1 IV. ENVIRONMENTAL IMPACT ANALYSIS K. WATER SUPPLY 1. INTRODUCTION This section addresses the water demand generated by the proposed project and assesses whether there is sufficient water capacity to meet the project demand. Water supply was analyzed using data provided in the Water Supply Assessment prepared by the Los Angeles Department of Water and Power (LADWP), Water Resources Business Unit, January 23, The Water Supply Assessment is provided in Appendix I of this EIR. 2. ENVIRONMENTAL SETTING a. Regulatory Framework (1) State (a) Senate Bill 610 and Senate Bill 221 State legislation addressing water supply, Senate Bill (SB) 610 (Costa) and SB 221 (Kuehl), became effective January 1, SB 610, codified in the California Water Code (CWC), Section et seq., describes requirements for both water supply assessments and Urban Water Management Plans (UWMP) applicable to the CEQA process. SB 610 requires that for specified projects subject to CEQA, the urban water supplier must prepare a water supply assessment that determines whether the projected water demand associated with a proposed project is included as part of the most recently adopted UWMP. Specifically, a water supply assessment shall identify existing water supply entitlements, water rights, or water service contracts held by the public water system, and prior years water deliveries received by the public water system. In addition, it must address water supplies over a 20-year period and consider average, dry, and multiple dry years. In accordance with SB 610 and Section of the Water Code, such projects subject to CEQA requiring submittal of a water supply assessment include the following: Residential developments of more than 500 dwelling units. Shopping center or business establishment employing more than 1,000 persons or having more than 500,000 square feet of floor space. Page 640

2 Commercial office buildings employing more than 1,000 persons or having more than 250,000 square feet of floor space. Hotels, motels, or both, having more than 500 rooms. Industrial, manufacturing, or processing plants, or industrial parks planned to house more than 1,000 persons, occupying more than 40 acres of land, or having more than 650,000 square feet of floor area. Mixed-use projects that include one or more of the projects specified in this subdivision. A project that would demand an amount of water equivalent to or greater than the amount of water required by a 500 dwelling unit project. The water supply assessment must be approved by the public water system at a regular or special meeting and must be incorporated into the CEQA document. The lead agency must then make certain findings related to water supply based on the water supply assessment. In addition, under SB 610, an urban water supplier responsible for the preparation and periodic updating of an UWMP must describe the water supply projects and programs that may be undertaken to meet the total project water use of the service area. If groundwater is identified as a source of water available to the supplier, the following additional information must be included in the UWMP: (1) a groundwater management plan; (2) a description of the groundwater basin(s) to be used and the water use adjudication rights, if any; (3) a description and analysis of groundwater use in the past five years; and (4) a discussion of the sufficiency of the groundwater that is projected to be pumped by the supplier. SB 221 also addresses water supply in the land use planning process and focuses on new residential subdivisions in non-urban areas. SB 221 requires that written verification from the water service provider be submitted indicating sufficient water supply is available to serve a proposed subdivision, or the local agency shall make a specified finding that sufficient water supplies are or will be available prior to completion of a project. SB 221 specifically applies to residential subdivisions of 500 units or more. In addition, Government Code Section (i) exempts any residential project proposed for a site that is within an urbanized area and has been previously developed for urban uses, or where the immediate contiguous properties surrounding the residential project site are, or previously have been, developed for urban uses, or housing projects that are exclusively for very low and low-income households. The project is subject to the requirements of SB 610 as the project includes 262 residential units, an additional 358,881 square feet of shopping center space, and Page 641

3 106,523 square feet of new office that together generate a demand for water that would be greater than the demand generated by 500 residential units. The project does not propose development of 500 or more dwelling units and the project site is located within an urbanized area. Therefore, the project is not subject to the requirements of SB 221. (b) California Urban Water Management Plan Act The California Urban Water Management Planning Act (CWC Division 6, Part 2.6, Sections ) addresses several state policies regarding water conservation and the development of water management plans to ensure the efficient use of available supplies. The Act also requires water suppliers to develop water management plans every five years to identify short-term and long-term demand management measures to meet growing water demands during normal, dry, and multiple-dry years. Specifically, municipal water suppliers that serve more than 3,000 customers or provide more than 3,000 acre-feet (AF) per year of water must adopt an urban water management plan (UWMP). (c) California Code of Regulations Title 20, Section (h) and (i) of the California Code of Regulations (CCR) establishes efficiency standards (i.e., maximum flow rates) for all new federally-regulated plumbing fittings and fixtures, including showerheads and lavatory faucets. Accordingly, the maximum flow rate for showerheads and lavatory faucets are 2.5 gallons per minute (gpm) at 80 pounds per square inch (psi) and 2.2 gpm at 60 psi, respectively. In addition, Section (h) establishes state efficiency standards for non-federally regulated plumbing fittings, including commercial pre-rinse spray valves. (d) Global Warming and Climate Change Global warming and climate change should be considered in assessing water supply in California. Potential impacts of climate change on California s water resources include changes in both water and air temperature, changes in precipitation patterns, and changes in sea levels that could increase pressure on Delta levees. The impact of climate change on California s water supply has already been the subject of study. California Department of Water Resources (DWR) prepared a July 2006 report entitled Progress on Incorporating Climate Change into Management of California s Water Resources, which found that climate change may have a significant effect on California's future water resources and demand. This report also examined the potential impacts of selected climate change scenarios on operations of the State Water Project and Central Valley Project, Delta water quality, flood management and evapotranspiration. Potential issues include a reduction of Sierra snow pack and seasonal water Page 642

4 storage; increased rain and less snow impacting supply reliability and hydropower generation; increased variable precipitation and extreme weather events; and rising sea levels. While climate change is expected to continue through at least the end of this century, the magnitude and nature of future changes are uncertain. This uncertainty serves to complicate the analysis of future water demand, especially where the relationship between climate change and its potential effect on water demand is not well understood (DWR report at pg. 2-54). Based on this information, the project has determined that global climate changes and their potential effects on California s water supply are too speculative at this time for further evaluation. For further discussion on the effects of global climate change, please refer to Section IV.B., Air Quality. (2) Local (a) Ordinance Nos. 172,075 and 163,532 The (the City) adopted several ordinances in an effort to reduce water consumption. Specifically, the Ordinance No. 172,075, adopted in 1998, (Chapter XII, Article II, of the LAMC) requires all building owners to install low-flow showerheads (with a maximum flow of 2.5 gpm), water closets (with a maximum flow of 3.5 gpm), and low flow urinals (with a maximum 1.5 gallons per flush) prior to obtaining building permits. City Ordinance No. 163,532 (Chapter XII, Article IV, of the LAMC) also requires a 10 percent reduction in irrigation for large turf areas (three acres of turf or greater). (b) 2005 Urban Water Management Plan In accordance with the California Urban Water Management Planning Act, the LADWP has prepared an updated Year 2005 Urban Water Management Plan (UWMP). The UWMP details the LADWP s efforts to promote the efficient use and management of its water resources. LADWP s UWMP used a service area-wide method in developing its water demand projections. This methodology does not rely on individual development demands to determine area-wide growth. Rather, the growth in water use for the entire service area was considered in developing long-term water projections for the through the year In the next UWMP update (available in 2010), the LADWP will develop a revised demand forecast that will factor in the water demand for which all water supply assessments have been prepared in addition to future demands. This will also allow LADWP to work collaboratively with its supplemental water supplier, the Metropolitan Water District of Southern California (MWD), to ensure the City s anticipated water demands are incorporated into MWD s long-term water resources development plan. Page 643

5 b. Existing Conditions (1) Water Supply LADWP is responsible for providing water within the limits and ensuring that the delivered water quality meets applicable California health standards for drinking water. As the proposed project is located within the, LADWP would be the water provider for the project. Water is supplied to the City from local groundwater, the Los Angeles Aqueducts (LAA), and the MWD. In year 2006, approximately 60 percent of LADWP s water supply was from the LAA, approximately 10 percent came from local groundwater, approximately 29 percent from the MWD, and a remaining one percent was from recycled water. 202 In addition to the local groundwater sources used throughout the City, LADWP operates the Los Angeles-Owens River Aqueduct and is a member of the MWD. (a) Los Angeles Aqueducts Water supplies from the LAA originate from both streams and groundwater and can fluctuate yearly due to varying hydrologic conditions. LAA stream supplies are primarily collected from snowmelt runoff from the Eastern Sierra Nevada Mountains, which is conveyed to the via the LAA. The City holds water rights in the Eastern Sierra Nevada where the LAA supplies originate. Secondarily, LAA supplies come from groundwater pumping. In recent years, LAA supplies have been less than normal due to environmental obligations to restore Mono Lake and mitigate dust from Owens Lake. LADWP s ability to export Mono Basin water is now tied directly to the elevation of Mono Lake and flows of various streams that are tributary to Mono Lake. As such, when Mono Lake reaches its target elevation, exports from the Mono Basin can increase from its current levels of 16,000 AF a year. (b) Groundwater LADWP extracts groundwater from various locations throughout the Owens Valley and four local groundwater basins: San Fernando, Sylmar, Central, and West Coast groundwater basins. As the LADWP owns extensive property in the Owens Valley, it appropriates groundwater for use in the Owens Valley and in Los Angeles. The groundwater basins in Los Angeles County have been adjudicated, meaning that the groundwater supplies and quantities have been assigned by the courts to existing users. The San Fernando Basin, which consists of 112,000 acres of land and comprises 91.2 percent of the Upper Los Angeles River Area (ULARA) valley fill, is the largest of the four local basins within the ULARA. LADWP has 202 Water Supply Assessment for the Project, Los Angeles Department of Water and Power, Water Resources Division, January 23, Page 644

6 accumulated nearly 320,000 AF of stored water credit in the San Fernando Basin as of October 2005, which can be withdrawn from the basin during normal and dry years or in an emergency, in addition to LADWP s approximately 87,000 AF annual entitlement in the basin. As such, the majority of LADWP s groundwater is extracted from the San Fernando Basin. Sylmar Basin, located in the northern part of the ULARA, consists of 5,600 acres and comprises 4.6 percent of the ULARA valley fill. LADWP has an annual entitlement of 3,255 AF from the Sylmar Basin. LADWP additionally has adjudicated rights to extract groundwater from the Central and West Coast Basins. Annual entitlements to the Central and West Coast Basins are 15,000 AF and 1,503 AF, respectively. Currently, LADWP does not exercise its pumping rights at the West Coast Basin due to localized water quality issues. Table 70 on page 646 shows the latest extractions by LADWP from Owens Valley, and the San Fernando, Sylmar, Central, and West Coast Basins. As shown in Table 70, from October 2005 through September 2006, LADWP extracted 57,412 AF from Owens Valley, 35,428 AF from the San Fernando Basin, 1,853 AF from the Sylmar Basin and 13,395 AF from the Central Basin. LADWP plans to continue to maximize production from its groundwater basins in the coming years to offset reductions in imported supplies. Extraction from the basins will however be limited by water quality and overdraft protection. (c) Metropolitan Water District of Southern California (MWD) The MWD is the largest water wholesaler for domestic and municipal uses in Southern California. MWD imports a portion of its water supplies from Northern California through the State Water Project s California Aqueduct and from the Colorado River through MWD s own Colorado River Aqueduct. MWD s long-term plans to meet its member agencies growing demands are through water transfer programs, outdoor conservation measures, and development of additional resources such as recycling, brackish water desalination, and seawater desalination. Additionally, MWD has more than 3.8 million AF of storage capacity available in reservoirs and banking/transfer programs, with approximately 2.5 million AF currently in that storage. As one of 26 member agencies of MWD, the LADWP purchases water to supplement LADWP supplies from the LAA and local groundwater. As of June 2005, LADWP has a preferential right to purchase percent of MWD s total water supply. In addition, LADWP intends to work within MWD s Water Surplus and Drought Management Plan to acquire its drought supplies from MWD in the future. The amount of water that MWD will be able to supply to Southern California in the near future is uncertain given the recent federal court case Natural Resources Defense Council, et al. vs. Kempthorne, et al. (NRDC). In Spring 2007, various environmental groups sought to halt the Page 645

In May 2007, a federal court invalidated the Biological Opinion issued by the U.S. Fish & Wildlife Service, which had held that the Delta smelt were in no jeopardy from operational changes of the State Water Project in the Delta. On May 31, 2007, the California Department of Water Resources (DWR) voluntarily shut down the State Water Project s pumps for 17 days in an effort to protect the Delta smelt. In an August 2007 oral decision, the federal court agreed to institute interim protective measures that restrict water operations in the Delta, including reducing the amount of water being pumped out of the Delta between the end of December and June. In December 2007, the federal court issued an interim remedial order, requiring the U.S. Fish & Wildlife Service to revise its Biological Opinion by September 15, 2008 and conditioning Delta operations on various requirements. LADWP estimates that MWD may receive 20 to 30 percent less water from the State Water Project as a result of this interim remedial order. However, this remedial order sunsets in September 2008, at which time a new Biological Opinion will govern operations of the Delta. At this time, it is not known how the future Biological Opinion will impact MWD s ability to supply water to Southern California. At present, both the California state government and MWD are evaluating Delta operations and options to address Delta smelt impacts and other environmental concerns. The Governor s Delta Vision Process and the Bay-Delta Conservation Plan are both focused on finding and implementing long-term solutions for the Delta. MWD is also actively engaged in improving Delta water operations. In May 2007, MWD s Board adopted a Delta Action Plan as a framework to address water supply risks in the Delta both for the near- and long-term. The near- and mid-term actions outlined in the Delta Action Plan are intended to implement measures to reduce fishery and earth-quake related risks, such as aggressive monitoring, ecosystem restoration, local water supply projects, and emergency preparedness and response plans. Page 646

8 In response to recent developments in the Delta, MWD is also engaged in identifying solutions that, when combined with the rest of its supply portfolio, will ensure a reliable longterm water supply for its member agencies. In the near-term, MWD will continue to rely on the plans and policies outlined in its Regional Urban Water Management Plan (RUWMP) and Integrated Water Resources Plan to address water supply shortages and interruptions (including potential shut downs of State Water Project pumps) to meet water demands. Campaigns for voluntary conservation, curtailment of replenishment water and agricultural water delivery are some of the actions outlined in the RUWMP. If necessary, reduction in municipal and industrial water use and mandatory water allocation could be implemented. (d) Water Conservation and Recycling In order to meet future water demands, water conservation and recycling will continue to play an important role. LADWP has implemented water conservation and recycling measures with efforts to further promote and increase the level of such programs. Thus, LADWP is committed to supply a higher percentage of the City s water demand through water conservation and recycling. Table 71 on page 648 presents LADWP water supplies over the last ten years from local groundwater, LAA, MWD, and recycled water resources. As shown in Table 71, LADWP had an available water supply of 634,988 AF for the year (2) Water Demand LADWP s 2005 UWMP projections in five-year increments from 2010 to 2030 are based on projected population estimates provided by the Southern California Association of Governments (SCAG). Table 72 on page 648 shows the projected water demand for the City of Los Angeles from the year 2000 through As shown in Table 72, the yearly water demand has increased linearly by approximately 17,000 AF per year (AFY). 203 The City s water demand for the year 2030 is forecasted to be approximately 776,000 AFY. Utilizing the current demand per capita provides a conservative estimate of projected future water demand to ensure that water supplies are available to meet projected demands. The LADWP anticipates adequate water supplies would be available to the service areas under normal, single-dry, and multiple-dry year conditions through The existing uses on the project site include approximately 742,815 square feet of retail and restaurant uses, 90,578 square feet of cinema uses with 3,074 seats, 298,718 square feet of office uses at 1801 Avenue of the Stars, and 62,246 square feet of office uses at 1930 Century 203 This approximate water demand increase also includes the year 2000 which was based on dry weather conditions, while the other year projections are based on normal weather conditions.

The existing water use demand for the project site is approximately 157,298 gallons per day (gpd) or 176 AFY as presented in Table 73 on page 649. (3) Water Infrastructure The water infrastructure serving the project site consists of domestic water mains located in the adjacent City streets. Currently, 12-inch water mains exist in Santa Monica Boulevard, Avenue of the Stars, and Century Park West. An 8-inch water main is located in Constellation Page 648

In addition, a new 60-inch water main has recently been constructed across the Los Angeles Country Club, located north of the project site. This water main extends into Santa Monica Boulevard and down Century Park East; however, the water main has not been connected into the existing water system in Century City. City water mains are designed to meet fire flow requirements established by the Fire Department according to land use, as set forth in the Fire Code of the Los Angeles Municipal Code, Section There are 8 fire hydrants located adjacent to the project site, which are capable of supplying fire flow of approximately 9,000 GPM. Please refer to Section IV.I.1, Public Services - Fire Protection, for additional information regarding the project s fire flow requirements as they relate to LAFD s fire suppression capabilities. 3. PROJECT IMPACTS a. Methodology Pursuant to SB 610, LADWP conducted a water supply assessment for the proposed project as requested by the Department of City Planning. The projected Page 649

11 water demand for the proposed uses was derived from the Sewer Generation Rates table, developed by the Department of Public Works, Bureau of Sanitation (2002). LADWP independently calculated the anticipated demands of the proposed project using the project information provided. The analysis considers whether sufficient water supplies would exist in addition to the existing and planned future demands on LADWP during a single-dry year, multiple dry years, and a maximum day demand. b. Significance Threshold The following factors are set forth in the City of L.A. CEQA Thresholds Guide (2006), for consideration on a case-by-case basis for evaluation of significance: The total estimated water demand for the project. Whether sufficient capacity exists in the water infrastructure that would serve the project, taking into consideration the anticipated conditions at project build-out. The amount by which the project would cause the projected growth in population, housing or employment for the Community Plan area to be exceeded in the year of project completion. The degree to which scheduled water infrastructure or project design features would reduce or offset service impacts. Based on these factors, a project would have a significant impact on water supply if the City s water supplies would not adequately serve the proposed project or water distribution capacity would be inadequate to serve the proposed use after appropriate infrastructure improvements have been installed. c. Project Design Features The project proposes to implement water conservation features that would minimize water consumption. Such water conservation features include WeatherTRACK irrigation, which regulates irrigation schedules based on landscape needs, local weather conditions, plant type, soil type, and sun exposure; waterless urinals where appropriate; use of a high-efficiency, low-water consuming cooling tower/chiller for plant operations; variable flush toilets; and no-touch fixtures (i.e. faucets, toilets, urinals). Landscaping with drought-tolerant or native plants is also expected. The use of leak detection systems is also under consideration. Page 650

12 d. Analysis of Project Impacts (1) Construction (a) Water Demand and Distribution A short-term demand for water would occur during construction associated with demolition, excavation, grading, and other construction-related activities on-site. As the project would occur in phases over a four-year period, construction activities would occur intermittently and would be temporary in nature. Thus, the demand for water supplies for construction activities such as soil watering (i.e. for fugitive dust control), demolition and construction activities, clean up, masonry, painting, and other related activities would be temporary and would require minimal water. The demand for water is not anticipated to have adverse impacts on the available water supply or the existing water distribution system. Furthermore, the water demand generated by project construction activities would be offset by the reduction in water consumption resulting from the demolition of existing uses. Overall, demolition and construction activities would require minimal water and would not be expected to have any adverse impact on available water supplies or the existing water distribution system. Therefore, impacts associated with short-term construction activities would be less than significant. (2) Operation (a) Water Demand Development of the proposed project would result in an increase in long-term water demand for operational uses, maintenance, and other activities on the project site. According to the Water Supply Assessment prepared by LADWP for the proposed project, the project water demand increase is estimated to be approximately 134 AF annually based on review of information submitted by the Planning Department. 204 Table 74 on page 652 presents the breakdown of current and proposed types of uses and their corresponding estimated water uses. LADWP s 2005 UWMP projects yearly water demand to reach 776,000 AF by 2030, or have an increase of 17 percent from According to Table 74, the anticipated increase in water usage of 134 AF annually would fall within the available and projected water supplies for normal, single-dry, and multiple-dry years through the year 2030 water demand projections of LADWP s 2005 UWMP. Therefore, LADWP concludes that it would be able to meet the water 204 This estimate of increased water demand does not take into account existing outdoor water usage at the site and therefore, is considered to be conservative.

Source: Water Supply Assessment for the Project, Los Angeles Department of Water and Power, Water Resources Division, January 23, demand of the project as well as existing and planned future water demands of its service area. As such, project impacts on water supply would be less than significant. As discussed above, the new Biological Opinion in the NRDC case, to be issued by September 2008, may impact MWD s ability to supply water to Southern California in the Page 652

14 future, however that impact cannot be determined at this time. Nonetheless, the consequences for the project s water supply should be minimal. LADWP, and thus the project, only receives approximately one-third of its water supply from MWD; the remainder of LADWP s water comes from local groundwater and the LAA. Additionally, restoring the Delta s water capacity is a high priority for MWD, the Governor and the California Legislature; extensive plans are already underway for improving the operation of the Delta s water pumps while also protecting the Delta smelt and other endangered fish species. In June 2007, MWD s Board of Directors adopted an Action Plan to implement immediate short- term actions to stabilize the Delta and mid-term and long-term actions to find an ultimate solution to the Delta s sustainability. The Governor has made the Delta and statewide water policy a high priority by establishing the Delta Vision Process and the Bay-Delta Conservation Plan, and the California Legislature is using SB 27 to find a long-term water supply solution for the Delta. As a result of these plans, MWD s water supply may be restored to previous levels in the next few years. Consequently, NRDC is not expected to impact the project s water supply. However the Applicant will continue to coordinate with LADWP to ensure adequate water supply to the project. In addition, compliance with State laws regarding water conservation measures, including pertinent provisions of Title 20 and Title 24 of the California Code of Regulations, would reduce the project water consumption estimates for the project at full build out, thereby reducing the demand on City supplies. (b) Water Infrastructure The water infrastructure serving the project site consists of domestic water mains located in the City streets surrounding the project site including 12-inch water mains in Santa Monica Boulevard, Avenue of the Stars, and Century Park West, and an 8-inch water main located in Constellation Boulevard. With regard to domestic water, these mains have adequate capacity to accommodate the water demand increase of 134 AF annually that would be generated by the proposed project. However, in order to provide adequate fire flow capacity to the project as requested by the Fire Department, water infrastructure improvements would be required. The Applicant has been coordinating with LADWP and LAFD during the development of the project plans in order to ensure that adequate water flow is provided. With implementation of Mitigation Measure I.1-1 as described in Section IV.I.1, Public Services Fire Protection, of this Draft EIR, potential impacts related to the provision of fire flow to accommodate the project would be reduced to a less than significant level. (3) Consistency with Applicable Regulations (a) Senate Bill 610 and Senate Bill 221 The proposed project meets the requirements of SB 610 which requires the urban water supplier to prepare a water supply assessment determining whether the projected water demand Page 653

15 associated with the proposed project is included as part of the most recently adopted UWMP. The proposed project is consistent with SB 610 as confirmed by LADWP, the water supplier for the, in its Water Supply Assessment for the proposed project. As indicated above, the project would not be subject to the requirements of SB 221 since the project does not include 500 residential units or more and the project site is within an urbanized area and has been previously developed for urban uses. (b) California Urban Water Management Plan Act The LADWP is consistent with this Act as the LADWP Urban Water Management Plan is updated every five years. The next update will be available in (c) California Code of Regulations The proposed project would either meet or exceed the water efficiency requirements set forth by Title 20 of the CCR through incorporation of water conservation features that would include, but not be limited to, high efficiency toilets and urinals, plumbing fixtures that reduce potential water loss from leakage due to excessive wear of washers, automatic faucet/toilet controls (sensors), and faucet flow restrictors. As such the project would be consistent with applicable regulations. (d) Ordinance Nos. 172,075 and 163,532 The proposed project would be consistent with Ordinance Nos. 172,075 and 163,532, as design features associated with the project would include facilities and fixtures with established maximum flow rate standards. As described above, the proposed project would include water conservation measures such as WeatherTRAK irrigation, variable flush toilets, and no-touch fixtures. (e) 2005 Urban Water Management Plan As discussed above, the projected water demand for the project would fall within the LADWP projected future water demands set forth in the 2005 UWMP. In addition, the UWMP indicate that water would be available to meet the water demand of the projected service area until CUMULATIVE IMPACTS As discussed above, LADWP, as a public water service provider, is required to prepare and periodically update an UWMP to plan and provide for water supplies to serve existing and Page 654

16 projected demands. The UWMP prepared by LADWP accounts for existing development within the City, as well as projected growth anticipated to occur through redevelopment of existing uses and development of new uses. Additionally, under the provisions of SB 610, LADWP is required to prepare a comprehensive water supply assessment for every new development project (as defined by Section of the Water Code) within its service area. The types of projects subject to the requirements of SB 610 tend to be larger projects (i.e., residential projects with at least 500 dwelling units, shopping centers employing more than 1,000 persons or having more than 500,000 SF of floor space, commercial office buildings employing more than 1,000 persons or having more than 250,000 SF of floor space, etc.) that may or may not have been included within the growth projections of the UWMP. The water supply assessment for such projects, in conformance with the UWMP, evaluates the quality and reliability of existing and projected water supplies, as well as alternative sources of water supply and measures to secure alternative sources if needed. In addition, as described above, SB 221 requires that for residential subdivisions with 500 units or more that are in non-urban areas, written verification from the service provider (e.g., DWP) be submitted indicating sufficient water supply is available to serve the proposed subdivision, or the local agency shall make a specified finding that sufficient water supplies are or will be available prior to completion of the project. Section III.B, Identification of Related Projects, of this EIR identifies related projects anticipated to be developed within the project vicinity. The water demand of the related projects is shown in Table 75 on page 656. As shown in Table 75, the related projects would have an average daily water demand of approximately 1,841,795 gpd or 2,063 AFY. The project in conjunction with the related projects would yield a total average water demand of approximately 1,961,348 gpd or 2,197 AFY. As previously stated above, the LADWP s 2005 UWMP projects yearly water demand would reach 776,000 AF by 2030 or have an increase of 17 percent from With the anticipated water demand increase of 2,197 AF annually from the development of the proposed project and related projects, the demand for water would fall within the available and projected water demand of LADWP s 2005 UWMP. In addition, given that the UWMP plans and provides for water supplies to serve existing and projected needs, including those of future growth and development as may occur through related projects, and that the requirements of SB 610 and SB 221 provide means to ensure that the water supply needs of notable development projects are carefully considered relative to LADWP s ability to adequately meet future needs, it is anticipated that LADWP would be able to supply the demands of the proposed project and related projects through the foreseeable future. In sum, LADWP would have adequate amounts of water to meet the projects future water demands for the service area with the addition of the proposed project and related projects, and no significant cumulative impacts related to water demand would occur.

Sewer Generation Rates provided by the Los Angeles Department of Water and Power, and are expressed in gallons per day (gpd) per unit (i.e., per room, per du, per bed, per 1,000 sq ft, or per student). The project water demand is anticipated to be approximately 125 percent of the wastewater generation for a conservative estimate. 1 acre foot = 325,851 gallons. The water demand was obtained from the 2002 Long Range Development Plan Final Environmental Impact Report prepared for the University of California, Los Angeles. Unable to calculate because there is no designated generation flow rate for a mausoleum building. As these school expansions and developments are presented by square footage, Church School: One Day Use generation flow rate was used for these uses because it is expressed in gpd per1,000 square foot. Calculated by beds with the assumption of two beds per dwelling unit. Source: PCR Services Corporation, MITIGATION MEASURES The proposed project would not result in significant environmental impacts relating to domestic water supply, and therefore, mitigation measures are not required. Please refer to Section IV.I.1, Public Services Fire Protection, for mitigation regarding fire flow. 6. LEVEL OF SIGNIFICANCE AFTER MITIGATION No significant impacts to the City s water supply would occur as a result of the proposed project. Page 660
