WHEREAS, in periods of peace and prosperity and times of struggles and strife, countless individuals turn to prayer to seek guidance, bolster their faith, and brace their spirits when they need it most; and
WHEREAS, prayer is both a personal and communal act composed of our most intimate thoughts and practices observed by multitudes across our diverse Nation in every language, culture, religion, and belief system; and
WHEREAS, the right to pray is enshrined in our Constitution and stamped firmly in the American tradition by the belief that prayer moves mountains, a belief of making the impossible possible; and WHEREAS, throughout history, prayer has empowered moral movements and fueled efforts to strengthen democracy, deeply rooted in the fight to abolish slavery and the expansion of voting rights and voter access; and
WHEREAS, we will never fully understand how prayer has quietly influenced every aspect of individuals' lives — bringing comfort to service members on the battlefield, grounding the spirits of astronauts in space, guiding the healing hands of medical professionals tending to our loved ones, and fortifying the faiths of millions of worshippers in every corner of our Nation. There is hardly an aspect of American life that is not touched by the silent prayer supplications to fulfill our hopes and aspirations.

NOW, THEREFORE, I, Linda Krupa, Mayor of the City of Hemet, along with the Hemet City Council, hereby proclaim the month of June 2026 as:

WHEREAS, the Army has distinguished itself as a versatile and resilient force, fighting on the frontlines of battle, providing humanitarian aid, and supporting peacekeeping missions around the globe; and

WHEREAS, generations of soldiers have served with honor and distinction at home and abroad, ensuring peace, security, and humanitarian assistance across the globe; and
WHEREAS, we recognize the more than 700,000 soldiers currently serving and commend the commitment of our local veterans, service members, and military families who strengthen our community with their resilience and patriotism; and

City of Hemet
City Council Meeting

STAFF REPORT
Meeting: City Council Meeting - Jun 09 2026
Department: Public Works
Submitted by: Noah Rau, Interim City Manager
Travis Holyoak, Water/Waste Water Superintendent;
☐ Receive and File ☐ Consent Calendar ☐ Business Item ☒ Public Hearing TITLE:

Adoption of The City of Hemet 2025 Urban Water Management Plan and Water Shortage Contingency Plan pursuant to California Water Code §10610-10656 and §10608 RECOMMENDED ACTION:

It is respectfully requested that the City Council take the following actions:

1. Adopt the following resolution:

RESOLUTION NO. 2026-082 - A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF HEMET, CALIFORNIA, ADOPTING THE 2025 URBAN WATER MANAGEMENT PLAN AND THE

WATER SHORTAGE CONTINGENCY PLAN PURSUANT TO CALIFORNIA WATER CODE SECTIONS 10610 THROUGH 10656 AND SECTION 10608

2. Authorize the City Manager to approve the annual Water Supply and Demand Assessment each year.

BACKGROUND:

The City of Hemet owns and operates a municipal water production and distribution system that provides potable water service to residential and commercial customers within its service area. The system serves over 9,000 customer connections and provides approximately 3,800 acre-feet of water annually, with the majority of supply derived from locally sourced groundwater from the Hemet/San Jacinto Groundwater Basin.

In 1983, the State of California enacted the Urban Water Management Planning Act, which requires urban water suppliers serving more than 3,000 customers or supplying more than 3,000 acre-feet of water annually to prepare and adopt an Urban Water Management Plan (UWMP) every five years.

The UWMP is intended to support long-term water supply planning and demonstrate the reliability of water supplies under normal, single dry-year, and multiple dry-year conditions.

14.B.

The City’s most recent UWMP was adopted in July 2021. The 2025 UWMP represents the required five-year update and incorporates current water supply conditions, updated demand projections, and revised regulatory requirements.

ANALYSIS:

The 2025 Urban Water Management Plan (UWMP) has been prepared in accordance with the requirements of the California Water Code and reflects updated State guidance, including drought risk assessment, water supply reliability analysis, and water shortage contingency planning.

Unlike the previous UWMP, which was prepared by an external consultant, the 2025 UWMP was developed in-house by City staff. This approach allowed for greater integration of local system knowledge, improved coordination across departments, and reduced overall preparation costs.

The UWMP evaluates water supply and demand over a 25-year planning horizon in five-year increments. Population projections used in the Plan are based on service area-specific data and reflect the largely built-out nature of the City's water service area, resulting in relatively stable population growth over time.

The City's primary water supply consists of locally sourced groundwater from the Hemet/San Jacinto Groundwater Basin, including both pumped groundwater and City-owned groundwater conveyed through Eastern Municipal Water District (EMWD). The City also maintains connections to EMWD for access to treated imported water, which may be utilized as a supplemental supply during emergencies or periods of increased demand.

The UWMP confirms that the City has sufficient water supplies to meet projected demands under normal, single dry-year, and multiple dry-year conditions throughout the planning horizon. The Plan identifies the City's reliance on local groundwater resources as a key strength in maintaining longterm water supply reliability.

Included as part of the UWMP is the Water Shortage Contingency Plan (WSCP), which establishes six standardized water shortage levels and corresponding response actions to reduce water demand during supply shortages. The WSCP also includes procedures for conducting annual water supply and demand assessments, as required by State law.

The City coordinated with regional agencies, including Eastern Municipal Water District, surrounding jurisdictions, and regional water management organizations, as part of the UWMP development process. The draft UWMP was made available for public review in advance of adoption.

As required by the UWMP Guidebook, 60-day notices were distributed to surrounding cities and water agencies regarding the preparation of the City of Hemet's 2025 Urban Water Management Plan. In addition, public hearing notices were provided to surrounding cities and water agencies and were published in the local newspaper on May 26 and June 2, in accordance with the requirement that notices be published twice, with at least five days between publications, prior to the public hearing.

DISCUSSION:

City staff presented the Urban Water Management Plan to the Planning Commission on 5/19/2026 and received the following comments:

14.B.

 The Planning Commission would like future consideration for the feasibility to bring recycled water to areas of the water system that are currently using potable water to irrigate.

STRATEGIC PLAN INTEGRATION:

GOAL FIVE: ORGANIZATIONAL EFFECTIVENESS
To identify the work needed inside the City organization to effectively provide services to the community and ensure financial stability.

Objective 1: Operate in a financially sustainable manner.

Objective 2: Evaluate existing practices to ensure continuity with industry best practices.

Objective 3: Provide Council with policies that are consistent while lessening liabilities.

FISCAL IMPACT:

The 2025 Urban Water Management Plan was prepared in-house by City staff, resulting in cost savings compared to prior updates that utilized external consultants. There is no direct impact to the General Fund associated with adoption of the UWMP or WSCP.

ALTERNATIVE(S):

The City Council may elect not to adopt the UWMP; however, failure to adopt and submit the Plan would result in non-compliance with State law and may affect the City’s eligibility for certain State grant and funding opportunities.

Chapter 1 Introduction and Overview
An urban water supplier is defined (pursuant to Section 10617 of the California Water Code1) as “a supplier, either publicly or privately owned, providing water for municipal purposes either directly or indirectly to more than 3,000 customers or supplying more than 3,000 acre-feet of water annually. An urban water supplier includes a supplier or contractor for water, regardless of the basis of right, which distributes or sells for ultimate resale to customers.” The City of Hemet (City) is classified as an urban water supplier because it serves more than 3,000 customers (i.e. individual metered accounts) and it supplies more than 3,000 acre-feet of water annually to its customers for municipal purposes.

In accordance with the “Urban Water Management Planning Act”, which was enacted by the California Legislature in 1983, every urban water supplier (including the City) is required to prepare and adopt an Urban Water Management Plan (UWMP), periodically review its UWMP, and incorporate updated and new information into an updated UWMP at least once every five years.

The City’s most recent update was its 2020 UWMP (or 2020 Plan) which was submitted to, and approved by, the California Department of Water Resources (DWR). Urban water suppliers (including the City) are required to complete and submit their 2025 UWMPs to DWR by July 1st, 2026.

The current requirements for preparing the UWMP are included in California Water Code (CWC) Sections 10608 through 10657. The City’s 2025 UWMP (or 2025 Plan) was prepared consistent with the CWC and the recommended organization provided in DWR’s Final “Urban Water Management Plan Guidebook 2025” (Final 2025 UWMP Guidebook), dated January 2026.

The UWMP provides urban water suppliers (including the City) with a reliable management action plan for long-term resource planning to ensure adequate water supplies are available to meet existing and future water supply needs. In addition, the 2025 UMWP incorporates water supply reliability determinations resulting from potential prolonged drought, regulatory revisions, and/or changing climatic conditions.

CHAPTER 9: DEMAND MANAGEMENT MEASURES
CHAPTER 10: UWMP ADOPTION, SUBMITTAL, AND IMPLEMENTATION Pursuant to CWC requirements, the City’s 2025 Plan incorporates DWR’s water use and supply tables (standardized tables) for the reporting and submittal of UWMP data. DWR’s standardized tables are provided within the body of the 2025 Plan text as well as in Appendix A.

The City also submitted the UWMP data (standardized tables) electronically through DWR’s Online Submittal Tool.

14.B.

1-4
The City’s 2025 Plan also provides supporting documents (appendices) including notification letters of the Plan update, public notice of the Plan hearing, and adoption resolution from the City’s governing body. Further discussions regarding these supporting documents are provided within the individual Chapters of the City’s 2025 Plan.

1.2 UWMPS IN RELATION TO OTHER EFFORTS
The City is located within the service area of Eastern Municipal Water District (EMWD) and maintains interconnections that support water supply delivery, operational flexibility, and system reliability. Historically, the City has relied primarily on locally sourced groundwater and has utilized EMWD connections on a limited basis during emergency conditions or when local supplies are insufficient to meet demand.

Through its interconnections with EMWD, the City has access to treated imported water as well as the ability to convey City-owned groundwater supplies through EMWD’s regional system.

Imported water available through EMWD is supplied by the Metropolitan Water District of Southern California (MWD), which imports water from the Colorado River and the State Water Project.

In addition to access to imported supplies, the City utilizes EMWD’s infrastructure to convey groundwater from the Hemet/San Jacinto Basin to its distribution system. This process, commonly referred to as “wheeling,” allows the City to deliver locally owned groundwater supplies without relying on direct groundwater pumping within its service area. These wheeled supplies are considered part of the City’s local groundwater resources and are not classified as purchased or imported water.

EMWD has prepared its 2025 Urban Water Management Plan, which is incorporated into the City’s 2025 UWMP by reference. The City has coordinated with EMWD in the development of this Plan and has provided projected water demands in five-year increments under normal, single dry-year, and multiple dry-year conditions over the 25-year planning horizon.

1.3 UWMPS AND GRANT OR LOAN ELIGIBILITY

Pursuant to DWR’s Final 2025 UWMP Guidebook:
“In order for a Supplier to be eligible for any water grant or loan administered by DWR, the Supplier must have a current UWMP on file that has been determined by DWR to address the requirements of the Water Code. A current UWMP must also be maintained by the Supplier

14.B.

1-5
throughout the term of any grant or loan administered by DWR. A UWMP may also be required in order to be eligible for other state funding, depending on the conditions that are specified in the funding guidelines. Suppliers are encouraged to seek guidance on the specifics of any state funding source from the respective funding agencies. The following sections of the Water Code are pertinent to Suppliers considering pursuit of grants or loans.” The City’s 2025 Plan has been prepared to meet eligibility requirements for grants and loans administered by the State and/or DWR.

1.4 DEMONSTRATION OF CONSISTENCY WITH THE DELTA PLAN FOR

PARTICIPANTS IN COVERED ACTIONS
Pursuant to DWR, an urban water supplier that anticipates participating in or receiving water from a proposed project (or “covered action”) such as a multi-year water transfer, conveyance facility, or new diversion that involves transferring water through, exporting water from, or using water in the Sacramento-San Joaquin Delta should provide information in their 2020 and 2025 UWMPs for use in demonstrating consistency with Delta Plan Policy WR P1, “Reduce Reliance on the Delta Through Improved Regional Water Self-Reliance”. In addition, pursuant to California Code of Regulations, Title 23, § 5003:
(c)(1) Water suppliers that have done all of the following are contributing to reduced reliance on the Delta and improved regional self-reliance and are therefore consistent with this policy:
(A) Completed a current Urban or Agricultural Water Management Plan (Plan) which has been reviewed by the California Department of Water Resources for compliance with the applicable requirements of Water Code Division 6, Parts 2.55,

2.6, and 2.8;
(B) Identified, evaluated, and commenced implementation, consistent with the implementation schedule set forth in the Plan, of all programs and projects included in the Plan that are locally cost effective and technically feasible which reduce reliance on the Delta; and
(C) Included in the Plan, commencing in 2020, the expected outcome for measurable reduction in Delta reliance and improvement in regional self-reliance. The expected outcome for measurable reduction in Delta reliance and improvement in regional self-reliance shall be reported in the Plan as the reduction in the amount of water used, or in the percentage of water used, from the Delta watershed. For the purposes of reporting, water efficiency is considered a new source of water supply, consistent with Water Code section 1011(a).

14.B.

1-6
The City has reduced its reliance on imported water supplies for CY 2020 and CY 2025. In addition, the City is projected to continue reducing its reliance on imported water supplies through CY 2050. A further discussion which demonstrates the City’s measurable reduction in imported water reliance and improvement in regional self-reliance is provided in Appendix B.

Chapter 2 Plan Preparation and
Implementation
OVERVIEW – CHAPTER 2
Chapter 2 (Plan Preparation) of the City’s 2025 Plan discusses and provides the following:
• The basis for preparing an Urban Water Management Plan is provided. The City is required to prepare the 2025 Plan because it is an “urban water supplier” (the City serves more than 3,000 customers and it supplies more than 3,000 acre-feet of water annually to its customers for municipal purposes)
• The City is a “Public Water System” and is regulated by the State Water Resources Control Board - Division of Drinking Water. The City’s Public Water System number is provided in Table 2-1.
• The City’s Plan has been prepared as an “individual” plan rather than a “regional” plan in an effort to provide information specific to the City to best inform its employees, management and customers.
• Information presented in the City’s 2025 Plan is provided on “calendar year” basis. • Water quantities presented in the City’s 2025 Plan are provided on an “acre-foot” basis. • The City’s coordination and outreach efforts with wholesale water agencies, other retail water agencies, and the community are described. The City coordinated the preparation of its 2025 Plan with the Eastern Municipal Water District, Lake Hemet Municipal Water District, and the Santa Ana Watershed Project Authority. • The City’s notification process to the cities and county within which the City provides water supplies to is discussed.

2.1 PLAN PREPARATION
The City’s 2025 Plan (which includes the City’s 2025 Water Shortage Contingency Plan (WSCP) is considered an update to the City’s 2020 Plan. However, the 2025 Plan and the WSCP are considered stand-alone documents. As discussed in Section 1.1, the City’s 2025 Plan was prepared consistent with the recommended organization provided in DWR’s Final 2025 UWMP Guidebook:

14.B.

2-2
“The California Water Code (Water Code) specifies several requirements for preparing a UWMP, including who is required to prepare a UWMP; how to prepare a UWMP, depending on whether the Supplier choses to participate in a regional or individual planning effort; selection of reporting year-type; and coordination, notification, and outreach.” Pursuant to California Water Code requirements, the City’s 2025 Plan incorporates DWR’s water use and supply tables (standardized tables) for the reporting and submittal of UWMP data.

2.2 BASIS FOR PREPARING A PLAN
CWC 10617.
"Urban water supplier" means a supplier, either publicly or privately owned, providing water for municipal purposes either directly or indirectly to more than 3,000 customers or supplying more than 3,000 acre-feet of water annually. An urban water supplier includes a supplier or contractor for water, regardless of the basis of right, which distributes or sells for ultimate resale to customers. This part applies only to water supplied from public water systems subject to Chapter 4 (commencing with Section 116275) of Part 12 of Division 104 of the Health and Safety Code.

CWC 10620.
(b) Every person that becomes an urban water supplier shall adopt an urban water management plan within one year after it has become an urban water supplier.

CWC 10621.
(a) Each urban water supplier shall update its plan at least once every five years on or before July 1, in years ending in six and one, incorporating updated and new information from the five years preceding each update.

The City’s 2025 Plan was prepared in accordance with the UWMP Act which was established in 1983. The UWMP Act requires every “urban water supplier” to prepare and adopt a Plan, to periodically review its Plan at least once every five years and make any amendments or changes which are indicated by the review. An “Urban Water Supplier” is defined as a supplier, either publicly or privately owned, providing water for municipal purposes either directly or indirectly to more than 3,000 customers or supplying more than 3,000 acre-feet (AF) of water annually.

Section 10621(a) of the CWC states, “Each urban water supplier shall update its plan at least once every five years on or before July 1, in years ending in six and one, incorporating updated and new

14.B.

2-3
information from the five years preceding each update”. As a result, DWR requires the 2025 Plans be submitted by July 1, 2026.

The City is an “urban water supplier” pursuant to Section 10617 of the CWC and directly serves potable water to more than 3,000 customers and supplies more than 3,000 acre feet per year (AFY) at retail for municipal purposes. The City’s 2025 Plan is an update to the City’s 2020 Plan.

2.2.1 PUBLIC WATER SYSTEMS
CWC 10644.
(a)(2) The plan, or amendments to the plan, submitted to the department … shall include any standardized forms, tables, or displays specified by the department.

California Health and Safety Code 116275.
(h) "Public water system" means a system for the provision of water for human consumption through pipes or other constructed conveyances that has 15 or more service connections or regularly serves at least 25 individuals daily at least 60 days out of the year.

Pursuant to CWC requirements, the City’s 2025 Plan incorporates DWR’s standardized tables for the reporting and submittal of UWMP data. The standardized tables are provided within the body of the 2025 Plan text as well as in Appendix A. The City also submitted the UWMP data (from the standardized tables) electronically through DWR’s Online Submittal Tool.

In addition, the City is a Public Water System and is regulated by the State Water Resources Control Board - Division of Drinking Water (SWRCB-DDW). The SWRCBDDW requires water agencies provide the number of connections, water usage, and other information annually. The information provided to SWRCB-DDW indicates the City serves potable water to more than 3,000 customers and supplies more than 3,000 AFY. Table 2-1 provides the City’s Public Water System name and number.

2.2.2 SUPPLIERS SERVING MULTIPLE SERVICE AREAS/ PUBLIC WATER SYSTEMS The City serves only a single Public Water System. Table 2-1 provides the City’s Public Water System name and number.

uses within the existing or anticipated service area affecting the supplier’s water management planning. Urban water suppliers shall coordinate with local or regional land use authorities to determine the most appropriate land use information, including, where appropriate, land use information obtained from local or regional land use authorities, as developed pursuant to Article 5 (commencing with Section 65300) of Chapter 3 of Division 1 of Title 7 of the Government Code.

The City owns and operates a water distribution system that serves a portion of the City of Hemet. The City’s service area covers approximately 5.25 square miles (approximately 19 percent of the City’s municipal boundaries) and is located in the southwesterly part of Riverside County.

It is generally bounded on the north by the City of San Jacinto and the west by the City of Menifee.

The area surrounding the City is predominantly rural and supports farming and agricultural activity. The location of the City’s water service area is shown on Figure 10-1.

The City relies almost exclusively on groundwater pumped by its groundwater wells. The City’s three active wells (Wells 2A, 10A, and 12) produce groundwater from the San Jacinto Basin which covers an area of approximately 60 square miles. The San Jacinto Basin is drained by the San Jacinto River and is recharged by surface runoff from adjacent mountains and hills, by rainfall directly on the valley floor and by return flow from water applied from overlying uses. The San Jacinto Basin serves as a natural storage reservoir and filtering system for wells constructed therein. In addition, the San Jacinto Basin has a Groundwater Replenishment Program which uses untreated imported water to recharge the San Jacinto Basin.

3.2 SERVICE AREA BOUNDARY MAPS
As discussed in Section 3.1, the City’s service area covers approximately 5.25 square miles (approximately 19 percent of the City’s municipal boundaries). A service area boundary map is provided on Figure 10-1. The City’s water service area boundary, relative to the vicinity municipal boundary, is also provided in Figure 10-2.

The City’s service area map was submitted online through DWR’s Population Tool in a “KML” file format (i.e. Google Earth format). The KML file was originally created in a Geographical Information Systems (GIS) shape file format and converted into a KML format. To the extent information was available, metadata was included in the KML file (including map projection, contact information, start and end dates for which the map is valid, constraints, attribute table definitions, and digitizing base).

3.3 SERVICE AREA CLIMATE
CWC 10631.
(a) Describe the service area of the supplier, including … climate… CWC 10630.

It is the intention of the Legislature, in enacting this part, to permit levels of water management planning commensurate with the numbers of customers served and the volume of water supplied, while accounting for impacts from climate change.

The monthly historical average temperatures (including minimum and maximum), monthly historical average rainfall, and monthly evapotranspiration in the vicinity of the City’s service area is summarized in the tabulation below. Historical climate information was obtained from the Western Regional Climate Center (WRCC) and from DWR’s California Irrigation Management Information System (CIMIS).

The historical average rainfall in the vicinity of the City’s service area is 11.44 inches. The City’s service area in the San Jacinto Valley has a dry climate and summers can reach maximum average daily temperatures in the high 90s. Although changes in climatic conditions may have an impact (as discussed in Section 4.5), the projected water supply demands will be based on an average year, a single dry year and a five consecutive year drought, based on historical data and projected demands. Precipitation within the vicinity of the City’s service area is discussed further in Section

7.2.

Historical monthly average ETo information was obtained from the California Irrigation Management Information Systems (http://wwwcimis.water.ca.gov) and is based on data collected from Station 239 (Hemet).

A discussion of the City’s sources of supply, how those sources may be impacted by climate change, and the proactive actions the City and other local/regional water managers may take to address the potential climate change on water supplies is provided in Section 4.5.

3.4 SERVICE AREA POPULATION AND DEMOGRAPHICS

3.4.1 SERVICE AREA POPULATION
CWC 10631.
(a) Describe the service area of the supplier, including current and projected population… The projected population estimates shall be based upon data from the state, regional, or local service agency population projections within the service area of the urban water supplier and shall be in five-year increments to 20 years or as far as data is available.

The City provides water service to an area with a current population of 33,591. Table 3-1 presents the current and projected population within the City’s water service area from Calendar Year (CY)

14.B.

3-15
2025 through CY 2045. The service area population is projected to reach approximately 33,859 by CY 2045.

The City initially reviewed the California Department of Water Resources (DWR) Population Tool and available historical data to determine an appropriate methodology for developing population projections. While the DWR Population Tool provided a reliable historical baseline through 2020, showing a steady growth trend of approximately 0.37% to 0.40% per year, the City required more granular, real-time data to project beyond the 2020 Census cycle. Ultimately, the City determined that utilizing Esri Business Analyst datasets provided the most accurate and service area-specific estimates for the 2025-2045 planning horizon. Population and demographic data were derived using 2022 baseline conditions and 2026 real time information, with the analysis geographically defined to align with the City’s potable water service area boundary. This approach ensures that population estimates reflect only those areas served by the City’s water system.

This methodology is consistent with prior planning assumptions and with the City’s General Plan land-use designations. In the 2020 Urban Water Management Plan, the City evaluated regional growth projections prepared by the Southern California Association of Governments (SCAG) Connect SoCal 2020 Regional Transportation Plan / Sustainable Communities Strategy of the SCAG (2020-2045 RTP/SCS) which at the time utilized a 0.37% annual growth rate. The current 2025 UWMP updates those assumptions to the latest adopted SCAG Connect SoCal 2024 Regional Transportation Plan / Sustainable Communities Strategy (2024–2050 RTP/SCS) and its Demographics & Growth Forecast Technical Report (adopted April 4, 2024). These regional projections, together with the City of Hemet General Plan and the service area’s largely built-out condition, continue to indicate that population growth within the water service area will remain limited.

While the broader City of Hemet and Riverside County have experienced moderate population growth in recent years (averaging approximately 1 percent annually following the high-growth decades of the late 20th century), SCAG’s 2024 forecast reflects a region-wide transition to slower growth with steady improvement in housing production. Consistent with this broader trend and the City’s General Plan, the City’s water service area exhibits a substantially lower rate of change. The service area population is estimated at approximately 33,600 in 2026, representing a slight decrease from 2022 levels. Esri projections estimate a modest annual increase of approximately 0.04 percent through the planning horizon. This figure is remarkably consistent with the low-growth trends observed in the DWR tool and previous planning cycles, though slightly more conservative to reflect current economic and land-use constraints. This lowgrowth assumption reflects the limited development capacity within the service area, where minimal vacant land and few opportunities for large-scale expansion constrain future population increases.

As a result, population changes within the service area are expected to occur incrementally through infill development and redevelopment rather than outward expansion. Accordingly, the

14.B.

3-16
service area population is projected to remain relatively stable over the planning horizon. This conservative, data-driven assumption—reconciled to SCAG jurisdiction-level forecasts and the City’s General Plan—provides a reasonable and reliable basis for forecasting future water demands in the UWMP.

3.4.2 OTHER SOCIAL, ECONOMIC, AND DEMOGRAPHIC FACTORS
CWC 10631.
(a) Describe the service area of the supplier, including… other social, economic, and demographic factors affecting the supplier’s water management planning.

A discussion of water demand for lower income households within the City’s service area is provided in Section 4.4. No other demographic factors affect the City’s water management planning. However, increased population will have an impact on water demand.

3.5 LAND USES WITHIN SERVICE AREA
CWC 10631.
(a) The description shall include the current and projected land uses within the existing or anticipated service area affecting the supplier’s water management planning. Urban water suppliers shall coordinate with local or regional land use authorities to determine the most appropriate land use information, including, where appropriate, land use information obtained from local or regional land use authorities.

14.B.

3-17
The City reviewed the current and projected land uses within its service area during the preparation of this 2025 Plan. Information regarding current and projected land uses is included in the City’s General Plan 2030. The existing land uses within the City’s service area include residential (single-family and multi-family), commercial, institutional/governmental and landscape (open space). The projected land uses within the City’s service area are expected to remain similar to the existing land uses. In addition, although mostly built-out, the projected population within the City’s service area is anticipated to increase (as discussed in Section 3.4). A discussion of the existing and projected water uses for the individual water use sectors within the City’s service area, which includes the different land uses, is provided in Section 4.2. As discussed in Section 2.6, the City coordinated the preparation of the 2025 Plan with the City of Hemet, the City of San Jacinto, and other agencies.

As discussed in Section 3.4, the City obtained data from the Southern California Association of Governments document entitled “The 2024-2050 Regional Transportation Plan / Sustainable Communities Strategy of the SCAG", dated April 2024. Projected populations in the City’s service area were based on growth rate projections developed by SCAG. The data provided by SCAG incorporates demographic trends, existing land use, general plan land use policies, and input and projections through the year 2050 from the Department of Finance and the US Census Bureau for counties, cities, and unincorporated areas within Southern California.

Chapter 4 Water Use Characterization
OVERVIEW – CHAPTER 4
Chapter 4 (Water Use Characterization) of the City’s 2025 Plan discusses and provides the following:
• The City provides water service to individual “water use sectors”. These water use sectors include single-family residential, multi-family, commercial, institutional (and governmental), and landscape. Individual descriptions for these water use sectors are provided in Section 4.2.1.
• The City’s total water demands (including potable and recycled water) over the past 10 years have ranged from 3,636 AFY to 4,015 AFY, with an average of 3,826 AFY.

The City currently measures its water use through meter data and billing records. • The City conducts an annual water loss audit to identify distribution system water losses.

Water losses can result from pipeline leaks and inaccurate metering due to faulty meters.

Water loss estimates are incorporated into the City’s projected water demands. • The City’s projected water demands are provided in five-year increments over the next 25 years are provided (through Calendar Year 2050) as shown on Table 4-2. • The City’s water demand projections incorporate water savings which are the result of implementation of new plumbing codes along with consumer awareness of the need to conserve water.
• The projected water demands for lower income households are identified and are included in the City’s total projected water demands
• The City’s sources of water supply and how those sources may be impacted by climate change are discussed. The proactive actions the City and other local/regional water managers may take to address the potential climate change impacts on water supplies are also discussed.
• The City will be able to provide sufficient water supplies to meet the projected water demands of its customers, including during a five consecutive year drought period. • The City’s 2025 AWWA Water Loss Audit (FY 2024–2025) shows progress toward 2028 State standards, supported by ongoing efforts to improve data accuracy and system reliability through upgraded billing software and meter calibration.

4.1 NON-POTABLE VERSUS POTABLE WATER USE
The Water Code requires a description and quantification of water uses within the City’s service area, including both non-potable and potable water. The City has no current recycled water (nonpotable) demands as addressed in Section 6.2.5; however, a summary is provided in Table 4-1.

Furthermore, Chapter 4 addresses the City’s potable water demands.

4.2 PAST, CURRENT, AND PROJECTED WATER USES BY SECTOR
CWC 10635.
(a) Every urban water supplier shall include, as part of its urban water management plan, an assessment of the reliability of its water service to its customers during normal, dry, and multiple dry water years. This water supply and demand assessment shall compare the total water supply sources available to the water supplier with the long-term total projected water use over the next 20 years, in five-year increments, for a normal water year, a single dry water year, and a drought lasting five consecutive water years.

The water service reliability assessment shall be based upon the information compiled pursuant to Section 10631, including available data from state, regional, or local agency population projections within the service area of the urban water supplier.

CWC 10631.
(d)(1) For an urban retail water supplier, quantify, to the extent records are available, past and current water use, over the same five-year increments described in subdivision (a), and projected water use, based upon information developed pursuant to subdivision (a), identifying the uses among water use sectors, including, but not necessarily limited to, all of the following…
(2) The water use projections shall be in the same five-year increments described in subdivision (a).
(4)(A) Water use projections, where available, shall display and account for the water savings estimated to result from adopted codes, standards, ordinances, or transportation and land use plans identified by the urban water supplier, as applicable to the service area.

4-3
i. Provide citations of the various codes, standards, ordinances, or transportation and land use plans utilized in making the projections.
ii. Indicate the extent that the water use projections consider savings from codes, standards, ordinances, or transportation and land use plans. Water use projections that do not account for these water savings shall be noted of that fact.

The City’s current and projected water demands are provided in five-year increments over the next 25 years (through CY 2050) in Tables 4-1 and 4-2. The City’s total water demands were projected based on a review of the SB X7-7 calculations which are discussed in Chapter 5 (including the SB X7-7 water use target for 2020), current water use factors based on recent water demands, and the total population projections based on land use trends within the City.

The City provides water service to individual “water use sectors” as identified by the California Water Code. The water use sectors supplied by the City are discussed in Section 4.2.1. The water use for each of these sectors during CY 2025 is provided in Table 4-1. The projected water use for each individual water use sector is provided in Table 4-2 and is based on the percentage breakdown of water use from each individual water use sector in CY 2025 (the percentages were then applied to the projected total water use).

j) Distribution system water loss.

As shown in Table 4-1, the City’s service area includes the following water use sectors listed in the California Water Code:
• Single-family residential
(A single-family dwelling unit is a lot with a free-standing building containing one dwelling unit that may include a detached secondary dwelling. Single-family residential water demands are included in retail demands.)
• Multi-family
(Multiple dwelling units are contained within one building or several buildings within one complex. Multi-family residential water demands are included in retail demands.) • Commercial
(Commercial users are defined as water users that provide or distribute a product or service)
• Institutional (and governmental)
(Institutional users are defined as water user dedicated to public service. Institutional users include, among other users, higher education institutions, schools, courts, churches, hospitals, government facilities, and nonprofit research institutions.) Institutional accounts are included under the Commercial water use sector in Table 4-1. • Landscape
(Landscape connections supply water solely for landscape irrigation. Landscapes users may be associated with multi-family, commercial, industrial, or institutional/governmental sites, but are considered a separate water use sector if the connection is solely for landscape irrigation. Landscape water demands are included in retail demands.)
• Distribution system losses
(Distribution system losses represent the potable water losses from the pressurized water distribution system and water storage facilities, up to the point of delivery to the customers. Additional information is discussed in Section 4.2.4)

14.B.

4-6

4.2.2 WATER USE SECTORS IN ADDITION TO THOSE LISTED IN WATER CODE The City’s service area does not include other water demand sectors which are not listed in the California Water Code (including exchanges, surface water augmentation, transfers, wetlands or wildlife habitat).

4.2.3 PAST WATER USE
Chapter 6 provides a discussion of the sources of water supply the City uses to meet its water demands. Section 6.1 provides a tabulation of the City’s historical annual water demands for each water supply source. Over the past ten years, the City’s total water demands have ranged from 3,636 AFY to 4,015 AFY, with an average of 3,826 AFY. In addition, the City recently experienced a five consecutive year drought within its service area from CY 2011 to CY 2015.

The City reviewed its historical water demands to determine the projected water demands and water supply reliability (discussed in Chapter 7). The City is able to provide sufficient water supplies to meet the projected water demands of its customers, including during a five consecutive-year drought period.

4.2.4 DISTRIBUTION SYSTEM WATER LOSS
CWC 10631.
(d)(1) For an urban retail water supplier, quantify, to the extent records are available, past and current water use, over the same five-year increments described in subdivision (a), and projected water use, based upon information developed pursuant to subdivision (a), identifying the uses among water use sectors, including, but not necessarily limited to, all of the following…(J) Distribution system water loss.

CWC 10631.
(3)(A) The distribution system water loss shall be quantified for each of the five years preceding the plan update, in accordance with rules adopted pursuant to Section 10608.34.
(B)The distribution system water loss quantification shall be reported in accordance with a worksheet approved or developed by the department through a public process. The water loss quantification worksheet shall be based on the water system balance methodology developed by the American Water Works Association.

14.B.

4-7
(C)In the plan due July 1, 2021, and in each update thereafter, data shall be included to show whether the urban retail water supplier met the distribution loss standards enacted by the board pursuant to Section 10608.34.

Distribution system water losses represent the potable water losses from the pressurized water distribution system and water storage facilities, up to the point of delivery to the customers.

Sources of distribution system water loss can include: inaccurate metering due to faulty meters; water use not metered such as firefighting, flushing of the water system; and pipeline leaks.

The California Water Code Section 10608.34 requires “On or before October 1, 2017, and on or before October 1 of each year thereafter, each urban retail water supplier shall submit a completed and validated water loss audit report for the previous calendar year or the previous fiscal year...” The water loss audits must follow American Water Works Association (AWWA) guidance and be validated by a certified water audit validator. The City has completed the annual water loss audit process through October 1, 2025, as required by the California Water Code (i.e. the City has completed water loss audits representing calendar years 2020, 2021, 2022, 2023, and 2024). The City’s water loss audits were prepared and validated pursuant to DWR requirements. The annual water loss audit reports submitted by retail water agencies in California, including the City (provided in Appendix E), are available on DWR’s website (https://wuedata.water.ca.gov/awwa_plans).

The City’s annual water loss audits identify real water losses (e.g. leaks and main failures) and apparent water losses (e.g. customer meter inaccuracies, systematic data handling errors in customer billing systems, and unauthorized consumption). The City’s distribution system’s water losses are based on the sum of the real and apparent water losses. Table 4-5 presents the submittal status of the water loss audits for the past five years, including a link to the City’s submitted reports in the Notes section.

14.B.

4-8
Table 4-5 Water Loss Audit Reporting
The California Water Code Section 10608.34 directs the SWRCB to “adopt rules requiring urban retail water suppliers to meet performance standards for the volume of water losses.” Pursuant to this law, and as discussed above, urban retail water suppliers (including the City) have been submitting water loss audits to DWR annually since October 2017. Pursuant to Assembly Bill (AB) 1668 and (SB) Senate Bill 606, urban retail water suppliers are required to calculate an “urban water use objective”, which includes indoor, outdoor, commercial, industrial and institutional irrigation uses and allowed system water loss by the year 2024. In addition, by calendar year 2028, urban retail water suppliers are required to comply with individual volumetric standards (based on an economic model) for leak detection and repair actions. The goal of the proposed water loss standards is to reduce collective water losses throughout California by approximately 40 percent. The City will continue to develop its water loss standard and urban water use objective pursuant to SWRCB requirements.

14.B.

4-9

4.2.5 CURRENT WATER USE
The City currently measures its water use through meter data and billing records. The water use for the City’s individual water use sectors during CY 2025 are provided in Table 4-1. Recycled water uses are addressed separately in Chapter 6. The City’s total water uses during CY 2025 have been reviewed for compliance with the SB X7-7 water use targets for 2020 which were adopted in the City’s 2020 Urban Water Management Plan (discussed in Section 5.5).

DWR has created an optional “Planning Tool Worksheet” for water suppliers to review and assess monthly water use trends. DWR has deemed the tool as optional and the City is not required by DWR to use the tool. Section 6.1 provides a tabulation of the City’s historical annual water uses for each water supply source. During the past 10 years, the City experienced a five consecutive year drought within its service area from CY 2011 to CY 2015. Historical records indicate the City’s annual water demands had been greater prior to CY 2011. The City has been able to provide sufficient water supplies to its customers, including during five consecutive year droughts and years with historically high water demands. In addition, the City has been able to provide water service to meet maximum day water demands for these years, including during the summer months. A further discussion regarding the reliability of the City’s water supply sources is provided in Chapter 7.

4.2.6 PROJECTED WATER USE
CWC 10635.
(a) Every urban water supplier shall include, as part of its urban water management plan, an assessment of the reliability of its water service to its customers during normal, dry, and multiple dry water years. This water supply and demand assessment shall compare the total water supply sources available to the water supplier with the long-term total projected water use over the next 20 years, in five-year increments, for a normal water year, a single dry water year, and a drought lasting five consecutive water years. The water service reliability assessment shall be based upon the information compiled pursuant to Section 10631, including available data from state, regional, or local agency population projections within the service area of the urban water supplier.

CWC 10631.
(h)An urban water supplier that relies upon a wholesale agency for a source of water shall provide the wholesale agency with water use projections from that agency for that source of water in five-year increments to 20 years or as far as data is available. The wholesale

14.B.

4-10
agency shall provide information to the urban water supplier for inclusion in the urban water supplier’s plan that identifies and quantifies, to the extent practicable, the existing and planned sources of water as required by subdivision (b), available from the wholesale agency to the urban water supplier over the same five-year increments, and during various water-year types in accordance with subdivision (f). An urban water supplier may rely upon water supply information provided by the wholesale agency in fulfilling the plan informational requirements of subdivisions (b) and (f).

CWC 10631.
(d)(4)(A) Water use projections, where available, shall display and account for the water savings estimated to result from adopted codes, standards, ordinances, or transportation and land use plans identified by the urban water supplier, as applicable to the service area.
(d)(4)(B) To the extent that an urban water supplier reports the information described in subparagraph (A), an urban water supplier shall do both of the following:
(i)Provide citations of the various codes, standards, ordinances, or transportation and land use plans utilized in making the projections.
(ii) Indicate the extent that the water use projections consider savings from codes, standards, ordinances, or transportation and land use plans. Water use projections that do not account for these water savings shall be noted of that fact.

The City’s projected water demands are provided in five-year increments over the next 20 years (through CY 2050) in Table 4-2. The City’s projected water demands and water supplies during a normal year, a single dry year, and a five consecutive year drought are provided in Chapter 7. The projected water demands for each of the City’s water use sectors are provided in Table 4-2.

The City’s water demands were projected based on a review of the SB X7-7 calculations discussed in Chapter 5 (including the SB X7-7 water use targets that were adopted for 2020 and used for the 2025 Urban Water Management Plan Preparations), existing water use factors based on recent water demands, and the total population projections based on land use trends within the City. The projected water demands for the water use sectors were based on the percentage breakdown of water demands from each individual water use sector in CY 2025 (the percentages were then applied to the projected total water demands). A discussion of the City’s water supplies from EMWD, a wholesaler, are discussed in Section 6.2. As discussed in Section 2.6, the City has coordinated its water demand projections with EMWD for each water use sector.

The City’s water demand projections incorporate water savings, or “passive savings”, which are

14.B.

4-11
the result of implementation of new plumbing codes along with consumer awareness of the need to conserve water. Division 3, Section 82 of the City’s Municipal Code “Water Conservation Plan”, which was amended through the adoption of Ordinance No. 1997dopted in April 2022 (discussed in Section 9.2), includes methods for current and ongoing reduction in water use and water waste As identified in Section 5.5, the City’s actual water use rate during CY 2020 was 114 gallons per capita per day which is a decrease of up to 81 gallons per capita per day from the recent historical water use and includes passive savings. The City’s projected water demands, incorporate water use targets less than its established SB X7-7 water use target for 2020 and incorporate ongoing water passive savings and reduced water use. As indicated in Table 4-3, estimated future water savings have been considered as part of the City’s water use projections.

4.2.7 CHARACTERISTIC FIVE-YEAR WATER USE
CWC 10635.
(b) Every urban water supplier shall include, as part of its urban water management plan, a drought risk assessment for its water service to its customers as part of information considered in developing the demand management measures and water supply projects and programs to be included in the urban water management plan. The urban water supplier may conduct an interim update or updates to this drought risk assessment within the five-year cycle of its urban water management plan update. The drought risk assessment shall include each of the following:
(3) A comparison of the total water supply sources available to the water supplier with the total projected water use for the drought period.
(4) Considerations of the historical drought hydrology, plausible changes on projected supplies and demands under climate change conditions, anticipated regulatory changes, and other locally applicable criteria.

The City’s projected water demands are provided in five-year increments over the next 25 years (and through CY 2050) in Table 4-2. The City’s projected water demands and water supplies during a normal year, a single dry year, and a five consecutive year drought over the next 25 years (and through CY 2050) are provided in Chapter 7.

The City’s “Drought Risk Assessment” (DRA) for the next five years (from CY 2021 through CY 2025) is discussed in Section 7.3. The DRA includes the City’s projected annual water demands and supplies for each of the next five years and was prepared based on the five driest consecutive years on record. The DRA provides an assessment of the City’s water service reliability during a drought lasting five years. The DRA reflects anticipated water demands and supplies prior to any expected benefits associated with water supply shortage responses included in the City’s Water Shortage Contingency Plan (provided in Chapter 8). In addition to historical drought hydrology, the City considered impacts to water supplies and demands based on climate change conditions (discussed in Section 4.5) and anticipated regulatory changes, including the urban water use objectives (discussed in Section 4.2.4)

4.2.8 PROGRESS TOWARD MEETING THE WATER LOSS PERFORMANCE STANDARD Pursuant to Water Code Section 10631(d)(3)(C), Retail Suppliers are required to provide data demonstrating whether the Retail Supplier met its State Water Board Water Loss Performance

14.B.

4-13
Standard in 23 CCR Section 980 et seq. for each applicable PWS. Submittal Table 4-6 R allows for reporting on progress toward meeting the Water Loss Performance Standard.

The Water Loss Performance Standard does not have to be met until 2028. However, Water Code Section 10631(d)(3)(C) still requires that Retail Suppliers include data in their 2025 UWMPs to show whether they met it.

The City’s most recent AWWA Water Loss Audit was completed for Audit Year 2025, representing Fiscal Year 2024–2025 (July 1, 2024 through June 30, 2025). The audit results were used to evaluate the City’s progress toward meeting the State Water Resources Control Board’s 2028 Water Loss Performance Standards as shown in Table 4-6.

The City is actively implementing measures to improve water loss performance, with a focus on enhancing data accuracy and system reliability. These efforts include the implementation of a new billing software system to replace an outdated platform, which is expected to improve the accuracy of customer consumption data and reduce apparent losses. In addition, the City conducts annual testing and calibration of production meters to ensure accurate measurement of system input volumes.

Collectively, these actions are intended to strengthen data integrity, improve the reliability of water loss reporting, and support ongoing efforts to track and reduce water loss in alignment with State requirements. These improvements position the City to more effectively monitor system performance and make progress toward achieving established water loss performance standards.

4.3 WORKSHEETS AND REPORTING TABLES
The City’s current and projected water demands, including the water demands for each of the City’s water use sectors, are provided in five-year increments over the next 25 years (and through CY 2050) in Tables 4-1 and 4-2.

4.3.1 OPTIONAL PLANNING TOOL USE ANALYSIS WORKSHEET
As discussed in Section 4.2.5, DWR has deemed the “Planning Tool Worksheet” as optional and the City is not required by DWR to use the tool. The City has provided sufficient water supplies to its customers, including during long-term droughts and years with historically high water demands. The City has also been able to provide water service to meet maximum day water demands for these years, including during the summer months. A further discussion regarding the reliability of the City’s water supply sources is provided in Chapter 7.

4.3.2 DWR 2025 UWMP SUBMITTAL TABLES
The City’s current water demands for each of the water use sectors during CY 2025 are provided in Table 4-1. The City’s projected water demands for each of the water use sectors, in five-year increments over the next 25 years (and through CY 2050), are provided in Table 4-2. Table 4-5 presents the submittal status of the water loss audits for the past five years, including a link to the City’s submitted reports in the Notes section. The City’s annual AWWA water loss audits are provided in Appendix E.

4.4 WATER USE FOR LOWER INCOME HOUSEHOLDS
CWC 10631.1.
(a) The water use projections required by Section 10631 shall include projected water use for single-family and multifamily residential housing needed for lower income households, as defined in Section 50079.5 of the Health and Safety Code, as identified in the housing element of any city, county, or city and county in the service area of the supplier.

14.B.

4-15
California Health and Safety Code 50079.5.
(a) "Lower income households" means persons and families whose income does not exceed the qualifying limits for lower income families… In the event the federal standards are discontinued, the department shall, by regulation, establish income limits for lower income households for all geographic areas of the state at 80 percent of area median income, adjusted for family size and revised annually.

The City’s water demands projections provided in Table 4-2 include projected water demands for lower income single-family and multi-family households. A lower income household is defined as a household with an income less than 80 percent of the area median income, adjusted for family size. For the purpose of this evaluation, the entire Riverside County was used for the “area median income”. The total number of lower income households within the City’s service area was estimated based on billing records provided by the City, a review of the City’s General Plan 2030, a review of median household income range statistics provided by the US Census Bureau (https://data.census.gov/cedsci/), and a review of GIS maps of Disadvantaged Communities2(DACs), including block groups, tracts, and places, provided by DWR. The estimated number of lower income households located within the City’s service area is approximately 67 percent of the total number of households. As indicated in Table 4-2, the total projected residential (single family and multi-family) water demands within the City in 2050 is estimated at about 2,488 AFY. Based on a 67 percent use factor of total residential water demands, the projected water demand for lower income households will be about 2,000 AFY by the CY 2045. The projected water demands for lower income households were included in the City’s total projected water demands, as indicated in Table 4-5.

4.5 CLIMATE CHANGE CONSIDERATIONS
CWC 10630.

It is the intention of the Legislature, in enacting this part, to permit levels of water management planning commensurate with the numbers of customers served and the volume of water supplied, while accounting for impacts from climate change.

CWC 10635.
(b) Every urban water supplier shall include, as part of its urban water management plan, a drought risk assessment for its water service to its customers as part of information considered in developing the demand management measures and water supply projects and programs to be included in the urban water management plan. The urban water

14.B.

4-16
supplier may conduct an interim update or updates to this drought risk assessment within the five-year cycle of its urban water management plan update. The drought risk assessment shall include each of the following…
(4) Considerations of the historical drought hydrology, plausible changes on projected supplies and demands under climate change conditions, anticipated regulatory changes, and other locally applicable criteria.

Climate is defined as “the average course or condition of the weather at a place usually over a period of years as exhibited by temperature, wind velocity and precipitation3”. A change in the climate which produces a greater amount of precipitation (i.e. more runoff and/or snowpack) and lower temperatures is generally a benefit to water supplies. However, drought conditions which may result in decreased precipitation, decreased runoff, and increased temperature may adversely affect an urban water supplier’s ability to meet demands by potentially impacting supplies. Consequently, the focus of impacts of climate change is on these adverse consequences.

Section 6.2 of this Plan describes the City’s sources of water supply, management practices associated with those sources, and the long-term reliability of those sources. Section 7.3 includes a Drought Risk Assessment which considers the potential impacts of climate change to the City’s water supply sources. Chapter 8 provides a detailed discussion of the City’s Water Shortage Contingency Plan, including but not limited to, the six standard water shortage levels in the event climate change results in a reduction to water supplies associated with a periodic drought condition. The following is a discussion of the City’s sources of supply, how those sources may be impacted by climate change, and the proactive actions the City and other local/regional water managers may take to address the potential climate change impacts on water supplies.

Imported Water Supplies
The City has the ability to receive treated imported water as discussed in Section 6.2.1 and relies on the Hemet-San Jacinto Watermaster to manage the groundwater supplies of the San Jacinto Basin. Consequently, the City directly and/or indirectly relies on the Metropolitan Water District of Southern California for those imported water supplies. MWD has prepared a Regional 2025 Urban Water Management Plan which includes a discussion (Section 2 in MWD’s 2025 UWMP) of the reliability of its water supplies and the impacts of climate change and is incorporated by reference in this Plan. Furthermore, the City is located within Eastern Municipal Water District’s water service area which has also provided a discussion of climate change considerations and that discussion is included by reference. The following is a brief summary of MWD’s efforts:

14.B.

4-17
Resource Planning
• MWD has established the Robust Decision Making (RDM) approach to identify vulnerabilities to its water supplies. Climate change information was applied to
• MWD’s simulated water supply scenarios to demonstrate the vulnerability of water supplies to climate change.
• MWD altered the inflow hydrology scenarios on the Colorado River simulation model to reflect modified inflow to MWD’s Colorado River aqueduct.

Knowledge Sharing and Research Support
• MWD is an active and founding member of the Water Utility Climate Alliance (WUCA) which includes 12 nationwide partners collaborating on climate change considerations. As such, MWD shares agency actions on climate change and adaptation. WUCA has also released numerous research papers on climate change.

Implementation of Programs and Policies
• MWD’s programs include the use of solar energy, use of ride share programs, and reduction of greenhouse emissions. Collectively these actions are intended to impact the effects of climate change.

Groundwater Supplies – San Jacinto Basin
The City relies on groundwater produced from the San Jacinto Basin as discussed in Section 6.2.2.

The San Jacinto Basin has been identified by DWR as a very low-priority groundwater basin partially due to the fact it is adjudicated. In that regard, the San Jacinto Basin is actively managed by the Hemet-San Jacinto Watermaster, and those management activities are described in detail in Section 6.2.2.

Recognizing the potential impacts of climate change on the San Jacinto Basin groundwater supplies (decreased local runoff and replenishment, along with increased groundwater production, may lead to decreased groundwater levels), the City has used climate tools available on the California Energy Commission’s Cal-Adapt website (https://caladapt.org/) to identify potential future climate change cycles for the San Jacinto Basin. The CalAdapt website has been developed by the Geospatial Innovation Facility at the University of California, Berkeley with funding and advisory oversight by the California Energy Commission and California Strategic Growth Council.

To address the uncertainty in future greenhouse gas emissions, Cal-Adapt has developed a Representative Concentration Pathway 4.5 (RCP 4.5) scenario and a Representative Concentration Pathway 8.5 (RCP 8.5) scenario. RCP 4.5 represents a scenario in which greenhouse gas emissions peak around 2040, then decline and stabilize. RCP 8.5 represents a

14.B.

4-18
scenario in which emissions continue to strongly rise through 2050 and plateau around 2100. RCP 4.5 is a “medium” emissions scenario that models a future in which there is an effort made by societies to reduce greenhouse gas emissions, whereas RCP 8.5 is a “business-as-usual” scenario. For the City’s climate change analysis, the RCP 4.5 scenario was selected.

The climate tools available on the Cal-Adapt website were used to simulate projected annual precipitation and annual average maximum temperature in the San Jacinto Basin. An electronic boundary of the San Jacinto Basin was submitted online through the Cal-Adapt website in a “KML” file format (i.e. Google Earth format) and data using several of the available climate tools was generated.

Based on the data generated by the Cal-Adapt simulations (see Appendix F), the average annual rainfall in the San Jacinto Basin is projected to be 12.18 inches over the next 25 years (through 2050), compared to historical average of 12.03 inches (from 1950 through 2024). In addition, the average maximum temperature is projected to be 83.31 degrees Fahrenheit compared to a historical average of 79.54 degrees Fahrenheit. Although there may be more precipitation in the future, it may be more likely to fall as rainfall compared to snowfall. The simulations do not denote the duration or intensity of storms contributing to the annual precipitation. Most if not all precipitation (whether it is rain or snowfall) likely will be captured for use in the San Jacinto Basin area and not adversely impacted by a potentially higher average annual temperature.

Recognizing these potential impacts to local hydrology resulting from climate change and the resultant impacts to the groundwater supplies, the Hemet-San Jacinto Watermaster has taken (and may reinstate as needed) the following proactive actions to anticipate and circumvent the potential impacts of climate change. These actions will enable the City to use rely on the San Jacinto Basin as a reliable source of supply.

Adjusted Production Rights
The City produces groundwater from the San Jacinto Basin within an area referred to as the “Management Area”, which includes: the (1) Canyon; (2) San Jacinto Upper Pressure; (3) Hemet South; and (4) Hemet North portion of the Lakeview/Hemet North zones (the City produces groundwater from the Hemet South and San Jacinto Upper Pressure zones). The San Jacinto Basin Judgment estimates the groundwater safe yield of the Management Area to be approximately 45,000 acre-feet per year. The City of Hemet’s Base Production Rights are currently 4,542 acrefeet per year. The Hemet-San Jacinto Watermaster has the ability to reduce the amount of water rights available to Producers before they must pay an assessment for expensive imported water.

This action provides producers with an economic incentive to reduce demands.

Chapter 5 SB X7-7 Baselines, 2020 Targets, and
2025 Reporting
OVERVIEW - CHAPTER 5
Chapter 5 (SB X7-7 Baselines, 2020 Targets and 2025 Reporting) of the City’s 2025 Plan discusses and provides the following:
• The Water Conservation Act of 2009 (or SB X7-7) required the State of California to achieve a 20 percent reduction in urban water use by the year 2020. • SB X7-7 required urban water suppliers, including the City, to develop a “2020 Water Use Target” to assist the State of California to achieve the 20 percent reduction. The 2020 Water Use Target represents the amount of water each person should use per day (i.e. gallons per capita per day or GPCD) by the year 2020. • The City previously determined its 2020 Water Use Target during the preparation of its 2015 Plan by completing standardized tables (or the SB X7-7 Verification Form) to demonstrate compliance with the Water Conservation Act of 2009. The City’s 2020 Water Use Target is 139 GPCD.
• The population within the City’s service area during Fiscal Year 2019-20 was estimated at 30,443. The City’s population was estimated using the California Department of Water Resources’ online “Population Tool” which incorporates United States Census data in a Geographic Information Systems (or GIS) format to estimate the population within the City’s service area.
• The City’s “gross water” use represents the total volume of water entering its distribution system from its water supply sources. The City’s annual gross water during Calendar Year 2020 was 3,891 AF.
• The City’s per-capita water use is based on the gross water use divided by the population. The City’s per-capita water use during Calendar Year 2020 was 114 GPCD.

The City’s confirmed 2020 Water Use Target is 139 GPCD. • The City has also demonstrated compliance with the 2020 Water Use Target by completing the SB X7-7 2020 Target Progress (provided in Appendix H).

5.1 GUIDANCE FOR WHOLESALE AGENCIES
CWC 10608.12.
(I) “Urban wholesale water supplier,” means a water supplier, either publicly or privately owned, that provides more than 3,000 acre-feet of water annually at wholesale for potable municipal purposes.

The City is not a wholesale agency and is not required by DWR to complete Section 5.1.

5.2 SB X7-7 FORMS AND SUMMARY TABLES
The City previously calculated its “Baseline” water periods and a “2020 Water Use Target” in its 2015 Plan. There were two different Baseline periods identified (consisting of a “10-year Baseline” period and a “5-year Baseline” period). The average water use for each of these two Baseline periods, expressed in GPCD, represents the Baseline water use for each period. A 10- year Baseline period was identified by the City and information regarding the starting year, ending year, and average year water use rate during this period is provided in Figure 5-1.

The City determined its 2020 Water Use Target by calculating 80 percent of the 10-year Baseline water use.

According to Section 10608.22 of the California Water Code, if an urban retail water supplier’s 5- year Baseline period water use is greater than 100 GPCD, the calculated 2020 Water Use Target may need to be reduced. A 5-year Baseline period was identified by the City and information regarding the starting year, ending year, and average water use rate during this period is provided in Figure 5-1. The average water use rate during the identified 5-year Baseline period was greater than 100 GPCD. As a result, the 5-year Baseline period was used to determine if the 2020 Water Use Target required any adjustments.

The City’s calculated 2020 Water Use Target was compared with the 95 percent of the average water use within the 5-year Baseline to determine if any adjustments were required. The Baseline water use was used to confirm the City’s 2020 Water Use Target (which represents the per capita water use target for 2020 pursuant to SB X7-7). The baseline daily per capita water use was not updated in the 2020 UWMP nor in this 2025 UWMP per DWR Guidelines.

14.B.

5-21

5.2.1 SB X7-7 VERIFICATION FORM (BASELINES AND TARGETS) The City’s service area has not changed (i.e., expansion or contraction) since the 2015 Plan was prepared. The City’s 2025 Plan incorporates the Baseline water uses, and 2020 Water Use Target calculated in the 2015 Plan. The City previously prepared standardized tables (SB X7-7 Verification Form) to demonstrate compliance with the Water Conservation Act of 2009 in its 2015 Plan, including compliance with the City’s 2015 Interim Water Use Target.

5.2.2 SB X7-7 2020 TARGET COMPLIANCE
SB X7-7 requires urban water suppliers to determine per capita water use targets for comparison against actual per capita water use to demonstrate compliance. In 2005, DWR developed four different technical methods to determine the 2020 per capita water use target:
• Method 1: Estimate per capita water use targets by calculating 80 percent of the urban retail water supplier's baseline, using a 10- to 15-year average. • Method 2: Determine per capita daily water using a sum of defined performance standards. This method requires the sum of water use in indoor residential and landscaped areas, as well as a 10 percent reduction in CII water use. • Method 3: Calculate 95 percent of the applicable hydrologic regional target as presented in the DWR Guidebook (DWR, 2009).
• Method 4: Estimate water savings obtained through identified practices and subtract them from the baseline annual daily per capita water use. Agencies that use this method must use the prescribed procedures identified by DWR and utilize the Method 4 Calculator.

The City selected Method 1 in the 2015 UWMP to establish its 2020 per capita water use target.

Under Method 1, the 2020 target is 80 percent of the 2004 average, which is 139 gpcd.

Characterization
OVERVIEW – CHAPTER 6
Chapter 6 (Water Supply Characterization) of the City’s 2025 Plan discusses and provides the following:
• The City’s water supply sources include groundwater pumped from the San Jacinto Basin and treated, imported water purchased from Metropolitan Water District of Southern California through Eastern Municipal Water District.
• The City’s main source of water supply is groundwater pumped from the San Jacinto Basin.
• A tabulation of the City’s historical water supplies is provided in Section 6.1. • A discussion regarding the City’s imported/wheeled water supplies from Eastern Municipal Water District is provided. Information regarding imported water connections, capacities, reliability, and historical production is provided. • A discussion regarding the City’s groundwater supplies from the San Jacinto Basin is provided. Information regarding basin location, adjudication, management, water levels, water quality, water rights, and historical production is provided. • The City’s proposed future projects to maximum its water supply resources are discussed. • The City’s “energy intensity” is discussed and represents the quantity of energy consumed, measured in kilowatt hours, divided by the volume of water, measured in acre-feet over a one-year period. The total energy intensity associated with the City’s water management processes was estimated during CY 2025.

In this Chapter, the City will identify and describe each of its sources of water supply. In addition, the City will describe the following:
• Management of each water supply source;
• Current provisions of a basin adjudication or Groundwater Sustainability Plan (GSP), as applicable, pertaining to management of groundwater supplies; • Measures the City is taking to develop potential new sources of water supply (as applicable); and
• Opportunities for exchanges and transfers on a long- or short-term basis.

14.B.

6-25
The characterization of the City’s water supply sources will account for the anticipated availability during a normal year, a single dry year, a five consecutive year drought, along with projections through CY 2050.

6.1 WATER SUPPLY ANALYSIS OVERVIEW
CWC 10631.
(b) Identify and quantify, to the extent practicable, the existing and planned sources of water available to the supplier over the same five-year increments described in subdivision (a), providing supporting and related information, including all of the following:
(1) A detailed discussion of anticipated supply availability under a normal water year, single dry year, and droughts lasting at least five years, as well as more frequent and severe periods of drought, as described in the drought risk assessment. For each source of water supply, consider any information pertinent to the reliability analysis conducted pursuant to Section 10635, including changes in supply due to climate change. (2) When multiple sources of water supply are identified, a description of the management of each supply in correlation with the other identified supplies CWC 10631.
(h) An urban water supplier that relies upon a wholesale agency for a source of water shall provide the wholesale agency with water use projections from that agency for that source of water in five-year increments to 20 years or as far as data is available.

6.1.1 SPECIFIC ANALYSIS APPLICABLE TO ALL WATER SUPPLY SOURCES The section below provides a discussion of the following information to the extent practical:
• The City’s existing and planned sources of water supply are identified; • Each source of supply is quantified in five-year increments through CY 2050; • The anticipated supply availability under normal, single dry, and five consecutive dry years, and any other water year conditions included in the Drought Risk Assessment (see Chapter 7) are described;
• The management of each water supply in correlation with other identified supplies is described.
• Information pertinent to the reliability analysis, including climate change effects, is considered.

The City historically has relied on groundwater pumped from the San Jacinto Basin and treated, imported water purchased from Metropolitan Water District of Southern California through Eastern Municipal Water District. The following descriptions summarize the City’s sources of supply (detailed descriptions are provided in Section 6.2).

14.B.

6-27
Existing and Planned Sources of Supply
Purchased Treated Imported Water
The City has the ability to purchase treated imported water and treated city owned wheeled water from Eastern Municipal Water District, as described in Section 6.2.1. In addition, Section 6.2.1 provides a detailed discussion of the existing and planned supply of the treated imported water, including a description of the management and reliability of those treated imported water supplies.

Table 6-8 summarizes the actual treated imported and/or wheeled water supply for CY 2025. In addition, Table 6-9 summarizes the projected water supply, in five-year increments, through CY 2050 under varying water supply conditions.

Groundwater
The City has historically pumped groundwater from the San Jacinto Basin as described in Section 6.2.2. In addition, Section 6.2.2 provides a detailed discussion of the existing and planned supply of the groundwater, including a description of the management and reliability of those groundwater supplies. Table 6-8 summarizes the actual groundwater supplies for CY 2025. In addition, Table 6-9 summarizes the projected water supply, in five-year increments, through CY 2050 under varying water supply conditions.

Surface Water
The City does not directly use surface water to meet its water demands.

Storm Water
The City does not directly use stormwater to meet its water demands.

Wastewater and Recycled Water
The City does not use recycled water sources to meet its water demands.

6.1.2 OTHER CHARACTERIZATION CONSIDERATIONS
A description of the City’s water system along with a map of its service area is included in Chapter

3. In addition, the agencies which manage the water supplies used by the City are identified in Section 6.2.1 (imported water), 6.2.2 (groundwater), 6.2.3 (surface water), 6.2.4 (stormwater), and 6.2.5 (recycled water).

14.B.

6-28

6.1.3 OPTIONAL PLANNING TOOL
As discussed in Section 4.2.5, DWR has created an optional “Planning Tool Worksheet” for water suppliers to review and assess monthly water use trends. DWR has deemed the tool as optional and the City is not required by DWR to use the tool. Section 6.1 provides a tabulation of the City’s historical annual water uses for each water supply source. During the past 15 years, the City experienced a five consecutive year drought within its service area from CY 2011 to CY 2015.

Historical records indicate the City’s annual water demands had been greater prior to CY 2011.

The City has been able to provide sufficient water supplies to its customers, including during longterm droughts and years with historically high water demands. In addition, the City has been able to provide water service to meet maximum day water demands for these years, including during the summer months. A further discussion regarding the reliability of the City’s water supply sources is provided in Chapter 7.

6.2 NARRATIVE SECTIONS FOR SUPPLIER’S UWMP WATER SUPPLY

CHARACTERIZATION

6.2.1 PURCHASED OR IMPORTED WATER
Eastern Municipal Water District (EMWD)
The City of Hemet maintains interconnections with Eastern Municipal Water District (EMWD) to support water supply delivery, operational flexibility, and system reliability. Through these connections, the City has access to both treated imported water and the ability to convey Cityowned groundwater supplies via EMWD’s regional system.

Imported Water Supplies
The City may purchase treated, imported water from EMWD, which is a member agency of the Metropolitan Water District of Southern California (MWD). MWD imports water from the Colorado River via the Colorado River Aqueduct and from Northern California through the State Water Project. These supplies are treated and delivered through EMWD’s system to its member agencies. While the City has the potential to enter into water purchase agreements if needed, current projections indicate that purchased water from this source is not anticipated to be required during the five-year planning period.

EMWD utilizes a tiered rate structure for water sales, which may include higher rates for water delivered above established allocation thresholds.

14.B.

6-29
The City maintains three primary interconnections with EMWD for delivery of treated imported water: Fruitvale (700 gallons per minute [gpm]), Palm (600 gpm), and Bottletree (600 gpm). In addition, the City has two emergency interconnections at Seven Hills (900 gpm) and Searl Park (800 gpm), which may be used during system outages or supply interruptions.

The City does not currently rely on treated imported water from EMWD as a primary source of supply. However, these connections remain available to supplement local supplies during periods of increased demand, supply disruption, or emergency conditions.

Wheeled Groundwater Supplies
In addition to the potential availability of imported water, the City utilizes EMWD’s system to convey City-owned groundwater supplies from the San Jacinto Basin to its distribution system.

This practice, commonly referred to as “wheeling,” allows the City to deliver its own groundwater through EMWD’s regional infrastructure.

Over the past five years, the City has utilized wheeled groundwater supplies ranging from approximately 1,190 acre-feet per year (AFY) to 2,193 AFY, with an average of approximately 1,500 AFY. These supplies represent locally controlled water resources and are not considered purchased or imported water.

The City’s total groundwater supply, including both pumped and wheeled groundwater, is governed by its base production right of 4,542 AFY in the Hemet/San Jacinto Basin, as reflected in Table 6-9. The use of wheeled groundwater provides operational flexibility and supports efficient distribution of available groundwater resources within the City’s system.

Supply Reliability Considerations
Imported water supplies from MWD, conveyed through EMWD, may be subject to reductions during periods of drought or other conditions that limit statewide water availability. In response, MWD has developed a Water Supply Allocation Plan (WSAP), which establishes a framework for allocating available supplies among member agencies during shortage conditions.

Because the City’s primary water supply is locally sourced groundwater, including wheeled supplies, it is less directly impacted by MWD allocation reductions. However, the availability of imported water remains an important supplemental resource that enhances overall system reliability during emergencies or unforeseen supply constraints.

Projected water supplies, including the City’s groundwater production capacity, are presented in Table 6-9.

14.B.

6-30
The City’s access to treated imported water from the Metropolitan Water District of Southern California (MWD), conveyed through Eastern Municipal Water District (EMWD), may be affected during periods of drought or other conditions that limit MWD’s ability to deliver water to its member agencies. While the City does not rely on imported water as a primary supply source, these supplies remain available to supplement local groundwater resources and enhance system reliability during periods of increased demand or emergency conditions.

In anticipation of potential supply reductions, MWD developed a Water Supply Allocation Plan (WSAP), which establishes a framework for equitably allocating available imported water supplies among its member agencies during shortage conditions. The WSAP includes up to ten shortage levels, representing reductions of up to 50 percent.

The WSAP was initially implemented in response to critically dry conditions in 2007, compounded by regulatory restrictions on State Water Project deliveries related to environmental protections in the Sacramento-San Joaquin Delta. MWD formally adopted the WSAP in 2008 and subsequently updated the plan in 2014.

Under the WSAP, MWD establishes allocation levels for each member agency based on historical water use, local supply availability, and conservation performance. Allocations are calculated separately for municipal and industrial demands and replenishment needs. The methodology considers factors such as historical imported water deliveries, local water production, and demand reduction efforts.

In general, the WSAP process calculates total historical member agency demand. That historical demand is then compared to member agency projected local supply for a specific Allocation year.

The balance required from MWD, less an Allocation reduction factor, is the member agency’s “Water Supply Allocation” of imported water from MWD. When a member agency reduces its local demand through conservation or other means, the Allocation of imported water will increase. Depending on MWD’s available supply, MWD can establish a specific WSAP shortage level. The shortage level causes a regional reduction and calculates an allocation for each of its member agency. Additional information about MWD’s WSAP is provided in MWD’s Regional 2020 UWMP which is incorporated by reference. The following is a summary of MWD’s water shortage levels:

Level 1 – Regional Percent Reduction of 5%
Level 2 – Regional Percent Reduction of 10%
Level 3 – Regional Percent Reduction of 15%
Level 4 – Regional Percent Reduction of 20%

Level 7 – Regional Percent Reduction of 35%
Level 8 – Regional Percent Reduction of 40%
Level 9 – Regional Percent Reduction of 45%
Level 10 – Regional Percent Reduction of 50%
Although the City of Hemet’s primary water supply consists of locally sourced groundwater, the WSAP remains relevant as it may affect the availability of supplemental imported water during regional shortage conditions. Additional information regarding the WSAP is provided in MWD’s 2020 Urban Water Management Plan, which is incorporated herein by reference.

SAN JACINTO BASIN
San Jacinto Basin - Sustainable Groundwater Management Act The San Jacinto Basin is identified as Basin Number 8-005 pursuant to DWR Bulletin 118.

Pursuant to the Sustainable Groundwater Management Act of 2014 (SGMA), the San Jacinto Basin was designated a high-priority basin in DWR’s 2019 SGMA Basin Prioritization report. In compliance with SGMA, the Hemet-San Jacinto Watermaster submits its Annual Report to DWR and will need to develop a GSP. SGMA requires the San Jacinto Basin be managed by a Groundwater Sustainability Agency (GSA) by 2022, and that a GSP be implemented by 2024. EMWD’s Board of Directors became the exclusive GSA for the western portion of the San Jacinto Basin (West San Jacinto GSA) on April 24, 2017.

San Jacinto Basin - Adjudication
Local water purveyors in the San Jacinto Basin developed a Groundwater Management Plan (GWMP) in November 2007 for the San Jacinto-Hemet Valley to effectively manage the groundwater basin, allocate and protect groundwater resources, and maintain local control over those resources, as shown in Appendix I. In April 2013, a Stipulated Judgment (Judgment), Case Number RIC 1207274, was entered with the Superior Court of the State of California for the County of Riverside adopting the GWMP and creating the Hemet-San Jacinto Watermaster, as shown in Appendix J.

The Judgment declares individual water rights of EMWD, LHMWD, the Cities of Hemet and San Jacinto, and other private groundwater pumpers to groundwater in (1) the Canyon Sub-basin; (2) the San Jacinto Upper Pressure Sub-basin downstream to Bridge Street; and (3) the Hemet Sub-basin. These sub-basins are collectively referred to as the

14.B.

6-33
Management Area and are located in the San Jacinto Valley. The location of the Management Area is provided in the figure below. The Management Area also includes the (1) Canyon; (2) San Jacinto Upper Pressure; (3) Hemet South; and (4) Hemet North portions of the Lakeview/Hemet North zones. The Hemet-San Jacinto Watermaster Board serves as the governing body for the Management Area and is comprised of elected officials representing the Cities of Hemet and San Jacinto, LHMWD, EMWD, and a representative for private groundwater producers. EMWD and the City of Hemet possess permitted and pre-1914 surface water rights to store, divert, and recharge surface water from the San Jacinto River and its tributaries. In accordance with the Judgment, EMWD, Lake Hemet, and the Cities of Hemet and San Jacinto are required to import a total of 7,500 acre-feet of water annually for basin recharge, of which the City of Hemet is responsible for 1,470 acre-feet. The Judgment also recognizes the Tribal Water Rights of the Soboba Band of Luiseño Indians, determined through a separate settlement among the Soboba Tribe, the United States, EMWD, LHMWD, and MWD. The City’s Base Production Rights are currently 4,542 AFY. The Judgment estimates the groundwater safe yield of the Management Area to be approximately 45,000 AFY and the long-term basin overdraft to be approximately 10,000 AFY.

The powers and duties of the Hemet-San Jacinto Watermaster includes making rules and regulations necessary for its own operations as well as for the operation of the GWMP and the Judgment; the implementation of the Physical Solution; development and implementation of a Water Management Plan; planning and constructing facilities to accomplish the goals of the Judgment; purchase of water for recharge; data collection; levying, billing and collection of all assessments provided for under the Judgment; record keeping; and reporting to the Court.

2. Groundwater Replenishment Program - The Watermaster will administer the Groundwater Replenishment Program. “The program shall include: the acquisition of Supplemental Water; the collection and expenditure of Replenishment Assessments; the Recharge of the Management Area; and the construction and operation of all necessary facilities, including but not limited to, development of surface and subsurface percolation and injection facilities.”

3. Storage Rights - Unused storage capacity will be managed by the Watermaster conjunctively with natural and available Supplemental Water supplies.

4. Recycled Water - “The use of Recycled Water produced by Eastern can be of substantial benefit in providing additional water in the Management Area…Such Recycled Water may be used for Recharge or direct use within the Management Area.”

5. Export - “The Public Agencies may export water outside the Management Area, on a temporary basis, upon approval by the Watermaster. However, any water exported shall be replenished with an appropriate amount of similar or better quality water…” San Jacinto Basin - Description
The City’s water system is primarily reliant on wells which pump from the San Jacinto Basin. The general boundaries of the San Jacinto Basin are the Casa Loma Fault on the southwest, which separates it from the Hemet and Lakeview groundwater basins; the San Jacinto Fault on the northeast, along the base of the San Jacinto Mountains; Valle Vista in the southeast and Moreno in the northwest. The San Jacinto Basin is a structural trough located between two faults that have been filled with layered alluvial materials, including clay, silt, sand and gravel. The City’s wells overlie the San Jacinto Upper Pressure zone and the Hemet South zone of the San Jacinto Basin Management Area. The “Pressure Area” region of the San Jacinto Basin is generally divided into an upper, unconfined aquifer (i.e. the Upper Pressure zone) and a lower, confined aquifer.

The groundwater in the lower aquifer is typically under pressure due to the presence of a relatively impervious, confining layer which provides some separation between the upper and lower aquifers.

The San Jacinto Basin contains sediments that have filled valleys and underlying canyons incised into crystalline basement rock. The valley fill deposits are generally divided into younger and older alluvium. Maximum depths of valley fill reach about 900 feet in the western and northern parts of the San Jacinto Basin but may exceed 5,000 feet in the eastern part of the San Jacinto Basin between the Casa Loma and Claremont faults. Confined groundwater is found in the eastern part of the San Jacinto Basin between the Casa Loma and Claremont fault.

The younger alluvium in the southeastern part of the San Jacinto Basin is generally coarse and permeable with specific yield estimated to range from about 12 to 15 percent. In other parts of

14.B.

6-36
the San Jacinto Basin, specific yield is estimated to be about 5 to 10 percent. The older alluvium may correlate to sediments of Pleistocene age that are exposed in the San Timoteo Badlands and underlies the San Jacinto River near the confluence of Bautista Creek. These sediments generally contain more fine material and have lower specific yield and transmissivity values than the younger alluvium.

The San Jacinto fault zone cuts through the eastern part of the San Jacinto Basin and is composed of five northwest trending sediments: the San Jacinto, Claremont, Hot Springs, Park Hill, and Casa Loma faults. These active faults are barriers to groundwater movement. Natural recharge to the San Jacinto Basin is primarily from percolation of flow in the San Jacinto River and its tributary stream and from infiltration of rainfall on the valley floor. The primary recharge area for the confined aquifers is found where the San Jacinto River and Bautista Creek enter the San Jacinto Valley. Percolation of water stored in Lake Perris has been an additional source of recharge since construction of the lake in the 1970s.

Prior to the extraction of groundwater from the San Jacinto Basin, groundwater flow was generally along the course of the San Jacinto River and westward out of the San Jacinto Basin.

High extraction rates had produced groundwater depressions and locally reversed the historical flow pattern. During the 1960s, groundwater levels in the western and central parts of the San Jacinto Basin declined; whereas, in the south-central part of the San Jacinto Basin, they were moderately stable. During the 1970s through the 1990s, groundwater levels declined about 20 to 40 feet in the northern and southwestern parts of the San Jacinto Basin and were relatively stable in the southern part of the San Jacinto Basin. During the 1970s through the 1980s, groundwater levels rose 80 to 200 feet in the western part of the San Jacinto Basin because of infiltration from Lake Perris.

Groundwater levels within the San Jacinto Basin have remained relatively stable in the Lakeview, San Jacinto Lower Pressure, Menifee, and Hemet South Management Zones. In the Perris North and South Management Zones, groundwater levels have generally risen within the past five years. Pursuant to DWR Bulletin 118, the total groundwater storage capacity of the San Jacinto Basin is estimated to be about 3,070,000 acre-feet. In 1975, the calculated amount of groundwater in storage was 2,700,000 acre-feet.

Pursuant to the “Hemet/San Jacinto Groundwater Management Area, 2019 Annual Report “, the best quality groundwater generally occurs along the San Jacinto River in the Canyon and San Jacinto Upper Pressure groundwater management zones, where there is significant municipal extraction. Additional information regarding the basin-wide water quality sampling program, including for Total Dissolved Solids (TDS) and Nitrate as Nitrogen, is provided in the San Jacinto Basin annual reports4.

San Jacinto Basin - Historical and Projected Basin Production The City currently produces groundwater from the San Jacinto Basin. As discussed above, the City’s Base Production Rights to the San Jacinto Basin are 4,542 AFY. The City’s production from the San Jacinto Basin over the past five years has been tabulated in Table 6-1 and ranges from 1,821 AFY to 2,724 AFY, with an average of 2,370 AFY.

The City’s projected production from the San Jacinto Basin, over the next 25 years in five-year increments, is provided in Table 6-9.

6.2.5.1 RECYCLED WATER COORDINATION
CWC 10633.

The plan shall provide, to the extent available, information on recycled water and its potential for use as a water source in the service area of the urban water supplier. The preparation of the plan shall be coordinated with local water, wastewater, groundwater, and planning agencies that operate within the supplier’s service area…
The City does not have access to recycled water supplies due to the lack of infrastructure to convey recycled water to the City. Subject to availability of recycled water, the City would have to construct transmission and distribution facilities to deliver recycled water to customers within its service area. Additional information regarding the potential use of recycled water is provided below.

6.2.5.2 WASTEWATER COLLECTION, TREATMENT, AND DISPOSAL
CWC 10633.
(a) A description of the wastewater collection and treatment systems in the supplier’s service area, including a quantification of the amount of wastewater collected and treated and the methods of wastewater disposal.

The City does not own or operate any wastewater treatment facilities. All sewage generated within the City water system is provided to the San Jacinto Valley Regional Water Reclamation Facility (RWRF), which is operated by EMWD and is located outside the City’s service area. In 2011, EMWD began a $157 million expansion project for RWRF. Work on the RWRF was completed in early 2015. RWRF’s maximum capacity increased from 7.5 million gallons per day (MGD) to 14 MGD. Based on the City’s “Water and Sewer Master Plan Update”, dated March 2021, the wastewater generation rate within the City’s service area is approximately 42 GPCD.

Based on a CY 2025 population of 33,591, it is estimated the total wastewater generated, collected, and treated within the City’s service area during CY 2025 was approximately 1,591 AF, as shown in Table 6-2.

Treated wastewater is not disposed of within the City’s service area, as shown in Table 6-3.

6.2.5.3 RECYCLED WATER SYSTEM DESCRIPTION
CWC 10633.
(c) A description of the recycled water currently being used in the supplier’s service area, including, but not limited to, the type, place, and quantity of use.

The City does not have access to recycled water due to the lack of infrastructure to convey recycled water supplies to the City. Subject to the availability of recycled water, the City would need to construct transmission and distribution facilities to deliver recycled water to customers within its service area.

6.2.5.4 POTENTIAL, CURRENT, AND PROJECTED RECYCLED WATER USES CWC 10633.
(b) A description of the recycled water currently being used in the supplier’s service area, including, but not limited to, the type, place, and quantity of use. A description of the quantity of treated wastewater that meets recycled water standards, is being discharged, and is otherwise available for use in a recycled water project. (d) A description and quantification of the potential uses of recycled water, including, but not limited to, agricultural irrigation, landscape irrigation, wildlife habitat enhancement, wetlands, industrial reuse, groundwater recharge, indirect potable reuse, and other appropriate uses, and a determination with regard to the technical and economic feasibility of serving those uses.
(e) The projected use of recycled water within the supplier’s service area at the end of 5, 10, 15, and 20 years, and a description of the actual use of recycled water in comparison to uses previously projected pursuant to this subdivision.

Currently, the wastewater collected from the City and treated at RWRF already is used by other recycled water customers that are outside of the City’s service area boundaries. Therefore, Table 6-4 and Table 6-5 are intentionally blank.

6.2.5.5 ACTIONS TO ENCOURAGE AND OPTIMIZE FUTURE RECYCLED WATER USE CWC 10633.

The plan shall provide, to the extent available, information on recycled water and its potential for use as a water source in the service area of the urban water supplier. The preparation of the plan shall be coordinated with local water, wastewater, groundwater, and planning agencies that operate within the supplier’s service area, and shall include all of the following:
(g) A plan for optimizing the use of recycled water in the supplier’s service area, including actions to facilitate the installation of dual distribution systems, to promote recirculating uses, to facilitate the increased use of treated wastewater that meets recycled water standards, and to overcome any obstacles to achieving that increased use.

Recycled water produced by RWRF is fully contracted to its recycled water customers for beneficial, non-potable reuse. Consequently, recycled water is not currently used within the City, and no future projects have been identified with recycled water use estimates. There are currently no actions in place at the time by which the City is able to encourage the use of recycled water to their customers. Therefore, Table 6-6 is left intentionally blank.

6.2.6 DESALINATED WATER OPPORTUNITIES
CWC 10631.
(g) Describe the opportunities for development of desalinated water, including, but not limited to, ocean water, brackish water, and groundwater, as a long-term supply.

San Jacinto Groundwater Basin
The City does not have opportunities to incorporate desalinated water into its supply. Although there is currently no brackish water in the Management Area, portions of the Management Area have average TDS concentrations above the recommended state secondary MCL of 500 mg/L but below the upper state secondary MCL of 1,000 mg/L. In order to improve long-term sustainability, groundwater desalination to reduce TDS may be considered. There may also be opportunities for use of desalinated ocean water as a future potential water supply source, if needed, through coordination with other agencies that have ocean desalination programs.

6.2.7 WATER EXCHANGES AND TRANSFERS
CWC 10631.
(c) Describe the opportunities for exchanges or transfers of water on a short-term or longterm basis.

6.2.7.1 EXCHANGES
Pursuant to DWR’s 2025 Final Guidebook, “Water exchanges are typically water delivered by one water user to another water user, with the receiving water user providing water in return at a specified time or when the conditions of the parties’ agreement are met. Water exchanges can be strictly a return of water on a basis agreed upon by the participants or it can include payment and the return of water.”
The City does not have any current or planned water exchange opportunities.

14.B.

6-45

6.2.7.2 TRANSFERS
Pursuant to DWR’s 2025 Final Guidebook, “The Water Code defines a water transfer as a temporary or long-term change in the point of diversion, place of use, or purpose of use due to a transfer, sale, lease, or exchange of water or water rights.” Pursuant to San Jacinto Judgment, the City’s carry-over credits represent the difference between the City’s adjusted Production Rights (as well as a share of imported water and supplemental water) and the City’s actual production. Carry-over credits can be used to reduce the amount of water for which a Replenishment Assessment must be paid. Carryover credits can also be transferred to the Watermaster or another public agency. Carryover credits may be retained for more than on calendar year. Although not anticipated, if the City’s projected water demands are greater than the City’s Base Production Right, the City may use any carry-over credits to offset any future annual production greater than its adjusted Production Right.

As discussed in Section 6.2.1, the City can purchase treated water from EMWD.

However, EMWD can deliver groundwater to the City (at a reduced “wheeling charge”) using the City’s Production Rights, in lieu of the normal cost. If necessary, the City may potentially purchase water from EMWD at the lower rate through transfer of the City’s Production Rights for that year.

The City may also potentially sell its carry-over right to offset any costs in purchasing water supplies from EMWD at the full rate.

6.2.7.3 EMERGENCY INTERTIES
The City has emergency interties (or interconnections) with another water agency that serve as short-term emergency water supplies. Emergency interconnections are distribution system interconnections between water agencies for use during critical situations where one system or the other is temporarily unable to provide sufficient potable water to meet its water demands and/or fire protection needs. An emergency interconnection will allow a water system to continue serving water during critical situations such as local water supply shortages as a result of earthquakes, fires, prolonged power outages, and droughts.

As discussed previously, the City has three (3) interconnections to purchase treated water from EMWD. The City has an additional two (2) interconnections with EMWD (900 gpm and 800 gpm) for emergency purposes. The City also has one (1) emergency interconnection with Lake Hemet Municipal Water District (with a capacity of 900 gpm). Historically, the City has relied on EMWD for purchased treated imported water to supplement the City’s groundwater supplies in case of an emergency.

14.B.

6.2.8 FUTURE WATER PROJECTS
CWC 10631.
(f) Include a description of all water supply projects and water supply programs that may be undertaken by the urban water supplier to meet the total projected water use, as established pursuant to subdivision (a) of Section 10635. The urban water supplier shall include a detailed description of expected future projects and programs that the urban water supplier may implement to increase the amount of the water supply available to the urban water supplier in normal and single-dry water years and for a period of drought lasting five consecutive water years. The description shall identify specific projects and include a description of the increase in water supply that is expected to be available from each project. The description shall include an estimate with regard to the implementation timeline for each project or program.

The City’s water supply sources include groundwater from the San Jacinto Basin, including both pumped and wheeled groundwater conveyed through Eastern Municipal Water District’s (EMWD) system, as well as access to treated imported water delivered via EMWD. These water supply sources provide sufficient capacity and operational flexibility to meet the City’s current and projected water demands.

The City is currently installing treatment to remove 1,2,3-Trichloropropane contamination from its San Jacinto Basin wells. The City plans to reactivate two wells (Wells 15 and 16) which were previously removed from service due to the 1,2,3-Trichloropropane contamination. The City anticipates the 1,2,3-Trichloropropane treatment facility will be completed by 2027. The City will also construct new groundwater production wells to replace existing wells when necessary.

The City plans to construct one additional groundwater well by 2029 to increase its total well production capacity. The City also plans to construct a new reservoir at its Echo Hills site to meet fluctuations in daily water demands, fire flow demands, and emergency conditions, as well as allow the City to pump water during off-peak power periods.

6.2.9 SUMMARY OF EXISTING AND PLANNED SOURCES OF WATER
CWC 10631.
(b) Identify and quantify, to the extent practicable, the existing and planned sources of water available to the supplier over the same five-year increments described in subdivision (a), providing supporting and related information, including all of the following… (b)(2) When multiple sources of water supply are identified, a description of the management of each supply in correlation with the other identified supplies. (h) An urban water supplier that relies upon a wholesale agency for a source of water shall provide the wholesale agency with water use projections from that agency for that source of water in five-year increments to 20 years or as far as data is available. The wholesale agency shall provide information to the urban water supplier for inclusion in the urban water supplier’s plan that identifies and quantifies, to the extent practicable, the existing and planned sources of water as required by subdivision (b), available from the wholesale agency to the urban water supplier over the same five-year increments, and during various water-year types in accordance with subdivision (f). An urban water supplier may rely

14.B.

6-48
upon water supply information provided by the wholesale agency in fulfilling the plan informational requirements of subdivisions (b) and (f).

6.2.9.1 DESCRIPTION OF SUPPLIES
As discussed in Section 6.2, the City’s water supply sources consist of treated imported water purchased from EMWD (see Section 6.2.1) and groundwater from the San Jacinto Basin (see Section 6.2.2). The actual quantities of the water supply sources available to the City during CY 2025 are summarized in Table 6-8. The reliable quantities of projected water supply sources available to the City in five-year increments through CY 2050 during normal or average years are summarized in Table 6-9. The reliability of these sources of supply are addressed in Section 7.2.3, including during normal years, single dry years, and five consecutive year droughts.

The order of use of the City’s projected reliable water supplies from CY 2025 through CY 2050 in five-year increments is based on historical practices, water supply availability, and the cost of water. It is anticipated the City will initially use groundwater produced from the San Jacinto Basin.

It is important to note the City’s projected demands in CY 2050 are greater than the City’s Base Production Right of 4,542 AFY. To the extent available, the City initially will use any available carry-over credits to offset any future annual production greater than its adjusted Production Right. The balance of the future annual production greater than the City’s adjusted Production Right will be addressed through an assessment for the purchase of water from EMWD for groundwater replenishment. Currently there is no requirement that the Watermaster must deliver the replenishment water in the immediately following year. The City may also purchase treated imported water from EMWD.

6.2.9.2 QUANTIFICATION OF SUPPLIES
The actual quantities of the water supply sources available to the City during CY 2025 are summarized in Table 6-8. The reliable quantities of projected water supply sources available to the City in five-year increments through CY 2050 during average years are summarized in Table 6-9. The reliability of these sources of supply are addressed in Section 7.2.3, including during normal years, single dry years, and five consecutive year droughts.

The City’s projected quantities of groundwater supplies from San Jacinto Basin are based on historical long-term averages and available supplies during previous dry year conditions. The City’s projected quantities of treated imported water supplies are based on meeting the remainder of the City’s total water demands. As noted above, in the event treated imported water may be limited, the City has the flexibility to increase groundwater production from the

14.B.

6-49
San Jacinto Basin. Consequently, it is anticipated the City will have sufficient water supplies available to meet projected demands.

6.2.10 SPECIAL CONDITIONS
The City considered the issues described below when developing its planned sources of water supply.

6.2.10.1 CLIMATE CHANGE EFFECTS
Climate change has the possibility of impacting the availability of planned water supplies, particularly during a drought period. Section 4.5 of this Plan provides a discussion regarding climate change effects on the City’s various sources of supply.

6.2.10.2 REGULATORY CONDITIONS AND PROJECT DEVELOPMENT
The City has considered the implications of changing regulatory conditions and project development on the availability of planned water supplies. Section 1.4 provides a discussion on the reduced reliance on imported water supplies.

6.2.10.3 OTHER LOCALLY APPLICABLE CRITERIA
There are no locally applicable criteria which applies to the City.

6.3 SUBMITTAL TABLES COMPLETION USING THE OPTIONAL PLANNING TOOL
As discussed in Section 4.2.5, DWR has created an option “Planning Tool Worksheet” for water suppliers to review and assess monthly water use trends. DWR has deemed the tool as optional and the City is not required by DWR to use the tool. Section 6.1 provides a tabulation of the City’s historical annual water uses for each water supply source. During the past 15 years, the City experienced a five consecutive year drought within its service area from CY 2011 to CY 2015.

Historical records indicate the City’s annual water demands had been greater prior to CY 2011.

The City has been able to provide sufficient water supplies to its customers, including during five consecutive year droughts and years with historically high water demands. In addition, the City has been able to provide water service to meet maximum day water demands for these years,

14.B.

6-51
including during the summer months. A further discussion regarding the reliability of the City’s water supply sources is provided in Chapter 7.

6.4 ENERGY USE
CWC 10631.2.
(a) In addition to the requirements of Section 10631, an urban water management plan shall include any of the following information that the urban water supplier can readily obtain:
(1) An estimate of the amount of energy used to extract or divert water supplies. (2) An estimate of the amount of energy used to convey water supplies to the water treatment plants or distribution systems.
(3) An estimate of the amount of energy used to treat water supplies. (4) An estimate of the amount of energy used to distribute water supplies through its distribution systems.
(5) An estimate of the amount of energy used for treated water supplies in comparison to the amount used for nontreated water supplies.
(6) An estimate of the amount of energy used to place water into or withdraw from storage.
(7) Any other energy-related information the urban water supplier deems appropriate. “Energy intensity” is defined as the quantity of energy consumed, measured in kilowatt hours (kWh), divided by the volume of water, measured in acre-feet for a water management process over a one-year period. The information used to calculate the estimated energy intensity associated with the City’s water system is provided below. The energy intensity information is based on readily obtainable energy and water use data for the following water management processes: 1) extraction or diversion of water supplies; 2) placement into storage; 3) conveyance to distribution; 4) treatment; and 5) water system distribution.

The City has tabulated its energy intensity using readily obtainable energy consumption data obtained from monthly electricity bills from Southern California Edison (SCE) for the whole water system and the corresponding water use data obtained from available water meter readings. The City has reported the energy intensity associated with the water management processes which occur within its operational control. Because the City does not track individual energy usage for

14.B.

6-52
each water management process identified above, the City has estimated the energy intensity using the a “total utility approach” (i.e. sum of all water management processes). The total energy consumed was approximately 2,702,303 kWh during CY 2025. Although the total energy consumption reported includes electricity usage for general administration (e.g. at the City’s headquarters) which is not associated with any water management processes, the general administration energy usage is considered negligible compared to overall water system use and has not been netted out.

The total volume of water entering the potable water system was approximately3,851AF during CY 2025 and is consistent with the total volume of water provided in Table 4-1.

The total energy intensity associated with the City’s water management processes is estimated at 686 kWh/AF. The energy intensity data and calculations based on the “total utility approach” are provided in Table O-1B below.

The City’s water management processes do not include “consequential hydropower generation” where the energy generation is a direct consequence of water delivery (i.e. all water passing through the energy generation devices is delivered to users). The City’s water management processes do not include “non-consequential hydropower generation” where the energy generation is not a direct consequence of water delivery (i.e. energy could be generated even if no water was being delivered to water users). In addition, the City’s water management processes do not include any substantial “self-generated energy sources” including solar, wind, geothermal, biomass, co-generation, and diesel generator sources.

Chapter 7 Water Service Reliability and
Drought Risk Assessment
OVERVIEW – CHAPTER 7
Chapter 7 (Water Service Reliability and Drought Risk Assessment) of the City’s 2025 Plan discusses and provides the following:
• Calendar Year 2025 represents an “average” or “normal” water year for the City in which the total amount of rainfall was similar to the historical average rainfall. • A “single dry” year for the City was represented in Calendar Year 2017, in which the total amount of rainfall was below the historical average rainfall. • A “five consecutive year drought” period for the City is represented from Calendar Year 2011 to Calendar Year 2015, where the total amount of rainfall during each of these years was less than the historical average rainfall.
• The City’s current and projected water supplies available during normal years in five-year increments over the next 25 years are provided (through Calendar Year 2050) as shown on Table 7-2.
• The City’s current and projected water supplies available during single dry years in fiveyear increments over the next 25 years are provided (through Calendar Year 2050) as shown on Table 7-3.
• The City’s current and projected water supplies available during each year of a five consecutive year drought in five-year increments over the next 25 years are provided (through Calendar Year 2050) as shown on Table 7-4.
• The reliability of the City’s water supply sources, including a review of water supply constraints, is provided. A single dry year or a five consecutive year drought period will not compromise the City’s ability to provide a reliable supply of water to its customers. • A Drought Risk Assessment (or DRA) is provided which includes an assessment of the City’s water supply reliability over a five consecutive year drought period. The City’s DRA assumes a five consecutive year drought from Calendar Year 2026 through Calendar Year 2030 and includes a review of water supplies, water uses, and water supply reliability for each water supply source during this period. The City’s water system has experienced a prior five consecutive year drought with no limitation to its collective water supplies.

However, the cost of those water supplies may have increased based on the mix of water supplies which are used. Consequently, the City has the ability to enact varying water shortage levels (see Chapter 8) to help educate its customers and provide an economic incentive for the retail customers to reduce their water consumption.

7.1 INTRODUCTION
This section of the City’s UWMP describes the City’s ability to meet retail customer water demands by analyzing a variety of factors which affect the City’s water supply. This section assesses the City’s water service reliability during average years, single dry years, and during a five consecutive year drought period to meet the water needs of its customers. This section also includes the discussion of a Drought Risk Assessment (DRA) which provides a mechanism for the City to evaluate the risk to its water supply under a drought lasting for the next five consecutive years.

7.2 WATER SERVICE RELIABILITY ASSESSMENT
CWC 10635.
(a) Every urban water supplier shall include, as part of its urban water management plan, an assessment of the reliability of its water service to its customers during normal, dry, and multiple dry water years. This water supply and demand assessment shall compare the total water supply sources available to the water supplier with the long-term total projected water use over the next 20 years, in five-year increments, for a normal water year, a single dry water year, and a drought lasting five consecutive water years. The water service reliability assessment shall be based upon the information compiled pursuant to Section 10631, including available data from state, regional, or local agency population projections within the service area of the urban water supplier.

Information regarding the reliability of the City’s water supplies is based on the historical precipitation data in the San Jacinto Valley. Historical annual precipitation in the San Jacinto Valley is discussed in Section 3.3 and is based on historical data collected from Station 047813 (San Jacinto Ranger Station, California). Furthermore, Section 4.5 of this Plan notes that potential future climate change impacts may result in an increase in the average annual precipitation within the City’s service area, thus indicating use of historical data is a reasonable and conservative approach. As indicated in Section 3.3, the historical average rainfall in the vicinity of the City’s service area is 11.44 inches. CY 2025 represents an average or normal water year for the City in which the total amount of rainfall was similar to the historical average rainfall. A single dry year for the City was represented in CY 2017, in which the total amount of rainfall was below the historical average rainfall. A five consecutive year drought period for the City is represented from CY 2011 to CY 2015, where the total amount of rainfall during each of these years was less than the historical average rainfall. Table 7-1 summarizes these “base years” for average, single dry, and five consecutive year drought and provides the total amount of water supplies available

14.B.

7-56
to the City during those base years. The following discussion assesses the water service reliability of the City’s water supply sources.

Water Service Reliability - Imported Water
The City’s treated imported water supplies from MWD, through EMWD, may be impacted during a multi-year drought or other conditions which limits MWD from delivering sufficient water supplies to all of its member agencies, and consequently to the City. In anticipation of such a reduction in supplies, MWD developed a WSAP which is briefly described below. The WSAP provides a means of equitably providing reduced water supplies to each of MWD’s member agencies for up to 10 levels of reduction representing up to a 50 percent reduction.

During calendar year 2007, critically dry conditions impacted MWD’s water supply sources. In addition, a ruling in the Federal Courts in August 2007 provided protective measures for the Delta Smelt (and subsequently other aquatic species) in the Sacramento-San Joaquin River Delta resulting in restrictions on the availability of State Water Project water. As a result, MWD adopted a WSAP in February 2008 to allocate available water supplies to its member agencies. MWD revised the WSAP in December 2014.

The WSAP establishes ten different shortage levels and a corresponding Allocation to each member agency. Based on the shortage levels established by MWD, the WSAP provides a separate reduced Allocation to a member agency for its 1) Municipal and Industrial (M&I) retail demand and 2) replenishment demand. The WSAP formula considers historical local water production, full service treated water deliveries, agricultural deliveries and water conservation efforts when calculating each member agency’s Allocation.

In general, the WSAP process calculates total historical member agency demand. That historical demand is then compared to member agency projected local supply for a specific Allocation year.

The balance required from MWD, less an Allocation reduction factor, is the member agency’s “Water Supply Allocation” of imported water from MWD. When a member agency reduces its local demand through conservation or other means, the Allocation of imported water will increase. Depending on MWD’s available supply, MWD can establish a specific WSAP shortage level. The shortage level causes a regional reduction and calculates an allocation for each of its member agency. Additional information about MWD’s WSAP is provided in MWD’s Regional 2025 UWMP which is incorporated by reference. The following is a summary of MWD’s water shortage levels:

Level 1 – Regional Percent Reduction of 5%
Level 2 – Regional Percent Reduction of 10%
Level 3 – Regional Percent Reduction of 15%
Level 4 – Regional Percent Reduction of 20%

14.B.

7-57
Level 5 – Regional Percent Reduction of 25%
Level 6 – Regional Percent Reduction of 30%
Level 7 – Regional Percent Reduction of 35%
Level 8 – Regional Percent Reduction of 40%
Level 9 – Regional Percent Reduction of 45%
Level 10 – Regional Percent Reduction of 50%
In response to a fourth consecutive year of below average rainfall and critically dry conditions, MWD declared a WSAP Allocation Level 3 for fiscal year 2015-16, which represented a regional reduction of 15 percent. MWD rescinded the WSAP for fiscal year 2016-17 and has not reinstated the WSAP since that time.

Water Service Reliability - Groundwater
The San Jacinto Basin groundwater supplies are managed by the Hemet-San Jacinto Watermaster, as discussed in Section 6.2.2. During a normal year (CY 2025), the City met about 69 percent of its total demands with supplies from the San Jacinto Basin. During a single dry year (CY 2017), the City met about 94 percent of its total demands with supplies from the San Jacinto Basin. During a five consecutive year drought (CY 2011 to CY 2015), the City met about 98 to 100 percent of its total demands with supplies from the San Jacinto Basin. As noted previously, groundwater has previously been impacted by contamination, including 1,2,3-Trichloropropane.

However, as discussed in Section 6.2.8, the City is currently developing appropriate treatment to remove 1,2,3-Trichloropropane which will need to be approved by SWRCB-DDW. Pending SWRCBDDW approval of the treatment facilities, these groundwater supplies are considered reliable both from a water quality and quantity standpoint.

Water Service Reliability Summary
Table 7-1 shows the water supplies during the base years (for average year, single dry year and a five consecutive year drought). As a result of the City’s water supply portfolio, water supplies may be re-apportioned during a five consecutive year drought to meet the City’s water demands.

7.2.1 SERVICE RELIABILITY – CONSTRAINTS ON WATER SOURCES CWC 10631.
(b)(1) A detailed discussion of anticipated supply availability under a normal water year, single dry year, and droughts lasting at least five years, as well as more frequent and severe periods of drought, as described in the drought risk assessment. For each source of water supply, consider any information pertinent to the reliability analysis conducted pursuant to Section 10635, including changes in supply due to climate change.

The City’s sources of supplies consist of groundwater pumped from the San Jacinto Basin and treated, imported water purchased from Metropolitan Water District of Southern California through Eastern Municipal Water District, as described in Section 6.2. Although all of these supplies are managed, the following constraints may occur which the City has considered in this reliability analysis.

San Jacinto Basin
The City produces groundwater from the San Jacinto Basin. As noted previously, the groundwater has been impacted by contamination, including 1,2,3-Trichloropropane.

However, as discussed in Section 6.2.8, the City is currently developing appropriate treatment to remove 1,2,3-Trichloropropane which will need to be approved by SWRCBDDW. Pending SWRCB-DDW approval of the treatment facilities, these groundwater supplies are considered reliable both from a water quality and quantity standpoint.

Imported water
The City may also receive treated imported water from the Metropolitan Water District of Southern California (MWD) conveyed through EMWD. Water supply reliability associated with imported supplies is addressed in MWD’s 2025 Regional Urban Water Management Plan.

7.2.2 SERVICE RELIABILITY – YEAR TYPE CHARACTERIZATION

7.2.2.1 TYPES OF YEARS
The City’s base years for an average year, a single dry year, and a five consecutive year drought are discussed in Section 7.2 and are summarized in Table 7-1. As indicated in Chapter 6, the City’s water supplies sources have been sufficient in meeting the City’s historical water demands during an average year, a single dry year, and a five consecutive year drought. An average year was based on a historical year during the past 15 years with a total precipitation similar to the historical average precipitation in the vicinity of the City’s service area. Because a single dry year or a five consecutive year drought period will not compromise the City’s ability to provide a reliable supply of water to its customers, a single dry year in this Plan was selected based one of the driest years during the past 15 years. The five consecutive year drought period was based on a period of five consecutive dry years during the past 15 years.

As indicated in Section 3.3, the historical average rainfall in the vicinity of the City’s service area is 11.44 inches. CY 2025 represents an average or normal water year for the City in which the total amount of rainfall was similar to the historical average rainfall. A single dry year for the City was represented in CY 2017, in which the total amount of rainfall was less than the historical average rainfall. A five consecutive year drought period for the City is represented from CY 2011 to CY 2015, where the total amount of rainfall during each of these years was less than the historical average rainfall. Table 7-1 summarizes these “base years” for an average year, a single dry year and a five consecutive year drought period and provides the total amount of water supplies available to the City during those base years.

7.2.2.2 SOURCES FOR WATER DATA
The monthly historical average temperatures (including minimum and maximum), monthly historical average rainfall, and monthly evapotranspiration in the vicinity of the City’s service area are discussed in Section 3.3 Historical climate information was obtained from the WRCC and from DWR’s CIMIS.

7.2.3 WATER SERVICE RELIABILITY – SUPPLY AND DEMAND COMPARISON CWC 10635.
(a) Every urban water supplier shall include, as part of its urban water management plan, an assessment of the reliability of its water service to its customers during normal, dry, and multiple dry water years. This water supply and demand assessment shall compare the total water supply sources available to the water supplier with the long-term total projected water use over the next 20 years, in five-year increments, for a normal water year, a single dry water year, and a drought lasting five consecutive water years. The

14.B.

7-61
water service reliability assessment shall be based upon the information compiled pursuant to Section 10631, including available data from state, regional, or local agency population projections within the service area of the urban water supplier.

The City primarily obtains its water supplies from groundwater wells located in the San Jacinto Basin. As discussed in Section 7.3 and shown in Table 7-2, Table 7-3, and Table 7-4, each of the City’s water supply sources share the same base years. As previously discussed in Section 7.2.1, a single dry year or a five consecutive year drought period will not compromise the City’s ability to provide a reliable supply of water to its customers.

As previously discussed in Section 4.2.6, the City’s projected normal year water demands over the next 25 years, in five-year increments, were based on the City’s 2020 Water Use Target of 139 GPCD for potable water demands. The ratio of total water supplies (including potable and recycled water supplies) available to the City during a historical average year in CY 2020 (or 3,891 AF) and during a historical single dry year in CY 2017 (or 3,774 AF) was used to estimate the City’s projected water demands during single dry years. The ratio of water supplies available (base production rights in Hemet San Jacinto Basin) to the City during a historical average year in CY 2025 (or 4,542 AF) and a historical five consecutive year drought period from CY 2011 to CY 2015 (or 4,325 AF, 4,495 AF, 4,539 AF, 4,458 AF, and 3,750 AF, respectively) was used to estimate the City’s projected water demands during a five consecutive year drought period. The City’s projected dry year water supplies over the next 25 years were based on the City’s base production rights in the Hemet San Jacinto Basin of 4,542 AC/FTto meet single-dry year demands.

Table 7-2, Table 7-3, and Table 7-4 summarize the City’s projected water demands and supplies over the next 25 years in five-year increments, including during normal years, single dry years, and a five consecutive year drought periods. These tables indicate the City can meet water demands during normal years, single dry years, and a five consecutive year drought periods over the next 25 years.

7.2.3.1 WATER SERVICE RELIABILITY – NORMAL YEAR

7.2.4 DESCRIPTION OF MANAGEMENT TOOLS AND OPTIONS
CWC 10620.
(f) An urban water supplier shall describe in the plan water management tools and options used by that entity that will maximize resources and minimize the need to import water from other regions.

As noted in Section 6.2.2, the San Jacinto Basin is managed by the Hemet-San Jacinto Watermaster. During the period of management under the Judgment, significant drought events have occurred. In each drought cycle the San Jacinto Basin has been managed to maintain water levels. Therefore, based on historical and on-going management practices, the City will be able to rely on the San Jacinto Basin for adequate supply over the next 25 years under single dry years and a five consecutive year drought periods.

Section 6.2.2 provides a description of the management of groundwater resources in the San Jacinto Basin, as well as information on basin management. Chapter 6 also demonstrates the management structure of the San Jacinto Basin provides a reliable source of groundwater supply for the City during a normal year, a single-dry year and a five consecutive year drought. Historical data indicates the San Jacinto Basin has been well managed for the full period of the adjudication, resulting in a stable and reliable water supply. Basin management changes are discussed in Section 6.2.2, and include increased direct use of recycled water (see Section 6.5) to reduce the need to import water from other regions. Therefore, the groundwater supplies in the San Jacinto Basin are deemed reliable.

7.3 DROUGHT RISK ASSESSMENT
CWC 10635.
(b) Every urban water supplier shall include, as part of its urban water management plan, a drought risk assessment for its water service to its customers as part of information considered in developing the demand management measures and water supply projects and programs to be included in the urban water management plan. The urban water supplier may conduct an interim update or updates to this drought risk assessment within the five-year cycle of its urban water management plan update. The drought risk assessment shall include each of the following:
(1) A description of the data, methodology, and basis for one or more supply shortage conditions that are necessary to conduct a drought risk assessment for a drought

14.B.

7-66
period that lasts five consecutive water years, starting from the year following when the assessment is conducted.
(2) A determination of the reliability of each source of supply under a variety of water shortage conditions. This may include a determination that a particular source of water supply is fully reliable under most, if not all, conditions. (3) A comparison of the total water supply sources available to the water supplier with the total projected water use for the drought period.
(4) Considerations of the historical drought hydrology, plausible changes on projected supplies and demands under climate change conditions, anticipated regulatory changes, and other locally applicable criteria.

The City’s sources of supply consist primarily of groundwater from the San Jacinto Basin, which is managed by the Hemet-San Jacinto Watermaster, including both locally pumped groundwater and groundwater conveyed through EMWD’s system (wheeled supplies). The City also maintains access to treated imported water from MWD, delivered through EMWD. The following discussion provides a Drought Risk Assessment which assesses the City’s water supply reliability over a five consecutive year drought period. The City’s DRA incorporates a five consecutive year drought from CY 2011 through CY 2015 and includes a review of water supplies, water uses, and water supply reliability.

7.3.1 DRA DATA, METHODS, AND BASIS FOR WATER SHORTAGE CONDITIONS The City’s DRA was prepared using historical production data from the City’s water supply sources. The following assumptions were considered during the preparation of the City’s DRA for each year of the five consecutive year drought:
• The five consecutive year drought period associated with the 2025 UWMP is based on five consecutive dry years from CY 2026 through CY 2030. • The projected water supplies available during each year of this five consecutive year drought are assumed to be identical to the water supplies produced/available during each year between CY 2011 and CY 2015 (which represents the most recent and historical five consecutive year drought).
• The projected demands during this five consecutive year drought are based on water demands from CY 2025 (a normal year) which were adjusted based on projected population over the next five years along with the ratio of the normal year demands to actual demands over each year of the most recent and historical five consecutive year drought period (from CY 2011 and CY 2015).

14.B.

7-67
• The projected demands were compared to the projected supplies to identify potential water supply deficits which may require implementation of the Water Shortage Contingency Plan (discussed further in Chapter 8).

The following hypothetical methodologies were considered during the preparation of the City’s DRA during for each year of the five consecutive year drought:
• Drought Year 1: The region had experienced an average to above average year of precipitation in the prior year. Water use in the prior year had been below average due to a reduce need for outdoor water use, the groundwater basin had been replenished from above average local stormwater runoff and imported water supplies were not restricted.
• Drought Year 2: The region experienced a second year of below average precipitation and runoff. Retail customers increase water use for outdoor irrigation to compensate for lack of precipitation. Groundwater and imported water supplies have not been impacted. • Drought Year 3: The region experienced a third year of below average precipitation and runoff. Retail customers increase water use for outdoor irrigation to compensate for lack of precipitation. Groundwater and imported water supplies have not been impacted.

However, there is an increased demand on both groundwater and treated imported water.
• Drought Year 4: The region experienced a fourth year of below average precipitation and runoff. Groundwater supplies have not been impacted. However, there is an increased demand on groundwater.
• Drought Year 5: Fifth year of below average precipitation and runoff. Groundwater supplies have not been impacted. However, there is an increased demand on groundwater.

7.3.2 DRAFT WATER SOURCE RELIABILITY
The City’s DRA incorporates a five consecutive year drought based on five consecutive dry years commencing in CY 2021. The quantity of water supplies available for each year during this five consecutive year drought period included in the City’s DRA is assumed to be same as the quantity of water supplies produced by the City (i.e. demands) during the most recent and historical five consecutive year drought which occurred from CY 2011 through CY 2015. Production data for those years have been tabulated in Section 6.1. The following describes the anticipated reliability of each water source for each year of the five consecutive year drought based on recent experience.

14.B.

7-68
Groundwater – San Jacinto Basin
The City receives water supplies from the San Jacinto Basin which is actively managed by the Hemet-San Jacinto Watermaster, as described in Section 6.2.2. Each year the Hemet-San Jacinto Watermaster reviews water supply conditions including local rainfall, groundwater levels, local stormwater runoff available for replenishment, imported water availability and the amount of imported water stored in the groundwater basin for future demands. The Hemet-San Jacinto Watermaster identifies the annual amount of groundwater which may be pumped (such as an Operating Safe Yield) before more expensive imported water would need to be purchased from MWD through EMWD to replenish the San Jacinto Basin for all production in excess of the water rights. Regardless of the annual safe yield adopted there is never a restriction on the amount of water which may be pumped from the San Jacinto Basin, only the cost of producing the groundwater is impacted. The Hemet-San Jacinto Watermaster is not restricted as to when or how much untreated imported water will be delivered to the San Jacinto Basin, only that it ultimately be delivered. The quantity of groundwater used (and reliably available) during the most recent and historical five consecutive year drought period have been tabulated in Section

6.1. During this period, the City was able to increase its production of its groundwater supplies from an adjudicated and managed groundwater basin. The City also has the ability to systematically implement aspects of its Water Shortage Contingency Plan (see Chapter 8). As a result of these collective actions (and experience during prior five consecutive year droughts), the City does not anticipate a water supply shortage from the San Jacinto Basin.

Imported Water
The City may obtain imported water from MWD through EMWD. Section 6.2.1 describes the planning conducted by MWD regarding treated imported water supplies available to the City.

The reliability of MWD’s supplies is also discussed in its 2025 Regional UWMP and is incorporated by reference. The City can purchase treated imported water which is delivered directly within its distribution system. The City’s purchases of treated, imported water other the past ten years have been tabulated in Section 6.1. In the event of a drought which limits imported water supplies, the City will rely on its groundwater production and will pay the applicable assessments to purchase untreated imported water to be delivered in the future when supplies are available.

The imported water purchased by the City during the most recent and historical five consecutive year drought period have been tabulated in Section 6.1. Because the City’s DRA assumes the most recent and historical five consecutive year drought scenario will be repeated over the next five years, it is assumed the quantity of treated imported water supplies purchased during the most recent and historical five consecutive year drought scenario will be available. Furthermore, this constitutes the minimum amount of treated imported water which may be available in a future five consecutive year drought absent MWD’s programs which it has since implemented.

14.B.

7-69
Summary
The City’s water system has experienced a prior five consecutive year drought with no limitation to its collective water supplies. However, the cost of those water supplies may have increased based on the mix of supplies which are used. Consequently, the City has the ability to enact varying water shortage levels (see Chapter 8) to help educate its customers and provide an economic incentive for the retail customers to reduce their water consumption.

7.3.3 DRA TOTAL WATER SUPPLY AND USE COMPARISON
Gross water use for the projected five consecutive year drought is shown on Table 7-5. Section

7.3.2 describes the water source reliability for each source of supply the City will rely on during a five consecutive year drought. The annual quantities are summed and are also provided on Table 7-5. The most important aspect of the City’s water supplies is the groundwater which can be produced from a managed groundwater basin without restriction on the amount the City is allowed to produce. However, for the purposes of the City’s DRA, as a worst-case scenario, the City has considered no water supply augmentation (as indicated in Table 7-5) from its groundwater supplies. When necessary, the City can implement various water shortage levels of its Water Shortage Contingency Plan (as discussed in Chapter 8) in order to reduce its water demands. As shown in Table 7-5, assuming no additional water supply benefits will be available from groundwater supplies, the City will implement various of stages of its Water Shortage Contingency Plan to balance water demands with available supplies during years 1, 2, 3, 4, and 5 of the projected five consecutive year drought.

7.3.4 OPTIONAL PLANNING TOOL WORKBOOK
DWR has deemed the “Planning Tool Worksheet” as optional, and the City is not required by DWR to use the tool. The City has provided sufficient water supplies to its customers, including during long-term droughts and years with historically high water demands. The City has also been able to provide water service to meet maximum day water demands for these years, including during the summer months. The City obtains the majority of its water supplies from a managed groundwater basin which is not subject to seasonal fluctuation. Consequently, an evaluation regarding water supplies on a monthly basis was not considered.

Chapter 8 Water Shortage Contingency Plan
OVERVIEW – CHAPTER 8
Chapter 8 (Water Shortage Contingency Plan) of the City’s 2025 Plan discusses and provides the following:
• The City’s Water Shortage Contingency Plan is a detailed approach which presents how the City intends to act, or respond, in the case of an actual water shortage contingency. • Preparation of the City’s “Annual Water Supply and Demand Assessment” (or Annual Assessment) is discussed. The annual assessment is required to be submitted to DWR by July 1 of each year. The Annual Assessment includes a review of the City’s “unconstrained” water demands for the current year and for a potential upcoming single dry year. Unconstrained water demands represent the City’s water demands prior to any “response actions” the City may invoke pursuant to the City’s Water Shortage Contingency Plan.
• The City will manage water supplies to minimize the adverse impacts of water shortages.

The City’s plan for water usage during periods of shortage is designed to incorporate six standard water shortage levels corresponding to progressive ranges from up to a 10, 20, 30, 40, and 50 percent shortage, and greater than a 50 percent shortage. • For each declared water supply shortage level, customers will be required to reduce their consumption by the percentage specified in the corresponding water supply shortage level.
• For each declared water supply shortage level, the City has established response actions to reduce demand on water supplies and to reduce any shortage gaps in water supplies.

These demand reduction actions include irrigation and other outdoor use restrictions, rate structure changes, and other water use prohibitions. • The operational changes the City will consider in addressing water shortages on a shortterm basis are discussed and include improved monitoring, analysis, and tracking of customer water usage to enforce demand reduction measures. • The City’s Emergency Response Plan is summarized. The Emergency Response Plan provides the management, procedures, and designated actions the City and its employees will implement during emergency situations (including catastrophic water shortages) resulting from natural disasters, system failures, and other unforeseen circumstances. • The preparation of the City’s seismic risk assessment and mitigation plan is discussed. The locations of earthquake faults in the vicinity of the City’s water service area are provided.

14.B.

8-2
• The effectiveness of the shortage response actions for each of the City’s standard water shortage levels is presented. The City has been able to provide sufficient water supplies to its customers, including during five consecutive year droughts and years with historically high water demands.
• The communication protocols implemented by the City when it declares any water shortage level are presented.
• The compliance and enforcement procedures associated with City’s standard water shortage levels are presented.
• The legal authorities associated with City’s standard water shortage levels are presented. • The financial consequences associated with City’s standard water shortage levels are presented.
• The City will evaluate the need for revising the Water Shortage Contingency Plan in order to resolve any water shortage gaps, as necessary. The steps necessary for the City to adopt and amend its Water Shortage Contingency Plan are presented.

The following Water Shortage Contingency Plan includes references to Chapters and Sections from the City of Hemet’s 2025 Urban Water Management Plan:

8.1 WATER SUPPLY RELIABILITY ANALYSIS
CWC 10632.
(a)(1) The analysis of water supply reliability conducted pursuant to Section 10635.

The City’s sources of supply were discussed in Section 6.2 of the 2025 UWMP and consist of groundwater from the San Jacinto Basin and treated imported water purchased from EMWD. The San Jacinto Basin is adjudicated, and groundwater supplies are managed. The reliability of the various sources of supply are discussed in Chapter 7 of the 2025 UWMP. Based on the adjudication provisions in the San Jacinto Basin, the City is able to produce groundwater without limitation, provided an applicable assessment is paid to the Hemet-San Jacinto Watermaster to purchase untreated imported water for groundwater replenishment.

8.2 ANNUAL WATER SUPPLY AND DEMAND ASSESSMENT PROCEDURES CWC 10632.

(a)(2) The procedures used in conducting an annual water supply and demand assessment that include, at a minimum, both of the following:
(A) The written decision-making process that an urban water supplier will use each year to determine its water supply reliability.
(B) The key data inputs and assessment methodology used to evaluate the urban water supplier’s water supply reliability for the current year and one dry year, including all of the following:
(i) Current year unconstrained demand, considering weather, growth, and other influencing factors, such as policies to manage current supplies to meet demand objectives in future years, as applicable.
(ii) Current year available supply, considering hydrological and regulatory conditions in the current year and one dry year. The annual supply and demand assessment may consider more than one dry year solely at the discretion of the urban water supplier.
(iii) Existing infrastructure capabilities and plausible constraints. (iv) A defined set of locally applicable evaluation criteria that are consistently relied upon for each annual water supply and demand assessment. (v) A description and quantification of each source of water supply.

CWC 10632.1.

An urban water supplier shall conduct an annual water supply and demand assessment pursuant to subdivision (a) of Section 10632 and, on or before June 1 of each year, submit an annual water shortage assessment report to the department with information for anticipated shortage, triggered shortage response actions, compliance and enforcement actions, and communication actions consistent with the supplier’s water shortage contingency plan. An urban water supplier that relies on imported water from the State Water Project or the Bureau of Reclamation shall submit its annual water supply and demand assessment within 14 days of receiving its final allocations, or by June 1 of each year, whichever is later.

The City is required to submit an “Annual Water Supply and Demand Assessment” (Annual Assessment) in accordance with DWR’s guidance and requirements by July 1 of each year. The

14.B.

8-4
Annual Assessment includes a review of the City’s unconstrained water demands (i.e. water demands prior to any projected response actions the City may trigger under this WSCP) for the current year and the upcoming (potential single dry) year. The City will also include information regarding anticipated shortages, triggered shortage response actions, compliance and enforcement actions, and communication actions consistent with the City’s WSCP.

For each Annual Assessment, the City plans to prepare a preliminary assessment which evaluates the adequacy of its water supplies for the current and upcoming years by April of each year. The preliminary assessment will include a review of water supplies for at least a single dry year.

The components of an Annual Assessment consist of the following:
• A written decision-making process
• Key data inputs and assessment methodology

8.2.1 DECISION MAKING PROCESS
The City produces groundwater from the San Jacinto Basin as its primary source of water supply and that basin is managed on a fiscal year basis. Consequently, during the third quarter of each fiscal year the City will review its water demands from the initial six months along with the current groundwater basin conditions and local hydrology. This information will be used to help develop the Annual Assessment. A draft of the Annual Assessment will be circulated internally within the City for peer review and comment. Based on comments received, a redraft will be prepared and provided to City managers during the Spring of each year. The draft subsequently will be provided to the City Manager for final review. Subsequently, a final draft of the Annual Assessment will be provided to the City Council for review and included in the agenda as part of a City Council meeting such that it can be approved, and any recommended specific shortage response actions may be enacted. The final Annual Assessment will be provided to DWR no later than July 1 of each year.

The Annual Assessments will be instrumental in providing guidance to the City for decisions regarding potential declarations of a water supply shortage and implementation of water reduction stages, instituting mandatory water restrictions, promoting water use efficiency and conservation programs, water rates and drought rate surcharges, and the necessity of pursuing alternative water supplies. This process will help ensure adequate water supplies resources are available to the City.

14.B.

8-5

8.2.2 DATA AND METHODOLIGIES
The key data inputs and methodologies which will be evaluated by the City during the preparation of the preliminary assessment will include the following:
1) Evaluation Criteria: The locally applicable evaluation criteria used to prepare the Annual Assessment will be identified. The evaluation criteria will include, but is not limited to, an analysis of current local hydrology (including rainfall and groundwater levels), current water demands, a review of water system improvement plans which may impact infrastructure availability, and water quality regulations which may impact groundwater availability.
2) Water Supply: A description of each available water supply source will be provided. The descriptions will include a quantification of each available water supply source and will be based on review of current production capacities, historical production, Urban Water Management Plans, and prior water supply studies (including Water Supply Assessments and/or Master Plans).
3) Unconstrained Water Demand: The potential unconstrained water demands during the current year and the upcoming (potential single dry) year, prior to any special shortage response actions, will be reviewed. The review will include factors such as weather, existing and projected land uses and populations, actual customer consumption and water use factors, monthly Urban Water Supplier Monthly Reports, existing water shortage levels (see Section 8.3), and existing water conservation ordinances (see Section

9.2.1).
4) Planned Water Use for Current Year Considering Dry Subsequent Year: The water supplies available to meet the demands during the current year and the upcoming (potential single dry) year will be considered and identified by each type of supply. The evaluation will include factors such as estimated water demands, weather, groundwater basin operating safe yields, water quality results, existing available pumping capacities, imported water allocations, contractual obligations, regulatory issues, use of emergency interconnections, and the costs associated with producing each water supply source. 5) Infrastructure Considerations: The capabilities of the water distribution system infrastructure to meet the water demands during the current year and the upcoming (potential single dry) year will be considered. Available production capacities (e.g. groundwater well capacities) and distribution system water losses (see Section 4.2.4) will be reviewed. In addition, capital improvement and replacement projects, as well as

14.B.

8-6
potential projects which may increase water system and production capacities (see Section 6.2.8), will be considered.
6) Other Factors: Additional local considerations, if any, which can affect the availability of water supplies will be described.

8.3 SIX STANDARD WATER SHORTAGE LEVELS
CWC 10632.
(a)(3)(A) Six standard water shortage levels corresponding to progressive ranges of up to 10, 20, 30, 40, and 50 percent shortages and greater than 50 percent shortage. Urban water suppliers shall define these shortage levels based on the suppliers’ water supply conditions, including percentage reductions in water supply, changes in groundwater levels, changes in surface elevation or level of subsidence, or other changes in hydrological or other local conditions indicative of the water supply available for use. Shortage levels shall also apply to catastrophic interruption of water supplies, including, but not limited to, a regional power outage, an earthquake, and other potential emergency events.

The City has a legal responsibility to provide water utility services, including water for residential, commercial, industrial, public authority, and for public fire hydrants and private fire services. The City will manage water supplies prudently to minimize the adverse impacts of water shortages.

In 2018, two long-term water conservation bills, Senate Bill (SB) 606 and Assembly Bill (AB) 1668, were signed into law. The two bills amend portions of the California Water Code (CWC), including Section 10632, which is related to water shortage contingency planning. The amended CWC requires agencies to incorporate a WSCP under its Urban Water Management Plan (UWMP). It also specifies the adoption of six standard water shortage levels. This WSCP demonstrates the City’s compliance with the requirements outlined in CWC Sections 10632 and 10632.1.

The City’s six standard water shortage levels are summarized in the figure below. The City conducts annual assessments of supply conditions to determine the appropriate water shortage level, as outlined in Chapter 8– Annual Water Demand and Supply Assessment.

Water shortage levels also apply to interruption of water supplies, including but not limited to earthquakes, planned and unplanned facility outages, major water quality events, and other emergency events. For an expanded discussion of catastrophic water supply interruptions, refer to Section 8.4.

8.4 SHORTAGE RESPONSE ACTIONS
CWC 10632.
(a)(4) Shortage response actions that align with the defined shortage levels and include, at a minimum, all of the following:
(A) Locally appropriate supply augmentation actions.
(B) Locally appropriate demand reduction actions to adequately respond to shortages. (C) Locally appropriate operational changes.
(D) Additional, mandatory prohibitions against specific water use practices that are in addition to state-mandated prohibitions and appropriate to the local conditions. (E) For each action, an estimate of the extent to which the gap between supplies and demand will be reduced by implementation of the action.

8.4.1 DEMAND REDUCTION

8.4.2 SUPPLY AUGMENTATION
The City does not plan to add a new source of water supply to address customer demands, but instead will consider increased supplies from existing sources. Table 8-2 reflects this approach and does not identify any new supplies. Instead, the City will focus on demand reduction measures in the event existing sources of supply are not sufficient to meet customer demands.

As discussed in Chapter 6, the City’s sources of water supply include groundwater produced from the San Jacinto Basin and treated imported water purchased from MWD through Eastern Municipal Water District. As noted in Section 8.2 an annual assessment is required to be submitted to DWR by July 1 of each year. The Annual Assessment includes a review of water supplies available to meet water demands for the current and upcoming years. In the event the City is currently in, or considers entering into, one of the standard water shortage levels identified in Section 8.3, the City will consider the water supply augmentation actions described below.

For each water shortage level discussed in Section 8.3, the City will consider supplementing its existing water supplies through increased groundwater production instead of the purchase of additional imported water supplies. Due to previous critically dry conditions, MWD developed the Water Supply Allocation Plan whereby available supplies are equitably allocated to its member agencies, including Eastern Municipal Water District. The WSAP establishes ten different shortage levels and a corresponding drought allocation to each member agency. Based on the shortage level established by MWD, the WSAP provides a reduced drought allocation to a member agency for its Municipal and Industrial retail demand. The ratio of MWD water supply drought allocation to local water supply will change based on the WSAP stage. The MWD drought allocation can be used to make Full Service water deliveries at the Tier 1 rate up to a Tier 1 allocation. Any Full Service water delivered in excess of a drought allocation is subject to a penalty rate in addition to the normal rate paid for the water.

In addition to the WSAP, MWD describes supply augmentation actions in its Regional 2025 UWMP, which is incorporated by reference. MWD’s primary first response to any gap between core supplies (from the State Water Project and Colorado River) and demand is to make optimal use of its supply augmentation options, consisting of drawing from flexible supply programs and

14.B.

8-14
storage reserves. MWD has developed and actively manages a portfolio of water supply programs including water transfer, storage, and exchange agreements. MWD pursues voluntary water transfer and exchange programs to help mitigate supply/demand imbalances and provide additional dry-year supply sources. In addition, MWD has developed significant storage capacity in reservoirs, conjunctive use, and other groundwater storage programs totaling approximately

6.0 million AF. Pursuant to MWD’s “Emergency Storage Objective”, updated in 2019, approximately 750,000 AF of total stored water is emergency storage reserved by MWD for use in the event of supply interruptions. Based on MWD’s historical and on-going water supply and storage programs and management practices, the City will use up to the treated imported water supply made available from MWD through Eastern Municipal Water District in association with each of the standard water shortage levels identified in Section 8.3. Water demands will be addressed through increased use of local groundwater supplies and implementation of demand reduction measures through the various stages of action.

The City will consider augmenting its existing water supplies through production of additional groundwater from the San Jacinto Basin. As noted in Section 6.2.2, the San Jacinto Basin is managed by the Hemet-San Jacinto Watermaster. During the period of management under the San Jacinto Basin Judgment, significant drought events have occurred. In each drought cycle the San Jacinto Basin has been managed to maintain water levels. Parties to the San Jacinto Basin Judgment, including the City, are authorized to produce groundwater in excess of their rights and pay assessments for such production to the Hemet-San Jacinto Watermaster. The assessments are used to purchase untreated imported water to replenish the San Jacinto Basin. The HemetSan Jacinto Watermaster purchases untreated imported water to replenish the San Jacinto Basin from MWD through Eastern Municipal Water District. Groundwater quality is carefully monitored and managed by the Hemet-San Jacinto Watermaster. Treatment facilities and/or blend plans have been developed by water agencies to meet potable water standards and to prevent the spread of any groundwater contamination. Groundwater quality in the San Jacinto Basin is not expected to impact potable supplies or constrain supply reliability. Based on historical and ongoing management practices, the City will be able to continue relying on the San Jacinto Basin for adequate supplies in response to each of the standard water shortage levels identified in Section

8.3.

14.B.

8-15
Table 8-2 Supply Augmentation and Other Actions

8.4.3 OPERATIONAL CHANGES
During a water supply shortage situation, the City will manage its water supply resources to provide sufficient water supplies capable of meeting the demands of its customers. Section 8.4.1 describes the City’s standard water shortage levels and associated demand reduction measures.

Section 8.4.2 describes the City’s water supply sources and water supply augmentation actions available. The supply augmentation actions and demand reduction measures, when implemented, may potentially result in short-term operational changes which are necessary to allow the City to utilize all available water supply sources in response to water shortage situations.

As noted in Section 8.2, beginning July 1, 2022, the City will prepare and submit an Annual Assessment which will include a review of the water supplies available to meet water demands for the current and upcoming years. Preparation of the Annual Assessment will assist the City in determining any potential operational changes. In addition, the City’s standard water shortage levels and the associated demand reduction measures, in conjunction with the City’s existing Demand Management Measures (DMMs) (discussed in Chapter 9), will be essential to the City in

14.B.

8-16
reducing water demands during any water shortage period. The operational changes the City will consider in addressing non-catastrophic water shortages on a short-term basis include the following:
• Improved monitoring, analysts, and tracking of customer water usage to enforce demand reduction measures
• Optimized production from existing available water supply sources • Potential use of emergency supply sources, including emergency interconnections • Potential blending of water supply resources
• Improved monitoring, maintenance, and repairs to reduce water distribution system losses

8.4.4 ADDITIONAL MANDATORY RESTRICTIONS
The mandatory restrictions which are implemented by the City to reduce customer demands are discussed in Section 8.4.1. There are no additional mandatory restrictions planned at this time.

8.4.5 EMERGENCY RESPONSE PLAN
Catastrophic water shortages are incorporated in the City’s standard water shortage levels (identified in Section 8.3) and the associated demand reduction measures (described in Section

8.4.1). In addition to the water supply augmentation actions (Section 8.4.2) and potential operational changes (Section 8.4.3) which the City may consider in order to continue providing sufficient water supplies, the City will review and implement any necessary steps included in its “Emergency Response Plan”.

As part of the “America’s Water Infrastructure Act of 2018”, community water systems serving a population greater than 3,300 people, including the City, are required to review and update their “Risk and Resilience Assessment” (RRA) and the associated “Emergency Response Plan” (ERP) every five (5) years.

The City’s RRA, prepared in 2021, evaluates the vulnerabilities, threats, and consequences from potential hazards to the City’s water system. The City prepared its RRA (which is incorporated by reference) by evaluating the following items:
• Natural hazards and malevolent acts (i.e., all hazards);

14.B.

• Resilience of water facility infrastructure (including pipes, physical barriers, water sources and collection, treatment, storage and distribution facilities, and electronic, computer and other automated systems);
• Monitoring practices;
• Financial systems (e.g., billing systems);
• Chemical storage and handling; and
• Operation and maintenance.

The City’s RRA evaluated a series of potential malevolent acts, natural hazards, and other threats in order to estimate the potential “monetized risks” (i.e. associated economic consequences to both the water system and surrounding region, and the likelihood of occurrence) associated with the City’s water facility assets. The cost-effectiveness of implementing potential countermeasures to reduce risks was also reviewed.

The City’s ERP was completed in 2021 and provides the management, procedures, and designated actions the City and its employees will implement during emergency situations (including catastrophic water shortages) resulting from natural disasters, system failures and other unforeseen circumstances. The City’s ERP (which is incorporated by reference) provides the guidelines for evaluating an emergency situation, procedures for activating an emergency response, and details of the different response phases in order to ensure that customers receive a reliable and adequate supply of potable water. The scope of the ERP includes emergencies which directly affect the water system and the ability to maintain safe operations (such as a chlorine release, and earthquake or a threat of contamination). The ERP also incorporates the results of City’s RRA and includes the following:
• Strategies and resources to improve resilience, including physical and cybersecurity • Plans and procedures for responding to a natural hazard or malevolent act • Actions and equipment to lessen the impact of a natural hazard or malevolent act • Strategies to detect natural hazards or malevolent act The City will review the ERP for procedures regarding the utilization of alternative water supply sources in response to water supply shortages, including during the standard water shortage levels. The City will also review applicable procedures described in the ERP regarding any necessary temporary shutdown of water supply facilities, including appropriate regulatory and public notifications.

8.4.6 SEISMIC RISK ASSESSMENT AND MITIGATION PLAN
CWC 10632.5.
(a) In addition to the requirements of paragraph (3) of subdivision (a) of Section 10632, beginning January 1, 2020, the plan shall include a seismic risk assessment and mitigation plan to assess the vulnerability of each of the various facilities of a water system and mitigate those vulnerabilities.
(b) An urban water supplier shall update the seismic risk assessment and mitigation plan when updating its urban water management plan as required by Section 10621. (c) An urban water supplier may comply with this section by submitting, pursuant to Section 10644, a copy of the most recent adopted local hazard mitigation plan or multihazard mitigation plan under the federal Disaster Mitigation Act of 2000 (Public Law 106-390) if the local hazard mitigation plan or multihazard mitigation plan addresses seismic risk.

The County of Riverside prepared a “Multi-Jurisdictional Local Hazard Mitigation Plan” which was approved by the Federal Emergency management Agency (FEMA) in April 2023. The County’s Multi-Jurisdictional Local Hazard Mitigation Plan identified methods to assess significant natural hazards (including earthquakes) affecting areas throughout Riverside County, and the mitigation strategies necessary to reduce risks, including seismic risk. The County’s Multi-Jurisdictional Mitigation Plan is provided in Appendix L. The California Geological Survey has published the locations of numerous faults which have been mapped in the Southern California region.

Although the San Andreas fault is most recognized and is capable of producing an earthquake with a magnitude greater than 8 on the Richter scale, some of the lesser-known faults have the potential to cause significant damage. The locations of these earthquake faults in the vicinity of the City’s water service area are provided in the figure below. The faults that are located in close proximity to and could potentially cause significant shaking in the City’s water service area include the San Andreas fault, the San Jacinto fault, and the Beaumont Plain fault.
