :*�- Parks. Eight parks are currently maintained by the City's Park and Recreation Department. In addition, two sites have been set aside for future park development. According to the City's Community General Plan, however, the City is deficient in acres of park land. To help rectify this situation, a Park Dedication Ordinance was adopted and requires that subdividers provide park space to serve new developments. Based on this requirement, future parks, although not specifically identified at this time, will be considered when assessing potential demands. Little League Field. The Little League field is situated along the northern boundary of the City, and consists of a 16 -acre area that could be irrigated with reclaimed water. Diamond Bar Country Estates. The Diamond Bar Country Estates Association maintains the Country Park - one hundred thirty three acres of land in its natural state, an equestrian arena, tennis courts, and two landscaped entrances. The community and its facilities lie in the southeast corner of the City. School Sites Irrigation Diamond Bar is served by two school districts: Walnut Unified School District, which covers the northern area of the City, and Pomona Unified School District which covers the southern area. There are currently eight elementary schools, two junior high _ schools, and one high school within the City's limits. Due to the influx of school age children, four new elementary schools and one high school have been proposed. These future sites will be considered in the assessment of potential demands. For purposes of this study only, it has been assumed by the City that the future high school could be located on the Tres Hermanos Ranch portion of the City. Residential Irrigation There are three areas which are being considered as sites for new residential development, in or adjacent to the City. Consideration could be given to including dual water distribution systems in these developments, which are described as follows: 1) One hundred eighteen lots within the Country Estates, with an average lot size of over an acre. 3-2 2) An area currently outside of the City's limits which extends from the City's southern border to the Orange County line. The approximate gross acreage of this area is 835 acres. 3) The pocket of land bordering the City's limits, west of Brea Canyon Cutoff Road. Greenbelt Irrigation Potential greenbelt irrigation in the City includes areas within the existing Landscaped Maintenance Districts and freeway irrigation within the Caltrans right-of-way. Landscaped Maintenance Districts. The City currently has three landscaped maintenance districts (M.D.). M.D. #38 includes landscaped areas along the City's major arterials: Diamond Bar Boulevard, Grand Avenue, Golden Springs Drive, Pathfinder Road, Brea Canyon Road, Sunset Crossing Road and Temple Avenue. M.D. #39 is located in the center portion of the City along its eastern border, and M.D. #41 covers an area in the southwest corner of the City. Freeway Right -of -Way. Caltrans currently maintains landscaped areas within it's right-of-way along the 57 and 60 freeways. A portion of this greenbelt is already being served by a reclaimed water system, but reuse levels could increase significantly. Other Potential Reuse Other potential applications of reclaimed water use in Diamond Bar have been investigated, including: 1) Irrigation of a potential post secondary education campus _ that could be located in the City; 2) water used for fire control, and 3) toilet flushing in future industrial park high-rise construction. Potential Campus Irrigation. The California Post secondary Education Commission and other State of California education entities are evaluating several potential sites throughout the State for future post secondary education campuses, including a site in the City. However, initial planning has not indicated that the City site will be pursued for detailed investigation, and therefore is not considered for reuse potential at this time. 3-3 Fire Control. The Los Angeles County Fire Department was questioned about the use of reclaimed water for fire control. It was determined that since the risk of fire is low in this area, use of reclaimed water would not significantly diminish the demand for potable water. Also, it appeared to the Fire Department that the City has an equal fire risk throughout; therefore, it was not possible to concentrate the demand by focusing on a particular area. Consequently, the potential reclaimed water demands for this specific use were not further explored. Use of reclaimed water for slope irrigation (landscaped maintenance districts) would indirectly result in water reuse for fire protection. High-rise Toilet Flushing. One cf the more state-of-the-art applications for reclaimed water use is that of toilet -flushing in high-rise buildings. Although the California Department of Health Services (CDHS) has not yet issued final approval of such application, two high-rise buildings in the City of Irvine have been constructed with separate systems for toilet flushing with reclaimed water, and actual operation is expected soon. Future buildings in the Gateway Corporate Center and the industrial park on Grand Avenue are candidates for high-rise toilet flushing systems fed by reclaimed water, and will be considered in this study. MARKET SURVEY With this preliminary identification of potential water reuse sites and a review of records from the water purveyor, eight potential users were identified for the market survey. In general, if a customer's usage was recorded to be more than 500 ccf/month, then they were considered to be potential users. On this basis, a market survey was performed to gage interest of these potential users in the use of reclaimed water for landscape irrigation. The following summarizes the finding of the preliminary market survey. Schools The Walnut Unified School District currently has school sites outside of the City limits that are served by a reclaimed water system. The remaining schools are all candidates for reclaimed water service. A representative from the maintenance department attributed certain costs to the quality of reclaimed water, but still noted the overall savings. The 3-4 Pomona Unified School District has had no prior experience with such a system; however, they expressed an interest in water reuse for irrigation of their athletic fields and landscaped areas. Parks Although the City of Diamond Bar is interested in reclaimed water for their parks, Los Angeles County Department of Public Works (LACDPW) was surveyed because of their past experience in maintaining these parks. The LACDPW Park Architect initially expressed concern over the effects of reclaimed water on plant growth, but stated an interest if there were to be dollar savings resulting from the conversion. Diamond Bar Country Estates Association The Association expressed an immediate interest in a reclaimed water system. They listed a trail, their community entrances and show arena as potential sites. Additional land is slated for development, which would increase their current water usage for irrigation. Diamond Bar Golf Course In addition to potential users, an existing user, the Diamond Bar Golf course, was contacted to discuss their experience with reclaimed water service. The golf course is owned by Los Angeles County Department of Parks and Recreation, but the land is leased to Golf Corporation. Reclaimed water is delivered to a lake within the site. A booster pump draws water from this lake and feeds it to the sprinkler system. In general, the system has worked well. They cited the benefits to plant growth, service reliability, and did not have any reports of disposal or runoff problems, or difficulty in maintaining separate potable and reclaimed water systems. Caltrans M1 Although only small quantities of reclaimed water have been used for freeway area irrigation in various parts of Southern California, Caltrans is now willing to pursue expanded reuse within it's rights-of-way. Recent legislation has been enacted to provide a stimulus to such programs. It is expected that Caltrans will be a willing participant in an expanded reuse program in the City. Firestone Golf Course Discussions have been held with representatives of SCCA regarding the potential for a reclaimed water service to the proposed golf course development planned for the Firestone Boy Scout Reservation. Although SCGA is hopeful that untreated imported water from the MWDSC Yorba Linda Feeder can be used for this purpose, they would consider an alternative reclaimed water system. RECLAIMED WATER DEMANDS Having established the potential areas of water reuse, it is necessary to quantify this _ usage. The assumption throughout is that potential users will want to maximize the use of reclaimed water wherever possible. The approach taken in estimating the demands was to determine the current potable water usage, and use this as a basis for: 1) estimating the portions that could be converted to reclaimed water usage, and 2) projecting future demands. Data was collected from various sources to develop potential water reuse demands. Walnut Valley Water District provided Customer History Reports which record domestic water usage per billing period for those customers identified as potential users. WVWD also provided Reclaimed Water Reports which record monthly usage rates and irrigable acreage for sites currently being served by WVWD's reclaimed water system. The City provided construction plans of its parks. A survey of these plans resulted in an estimate of irrigable acreage and a corresponding demand rate. Upon developing the potential demands, the corresponding reuse sites were classified in the following manner: 1. Sites within the City limits which are currently being served by a reclaimed water -- distribution system. 3-6 2. Existing sites within the City's limits to be served by an expansion of the system. 3. Future sites within the City's limits to be served by an expansion of the system. 4. Future sites outside of the City to be served by an expansion of the system. The results of this analysis are presented in Table 3-1 - Summary of Potential Reclaimed _ Water Demands. Table 3-2 is an expansion of the information presented in Table 3-1, and lists the sites which are included in the four potential reuse categories described above, along with the corresponding demand estimate. Following Table 3-2 is a descriptive analysis of the data which resulted in the tabulation of potential reclaimed water demands. The average monthly domestic water usage was calculated from the WVWD Customer History Reports which record billing information from the past two years. The average monthly reclaimed water demand was estimated to be equal to the average monthly _ domestic water usage minus a rate of 15 gallons/student/day for the school year (9 months). The ration of reclaimed water demand to domestic water usage was found to be in keeping with ratio of rates established in WVWD's report for a similar application. A peaking factor of 10 was used to calculate peak day requirements. This factor was derived from the ratio between peak month to average month water demands (monthly peaking factor of 4), and from an assumed irrigation rate of 3 times/week. A proposed high school and three elementary schools were included in the tabulation of potential reclaimed water demands. The demands for the high school were assumed to be the same as for the existing Diamond Bar High School, and those for the elementary schools, the same as the average of the existing schools. 3-7 TABLE 3-1.

An additional 25 acres of park land are undeveloped. Of this total of 140 acres, the City's Community General Plan dictates that 58 acres will remain in their natural state; therefore, 82 acres of existing park land are either developed or will be developed in the future. Assuming that 80 percent of developed land is irrigable, then 65 acres of land set aside for parks is irrigable. Of this 65 acres, 40 are in existence (as established by a quantity takeoff of the park plans). The remaining twenty five irrigable acres of park land are assumed to be developed in the future. The Community General Plan also projects a need for an additional 65 acres of park land if the City develops to capacity. Using the ratio of irrigable acreage to total acreage for land that has been set aside for parks, and applying this to the projected acreage for future parks, this results in an additional 30 irrigable acres of future park. In conclusion, the total estimate of irrigable acreage for future parks is 55 acres. The average demand was calculated using the estimated irrigable acreage and a factor of 2.14 acre feet per acre per year (ft/yr). This factor is an average calculated from data supplied in WVWD's Reclaimed Water Usage Monitoring Reports for parks currently being served by a reclaimed water system. The peak day demand was calculated using a peaking factor of 2.64, a number which has been established in the "Orange and Los Angeles Counties Water Reuse Study" to be representative in this type of application. Aside from the existing and projected park requirements, a future park site was located in the eastern fringe of the City, and is assumed to be a regional park of 50 irrigable _ acres. Demands for this park were estimated using the same factors as described above. M Landscaped Maintenance Districts The total average monthly water use was calculated as an average of the monthly rates recorded in WVWD's Customer History Reports. The reclaimed water demand is estimated to be equal to the average domestic water usage, assuming that all of the. water usage reported is for irrigation purposes. A peaking factor of 2.64 was used to calculate peak day requirements. Caltrans - A procedure similar to that used to calculate the Maintenance District demands was used to estimate Caltrans potential usage. Other The reclaimed water demand for the Little League Field and Diamond Bar Country Estates was estimated on the basis that the domestic water reported for these users by WVWD is principally for irrigation purposes. Golf Course _ Based on information supplied by the Southern California Golf Association, an average demand of 700 afy. was assumed, since the proposed course will be of "Scottish" design with reduced irrigation requirements. Residential Irriaation For the Country Estates Development, tract plans were used to estimate gross acreage less acreage remaining in a natural state (approximately 30%). A factor of 500 gallons/acre/day was applied to the resulting acreage for an estimate of the potential demand, based on dual distribution experience of Las Virgenes Municipal Water District. Assuming that the development of the potential area south of the City would be similar to that planned for Diamond Bar, it was estimated that 75 percent of the land will be developed, of which 90 percent will be residential use. The same factor of 500 gallons/acre/day was applied for residential irrigation. 3-9 For the potential west development, the total acreage was multiplied by the above water reuse factor. High-rise Toilet Flushing The gross acreage set aside for commercial and/or industrial park development was multiplied by 40 percent, resulting in a square footage estimate of the building pads. It was assumed that an average building would be three stories high. A factor of 30 gallons per day per 200 square feet was applied, resulting in an estimate of the potential demand for toilet flushing in future City high-rise buildings. 3-10 TABLE 3-2.

The following sources have been analyzed: 1) Pomona W. R. P. (LACSD) 2) San Jose Creek W.R.P. (LACSD) - 3) Potential Diamond Bar W.R.P. (City) POMONA W.R.P. The Pomona W.R.P. operated by LACSD is the source of supply for current water reuse in the City. The plant has a rated capacity of 10 mgd, and an expansion to a total of 15 mgd is planned to be completed in 1991. By long term agreement, the City of Pomona has a right to utilize up to the full plant flow, which it does except during brief winter periods. In addition to reclaimed water use in the City of Pomona for landscape and - industrial uses (two paper mills), extensive water reuse occurs at Cal Poly - Pomona University. 2000 acre-feet/year is utilized by the WVWD, including current use in Diamond Bar. Discussions with LACSD personnel indicate that no excess reclaimed water supply is presently available from the Pomona WRP, and that the additional 5 mgd available after the expansion will probably be utilized by existing customers, including Cal Poly - Pomona, Golden Gate Paper Company, WVWD, and LACSD itself for use at the Spadra Landfill. Discussions with the City of Pomona Water Department confirm that no continuous, supplemental reclaimed water supply is available for another entity either now or following the planned Pomona WRP expansion. A separate analysis has been conducted to determine if it might be feasible to supply reclaimed water to a current customer of the Pomona WRP/City of Pomona delivery system, e.g. Cal Poly University, Pomona, from an alternative supply location, e.g. an extension of the existing San Jose Creek WRP/City of Industry delivery system. If such - a program were cost-effective, it is conceivable that some reserve capacity in the 4-1 IV. FUTURE SITES OUTSIDE OF CITY TO BE SERVED BY EXPANSION OF SYSTEM A.

Cost estimates have been prepared for a conceptual pumping and transmission system from the present terminus of the Industry system in Industry Hills to the Cal Poly - Pomona campus. Unit costs of these supply facilities are approximately 40 percent greater than the projected supply costs from San Jose Creek WRP to Diamond Bar. Also, additional conveyance facilities would have to be built from the Pomona WRP to the Diamond Bar system. It is therefore concluded that this conceptual idea is not cost- effective. It is concluded that the Pomona WRP is not a viable long term source of reclaimed water for the City. SAN JOSE CREEK W.R.P. The San Jose Creek W.R.P. presently treats 62.5 mgd of wastewater, and the plant is programmed for expansion to 100 mgd, slated for completion in 1992. Flows are expected to increase to approximately 85 mgd following the expansion. Even considering other water reuse commitments, e.g. downstream groundwater recharge, at least 30 mgd is available for irrigation and other reuse by other agencies, with over 60 mgd available for such use after the proposed expansion. Current reuse levels from the San Jose Creek WRP are low, approximating 1.5 mgd for use at the Industry Hills Conference Center, California Country Club, and a small nursery. Plans for additional use of reclaimed water from the San Jose Creek WRP are planned as follows: 1) Puente Hills Landfill (LACSD) - 3 mgd; 2) Rose Hills Cemetery - 1 mgd; 3) City of Industry - 2 mgd (includes 1 mgd requested by WVWD). The City of Industry (Industry) currently has an agreement with LACSD for use of up to a 4 mgd supply of San Jose Creek WRP reclaimed water, and is presently attempting to _ increase the contracted amount to 10 mgd. Discussions with both LACSD and Industry indicate a willingness to further increase contracted amounts to include projected water reuse by the City. 4-2 C.

Interconnection With WVWD The western portion of the WVWD reclaimed water system terminates near the Industry reclaimed water pipeline. There are two possible alignments for a proposed interconnection, as shown on Figure 4-1. However, there are technical difficulties associated with an interconnection. One difficulty is that both of the WVWD east -west pipelines contain pressure relief valves (PRV's). The PRV's effectively limit the water flow in the opposite direction needed to supply Diamond Bar. The second difficulty is related to the flow direction in the Fairway Drive pipeline. It appears the water also flows in the opposite direction when needed to supply Diamond Bar during the irrigation period. A substantial portion of the WVWD system would require engineering analysis and re -design to account for different operating pressures and flow directions should interconnection be attempted. The third difficulty is associated with the Colima Road/Golden Springs Drive pipeline. This 12 -inch diameter pipeline is not of sufficient capacity to efficiently transport the flows required by Diamond Bar. Separate Connection The technical problems associated with interconnection can be bypassed by a separate connection. A supply system is proposed to transport reclaimed water from the City of Industry system terminus to a location east of Brea Canyon Cutoff and Colima Roads. At that location, an intertie with the WVWD system would be made. Half of the flows would utilize the WVWD system, the remainder would flow in a proposed parallel pipeline to the existing WVWD terminus at the Diamond Bar Golf Course. Figure 4-2 shows a schematic of the proposed system. Booster stations would be required to convey the 4-3 i m r f 6m 1"" 111 reclaimed water to higher elevations. Two booster stations capable of increasing the HGL by approximately 245 feet (490 feet total) are anticipated. POTENTIAL DIAMOND BAR W.R.P. Another potential source of reclaimed water would result from the construction of a potential water reclamation plant within the City itself. It would be envisioned to divert sufficient wastewater flows from the trunk sewer system upstream of the connections to the LACSD interceptor system, to meet the reclaimed water needs of the City. The capacity of the Diamond Bar W.R.P. would be approximately 4 mgd initially, with ultimate - expansion to a total of approximately 6 mgd. Implementation of the potential Diamond Bar WRP project would involve extensive planning to address technical and environmental aspects of such a major project; would incorporate state-of-the-art treatment technology, including air emissions collection and scrubbing; and would necessitate a major financial commitment. It is estimated that the initial capital cost for such a facility would approximate $18,000,000, and including expansion costs to meet future reclaimed water demands, total capital costs would exceed $25,000,000. RECOMMENDED SOURCE OF SUPPLY Although the Pomona WRP would be the logical source of additional reclaimed water for the City, the supply is and will be constrained by existing reuse practice. The City could construct it's own reclamation plant, but capital costs would exceed $25 million. The San Jose Creek WRP has excess capacity for supplying the City's reclaimed water demand; supply costs to utilize this source, as will be described in Chapter 6, will approximate $5 million. It is therefore recommended that the City pursue a supplemental - reclaimed water supply from the LACSD San Jose Creek WRP. 4-4 CHAPTER 5 STORAGE ANALYSIS Storage facilities are beneficial to meet supply and reliability requirements of reclaimed water systems. By capturing daily reclaimed water supply peak flows during the non -irrigation period and conveying into storage, distribution of reclaimed water during periods of low supply can be made possible. Providing more than one maximum demand day of on-line storage is not economically _ justifiable. A one -day storage facility will adequately serve the irrigation system for both operational and emergency storage purposes. Instead of providing even greater emergency storage capacity with a larger reservoir, it is recommended that the storage facility design include a backup supply of potable water from WVWD. Such an emergency connection would provide a continuous standby water source for reclaimed water outages caused by potential wastewater facility noncompliance, equipment failure or insufficient supply. STORAGE REQUIREMENTS A storage reservoir is recommended for the ultimate system (Stage 2). A storage reservoir is not proposed for the initial Stage 1 construction, since the supply system can meet the initial peak hour demands. System reliability can be provided by varying the supply pump configurations. Provision of a reservoir in the Stage 2 system results in increased supply. By designing the supply system to continually provide reclaimed water at the rate of 5.7 mgd, the ultimate maximum day demand of 17 mgd can be met. The Stage 2 System flow rate is based on the supply system providing 5.7 mgd and the reservoir providing the remainder of the demand (11.3 mgd). Some level of storage should remain in the reservoir at the end of the irrigation cycle. This will provide a periodic turnover of stored reclaimed water. It has been assumed that this residual storage requirement is 10 percent of the total reservoir capacity. To provide a one -day maximum demand storage capacity plus 10 percent would require a storage facility of approximately 5 million gallons (MG). 5-1 STORAGE METHOD Since it is not desirable to remove nutrients from wastewater that will be reclaimed for irrigation, it becomes necessary to initiate control methods to prevent excessive algae growths that would occur in an open reservoir. Experience in using reclaimed water for irrigation has shown that a covered storage facility or enclosed concrete or steel tank, with a chlorine residual maintenance control station provides a means whereby proper water quality can be maintained. Algae growth would be prevented due to lack of sunlight, and the chlorine residual prevents slime formation not only in the reservoir, but also in the distribution system. RESERVOIR SITING A preliminary location of a storage reservoir was chosen based on two criteria, hydraulic performance and available land. Consideration was given to meeting the City's reclaimed water storage requirements by utilizing a portion of capacity in a regional covered, surface reservoir envisioned for potential construction by the Industry Urban Development Agency on it's property on the Tres Hermanos Ranch. However, implementation of this regional project would require extensive planning and involvement of several agencies, and is not recommended to meet the smaller storage requirements of the City at this time. Storage facilities are sited at an elevation which provide the least amount of pumping to refill the reservoir, and at the greatest elevation to provide gravity flow through the distribution system. The preliminary site is centrally located within the distribution system on a currently undeveloped parcel. It would be located at a higher elevation of the City which helps to maintain adequate system pressure one both sides of the ridgeline. Reservoir refill is accomplished with the proposed supply booster located at the Golf Course during the non -irrigation period. A 5 MG enclosed reservoir is proposed to be located at elevation 1240 in the general area as shown in Figure 5-1. It will provide for increased supply associated with the Stage 2 System. 5-2 »- r 1i r IMMPh i- 1r 1%'i�io1a' Ml CHAPTER 6 PROJECT DEVELOPMENT This chapter presents a description of the required reclaimed water supply system, staged construction of a distribution system, and facilities cost estimates. SUPPLY SYSTEM The recommended supply system identified in Chapter 4 is to pursue a supplemental reclaimed water supply from LACSD San Jose Creek WRP, and to accomplish the following: - 1. Obtain capacity rights in the industry pumping and transmission facilities between San Jose Creek WRP and Industry Hills. 2. Construct additional pumping and transmission facilities to connect with the WVWD system. 3. Construct parallel transmission facilities within the WVWD service area. Capacity Rights in Existing System Facilities It is expected that the City of Industry will require cost recovery for capacity rights related - to Diamond Bar capacity, in the existing pumping and transmission facilities constructed previously by Industry. City of Industry is currently conducting a study to determine the mechanism for assessing such charges; however, no data is forthcoming that can be utilized for this report. Boyle has determined an approximate current value of the capacity rights in the Industry system for ultimate City reclaimed water demands, based on an original cost - less depreciation approach, and a pro -rata hydraulic capacity analysis. This value is estimate to be $500,000. 6-1 Area Transmission System As indicated in Chapter 4, it will be necessary to construct additional facilities to convey reclaimed water from the terminus of the Industry transmission main, and paralleling the WVWD system to the Diamond Bar Golf Course. Required facilities include two booster stations, each 5.6 mgd peak capacity; 12,700 LF of 24 -inch pipeline; and 15,500 LF of 12 -inch pipeline. The total costs of these new facilities estimated at $4,995,000. DISTRIBUTION SYSTEM MODEL DESCRIPTION A computer model of the optimum distribution system was developed to assist in the evaluation. The primary step in developing the computer model is to establish a network of pipes and nodes. Network For this study, only 8 -inch and larger pipes were modeled. Nodes were utilized to represent points of intersection, changes in pipe diameters, or locations where supply or demands were applied to the system. Data for each node includes the ground elevation, associated average demand and coordinates utilized in plotting the system. Each pipe is described by the two connection nodes, a length, diameter, and roughness coefficient. The sources of reclaimed water to a system can be modeled in three different manners: as a fixed hydraulic grade line (HGL), a fixed flow input or as a pump operating on a pump characteristic curve. By simulating the source, the computer model will calculate the flow delivered to the system under a specified condition. Reservoirs "floating" on the system are generally modeled as a fixed HGL. D mAnda The reclaimed water requirements at the nodes are referred to as demands. Demands on the system can be entered as average or peak demands. Peak demands are subject to a peaking factor converting average day demands to the peak hour demand. Average demands can be used to represent supply flows which remain constant for the _ peak condition and therefore are not increased by the peaking factor. Demands on the system are represented as negative numbers. Positive flows represent water entering the system, such as from supply sources. — Boosters Booster pumps are utilized to increase the HGL, or water pressure, should service to an area fall below the minimum allowable level. Booster pumps are modeled by associating a pipe number with a pump curve containing several flow/head coordinates. Pressure Reduction Valves Pressure reduction valves (PRV) area utilized to decrease the HGL, or water pressure. In the model, a PRV is described as a short pipe with the downstream HGL fixed by an inputted value. ULTIMATE SYSTEM The ultimate reclaimed water system would result from construction of both Stage 1 and Stage 2 facilities. It provides reclaimed water to known sites and provides an added capacity for future requirements also identified in Chapter 3. Network A schematic of the Ultimate System is shown on Figure 6-1. The primary transmission pipelines are 20- and 18 -inch diameter, generally located along Grand Avenue and Diamond Bar Boulevard. Intermediate stage distribution pipelines are sized either as 12 - or 8 -inch diameter. 6-3 �tl ., 14, --.— r# Y JV if It` ._�;� '� .+ � its �- �' 4 ti�� N n'` �,��1�.. _•,,r 5 _ � s "OWO (►i' rte _ � r J11 �� ., ..,K�� ,-,� >,f�, -�o.:.. .. �^r..r yon .... w� ��i�• ��_ "�!�.�4c ��arM�,o„�1 ',�+"C i ��' �� "�'1' ��• '� � �. , ter+ ��1 p i=t5�+ '�� A' e4 `5"• C"` / '`�� 1 fix,, jl +t di r • ,Fi�°rl��.r� � � • � '� '�'� `app' � t�ir "!w � � C° � \ � `�� .ri" r All "tdt° '{..

This search is summarized on Figure 6-2, and indicates no major utility constraints, based on preliminary data. Alternative transmission pipeline construction adjacent to the 57 and 60 Freeways would result in greater total project costs. SUgp1V Reclaimed water enters the system at Node 2, which represents the supply intertie with the Walnut Valley Water District's reclaimed water system. Approximately 5.7 mgd is required at a constant rate from this supply source. During the non -irrigation period, water is pumped to the storage reservoir. Since the total demand cannot be met by the supply source, a storage reservoir must be constructed to provide the additional needed supply. Water flows from the reservoir at a rate of 11.3 mgd. The reservoir is modeled at Node 1000 with a fixed HGL of 1240 feet. The computer model determines the hydraulic balance of the network system and identifies the supply rate required from the reservoir. Demands The Ultimate System provides approximately 5.7 mgd on an average basis, and almost 17 MG delivery rate for the assumed 8 -hour irrigation period. Table 6-1 summarizes the nodes and their associated demands under ultimate conditions. Boosterr? Three booster stations are required to distribute the flows in the Ultimate System. Supply Boc) ter Station. Reclaimed water entering the system from the WVWD supply will need to be boosted. During the non -irrigation period, this booster will continue to receive incoming water and provide sufficient lift to fill the storage reservoir. During the irrigation period this booster conveys 4.1 mgd through a lift _ of 218 feet. During reservoir refill operations, it boosts 5.7 mgd approximately 323 feet.

Probable Proie Costs An opinion of probable project cost was prepared. Included in the probable cost opinion - administrative and are facilities for supply; distribution (including storage); engineering, vides for contingency. The probable cost opinion was based on published g construction estimating and comparison of previous projects. The probable cost opinion represents the engineer's judgement as a design professional, not a construction contractor or estimator, and are supplied for the general guidance of the City. With no control over the cost of labor and matrri 1, or omp ed l itive to bidding and market conditions, the accuracy of such cost opinions contractor bids or actual cost to the City cannot be guaranteed. The probable cost opinion for the Ultimate System is approximately 17.3 million dollars, and is delineated in detail on Table 6-2. 6-5 Opinions shown are in the approximate range of -20% to +30%. The opinions are based on planning concepts only and represent the Engineer's knowledge as a design professional. Actual construction costs, for example, can only be provided by a construction contractor based on construction INITIAL SYSTEM for the ultimate system, o Because of the significant level of project cost necessary consideration has been given to a staged construction Program in order to provide a partial distribution system at reduced cost.

Several of the following sources of funding and revenue could be pursued: 1 • State Water Resource Control Board (SWRCB) low-interest loans for reuse projects. 2. Metropolitan Water District of Southern California (MWDSC) L Program. ocal Projects 3. Bond Issues. 4. Certificate of Participation. 5. Redevelopment Agency funding. 6. Connection charges. 7• Reclaimed water sales. SWRCB LOW INTEREST LOANS The Clean Water and Water Reclamation Bond Law of 1988 (Chapter 47, Statutes of 1988, Proposition 83) provides $65 million for low interest loans, grants, and guarantees for local agency bonds to local public agencies to construct facilities necessary to eliminate water pollution and public health hazards. The SWRCB administers s the 7-1 Loans Of the $65 million, $30 million is available for loans up to 100 percent of the cost of the design and construction of eligible water reclamation and reuse projects. Eligible projects are those that are cost-effective when compared to the cost of alternative new freshwater supplies and for which no federal assistance is currently available. Costs of land for application of reclaimed water are not eligible. Multiple -purpose projects, such a as groundwater recharge projects which percolate both storm runoff and treated wastewater, are eligible in proportion to the costs allocated to water reclamation and reuse. The loan interest rate is 50 percent of the rate paid by the state on the most recent sale of general obligation bonds. Loans must be repaid within 20 years. It is the present policy of the SWRCB that loans should not exceed $5 million per project. Y Loan applications must be accomplished by a facilities planning report, which demonstrates cost-effectiveness as compared to other alternative new water supplies, environmental protection, technical feasibility, and the economic demand for reclaimed water. Priority is generally given to eligible projects for which facility planning is complete. Some funds are available from the Clean Water Bond Law of 1984 where repayment of principal and interest on loans is returned to make additional loans. Loans from this source must be repaid within 25 years and may not exceed $10 million per project. Grants Twenty-five million dollars is available for grants to small communities (public agencies, or isolated parts thereof, with a population of 3,500 persons or less) for construction of wastewater treatment works eligible for assistance under Title VI of the Federal Clean _ Water Act. Grants are made based on a community's ability to pay, not to exceed 97.5 percent of the total costs of pollution studies and design and construction of the project. Grants shall not exceed $2 million per project. Communities eligible for a grant may also apply for a loan. 7-2 Guarantees for Local Agency Bonds Ten million dollars is available to guarantee local agency bond issues for building — sewage treatment plants. The state bond money can be used to pay off local bonds if the local agency is unable to do so. Status of Program m A request for applications for loans for reclamation of municipal wastewater and groundwater was issued on June 13, 1989. The notice stated that about $33 million was available (bond laws of 1984 and 1988). Program Guidelines and Loan Application Forms are available from the SWRCB. With regard to the grant part of the program, the SWRCB has approved the policy for Y issuance of grants. The priority list based on requests already received and carried over from previous programs is being updated. The SWRCB is scheduled to approve the priority list in March 1990. Requests on the list exceed the $25 million available. Legislation was introduced in 1989. AB 1312 (Filante), which would provide $200 million for loans to local public agencies for water reclamation projects, subject to the approval of the voters in November 1990. A City resolution was recently approved to document support for AB 1312. MWDSC LOCAL PROJECTS PROGRAM OVERVIEW Overview The Local Projects Program is designed to provide financial support to local agencies in the development of local water supply projects to reduce their demands on Metropolitan's imported supplies. Metropolitan's net annual financial contribution is based on the amount of water delivered and would be its annual avoided energy cost for pumping a like amount of water through California's State Water Project. This amount may change yearly, subject to a minimum payment of $75 per acre-foot. Alternatively, Metropolitan would provide a capital contribution equivalent to the annual contribution. The Metropolitan Board will soon evaluate a staff report to increase the payment rate to approximately $150 per acre-foot, to represent both Metropolitan's avoided energy cost 7-3 and avoided cost for development of alternative freshwater supplies, that would result — from implementation of reclaimed water projects. The required procedural steps for execution of a local project is as follows: o A local agency proposes the reuse project to a Metropolitan member agency. M1 o The member agency submits a project proposal to Metropolitan General Manager. o The project would be examined to ensure that all qualifying criteria are met. _ o Negotiations between Metropolitan and the member agency would establish rules governing payment, role of the member agency, liability, and other related matters. o Metropolitan Board of Directors would approve the project, committing Metropolitan to participate financially. o A purchase agreement is executed between Metropolitan and the member agency. To qualify for funding, the project is evaluated on the following criteria: basic qualifications, financial assistance needs for economic viability, policy needs, technical development, regulatory needs, project yield levels, and project cost. Statusof PrQgr m Since the project inception in 1981, Metropolitan has approved participation in 12 projects which have a combined ultimate yield of more that 36,000 acre-feet per year. Currently, over 30 additional projects are in various stages of review by Metropolitan for inclusion in the program. 7-4 OTHER SOURCES Revenue bond issues, Certificates -of -Participation (COP) or Redevelopment Agency funding mechanisms are other viable options for partially funding a water reuse program. Connection charges are viable but are limited to the value of the physical connection _ itself. Reclaimed water sales generally need to be discounted to less than the equivalent potable water rate in order to create a financial incentive for user participation. The following programs for public works funding have been evaluated and determined to be inappropriate for basic financing of the City Water Reuse Project: 1. Small Reclamation Projects Act (PL 84-984) U.S. Bureau of Reclamation (USER), 2. Housing and Community Development Act of 1974 U.S. Housing and Urban Development (HUD), 3. CA Water Conservation Bond Law of 1988 (Proposition 82) Department of Water Resources (DWR), 4. CA Safe Drinking Water Bond Law of 1988 (Proposition 81) (DWR). REUSE PROJECT STRATEGY At this time, it appears that several sources of project funding will need to be tapped to make the project financially viable. It is recommended that the following program be considered: 1. Pursue a SWRCB low-interest loan. 2. Pursue participation in the MWDSC Local Projects Program. 3. Evaluate prospects for a revenue bond issue or issuance of COP. 7-5 4. Discuss prospects of project element financing by other agencies, with appropriate payback by the City. - 5. Develop a pricing policy for reclaimed water. 7-6 CHAPTER 8 PROJECT FEASIBILITY ECONOMIC ANALYSIS In order to determine the cost-effectiveness of the two-stage City reuse project, comparison should be made with projected costs of developing new water sources. As a guide, the following projected rates for Metropolitan Water District (MWD) treated, non- interruptable supplies can be assumed: Year Water Rate ($/acre -food 1990-91 230 1991-92 257 - 1992-93 280 1993-94 299 1994-95 320 2000 425 2005 460 2010 480 2015 500 A cost-effectiveness analysis of the City reuse program is summarized in Table 8-1. The table presents a staged breakdown of capital costs according to supply and distribution elements, together with project yield estimates. Historically, reclaimed water projects have been eligible for subsidized funding from MWD (minimum local project share of $75/AF), and the SWRCB (low-interest) loans at half the interest rate for state bond sales). MWD is in the process of considering an increase in the Local Projects Program rebate to as much as $150/AF. A unit cost analysis has been prepared assuming the $150/AF rate is adopted, and including: 1) unit capital cost at the State low-interest rate, 2) operation and maintenance costs, and 3) total net unit costs, including the projected rebate. Based on data in Table 8-1, the net cost of the City reuse program for the Initial Stage 1 ($254/AF) would be less than the MWD rates by 1992-1993 ($280/AF). The net unit costs of the expansion Stage 2 ($374/AF) would be less than the estimated MWD rate by the year 1997-98 ($383/AF). 8-1 The period of time necessary to fully implement these projects will approach these dates of water cost tradeoff. The project is therefore economically viable. INSTITUTIONAL FACTORS In order to implement the Diamond Bar Water Reuse Project, it will be necessary for the City to enter into various contractual agreements with various entities. The inter- relationship to be documented in these agreements is summarized on Table 8-2. Reclaimed Water Supply It will be necessary to modify the existing supply agreement between LACSD and the City of Industry (Industry) to provide additional assured supplies of reclaimed water for the Diamond Bar project. Discussions with both affected agencies indicate no obstacles to this inclusion; updating of the original agreement is presently being investigated to increase the Industry supply to 10 mgd, including additional supplies for WVWD. The modified agreement should address the following issues: 1. Firm commitment for initial and ultimate quantities of reclaimed water to be purchased by the City. 2. Price of reclaimed water purchased (approximately $30/AF). 3. Requirements for construction of additional delivery facilities by LACSD. 4. Operation and maintenance responsibilities. It may be more convenient to cover some of these issues in an additional separate agreement with Industry. Capacity Rights - Existing Transmission Facilities A separate agreement with Industry will be required to address the City requirements for capacity rights in Industry's reclaimed water pumping and transmission facilities. The agreement should address the following: 1. Appropriate method to determine assessed valuation of facilities. 2. Appropriate method to determine the City's portion of hydraulic capacity. 8-2 3. Documentation of original costs for construction of facilities. 4. Provisions for payback of value of capacity rights. Construction of New Transmission Facilities The costs presented in Chapter 6 for the new transmission facilities to connect the existing Industry system with the City distribution system represent capacity only for the City. Industry may wish to construct the facilities at a capacity to serve ultimate requirements of Industry, WVWD, Diamond Bar and other retail agencies. Under this arrangement, the City may purchase capacity rights in future facilities to be constructed by Industry, and a separate agreement between WVWD and the City would address joint construction of separate facilities. Both agreements should cover the following items: 1. Firm capacity allocation among all entities, 2. Lead agency responsible for facilities design, construction, and operations and maintenance, 3. Provisions for cost reimbursement by entities with minor capacity rights, 4. Provisions for potable water backup supply (WVWD). Transmission Wheeling It may be necessary to develop an agreement with WVWD for partial "wheeling" of City reclaimed water through the WVWD system. The transmission facilities described in Chapter 6 have been recommended to avoid any reduction of WVWD system capacity, by means of parallel pipeline construction. The concept of "wheeling" would involve periodic conveyance of City water through portions of the WVWD system at times of the _ day when the WVWD capacity was not fully utilized. As an example, it may be possible to initially convey City water during the day through the WVWD system whose capacity is maximized during night delivery periods. Detailed hydraulic modeling studies of the WVWD system and superimposed City wheeling requirements will be necessary to verify this concept, and these studies are beyond the scope of this study. It future studies confirm the viability of the concept, a transmission wheeling agreement between the City and WVWD will be required. 8-3 User Agreements A key factor in implementing a water reuse program is the successful negotiation of an acceptable contract for the use for the reclaimed water. A typical agreement will need to address several points, a tabulation of which is included in Appendix C. The Appendix present a recent amendment to the AWWA Guidelines For Distribution of Non -Potable Water, which focuses on various aspects of Institutional Arrangements which may be required for a successful water reuse program. City Ordinances for Use of Reclaimed Water In addition to the contractual agreements discussed above, it may be helpful for the City to develop and adopt one or more ordinances related to the use of reclaimed water from the City system. These ordinances could address the following: 1. Requirements that future landscape and greenbelt areas be irrigated with reclaimed water from a separate system; applicable to residential common areas (and potentially front yards), commercial areas, medians, and public recreational facilities; 2. Requirements that future industrial park high-rise structures (greater than a minimum number of stories) be constructed with a separate piping system so that reclaimed water could be utilized for toilet -flushing purposes. 3. City-wide Rules and Regulations on the use of reclaimed water (in conjunction with WVWD). IMPLEMENTATION PROGRAM It is recommended that the City undertake the following action program leading toward eventual implementation of the Diamond Bar Water Reuse Project: 1. Distribute the final report on the Feasibility Study to interested parties and agencies. 2. Initiate discussions with LACSD, City of Industry, and WVWD regarding supply of reclaimed water for the Project. 8-4 _ 3. Conduct detailed hydraulic network analyses regarding the potential City wheeling demands on the WVWD system. 4.

As the quantity of non -potable water use increases together with new and emerging applications, institutional implementation of water reuse projects will also become more challenging. The purpose of this Appendix is to generally outline the major potential institutional issues that may need to be investigated and resolved prior to completing a particular non -potable water program. It is not intended to present solutions but rather is a document to provoke thought. The Appendix includes discussion of the following topics: Contractual Requirements Potable Water Backup Systems - Water Rights - Financing Sources - Agency Communications and Needs - Paralleling Issue - Regulatory Policy References -3- E.2) CONTRACTUAL REQUIREMENTS A key factor in implementing a water reuse program is the successful negotiation of an acceptable contract for the use of the non -potable water. Some of the basic points that may be required by supplier and/or user are listed below. The tabulation is not intended to be a required list of items for all agreements, and may not be all-inclusive. 1) Delineation and responsibilities of all parties to the project (i.e. customer, purveyor, system operator, sanitation/ reclamation authority, regional funding agency), 2) Description of facilities for delivery and distribution of non -potable water (including on-site facilities as required, and ownership), 3) Quantity of non -potable water to be purchased; including maximum/minimum rates, backup supply rates, project entitlements, 4) Quality of water, including numerical objectives, provisions for variation, regulatory compliance, 5) Operating obligations of parties, 6) Pricing policy, including discount rates to provide incentives, adjustments - during contract duration, auditing provisions, impact of potential grants/loans, provisions for avoided energy costs, 7) Billing and payment provisions, 8) Limitation of use, 9) Terms and amendments, 10) Limitations on contractual commitments, 11) Indemnification -4- E.3) POTABLE WATER BACKUP SYSTEMS Because non -potable water is distributed for a variety of uses (i.e. recreational lakes, landscape irrigation, etc.) the need for a potable water back-up system should be evaluated on a case by case basis. Two general scenarios provide a beginning point for determining the need and extent of domestic water backup supplies. In cases where non -potable water is being used for fire protection, such as in remote areas where an adequate supply of potable water is not available for drinking and fire flow, or where high volume industrial users are using non -potable water for process water a back-up system with a short response time shall be considered. Under these circumstances hydraulic controls shall be included in the system to allow for immediate switching over to potable water in the event of an outage. However, consideration should be given to health department requirements which prohibit converting non -potable water piping to potable water without special pipeline connection requirements. in situations where non -potable water is being used for agricultural or landscape uses where outages beyond three days would cause serious plant damage, provisions to allow for conversion shall be included. Under this emergency scenario, provisions in the design of the potable and non -potable distribution systems shall be included to allow for a conversion within the three day window. An example would be installing a pair of tee connections between the two pipelines which could be exposed and connection by means of a reduced pressure principle device, or through an air gap into a standpipe. -5- E.4) WATER RIGHTS In the planning of a non -potable water system, water rights issues may need to be addressed. When the producer of non -potable water is not the same entity as the distributor of potable domestic water, the issue as to who should distribute the non - potable water should be negotiated. Resolution of this issue may best be addressed in a memorandum of agreement or contract. Such an agreement could also address other topics such as: a) transfer of rights between public authorities; b) rights to downstream diversion of non -potable water discharge to a watercourse; and c) non -potable water producer rights until discharged or "abandoned". E.5) FINANCING SOURCES Sources for financing non -potable water projects can be generally divided into two categories, financing for retro -fit programs, and financing for new projects. Retro -fit project funding sources - Because retro -fitting existing potable water systems with non -potable water is considered a 'conservation' measure, these projects can seek funding from a variety of State and Federal water conservation grants. The Metropolitan Water District through its "Local Projects" program will often participate in the cost of retro -fit projects if it can be confirmed that these projects will reduce the use of domestic water. An additional source of revenue for financing retro -fit projects could be obtained by delaying the changeover from domestic water to non -potable water rates for a fixed period of time. This source of funding does not result in the direct payment of funds, but rather through avoided costs for purchasing treated water, or other treatment costs. 19 New projects funding sources - In addition to the previously mentioned State and Federal Grant funds which may be available for new projects as well, the cost to fund new projects can be obtained through user fees, connection/capacity charges, bond funds, and/or State loans. The State Water Resources Control Board is implementing the Water Reclamation Loan Program established under the Clean Water Bond Laws of 1984 and 1988. Loans can be made for approved projects for up to 25 years at an interest rate equal to one-half of the rate paid by the State or preceding general obligation bonds. Additional information on non -potable water project financing can be obtained from the following sources: 1) Office of Water Recycling State Water Resources Control Board Post Office Box 100 Sacramento, CA 95801 2) Local Projects Program Metropolitan Water District of Southern California Post Office Box 54153 Los Angeles, CA 90054 E.6) AGENCY COMMUNICATIONS AND NEEDS Implementation of a non -potable water project can involve numerous agencies and/or entities to fulfill particular project responsibilities. The interrelationship of such entities in conceptually depicted on Figure E-1. Communications among involved agencies during the project planning process are vital to its success. Inter -agency memorandums -of -understanding (MOU) or memorandums -of -agreement (MOA) are helpful to formally define each agency's role, rights and responsibilities in project execution. -7 - An MOU among the State Water Resources Control Board, California Department of Health Services and the California Department of Water Resources is currently being promulgated to guide the regulatory implementation of non -potable water projects. Issues on such projects can also involve various departments within a municipality; therefore, inter -department communications are also suggested. A municipal Fire Department shall be consulted whenever non -potable water is to be proposed for fire protection purposes or other uses involving fire hydrants. it may be necessary to formulate a new public entity (i.e. joint powers agency, community services district) to effectively implement a non -potable water project. Legal advice shall be obtained in these instances, and also regarding other project institutional needs. E.7) PARALLELING ISSUE It has been claimed by certain private water purveyors that distribution of non -potable water constitutes a duplication of service under Sections 1501 through 1506 of the Public Utility Code. Under these sections of the Codes, an entity providing water service to an area is due fair compensation when another entity encroaches on the original utilities service territory. The service provided by the second entity must be the same type of service the original entity provided. The value of compensation in this type of situation could be determined as the value of facilities rendered useless, or reduced in value by loss of earnings resulting from loss of market. However, non -potable water projects implemented in a water -short area may result in a positive off -setting benefit to the private water purveyor. in water reuse applications involving potential duplication of service, communications should lead to a project of mutual benefit. i } � W Q � W h � uj �. � 3Z vl� ILl A 40 40 ( � Q a. — �- Q J V"� || k22|} !||§ , |.� . !!!I .|■& !�■ � ||)} IL | w U ��I Y CCU.

APPENDIX D SCOPE -OF -WORK PUBLIC INFORMATION STRATEGY PLAN CITY OF DIAMOND BAR Water Reclamation Public Information Services PROJECT UNDERSTANDING The City of Diamond Bar, in conjunction with Boyle Engineering Corporation, is currently undergoing a study to determine the feasibility of utilizing reclaimed water in the City. The study will examine potential reuse sites and potential customers; study reuse demands; determine reuse supplies; analyze storage needs; develop financial data and strategies; and provide recommendations for the reuse project. The City has requested assistance with the public information efforts in conjunction with this water reclamation feasibility project. although water reclamation projects are becoming more commonplace in California, the technical, financial and environmental impacts of reuse are not well understood by the media and the public. Among the real and/or perceived impacts a water reclamation project could pose to residents are environmental degradation, reduced Property values, health and safety hazards, increased traffic and construction, odor and visibility, a Without a structured exchange of technical information (translated into layperson's terms) disseminated to the media and the public, the City's well-meaning intentions could deteriorate into controversy, misunderstanding, and possible failure to implement a rf water reclamation project. 11 'o el e, SCOPE OF WORK HHK Associates recommends developing a Public Information Strategy Plan. The Plan would initially assess the existing community _ and press relations, and then make recommendations on how to involve and inform the public and media as the decision-making process evolves. The ultimate goal of the Plan will be to gain consensus of any approved water reuse projects and to gain positive recognition for the City's efforts. Once the Public Information Strategy Plan is developed, HHK Associates can offer assistance to the City by implementing recommendations with public participation such as arranging citizens' advisory committee meetings; attending workshops; and preparing agendas or other presentation materials. HHK Associates can also develop any necessary public information materials such as slide shows, brochures, newsletters and posters. Task 1 Assess existing press and community relations by meeting with appropriate city staff and consultants; and gathering and examining any news articles, editorials and letters to the editor. Task 2 Develop strategies for involving and informing the public through the decision-making process. E - Task 3 Develop recommendations for appropriate public education materials including cost estimates. Task 4 Produce and distribute press packets to local and regional media. The packet will consist of a folder with summaries of water reuse information provided by Boyle Engineering; a "Layperson's Guide to Water Reclamation;" any pertinent City Council minutes or summaries of actions and other appropriate information. Task 5 Write two press releases which will be issued in conjunction with milestones of the Water Reuse Study or subsequent events. Task 6 (Optional - Not Included In This Scope) _ Assist with implementation of any public involvement as recommended in Task 2. Develop any recommended public information materials such as brochures, information bulletins, newsletters, slide shows, etc. 3 ORDINANCE NO. 25A (1989) AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF DIAMOND BAR AMENDING SECTION 4 OF ORDINANCE NO. 25 (1989) PERTAINING TO THE POWERS AND DUTIES OF THE CITY PLANNING COMMISSION.

VAN NORT, CITY MANAGER FROM: RONALD L. KRANZER, CITY ENGINEER SUBJECT: STATUS SUNSET CROSSING ROAD AT GOLDEN SPRINGS ROAD - TRAFFIC SIGNAL REQUEST Recently the Traffic and Transportation Committee considered traffic concerns as expressed by both the Diamond Point School and PTA and did take some action regarding parking and further requested investigation of proper sight distance along Golden Springs Road with reference to the pedestrian cross walk, proper signage and speed limits on Golden Springs Road. The Committee also requested the standard investigation regarding a traffic signal at this same location. The investigation regarding the signal is now in process, but can not be completed until traffic counts are available - probably in about 3 to 4 weeks. In the mean time the City has received numerous letters and a petition in favor of a traffic signal as soon as possible. Due to the increased concern on this matter the Traffic and Transportation Committee will discuss the issue at their next regular meeting of April 5, 1990.

We feel a crossing -guard in insufficient protection for our children to cross an extremely busy road that is used as an express way for many people going to, and coming from, Chino and Phillips Ranch. Many, many times, other cars have passed my vehicle traveling at what I could estimate to be 55 m.p.h.. The icing on the cake, as it were, was on Halloween, 1989. My family and several others stood at the crosswalk to cross Golden Springs to go the the school Halloween Carnival. A car in the curb lane stopped and we proceeded to cross, fortunately very cautiously, as a pick-up came at a high -rate of speed and almost failed to stop. We stopped to allow the pick-up truck to pass although we were on the cross -walk. He hit the brakes and did stop. After we gave him a piece of our minds and pointed to the school sign, we got a mouthful of abuse and "the finger". As is sometimes the case, we do not want to have a child, or adult, injured before someone takes attention. We thank you for your time in reading this letter, and hopefully, for the wise decision you will make. Ashur & Elaine Mooshiabad March 22, 1990 RECEIVED DIAMOND BAR March 21, 1990 CITY CLERK f� Mayor Phillis Papen tR 26 Pik 2- 06 21660 E. Copley Drive, Suite 100 Diamond Bar, CA 91765 SUBJECT: TRAFFIC SIGNAL AT SUNSET CROSSING ROAD AND GOLDEN SPRINGS DRIVE Dear Mayor Papen, I would like a traffic signal at the above intersection. I understand that a petition with approximately 500 signatures of concerned parents has already been given to you. I am requesting that the City Council take action now to get the traffic signal installed at the intersection of Sunset Crossing and Golden Springs. If action is taken immediately the City Traffic Committee informed me that the light could be installed by December. A very long time away! If the Council delays in taking the appropriate action then the risk to our children increases significantly as time passes. The risk of serious accident and death is not warranted. The completion of Peterson Park scheduled for April makes my request even more urgent as many citizens will be crossing Golden Springs throughout the year to enjoy this fine recreation area. A traffic light by Diamond Point School will benefit thos who use the school and those who use the park. I believe that one of the major benefits of gaining "city" status is having local control to address our needs in a timely way. The arduous process we endured when we were under the LA County jurisdiction is no longer required. Prudent study and deliberation on this matter is necessary to be sure. Immediate action is also required! I appreciate all that you do for our city and community. Thank you for your timely attention and interest in this matter!

We feel a crossing -guard in insufficient protection for our children to cross an extremely busy road that is used as an express way for many people going to, and coming from, Chino and Phillips Ranch. Many, many times, other cars have passed my vehicle traveling at what I could estimate to be 55 m.p.h.. The icing on the cake, as it were, was on Halloween, 1989. My family and several others stood at the crosswalk to cross Golden Springs to go the the school Halloween Carnival. A car in the curb lane stopped and we proceeded to cross, fortunately very cautiously, as a pick-up came at a high -rate of speed and almost failed to stop. We stopped to allow the pick-up truck to pass although we were on the cross -walk. He hit the brakes and did stop. After we gave him a piece of our minds and pointed to the school sign, we got a mouthful of abuse and "the finger". As is sometimes the case, we do not want to have a child, or adult, injured before someone takes attention. We thank you for your time in reading this letter, and hopefully, for the wise decision you will make.

Copley Drive, Suite 100 Diamond Bar, CA 91765 SUBJECT: TRAFFIC SIGNAL AT SUNSET CROSSING ROAD AND GOLDEN SPRINGS DRIVE Dear Mayor Papen, I would like a traffic signal at the above intersection. I understand that a petition with approximately 500 signatures of concerned parents has already been given to you. I am requesting that the City Council take action now to get the traffic signal installed at the intersection of Sunset Crossing and Golden Springs. If action is taken immediately the City Traffic Committee informed me that the light could be installed by December. A very long time away! If the Council delays in taking the appropriate action then the risk to our children increases significantly as time passes. The risk of serious accident and death is not warranted. The completion of Peterson Park scheduled for April makes my request even more urgent as many citizens will be crossing Golden Springs throughout the year to enjoy this fine recreation area. A traffic light by Diamond Point School will benefit thos who use the school and those who use the park. I believe that one of the major benefits of gaining "city" status is having local control to address our needs in a timely way. The arduous process we endured when we were under the LA County jurisdiction is no longer required. Prudent study and deliberation on this matter is necessary to be sure. Immediate action is also required! I appreciate all that you do for our city and community. Thank you for your timely attention and interest in this matter!

Sincerely, Name Address CITY OF DIAMOND BAR AGENDA REPORT March 30, 1990 COUNCIL DATE: APRIL 3, 1990 TO: CITY COUNCIL VIA: ROBERT L. VAN NORT, CITY MANAGER FROM: RONALD L. KRANZER, CITY ENGINEER'iv_ SUBJECT: NO PARKING RESTRICTIONS EAST SIDE OF DIAMOND BAR BOULEVARD - GRAND AVENUE TO QUAIL SUMMIT DRIVE As part of City Council's concept approved for improving traffic flow along Diamond Bar Boulevard in the vicinity of Grand Avenue a third north bound traffic lane on Diamond Bar Boulevard was approved that will necessitate parking prohibitions during P.M. peak hours - 4:00 to 7:00 P.M. It was originally anticipated that this third lane would be put into effect as part of the overall intersection improvements, but recent evaluation of the traffic flow indicates an immediate need. This third lane would initially be utilized for right turns only into the residential areas and right turn only at Grand Avenue. This should assist the local residents and keep the through traffic in the two inside lanes. Proper signing for the "through traffic" will also be installed. And yes, this will have an effect on the bicycle lane. The details for this exact configuration are presently being prepared. Attached is the necessary resolution for the parking prohibition. RECOMMENDATION: It is recommended that the City Council adopt Resolution prohibiting parking along the east side of Diamond Bar Boulevard between Grand Avenue and Quail Summit Drive.

Surrounding Land Use and Zoning: Project site: C-1 North: R-1 South: R-1 East: RPD West: R-1 C. Surrounding General Plan: Project site: Commercial North: U-2 / 3.3-6.0 South: Commercial and U-1 / 1.1-3.2 East: Non -urban West: Open Space D. Site Characteristics_ The site is located in the Country Hills Towne Center at 21323 Cold Springs Lane. The clinic is located at the Westerly side of the shopping center. The adjacent uses include a photography studio and vacant units. The clinic currently occupies 900 square feet, but a planned expansion of an additional 1200 square feet is being petitioned for. Parking for the shopping center is adequate and the clinic expansion will not effect the parking requirements. The clinic lies 70 to 80 feet from the nearest residences. II. ANALYSIS: A. General: The proposed application requests to continue the current veterinary care services. Currently, both retail and animal care services are offered and the addition will allow greater animal care facilitation. The clinic has existed at the present location for more than three years and the growth of the community has created a demand for expanded facilities. There are three employees and no addition to that number is anticipated. The current hours of operation are from 8:30 A.M. to 6:00 P.M. Monday through Saturday and no change is requested. All signage is to remain as displayed. B. Environmental Assessment: After review of the Initial Study completed by the applicant, it has been determined that a Categorical Exemption is appropriate. III. FACTS OF FINDINGS: The project is substantially consistent with the Community Plan, Zone C-1 requirements and is projected to be in substantial compliance with the General Plan. The project will not be detrimental to adjacent properties or cause significant environmental impact. IV. CORRESPONDENCE: This item has been advertised in the San Gabriel Tribune and the Progress Bulletin newspapers as a public hearing. Notices have been sent to property owners within a 700 foot radius of the project. RESOLUTION NO.

Project 87-549, 29 Single Family Subdivision, Brea Carryon' Road This Department has reviewed the Noise Analysis prepared by Gordon Bricken & Associates for Tentative Tract 45290 and submit the following comments for your consideration: 1. The report accurately describe=_ the noise environment on the project site adjacent to the 57 Freeway in the Brea Canyon area. The site is impacted by excessive noise level= and mitigation measures are required as. presented in the report. _. . 2: The report considers two options for sound control barriers at the top of the west slope of the project site. Although, both options will result in a reduction in noise levels only Option A (16 foot barrier- wall) will effectively reduce a;.ter-ior noise level=_ on site to acceptable levels. ti. This Department considered a 16 foot barrier wall to be unacceptable; however; a 16 foot barrier was required to reduce exterior noise levels to reasonable levels. Therefore. Pfeiler & Associates Engineer's Albert E. Dayton and Dr. Frantz: C. Gomez of this Department made a site visit and determined that a combination of a berm/wall of 16 feet Nould be -acceptable.

Various oak trees on the 20.58 acres of the subject property are proposed to be removed as a result of development in accordance with said Tentative Tract No. 45290, filed concurrently with this application. As a result of our field observations, we have determined that one hundred fifteen (115) oak trees are found on the property. A precise count has been difficult to obtain due to site -characteristics such as steep slopes, dense underbrush and widespread poison oak. The oak tree permit site plan assigns a number to each of the trees f-om 1 througn 115. Trees numbered 1 to 82 are situatad within proposed cut and fill excavations where the change in grade necessitates their removal. Subsequent to tree removal, placement of compacted fill and construction of paved drainaae swales will prevent any soil erosion by surface drainage. Trees numbered 83 to 113 are intended to remain. Trees numbered 114 and 115 have been burned by a recent fire and appear destroyed. As a means of protecting the trees to remain, a fend no less then four feet high will be installed along the dripline of the trees and will remain during the entire construction phase. There will be no storage of equipment, machinery or building materials within the dripline of t:nese trees. When feasible, excavation within the dripline or within 10 feet of the trunk of the tree will be accomplished using hand tools or small hand power equipment. Each tree to remain along the lower slope elevations near construe --ion will be prooerly identified in the rield using colored flagaina or other means acceptable to the Director of Plannina. Los Angeles County Regional Planning Los Angeles, CA 90012 Attention: Planning Director Subject: Tentative Tract No. 45290 July 1, 1987 Page 2 Natural open space areas in this project will remain undisturbed throughout the construction phase. Many of the oaks and miscellaneous trees situated on the north facing slope will be saved. Since no grading equipment will travel in these areas, their health should not be endangered. As specified in the ordinance, the Planning Director or Commission may require that two I5 -gallon oak trees be planted for each natural oak tree removed. This ratio will be difficult to achieve on this site due to lack of suitable locations. We assume the natural areas will remain undisturbed. New trees could be planted on the constructed slopes of Lots 1 through 6 and 18 through 29. Oak trees planted on the south facing slopes of lots 7 through 17 may not be effective. The oak tree permit site plan shows the location of 70 new trees on-site. We request that these site characteristics be considered when determining the replacement requirements. Tentative Tract No. 45290 depicts street and pad elevations necessary to develop 29 residential lots. In order to construct this subdivision, the canyon must be filled to an elevation which provides sufficient pad depth. Only in this manner will site improvements become cost feasible for the developer. Alternate development plans cannot yield the same number of lots and does not allow reasonable or efficient use of the property. With the oak trees situated within the graded areas of the proposed plan, it becomes necessary to remove the trees.

Diamond Bar Boulevard 1� Diamond Bar, California 91765 -d Dear Mr. Dayton: Re: T.T. 4290 Tree Study In accordance with our arrangement, we have just completed our study of the oak trees at this Diamond Bar, California site. A tree locations and some tree forms tree map showing the approximate are enclosed; our report follows. Basically, this study evaluated all of the coastal live oak trees (Quercus agrifolia) having trunk diameters greater than 8" on this - this encompassed a total cf 147 trees, which have all property - been identified by meta_ togs Placed on their trunks. For the most part, these trees are in less than average condition as many of them have been subjected to past fire damage. Despite this, we are recommending that only 7 trees be removed for horticultural reasons. Details of our findings on all of these trees are provided on the tree forms which are provided, and our comments on them follow. TREE RE.SOVALS - As mentioned, we are recommending that 7 trees be removed. Six of these are very hazardous as they have sustained heavy trunk fire damage, while the other tree is necrotic (dead). Exact details on these trees are shown on the enclose' -;removal tree forms; should there be any questions on them, please refer them to US. All of these trees have had 'Y's painted on their trunks. OTHER OAK TREES - The remaining 140 trees could be classified as candidates for preservation. Details of our horticultural evalu- ation on all of these trees are shown on the remaining tree forms, which are also provided. Basically, these forms snow our findings and recommendations which are itemized under the evaluation, rating; and treatment sections of the form. The evaluation section on the tree form contains data as to each tree's size and other health or branching information. As artoult of that information, we assigned health and aesthetic ratin G r f above average) to 'D' (below each tree. Ratings ane from 3 ( - In average), with a 'C` representi_lg a tree Of average cualit;- - a.ddition to these letter values, we further assigned Plus 11)better minus (-) signs t0 some trees t0 indicate is it was sliouldfidentifv or worse than the lettered value.

Dayton re: TT 45290 Tree Study September 11, 1988 Page 2 five trees (Nos. 20, 38, 80, 105, and 120) have very limited value (D-) due to the trunk damage or severely crowded growing conditions. Such trees should not be built near; otherwise, they would be best removed. The treatment section of the tree form outlines that work that is needed on each tree. Mainly this work will consist of the removal of dead wood and stubs -- and on some trees, limbs for clearance. Essentially, Mr. Dayton, this completes our horticultural evalu- ation of these trees. Please recognize that no developmental impacts have been determined as that information is not available to us. Hopefully, you will find this report satisfactory. Please call us if there are any questions on it. Respectfully, Paul A.

The following comments/requirements for this tentative map are in- dicated -by an X in the appropriate box along the left margin of the page. Details and notes shown on the tentative map are not necessarily approved. Any details or notes which may be inconsistent with requirements of ordinances, general conditions of approval, or Department policies must be specifically approved in other conditions, or ordinance requirements are modified to those shown on the tentative map upon approval by the Advisory agency. Q The distances from the proposed lot/parcel lines to the buildings which are to remain must be shown. If such distances will create nonconforming conditions under Building Code Chapters 5, 18, 19 and 21 or Zoning Ordinance requirements, such lot/parcel lines shall be relocated or the non -complying conditions of the buildings shall be corrected prior to the division of land. 0 The relationship of existing buildings/sewage disposal component to the new lot/ parcel lines will create conditions that do not comply with the Building Code/Plumb- ing Code/Zoning Ordinance. These non -complying conditions shall be corrected or the lot/parcel lines relocated prior to the division of land.

The findings are as follows: A. SOUND CONTROL BARRIER The County usually does not require sound barriers (please see Ordinance 11,741). If sound walls are considered, then, the design has two options, which are: : OPTION A -- Erect a 16 foot sound wall at the top of west slope at the rear of building pads 1 to 7 as is shown on Exhibit 7. OPTION B -- Erect an eight foot (8') sound wall at the top of the west slope at the rear of building pads 1 to 7 as is shown on Exhibit 7. B. INTERIOR NOISE CONTROL The --interior noise control measures will vary with the sound control barrier options. The variations are as follows: A. BARRIER OPTION A -- Standard construction minimums should provide adequate noise reduction to insure 45 CNEL interior levels. B. BARRIER OPTION B -- Building 1 to 9 may require special building construction in the form of special glazing treatments. 1621 East Seventeenth Street.

Included in this report is a discussion of the expected exterior community noise environment and the recommendations for control of noise in interior living areas. A vicinity map showing the general location of the construction site is presented in Exhibit 1 -- Site Location Map. The proposed development will consist of 29 single family detached dwellings on terraced pads. 2.0 APPLICABLE NOISE CRITERIA The County of Los Angeles requires all residential projects to conform to the requirements of Table 1. TABLE 1 APPLICABLE NOISE CRITERIA M Exterior...... 65 CNEL(2) Interior......45 CNEL (1) Please see NOISE RATING METHODS (Appendix 1) for complete explanation of acoustical terminology. (2) The County does not actually state any exterior require- ment but, as this level is a standard exterior require- ment for many Southern California communities, it was chosen as a target level for analytical purposes. Note also, Ordinance 11,741 does not require exterior noise control. 1621 East Seventeenth Street.

Measurements are conducted using a Bruel and Kjaer (B & K) Model 2209 Type 1 Sound Level Meter, a B & K Model 2306 Strip Chart Recorder, and a B & K Model 4426 Statistical Noise Analyzer. The Average Noise. Level reported from this measurement was 64 Leq. The measurement was taken at a point 525 feet from the centerline of Route 57 Freeway. The measurement locations are shown on Exhibit 4. A ten minute traffic count was taken during the measurement period. The results of that count are listed in Table 2. TABLE 2 TEN MINUTE TRAFFIC COUNT AUTOS MEDIUM TRUCKS HEAVY TRUCKS TOTAL 10 MINUTES L,382 69 148 1,599 HOURLY EQUIVALENT 8,292 4L4 888 9,594 PERCENTAGE 86.4 4.3 9.3 100.0 The primary function of the measurements is to cali- brate the Noise Model (FHWA RD -77-108) used to compute the CNEL data. The model relies on the acoustical metric of the average noise level (Leq). By taking the traffic count during the measurement, calculating the Leq value for that sample, and comparing it to the measured sample, it is possible to calibrate the CNEL model for any factors which are present and not adequately identified in the prediction equations. The computer printout is attached in Appendix 2. The calculated level and the measured level are compared in Table 3. TABLE 3 COMPARISON OF CALCULATED AND MEASURED AVERAGE NOISE LEVELS Calculated 64(l) Measured 64 (1) Level includes a field-of-view correction factor of -11 dBA 4 There is no difference between the calculated and the measured values. Therefore, no other corrections, aside from the field-of-view correction need be applied. 4.0 DESIGN NOISE LEVELS The expected future roadway noise impact was projected using the Federal Highway Administration's Highway Noise Prediction Model (FHWA RD -77-108) together with the several roadway and site parameters of this project. The key input parameters which determine the projected impact of vehicular traffic noise include the roadway crossection (e.g. number of lanes), the roadway active width, the average daily traffic (ADT), the vehicle travel speed, the percentages of auto and truck traffic, the roadway grade, the angle -of -view, the site conditions ("hard" or "soft"), and the percent of total average daily traffic which flows each hour throughout a 24-hour period. The forecast traffic volumes were obtained from CALTRANS. The percentage of truck traffic was obtained from typical freeway counts by CALTRANS as was the distribution by time -of -day. The input data is listed in Table 4.

In using data to construct noise contours, it must be remembered that slope shielding will alter the contours from the free field case. While the proposed grading will alter the topography from the existing conditions, the effect will stili be present. Four crossections were selected which were used to compute noise reduction factors. The noise reduction calculations were carried out (Appendix 4) for the case at ground level based on the proposed grading map. The effects on the 5 noise levels, as a function of distance from the property line, are plotted in Exhibits 5-A to 5-D. The resulting contours are shown on"Exhibit 6. Inspection of Exhibit 6 shows the noise level at the building pads nearest the freeway to be at 80 CNEL. 5.0 MITIGATION 5.1 EXTERIOR ' The mitigation of exterior noise would require a barrier along the freeway. For purposes of calculations, the barrier is presumed to be at the top -of -the -slope along the rear of building pads 1 through 7 and intended only to reduce sound level to 65 CNEL at ground level. The barrier location is shown on Exhibit 7. The assumptions for the barrier calculations are listed in Table 5 on the following page. The results of the barrier calculations, contained in Appendix 4, show that a 16 foot sound wall will be needed to reduce noise levels to a maximum exterior level of 65 CNEL for all lots. The resulting affect on the noise levels, as a function of distance from Route 57, are plotted in Exhibits 8-A through 8-D. The resulting contours show that a 16 foot high sound wall is capable of protecting the entire project However, aesthetic and economic reasoning deem a'16 foot wall unacceptable. As a comparison alternative, the effect on the noise levels, as a function of distance from Route 57 are plotted on Exhibits 10-A through 10-D using an eight foot (8') sound wall. The resulting noise contours, shown on Exhibit 11, show that adequate noise protection would result for all lots except Lots 1 to 9 inclusive. Lots 1 to 9 would see maximum levels of 70 CNEL. This means that some extra interior mitigation would be necessary for these lots. However, an eight foot (81) sound wall will prove aesthetically pleasing while interior mitigation for Lots 1 to 9 will prove far less costly than the 16 foot sound wall. From this comparison, it would appear that an eight foot (8') sound wall would be the more practical exterior mitigation. .,or TABLE 5 BARRIER ANALYSIS GENERAL ASSUMPTIONS FOR RECEIVER AND SOURCE GEOMETRY R=E=C=E=I=V=E=R=====A=S=S=U=M=P=T=I=O=N=S=====_______ HORIZONTAL GEOMETRY Distance behind top -of -roadways barrier: 5' to 10' Distance behind individual patio and balcony barriers: 1' to 3' VERTICAL GEOMETRY Height above pad for ground level receivers: 5' Height above pad for second level receivers: 14' S O U R C E _ A S=S U M P T I=O=N=S_____________ HORIZONTAL GEOMETRY* VERTICAL GEOMETRY For roadways with grades no greater than 2%, all vehicles were located at the single lane equivalent acoustic center of the full roadway.

Analysis and recommendations for control of outdoor -to -indoor noise intrusion are presented in this section. 7 N The analysis is based on the typical spectra expected for the primary sources of community noise impact, the typical octave -band transmission loss for each element in the planned building shell, the relative square footage of each element of the planned building shell, the expected typical interior surface treatment, and the acoustical absorption coefficient for each interior surface treatment. Corrections for the "A" Weighted room absorption factors are also included. Each component of the building shell (e.g. exterior wall, windows, doors, etc.) provides.a different amount of transmission loss for each "A" weighted octave band of community noise. With the knowledge of the building shell components and their individual octave band transmission loss values for the noise sources, calculations of the composite building shell transmission loss can be made for each room. In some situations, the room has exterior components exposed to different levels from the same source. In cases where this is true, the transmission loss values are adjusted to include the source noise differences, and the entire calculation is referenced to one exposure. Usually, this is the face with the highest noise level. Without building plans, exact specifications cannot be derived. However, some general conclusions may be drawn which help establish the magnitude of possible corrective action. In general, the buildings are going to yield a minimum of 20 dBA noise reduction with the windows closed and 12 dBA with the --windows open. This means that 45 CNEL can be achieved with outside level below 65 CNEL for the closed window case (65-20=45) and 57 CNEL for the open window case (57-12=45). Initially, the closed window option is the case that most limits the extent of building corrective action. If no sound wall is constructed, then, the required interior noise reductions would range from 20 dBA, for Lots 13 to 22 and up to a 35 dBA reduction for Lots 1 to 6. This situation would prove costly as extra interior mitigation would be necessary for 69 percent of the project. If an eight foot (8') sound wall is constructed, then, the required interior noise reduction would range from 20 dBA for Lots 10 to 29 up E to a 25 dBA reduction for Lots 1 to 9. This situation would prove less costly as interior mitigation would be necessary for 31 percent of the project while mitiga- tion steps themselves would be minimal. Finally, the use of a 16 foot sound wall will provide enough shielding so that no interior mitiga- tion, other than standard construction minimums, will be necessary to insure the required 45 CNEL interior level. However, the 16 foot sound wall is aestheti- cally unpleasant and may prove more costly than the interior mitigation used with the -alternative sound wall height. When all elements of a building are considered, the noise reduction usually exceeds that of the glass alone. However, as a minimum, the noise reduction will not be less than the transmission loss of the glass up to a value of 32 dBA. Over 32 dBA, combinations of glass and other building changes are_ usually required. The list in Table 6 provides "worst case" guidelines. Naturally, actual plans should be calculated when available.

(3) STC=46 is special design. STC=38 is special design. STC=30 is standard roof. All buildings, within 1,000 feet of the free- way, will need to keep the windows closed to achieve 9 45 CNEL. As a result, it is desirable to air condition the buildings. 5.3 PLAN CHECK As previously mentioned, final plans must be . reviewed prior to issuance of building permits to ensure compliance with the County's require- ments.

CORDON BRICKEN & ASSOCIATES C ONSULTING ACOUSTICAL and ENERGY ENG RS A P P LOS ANGELES COUNTY'S NOISE STUDY GUIDELINES cam. 12 Ana California92701 • Phone(714)835-0249 COMMUNITY NOISE InaM e- These guidelines are designed to assist those persons who are assessing the community*noiseenvironment for residential and other sensitive uses in Environmental Impact Reports. Since there are so many different sources of noise and the effect of these sources is largely dependent on the area's physical and environmental charas- teristics, it is impossible to develop a set of guidelines which would cover every situation. However, it is possible to develop minimum criteria which will insure that the basic information is a available so that an informed decision can be made about the noise impacts related to any project. The study should be prepared by 'individuals having previous experience in acoustical analysis: x. A noise assessment is normally required if any one of the follow_ -j ing conditions are mets 1. The project is located within 1,000 feet of a major_ roadway and the line -of -sight (LOS) is unobstructed; or, 2. The project is located within 500 feet of a major roadway and the LOS is obstructed; or, 3. The project is in the proximity of the flight path_ of an airport; or, 4. The project is within 1,000 feet of a major stationary noise source (e.g., a steel mill or amphitheatre); or, 5. The project is located within 700 feet of the mainline track of a railroad or within 400 feet of any other railroad line; or, 6. The project will increase the ambient noise distribution.

Approximately six man days were spent in the field on this project during which time thirteen exploratory pits were excavated, two 24 -inch diameter borings were drilled and geologic mapping of the pro- perty was performed. Representative samples of earth materials that occur on the site were obtained and transported to our laboratory for analysis. Geotechnical field data is shown on the enclosed Tentative Tract Map, dated December 1987, with a revision date of February 1988. The plan, drawn at a scale of one (1) inch equals 50 feet with contour intervals of 2 and 10 feet, was prepared by Pfeiler & Associates, Engineers. May 23, 1988 Work Order 11044-A Page 2 This transmittal contains an assessment of the on-site geologic and geotechnical conditions and an evaluation of the proposed development and grading. Included in the report are Log of Exploratory Pits and Borings, laboratory test results, general earthwork specifications and typical construction details. SITE DESCRIPTION The site lies in hilly to mountainous terrain within the north- westerly facing slopes of the Puente Hills. The site consists of two northwesterly trending ridges with an intervening northwest- erly draining canyon. The property occupies gentle to steep slopes, locally covered with wild grasses; wild walnut, willow and oak trees; and a dense growth of poison oak, especially with- in the canyon bottom and attendant slopes. The area above the canyon, below developed Tract No. 31150, is relatively flat. A compacted 1.5:1 fill slope encroaches the site below Autumn Glow Drive and occupies a portion of Lots 1, 2, 28 and 29. Total relief on-site is about 282 feet and natural slopes are flatter than 2:1 with localized areas being as steep as 1:1. An unimproved road skirts the northerly property line as shown on the Tentative Tract Map. The road is a Southern California Gas Company service road accessible through a locked gate off the cul-de-sac of Morning Canyon Road. The site is also accessible PACIFIC SOILS ENGINEERING, INC. May 23, 1988 Work order 11044-A Page 3 on foot from the terminus of Autumn Glow Drive. The location of the property relative to the surrounding arterial streets is shown on the vicinity map displayed on the Tentative Tract Map. Primary drainage on the property is northwesterly via the exist- ing canyon and is limited to rainfall per se. However, water does issue from an existing storm drain that drains a portion of Tract No. 28579 in the vicinity of Lots 27 and 28. Surface water currently ponds at the mouth of the canyon. The ponding is a result of the relatively flat grades in this area resulting from fill placed during past freeway construction. The large amount of existing vegetation and surface debris compounds the drainage problem. Developed properties exist along the southerly and easterly peri- phery of the subject property. A buried gas line exists above the top of the proposed south fac- ing cut slope and the northerly tract boundary line on Lots 7-8 and 11-17, inclusive. Also a 36 inch MWD water line exists both on and offsite of the westerly tract line as shown on the accom- panying plan. Its location is noted in the field by a MWD I.D. A sewerline parallels the MWD waterline. The northerly portion of the line has been abandoned. The sewer flows northerly from Tract 28579 approximately 180 feet and the turns westerly under the 57 Freeway. PACIFIC SOILS ENGINEERING, INC. Page 4 May 23, 1988 Work Order 11044-A PROPOSED DEVELOPMENT The tentative 50 -scale grading plan for Tract No. 45290 indicates the creation of 29 lots for single-family residences with attend- ant access streets. Proposed vehicular access into the property is to be via the extension of Autumn Glow Drive. Cut slopes appear to be designed primarily at 1.5:1 with that area above Lots 17 and 18 being constructed at a compound 1.5:1 to 5:1 ratio. The compound slope is to be about 157 feet high with the lower 1.5:1 portion attaining a height of about 94 feet. southerly facing cuts ranging less than 76 feet high at 1.5:1 are proposed above Lots 7-8 and 11-16 inclusive. The highest fill slope to be constructed at 1.5:1 is to be about 50 feet high and it occurs below Lots 4 and 5. Grading is to be accomplished by conventional cut and fill mass grading techniques with the canyon to be filled with materials derived from the proposed cut slopes. It is assumed that the development will be one (1) or two (2) story wood frame structures. While loading information was not , it is anticipated that footing loads will provided this office be light to moderate. GEOLOGY StratiaraphY at depth, is underlain by bedded shales, silt The entire property PACIFIC SOILS EIVOINEEFIINO, INC. May 23, 1988 Work Order 11044-A Page 5 stones and sandstones of the Puente Formation of upper Miocene Age which are mantled in part, by various Holocene surficial deposits. A brief description of the on-site earth materials is as follows: Fill (af): Loose fill, evidently placed as part of the 57 Freeway construction and consisting of loose, soft wet clays containing shale and sandstone fragments, occupies the relatively flat area encompassing portions of Lots 2-6 inclusive and Street "A". This fill is at least 12 feet thick (Pit P-2) as the entire fill se- quence was not penetrated. Based on data from Pits P-3, P-4 and P-5, surface soils were not removed prior to placement of this fill. In Pit P-4, a 4.0 ft. sequence of fill (from 3.5 to 7.5 ft. in depth) may represent a compacted interval as an extension of the existing fill slope below the present terminus of Autumn Glow Drive. This fill also rests on soil, however. Colluvium: Deposits of fine-grained slope wash, too small to map occur on the lower slopes of the ridge flanks. These deposits appear to be no thicker than 8 feet. Alluvium ( aq 1): Alluvial deposits occupy the canyon bottom. The alluvium consists primarily of loose, dark gray -brown clayey silt containing shale and siltstone fragments. The thickness of this PACIFIC SOILS ENGINEERING. INC. May 23, 1988 Work Order 11044-A Page 6 deposit is not known as the canyon was not accessible to the back- hoe or drilling equipment. Landslide Deposits ( 10 s): Boring No. 1 encountered approximately eight feet of slide debris consisting of broken, dry fragments of siltstone, shale and sandstone below the surface soil/colluvium- The in-place rocks are faulted, sheared and folded at depth below the base of this slide. Movement was probably due to the fractured nature of the bedrock abetted by naturally daylighted bedding. Other minor slope failures have been mapped on the northwesterly facing slope of the southernmost ridge based solely on topographic expression. For this reason, they are questioned on the map. Bedrock (Ty): Bedrock underlying the property is assigned to the Puente Formation and is comprised of bedded shales, siltstones and sandstone, that display variable attitudes because of drag folding associated with northeasterly trending faults that were mapped on adjacent Tract 39679 to the north and projected onto the subject property. Attitudes measured in the exploratory pits on the north- ernmost ridge confirms the existence of the faults. SEISMOT CE TONIC SETTING The general area in which the site lies can be considered seismi- cally quiescent. Strain release maps (Allen, et al., 1965) for PACIFIC SOILS ENGINEERING, INC. Page 7 May 23, 1988 Work order 11044-A the period 1934 to 1963, indicate less seismic activity than for many other sections of Los Angeles County. According to Hill, et al, (1964) the nearest epicenters, some 15 miles to the northeast, exhibited magnitudes ranging between 4.5-4.9 on the Richter scale. No major earthquake has occurred along the section of the San Andreas fault system nearest the site since 1857. Only minor events appear associated with the Sierra Madre -Cucamonga and Whittier -Elsinore fault zones, insofar as historical records go. This overall picture of quiescence, however, may well be mislead- ing. Physical evidence along both these systems tend to indicate potential for moderate to large-scale events. SEISMICITY Several significant active faults are near enough to the -site that any future movements thereon might affect structures on the pro- perty during their lifetime. An active fault as defined by the California Council on Intergovernmental Relations in the General Plans Guidelines, 1974, is: "A fault that has moved in recent geologic time and which is likely to move again in the relatively near future. For geo- logic purposes, there are not precise limits to recency of movement or probable future movement that tdefine a 'active fault'. Definitions for planning pulp ears or more the order of 10,000 years or more back and loo Y are forward. The exact time limits for planning purposes usually defined in relation to uses and structures." AC�_FAULTS The February 9, 1971 "San Fernando" earth - San Fernando Fault: PACIFIC SO1L5 ENGINEERING, INC. Page 8 May 23, 1988 Work Order 11044-A quake (Magnitude 6.4) was generated along an east -west trending, northerly dipping reverse fault. Its closest trace to the site is approximately 40 miles to the northwest of the site. Yerkes and others (1974) indicate that during post -earthquake trenching in Lopez Canyon, a buried eroded fault scarp 3.3 feet high and aligned with the 1971 ruptures was uncovered. Subse- quent radiometric dating of wood fragments buried in debris below the fault scarp indicated a date of 100-300 years before present. If the scarp is indicative of a single movement, it is possible that an event larger than the 1971 earthquake may have occurred along the San Fernando fault zone (100-300 years before present), in that the vertical displacement in the 1971 event in Lopez Canyon was about 3.1 feet. Sant Susana Fault- In general, this east -west trending fault zone is characterized by low -angle thrusting, dipping northward along its sinuous trace from the Santa Susana Mountains into the San Gabriel Mountains. The closest trace of this fault zone lies approximately 50 miles northwest of the site. The recency of movement along the Santa Susana fault is debatable. Wentworth and Yerkes (1971) suggest late Quaternary movement as illustrated by basement rock overlying the younger Plio-Pleistocene Saugus Formation. Several other authors (Bishop, 1950; Slosson and Barn- hart, 1967) have suggested that late Pleistocene displacement has PACIFIC SOILS ENGINEERING, INC. Page 9 May 23, 1988 Work order 11044-A occurred along the fault. The geologic map accompanying Califor- nia Division of Mines and Geology Bulletin 196 (1975) shows numer- ous surface breaks along the Santa Susana fault zone associated with the San Fernando earthquake. However, Saul (1975) states that the Santa Susana fault has probably been inactive since the middle Pleistocene. The preponderance of available evidence strongly suggests that the Santa Susana fault has moved during Holocene time and probably within the very recent past. San Andrea �'au1t Zone: The San Andreas fault zone can be traced continuously for 620 miles from Point Arena in northern Califor- nia to the eastern side of the Salton Sea where its trace is con- cealed by alluvium. Earthquake epicenters from the Salton Sea south to the Gulf of California suggest that the fault zone con- tinues into the Gulf (Richter, 1958). Thus, the fault zone is over 700 miles long. In northern California, the fault extends seaward at Point Arena. Because ground rupture occurred at Shelter Cove during the 1906 earthquake, Curry and Nason (1967) show the fault trending north parallel to the coast to Shelter Cove rather than continuing northwest to Point Arena to account (a) for the ground rupture and also (b) that seismic profiles showed no evidence of the northwest extension of the fault northwest of Point Arena. on the other hand, based on accurate epicenter determinations and PACIFIC SOILS ENGINEERING, INC. Page 10 May 23, 1988 Work Order 11044-A first -motion studies, Bolt and others (1968) indicate that the fault bifurcates near Cape Mendocino; one branch bends westward to join the Mendocino Escarpment, and the other branch continues on.a northwesterly strike. North and south of the Transverse Ranges, the strike of the fault is approximately northwest; in the Transverse Ranges the strike is west-northwest. The dip of the fault is approximately vertical and the sense of motion is right lateral. The total amount of horizontal displacement on the fault appears to be 160-175 miles since the Oligocene (Crowell, 1962). The potential level of seis- mic activity along the entire fault system from Hollister to the Mexican border is high except for the fault segment from the Carrizo Plain to the vicinity -of Cajon Pass (Allen and others, 1965; Bolt and others, 1968; Bolt and Miller, 1971). A microearth- quake survey of the fault system also supports this view (Brune and Allen, 1967). However, the 1857 Fort Tejon earthquake (M8+) ruptured the ground surface from the vicinity of Cholame to some- where between Cajon Pass and San Gorgonio Pass (Wood, 1955; Allen, 1968). Offset stream channels in the Carrizo Plain indicates that horizontal offset associated with this break may have been as much as 33 feet (Wallace, 1968). This segment of the fault is "locked" and it is likely that the next great earthquake in California may occur along this section (Allen 1968). Allen (1968) also suggests that activity on the fault within the Transverse ranges occurs by PACIFIC SOIL13 ENGINEERING, INC. Page it May 23, 1988 Work order 11044-A large infrequent earthquakes rather than by small earthquakes and/or creep. The site is approximately 28 miles southwest of the trace of the fault. Nem Tna�ewood Fat>>t Zone: This active structural zone has undergone major right -lateral slip and separates continental rocks from Franciscan basement at depth. From a point about 23 miles southeast of the site it extends southeastward for about 45 miles across the Los Angeles Basin and continues for an unknown distance beneath the Pacific ocean. The Newport -Inglewood fault is consid- ered the source of the 1933 Long Beach earthquake, M 6.3. This subsurface fault zone consists of interrelated faults and folds in a sedimentary section about 12,000 feet thick, which extends into basement rock as a relatively simple fault zone.

Previous subsurface is fault by this firm revealed displaced soil horizons; thereby gorizing it as active. The northeast -trending San Jose fault ex- tends obliquely between the Sierra Madre-Cucamon9 a and Whittier - Elsinore fault systems. This suggests that the San Jose fault may be an expression of an on-going stress interaction between these two main zones. Should this be the case, one would not expect sufficient this smaller intervening fault zone to develop stresses to generate very large events. Thus, major events and large dis- placements should occur along the two main zones and subsequent P occur along the reaction or in -sympathy stress relief would likely San Jose fault zone. Such a concept supports a lesser probable the Los Angeles magnitude for the San Jose fault than indicated by potentially County Seismic Safety Element (1974) which lists it as p active and cites a maximum credible event of 6.2 Richter Magni- tudthe e. The recorded 4.5-4.9M San Jose events coupled with cept of subsidiary or sympathetic reaction supports a possible 5.5M event. „�mTa r • v ACTIVE FAULTS Aotentially active fault as defined in the California Council on P Intergovernmental Relations in the General Plan Guidelines, 197 , is as follows: "These faults are those bassurfacevrupturesdoraearthquakesalong h no known historical ground show strong indica- tionsoccurred.

May 23, 1988 Work Order 11044-A Page 17 Known potentially active faults along which any future movement most likely could affect the site are as follows: Walnut Creek Fault: This fault, about 10 miles in length, is NE -SW trending and forms part of the northeast border of the San Jose Hills. The existence of the fault is suggested by water level differences across the trace of the fault, and oil -explor- ation data substantiate the fault at depth. Because it appar- ently offsets recent alluvial deposits in the subsurface, it is considered to be a potentially active fault. A maximum credible event of magnitude 6.2 is considered for this fault (Los Angeles County Seismic Safety Element, 1974). This fault is about 6 miles northeasterly of the property at its closest point. ACTIVE EARTHQUAKE FPTCENTERS Proximity of the site to earthquake epicenters of 6.0 or greater within 90 miles of the site are listed in Table A. PACIFIC SOILS ENGINEERING, INC.

However, enough seismic events of magnitude 6.0 or greater have occurred in Kern -Los Angeles -Ventura counties to indi- cate that such events could recur within the life of the proposed structures. Presented in Table B are some general guides for maxi- mum credible and maximum probable earthquakes and maximum expect- able peak ground acceleration for some of the previously described fault systems. PACIFIC SOILS ENGINEERING, INC. May 23, 1988 Page 19 Work Order 11044-A "The maximum credible earthquake is the maximum earthquake that appears to be reasonably capable of occurring under the conditions of the presently known geological framework. A maximum probable earthquake is the maximum earthquake that appears to be reasonably expectable within a 100 year period" (Greensfelder, 1974). Maximum peak accelerations in bedrock (Schnabel and Seed, 1972) are based on either the maximum credible or probable earthquake that could occur along each causative fault at its point nearest the subject site (Table B). It is emphasized that these figures are general, particularly in the higher ranges due to lack of data points. As noted by Ploessel and Slosson (1974), "Although the maximum (peak) ground or bedrock acceleration is one of the factors for computing ground response at a site, it generally is not the same as design accelerations. Thus, the maximum acceleration should not necessarily be utilized in empirical engineering formulas cur- rently in use to determine earthquake -resistant structural de- sign." Page and others (1972) have noted that a single peak of intense motion (maximum or peak acceleration) may contribute less to cumulative damage potential than several cycles of less intense shaking. Therefore, repeated high ground acceleration should be of greater concern in structural design PACIFIC SOILS ENGINEERING, INC.

Typically, the re- peatable high ground acceleration averages 65 percent of the peak ground acceleration for sites within 20+ miles of the epicenter. Local subsurface conditions at the site, nature of alluvium and rock and depth of basement between the site and the fault systems may induce variations. Structural design of future buildings should be based on current design practices for similar types of buildings in the area.

May 23, 1988 Work Order 11044-A Page 21 contained herein do not necessarily represent an end-point in the understanding of interrelated factors which influence seismic ef- fects on engineered structures. The science is currently in a infant stage and new data are being acquired, studied and evalu- ated. Later studies may disclose that currently accepted conclu- sions are, in part, or totally, erroneous. It should be noted that no subsurface site spectral response studies were conducted as part of this study. PRT ARY EFFECTS Ground Motion: Although no major historical epicenters are known within the immediate vicinity of the property, the proximity of several active faults indicates the likelihood that the site may at some time be subjected to at least moderate ground motion. Spectral characteristics of strong seismic surface motion display a dependence on many factors including possible subsoil effects, seismogenic mechanism (Brune, 1970), the wave propagation pattern (Haskell, 1969), nature and geometry of geological discontinui- ties along the propagation path (Haskell, 1962), surface topo- graphy (Boore, 1972), and subsurface geometry (Wong and Trifunac, 1974) . Although many investigators, including -Duke (1958) and Idriss and Seed (1967) have used subsoil conditions to explain ground PACIFIC SOILS ENOINEERINO, INC. Page 22 May 23, 1988 Work Order 11044-A motion other studies such as by Trifunac and Udwadia (1974), question the effectiveness of determining local amplification on the basis of subsoil conditions. In view of the foregoing, as part of this preliminary study, a general guide for possible ground acceleration is based on the Schnabel and Seed (1972) plots of maximum acceleration versus distance from the potential causative fault. Derived values are tabulated in Table B. In this tabulation, hypothetical expectable events are considered at the nearest portion of the fault. These magnitudes have been selected primarily from literature values of either real events or those calculated from empirical formula and curves compiled by Bonilla (1970) relating fault length and magnitude. Sets of empirical data such as those of Schnabel and Seed (1972) have certain validity in the far -field, but knowledge of near -field effects is so slender that it is difficult in preliminary format to evaluate the potential for ground acceleration. Ground Rupture: Ground rupture as a result of fault activity of the aforementioned faults is not expected within the limits of the proposed development. Liquefaction: Liquefaction occurs when dynamic loading of a sat- urated sand or silt causes pore -water pressures to increase to levels where grain -to -grain contacts are lost and the material temporarily behaves as a viscous fluid. Liquefaction can cause PACIFIC BOILS ENGINEERING, INC. May 23, 1988 Page 23 Work Order 11044-A settlement of the ground surface, settlement and tilting of engi- neering structures, flotation of bouyant buried structures and fissuring of the ground surface. A common manifestation of lique- faction is the formation of sand boils --short- lived fountains of soil and water that emerge from fissures or vents and leave freshly -deposited, conical mounds of sand or silt on the ground surface. This phenomena should pose no stability problems in the bedrock that underlies the proposed development. The loose alluvium in the existing canyon will be removed and replaced with a compacted fill with a subdrain in the draw bottom for groundwater removal. Approximately six (6) man days were spent in the field generating surface and subsurface geotechnical data. A total of 13 explor- atory pits were excavated in the accessible low lying area. Two 24 inch diameter borings were excavated with a truck mounted buc- ket auger drill rig in the proposed cut slope area at the rear of Lots 17 and 18. overall, access to the site is limited due to the heavy brush and trees and/an abundance of poison oak. Prior to excavating the two borings, a Cat D-8 dozer was utilized to grade an access road along the northside of the canyon and create the drill pad sites. Additional access road/drill pad PACIFIC SOILS ENGINEERING. INC. May 23, 1988 Page 24 Work Order 11044-A construction was programmed. Execution of this work, however, was abandoned due to the heavy brush and poison oak, as well as con- cerns for destroying the natural slope areas. Additional field work should be performed after tentative tract approval. The exploratory pits and borings were logged and sampled by a staff engineer and geologist. Materials encountered were class- ified by visual and tactile examinations. The borings were visual- ly examined by a staff geologist. Logs of Exploratory Pits are presented in Table I. Boring Logs are displayed on Plates Al through A4. Bulk and relatively undisturbed samples were obtained from the exploratory borings to define pertinent soils engineering proper- ties of the on-site materials. Relatively undisturbed samples for detailed testing were obtained by pushing or driving a sampling spoon into the soil/rock stratum. The spoon is a split barrel type having an inside diameter of 2.75 inches, with a tapered driving tip at the lower end. The barrel is lined with a series of 2.5 inch I.D. thin brass rings, each one inch in length. The sampler was driven (0-28 ft. with 2,9004; 28 to 50 ft. with 18004 and greater than 50 feet with 800#), into the stratum below the depth of the boring approximately 12 inches. Blow counts required to advance the spoon sampler were recorded PACIFIC SOILS ENGINEERING, INC. May 23, 1988 Page 25 Work Order 11044-A for each sample obtained and noted as an approximate indication of driving resistance. The central portion of the sample was re- tained for testing. These relatively undisturbed samples in their natural field condition were sealed in airtight containers. Bulk samples were placed in large bags. All samples were then trans- ported to this firm's laboratory for testing. A brief description of the laboratory tests performed are as follows: Moisture -Density Determinations: Laboratory maximum density and optimum moisture content determinations were made in accordance with ASTM Method of Test D-1557-78 utilizing bulk samples obtained from representative soil types to evaluate their compaction char- acteristics. These results are shown in Table I. Unit weight and moisture content of undisturbed samples were deter- mined as a check on the consistency of the various deposits. The results are shown on the accompanying log of borings. Hydrometer Analyses: Hydrometer grain size analyses were per- formed on the minus No. 10 sieve portion of the bulk samples. The results of these analyses were used as an aid in soil classifica- tion and are presented in Table I. Shear Strength: Direct shear tests were performed on undisturbed ring samples and on samples remolded to 90 percent of the labor - PACIFIC sCILs ENGINEERING, INC. May 23, 1988 Page 26 Work Order 11044-A atony maximum density. The samples were saturated under confine- ment for 24 hours and then were tested under various normal loads at a constant rate of strain of 0.025 inches per minute. These results are presented in Table I. ZX23nsive Soil Characteristics: Expansive characteristics were determined for the obtained bulk samples by two methods. In the first method, the samples were tested in accordance with the Expansion Index Test (UBC Standard 29-2). In the second method, samples were remolded to 90 percent of the laboratory maximum den- sity at optimum moisture content and tested from optimum moisture content to saturation under a surcharge load of 650 lbs/sq.ft. These results are given in Table I. Based upon our investigation and analyses, development of the sub- ject property appears feasible from a geologic and soils engineer- ing viewpoint. Much of the proposed plan is compatible with the indicated geologic and soils engineering conditions and may be developed as planned with conventional cut and fill procedures. Geotechnical conditions which would preclude this are indicated below, together with appropriate recommendations intended to re- sult in a safe and stable residential development. The proposed building sites will be free from the detrimental PACIFIC SOILS ENGINEZRINC, INC.

In addition, the proposed building or grading construction will not have an adverse effect on the geologic stability of property out- side of the building sites. A. Geoloa;^ ^^^�i�prations 1. Bedrock materials assigned to the Puente Formation are exposed on and underlie the site, and where relatively unweathered is sufficiently dense to support residential structures and grad- ed fills. Surficial soils should be regraded as indicated below. The on-site earth materials are suitable for.use in compacted fill. 2. Surficial soil deposits, including topsoil, colluvium (Qcol), alluvium (Qal), landslide debris (Qls) and loose fill (af) are compressible and not suitable for the support of engi- neered fills. These materials should be removed to competent, approved bedrock, firm natural ground or firm compacted fill prior to placing compacted fill. The loose fill soils are at least 12 feet thick. Removals within the fill area may approach 15 to 20 feet with an addi- PACIFIC 8011-8 ENOINEERINO, INC. May 23, 1988 Work Order 11044-A Page 28 tional 10 to 15 feet of underlying colluvial and/or alluvial materials. Within the natural canyon areas and bordering flanks, removal depths in the colluvial and alluvial materials are not expected to exceed 15 feet. Elsewhere, removal depths are not anticipated to exceed five (5) to eight (8) feet. Local deeper or shallower removals may be indicated during grading operations. 3. Canyon subdrain systems are recommended beneath compacted fills. All soft colluvium, alluvium and weathered bedrock should be removed in the canyon prior to subdrain install- ation. Subdrains should extend up the canyon and draws to a point no lower than 15 feet below finished grade unless ter- minated at a lower elevation by field evaluation by -the pro- ject geologist and/or soils engineer. Subdrains should be placed in approved firm bedrock materials and constructed as shown on the attached Plate C-1. The existing freeway embankment fill may create difficulties in constructing the lower part of the subdrain system. If an existing canyon subdrain can be located, the proposed system can be tied in to provide an outlet. With this option, the canyon system should be split with the upper portion con- structed to outlet at the toe of the proposed slope. This would require a portion of the subdrain placed in or on com- PACIFIC SOILS ENGINEERING, INC. May 23, 1988 Work Order 11044-A Page 29 pacted fill to outlet. In this case, non -perforated pipe and concrete headwalls at the fill contact should be utilized as directed in the field. The portion of the drain below this can be tied to the existing canyon subdrain. If a system can not be located in the lower canyon area, provisions will be necessary to minimize the effects of groundwater in this area. The upper canyon area will require an upper subdrain as de- scribed above. The lower area will require that proposed fill soils be compacted sufficiently to minimize settlement if the compacted soils were to become saturated. It is anticipated that this can be achieved by compacting the fill soils to a higher degree of relative compaction (i.e. 93 to 95 percent). 4. Bedrock underlying the site is comprised of bedded shales, siltstones and sandstones that display variable attitudes because of drag folding associated with northeasterly trending faults. Based upon the currently available limited geologic data, it is anticipated that the proposed 1-1/2:1 cut slope will exhibit localized adverse geologic structure. Large scale buttress, fills to support large mass planar conditions are not anticipated at this time. Stabilization fills should be constructed with one-half the slope height keyways (15 feet minimum), sloping from toe to heel with a minimum differential of 1 foot. A typical stabilization detail is displayed on Plate C-2. PACIFIC BOILS ENOINEIRPING, INC. May 23, 1988 Work Order 11044-A Page 30 5. Backdrains and lateral outlets are required at the rear of graded buttress fills or stabilization fills in excess of 10 feet in vertical height. A typical detail is shown on Plate C-3. The installation and construction of each backdrainage system should be observed by the soils engineer and/or engi- neering geologist. MINIM . w . . .1 .. . 1. All grading should be done under the observation and testing of the project soils engineer and engineering geologist. 2. Precautions should be taken during the performance of all site clearing, earthwork, and grading to protect the work site from flooding, ponding, or inundation by poor or improper -surface drainage. Temporary provisions should be made during the rainy season to adequately direct surface drainage away from the work site and to approved disposal areas. 3. Prior to grading, the areas within the subject site proposed for development should be stripped and cleared of all existing vegetation, debris and other deleterious materials. These materials should be wasted away from the subject site. 4. In areas to receive compacted fill, all loose fill, loose sur - ficial soils, and soft alluvium/colluvium should be removed to PACIFIC BOILS ENGINEERING, INC. . May 23, 1988 Work Order 11044-A Page 31 firm natural ground, compacted fill or bedrock as approved by the soils engineer or engineering geologist. Removals in the low lying area will involve materials with over optimum moisture content. Excavation of these materials may be difficult with conventional grading equipment. It may be necessary to use a large track mounted backhoe and topload scrapers to accomplish the necessary overexcavation. Removals in the vicinity of the abandoned sewer system will undoubtedly include the removal of this line. special care will be required when working adjacent to the MWD lines. If MWD objects to working in close proximity to their line, con- sidereation should be given to pulling the proposed fill slope back away from the line. The proposed fill slope at the rear of Lots 3 and 4 encroaches into the active portion of the sewer easement. Adequate remo- vals can not be achieved in this area without disturbing the sewer line. Possible alternates might include 1) utilization of a crib block wall system along the toe area to pull the grading away from the easement; or 2) possibly treating the soils in place by grouting to improve the bearing qualities of the soft soils. The crib block wall system may be a more practical and timely option. PACIFIC BOILS ENGINEERING, INC. May 23, 1988 Work Order 11044-A Page 32 Additional field work will be required to address the practi- cality of grouting if this option is considered. 5. In areas to receive fill (after removals, clearing, stripping, overexcavation, etc.) the approved ground surface should be scarified, watered as needed, and compacted to a minimum of 90 percent of the laboratory maximum density in accordance with ASTM Method of Test D-1557-78. The depth of processing should be twelve (12) inches, minimum. 6. Excavated materials which are approved by the soils engineer may be utilized as compacted fill provided that all trash, veg- etation, and other deleterious materials are removed prior to placement. Removals in the low lying area will involve mater- ials with over optimum moisture content. special considera- tions will be required when handling these materials. These considerations may include mixing/blending with drier soils to near optimum moisture or drying the soils to near optimum by turning or aerating the soils. Either option may have an ef- fect on the overall earthwork production until the overexcav- ation of the wet soils are completed. 7. Compacted fill material should be keyed and benched into bed- rock materials or firm natural ground as approved by the soils PACIFIC SOILS EIVOINEERINO, INC. May 23, 198s Work order 11044-A Page 33 engineer and/or engineering geologist, where the natural slope is steeper than 5 -horizontal to 1 -vertical. A typical detail is shown on Plate C-4. s. Any fill required for structural purposes, including retaining wall backfill, should be spread in thin lifts, the moisture content adjusted to near optimum, and the materials rolled and compacted to 90 percent of the laboratory maximum density as described above. Each lift should be treated in a like manner until the desired finished grades are achieved. 9. The County of Los Angeles Building Code (Section 7016 (a)), states: "Fill slopes steeper than 2 horizontal to 1 vertical shall be constructed by placement of soil a sufficient distance beyond the proposed finish slope to allow com- paction equipment to operate at the outer surface limits of the final fill slope surface. The excess fillis to be removed prior to completion of rough grading. construction procedures may be utilized when it is first shown to the satisfaction of the County Engineer that the angle of slope, construction method and other fac- tors will accomplish the intent of this section." a) For fill slopes in excess of 2:1 steepness, the slopes should be overfilled a minimum of three eet (measured horizontally) and the compaction equipment directed uniformly over the entire lift to daylight. Each lift should be treated in a like manner. PACIFIC SOILS ENGINEERING, INC- May 23, 1988 Work Order 11044-A Page 34 compacted fill slopes should be backrolled during placement at intervals not exceeding four feet in vertical height. Care should be taken to construct the slope in a workmanlike manner so that it is positioned at its proper bearing and slope ratio geometry to prevent "tack -on laminations" and "wedge add-ons." Any add-on correction to a fill slope will require overfilling the affected area in mini- mum equipment width compacted lifts which must be benched into the existing fill prism. Excess mater- . ial should be removed at the completion of rough grading. cut and fill slopes are planned at ratios as steep as 1-1/2 horizontal to 1 vertical. Fill slopes at this ratio will require overbuilding and trimming back to proposed finish grades. Within the interior of the tract, this can be achieved by trimming the overfill down to the pads and placing as compacted fill. The slope area descending from Lots 1 thru 6 will be more difficult because of limited access and working area. The grading contractor might consider overexcavating this area to accommodate the excess trim spoils. PACIFIC SOILS ENOINEBRINO, INC. May 23, 1988 Work Order 11044-A Page 35 b) The contractor should be aware that care must be taken to avoid spillage of loose material down the face of the slopes during grading and during drain- age terrace and downdrain construction. Fine grad- ing operations for benches and downdrains should not deposit loose trimmed soils on the finished slope surfaces. These materials should be removed from slope areas. This item applies to cut slopes as well as fill slopes. c) Seeding and planting of the slopes should be planned to achieve, as rapidly as possible, a well esta- blished and deep-rooted vegetation requiring minimal watering. The type of vegetation and watering sche- dule should be determined by a landscape architect familiar with hillside maintenance. The watering requirements should be reviewed by this firm. The homeowner should be made aware of the DOteTtial— problems which may develoR when drainage altered - through construction of retaining walls,swimmina R0010,.paved walkways and patios.

Imported materials should possess similar or lesser expansion potential. THE SOILS ENGINEER SHOULD BE NOTIFIED AT LEAST 48 HOURS IN ADVANCE IN ORDER TO SAMPLE, TEST, AND APPROVE OR DISAPPROVE MATERIALS FROM PROPOSED BORROW SITES. NO IMPORT MATERIAL SHOULD BE DELIVERED FOR USE ON THE SITE WITHOUT THE PRIOR APPROVAL OF THE SOILS ENGINEER. 11. Fill should be tested at the time of placement to ascertain that the required compaction is achieved. The minimum basis of testing should be one (1) test per two (2) feet of depth or each 1000 cubic yards of fill placed. At least 1/2 the re- quired tests should be made at the location of the final fill slope, except that not more than one such test need be made PACIFIC SOILS ENGINEERING, INC.

In view of the varied geotechnical conditions on-site, field observations by qualified personnel are necessary in order to achieve a well engineered and designed development. These include continuous testing and observations by field techni- cians, and periodic observations by the tract geologist and soils engineer. 13. The results of the observation and testing of all earthwork should be presented in a soils engineering report following the completion of earthwork and grading. 1 . �� •I1 1.

For preliminary purposes, the following criteria for foundation design, assuming "high" expansion potential, would be as follows: a) Footings should be embedded a minimum of 24 -inches for 1 -story and 2 -story structures. Embedment depth should be measured from the lowest adjacent grade, except for inter- ior footings which may be measured from the finish surface of the adjacent slab. b) Minimum reinforcement for footings should include four No. 4 bars, two (2) top and two (2) bottom. c) Minimum reinforcement for concrete slabs should include No. 3 bars spaced at 18 inches on center each way. The footings should be doweled to the slab with No. 3 bars placed 36 inches on center. The dowels should extend into the slab at alternating embedment depths of 18 inches and 36 inches. d) Slabs -on -grade in living areas shall be placed on four inches of sand, two above and two below a 6 -mil ,visqueen n type moisture barrier. PACIFIC SOILS ENGINEERING, INC. May 23, 1988 Work Order 11044-A Page 39 e) A designed bond beam should be placed across garage door openings and tied into the footings. Minimum reinforce- ment should consist of four (4) No. 4 bars, two (2) top and two (2) bottom. f) The soil in the foundation excavations and subgrade for interior concrete slabs shall be pre -moistened prior to placing concrete. g) Materials from footing excavations should not be spread in slab -on -grade areas unless it is compacted and tested. Verification of expansive soil conditions will be made as final grades are achieved. Final footing and slab configura- tion and reinforcement recommendations will be provided pend- ing verification of expansive soil characteristics at the conclusion of the grading operations. 4. For design purposes a maximum allowable bearing capacity of 1500 lbs/sq.ft. at a minimum recommended embedment depth into firm natural ground or approved compacted fill may be used for continuous footings and square pad foundations. 5. In designing to resist horizontal loads, lateral bearing of 200 lbs/sq.ft. per foot of embedment, to the maximum allowable PACIFIC SOILS ENOINEEAINO. INC. May 23, 1988 Work Order 11044-A Page 40 value, and a friction factor of 0.4 may be used where slabs or footings are cast against firm natural ground or compacted fill. Friction and lateral resistance may be combined provided the lateral bearing resistance utilized does not exceed 2/3 of the allowable lateral bearing. The above values may be increased 1/3 for resisting seismic or wind forces. 6. Based upon the anticipated foundation loadings, and consolida- tion characteristics of the existing materials and compacted fill, settlement should be minimal with no detrimental effects to the proposed construction providing recommendations con- tained herein are incorporated into the design and construc- tion. 7. All roof, pad and slope drainage should be collected and di- rected away from the proposed structures to approved disposal areas. It is important that drainage be directed away from foundations. The recommended drainage patterns should be established at time of fine grading and maintained throughout the life of the structure. Pad drainage should not be allowed to run over slopes. PACIFIC BOILS ENGINEERING, INC. May 23, 1988 Work Order 11044-A Page 41 1. Cut slopes with a gradient of 1-1/2 to 1 or flatter, which exhibit favorable geologic conditions, may be considered adequately stable if constructed per the applicable Los Angeles Building Code requirements. 2. Fill slopes are programmed at slope ratios of 1-1/2 to I. Slope stability calculations for 1-1/2 to 1 fill slopes are shown on Plate B-1; the calculations indicate that 1-1/2:1 slopes will be adequate stable to heights of approximately 52 feet. Slope stability calculations for 1-3/4:1 fill slopes are shown on Plate B-2; 1-3/4:1 slopes should be considered adequately stable to heights of approximately 66 feet. Slopes of 2:1 and flatter may be considered adequate'if constructed per the applicable Building Code requirements. 3. It is anticipated that all or portions of the cut slope at the rear of Lots 7-18 may require rehabilitation with stabil- ization fill sections to mitigate locally adverse geologic structure. Construction of stabilization fill devices will create fill slope conditions. The height of slope through this area varies from 50 to 75 feet. Accompanying stability calculations indicates that if these slopes are stabilized, they should be reconstructed at a slope ratio of 1-3/4 to 1 PACIFIC SOILS ENGINEERING, INC. May 23, 1988 Work order 11044-A Page 42 or 2 to 1. The slope as designed at 1-1/2 to 1 could be con- structed if a higher degree of compaction was required for the fill. 4. The cut portions of the sideyard slopes on Lots 9-15 and 22 may expose locally adverse geologic. If necessary, the side slopes should be re -built as minimum equipment width (15 feet) stabilization fill sections. Final determination for the need for stabilization of these and possibly other slopes should be made during grading when detailed geologic conditions are observable. A typical sta- bilization fill detail is shown on Plate C-2. 5. Fill -over -cut slopes are indicated on the enclosed plan. These slopes may be safely constructed by excavating a minimum equipment width keyway into firm bedrock or approved founda- tion materials (see Plate C-4). The keyway should be tilted inward and must be observed by the engineering geologist, soils engineer or his representative prior to fill placement. If adverse geologic conditions are encountered, the cut por- tion of the slope should be overexcavated and replaced as a minimum equipment width stabilization fill section. 6. Laboratory test results indicate that on-site materials, to be PACIFIC SOILS ENGINEEAINOP INC. May 23, 1988 Work Order 11044-A Page 43 used as compacted fill, can be expected to have cohesion in excess of 250 lbs/sq.ft. Surficial slope stability analyses for 1-1/2 to 1 fill slopes presented on Plate B-3, indicate the proposed fill slopes will have an adequate margin of safety. Flatter slopes will have a higher factor of safety. The findings and recommendations contained in this report are based upon the specific excavations and observations as noted. The materials immediately adjacent to or beneath those observed may have different characteristics, and no representations are made as to the quality or extent of materials not observed. This report is subject to review by the controlling authorities for the project. Respectfully submitted, PACIFIC SOILS ENGINEERING, B DANIEL T vice Pri Reg.

June 13, 1989 Work Order 11044-A Gentlemen: Page 2 This addendum report is in response to the Reference 7 Geotech- nical Engineering Review Sheet. The review sheet requests additional information prior to tentative map approval. The review sheet is based upon review of the Reference 5 Addendum Report and an earlier Preliminary Geotechnical Evaluation (Reference 1). The tentative map has been approved from a geological standpoint as indicated in the Reference 2 and 6 Engineering Geology Review Sheets. The items of concern from the Reference 7 review sheet are presented below and then followed with this firms response. Item: - "1. All cut and fill slopes steeper than 2:1 must be analyzed for stability." Response: This firms Reference 1 Preliminary Report contained stability calculations for proposed fill slopes at slope ratios of 1.5:1 and 1.75:1. Based upon these calculations, it was concluded that 1.5:1 and 1.75:1 fill slopes would be stable to heights of 52 feet and 66 feet respectively when construct- ed of fill materials compacted to 90 percent of the labora- tory maximum density. PACIFIC SOILS ENGINEERING. INC. June 13, 1989 Work Order 11044-A Page 3 The current tentative map displays fill slopes at 1.5:1 slope gradients. The highest fill slope proposed is about 50 feet high at the rear of Lots 4 and 5. This slope is within the limits of the previously submitted calculations (see Plate B-1, Reference 1) and is therefore considered stable as programmed. Cut slopes are displayed on the tentative map at ratios of 1.5:1 which range in height from a few feet to 90 feet. The tentative map displays a variable height cut slope bordering the rear of Lots 7-16 at a slope ratio of 1.5:1. The slope varies in height from SO to 75 feet. It is this firms opinion, based upon the geotechnical conditions observed during mass grading of the northerly adjacent property (Tract 39679) and encountered on-site in the exploratory test pits and borings, that the bedrock structure is discontinuous and variable due to drag folding associated with northeasterly trending faults. As a result, large scale buttress fills are not anticipated. 'It is anticipated that all or portions of the cut slope may require rehabilitation with stabilization fill sections to mitigate locally adverse geologic structure. If localized areas of adverse geologic structure are encount ered, the slope can be effectively rehabilitated as a one- half the slope height stabilization fill section. Due to the PACIFIC SOILS ENOINUMP1INOw INC. June 13, 1989 Work Order 11044-A Page 4 fill height requirements, this would necessitate reconstruct- ion of the slope with fill soils compacted to 95 percent of the laboratory maximum density or redesign of the slope at 2:1 gradients. This latter condition would reduce the flat pad area displayed on the tentative map. Accompanying this transmittal are stability calculations for 1.5:1 fill slopes utilizing shear strength parameters for fill soils compacted to 95 percent of the laboratory maximum density. The calculations indicate the proposed slopes can be effectively rebuilt as compacted fill slopes. A compound 1.5:1 to 5:1 slope is shown at the rear of Lots 17 and 18. Comments addressing the compound slope were'present- ed in the Reference 5 report. as follows: Those comments are reiterated "Cross-section A -A' has been drawn through the high cut slope area at the rear of Lots 17 and 18. Geologic data from borings has been superimposed on the cross-section. The cross-section depicts a 90± feet 1-1/2:1 slope with a superjacent 70± feet high 5:1 slope. The proposed cut should remove the landslide debris from the proposed cut face. Based upon the currently available limited geologic data, it is anticipated that the proposed 1-1/2:1 cut slope may exhibit localized adverse geologic structure. Large scale buttress fills are not anticipated at this time. The slope could be effectively rehabilitated with a one-half the slope height stabilization section. PACIFIC SOILS ENGINNSRINO, INC. June 13, 1989 Work Order 11044-A Page 5 The slope is currently proposed at a 1-1/2:1 slope gradient. Slope stability calculations presented in the Reference 1 Preliminary Geotechnical Report indicate maximum slope heights on the order of 52 feet for fill slopes constructed at 1-1/2:1 slope gradients. If the slope requires stabilization it will be necessary to reconstruct the 90 ft. high slope at a 2:1 gradient or con- struct a 50 ft. high 1-1/2:1 stabilization fill with the slope area above steepened to approximately 4-1/2:1. Either alternative would be satisfactory. Engineering Cross -Section A -A' shows the relationship of the proposed finished grading and stabilization fill section with a 50 foot high 1-1/2:1 fill slope and 4-1/2:1 layback. Calculations are presented herein for the proposed stabilization fill section. The fill slope, as proposed has a factor of safety of 1.52." Utilization of fill soils compacted to 95 percent relative compaction will allow construction of the slope area at the rear of Lots 17 and 18 essentially as shown on the plan. It would be necessary to steepen the upper portion of the cut to 4.8:1 or 4.9:1 and drop the 1.5:1 portion to 80± feet in height. The design should be detailed at the time of 40 -scale grading plan preparation. The proposed grading displayed on the tentative map is considered feasible from a geotechnical viewpoint provided recommendations herein and contained in the References 1 and 5 reports are incorporated into design and construction. The proposed fill slope at the rear of Lots 1 through 5 is considered stable as programmed. PACIFIC SOILS ENGINEERING, INC. W June 13, 1989 Work Order 11044-A Page 6 The cut slope at the rear of Lots 7-16 can be stabilized with a one-half the slope height stabilization fill section. The stabilization fill will be constructed at a slope gradient of 1.5:1 with fill soils compacted to 95 percent of the laboratory maximum density. The lower portion of the cut slope at the rear of Lots 17 and 18 can be stabilized with a one-half the slope height stabilization fill section. The stabilization fill will be constructed at a slope gradient of 1.5:1 with fill soils compacted to 95 percent of the laboratory maximum density. The upper portion of the cut will be graded at approximately 4.8:1 to 4.9:1 to reduce the height of the 1.5:1 slope to 80 feet. This can be accomplished during the detailed grading plan preparation. The cut slope located at the rear of Lots 19 and 20 is considered to exhibit favorable geologic structure and as such, is considered to be grossly stable. Item: 112. All natural and cut slopes that have daylighted bedding planes must be analyzed for stability. Please submit stability calculations for static and seismic analyses and geotechnical cross-sections." PACIFIC SOILS SNOINERRINO. INC. June 13, 1989 Work Order 11044-A Response: Page 7 No natural slopes are anticipated to possess daylighted bedding conditions at this time. The cut slope at the rear of Lots 7 through 16 has been previously discussed along with the slope area at the rear of Lots 18 and 19. The slopes do not possess large scale planer instabilities and as such do not require designed buttress fills. Cut slopes, which area anticipated to exhibit locally daylighted conditions, will be effectively rehabilitated with one-half the slope height stabilization fill sections. Cross-sections have been previously presented in the Reference 5 Addendum Report. This report is considered to adequately respond to concerns expressed in the Geotechnical Engineering Review Sheets.' It is this firms opinion that the proposed grading is feasible from a geotechnical viewpoint. The proposed building sites will be free from the detrimental affects associated with landsliding, settlement and slippage provided the grading construction is performed in an acceptable manner conforming to building code requirements of the County of Los Angeles and the recommendations of this firm contained here - PACIFIC SOILS UNGINESPING. INC. June 13, 1989 Work order 11044-A Page 8 in. In addition, the proposed building or grading construction will not have an adverse effect on the geologic stability of property outside of the building sites. This report is subject to review by the controlling authorities for the subject project. If you have any questions, please contact the undersigned at (213)-775-6771.

Certificates of such insurance, approved by the City Manager and City Attorney, shall be filed with the City Clerk within ten (10) days after the execution of the contract. Contractor shall immediately inform City of any cancellation, withdrawal and/or change of any such insurance. III. SCOPE OF WORK A. Standard of Performance The primary objective of street sweeping is to pickup all leaves, paper, dirt, rocks, cans and/or other debris to ensure free flow of water in the gutter and to maintain streets in a state of cleanliness. The Engineer or his 2 designee will make the final determination as to whether the work has been satisfactorily completed and to order the Contractor to re -sweep or re -do areas not swept or done in a satisfactory manner. B. Sweeping The Contractor shall sweep and/or clean all public streets and alleys as specified herein and as included within the limits of the area shown on the plans. Gutters of all paved streets and raised medians shall be swept as specified in the Standard of Performance. Sweeping shall normally consist of a single pass at not more than 6 miles per hour over an area. Additional passes shall be made if necessary in problem areas where silt, leaves, debris or other conditions warrant special attention. Water shall be used while sweeping to minimize dust. The word sweeping shall define an operation and the method shall not be limited to the use of a power broom street sweeper. In the event that the results of a sweeping are considered unsatisfactory by the Engineer or his designee, the Contractor shall sweep or clean the unsatisfactory area again at no cost to the City, within two (2) calendar days without interruption in the regular sweeping schedule. Curbed areas that cannot be swept with power sweeping equipment, such as but not limited to narrow cul-de-sacs, median noses and portions of left turn pockets, shall be hand cleaned to comply with the Standard of Performance. B. Disposal of Refuse and Debris All debris and refuse collected by the Contractor shall become his property from and after the time of sweeping. The Contractor shall dispose of all refuse and debris collected during sweeping operations, at no additional cost to the City, by hauling same to a legally established area for the disposal of solid waste. When storage of refuse and debris is necessary prior to disposal, the Contractor shall locate and arrange for use of a temporary storage site off the road right of way. The Contractor shall remove all refuse and debris from temporary storage sites before 5:00 p.m. of the day deposited. The Contractor shall, when removing refuse and debris from temporary storage sites, remove and dispose of any waste material or objects left there by others. C. Water The Contractor shall furnish all water necessary for sweeping operations in accordance with Section III A, Sweeping. 7 D. Inspection Periodic inspection of the work will be made by the Engineer or his designee to assure compliance with the Specifications. E. Additional Sweeping The Contractor is to provide additional sweeping of any street(s) and alley(s) within the area shown on the Plans at any time ordered by the Engineer or his designee. The Contractor will be compensated for such additional sweeping at the contract unit price per curb -mile in effect at the time. The method of payment will be determined by the Engineer or his designee. No allowance will be made for travel time on additional sweeps, but the minimum curb mileage to be compensated will be sixteen (16) and the minimum hours will be four (4). The need for additional sweeping may be because of storm, f ire, flood, parade, public gathering, riot or other natural or unanticipated occurrence affecting the cleanliness of the streets and highways. The additional sweeping may be in lieu of or in addition to the regularly scheduled sweeping as ordered by the Engineering or his designee. Additional sweeping will normally be confined to sweeping the curb lane. If, however, additional sweeping requires the total width of the street(s) to be swept, then compensation will be at the contract unit price per curb - mile. All sweeping shall be done with sufficient passes to achieve the results set forth in the Standard of Performance. Minimum payment will be for sixteen (16) curb miles. Notwithstanding the above, the City has the option on additional sweeps to compensate the Contractor on an hourly basis where it is difficult to determine curb miles swept in a non -routine manner. In these cases, the hourly rate paid by the City to the Contractor shall be equal to four times the contract unit price per curb mile. Minimum payment will be four (4) hours. F. Schedule Disruptions During the contract time, the Contractor shall sweep the designated public streets and alleys at least once each week, including all curbed medians, in accordance with a schedule to be approved by the Engineer or his designee. When, in the opinion of the Engineer, inclement weather prevents adherence to the regular sweeping schedule for 2 days or less in a given week, the Engineer or his designee may require the sweeping areas so affected to be swept prior to the next sweeping schedule. Any such required sweeping made necessary by inclement weather shall meet the requirements of the Standard of Performance and shall be performed by the Contractor at the normal curb -mile price in effect at the time and will not be considered additional sweeping as defined in Section III -E, Additional Sweeping. When any holiday or observance as specified in the Government Code of the State of California occurs on a regularly scheduled sweeping day, and said sweeping area is not swept in observance of said holiday, the subject sweeping area shall, when ordered by the Engineer or his designee, be swept within two (2) working days of the regularly scheduled sweeping day without interruption in the regular sweeping schedule. Any such requested sweeping shall meet the requirements of the Standard of Performance and shall be performed by the Contractor at the curb mile price in effect at the time and shall not be considered additional sweeping. In the event the Contractor is prevented from completing the sweeping as provided in the approved schedule because of reasons other than inclement weather or holidays, it will be required to complete the sweeping services so deferred within two (2) calendar days without interruption in the regular sweeping schedule. G. Added and Deleted Streets It is the intent of this contract to provide for the weekly sweeping of all curbed streets and improved alleys within the incorporated area shown on the plans. As streets and alleys are improved or annexed, they will be added to the weekly sweeping schedule. Compensation to the Contractor will be based on curb miles added multiplied by the current contract unit price. Streets and alleys initially included in the schedule that are vacated by order of the City Council will be deleted from the weekly schedule and the affected curb mileage deducted from the contract quantities. Additions and/or deletions of curb mileage may affect the approved schedule and appropriate adjustments will be allowed subject to approval by the Engineer or his designee. H. Utilities The Contractor shall recognize the rights of utility companies within the public right of way and their need to maintain and repair their facilities. The Contractor shall exercise due and proper care to prevent damage to utility facilities and to adjust schedules when utility t7 operations prevent the Contractor from sweeping during a specified time frame. No additional compensation will be allowed for complying with these requirements. I. Construction Schedule and Commencement of Work A complete schedule of weekly sweeping shall be submitted to the Engineer or his designee for approval prior to any work being done under this contact. The schedule shall include the curb miles of streets, alleys and medians to be swept daily as well as the daily starting time.
