(Carollo) in accordance with the California Water Code (CWC) Section 10910-10912 for the Baker Street Project Planning Application No. 2020-103 referred herein as the Project. ES.1 Purpose The Project is a proposed industrial warehouse building planned to occupy approximately 66 acres of land and is therefore subject to Senate Bill (SB) 610 (the requirements of SB 610 are detailed in Section 1.1). A WSA is required and must address whether the projected water supply under normal, single dry, and multiple dry water years over a 20-year projection is adequate to meet the demand projected for the Project plus existing and planned future uses. ES.2 EVMWD Service Area EVMWD provides water services to two divisions: the Elsinore Division and the Temescal Division Service Area (TDSA), which includes the cities of Lake Elsinore and Canyon Lake, portions of Wildomar and Murrieta, and unincorporated Riverside County and Orange County land. EVMWD currently provides service to approximately 164,000 people and expects to serve nearly 240,000 people by 2045. The Project is located within the Elsinore Division. ES.3 Project Description The Project would consist of two new industrial warehouse buildings totaling 1,000,451 square feet on approximately 66 acres of land designated for limited industrial use. The Project is located at the southeast intersection of Baker Street and Pierce Street, south of Nichols Road, in the City of Lake Elsinore. ES.4 Demands Over the past five years, EVMWD used an average of 23,200 acre feet per year (AFY) of potable water. As part of its Urban Water Management Plan (UWMP), EVMWD analyzed several scenarios for potential future demands. Demands were developed using an annual growth rate of 1.5 percent, consistent with historical growth, and a population growth rate based on projections by the Southern California Association of Governments (SCAG). Both scenarios included an analysis based on gallons per capita per day (gpcd), and a 10 percent buffer was added to account for uncertainties. Ultimately, EVMWD elected to use a demand projection based on a 1.5 percent growth rate. The demand projections established in the 2020 UWMP include anticipated demand for planned developments. EVMWD included this Project as a planned development as Reference No. 364 in the 2020 UWMP. The anticipated demands for the Project are estimated to be 52 AFY, as shown in Table ES.1.

EVMWD also produces recycled water for landscape and golf course irrigation. EVMWD plans to use these supplies to meet current and future demands under normal, single dry, and five consecutive dry years. EVMWD plans to utilize existing local sources prior to imported water. In addition, EVMWD has identified several projects to increase reliability in all years. Future projects include well replacement, construction of new wells, treatment upgrades at CLWTP, and indirect potable reuse (IPR). EVMWD's anticipated future supplies are shown in Table ES.2.

EVMWD can purchase more water at an additional charge. (2) Starting in 2026, EVMWD plans to start purchasing about 3,700 AFY of raw imported water from Western/Metropolitan for treatment at the CLWTP. (3) In settlement of litigation, EVMWD agreed not to treat more than 8,000 AFY of San Jacinto River flows in any water year at EVMWD's CLWTP. This 8,000 AFY limit applies only to San Jacinto River runoff and excludes any imported water conveyed in the river channel. (4) In accordance with its National Pollutant Discharge Elimination System (NPDES) permit, EVMWD is permitted to discharging 0.5 million gallons per day (mgd) to Temescal Wash and 7.5 mgd to Lake Elsinore. EVMWD is planning to use excess wastewater collected at the Regional WRF to implement an IPR project. It is anticipated that this water will be available between 2035 and 2040. (5) Includes recycled water produced by the three EVMWD WRFs and recycled water from Santa Rosa Regional Resources Authority (SRRRA) and Eastern. ES.6 Supply and Demand Comparison EVMWD has a surplus of water to meet its projected demands, which include the anticipated demands of 52 AFY for the Project. Therefore, EVMWD's supplies are adequate to provide the Project demands. EVMWD has a diverse supply portfolio that provides operational flexibility and reliability. In 2020, EVMWD relied on local groundwater to meet about 36 percent of the potable demands, promoted the use of recycled water to offset potable water needs, and imported water to meet any remaining demands. EVMWD intends to continue promoting conservation, evaluating supplemental supplies, and participating in projects, when feasible, to ensure EVMWD's water supply sources are protected and sustainable throughout the future. To mitigate and adapt to unpredictable conditions, EVMWD will continue to diversify its local water supply portfolio. BAKER STREET WATER SUPPLY ASSESSMENT APRIL 2025 / FINAL / CAROLLO ELSINORE VALLEY MUNICIPAL WATER DISTRICT BAKER STREET WATER SUPPLY ASSESSMENT 1 SECTION 1 INTRODUCTION AND PURPOSE This WSA was prepared on behalf of the EVMWD by Carollo in accordance with the CWC Section 10910-10912 for the Baker Street Project Planning Application No. 2020-103, referred herein as the Project. This Section provides an overview of EVMWD and the Project. In 2001, the California Legislature enacted SB 610 (Chapter 643, Statutes of 2001) and SB 221 (Chapter 642, Statutes of 2001), which amended the CWC to improve the linkage between water supply planning and new development. As required by SB 610, EVMWD is responsible for determining if its total projected water supplies will meet the projected water demand for the Project, in addition to EVMWD's existing and planned future uses. The Project site has the existing land use designation of limited industrial under the General Plan and is currently vacant and undeveloped. The Project proposes the construction of two new industrial warehouse buildings totaling 1,000,451 square feet, along with auto and trailer parking areas. The Project area spans approximately 66 acres and is located within the County of Riverside (County). The County is the Lead Agency for the Project under the California Environmental Quality Act (CEQA) and has determined that the Project is subject to review under CEQA (Public Resources Code, Section 21000 et. seq.), and the state CEQA Guidelines (California Code of Regulations, Section 15000 et. seq.). EVMWD must provide the assessment results to the County for inclusion in the CEQA document for the Project. This section provides an overview of the law and purpose, EVMWD's service area, and the Project description. 1.1 Overview of the Law and Purpose Effective January 1, 2001, the California Legislature enacted SB 610 (CWC Section 10910), which requires water suppliers to prepare a WSA for certain new developments, and SB 221 (California Government Code Section 66473.7), which mandates that any agency approving a subdivision (as defined in the code) must include written evidence that an adequate water supply is available as a condition for approval. SB 610 and SB 221 are companion measures intended to promote more collaborative planning between local water suppliers and cities and counties. Both statutes require detailed information regarding water availability to be provided to the city and county decision-makers before approving any specified large development projects. Under SB 610, a water supplier must prepare a WSA for any project meeting specific size criteria and provide the results of the WSA to the Lead Agency for inclusion in the CEQA document. As defined in CWC Section 10912, a "project" is a development that is subject to CEQA and meets one of the following criteria: 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. BAKER STREET WATER SUPPLY ASSESSMENT APRIL 2025 / FINAL / CAROLLO ELSINORE VALLEY MUNICIPAL WATER DISTRICT BAKER STREET WATER SUPPLY ASSESSMENT 2 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. Per the California Government Code Section 66473.7, a "subdivision" means a proposed residential development of more than 500 dwelling units, except that for a public water system that has fewer than 5,000 service connections, "subdivision" means any proposed residential development that would account for an increase of 10 percent or more in the number of the service connections. Based on this definition, the Project is not subject to SB 221. The Project is subject to SB 610 because it is an industrial park planned to occupy more than 40 acres of land. A WSA must address whether the projected water supply under normal, single dry, and multiple dry water years is adequate to meet the demand projected for the Project plus existing and planned future uses. This WSA was prepared in accordance with SB 610 and includes the following:  Section 1 - Introduction and Purpose. This chapter provides an overview of the WSA requirements, EVMWD service area, and the Project.  Section 2 - Water Demands. This section describes EVMWD's existing and projected water demands.  Section 3 - Water Supplies. This section summarizes EVMWD's existing and projected water supplies.  Section 4 - Water Supply and Demand Analysis. This section compares demands and supplies under normal, single dry, and multiple dry water years to determine if supplies are adequate to meet the demand projected for the Project plus existing and planned future uses. The EVMWD's 2020 UWMP was reviewed as it serves as a foundational document for a WSA. In addition, the following documents and information were reviewed to assess whether the projected supplies are sufficient to meet the Project demand in addition to the existing and planned future demands:  2024 Water System Master Plan, prepared in April 2024.  2024 Sewer System Master Plan, prepared in May 2024.  Elsinore Valley Subbasin Groundwater Sustainability Plan (GSP), prepared in January 2022.  Bedford-Coldwater Subbasin GSP, prepared in November 2021.  EVMWD's planned developments tracking list.  Draft Integrated Resources Plan, prepared in January 2024. Based on a review of the aforementioned documents and information, the projected supplies were determined to be sufficient to meet the demands of planned developments, including the Project. Per Appendix H of the 2020 UWMP, the total estimated demand for planned developments was determined as approximately 12,800 AFY. This value was estimated using information about planned developments throughout the service area at the time, including the Project. As described in Section 2, the anticipated demand for the Project is 52 AFY. The demand projections in the UWMP account for the entire demand expected for the Project. BAKER STREET WATER SUPPLY ASSESSMENT APRIL 2025 / FINAL / CAROLLO ELSINORE VALLEY MUNICIPAL WATER DISTRICT BAKER STREET WATER SUPPLY ASSESSMENT 3 Since then, additional planned developments have been identified, with associated water demands estimated at approximately 2,490 AFY. Despite this increase in demand, the projected supplies from the 2020 UWMP remain sufficient to meet the total demand. 1.2 EVMWD Service Area EVMWD, a public nonprofit agency, was created on December 23, 1950, under the Municipal Water District Act of 1911. As a special district, EVMWD's powers include the provision of public water service, water supply development and planning, wastewater treatment and disposal, and recycling. Currently, EVMWD has over 48,772 water, wastewater, and agricultural service connections. EVMWD's service area has two divisions: the Elsinore Division and the TDSA. EVMWD's water service area includes the cities of Lake Elsinore and Canyon Lake, portions of Wildomar and Murrieta, and unincorporated Riverside County and Orange County land. A map of the service area is shown in Figure 1. The Elsinore Division makes up most of the service area, with approximately 48,050 active domestic connections, encompassing an area of 96 square miles. The TDSA is located northwest of the EVMWD service area and is a self-sustained water division, hydraulically separate from EVMWD. It covers an area of approximately 2.5 square miles and has approximately 722 connections. EVMWD currently obtains its water from 13 operating groundwater wells, the CLWTP, and imported water from Metropolitan through the Auld Valley Pipeline (AVP) and the Temescal Valley Pipeline (TVP). EVMWD currently operates three WRFs: Regional WRF, Horsethief Canyon WRF, and Railroad Canyon WRF. In addition, wastewater flow in the southern part of EVMWD's service area is treated at the Santa Rosa WRF owned and operated by the SRRRA. These four reclamation facilities serve four major service areas within EVMWD's wastewater collection system. Each service area consists of gravity collectors, trunk lines, lift stations, and force mains, which convey flow to the treatment plants. Effluent from all of these WRFs meets Title 22 disinfected tertiary standards and can be used for non-potable water supply to EVMWD's recycled water system. EVMWD's wastewater system is described in more detail in the 2024 EVMWD Sewer System Master Plan (Carollo, 2024a).
