A residential parking permit district (Parking District 11) has been established for the area bounded by Buckingham Parkway and the City boundary as well as the area between Green Valley Circle and the Hillside Memorial Park, but no restrictions have been imposed. The Project is not within the limits of Parking District 11.
Regular use of the on-s treet parking on Buckingham Parkway and Green Valley Circle by future residents or visitors to the Project is unlikely, given the time-consuming and circuitous pedestrian route required to reach the Project from these locations. Because the neighboring area has already established a residential parking permit district, they have the ability to enact regulations to protect on-street parking within the district from long-term use by future residents of the Project.

From: Kimley-Horn and Associates, Inc.
Michael Choi, P.E., LEED AP
C
C: Mr. Andy Beck
Subject: 5757 Uplander Way – Wastewater Civil Technical Memorandum
Introduction
The Project site is comprised of approximately 8.3 acres and existing improvements include 4 s
eparate, 2-story buildings totaling to be 103,027 sf. Existing improvements also comprise of landscaping along the front of the site, as well hardscaping adjacent to the existing buildings for the purpose of parking. The proposed development proposes to construct 6 new, 5-story buildings with 2 levels of subterranean parking, totaling in at 7-stories.
Kimley-Horn and Associates, Inc. is providing this wastewater civil technical memorandum based on our review of the PPR2 Draft Concept Plan received August 18, 2024, prepared by KFA and our understanding of the existing utilities surrounding the site. A summary of our wastewater utility analysis for the proposed development is provided below.
Existing Improvements
Existing sewer lines within Culver City are maintained by the City of Culver City’s Public Works D
epartment. The existing sewer system adjacent to the project site is based on available record documents obtained from the City’s online Sewer Infrastructure Management System (SIMS) and is described further below:

• Bristol Parkway: Along Bristol Parkway, there is an existing 8” vitrified clay pipe (VCP) sewer line.
The 8” pipe begins at the northeast corner of Hannum Ave and Bristol Pkwy at manhole G6-31 and flows in the south/southwest direction. The sewer line is later joined at the Bristol Pkwy and Sumner intersection by two, existing 8” VCP sewer lines at sewer manhole G6-28. The sewer line becomes a 10” VCP downstream of manhole G6-28.
• Uplander Way/Sumner Way per ALTA/NSPS Survey: Along Uplander/Sumner Way, there is an existing 8” vitrified clay pipe, sewer line. The 8” pipe connects to the sewer line at the intersection of Bristol Pkwy and Uplander/Sumner Way along the west side and later terminates at manhole G6-30, adjacent to of Lot 12 of the Project site on the east side of the pipe.
• North Outfall Replacement Sewer: Starting at Bristol Parkway, there is an existing 150” reinforced concrete pipe that goes through Lot 8 of our Project site. The 150” RCP flows in the southerly direction and is owned by the City of Los Angeles.
Proposed Improvements
The following are
based on PPR2 Draft Concept Plan received July 25, 2024, prepared by KFA:
Proposed Project Development Programming: The project will develop or include the following:
• Residential – 837,855 (1,077 units)
o Studio – 145 units
o 1 Bedroom – 644 units
o 2 Bedrooms – 288 units
• Retail – 5,772 SF
• Fitness Center – 6,070 SF
Other development programming such as lobby, general residential amenity areas, community pool and subterranean parking areas were not accounted for since the County of Los Angeles Sewer Generation rates do not include these categories.
Proposed Sewer Demand:
Based on the above summary, the proposed project will generate 0.264 cfs (170,410 GPD) or 0.659 cfs (426,026 GPD) peak flow (including the peak factor of 2.5) of additional sewer discharge to the existing sewer system around the project site. Our detailed analysis based on the LA County wastewater generation factors is summarized in the tabulation provided below.

Sewer Flow Monitoring Study Results
The Project proposes to connect two proposed sewer laterals at the south and west sides of the p
roject site from the proposed development to the 8” sewer main between manholes G6-31 and G6- 70, as well as, between manholes G6-30 and G6-29. Utility Systems Science & Software conducted a sewer metering and flow monitoring study of existing manhole G6-71, G6-29 and G6-27 to assess the existing sanitary sewer system’s capacity within Bristol Parkway and Uplander/Sumner Way adjacent to the site. Sewer metering was conducted using a FloDar AV Sensor, over a 2-week period between the dates of March 9, 2024, and March 25, 2024. See Appendix 1 for the US 3 sewer monitoring r
esults.
- Manhole #G6-71 (Bristol North): Based on the April 2, 2024, data reports from US 3, manhole #
G6-71 has a maximum flow rate of 0.009 million gallons per day (0.017 cfs).
- Manhole #G6-29 (Uplander): Based on the April 2, 2024, data reports from US 3, manhole #G6-29 Kimley>>>Horn
kimley-horn.com 660 South Figueroa Street, Suite 2050, Los Angeles, CA 90017 213 261 4040
has a maximum flow rate of 0.012 million gallons per day (0.022 cfs).
- Manhole #G6-27 (Bristol South): Based on the April 2, 2024, data reports from US 3, manhole #
G6-27 has a maximum flow rate of 0.064 million gallons per day (0.12 cfs).
Based on City sewer requirements, it was concluded sufficient capacity for the proposed development exists in the monitored sewer lines, since the depth of the peak flows observed during this study did not exceed d/D limits of 0.50 or 50% pipe capacity.
Based the metering results and proposed net increase, it appears there is sufficient hydraulic capacity. Since the sewer discharge split between the Bristol Parkway and Uplander Way, we’ve assessed the total project demand to either street. Our assessment adds the total development sewer discharge or demand to each manhole where the existing sewer metering was conducted. The maximum sewer flow rate from the metering was used to assess the pipe capacity at each of these locations. Based on this approach to our analysis, the site's sewer discharge could be sent to either sewer line (or split between both), and any of these scenarios would have adequate capacity to handle the additional sewer demand for the project. For example, if 100% of the sewer discharge is sent to Bristol Parkway, it would still be sufficient, as well as if 100% was sent to Uplander Way, there would still be sufficient capacity.

A Will Serve Letter from Culver City Public Works received on May 22, 2023, confirms that the pipe can be served by existing Culver City wastewater services. This letter can be found in Appendix 2.
Conclusion
Per the sewer metering performed by Utility Systems Science & Software and the Will Serve Letter fr
om Culver City Public Works, the sanitary sewer on the project can be conveyed from the project property to the existing municipal system.

1 INTRODUCTION
Included herein is a Senate Bill (SB) 610-compliant water supply assessment (WSA) in support of the 5757 Uplander Way Project ( “Proposed Project”; Figure 1 ). The Proposed Project site is comprised of approximately 8.3 acres located in the City of Culver City, California. The Proposed Project includes the demolition of the existing office/flex structures on the project site and the construction of three new, seven-story buildings totaling 1,638,819 square feet (sq ft), including 1,077 new dwelling units , 8,970 sq ft of lobby space, 6,070 sq ft of fitness center space, and approximately 5,772 sq ft of food service use on the ground floor (Link Logistics, 2024a; 2024e).
Additionally, the Proposed Project would include 532,661 sq ft of covered parking and 48,647 sq ft of irrigated landscaping (KFA Architecture, 2024; Link Logistics, 2024a). The Proposed Project is located within the Golden State Water Company (GSWC) Culver City service area, and GSWC will be the water service provider for the Proposed Project (Figure 2).
The information provided in this WSA is consistent with California Water Code ( CWC) §10910-10912 requirements and the California Department of Water Resources’ (DWR’s) Guidebook for Implementation of Senate Bill 610 and Senate Bill 221 of 2001: To Assist Water Suppliers, Cities, and Counties in Integrating Water and Land Use Planning, dated 8 October 2003.
The text of specific sub-sections of the CWC is included within gray text boxes with italicized font at the beginning of specific sections of this WSA. The information presented in those respective sections, and the associated tables and figures, respond directly to CWC requirements.
The purpose of this WSA is to evaluate whether GSWC has sufficient water supply to meet the current and planned water demands within the GSWC Culver City service area, including the demands associated with the Proposed Project, during normal, single, and multiple dry hydrologic years over a 20-year time horizon.1 More specifically, this WSA includes:
• A summary of the WSA requirements articulated in CWC §10910-10912 and a description of how they apply to the Proposed Project;
• A description and analysis of the current and projected future water demands of the Proposed Project through the year 2045;
• A description and analysis of the historical, current, and projected future water demands for the GSWC Culver City service area through the year 2045; • A description and analysis of the current and projected future water supplies for the GSWC Culver City service area through the year 2045; and • A comparison of the water supplies and demands for the GSWC Culver City service area, including the projected water demands associated with the Proposed Project. 1 The CWC specifies that a WSA must look at supplies and demand on a 20-year horizon (i.e., to 2044), but given the available data, this WSA looks beyond that to 2045.
December 2024
EKI C40017.00
Th
e information contained in this WSA is based primarily on the 2020 Urban Water Management Plan (UWMP) prepared for the GSWC Culver City service area, except where updated with relevant water demand and supply reliability and other information from sources including GSWC, the Santa Monica Basin Groundwater Sustainability Plan (GSP), and others, as noted.
This WSA concludes that sufficient water supply is available to GSWC to meet all future demands within the GSWC Culver City service area , including those associated with the Proposed Project.

2 GENERAL REQUIREMENTS FOR THE PREPARATION OF A WATER SUPPLY
ASSESSMENT
The purpose of this section is to outline what types of projects require the preparation of a WSA, who is responsible for its preparation, and the necessary components of a WSA.
2.1 Applicability of SB Bill 610 to the Proposed Project
The Proposed Project would include a residential development of m ore than 500 dwelling units and therefore satisfies the definition of a “project” requiring a WSA pursuant to SB 610 (CWC §10910(a) and 10912(a)(3)). It should be noted that per SB 221, over 500 dwelling units may also trigger the need for a Water Supply Verification.
CWC § 10910 (a)
Any city or county that determines that a project, as defined in Section 10912, is subject to the California Environmental Quality Act (Division 13 (commencing with Section 21000) of the Public Resources Code) under Section 21080 of the Public Resources Code shall comply with this part. CWC § 10912
For the purposes of this part, the following terms have the following meanings:
(a) "Project" means any of the following:
(1) A proposed residential development of more than 500 dwelling units. (2) A proposed shopping center or business establishment employing more than 1,000 persons or having more than 500,000 square feet of floor space.
(3) A proposed commercial office building employing more than 1,000 persons or having more than 250,000 square feet of floor space.
(4) A proposed hotel or motel, or both, having more than 500 rooms. (5) A proposed industrial, manufacturing, or processing plant, or industrial park 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. (6) A mixed-use project that includes one or more of the projects specified in this subdivision. (7) 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.
(b) If a public water system has fewer than 5,000 service connections, then “project” means any proposed residential, business, commercial, hotel or motel, or industrial development that would account for an increase of 10 percent or more in the number of the public water system’s existing service connections, or a mixed- use project that would demand an amount of water equivalent to, or greater than, the amount of water required by residential development that would represent an increase of 10 percent or more in the number of the public water system’s existing service connections.

EKI C40017.00
2.2 Re
sponsibility for Preparation of the Water Supply Assessment
The Proposed Project is located within the GSWC Culver City service area, and potable water for the Proposed Project will be supplied by GSWC. Therefore, in accordance with CWC §10910(b), GSWC is the entity responsible for adopting the WSA for the Proposed Project.
2.3 Components of a Water Supply Assessment
As listed above in CWC §10910(c)(4), the primary purpose of a WSA is to evaluate whether sufficient water supply is available to meet all future demands within the water supplier’s service area, including those associated with the Proposed Project, during normal and dry hydrologic years for a 20-year time horizon.
2 Therefore, the following information is included in this WSA:
2 The CWC specifies that a WSA must look at supplies and demand on a 20-year horizon (i.e., to 2044), but given the available data, this WSA looks beyond that to 2045.
CWC § 10910 (b)
The city or county, at the time that it determines whether an environmental impact report, a negative declaration, or a mitigated negative declaration is required for any project subject to the California Environmental Quality Act pursuant to Section 21080.1 of the Public Resources Code, shall identify any water system that is, or may become as a result of supplying water to the project identified pursuant to this subdivision, a public water system, as defined in Section 10912, that may supply water for the project. If the city or county is not able to identify any public water system that may supply water for the project, the city or county shall prepare the water assessment required by this part after consulting with any entity serving domestic water supplies whose service area includes the project site, the local agency formation commission, and any public water system adjacent to the project site.
CWC § 10910 (c) (4)
If the city or county is required to comply with this part pursuant to subdivision (b), the water supply assessment for the project shall include a discussion with regard to whether the total projected water supplies, determined to be available by the city or county for the project during normal, single dry, and multiple dry water years during a 20-year projection, will meet the projected water demand associated with the proposed project, in addition to existing and planned future uses, including agricultural and manufacturing uses.

4 PROJECT WATER DEMAND
The City of Culver City has adopted green building standards and water efficient landscaping ordinances consistent with previous versions of the CalGreen building standards and the California Model Water Efficient Landscape Ordinance (MWELO). Landscaping will also be consistent with Assembly Bill (AB) 1572. As part of S tate requirements, all new developments must comply with these efficiency standards. As such, the Proposed Project development is expected to include a number of water-efficient features, including, but not limited to:
• Use of low-flow lavatory faucets, kitchen faucets, toilets, and urinals in accordance with CalGreen Code; and
• Inclusion of low-water use landscaping and high-efficiency irrigation systems to minimize outdoor water use in accordance with MWELO and AB 1572.
As described below, the average annual water demand for the Proposed Project was estimated based on: (1) literature values for commercial water use (City of Los Angeles Bureau of Engineering, 2012; Los Angeles County Sanitation Districts, 2024) and (2) information about the Proposed Project provided by Link Logistics (KFA Architecture, 2024; Link Logistics, 2024a; 2024d; 2024e).
Table 1 includes a summary of the water demand projections associated with the proposed land uses at the Proposed Project completion. The Proposed Project will be implemented in a phased approach, with developments coming online by 2029, 2030, and 2031 . Full buildout of the Proposed Project is assumed to be completed by 2031 (Link Logistics, 2024b).
4.1 Indoor Water Use
Table 1 provides a summary of the land uses, unit demand factors, and respective water demands associated with each land use anticipated in the Proposed Project. Below is a summary of the calculations and assumptions for each indoor land use category.
4.1.1 Residential Use
Based on current development plans, the Proposed Project is expected to include 1,077 units of residential use (Link Logistics, 2024a). Of these 1,077 units, 558 are one -bedroom apartments, 288 are two -bedroom apartments, 145 are studio apartments, 66 are junior one -bedroom apartments, and 20 are one-bedroom town homes (Link Logistics, 2024a). The water demand for the residential use is estimated using the Los Angeles County Sanitation Districts (LACSD) wastewater generation factor for residential land uses with five or more units (LACSD, 2024). For the purpose of this analysis, wastewater flows are assumed to be 90% of the total water demand for each land use consistent with the methodology used in the Paramount Pictures Master Plan, which was approved by the City of Los Angeles in April 2016 (City of Los Angeles Department of City Planning, 2016; Incledon, 2015). As such, the LACSD wastewater generation factor for December 2024
EKI C40017.00
re
sidential land uses with five or more units was divided by 0.9 to determine a water demand factor of 173 gallons per day (gpd) per dwelling unit. Based on this residential demand factor, the total residential use for the Proposed Project at full buildout is estimated to be 209 acre-feet per year (AFY).
4.1.2 Food Service Use
The Proposed Project includes one ground- floor restaurant, totaling 5,772 sq ft of food service use (Link Logistics, 2024a; 2024d). The water demand for the Proposed Project’s food service use is estimated using the LACSD wastewater generation factor for restaurants (LACSD, 2024). Similar to the residential demand factor calculation, wastewater flows are assumed to be 90% of the total water demand for each land use. As such, the LACSD wastewater generation factor for restaurant land uses was divided by 0.9 to determine a water demand factor of 1.1 gpd per sq ft.
The resultant water demand associated with the food service portion of the Proposed Project at full buildout is estimated to be 7.2 AFY.
4.1.3 Lobby Use
The Proposed Project includes approximately 8,284 sq ft of lobby use (Link Logistics, 2024a). The water demand for the lobby use is estimated using the LACSD wastewater generation factor for professional buildings (LACSD, 2024). Similar to the residential demand factor calculation, wastewater flows are assumed to be 90% of the total water demand for each land use. As such, the LACSD wastewater generation factor for professional building uses was divided by 0.9 to determine a water demand factor of 0.33 gpd per sq ft. The r esultant water demand associated with the lobby portion of the Proposed Project at full buildout is estimated to be 3.3 AFY.
4.1.4 Fitness Center Use
The Proposed Project includes approximately 6, 070 sq ft of fitness center use (Link Logistics, 2024a). The water demand for the fitness center use is estimated using the LACSD wastewater generation factor for health spas and gymnasiums without showers (LACSD, 2024). Similar to the residential demand factor calculation, wastewater flows are assumed to be 90% of the total water demand for each land use. As such, the LACSD wastewater generation factor for health spas and gymnasiums without showers was divided by 0.9 to determine a water demand factor of 0.33 gpd per sq ft. The r esultant water demand associated with the fitness center portion of the Proposed Project at full buildout is estimated to be 2.3 AFY.
4.1.5 Other Amenity Space Use
The Proposed Project includes approximately 25,325 sq ft of other amenity use (Link Logistics, 2024a). The water demand for the other amenity use is estimated using the LACSD wastewater generation factor for professional buildings (LACSD, 2024). Similar to the residential demand factor calculation, wastewater flows are assumed to be 90% of the total water demand for each land use. As such, the LACSD wastewater generation factor for professional buildings was divided by 0.9 to determine a water demand factor of 0.33 gpd per sq ft. The resultant water demand December 2024
EKI C40017.00
as
sociated with the other amenity portions of the Proposed Project at full buildout is estimated to be 9.5 AFY.
4.1.6 Total Indoor Water Use
Based on the above calculations and assumptions, total indoor water use for the Proposed Project is estimated to be 90 AFY at full buildout.
4.2 Covered Parking Water Use
The Proposed Project includes ground floor parking, as well as two levels of subterranean parking, totaling approximately 532,661 sq ft of covered parking facilities ( Link Logistics, 2024a). Water use associated with this space is anticipated to be minimal, limited to cleaning of the facility approximately twelve times per year ( LADWP, 2022). It is assumed that 0.02 0 gallons per sq ft will be used per each cleaning event (City of Los Angeles Bureau of Engineering, 2012). Thus, it is estimated that 0.39 AFY will be used for the purpose of cleaning the parking facility.
4.3 Community Landscaping and Water Feature Water Use
The Proposed Project includes general landscaping along with three pools as a part of the residential community (collectively referred to as “water features”). The projected water demands for the community landscaping and water features were estimated based on the Maximum Applied Water Allowance (MAWA) per the MWELO (DWR, 2015). The MWELO requires that the annual estimated total water use for landscape irrigation and water features does not exceed the MAWA (DWR, 2015). As shown below, the MAWA is calculated based on the regional reference evapotranspiration rate, an evaporation adjustment factor, the total landscaped area, and the area of “special landscaped area.”
3 Water use for the Proposed Project landscaping
irrigation has been conservatively assumed to be equal to the MAWA, which is the upper limit of annual applied water for established landscaped areas and water features.
The MAWA is calculated using the following equation:
MAWA = ETo × [(ETAF x LA) + (1-ETAF) × SLA]
where:
ETo = The regional reference evapotranspiration rate
ETAF = Evapotranspiration Adjustment Factor
For residential landscaping = 0.55
For water features = 1
LA = Total landscape area (including SLA)
SLA = Special Landscape Area
3 Special Landscaped Area includes landscaping dedicated solely to edible plants, recreational areas, areas irrigated with recycled water, or water features using recycled water.
December 2024
EKI C40017.00
Ba
sed on the above methodology, and shown in Table 2, the total annual water demands for the Proposed Project’s landscaping and water features are estimated to be 2.3 AFY and 0.15 AFY, respectively, at full buildout (excluding the distribution system losses discussed in Section 4.5).
AB 1572 was signed into law in October 2023 and took effect in January 2024. This regulation prohibits the use of potable water for the irrigation of nonfunctional turf4 located on commercial, industrial, and institutional (CII) properties, other than a cemetery, and on properties of homeowners’ associations, common interest developments, 5 and community service organizations or similar entities . AB 1572, however, does not prohibit the use of potable water for irrigation of other types of landscaping, such drought-tolerant landscaping. It is important to note that MAWA already incorporates conservative measures that limit the total water use for landscape irrigation. Therefore, this WSA assumes that landscaping for the Proposed Project will be equal to the MAWA and comply with AB 1572.
4.4 Distribution System Losses
Water distribution systems experience a degree of water loss over the course of transmission from the source to the customer. Although distribution system losses from the newly constructed portion of the system’s infrastructure associated with the Proposed Project would initially be expected to be minimal, it is conservatively assumed that distribution system losses associated with delivering water for the Proposed Project will ultimately be consistent with the proportion of real and apparent water loss per the most recent (2021) validated water loss audit submitted to DWR for the GSWC Culver City service area (i.e., 4.8%; DWR, 2021). It should be noted that while these real losses represent a demand on the system, water lost through the distribution system returns to the underlying groundwater basin and thus is not a true demand on the groundwater supply. However, for purposes of this WSA, all water loss is conservatively considered a demand. Table 1 shows the distribution system losses for the Proposed Project, estimated at a total of 12 AFY at full buildout.
4.5 Existing Current Water Demand on the Proposed Project Site The Proposed Project site is currently developed with four existing business park buildings and associated surface parking (Link Logistics, 2024c). From 2022 to 2023, water use at the Proposed Project site averaged 9.4 AFY, with a maximum annual use over this period of 9.7 AFY ( Link 4 Nonfunctional turf is defined as any turf that is not functional turf, and includes turf located within street rights-of- way and parking lots. Nonfunctional turf excludes recreational areas, or area s designated by a property owner or a governmental agency to accommodate human foot traffic for recreation, including, but not limited to, sports fields, golf courses, playgrounds, picnic grounds, or pet exercise areas. 5 A common interest development is defined as a community apartment project, a condominium project, a planned development, or a stock cooperative.
December 2024
EKI C40017.00
Lo
gistics, 2024d).6 Water demand for the new development associated with the Proposed Project is conservatively assumed incremental to this existing demand, and thus, as shown in Table 1, the average existing site demand of 9.4 AFY is subtracted from the estimated demands associated with the Proposed Project.
4.6 Total Proposed Project Water Demand
Based on the above methodologies and assumptions, the total annual water demand associated with the Proposed Project at full buildout and occupancy is conservatively estimated to be 237 AFY, as shown in Table 1. Demands are assumed will come online consistent with the phased development schedule for the Proposed Project. Full buildout of the Proposed Project is assumed to be completed by 2031.
6 At the time of preparing this WSA, historical water usage data was unavailable for the first seven to eight months of 2022 for portions of the project site. For purposes of this analysis, the monthly average water use data from 2023 was used to approximate the water use for those months in 2022 in order to estimate the total annual water use at the site in 2022.

5 GSWC CULVER CITY SERVICE AREA WATER DEMAND
Consistent with the UWMP Act ( CWC §10610-10656), the 2020 UWMP presents estimates of projected future water demand for the GSWC Culver City service area in five-year increments, between the years 2025 and 2045 (GSWC, 2021). Projected water demand is subdivided between the following seven customer sectors or use types: (1) single family, (2) multi-family, (3) commercial/institutional, (4) industrial, (5) landscape, (6) other, and (7) water loss. As discussed further below, the 2020 UWMP demand projections account for: (1) demands for the existing service area and accounts, (2) projected growth based on historical growth in accounts , and (3) all anticipated new development based on information then available to GSWC.
5.1 Current and Historical Water Demand Within the GSWC Culver City Service Area Historical water demand within the GSWC Culver City service area from 2016 through 2022 is shown in Table 3 . Based on 2020 water use, the single -family residential and commercial/institutional sectors use the most water, at 34% and 33%, respectively, followed by multi-family residential at 23%. Industrial and “other” uses represent just 2.4% and 2.9% of water use, and distribution s ystem losses represent 5.3% of the service area’s water demand (GSWC, 2021). Between 2016 and 2022, water demand s remained fairly stable, averaging 4,819 AFY (DWR, 2024; GSWC, 2021).
5.2 GSWC Culver City Service Area Demand Projections
The 2020 UWMP water demand projections account for growth within the GSWC Culver City service area through 2045. The 2020 UWMP includes population growth estimates based on Southern California Association of Governments (SCAG) projections. Based on a review of historical growth in accounts and the SCAG projected population and employment, GSWC CWC § 10910 (c)
(1) The city or county, at the time it makes the determination required under Section 21080.1 of the Public Resources Code, shall request each public water system identified pursuant to subdivision (b) to determine whether the projected water demand associated with a proposed project was included as part of the most recently adopted urban water management plan adopted pursuant to Part 2.6 (commencing with Section 10610). (2) If the projected water demand associated with the proposed project was accounted for in the most recently adopted urban water management plan, the public water system may incorporate the requested information from the urban water management plan in preparing the elements of the assessment required to comply with subdivisions (d), (e), (f), and (g).
(3) If the projected water demand associated with the proposed project was not accounted for in the most recently adopted urban water management plan, or the public water system has no urban water management plan, the water supply assessment for the project shall include a discussion with regard to whether the public water system's total projected water supplies available during normal, single dry, and multiple dry water years during a 20 -year projection will meet the projected water demand associated with the proposed project, in addition to the public water system's existing and planned future uses, including agricultural and manufacturing uses.

EKI C40017.00
pro
jected the growth in accounts by sector within the Culver City service area and applied unit demand factors for each customer category to estimate future demands.
As shown in Appendix A, based on a review of the GSWC Culver City service area growth projections, GSWC has confirmed that the water demands associated with the Proposed Project’s commercial uses, landscape uses, and the corresponding water distribution losses are within the anticipated growth for the GSWC Culver City service are a. Thus, this WSA can assume that the demands for these project elements (approximately 27 AFY) were included in the 2020 UWMP for the GSWC Culver City service area, consistent with CWC §10910(c)(1) (GSWC, 2024).
However, per Appendix A, GSWC has confirmed the water demand s associated with the Proposed Project’s multi-family residential use and the corresponding water distribution losses are not included in the growth anticipated within the GSWC Culver City service area. Thus, this WSA assumes that the demands for these project elements ( approximately 210 AFY after subtracting the average existing site demand of 9.4 AFY ) are additive to 2020 UWMP demands (GSWC, 2024).
The demand projections for the GSWC Culver City service area, including the additive demands of the Proposed Project and those of other known developments , are presented in Table 4 by water use sector in five -year increments through 2045 . It is estimated that, inclusive of the Proposed Project, the total annual water demand for the GSWC Culver City service area will be approximately 5,680 AFY in 2045.
5.3 Planned Development Projects Within the GSWC Culver City Service Area As discussed above, the 2020 UWMP demand projections include projections of growth within the existing service area based on historical account growth and SCAG population and employment forecasts, which included the demand associated with the Crossings Campus Building 1 Project (Crossings Project), a planned development for which a WSA was completed in 2022. The Crossings Project includes a 167,000 sq ft four -story office building with associated landscaping and covered parking. The demands associated with the Crossings Project are estimated to be 24 AFY by full buildout in 2025. The Crossings Project is considered to be included within GSWC Culver City service area’s growth projections and the 2020 UWMP demand projections (EKI, 2022).
Additionally, the 10950 Washington Boulevard mixed -use residential development is a known project within the GSWC Culer City service area for which a WSA was recently developed and finalized by GSWC in August 2024. The 5.5 acre-site would include the construction of 508 multi- family units and approximately 14,087 sq ft of commercial use (EKI, 2024). The WSA determined that the demands associated with the commercial uses, approximately 4.0 AFY by full buildout, are included in the 2020 UWMP demand projections. However, the WSA determined that the estimated demands associated with the multi-family residential uses are not included in the 2020 UWMP demand projections for GSWC Culver City ( 100 AFY). Therefore, the projected multi- December 2024
EKI C40017.00
family
residential demands that are considered additive to GSWC Culver City’s projected demands are shown in Table 4.
This WSA understands that GSWC tracks future planned water uses through service applications that it receives for new developments and has determined that all currently planned water uses, except for the multi-family residential demands and corresponding water losses associated with the 10950 Washington Boulevard development and th e Proposed Project, are accounted for in its 2020 UWMP.

Distribution losses associated with the Proposed Project's multi-family residential demands are proportional to the Proposed Project's total distribution system losses in Table 1.
Commercial and landscape demands for the Proposed Project, as well as the corresponding water losses, are within the growth anticipated by GSWC and therefore, are included in the GSWC Culver City Service Area 2020 UWMP. However, the Proposed Project's multi-family residential demands and the corresponding water losses were not included within the projected growth in the 2020 UWMP. Therefore, these demands are additive to those in the 2020 UWMP, as confirmed through correspondence with GSWC per Reference 3.
The projected water demands by sector for the GSWC Culver City Service Area are provided in the 2020 UWMP per Reference 1.

6 GSWC CULVER CITY SERVICE AREA WATER SUPPLY
This section identifies the water supplies for the GSWC Culver City service area and discusses the variability of the different supplies based on drought and other factors affecting water supply reliability. The Proposed Project will be served with potable water by GSWC , wh ich primarily relies on imported water purchased from the West Basin Municipal Water District (WBMWD) , although GSWC has previously extracted a minimal amount of groundwater from the Santa Monica Subbasin (GSWC, 2021).
6.1 Identification of Water Supply Rights
Pursuant to CWC §10910(d)(1), a WSA is required to include identification of all water supply entitlements, water rights, and water service contracts relevant to the identified water supply for the Proposed Project. In accordance with these requirements, this WSA includes a summary of GSWC’s water supply sources for the GSWC Culver City service area.
6.2 Purchased Water
GSWC purchases water for the GSWC Culver City service area from WBMWD. The water purchased from WBMWD may be managed and moved between the GSWC Culver City service area and GSWC Southwest service area, depending upon the circumstances for supply availability in each particular service area (GSWC, 2021).
GSWC entered into a five-year purchase order agreement between GSWC and WBMWD, effective 1 January 2008 through 31 December 2012. The agreement was extended an additional two years to 31 December 2014. This agreement provided GSWC with an annual maximum allocation of 30,651 AFY with a total purchase commitment of 91,953 acre-feet (AF) over the five- year term of the agreement, shared by all of GSWC’s systems served by WBMWD. At this time, this agreement has not been extended (WBMWD, 2024).
WBMWD is a member agency of the Metropolitan Water District of Southern California ( MWD).
WBMWD acts as secondary wholesale water agency, purchasing water from MWD and reselling it to GSWC. WBMWD entered into a new ten- year term purchased order with MWD effective 1 January 2015 through 31 December 2024 (WBMWD, 2021) . At this time, no new purchase order agreement has been made between WBMWD and MWD effective past 31 December 2024, per email correspondence with WBMWD (WBMWD, 2024).
CWC § 10910 (d)(1)
The assessment required by this section shall include an identification of any existing water supply entitlements, water rights, or water service contracts relevant to the identified water supply for the proposed project, and a description of the quantities of water received in prior years by the public water system, or the city or county if either is required to comply with this part pursuant to subdivision (b), under the existing water supply entitlements, water rights, or water service contracts.

EKI C40017.00
MWD s
upplies imported water sourced from the State Water Project (SWP) and the Colorado River via a series of pipelines and aqueducts. The Colorado River was MWD’s original source of water following its establishment in 1928. MWD has a legal entitlement to receive water from the Colorado River under a permanent service contract with the United States Secretary of the Interior. The Colorado River Aqueduct, which has a capacity of 1.25 million AFY , is owned and operated by MWD. It transports water from Lake Havasu, at the border of California and Arizona, approximately 242 miles west to its terminus at Lake Mathews in Riverside County and MWD’s service area (WBMWD, 2021).
MWD also imports water from the SWP, which is owned by the State of California and operated by DWR. The SWP transports Feather River water stored in and released from Oroville Dam and conveyed through the San Francisco Bay and Sacramento-San Joaquin River Delta (Bay-Delta), as well as unregulated flows diverted directly from the Bay-Delta, south via the California Aqueduct to four delivery points: one from the California Aqueduct’s West Branch at Castaic Lake and three from the East Branch along the northea stern portion of MWD’s service area between Devil’s Canyon Power Plant and Lake Perris (WBMWD, 2021).
MWD continuously engages in planning for various aspects of its water management, including operations, long-term reliability, and emergency response. These planning efforts include: (1) the 1996 Integrated Water Resources Plan (IRP) and its three updates in 2004, 2010, and 2015; (2) the 2020 IRP (currently in development); (3) the Water Shortage Contingency Plan (WSCP); (4) the Water Surplus and Drought Management (WSDM) Plan; (5) the Water Supply Allocation Plan (WSAP); (6) the Emergency Storage Objective; and (7) the Seismic Risk Assessment and Mitigation Plan. Collectively, they provide a policy framework, operating guidelines, and resource targets for MWD to ensure regional water supply reliability (MWD, 2022; WBMWD, 2021).
The IRP is MWD’s evolving long -term plan to assure adequate water supplies for Southern California. The first IRP was adopted in 1996 to address the complexity of developing, maintaining, and delivering water to meet changing demands in the face of growing challenges.
This version of the IRP was l ast update d in 2015 and detailed a series of reliability goals, approaches, and targets for each of their water resource areas, with some focus on maintaining existing capabilities and increasing net quantities over the 25 -year planning horizon (MWD, 2016). The 2015 IRP identified the following goals:
• Maintain Colorado River Aqueduct supplies;
• Stabilize State Water Project supplies;
• Achieve additional conservation savings; and
• Develop and protect local water supplies.
December 2024
EKI C40017.00
MWD
published annual implementation reports on its progress towards the 2015 IRP goals. The most recent Implementation Report (2019) highlighted the progress on achieving the resource and reliability goals established in the 2015 IRP as follows:
• MWD worked closely with other agencies to improve the reliability of its imported water supplies. MWD led efforts in crafting the Lower Colorado River Basin Drought Contingency Plan and supported efforts to make the Delta more resilient and support Governor Newsom’s direction to advance a single tunnel solution in the Delta. • MWD continued to support and encourage local supply development through the Local Resources Program. MWD’s board approved three projects with a total contract yield of 3,660 AFY from January 2019 to October 2019. As of October 2019, s even additional applications for a total of 116,580 AFY were under consideration. MWD was also assessing the water supply benefits from stormwater through pilot programs. • MWD continued to inform residents of water use efficiency through its ongoing advertising campaigns and education. In addition to rebates for water efficient fixtures, MWD also implement ed programs targeting outdoor conservation with its landscape education and turf replacement programs. In 2019, MWD ’s Board of Directors (Board)
approved a conservation initiative that focuses on reaching disadvantaged communities (MWD, 2019).
In 2020, MWD initiated a new IRP process with a fresh approach, looking at multiple scenarios that could play out in the future and how MWD could respond to maintain water reliability for the region. The 2020 IRP is a two -phase process including a Regional Needs Assessment (Phase 1) and a One Water Implementation phase (Phase 2). The Regional Needs Assessment was completed and adopted by the MWD Board in April 2022 , and includes the analysis of regional needs under a range of scenarios: (1) Scenario A, low demand and stable imports; (2) Scenario B, high demand and stable imports ; (3) Scenario C, low demand and reduced imports ; and (4) Scenario D, high demand and reduced imports (MWD, 2022). The Regional Needs Assessment found plausible reliability outcomes by the year 2045, with potential shortages ranging from no net shortage at all under Scenario A to as high as 1.2 million AF under Scenario D, and identifies needs and opportunities related to five focus areas: (1) SWP dependent areas ; (2) storage; (3) retail demand/ demand management ; (4) MWD imported supplies ; and (5) local supply. The Regional Needs Assessment concludes that:
Co
llectively, these findings instill a sense of optimism about Southern California’s water future. Metropolitan has identified the tools necessary to adapt to a variety of plausible futures successfully. It is also well within Southern California’s control to avoid a fate with increased per
-capi
ta water use and higher demands that would prove unsustainable.
December 2024
EKI C40017.00
Th
e Regional Needs Assessment further notes that through the One Water Phase of the process:
The precise combination of actions will emerge as more is known about the future that we actually face. Southern California is poised to be agile enough to adjust its portfolio of water actions to keep up with our changing times.
Completion of Phase 1 launched the beginning of the One Water Implementation (Phase 2). This phase, which is ongoing, involves collaboration between MWD’s Board, member agencies, and interested parties to establish a joint process for monitoring key reliability indicators, develop a coordinated approach to regional problems and resource needs identified in Phase 1, and create an adaptive management strategy (MWD, 2022).
While MWD coordinates regional supply planning through its inclusive IRP process, MWD’s member agencies also conduct their own planning analyses, including their own urban water management plans, and may develop projects independently of MWD (MWD, 2022; WBMWD, 2021).

As
shown in Figure 3, the majority of the GSWC Culver City service area overlies the Santa Monica Subbasin of the Los Angeles Basin (DWR Basin No. 4 -011.01; referred to as “Santa Monica Subbasin” or “Subbasin”).7
In 2020, 0.1 AF of groundwater pumped from the Santa Monica Subbasin was used by the GSWC Culver City service area (Table 5 ). However, GSWC does not anticipate using groundwater to meet demands for the Proposed Project or the rest of its GSWC Culver City service area within the 2045 planning horizon (GSWC, 2021; GSWC, 2022a ). Per the 2020 UWMP, while the GSWC Culver City service area has not relied upon groundwater to serve its customers over the last few years, GSWC maintains a well and may institute potential service from the Subbasin in the future upon completion of the Santa Monica Groundwater Subbasin GSP and implementing actions.
Although groundwater is not currently anticipated to supply the Propos ed Project, details regarding the Subbasin pursuant to CWC §10910(f) are provided below given the possibility that groundwater could be utilized in the future.
6.3.1 Basin Description
The following is a description of the groundwater basin from which the Proposed Project could be supplied, if GSWC uses its well in the future. The discussion is based on review of relevant information contained within the GSWC Culver City service area 2020 UWMP and the Santa Monica Groundwater Subbasin GSP (GSWC, 2021; SMBGSA, 2022).
The Santa Monica Subbasin comprises the northwestern part of the Coastal Plain of Los Angeles Groundwater Basin. It is bounded by impermeable rocks of the Santa Monica Mountains on the north and by the Ballona escarpment on the south. The Subbasin extends from the Pacific Ocean on the west to the Inglewood fault on the east. Ballona Creek is the dominant hydrologic feature and drains surface waters to the Pacific Ocean. The Subbasin is bounded to the south by the West Coast Subbasin and to the east by the Hollywood and Central Subbasins.
Holocene age alluvium forms much of the surficial deposits for the central part of the Subbasin and fills the Ballona gap, an erosional channel cutting into and across the Inglewood fault. These deposits include the clay-rich Bellflower aquiclude and underlying gravels of the Ballona aquifer.
Late Pleistocene alluvial sediments form much of the elevated plateau areas in the Subbasin and include older dune sands and the Lakewood Formation. The Lakewood Formation includes thin coarse-grained laterally discont inuous units in the Subbasin, not contiguous with the named aquifers of the Lakewood Formation elsewhere in the Los Angeles Basin. In general, groundwater supply wells are not screened within the Lakewood Formation. The Silverado aquifer within the early Pleistocene age San Pedro Formation is the main productive unit in the Subbasin in which the majority of the groundwater production wells in the basin are screened. Water bearing units 7 Small portions of the GWSC Culver City service area also overly the Central and West Coast Subbasins (DWR 4- 011.04 and DWR 4-011.03, respectively). However, GSWC’s Culver City service area well is located within the Santa Monica Subbasin.

be
low the San Pedro Formation include the Pliocene marine sediments of the Pico Formation, which are not widely produced.
The primary source of recharge to the Silverado aquifer (the primary productive unit within the Subbasin) is mountain front recharge from the Santa Monica Mountains to the north of the Subbasin. The Subbasin is highly urbanized and little recharge occurs via direct infiltration of precipitation in the Subbasin boundaries.
Primary sources of groundwater discharge from the Santa Monica Subbasin include groundwater production wells. Groundwater in the Santa Monica Subbasin moves mainly southward toward the Ballona gap, then flows toward to the ocean. Under normal water level c onditions, underflows are expected from the Santa Monica Subbasin to the West Coast Subbasin in the south. Relatively minor amounts of underflows are expected across the eastern boundary with the Hollywood and Central Subbasins or the western boundary with the ocean.

asin Status
Pursuant to CWC §10910f(2)(C), the Santa Monica Subbasin is not adjudicated and, in its recent evaluation of California groundwater basins, DWR determined that the Santa Monica Subbasin was not in a condition of critical overdraft (DWR, 2022).
The Santa Monica Subbasin is, however, designated as a medium priority basin under DWR’s 2019 Phase 2 Basin Prioritization (DWR, 2019). The main factors driving this designation include Population (5 out of 5 possible points), Population Growth (3 out of 5 possible points), and Total Wells (3 out of 5 possible points). Additional factors include Groundwater Reliance (2.5 out of 5 possible points), Public Supply Wells (2 out of 5 possible points), and Impacts (2 out of 5 possible points) (DWR, 2022).
As discussed in the Santa Monica Groundwater Subbasin GSP, a very small portion on the southern coastal edge of the Santa Monica Subbasin overlaps the adjudicated area of the West Coast Subbasin ( DWR 4-011.03). GSWC’s groundwater well is located outside of this area, and thus the adjudication does not impact potential groundwater use by the GSWC Culver City service area. Additional information on this adjudicated area is provided in the Santa Monica Groundwater Subbasin GSP (SMBGSA, 2022).
6.3.3 SGMA Groundwater Management
In 2014, the California State Legislature enacted the Sustainable Groundwater Management Act (SGMA) with subsequent amendments in 2015. SGMA requires the formation of Groundwater Sustainability Agencies (GSAs) and the development and implementation of GSPs for groundwater basins that are designated by DWR as medium or high priority. As a medium priority, non-critically overdrafted and non -adjudicated basin (see previous discussion), the Subbasin is subject to the requirements of SGMA, including the requirement to be covered by one or more GSAs and to prepare and submit to DWR one or more GSPs by 31 January 2022.
Per the Santa Monica Groundwater Subbasin GSP, the Santa Monica Basin Groundwater Sustainability Agency (SMBGSA) was formed in 2017. The five member agencies of the SMBGSA include the City of Santa Monica, the City of Beverly Hills, the City of Los Angeles (by and through its Department of Water and Power), the City of Culver City, and the County of Los Angeles. The five member agencies signed a Memorandum of Understanding for the formation of the SMBGSA in May 2017.
The Santa Monica Groundwater Subbasin GSP was submitted to DWR in 2022 and approved on 26 October 2023. DWR has recommended Corrective Actions to be addressed in the 2027 five - year GSP update. The GSP and DWR’s Determination Letter can be found on the DWR SGMA Portal: https://sgma.water.ca.gov/portal/gsp/preview/129. This GSP and subsequent updates will govern groundwater use within the Subbasin going forward.

EKI C40017.00
6.4 Recy
cled Water
Recycled water is not currently served to customers within the GSWC Culver City service area and is not expected to supply the Proposed Project. It is noted, however, that wastewater generated within the service area is treated by the City of Los Angeles, and a portion of that treated wastewater is sold to WBMWD for further treatment for recycled water uses throughout the WBMWD service area (GSWC, 2021). Although the GSWC Culver City service area does not directly utilize recycled water, its customers contr ibute to the regional water supply reliability benefit achieved through WBMWD’s distribution of recycled water.
6.5 Total Projected Potable Supply in Normal, Single Dry, and Multiple Dry Years As discussed above, water purchased from WBMWD constitutes the primary source of supply for the GSWC Culver City service area historically and is expected to be the sole source of supply within the 2045 planning horizon (GSWC, 2021). The WBMWD 2020 UWMP states that it will be able to serve 100% of projected demands in normal, single-dry and multiple-dry years (WBMWD, 2021). Because of this, GSWC expects that under all hydrologic conditions purchased water supplies will fully meet futur e purchased water dema nds included in the GSWC 2020 UWMP .
Additionally, GSWC has confirmed that it has the ability to purchase additional water from WBMWD to meet the additive demands of the other known developments and the Proposed Project (GSWC, 2024).
Therefore, the available supplies to the GSWC Culver City service area are considered to be equal to GSWC 2020 UWMP demands plus the additive demands of other known developments and the Proposed Project under all conditions (i.e., current and projected, and for normal, single dry, and multiple dry years including a five-year drought period).
The total projected potable supplies for the GSWC Culver City service area for normal, single dry, and multiple dry years are presented in Tables 6, 7, and 8.

7 COMPARISON OF SUPPLY AND DEMAND
Pursuant to CWC § 10910(c)(3), this WSA includes an estimate of the projected water supplies available to GSWC Culver City service area under normal, single dry, and multiple dry years, based on the 2020 UWMP, and a discussion of whether those supplies will meet the projected demand associated with the Proposed Project as well as the water system’s existing and planned future uses. This assessment is parallel to the multiple -dry year supply reliability analysis required for UWMPs under CWC §10635. In 2018, CWC §10635 was revised to require UWMPs to extend this analysis to consider “a drought lasting five consecutive water years.” Although the parallel WSA requirement (i.e., CWC §10910(c)(3)) has not been updated to require this for WSAs, a five-year drought scenario is also evaluated herein.
CWC § 10910 (c)(3)
If the projected water demand associated with the proposed project was not accounted for in the most recently adopted urban water management plan, or the public water system has no urban water management plan, the water supply assessment for the project shall include a discussion with regard to whether the public water system's total projected water supplies available during normal, single dry, and multiple dry water years during a 20-year projection will meet the projected water demand associated with the proposed project, in addition to the public water system's existing and planned future uses, including agricultural and manufacturing uses. CWC § 10911 (a)
If, as a result of its assessment, the public water system concludes that its water supplies are, or will be, insufficient, the public water system shall provide to the city or county its plans for acquiring additional water supplies, setting forth the measures that are being undertaken to acquire and develop those water supplies. If the city or county, if either is required to comply with this part pursuant to subdivision (b), concludes as a result of its assessment, that water supplies are, or will be, insufficient, the city or county shall include in its water supply assessment its plans for acquiring additional water supplies, setting forth the measures that are being undertaken to acquire and develop those water supplies. Those plans may include, but are not limited to, information concerning all of the following:
(1) The estimated total costs, and the proposed method of financing the costs, associated with acquiring the additional water supplies.
(2) All federal, state, and local permits, approvals, or entitlements that are anticipated to be required in order to acquire and develop the additional water supplies.
(3) Based on the considerations set forth in paragraphs (1) and (2), the estimated timeframes within which the public water system, or the city or county if either is required to comply with this part pursuant to subdivision (b), expects to be able to acquire additional water supplies. CWC § 10911 (c)
The city or county may include in any environmental document an evaluation of any information included in that environmental document provided pursuant to subdivision (b). The city or county shall determine, based on the entire record, whether projected water supplies will be sufficient to satisfy the demands of the project, in addition to existing and planned future uses. If the city or county determines that water supplies will not be sufficient, the city or county shall include that determination in its findings for the project.

Tab
les 6, 7, and 8 provide a comparison of the demands and supplies, inclusive of the Proposed Project and other known developments , in normal year, single -dry year, and multiple -dry year hydrologic scenarios for the GSWC Culver City service area. As discussed above, the available supplies to the GSWC Culver City service area are considered to be equal to GSWC Culver City service area 2020 UWMP demands plus the additive demands of other known developments and the Proposed Project under all conditions (i.e., current and projected, and for normal, single dry, and multiple dry years).
While supply shortfalls are not projected, any shortfalls that could occur in the future would be managed through the implementation of GSWC Culver City service area’s WSCP. The overall reduction goals in the WSCP are established for six drought stages ranging from 10% to greater than 50% shortfalls.
During the historic 2013 -2017 drought, the GSWC Culver City service area was subject to the State Water Resources Control Board’s ( SWRCB’s) mandatory water reduction target at 16% between June 2015 and May 2016,
8 and met its target through implementation of its WSCP and reducing its water demand 17% relative to its water use in 2013 (SWRCB, 2016). On 8 July 2021, in response to the recent drought conditions, Governor Newsom signed Executive Order ( EO) N-10-21 calling Californians to voluntarily reduce water use by 15% compared to 2020 levels. On 28 March 2022, following the driest first three months of a year in the S tate’s recorded history, Governor Newsom signed EO N-7-22 calling on local water suppliers to move to Stage 2 of their WSCP. GSWC enacted Stage 2 of its WSCP for the GSWC Culver City service area on 27 June 2022 and implemented numerous drought response actions, including, but not limited to, outdoor watering day restrictions and drought emergency surcharges for usage in excess of customer baseline (GSWC, 2021 ; GSWC, 2022b ). As a result of recent dramatic rainfall in 2023, GSWC moved the GSWC Culver City service area from Stage 2 to Stage 1 effective 14 May 2023 (GSWC, 2023). As a customer within the GSWC Culver City service area, the Proposed Project would be obligated to comply with any demand reduction efforts imposed by GSWC through implementation of the WSCP in any future water shortage conditions. Therefore, the Proposed Project would contribute a proportionate share of the reduction in water demands during dry years or other water shortage conditions.
In 2016, Governor Brown signed EO B-37-16 Making Water Conservation a California Way of Life and subsequently SB 606 and AB 1668 were passed. SB 606/AB 1688 set new requirements for urban water agencies to continue to increase water efficiency beyond the 2020 water use targets developed under the Water Conservation Act of 2009 (SB X7-7). Beginning in 2024, agencies are required to report on “urban water use objective” ( UWUO), which is based on an aggregate 8 On 5 May 2015, the SWRCB adopted Resolution 2015- 0032 that mandates minimum actions by water suppliers and their customers to conserve water supplies into 2016 and assigned a mandatory water conservation goal to each water supplier based on their residential gallons per capita per day (R-GPCD). The Resolution was adopted pursuant to Executive Order B -29-15 that directed SWRCB to impose mandatory restrictions on urban water suppliers to achieve a statewide 25% reduction in potable urban water usage to address California’s severe drought conditions.

es
timate of efficient urban water use for the previous year based on local service area characteristics for that year and the adopted water use efficiency standards for the previous year (DWR, 2023) . Additionally, agencies can adjust their UWUO’s by adding an allowable potable reuse bonus incentive under CWC §10609.20(d). Through comparing UWUOs from the previous to the current year, agencies are expected to be better equipped to eliminate unnecessary uses of water, resulting in continued increases in efficiency for all urban water suppliers in the State.
In addition, SB 606/AB 1668 add ed new requirements related to drought planning and WSCPs, including requirements for agencies to : (1) conduct a drought risk assessments part of their future UWMPs to assess water supply reliability (or vulnerability) for a period of drought lasting five consecutive water years (CWC §10635(b)), and (2) conduct annual water supply and demand assessments to determine its water supply reliability for the current year and one dry year (CWC §10632(a)). These elements are included in the GSWC Culver City service area 2020 WSCP (i.e., Chapter 6 of the 2020 UWMP).
Therefore, given that: (1) the projections inclusive of the Proposed Project do not identify supply shortfalls under any hydrologic conditions evaluated; (2) GSWC has the ability to implement the WSCP in the case of supply shortages, and demonstrated its effectiveness during recent droughts; and (3) the recent increasing efficiency and drought planning requirements from the State, sufficient water supply is estimated to be available to GSWC to meet all future demands within the GSWC Culver City service area including those associated with the Proposed Project.
December 2024
EKI C40017.00
8 CONCLUSIONS
As listed in CWC §10910(c)(4), the primary purpose of this WSA is to evaluate whether sufficient water supply is available to meet all future water demands within the water supplier’s service area, including those associated with the Proposed Project, during normal, single, and multiple dry hydrologic years for a 20-year time horizon.
As described in Section 4, the water demand of the Proposed Project (i.e., estimated at 237 AFY at buildout) has been conservatively estimated. As discussed in Section 5, the Proposed Project’s commercial and landscaping demands, and associated water distribution losses, are within the projected water demand growth that form the basis of GSWC’s demand projections in the adopted GSWC Culver City 2020 UWMP, while the multi -family residential and corresponding distributional loss demands are additive to the 2020 UWMP projections . GSWC has confirmed that it is able to purchase 100 % reliable water supply from WBMWD to meet these additive demands of the Proposed Project. In addition, GSWC, due to new requirements by the State, i s currently required to continue to increase water efficiency in its service area into the future .
GSWC has demonstrated effectiveness in reducing demand during recent water shortage conditions through implementation of its WSCP and would be expected to rely on its WSCP to meet any potential water shortages or regulatory-required cutbacks.
Therefore, this WSA concludes that sufficient water supply is available to GSWC to meet all future demands within the GSWC Culver City service area, including those associated with the Proposed Project.

The 10950 Washington Boulevard Project demands are provided per Reference 2.
The number of service connections for the Proposed Project associated with the multi-family residential use (orange) is greater than the anticipated growth indicated in the 2020 UWMP for the multi-family residential sector (blue). Because of this, it can be assumed that these demands are not included in the 2020 UWMP and are, therefore, additive to the demands of the 2020 UWMP.
The Culver Crossings Campus Building 1 Project demands are provided per Reference 3.
The number of service connections for the Proposed Project associated with the commercial use (orange) and landscaping use (orange) is less than the anticipated growth indicated in the 2020 UWMP for the commercial and landscaping sector (blue).
Because of this, it can be assumed that these demands are included in the 2020 UWMP.
