Rdlandr. CA 92373.0306 Thank you for the opportunity to respond to the above -referenced project. Please note that Southern California Gas Company has facilities in the area where the above named project is proposed. Gas service to the project could be provided without any significant impact on the environment. The service would be in accordance with the Company's policies and extension rules on file with the California Public Utilities Commission at the time contractual arrangements are made. You should be aware that this letter is not to be interpreted as a contractual commitment to serve the proposed project, but only as an informational service. The availability of natural gas service, as set forth in this letter, is based upon present conditions of gas supply and regulatory policies. As a public utility, The Southern California Gas Company is under the jurisdiction of the California Public Utilities Commission. We can also be affected by actions of federal regulatory agencies. Should these agencies take any action, which affects gas supply, or the conditions under which service is available, gas service will be provided in accordance with revised conditions - Typical demand use for a. Residential (System Area Average/Use Per Meter) Yearly Single Family 799 therms/year dwelling unit Multi -Family 4 or less units 482 therms/year dwelling unit Multi -Family 5 or more units 483 thermslyear dwelling unit These averages are based on total gas consumption in residential units served by Southern California Gas Company, and it should not be implied that any particular home, apartment or tract of homes will use these amounts of energy. 2.0-2 1 09-15-00 17:29 City of LaQuinta Comm.Dev.Dept ID- 760 777 1233 P•02 b. Commercial Due to the fad that construction varies so widely (a glass building vs. a heavily insulated building) and there is such a wide variation in types of materials and equipment used, a typical demand figure is not available for this type of construction. Calculations would need to be made after the building has been designed. We have Demand Side Management programs available to commercialfindustrial customers to provide assistance in selecting the most effective applications of energy conservation techniques for a particular project. If you desire further information on any of our energy conservation programs, please contact our Commercial/industrial Support Center at 1 -800 -GAS -2000.

We are concerned that this report does not adequately addresses water supply and mitigation Dissues for this project. We have commented on these concerns in the enclosed Attachment A. r, If you have any questions please call Joe Cook, planning engineer, extension 292. Yours very truly, Ily Enclosure/l/as cc: Michael Brown (with enclosure) Impact Sciences, Inc. 30343 Canwood Street, Suite 201 Agoura Hills, California 91301 .TECJI\eng\sw\sep\ccofdesert /s/ Tom LeVY Tom Levy General Manager -Chief Engineer RNMI COACHELLA VALLEY WATER DISTRICT ATTACHMENT A I. Page 2.0-9 under the heading, 4.3, Hydrology and Water Quality, states, "Adequate supplies of water could be provided to the project without impacting the quality of surface or groundwater." This is followed with, "No mitigation measures required." This section does not appropriately address the question on a typical environmental checklist that asks, "Would the project substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or lowering groundwater table level ... T' We consider this answer is inadequate for a development of the size. The groundwater basin in the Coachella Valley is in a state of overdraft and this development will add incrementally to this problem. We encourage the applicant to include mitigation measures which will prove effective in reducing the demand for water for this development. Such mitigation measures may include low water use landscaping, limiting the size of water features and water conserving irrigation, practices. 2. Page 2.0-20, 4. 10, Utilities and Service Systems, to be revised to address that there is an extensive underground irrigation water distribution system within the project area which has 2 not been addressed in this section. Provisions must be made to improve, relocate or abandon existing irrigation facilities. 3. Page 2.0-20, 4. 10, Utilities and Service Systems. The report states "The water demands of the project would be assessed during the district's Senate Bill 901 (SB 901) review." The district has addressed SB 901 more specifically in item 10 of this attachment. 4. Page 3.0-14, Infrastructure Plan, under the subheading of Potable Water. The first and second sentences to be revised as follows: Potable water will be provided to the project area by the district through a series of 18 -inch water lines . The 18 -inch water lines are proposed 4 for Avenue 52, Avenue 54, Jefferson Street and Monroe Street, although the actual water improvements would be determined based upon a review of the development plans by the district. 5. Page 3.0-14, Infrastructure Plan, under the subheading Irrigation Water, to be revised as follows: Water for irrigation is to be provided to the project vicinity by the district via the Coachella Canal which is located along the northwestern boundary of the project site. There are existing irrigation delivery laterals within the project site which will need to be replaced or relocated. These irrigation laterals are owned by the Bureau of Reclamation and are operated by the district. 6. Figure 3.0-5, Proposed Master Plan of Infrastructure, to be revised to show two domestic water pressure zones within the proposed development. The developer's engineer 6 shall work with the district's domestic water unit to confirm the design of the domestic water system. 2.0-6 7. Page 4.3-5, Groundwater Occurrence and Quality, third sentence to be revised to reflect the following: Groundwater quality below 500 feet in depth is variable in the vicinity of the project. A well near the project that pumps at depths of 740 to 1,048 feet has produced groundwater with naturally occurring mineral levels that exceed water standards. Groundwater quality is generally poor to marginal at a depth of less than 200 feet below the ground surface. 7 8. Page 4.3-6, On-site Water Ouality, to be revised to reflect the following: The district recommends that the association of water quality at the site and water quality at Well Nos. 6723 and 6724 be deleted from the text. Some wells in this area have produced 8 unacceptable levels of minerals. Conclusions about groundwater quality should only be made after water samples are tested. 9. Page 4.10-2, City of La Ouinta Water System, second paragraph, first sentence to read as follows: Potable water is stored in seven reservoirs that serve five pressure zones in the city. 10. Page 4.10-3 and 4, Senate Bill 901 and Water Supply Planning, last paragraph. The report states that "Senate Bill 901 directs water agencies to provide such (water basin water plan) information in response to a Notice of Preparation (NOP)...," and "The Coachella Valley Water District did not respond to the NOP." We are in disagreement with this statement and regard that an error has been made in the procedures of SB 901. On page 6 of SB 901, it states the following: The city or county, at the time it submits a notice of preparation, shall request each public water system identified pursuant to subdivision (c) to assess whether the project described in subdivision (a) or (b) was included as part of the most recently adopted urban water management plan adopted pursuant to Part 1.6 (commencing with Section 10610). The district does not recognize a notice of preparation as being equivalent to proper notification by the City of La Quinta to begin a water assessment report in connection with SB 901. It is not the role of the district to make the determination if a development is subject to SB 901. The district receives dozens of notice of preparations each year, the majority of which do not pertain to the conditions of SB 901. The district will assess this project in accordance with SB 901 when it has.been properly notified and provided sufficient information to determine water demands for the project. 0 10 11. Page 4.10-4, Wastewater Collection and Treatment, second paragraph, second sentence, to reflect the following: The Mid -Valley Water Reclamation Plant has a current capacity ofI 11 7 -million gallons per day. 12. Page 4.10-8, Water Supply and Distribution, under the subheading Qperational Impacts, first and second sentences, to be revised as follows: Potable water would be provided to the project by the district through a system of wells, reservoirs and water transmission lines. The 12 water transmission and distribution lines will be funded and installed by the developer subject to the district's approval. 2.0-7 JEC J1\mg\sw\sep\cco£desert 2.0 Response to Comments 2. Letter from Coachella Valley Water District, Tom Levy, dated September 29, 2000 Response 1 The issue of water supply to the proposed project, including groundwater, is discussed in Section 4.10 Utilities and Service Systems of the EIR. The condition of the groundwater basin is discussed on pages 4.10-1 and 4.10-2 of the EIR. Mitigation measure 4.10-1 requires the project developers to consult with the Coachella Valley Water District (CVWD) to develop water conservation measures for both landscaping/ irrigation requirements and plumbing controls. Consistent with CVWD's existing and future water conservation plans, policies and standards, the City will require that the developers implement the water conservation measures that are devised from the consultations with CVWD, and will require compliance with the City's water conservation programs and ordinance, to the extent applicable. This would ensure that any use of groundwater by the project complies with all existing plans and projections of the CVWD. Therefore no unavoidable significant impacts would occur. Response 2 The text in Sections 2.0 and 4.10 of the EIR has been revised to indicate that there is an extensive underground irrigation water distribution system within the project area which will need to be improved, relocated or abandoned in accordance with CVWD standards. Response 3 The text in Sections 2.0 and 4.10 of the EIR has been revised to delete the reference to SB 901 review. L SB 901 (now codified as Water Code section 10910-10915) requires consultation between a city or county r and affected water agencies to ensure that adequate water supplies would be available for new projects. LIn the case of this project, estimates of the project's water demand were made and CVWD staff were contacted by the EIR consultant during the Draft EIR preparation stage to determine whether adequate supplies of both potable and non -potable are available for the project. The EIR consultant was informed that the existing potable and non -potable water supplies are adequate to serve the proposed project without causing any significant impacts. Specific water conservation measures for both landscaping and irrigation, and plumbing controls may be identified and placed as conditions on the connection of the project to the CVWD's facilities. Compliance with CVWD water conservation measures is required by mitigation measure 4.10-1. Therefore, the City has met the intent of SB 901 rthrough direct consultation with CVWD staff. L 2.0-8 Country Club of the Desert EIR Final - November 2000 2.0 Response to Comments Response 4 The text in Sections 3.0 and 4.10 of the EIR has been revised to indicate that potable water would be provided to the project area by the CVWD through a series of 18 -inch water lines. The 18 -inch water lines are proposed to be installed in Avenue 52, Avenue 54, and Monroe Street. In addition, the existing 12 -inch water line located in Jefferson Street is proposed to be upsized to 18 inches. The actual water improvements would be determined based upon a review of the final site plan by the CVWD. Responses The text in Sections 3.0 and 4.10 of the EIR has been revised to indicate that the existing irrigation delivery laterals within the project site would need to be replaced or relocated to serve the project. These irrigation laterals are owned by the Bureau of Reclamation and are operated by the CVWD. Response 6 The text in Sections 3.0 and 4.10 of the EIR has been revised to indicate that there would be two domestic water pressure zones within the project site and that the developers would be required to work with the CVWD's domestic water unit to confirm the design of the domestic water system. Response 7 The text in Section 4.3 of the EIR has been revised to indicate that groundwater quality below 500 feet in depth is variable in the vicinity of the project site. A well near the project site that pumps at depths of 740 to 1,048 feet has produced groundwater with naturally occurring mineral levels that exceed adopted water standards. Groundwater quality is generally poor to marginal at a depth of less than 200 feet below the ground surface. Response The identified text in Section 4.3 of the EIR has been deleted as requested. Response The text in Section 4.10 of the EIR has been revised to indicate that potable water is stored in seven reservoirs that serve five pressure zones in the city. 1 2.0-9 Country Club of the Desert EIR r Final - November 2000 2.0 Response to Comments Response 10 See response 3, above.

The page numbers shown on the following pages may be different than those of the Draft EIR due to the number of revisions in a given section. None of the revisions that have been incorporated into the Final EIR affect the analysis completed, nor the conclusions presented in the Draft EIR regarding the environmental impact of the proposed project. 3.0-1 Country Club of the Desert EIR Final — November 2000 2.0 Summary Table 2.0-1 (continued) Summary of Project Impacts, Mitigation Measures, and Residual Impacts' Residual Project Impacts Recommended Mitigation Measures Impacts 4.9 PUBLIC SERVICES (continued) Based on the student generation factors used by the Coachella Valley Unified School District (CVUSD), the proposed 819 residential units could generate up to approximately 549 elementary school students, 147 middle school students, and 328 high school students. Since the permanent capacity of the facilities is presently exceeded,. the potential generation of this many additional students Is considered a significant impact. 4.10 UTILITIES AND SERVICE SYSTEMS During the construction phases of development, non -potable water would. be used to suppress dust generated by earthmoving activities, the operation of vehicles on dirt surfaces, and exposed dirt surfaces. This water would be obtained from the Coachella Canal. According to CVWD staff, the existing non -potable water supplies are adequate to serve the proposed project without causing any significant impacts. The potable water demand of the proposed project is estimated to be approximately 479 acre-feet per year. Demand for non -potable irrigation water is estimated to be 5,250 acre- feet per year. According to CVWD staff, the existing potable and non -potable water supplies are adequate to serve the proposed project without causing any significant impacts. Water well sites would be provided on the project site in accordance with CVWD standards to provide water for the project. 44ie water demand -of th&-project wou]d-be -assessed. during--the-CVXJ D's SEi-901--review�peeif-ic Hdw_ ey_Qr,:specific water conservation measures for both landscaping and irrigation, and plumbing controls may be identified and placed as conditions on the connection of the project to the CVWD's facilities. 4.9-8.

The attended schools shall be established by the' Coachella Valley Unified School District. None recommended or required. 4.10-1. To ensure that future land uses do not include activities which unnecessarily waste water or which consume exceptional amounts of water, the City will direct the project developers to consult with the CVWD to develop appropriate water conservation measures for both landscaping/irrigation requirements and plumbing controls. Consistent with CVWD's existing and future water conservation plans, policies and standards, the City will require that the developers implement the water conservation measures that are devised from the consultations with CVWD, and will require compliance with the City's water conservation programs and ordinance, to the extent applicable. Not Significant Not Significant 2.0-20 Country Club of the Desert Final EIR November 2000 3.0 Project Description Infrastructure Plan All necessary utilities and infrastructure services are currently available in the project vicinity. The major infrastructure components proposed to be installed as part of the project are illustrated in Figure 3.0-5 and described below. Potable Water Potable water is provided to the project vicinity by the Coachella Valley Water District (CVWD) through an existing 12 -inch water main located in Jefferson Street. A series of 18 -inch water lines are proposed to be installed in Avenue 52, Avenue 54, and Monroe Street as part of the project. In addition, --- -- — the existing 12 -inch water line located in Jefferson Street_iS proposed to be upsized to 18 inches., ::,{-I;rtr The actual water improvements would be determined based upon a review of the final site plan by the CVWD. Per CVWD standards, a water well site would be required within the project site for every 70 acres of developed property. Discussion with the CVWD would occur following project approval to determine the actual number and locations of on-site wells. Irrigation Water Water for irrigation is also provided to the project vicinity by the CVWD via the Coachella Canal, which is located along the northwestern boundary of the project site. There are Existing existing irrigation delivery lines within the project site that projeei-srtewOUld need to be replaced or relocated. These irrigation lines are owned bv the Bureau of Reclamation and are operated by the CVWD. Wastewater Wastewater generated within the project vicinity is collected and treated by the CVWD at the Mid - Valley Water Reclamation Plant. An existing 18 -inch force main is located in Jefferson Street and a portion of Avenue 54. A wastewater collection system is proposed to be constructed within the project site with one or two connection points to the existing force main. Sewer lift stations and force mains would be required at the collection points within the project site. Storm Drainage The control of local storm water drainage is under the jurisdiction of the City of La Quinta. As proposed, runoff would be collected via private storm drains and conveyed to numerous, localized retention basins within the project site. For the most part, these retention basins would be constructed in conjunction with the golf course water features. 3.0-14 Country Club of the Desert Final EIR November 2000 4.3 Hydrology and Water Quality observed around the perimeter of the pond and may have been used to line the pond. Furthermore, stockpiles of end -dumped fill material, exist generally along the northern side of Avenue 54, and trash and rubble exist along Avenue 53. The Coachella Canal, a concrete -lined irrigation canal, is located to the adjacent to the northwest edge of the site. Historical Uses of the Site Historical aerial photographs of the project site were reviewed at the Coachella Valley Water District office located in Coachella, California. Aerial photographs from 1949, 1953, 1973, and 1982 were examined to evaluate the historical use of the site. In the aerial photograph dated February 15, 1949, the site is undeveloped vacant land with the exception of agricultural use in the southwestern comer of the site near' the intersection of Jefferson Avenue and Avenue 54. Jefferson Avenue was a paved road at that time, and Avenues 52, 53, and 54 and Monroe and Madison Streets were unpaved. The Coachella Canal was also present to the northwest of the site. The aerial photograph of September 20, 1953 shows that portions of the site were used for agricultural purposes; however, due to the poor resolution of the photograph, specific details of the site were difficult to discern. On April 27, 1973, the majority of the site was used for agricultural purposes. The northwestern portion of the site, north of Avenue 53, appears to have been vacant undeveloped land. Several ponds, possibly to store irrigation water, were also present on the site in 1973. Finally, the aerial photograph dated September, 1982 shows the site as primarily being used for agricultural purposes. Portions of the site appear to be vacant and not in use. The PGA West golf course development to the south of the subject site had been constructed by this time. Groundwater Occurrence and Quality The Coachella Valley Water District (CVWD) supplies potable water to the City of La Quinta. Water is pumped from an underground aquifer beneath the City and treated for domestic use. The r quality of groundwater of the aquifer is good -variable at depths greater than 500 feet below the ground 4.3-5 Country Club of the Desert Final EIR November 2000 4.3 Hydrology and Water Quality surface where the potable water is withdrawn,_A well near. the project site that -pumps at --depths of --740 to 1,048 feet has produced groundwater with naturally occurring mineral levels that exceopted ------------ ..-..... --- --ed ad--- water standards. roundwater quality is poor to marginal at depths less than 200 feet below the ground surface. Other water pumped from the aquifer is used for irrigation of golf courses and agricultural land. Threats to the groundwater quality in the La Quinta area include a high nitrate concentration plume extending southeasterly from near Cathedral City toward La Quinta. Other potential threats to groundwater quality include pesticides and commercially -produced fertilizers used for agricultural production, and septic tank system effluent. Surface Water Occurrence and Quality The nearest surface water to the project is the Coachella Canal, which carries water from the Imperial Reservoir on the Colorado River, through the City, to Lake Cahuilla. The water has a higher mineral content than the local groundwater supply and is not suitable for drinking without treatment. Instead, it is used primarily for irrigation purposes, including golf course and agricultural irrigation. On -Site Water Quality Three groundwater wells are located on the site. The depth to groundwater in these wells ranges from 44.8 to 78.5 feet below ground surface. No water quality reports for these wells have been found, although the results are expected be similar to the two wells on Madison Street south of Avenue 54 (well nos. 6723 and 6724) downstream of the site which are relatively good. IMPACT ANALYSIS Impact Significance Criteria Relative to Hydrology and water quality, Appendix G of the CEQA Guidelines suggests that a project may result in a significant effect on the environment if it would: 1. Violate any water quality standards for waste discharge requirements; 5 These wells are pumped from depths of 350 to 800 feet and were sampled on December 16, 1997, for groundwater quality. 4.3-6 Country Club of the Desert Final EIR.

Emissions calculations are provided in Appendix 4.7. Totals in table may not appear to add exactly due to rounding in the computer model calculations. ' Includes trucks, material transport vehicles, and construction employee vehicles. j As shown, the emissions of PMto would exceed the thresholds of significance recommended by the SCAQMD during the site preparation phase. During the construction phases of development, emissions of VOC would exceed the recommended daily threshold. This is a result of emissions associated with the application of architectural coatings. These calculations assume that emissions would not only be generated at the time that the coatings are being applied, but also for several days following application as the coatings dry. Because these emissions exceed the SCAQMD's recommended threshold, they are considered significant. Emissions of CO, NOx and SOx would not exceed the recommended thresholds during site preparation and construction, and are not considered significant. 4.7-12 Country Club of the Desert Final EIR LNovember 2000 4.10 Utilities and Service Systems basin -wide overdraft would reach 198,000 acre feet/year by 2015. Water shortages could occur well before the year 2015. CVWD is planning to install additional ponds that would be needed for groundwater recharge in the lower valley by 2015. City of La Quinta Water System In 1992, the City of La Quinta General Plan identified a current city-wide water consumption at that time of approximately 8.93 million gallons per day. CVWD supplies water throughout La Quinta from 13 wells located throughout the city. To obtain high quality soft water for potable use, active wells are perforated at depths ranging from 500 to 900 feet, although water is normally encountered at 120 to 150 feet. Water quality analyses conducted at these sites have indicated that quality levels meet state standards. Potable water is stored in five even reservoirs that serve -the-five pressure zones in the city. This high quality water is distributed to end users via an underground system with lines ranging in size from six to 36 inches. The nearest reservoir to the proposed project site is located along Madison Street within the PGA West community. A 12 -inch water main has been installed in Jefferson Street along the western site boundary.

Water Conservation Programs Both the CVWD and the City of La Quinta encourage water conservation through the use of xeriscaping techniques to reduce water consumption through irrigation. CVWD will provide the services of a water management specialist during the landscaping/ irrigation system plan check process, to help develop an efficient, low-water volume landscaping program for new developments. The City of La Quinta has adopted a set of stringent water efficient landscaping regulations, as Chapter 8.13 of the City of La Quinta Municipal Code. The purpose of these regulations is to establish minimum water efficient landscape requirements for newly installed and rehabilitated landscapes, and to implement the minimum requirements of the State of California Water, Conservation and Landscaping Act, Statutes of 1990, Chapter 1145. The proposed project would be subject to the provisions of Chapter 8.13, pursuant to Section 8.13.030 of the Municipal Code. i 4.10-2 Country Club of the Desert Final EIR November 2000 4.10 Utilities and Service Systems water supply and demand assessment of the reliability of water service to customers during normal, dry, and critically dry runoff years. The water supply and demand assessment must compare the total water supply available to the water supplier with the total projected water use over a 20 -year period, which must be analyzed in five-year periods for each type of runoff scenarios. The management plans must also be updated every five years, to occur in years ending in 0 and 5. CVWD conducts regular water supply planning efforts to address all of these requirements, and is currently in the process of preparing a basin -wide water management plan. SB 901 directs water agencies to provide such information in response to a Notice of Preparation of an EIR (NOP) for applicable projects. peri d tk Although the local water agency, the Coachella Valley Water District (CVWD), did not respond to the NOP for this project, CVWD staff did provide information concerning their water supply planning efforts and water conservation and replenishment programs for discussion in this EIR. This section incorporates the information provided by CVWD staff. Wastewater Collection and Treatment Wastewater generated within the project vicinity is collected and treated by the CVWD. A network of sewer lines flow to an 18 -inch force main that conveys wastewater generated within the City to the Mid -Valley Water Reclamation Plant. The force main is located along the western and southern boarders of the proposed project site in Jefferson Street and a portion of Avenue 54. The Mid -Valley Water reclamation Plant serves numerous Coachella Valley communities, including La Quinta. It has a current capacity of 4.;S even million gallons per day and presently treats approximately 3.49 million gallons per day. Solid Waste Disposal Approximately 28,500 tons of solid waste are generated on an annual basis in the in the City of La Quinta. Of this total, approximately 33 percent is green waste (e.g., grass and landscape clippings), 20 percent is inert solids such as rocks and concrete, 12 percent is wood wastes, and 12 percent is paper products. The City of Las Quinta does not contain industries that produce or handle toxic or hazardous materials as a product or by-product of manufacturing processing. The City does have businesses and activities 4.10-4 Country Club of the Desert Final EIR November 2000 4.10 Utilities and Service Systems Coachella Valley and Riverside County to construct and operate a transfer station/MRF in the near future. The City of La Quinta agreed to participate in this program on February 18, 1997. IMPACT ANALYSIS Impact Significance Criteria Existing utility and service facilities are presently provided to the vicinity of the project site. Therefore, no new facilities would be needed to accommodate the project. For the purpose of this EIR, the proposed project would cause a significant impacts to utility and service systems if adequate amounts of potable and irrigation water were readily available to accommodate the project, if the capacity of the wastewater treatment plant is inadequate to accommodate the increased generation of the project, and if the project not implement measures to reduce the amount of solid waste entering landfills in accordance with State, County, and City standards. Project Impacts Water Supply and Distribution Construction Impacts During the construction phases of development, non -potable water would be used to suppress dust generated by earthmoving activities, the operation of vehicles on dirt surfaces, and exposed dirt surfaces. This water would be obtained from the Coachella Canal. According to CVWD staff, the existing non -potable water supplies are adequate to serve the proposed project without causing any significant impacts. Operational Impacts Potable water would be provided to the project by the CVWD through the exis`:--o 12 inch wmain atey tHr-aifa iii Jeffefson Sir eeta system of wells reservoirs, and eater transmission lines.

However, swater conservation measures for both landscaping and irrigation, and plumbing controls may be identified and placed as conditions on the connection of the project to the CVWD's facilities. Wastewater Collection and Treatment A wastewater collection system is proposed to be constructed within the project site with one or two connection points to the existing 18 -inch force main in Jefferson Street and Avenue 54. Sewer lift stations and force mains would be required at the collection points within the project site. The proposed project is expected to generate approximately 212,575 gallons of wastewater per day. According to CVWD staff, the existing wastewater mains and treatment plant adequate capacity to serve the proposed project without causing any significant impacts on their service levels. Solid Waste Disposal Construction Impacts Assuming that approximately 500 acres of the site would be constructed with buildings and paved surfaces, site preparation and construction activities are estimated to generate a total of approximately 45,000 tons of construction wastes over its build -out period based on an approximate generation rate of 90 tons per acre.2 These waste materials are expected to be typical construction debris, including wood, paper, glass, plastic, metals, cardboard, and green wastes. Construction activities could also generate 2 This rate was provided by Jim Harter of the Newhall Ranch Company, based on his firm's years of experience developing similar types of projects in non -desert areas in Los Angeles County. Total 'green wastes' generated during construction of this project would be less than the average of Los Angeles County projects, since the project site is comprised of desert terrain, with relatively little vegetation cover, compared to non -desert land in Los Angeles County. 4.10-9 Country Club of the Desert Final EIR November 2000
