City Manager Cortez shared that once the budget is approved, they will then start negotiations with the unions.
Dr. Resendiz reminded the public that the City Council is the only one that holds the power to make these decisions.
Finance Director O'Connell stated that the budget is a measuring tool. We are in a financial emergency and have a policy that states we need a 20% reserve. We have already dipped into the reserves; in order to stay afloat, there are not many other options.
Council Member Picha stated that the council does give policy direction to the City Manager, however, they are accountable to their constituents, the residents of Hollister.
By consensus, the council unanimously directed staff to move forward with the proposed 0% reserve.
Provide direction on General Fund Reserve goals.

HOLLISTER CITY COUNCIL
MEETING DATE: June 15, 2026
REPORT # Public Works -2026-33
AGENDA ITEM: A RESOLUTION ADOPTING THE 2025 SAN BENITO URBAN
WATER MANAGEMENT PLAN
DEPARTMENT: Public Works
DEPARTMENT HEAD: Javier Hernandez, Public Works Director COUNCIL NEXT STEPS: Adopt a resolution adopting the 2025 San Benito Urban Water Management Plan.
DISCUSSION: California Water Code Section 10610 et seq., known as the Urban Water Management Planning Act ("Act"), requires urban water suppliers to prepare and adopt an Urban Water Management Plan ("UWMP") every five years. The purpose of the UWMP is to support long-term resource planning and ensure adequate water supplies are available to meet existing and future demands.
The San Benito County Water District ("District") has participated cooperatively with the City of Hollister, the City of San Juan Bautista, and the Sunnyslope County Water District (the "Participating Agencies") in preparation of the 2025 San Benito Urban Water Management Plan ("Plan"). The Plan evaluates water supply reliability and projected demands within the San Benito Urban Area, which includes the service areas of the participating agencies and the surrounding areas overlying the North San Benito Groundwater Basin.
The Plan identifies and quantifies existing and future water supplies, evaluates water reliability under normal, single dry -year, and multiple dry -year conditions, and includes water conservation and water shortage contingency planning measures as required by State law.
The UWMP is intended as a planning document and resource management tool. The Plan does not create water rights, entitlements, or guarantees of service, nor is it intended to serve as the sole basis for land use entitlement decisions. Water availability and reliability must continue to be evaluated on a project -by -project basis as part of development review processes.
Upon adoption by all Participating Agencies, the District will:
• Deliver the final adopted Plan to the City of Hollister, City of San Juan Bautista, and County of San Benito within sixty (60) days of adoption; • File the adopted Plan with the California Department of Water Resources by July 1, 2026;
• Continue implementation of water conservation and water shortage contingency programs through the District's annual budgeting and operational processes.
Once approved by all Participating Agencies, the Plan will be made available for public
review at the District Office located at 30 Mansfield Road, Hollister, California.
Preparation of the Urban Water Management Plan has been funded through the District's existing budget appropriations and cooperative cost -sharing efforts among participating agencies. Adoption of the Plan does not authorize additional capital expenditures.
Lastly, the District has posted the required public notification, on May 22nd and May 29th of 2026, of this adoption hearing on the 2025 San Benito Urban Water Management Plan in accordance with the Urban Water Management Planning Act.
FISCAL IMPACT: No new fiscal impact.

PURPOSE AND SCOPE
The 2025 San Benito Urban Areas (SBUA) Urban Water Management Plan (UWMP) had been prepared as a collaborative effort among the San Benito County Water District (District or SBCWD), Sunnyslope County Water District (Sunnyslope or SSCWD), City of Hollister (Hollister), and City of San Juan Bautista (SJB). The plan has been prepared in accordance with the Urban Water Management Planning Act and guidelines prepared by the Department of Water Resources (DWR). The 2025 SBUA UWMP is intended to help guide the area's future water management efforts.
This 2025 UWMP Plan builds on and updates the 2020 UWMP, accounting for changes in the California Water Code and local planning and water management efforts. Updates include the Drought Reliability Assessment, quantification of demand reduction in the Water Shortage Contingency Plan, and detailed consideration of supply reliability by source. Since the previous update, changes have occurred to the Hollister Urban Area (HUA), specifically the extension to include the City of San Juan Bautista (SJB), which is expected to occur in the next two years. Because SJB has fewer than 3,000 connections, SJB has had no requirement to prepare a UWMP in the past. The 2025 UWMP encompasses the combined service areas, which will hereafter be referred to as the San Benito Urban Areas (SBUA).
The SBUA agencies have provided agency coordination and community participation in their urban water management planning efforts. Much of the coordination and community participation regarding water conservation within the SBUA is undertaken by the agency members of the Water Resources Association (WRA) of San Benito County. The WRA serves water customers of Hollister, Sunnyslope, SJB, and the District. The WRA has played an integral role in the preparation of this UWMP.
This UWMP presents the following elements relating to water supply and demand in the SBUA:
1. A description of the SBUA service area, which is a regional partnership consisting of the District, Sunnyslope, Hollister, and SJB.
• Past and current water demand as reported by the agencies in the SBUA. • Water Loss Audit consistent with AWWA methodology.
• Baseline daily per capita water demand, as required by Senate Bill 7. • Projected water demand based on estimated population and per capita daily demand reductions as required by Senate Bill 7.
• A summary of sources of water supply and plans for future water supply facilities. • Discussion of water supply reliability and comparison of supply and demand, including the effects of drought and emergencies on water supply availability, and the contingency plans in place to manage shortages.
• Details of the demand management measures employed within the SBUA.

FINDINGS
In 2023, the area used in the 2010, 2015 and 2020 UWMPs was updated in the San Benito Urban Area Water Supply and Treatment Master Plan Update (Master Plan). The new study area, used in this 2025 UWMP, includes the original Hollister Urban Area boundary and has incorporated the City of San Juan Bautista. There are three municipal water purveyors within the SBUA: the City of Hollister, Sunnyslope County Water District, and the City of San Juan Bautista. These water purveyors provide water supply to their individual service areas from sources described in Section 6 of this report. The District has the responsibility and authority to manage groundwater in San Benito County, which includes managing groundwater and surface water supplies. In addition, the District holds the contract for water through the Central Valley Project (CVP) and is the imported water wholesaler from the CVP to Zone 6, which includes most of the SBUA. Current and projected population and potable water demand values for the SBUA are shown in Table ES -1 below. The Water Supply Reliability and Drought Risk Assessment, in Section 7, concludes that the SBUA has supply to meet demand in most years. However, additional conservation or supply may be required in dry conditions in 2045. The agencies are currently involved in several projects to increase supply reliability (Section 6.2.10) and decrease demand (Section 9). 2025

The annual estimates for the population of the SBUA (where water is supplied by Sunnyslope, Hollister, and SJB) were updated through 2025. The 2025 population is based on data from the Department of Drinking Water (DDW) and the forecasted population estimates are from the 2023 SBUA Water and Wastewater Master Plan (Master Plan).
Population for the SBUA was also estimated through 2045 in five-year intervals. Future population was estimated as part of the Master Plan through examination of general development plans for the City of Hollister and San Benito County, and the addition of SJB. These population growth estimates were based on the Master Plan (which utilizes a population growth rate of 3.5%), as described in Section 4.2.5.1.
San Benito Urban Areas UWMP 2025
Page ES -2
BASELINE AND FUTURE WATER DEMAND
Historical population was combined with measured water use to calculate baseline per capita daily demand for the SBUA, in accordance with DWR guidelines and Senate Bill 7.
Hollister and Sunnyslope met the 2020 demand reduction targets. SJB was not included in the 2020 UWMP and therefore did not set a 2020 demand reduction target. Discussions of the target water demands are presented in Section 5.
Future water demands have been calculated based on the target water use values and the population projections summarized above and described in detail in the relevant sections. The resulting annual water demands are summarized in Table ES -1. As indicated, water supply is projected to meet water demand in all normal years and in all single dry years until 2045 when a 13% shortfall is projected. At that time, the SBUA may need to develop additional water supplies or enact its Water Shortage Contingency Plan (WSCP) to reduce water demand.
WATER SUPPLY
The SBUA relies on local groundwater, imported water from the CVP, and recycled water for municipal water supply. The District manages all CVP imports for both agricultural and municipal and industrial (M&I) water deliveries. The District also manages the groundwater resources of the County, particularly the highly developed basins in the northern county, where District activities include managed aquifer recharge, monitoring groundwater levels and water quality, and annual reporting. The North San Benito Groundwater Basin is subject to the 2014 Sustainable Groundwater Management Act, which required the development of a Groundwater Sustainability Plan (GSP) by 2022. The North San Benito GSP was submitted in January 2022 and approved by DWR in July 2023.
Since the initiation of CVP importation and the construction and expansion of surface water treatment plants (WTPs, including Lessalt and West Hills), the use of groundwater for M&I supply has declined.
However, the basin provides significant storage, and groundwater remains a major source of supply, particularly during droughts. In the last drought (2021 through 2023), groundwater accounted for approximately 60 percent of the total water supplied by Hollister and Sunnyslope. The City of San Juan Bautista relied 100 percent on groundwater for their supply during this time. In the future, SJB will be part of the CVP system, and will receive imported water. However, they are anticipated to use groundwater to supplement supply, especially during drought. The District's management has resulted in a reliable and sustainable groundwater resource, although groundwater quality is recognized as lower quality than CVP in terms of salinity, hardness, and other constituents as documented in the GSP. In 2024, a normal year, groundwater was 30 percent of supply.
Blending groundwater with CVP imported water helps the SBUA address various water quality issues. The quality of groundwater has been described as highly mineralized and of marginal quality for drinking and agricultural purposes. Because of this less -than -desirable water quality, groundwater has been blended with CVP supply since construction of the WTPs; the Master Plan recommends that groundwater be less

than a third of supply. This goal is to achieve better water quality for supply and wastewater but this recommendation may be temporarily relaxed during drought conditions. The District's contract for M&I CVP deliveries with the United Stated Bureau of Reclamation (USBR) is 8,250 AFY, including users outside of the SBUA. While municipal WTP capacity has been expanded to allow increased M&I use of CVP supplies, future CVP supply will continue to be constrained by USBR allocations. Simulated future M&I allocations (through 2050) could be reduced to as much as 33 percent in dry years, based on observed conditions.
WATER SUPPLY RELIABILITY
Multiple factors could result in shortages and inconsistency of supply, including legal, environmental, water quality, climatic, or a combination of these. Hollister, Sunnyslope, SJB, and the District are preparing for these threats to water supply by expanding their portfolio of supplies, improving facilities (e.g., treatment plant expansion and aquifer storage recharge (ASR)), and supporting demand management.
Section 7 presents a detailed discussion of the factors affecting water supply, the steps taken by the SBUA agencies to address these factors, and a comparison of supply and demand during water shortages caused by drought. The Drought Reliability Assessment (DRA) tool provided by DWR additionally quantifies the expected demand and supply for the near future.
WATER CONSERVATION
The SBUA agencies developed a Water Shortage Contingency Plan (WSCP) as part of the 2015 UWMP. In response to new requirements, the ability of the SBUA to reduce demand when faced with water shortages is described in Section 8 with further detail and quantification. In addition to shortage -related prohibitions, the agencies have many ongoing programs to encourage water conservation. These programs, discussed in depth in Section 9, were successful in reducing water demand by more than 25 percent to meet the state mandated water use reduction in the 2014-2016 drought. To meet the future water use per capita demand targets, the SBUA and WRA, through their water conservation coordinator, plan to focus their efforts on several demand management measures (DMMs) including public outreach, rebates, and turf removal programs. These specific DMMs are targeted as opportunities for maximum water savings.

This Urban Water Management Plan (UWMP or Plan) has been prepared for the San Benito Urban Areas (SBUA) to help guide the area's water management efforts beyond the year 2025. The SBUA covers all of the City of Hollister, all of the City of San Juan Bautista, and some of the unincorporated areas beyond each of the city limits. The San Benito Urban Areas UWMP is a collaborative effort among the City of Hollister (Hollister), Sunnyslope County Water District (Sunnyslope), the City of San Juan Bautista (SJB) and San Benito County Water District (District). The Plan has been prepared in accordance with the Urban Water Management Planning Act (Division 6 Part 2.6 of the Water Code §§10610 — 10656). The location of the SBUA is shown in Figure 1-1.
This Plan builds on and updates the 2020 UWMP, accounting for changes in the California Water Code and local planning and water management efforts. Major changes include the addition of SJB to the plan area, expanded discussion of water loss, and individual agency tables uploaded to the DWR WUE portal.
A complete review of the changes for the 2020 UWMP is included in the DWR UWMP Guidelines in Appendix B.

2.1 PLAN PREPARATION AND ADOPTION
This Plan documents sources of water supply for Hollister, Sunnyslope, and SJB, defines water demands, presents a water shortage contingency plan, describes implementation of water demand management measures, and projects water supply and demand to the year 2045. The plan describes ongoing work by the District to ensure and expand water supply in the area. The three water systems, their connections, and 2025 water supply are documented in Table 2-1.
As indicated in Table 2-2, the SBUA represents a regional alliance, as defined by Water Code sections 10608.20(a)(1) and 10608.28. Hollister, Sunnyslope, and SJB choose to plan, comply, and report on a regional basis. Where possible, information for each entity is displayed individually in addition to the regional totals for the entire SBUA.
The SBUA regional alliance is made up of the three retailers (Hollister, Sunnyslope, SJB) and a wholesaler (the District), which is indicated in Table 2-3 as required. Where applicable, the requirements for retailers and wholesalers are addressed. Because the four agencies work together in preparation of future water demands and supply, Tables 2-4 R and 2-4 W have been updated to reflect that they are aware of each other's planning process. (Note that R indicates Retailer and W indicates Wholesaler.) Throughout the 2025 UWMP, units are in acre-feet and data are presented in calendar years, unless otherwise stated (Table 2-3). Water volumes and other data are shown to the nearest acre-foot (AF).
These values are accurate to one to three significant digits, depending on the measurement. Values in the text may show more significant digits than are warranted to maintain as much precision as possible during subsequent calculations; however, results of calculations have been rounded to the appropriate number of significant digits.
In accordance with section 10642 of the Water Code and section 6066 of the Government Code, each agency held a public hearing prior to adoption of the Plan. A public notice was posted before the public hearing and included in Appendix A. The Final Plan will be adopted by Hollister on June 15, 2026, SJB on June 16, 2026, Sunnyslope on June 23, 2026, and the District on June 24, 2026.
The resolutions to adopt the Plan are included in Appendix A. The adopted Plan has been filed with the Office of Conservation in the Department of Water Resources and California State Library, as required by law. California regulations require Urban Water Management Plans to be updated at least once every five years, in years ending in five and zero. However, DWR extended the deadline for the 2025 UWMP to July 1, 2026.

2.2 AGENCY COORDINATION AND PUBLIC PARTICIPATION
The SBUA agencies have provided for agency coordination and community participation in their urban water management planning efforts. A Draft Plan was made available to the public in June 2026 for comment with public presentations to the Hollister City Council on June 15, 2026, SJB City Council on June 16, 2026, Sunnyslope Board of Directors on June 23, 2026, and the District Board of Directors on June 24, 2026.
The Water Resources Association of San Benito County (WRA) is an ongoing means for agency coordination and public participation, focused on water conservation. The WRA serves water customers of the following agencies: City of Hollister, City of San Juan Bautista, Sunnyslope County Water District, and San Benito County Water District. The WRA coordinates and conducts water conservation programs for its participating member agencies and maintains an active website, www,wrasbc,org.
The Draft Plan was sent to local organizations with a request to provide comments, including San Benito County. Final Plan copies are available at Hollister City Hall, San Juan Bautista City Hall, and the City of Hollister Library. An electronic version is available on the websites of all four agencies (Hollister, Sunnyslope, SJB and the District).
2.3 ACKNOWLEDGEMENTS

3.1 GENERAL DESCRIPTION
The SBUA is located about 90 miles south of San Francisco in the northern portion of San Benito County, California. The SBUA is in a broad valley between the Gabilan Range on the west and the Diablo Range on the east. As shown in Figure 1-1, the San Benito River runs through the southwestern portion of the SBUA and Santa Ana Creek flows through the eastern portion of the SBUA. The Arroyo de Las Viboras and Arroyo Dos Picachos flow to the northeast of the SBUA. The City of Hollister, incorporated in 1872, is the largest community in San Benito County and San Juan Bautista, incorporated in 1896, is the second largest community. Other communities near the SBUA include Tres Pinos, which is also in San Benito County, and Gilroy in Santa Clara County. The SBUA overlies a portion of the Gilroy -Hollister groundwater basin, designated as DWR Basin No. 3-003.05.
3.2 SERVICE AREA
The service area was formerly known as the Hollister Urban Area (HUA) and was used in the previous 2010 UWMP (Todd 2011), 2015 UWMP (Todd 2016), the Water and Wastewater Master Plan (HDR 2008a and HDR 2017), and 2020 UWMP (Todd 2021). The area has been updated in the Water and Wastewater Master Plan in 2023 (HDR 2023) and is adopted in this 2025 UWMP update. The new study area includes the original Hollister Urban Area boundary, has incorporated the San Juan Bautista city limit, and is now referred to as the San Benito Urban Areas (SBUA). The SBUA is an approximately 20 square mile area comprising all of the incorporated, and some unincorporated county lands surrounding the City of Hollister, and City of San Juan Bautista (Figure 1-1).
There are three municipal water purveyors within the SBUA: the City of Hollister (Hollister), Sunnyslope County Water District (Sunnyslope), and the City of San Juan Bautista (SJB). These water purveyors provide water supply to their individual service areas from sources described in Section 4 of this report. The year 2025 service areas for Hollister, Sunnyslope, and SJB are shown on Figure 3-1.
The District was formed by a special act of the State with responsibility and authority to manage groundwater in San Benito County. As part of its management activities, the District manages recharge to the basin, explores expanded groundwater banking, monitors water levels and water quality, and reports annually on the basin. In addition, the District is the imported water wholesaler from the CVP to Zone 6, the northern portion of the County. SBUA is located mostly within Zone 6.
3.3 CLIMATE
San Benito County has a moderate California coastal climate, with a hot and dry summer season typically lasting from May through October. Average annual rainfall ranges from 7 inches in the drier eastern portion of the County to 27 inches per year in high elevations to the south (PRISM, 2025). The City of Hollister, some 30 miles inland from the coast and separated from it by the Gabilan Range, receives an annual average rainfall of about 13.08 inches (Todd 2026). Snowfalls in the mountains are infrequent and
SIMIRMIAMMURVAMMUMENAMMEMMUMENAMMUMMMUMENAMMUMMMUNMMMUMMMUMENAMMUMMMUMENAMMEMMEMMEMMUMENAMMUMMMUMENAMMEMMEMMEMMUMENAMEM San Benito Urban Areas UWMP 2025
relatively light. A comparatively long growing season of 265 days or more per year prevails, and year- round cropping is practiced to some extent. The area has a high percentage of sunny days, particularly in summer. Most of the rainfall occurs in late fall, winter, and early spring, generally between November and April. Therefore, significant irrigation is required during summer months (HDR 2017). Climate change and its effects on water demands and supplies are addressed in Sections 4 and 6.
Figure 3-2 is a graph of annual rainfall in Hollister from 1975 to 2025. While rainfall data have been collected monthly since 1875, precipitation and other weather data have been collected since June 1994 from a California Irrigation Management Information System (CIMIS) station located by the San Benito County Water District office in Hollister (Station #126). As shown, annual precipitation is subject to wide annual variations.
Evapotranspiration (ET) is the loss of water to the atmosphere by evaporation from soil and plant surfaces and transpiration from plants. It is an indicator of how much water is needed by plants (e.g., crops and landscaping) for healthy growth and productivity. ET from a standardized well -watered grass surface is the common reference, denoted as ETo. The least ET occurs in the cool wet winter months and greatest ET occurs during the hot dry summer months. This results in peak monthly water demands in summer that are three times the comparable winter demand. Average annual ETo in the SBUA is 49.73 inches, peaking at 6.2 to 6.9 inches per month in June, July, and August (CIMIS 2026).
Average monthly temperatures in the SBUA range from approximately 48 degrees Fahrenheit in January and December to near 65 degrees in July and August. In these two months, daily maximum temperatures typically reach as high as 86 degrees (CIMIS 2026).
.4 POPULATION
The SBUA is the urban center of a highly productive agricultural area that has been in continuous production for over one hundred years. The primary industry of the SBUA is agriculture and agriculture related businesses, although in recent years there has been an increase in the number of residents who commute to other areas for work. The area is characterized primarily by single family residences, with less than 19 percent and 9 percent of the population in multifamily dwellings, for Hollister and Sunnyslope respectively.
Tables 3-1 Hollister Retail, 3-1 Sunnyslope Retail, 3-1 SJB Retail show the population for 2025 through 2045 in five-year increments for Hollister, Sunnyslope, and SJB respectively. The current population is based on the information reported to the Department of Drinking Water (DDW). Population is anticipated to increase in the coming years, as planned developments are constructed. The 2025 through 2045 populations for Hollister, Sunnyslope, and SJB are based on the projected growth in the 2023 Master Plan,
3.5 percent increase per year. For SJB, estimated population is based on these regional estimates; however, expected water demand is based on the City's current planning and their specific General Plan.
These data are in line with the Water and Wastewater Master Plan population projections (HDR 2023).
The future population and water demand estimates are discussed in more detail in Section 4.2.
RIMMAMMUMMUARMARMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARM San Benito Urban Areas UWMP 2025
Based on the number of connections and the data available from the DWR population tool, the respective household size for single family and multiple family residences are 3.3 and 18.37 people per connection for Hollister, 3.45 and 10.03 people per connection for Sunnyslope; no information was provided for SJB.
Information about the projected connections is discussed in Section 4.2. While the District is a wholesaler of CVP water to the SBUA, it does not provide urban water supply directly in the SBUA. Table 3-1 W shows the total population of the three retailers (Hollister, Sunnyslope, and SJB) served by the District.
Additional increases in population are expected to occur in the unincorporated part of the county, outside the SBUA. Hollister, Sunnyslope, and SJB have no plans to serve this increase, and thus, these increases are not included in the future population or future demand calculations. However, it is recommended that development in neighboring areas continue to be tracked as increases in groundwater pumping for these developments may impact groundwater resources of the SBUA.
Demographic, social, and economic trends and shifts may affect water management and planning decisions, such as creating appropriate water programs based on the needs of specific socioeconomic factors. The overall poverty rate in San Benito County is 7.2% based on the most recent American Community Survey 2024 one-year estimates (U.S. Census Bureau). Meanwhile, the median income of all households is $114,011. The population identifies as about 63 percent Hispanic, 27 percent White, 5 percent Asian, less than 1 percent Black, and 4 percent as other. Of the population 5 years and older, 44.1 percent speaks a language other than English at home. The highest educational attainment breakdown(for 25 and older population) includes 15 percent for twelfth grade with no diploma, 29 percent for high school graduate, 29 percent receiving some college education, 19 percent with a bachelor's degree, and 8 percent with a graduate degree. This is important information when considering language and content for public outreach of water programs.
3.5 LAND USES WITHIN SERVICE AREA
GIS-based land use maps are available online with the DWR Land Use Viewer (DWR 2026), Figure 3-3. The current land use in the SBUA is dominated by natural and idle lands, which make up 36 percent of the service area by acreage. This refers to lands that are idle, non -vegetated or covered by water or grass and brush. Agricultural and pastural lands cover 29 percent of the service area and include lands used for vineyards, small vegetables, deciduous orchards, irrigated field crops, non -irrigated pastures, and non - irrigated grains. Urban residential lands cover 23 percent of the SBUA, while rural residential areas are only 2 percent by acreage. Other urban land uses include commercial, industrial, turf and vacant urban land, which cover 11 percent of the service area by acreage. Based on the Groundwater Sustainability Plan and the County General Plan outlined in the Water and Wastewater Master Plan, anticipated changes in future land use include converting natural vegetation or agricultural use to urban growth (HDR 2023).
Future development is expected to be somewhat denser than the existing urban area. Because of this, urbanization will likely occur at a slower rate than population growth. Other anticipated land use changes include some expansion of vineyard acreage, although at a slower rate than present, as recent industry trends suggest a slowing of grape production in California.

Past, current, and projected water demands are presented in this section for Hollister, Sunnyslope, and SJB. Current water demand is provided by water use sector and projected to 2045 in five-year increments.
Current system losses are also provided and projected to 2045.
4.1 NON -POTABLE VERSUS POTABLE USE
Non -potable water accounts for only a small portion of water use within the SBUA as shown in Tables 4- 1 Retail (for Hollister) and Wholesale (for total SBUA including other M&I users supplied by the District).
In 2025, 2 percent of water supplied to Hollister and 1.3 percent for the entire SBUA was non -potable water, most of which is used for municipal irrigation. The source of non -potable water is disinfected tertiary recycled water provided from the domestic wastewater treatment plant/water reclamation facility (DWWTP/WRF) for the City of Hollister. This recycled water is currently being used for irrigation at one site within the SBUA (80 AF in 2025). While there are no plans to increase recycled water use for municipal use in the SBUA, additional recycled water is supplied to areas outside of the SBUA for agricultural irrigation (Todd 2025). The municipal non -potable use by Hollister is reflected in Tables 4-2 showing projected total water use of potable and non -potable waters in five-year increments through 2045. There is no Indirect Potable Reuse (IPR) in the SBUA and none is planned.
4.2 PAST, CURRENT, AND PROJECTED WATER USE BY SECTOR
4.2.1 WATER USE BY SECTOR
Tables 4-1 Hollister Retail, 4-1 Sunnyslope Retail, and 4-1 SJB Retail show the number of water service accounts and delivery volumes by customer type in 2025 for Hollister, Sunnyslope, and SJB respectively.
In recent years, the number of accounts (specifically residential connections) increased in both the Hollister and Sunnyslope service areas. Hollister, Sunnyslope, and SJB water connections are classified into seven water use categories, which are described below along with selected California Water Code (CWC) citations:
• Single-family residential - A single-family dwelling unit. A lot with a free-standing building containing one dwelling unit that may include a detached secondary dwelling. • Multi -family - Multiple dwelling units contained within one building or several buildings within one complex. It should be noted that the number of multi -family accounts is not the same as the number of multi -family units because one connection could supply multiple units. • Commercial - A water user that provides or distributes a product or service. CWC 10608.12 (e).
This category also includes institutional uses. This type of user includes, among other users, higher education institutions, schools, courts, churches, hospitals, government facilities, and nonprofit research institutions. CWC 10608.12 (j).
2. Industrial - A water user that is primarily a manufacturer or processor of materials as defined by the North American Industry Classification System (NAICS) code sectors 31 to 33, inclusive, or an SitaRMIRMUNMEMMUNMEMMUNMEMMMUMMUMMUMMUMMUMMUNMMUMMUMMUMMUMMUMMUMMUMMUMMUMMUNMEMMEMMUNMMUMMUMMUNMEMMUMMUMMURVAMMUNMEMMUMENNMEM San Benito Urban Areas UWMP 2025
entity that is a water user primarily engaged in research and development. CWC 10608.12 (i). The following link is to the NAICS website: https://www,censusegov/naics/ . • Landscape - Water connections supplying water solely for landscape irrigation. Such landscapes may be associated with single-family residential, multi -family residential, commercial, industrial, or institutional/governmental sites, but are considered a separate water use sector if the connection is solely for landscape irrigation.
• Landscape (recycled water) - Includes meters that only use recycled water solely for landscape irrigation.
• Distribution System Losses - Reporting of system losses is required in the 2025 UWMPs. • Optional — Other uses (e.g., construction water uses) also may be reported.
In addition to the demand of the three retailers, the District provides an additional 200 AFY to other M&I users in area. Table 4-2 W shows the total projected use for the SBUA, including the three retailers and the volume that the District delivers directly.
4.2.2 WATER USE SECTORS IN ADDITION TO THOSE LISTED IN WATER CODE Other water use sectors (such as sales to other agencies, groundwater recharge, and conjunctive use) are not performed by the retailers in the SBUA at this time, are not planned in the future, and are not included in these demand tables. As described in Section 6, the District conducts extensive groundwater management, including conjunctive use and groundwater recharge, as part of its water supply programs.
4.2.3 PAST WATER USE
The delivery volumes by customer type for Hollister, Sunnyslope, and SJB from 2000 through 2025 are illustrated respectively in Figures 4-1 through Figure 4-3. Total water deliveries for the SBUA are shown in Figure 4-4. The number of water service connections and volume of water served provide insight into water use amounts and trends associated with different types of users, which can be useful in defining effective water conservation measures. As shown on Figure 4-4, in 2025, single family residential represents most of the total demand at 70 percent. Multiple family homes and commercial uses each total about 9 percent of total demand. Other uses, including industrial and dedicated landscape irrigation, represent a combined 12 percent of total demand. Water demand in the SBUA peaked in the early 2000s and has decreased since then. The decline in total water demand in part reflects a sustained water conservation response to drought achieved through increased public outreach. 4,2,4 CURRENT WATER USE
Currently in the SBUA, water use is dominated by single family residential connections (3,834 AF). Peak water use months in 2025 for all retailers were June through September, averaging 302 AF, 295 AF, and 30 AF for Hollister, Sunnyslope, and SJB respectively. These are the dry months with the least amount of precipitation, explaining the increase in water use. In contrast, the wettest months (December through March) had the least amount of water use, averaging 182 AF, 139 AF, and 19 AF for Hollister, Sunnyslope,
RIMMAMMEUMEUMEMEWARMAMMEURREUMETAMARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEURREM San Benito Urban Areas UWMP 2025
and SJB respectively. Water use in the winter months ranged from 40 percent to 60 percent of the summer months for each retailer. Beginning in April, the proportion of water use for landscape irrigation increased, while the proportions of both single and multi -family residential water use decreased; this trend reversed in November with a greater proportion of water used by residential.
4.2.5 PROJECTED WATER USE
Tables 4-2 Hollister Retail, 4-2 Sunnyslope Retail, and 4-2 SJB Retail provide projections for water service connections and deliveries in five-year intervals between 2025 and 2045, for Hollister, Sunnyslope, and SJB respectively. Table 4-2 W shows the total projected use for the SBUA including the three retailers and an additional 200 AFY that the District currently provides to other M&I users in the area. This volume is not expected to increase over time as the District has no plans to add new M&I customers in the area.
4.2.5.1 GENERAL GUIDANCE ON PROJECTIONS
The 2008 HUA Water and Wastewater Master Plan, and the 2017 and 2023 updates, have calculated buildout water demand based on the land use planning data from the adopted General Plans for the City and San Benito County (HDR 2008). These buildout conditions also have been used in the GSP to simulate future growth out to 2068 (Todd 2021). Total buildout demand for the SBUA as calculated by the 2008 Water and Wastewater Master Plan was projected to be 18,501 AFY for the SBUA (10,994 AFY for Hollister, 6,007 AFY for Sunnyslope, and 1,500 AFY for other users). For the purposes of the UWMP, the increase in water demand must be projected to 2045 in 5 -year increments. While the 2008 Master Plan buildout estimate provides a maximum development scenario, additional information is needed for accurate projections of short term growth.
The 2023 update of the SBUA Water and Master Plan projected water demand through 2045. A key change in the recent demands is the addition of SJB, reflecting the expansion from the HUA to the SBUA, which has now encompassed SJB since the 2021 MOU. The second significant change is that the projected annual population growth has decreased from 4 percent to 3.5 percent based on regional and local planning documents that predict a slower growth rate.
The 2023 Water and Wastewater Master Plan estimates of the projected annual water demand is approximately 12,500 AFY by 2045. However, this includes projected growth from 2020-2025 that has not occurred. For purposes of this UWMP, future use assumes the expected increased growth from 2025- 2045, which is added to actual 2025 water demand. These values represent potable water uses; non - potable water uses are not projected to increase.

4.2.5.2 WATER -USE PROJECTIONS BY SECTOR
To project future demand, the expected water demand increases for each five-year period from the Master Plan Update are shown by sector in Table 4-A. As shown in Table 4-B, the actual 2025 deliveries were used and the projected additions (from the 2023 Water and Wastewater Master Plan) were added to the actual deliveries. The total water use in 2045 is consistent with the previous UWMP that had estimated total water demand at 10,757 AFY in 2040.

These water demand estimates apply per unit demands based on historical consumption. Water conservation measures were considered; however, because the demands were based on historical consumption, additional conservation was not included in the demand forecasts. The water demand for new developments will likely be lower than historical demand due to improved plumbing codes, active water conservation programs, and drought tolerant landscape.
Total water demand is expected to increase to a total of 11,587 AFY by 2045, including recycled water and deliveries to users outside of the retailers' service areas. Tables 4-2 Hollister Retail, 4-2 Sunnyslope Retail, and 4-2 SJB Retail provide projections for water service connections and deliveries in five-year intervals between 2025 and 2045, for Hollister, Sunnyslope, and SJB respectively. The estimated water loss for the associated demand is included based on their current documented water loss percentage. The SBUA increases were divided among the retailers based on the current volumes. Because SJB currently has relatively limited development activity in process compared to other areas within the SBUA, the SJB projections were evaluated independently against the City's current planning assumptions and anticipated development pipeline. The increase for SJB was capped at their forecasted increased growth in their 2020 Water Master Plan 76 AFY (AKEL 2020).
Table 4-2 W shows the expected volume of raw water the District will deliver to SBUA Water Treatment Plans (WTPs). Losses occur within the District's CVP conveyance and storage system (e.g., from evaporation and seepage).
4.2.5.3 STANDARDS, CODE, ORDINANCES, AND PLANS
In accordance with Water Code Section 10631(d)(4) water use projects shall account for the water savings estimated to result from adopted codes, standards, ordinances, or transport and land use plans identified by the urban water supplier.
Water conservation is encouraged in the SBUA through a variety of programs, which are discussed in detail in Section 9. To meet the future water use per capita demand targets, Hollister, Sunnyslope, SJB, the District, and the WRA, through their water conservation coordinator, plan to focus their efforts on several demand management measures (DMMs). These specific DMMs represent opportunities for maximum water savings, based on local experience during recent droughts (2014-2016 and 2021-2023). The DMMs that will continue to save water include state level programs:
1. Model Water Efficient Landscape Ordinance (effective December 1, 2015) —The revised ordinance is projected to reduce typical residential landscape demands by about 20 percent from demands estimated using the prior ordinance provisions. Commercial landscapes may reduce water demand by about 35 percent over the prior ordinance.
2. California Energy Commission Title 20 appliance standards for toilets, urinals, faucets, and showerheads—The appliance standards determine what can be sold in California and therefore will affect both new construction and replacement fixtures in existing homes.
RIMMARMARMARMAMMETEMEWARMAMMEWARMAMMETEMEWARMAMMEWARMAMMETEMEUMEMEWARMARMAMMETEMEUMEMEWARMARMAMMETEMEUMEMEWARMARMAMMETEMEWARMAMMEURREUMEM San Benito Urban Areas UWMP 2025
3. CALGreen Building Code — The CALGreen Building Code requires residential and non-residential water efficiency and conservation measures for new buildings and structures that will reduce the overall potable water use inside each building and structure by 20 percent. The 20 percent water savings can be achieved in one of the following ways: (1) installation of plumbing fixtures and fittings that meet the 20 percent reduced flow rate specified in the CAL Green Code, or (2) by demonstrating a 20 percent reduction in water use from the building "water use baseline." The practical representation of the savings in unit water demands from this code would be to reduce indoor baseline unit demands for recently constructed residential units downward by 2 to 5 percent, although this may be redundant with any reduction already represented by the Title 20 appliance standards.
In addition, several local programs already in place may reduce future water demand:
• Retail conservation pricing — "Conservation pricing" provides incentives to customers to reduce average or peak use, or both. All water rates and charges for Hollister, Sunnyslope, SJB, and the District are established through ordinance by the appropriate governing body. Currently, Hollister's, Sunnyslope's, and SJB's rate structures for water service are increasing block structures for residential customers. Adjusting the rates or adding additional blocks for water rates may continue to improve water conservation.
• Public information programs — One of the cornerstones of an effective water conservation program is effective public outreach and education. Public information and outreach —which convey the need for efficient water use and show how customers can reduce water use —supports all other elements of the program. Public outreach promotes water conservation in general, by informing customers of the needs, benefits, and methods of conserving water. Outreach can also foster understanding regarding how water conservation fits into the overall water management for the SBUA. Current public outreach is focused on schools and students with classroom presentations promoting efficient water use and supplementation of presentations with grade level -appropriate education materials. Presentations are also given to local community groups and service organizations. While the effect of public outreach is unquantifiable, its qualitative effect on water conservation is considered very important. • Rebates — WRA continues to provide a variety of rebate and retrofit programs that have successfully reduced water demand. These programs currently include incentives for replacement or removal of water softeners, efficient landscape hardware, high efficiency washers, and low flow toilets. The District is also considering policies on new developments to encourage water conservation.
• Landscape— This DMM applies to non-residential accounts with dedicated irrigation meters and to commercial, industrial, and institutional (CII) accounts with mixed -use meters. Hollister, Sunnyslope, and SJB continue to implement landscape audit and incentive programs, and these programs can be expanded to account for more water savings. In addition, the WRA has offered landscape efficiency programs over the past two years to encourage water conservation for large landscape and residential customers. Several DMMs are targeted to reducing water waste and increasing water efficiency. The turf removal program encourages irrigators to replace their high

water demand turf with water efficient landscaping. The program, advertised in both English and Spanish, has been very successful in reducing water demand during the recent drought.
A complete list of the DMMs that will be employed by the SBUA and the estimated water reductions resulting from their implementation are presented in Section 9.
4.2.5.4 RETAIL ONLY
Additional future reductions from codes, ordinances, and plans are not considered "passive savings" and were not considered in future water projects (as recorded in Table 4-3 Retail). The SBUA is committed to water conversion but does not include these savings in the demand forecast. The policies and programs implemented in the SBUA to reduce demand are discussed in detail in Sections 8 and 9.
4.2.5.5 LOWER INCOME HOUSEHOLDS
State legislation (SB 1087 and Government Code section 65589.7), effective January 1, 2006, specifies that local water agencies and sewer districts must grant priority for service hook-ups to projects that help meet the community's fair housing needs to lower income households. "Lower income households" are defined as households with an income below 80 percent of the area median income, adjusted for family size. To assist with city planning in addressing this legislation, lower -income household water use is included in water -use projections as reported in Table 4-3 Retail.
4.2.5.6 CLIMATE CHANGE CONSIDERATIONS
Climate change can affect projected water demand. The climate change vulnerability assessment, available from the UWMP 2025 guidebook, was performed for the SBUA. Water use varies by more than 50 percent seasonally, indicating that water demand is relatively elastic (likely reflecting summer landscape uses) and suggesting that water demand has potential to increase. Climate change is likely to increase temperatures and ET and may also increase the duration of high temperature/ET periods ("heat waves"). This would increase water demand for landscape irrigation and other residential uses, with particular ramifications for summer months. Public outreach will be critical to reduce demand in the high- water use summer months. The WRA already has programs to encourage drought tolerant landscaping, improve efficient irrigation practices, and reduce water waste, and these programs have and will continue to reduce potential impacts from climate change.
4.3 DISTRIBUTION SYSTEM WATER LOSSES
4.3.1 PREVIOUS FIVE YEARS DISTRIBUTION SYSTEM LOSSES
Water losses for Hollister and Sunnyslope were calculated using the required methodology and audit tool developed by AWWA ( www.awwa.org/resources-tools/water-knowledge/water-loss-control.aspx) . The DWR requires reporting of losses for retailers for each of the five years preceding this plan update in accordance with Water Code Section 10631(d)(3). This is reported by calendar year. Reported losses to
RIMMAMMUMMUMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARMUM San Benito Urban Areas UWMP 2025
DWR by year from 2021 through 2025 are shown in Table 4-5 Hollister Retail and 4-5 Sunnyslope Retail for Hollister and Sunnyslope, respectively. The AWWA audit results for Hollister and Sunnyslope are included in Appendix C. It should be noted that SJB is not required to and currently does not conduct formal, stand-alone AWWA water loss audits. However, system usage and production are tracked as part of their routine operations and reporting. The AWWA tool uses the total water supply and deliveries by agency to estimate the total water loss. The tool also breaks out apparent water losses (unmetered water or inaccurate meter readings) and real water losses (water leaving the system through leaks, or other physical issues).
Since 2021, reported water losses in Sunnyslope averaged 6.3 percent (51.5 MG/Yr), similar to the period 2016 to 2020. The agency attributes this low loss to its program to replace aging meters. Hollister is currently preparing their water audits for CY 2024 and 2025, and data only from 2021 to 2023 are available. During that period, Hollister reported an average percent water loss of 9.6 percent (106 MG/Yr), ranging from 6.8 to 11.2 percent. SBJ water loss is not audited.
Losses associated within the CVP storage and distribution system are included as raw water losses for the District. Losses are associated with evaporation and seepage as a result of storage in an open reservoir. It is estimated that water losses are about 10 percent in normal years for the CVP storage and distribution system operated by the District.
4.302 PROGRESS TOWARD MEETING THE WATER LOSS PERFORMANCE STANDARD In accordance with Water Code Section 10631(d)(3)(C) Hollister and Sunnyslope have assessed their progress towards the 2028 Water Loss Standard as reported in Table 4-6 R. SJB does not have a 2028 Water Loss Standard, due to its small size.
Hollister has decreased its large number of unmetered water uses including line flushing for sampling, fire flows, construction uses, and other unmeasured and unclassified uses and losses. In the AWWA tool for Hollister, the default ratio of apparent and real losses is used due to lack of data. Hollister estimates that most of its water losses are due to the apparent water loss of unmetered activities. To address this amount of loss, Hollister has a rigorous meter replacement program and is making continuous efforts to identify water losses. The decrease in water losses indicates that the program is already working to reduce excess losses.
The water loss standard for Sunnyslope was set at its baseline water loss, recognizing their already low water loss percentage.

NOTES: Hollister based on 2023 audit
Water agencies must demonstrate compliance with their established water use target for the year 2020 as per Water Code Section 10608.16(a). Water use targets are calculated separately for Hollister and Sunnyslope and the associated information is provided by agency in the WUE portal to allow for each agency to have local control. SJB is a small retailer and previously has not submitted an UWMP. They are now included in the SBUA UWMP as they are part of regional water system supply and demand. Because SJB was not included in the 2020 UWMP, they do not have 2020 Targets.
Compliance is verified by DWR's review of the SB X7-7 Verification Form submitted with an agency's 2020 UWMP.
The goal of this section is for Hollister and Sunnyslope to report on their progress toward meeting their urban water -use targets in pursuit to Water Code Section 10608.40. Discussed in detail in Section 9, these water use targets are based on their past population and water use and set a reasonable per capita demand that each retailer has been able to meet through a variety of demand management measures.
5.1 REPORTING REQUIREMENTS FOR WHOLESALE SUPPLIERS
According to Water Code Section 10608.36, urban wholesale water suppliers shall include an assessment of their present and proposed future efforts to help achieve the required water use reductions. While calculations are not required, Sections 8 and 9 describe the District's policies and programs that will help Hollister and Sunnyslope achieve their 2020 Targets.
5.2 REPORTING REQUIREMENTS FOR RETAIL SUPPLIERS
For each agency, Table 5-1 R compares the 2020 Target per capita and the Actual 2020 GPCD and whether the supplier achieved Target Reduction for 2020. Hollister and Sunnyslope not only met but exceeded their respective 2020 goals (119 gpcd and 143 gpcd). The actual 2020 per capita daily water use was 114 gpcd and 119 gpcd, for Hollister and Sunnyslope, respectively. As stated in the previous section, SJB was not included in the 2020 UWMP and therefore does not have 2020 Targets.
Table 5-1 Hollister and Table 5-1 Sunnyslope summarize progress toward SB X7-7 2020 Target for Hollister and Sunnyslope. SJB was not included in the 2020 UWMP and they do not have 2020 Targets.

NOTES: Sunnyslope
For this section, each normal -year water supply was assessed to provide necessary information for reliability and risk assessments. This information also supports analysis of water supplies in non -normal years, as discussed in Section 7. This section first provides an overview of all water supplies available to SBUA with succinct descriptions of considerations that affect the reliability of each water supply. This is followed by detailed analysis of each water supply source and its use. Energy use associated with water supply also is described. Note that Section 6 tables are numbered as required by DWR but are not discussed in numerical order.
6.1 WATER SUPPLY ANALYSIS OVERVIEW
The SBUA relied historically on the North San Benito Groundwater Basin (Figure 6-1) for its municipal water supply. Since 2003 and development of water treatment facilities, CVP water imported by the District has been available for direct urban use. In addition, recycled water also has been developed for non -potable use. Tables 6-8 Hollister Retail, 6-8 Sunnyslope Retail, and 6-8 SJB Retail, respectively, document the current (2025) water supply by source for Hollister, Sunnyslope, and SJB. The projected water supply by source from 2030 through 2045 is documented in Tables 6-9 Hollister Retail, 6-9 Sunnyslope Retail, and 6-9 SRI Retail for Hollister, Sunnyslope and SJB, respectively. Figures 6-2 through 6-5 are histograms illustrating the historical and current supply by source for each retailer and the entire SBUA.
6.1.1 SPECIFIC ANALYSIS APPLICABLE TO ALL WATER SUPPLY SOURCES Water supply sources for SBUA include imported water from the Central Valley Project (CVP) and local groundwater for potable water uses, and a small volume of non -potable recycled water for landscape irrigation. Each of these water supplies is analyzed in detail in Section 6.2, including physical setting/conditions, management, availability and use, projected use, and future projects. As described in Section 6.2, SBUA does not directly use local surface water, stormwater, or desalinated water. Use of water exchanges and transfers is described.
6.1.2 SPECIAL CONSIDERATIONS
SBUA water supply sources are used conjunctively, such that water supplies, each with its own characteristics, are directed to respective best uses insofar as possible. Each SBUA supply has specific conditions that may affect current or future supply characterization. CVP water supplies are relatively high quality, and with water treatment, can be provided directly toward potable municipal uses. CVP water supplies are based on contractual allocations, and during below normal, dry, and critically dry years, the allocations may be reduced below the contract amount. Groundwater supply has lower quality. However, it is a shared resource among municipal, agricultural, and rural users that is broadly available across the North San Benito Basin and provides important storage during drought. North San Benito groundwater is sustainable, given continuing local management and availability of local and imported water for recharge.
SitaRMIRMUNMEMMUNMEMMUNMEMMMUMMUMMUMMUMMUMMUNMMUMMUMMUMMUMMUMMUMMUMMUMMUMMUNMEMMEMMUNMMUMMUMMUNMEMMUMMUMMURVAMMUNMEMMUMENNMEM San Benito Urban Areas UWMP 2025
Recycled water is highly reliable, but relatively poor quality and requirements for treatment limit its use to non -potable irrigation demands. These conditions and impacts on the water supply sources are discussed in further detail in Section 7.
6.1.2.1 CLIMATE CHANGE EFFECTS
Climate change is likely to affect water supply as well as demand (see Section 4.2.5.6). The most significant impact will be on the availability of imported water. As the climate warms, snowpack is expected to decrease in average annual amount and seasonal duration and to become more variable from year to year. With loss of reliable seasonal storage, CVP allocations will decrease and become more variable. In addition, CVP supply relies in part on the Delta, which is a climate -sensitive habitat where environmental requirements may also reduce CVP allocation. As discussed in Section 6.2.1, there are limited projections for future CVP supplies. Cal Sim III, the latest forecast, has been used to evaluate State Water Project (SWP) and forecasts slightly reduced allocations in the future due in part to climate change, although similar to what has been experienced over the past 20 years. Because of the CVP M&I Water Shortage Policy and the District's demonstrated Public Health and Safety need of 2,766 AF, a minimal municipal allocation is assumed to be available, amount to 33.5 percent of the District's M&I contract amount.
6.1.2.2 REGULATORY CONDITIONS AND PROJECT DEVELOPMENT
Future water supply availability and reliability may also be affected by emerging regulatory conditions and planned future projects. Most importantly, any modifications to the Bay -Delta Water Quality Control Plan to reduce reliance on the Delta could impact availability of CVP water, which is imported by the District through the Sacramento -San Joaquin River Delta. Planned water projects such as Sites Reservoir and B.F.
Sisk are intended to increase CVP supply and reliability. 6,1,2,3 LOCALLY APPLICABLE CRITERIA
The North San Benito Basin groundwater resource is actively managed by the District and Valley Water Groundwater Sustainability Agencies (GSAs) The GSAs have developed and adopted the North San Benito Basin Groundwater Sustainability Plan (GSP), which is being implemented actively consistent with Sustainable Groundwater Management Act (SGMA). The GSP defines sustainability criteria for groundwater levels, storage, quality, subsidence and interconnected surface water. These locally -defined criteria guide groundwater management actions and projects. Progress is regularly reported and periodically evaluated.
6.1.2.4 THE SBUA COORDINATION
The SBUA UWMP, the Master Plan, and the WRA are all efforts that represent ongoing collaboration among the District, Hollister, Sunnyslope, and SJB in providing a secure and stable water supply to the region. Data are shared between all entities. This collaboration increases reliability of available water supplies.

6.2 WATER SUPPLY CHARACTERIZATION
6.2.1 IMPORTED WATER
The CVP is a Federal water system operated by the U.S. Bureau of Reclamation (USBR) and created to:
protect the Central Valley from water shortages and floods, improve navigation on the Sacramento River, provide supplies of municipal and industrial water, enhance water quality, generate electric power, conserve fish and wildlife, and create opportunities for recreation. The CVP consists of 20 dams and reservoirs, 11 power plants, and 500 miles of major canals, conduits, and tunnels. About nine million AFY of water are managed by the CVP and about seven million AFY of water for agricultural, urban, and wildlife uses are delivered annually. An average of five million AFY of CVP water is provided to farms to irrigate about three million acres of land and about 600,000 AFY of water is provided for municipal and industrial uses. About 800,000 AFY are provided for fish and wildlife habitats and 410,000 AFY to State and Federal wildlife refuges and wetlands, pursuant to the Central Valley Project Improvement Act (CVPIA). Finally, the CVP generates 5.6 billion kilowatt hours of electricity annually (Mintier Harnish 2009).
The San Benito County Water District has a contract for a maximum of 8,250 AFY of M&I water and 35,550 AFY of agricultural water. The contract provides the provision to convert any, or all, of the agricultural entitlement to increase the 8,250 AFY M&I entitlement when the demand for M&I water grows beyond 8,250 AFY. Imported water is delivered to agricultural, municipal, and industrial customers in Zone 6 through 12 subsystems containing approximately 120 miles of pressurized pipeline laterals (SBCWD 2011).
In 2021, the District converted its CVP contract from a water service contract to a permanent repayment contract pursuant to the Water Infrastructure Improvements for the Nation Act, and the contract no longer has an expiration date. At that time, the District paid off its share of the capital costs associated with the "in -basin" CVP facilities, which are those facilities located in the Central Valley that are needed to produce and convey CVP water to the District. The District will continue to pay for its share of "out -of - basin" capital costs, which are associated with the federal facilities that convey CVP water from San Luis Reservoir to San Benito County, according to the repayment terms negotiated in the 2007 contract amendment.
The District distributes CVP water to both agricultural and M&I customers in Zone 6. Hollister and Sunnyslope purchase CVP water directly from the District as they are the primary M&I CVP customers. SJB is expected to begin receiving treated CVP water by the end of 2027/beginning of 2028. Other M&I uses of CVP water include urban irrigation, golf courses, and potable supply for the Stonegate community.
Actual CVP deliveries are modified on an annual basis by USBR, reflecting hydrologic conditions (e.g., drought), reservoir storage, and the environmental status of the Sacramento -San Joaquin Delta. In USBR water year 2025, the allocation for M&I users was 80 percent of historical use while agricultural users received 55 percent of contract amounts. Reductions in recent years are primarily the result of the less than average precipitation and increasingly stringent regulatory requirements in the Delta (Todd 2025).
RIMMAMMEUMEUMEMEWARMAMMEURREUMETAMARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEURREM San Benito Urban Areas UWMP 2025
WATER SUPPLY FACMTIES
Water treatment for potable M&I supplies within the SBUA is provided by the Lessalt WTP and West Hills WTP. The Lessalt WTP, placed into operation in January 2003, is designed to treat imported CVP water using microfiltration and chlorine disinfection (HDR 2008a). In 2015, the plant was upgraded with granulated activated carbon filtration to remove organic materials and thereby reduce trihalomethanes (THMs) in water. In addition, further treatment to remove iron and manganese was added. Treated water is distributed to Hollister and Sunnyslope customers. The Lessalt WTP was constructed to provide CVP as a direct source of M&I water and to improve delivered water quality by supplementing existing groundwater with higher quality surface water. The Lessalt WTP was completed in 2002 with a nominal design capacity of 3 million gallons per day (MGD). Because of hydraulic constraints, process limitations, and reductions in CVP water availability, the WTP operated initially at an average rate less than 1.6 MGD.
A WTP expansion completed in April 2015 increased the operational capacity of Lessalt to 2.0 MGD, which extends the capacity of the WTP to an annual total of 2,240 AFY.
West Hills WTP is the second surface water treatment plant to treat CVP imports and allows delivery of high quality CVP water to urban areas (including disadvantaged communities) currently not served by the Lessalt WTP. West Hills came online in August 2017, with a long-term operational capacity of 4.0 MGD, or 4,480 AFY. Additional treatment capacity has been added to West Hills as part of the Accelerated Drought Response Project (ADRoP), but this increased capacity will not be used to serve urban customers directly.
As of 2026, design is proceeding for a new water transmission pipeline from the West Hills WTP along Highway 156 to the SJB water system.. Once operational, this project is expected to provide additional capacity for the SJB system and allow SJB to blend CVP water with groundwater supplies, improving both supply reliability and water quality.
The total treatment capacity of M&I CVP water available to the San Benito Urban Area is currently 6,720 AFY.
The District manages San Justo Reservoir as storage for imported CVP water. In times of full allocation, the District is able to purchase additional water to keep as a reserve for future dry years. The District's planned reserve is 5,000 AF, plus additional CVP transfers and exchanges, which would be sufficient to provide supply (in addition to groundwater) for up to five years with preferred blending of imported water and groundwater. Based on future demand and supply calculations, this reserve may only be needed when CVP allocations for M&I uses are at the lowest allocations, namely 50 percent, which is identified by USBR for health and safety purposes (USBR 2017).
2025 ACTUAL USE OF SUPPLY
Total CVP imported water delivery for 2025 was 4,104 AFY to the SBUA. This includes both West Hills and Lessalt Treatment Plant deliveries to both Sunnyslope and Hollister. The two agencies work closely together to ensure adequate supply. In the past, the individual deliveries from Lessalt Treatment Plant were not metered but assumed to serve Hollister and Sunnyslope equally. With the addition of West Hills, the flow from the treatment plants to the agencies is monitored, although water can flow between the
RIMMAMMEUMEUMEMEWARMAMMEURREUMETAMARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEURREM San Benito Urban Areas UWMP 2025
agencies via interties. While the intertie flow is also monitored, the flow from both plants is combined and only total volumes of treated water are available. CVP deliveries represented 61 percent of total supply in 2025, an increase over the five-year average of 50 percent of total supply. The decreased utilization of CVP imports is due in part to limited CVP allocations and temporary WTP closures to address engineering issues. The percent of total supply from imported water is expected to increase as treatment capacity has expanded and there is no planned downtime at the WTPs.
WATER YEAR TYPES
Hydrologic conditions play a large role in the availability of CVP imports. The percent of the CVP contract allocated to the District is based on available supplies. While the total contract is for a maximum of 8,250 AFY of municipal and industrial (M&I), the District has only received 100 percent allocation in four out of the last fifteen years. The allocation varies from year to year based on the hydrologic conditions of the larger CVP system. Since 2006, the M&I allocation has ranged from 0 percent (public health and safety only) in dry years to 100 percent in wet years, with a 10 -year average of 75 percent (Todd 2025).
PROJECTIONS
Future CVP supply and contract allocations are estimated by recent allocations observed during severe droughts and wet years (2007-2025). The GSP relied on Cal Sim II, a DWR tool used to simulate California SWP/ CVP operations. For the GSP simulations, the average allocation was 74 percent of the contract amount. Under normal conditions, the Cal Sim II simulations indicate that expected long-term allocations would average 82 percent of the M&I contract. This projection is more optimistic than current allocations and therefore has not been applied in this UWMP.
Since 2007, when court decisions changed how allocations are evaluated, allocations varied widely from 25 percent in dry years to full allocation in wet years. Over this time, allocations have averaged 62 percent.
Table 6-A shows the average allocation for the SBUA based on the water year type of the Sacramento River system, which supplies much of the CVP system.

Future CVP supply availability is based on recent allocations and discussed in more detail in Section 7.
RIMMARMARMARMAMMETEMEWARMAMMEWARMAMMETEMEWARMAMMEWARMAMMETEMEUMEMEWARMARMAMMETEMEUMEMEWARMARMAMMETEMEUMEMEWARMARMAMMETEMEWARMAMMEURREUMEM San Benito Urban Areas UWMP 2025
Tables 6-9 Hollister Retail, Table 6-9 Sunnyslope Retail, Table 6-9 SJB Retail, and Table 6-9 W show the projected future supply for the four agencies. The future supply to the District is the projected average CVP projections. In turn, the CVP supply available to the three agencies is the District's supply less other users and system losses, 5,388 AFY (see Table 6-9 W). The SBUA now has a treatment capacity of 6,720 AFY, which will allow the SBUA to fully use the expected allocation. It is assumed that Hollister and Sunnyslope will equally share the CVP supply to the SBUA and that SJB will receive up to 80 percent of their supply when available. Hollister is expected to continue its municipal supply of recycled water at 80 AFY. All three retailers will rely on groundwater for the remainder of the potable demand.
As discussed in the groundwater section, the SBUA mostly overlies the Hollister Management Area (MA) with a portion in San Juan MA. The sustainable yield for M&I uses in the Hollister and San Juan MA as defined in the GSP through future simulations is approximately 6,250 AFY (5,600 AFY and 650 AFY for Hollister MA and San Juan MA respectively).
This volume could be expanded during drought conditions as needed. In 2040, the SBUA plans to use groundwater as a supplemental supply during normal, single dry, and multiple dry years. Under normal conditions, the total groundwater pumping from the retailers (taking into account expected losses and other M&I deliveries) is expected to total 6,237 AFY, slightly less than the simulated Hollister MA sustainable yield.
It is expected that CVP imports will continue to be the most desirable water source for the SBUA in the future and that additional demand will be met with local groundwater blended with imported supplies.
Blending is required to meet the water quality objectives detailed in the Master Plan and Water Supply and Treatment Agreement. The SBUA plans to maximize CVP imports, understanding the limitations in reliability and financial constraints. The preferred distribution of 80 percent imported water and 20 percent groundwater is a matter of preference and may be relaxed during short term droughts.
6.2.2 GROUNDWATER
Groundwater is a major source of supply for Hollister, Sunnyslope, and SJB. The three retailers pump directly from wells located in the SBUA. The District, formed by a special act of the State, has regional responsibility and authority to manage groundwater. As part of its management activities, the District provides recharge to the basin, explores expanded groundwater banking, monitors water levels and water quality, and reports annually on groundwater conditions in the basin.
6.2.2.1 BASIN DESCRIPTION
LOCATION
The SBUA overlies the North San Benito Groundwater Basin, designated as DWR Basin No. 3-3.05, shown on Figure 6-1 (DWR 2021a). The basin covers 200 square miles of the Pajaro River watershed and is drained by its tributaries, most notably the San Benito River. The San Benito River, intermittent in some parts of the basin, runs through the southern portion of the basin before reaching the Pajaro River. The
RIMMAMMEUMEUMEMEWARMAMMEURREUMETAMARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEURREM San Benito Urban Areas UWMP 2025
San Benito River, when flowing, is a recharging stream along much of its channel, but groundwater contributes some base flow upstream of its confluence with the Pajaro River. The Hernandez Reservoir, located upstream of the basin on the San Benito River, is operated to enhance flow in the river and recharge the groundwater basin.
GEOLOGY
The North San Benito Groundwater Basin lies within the Coast Ranges of California, which are a series of elongated ranges and valleys with a predominantly northwesterly trend. The Hollister Valley's origin and shape has been controlled by folding and faulting of basement rocks in the area, resulting in low-lying areas that have been infilled with unconsolidated to poorly consolidated alluvium of Tertiary and Quaternary age. The Quaternary alluvial deposits compose the valley floor and generally define the groundwater basin (California Geologic Survey 2002, Todd 2004). Numerous investigators have recognized the difficulty in describing the subsurface stratigraphy of the basin, due, in part, to sparse geophysical log data and a lack of distinctive textures and composition among the sedimentary units (Kilburn 1972, Faye 1974 and 1976, Luhdorff and Scalmanini 1991).
Major geologic faults, including the San Andreas and Calaveras, trend northwestward through the area.
Most notably, the Calaveras fault is active and cuts through the basin, trending north-northwest from Hollister to the Pajaro River at San Felipe Lake, and separating the northern valley into two distinct geologic units at depth. The fault is perceived to impact groundwater flow locally, perhaps due to the presence of low permeability rock fragments and blocks displaced upward and adjacent to more permeable alluvial material along the fault zone (Todd 2004).
The Quaternary -age alluvium contains the main aquifers in the groundwater basin. The aquifers are the coarse -grain layers of sands and gravels with interbedded layers of silts and clays. The geometry of the basin suggests that basin -fill units were deposited in alluvial fan and fluvial environments from a variety of source rocks and directions. These deposits interfinger in the subsurface, making the differentiation of discrete aquifer packages difficult on a regional basis. This also results in variable aquifer properties across the basin. Previous investigators indicate wide variability in aquifer transmissivities (Luhdorff and Scalmanini 1991, Faye 1974). Although poorly defined, regional variations in permeability likely create preferential pathways for groundwater, especially in paleo-channel deposits, which may exist beneath current major stream courses or elsewhere in the basin (Todd 2004).
SUBAREAS
Figure 6-1 shows the four management areas delineated as part of the GSP: Bolsa, San Juan, Hollister, and Southern. This definition of subbasins is maintained in this report, supporting consistent reporting of groundwater conditions.
The SBUA overlies part of the Hollister and San Juan MAs. In water year 2025, all of Hollister and Sunnyslope's pumping was located in the Hollister MA and all of SJB's pumping was located in the San Juan MA.

GROUNDWATER LEVELS AND FLOW
In general, groundwater in the basin flows from the southeast and eastern portions of the basin toward the western and northwestern portions of the basin to the Pajaro River. However, general flow directions have been reversed in the Bolsa subbasin due to groundwater pumping; groundwater in the Bolsa subbasin near the Pajaro River flows southeast toward lower water levels.
Groundwater levels have been recorded in the basin since at least 1913 by various agencies including USBR, DWR, Pacheco Pass Water District, San Benito County, University of California Cooperative Extension, and the United States Geological Survey (USGS) (Clark 1924, Kilburn 1972, Farrar 1981, Creegan & D'Angelo 1990). The District monitors water levels in approximately 80 to 100 wells on a semiannual and, more recently, a quarterly basis and reports the data as needed to the SGMA portal. Water levels and trends are presented in the District annual reports (e.g., Todd 2025). Groundwater generally occurs under unconfined and confined conditions. Surficial clay deposits, especially in the Bolsa and San Juan areas, create confining layers. These layers have resulted in local artesian conditions wherein groundwater levels in wells have risen to the surface.
Figure 6-6 illustrates long term changes in groundwater levels in the basin. Water elevations in key wells from the Hollister management area (Figure 4-5 from GSP) are shown on the map in Figure 6-6.
GROUNDWATER RECHARGE
The District owns and operates two reservoirs along the San Benito River. Hernandez Reservoir (capacity 17,200 AF) is located on the upper San Benito River in southern San Benito County. Paicines Reservoir (capacity 2,870 AF) is an offstream reservoir between the San Benito River and Tres Pinos Creek. It is filled by water diverted from the San Benito River, with some of the diversions consisting of natural runoff and some consisting of water released from Hernandez Reservoir. Water stored in the two reservoirs is released for percolation in Tres Pinos Creek and the San Benito River to augment groundwater recharge during the dry season. Since 1996, releases from Hernandez have ranged between 0 AFY and 32,450 AFY, generally reflecting variations in inflow. The total releases from Paicines Reservoir range from 0 AFY to 6,139 AFY (Todd 2025).
In the past, the District has purchased and percolated additional CVP imported water for groundwater management. This program began in 1988, and CVP percolation peaked in 1997 at 11,087 AFY. Managed CVP percolation volumes were reduced following 1997 in response to successful recovery of the groundwater basin from overdraft. In recent years, the District has restarted the CVP recharge program at off -stream ponds. In water year 2025, 1,667 AFY of imported water was recharged in the groundwater basin (Todd 2025).
Hollister and Sunnyslope percolate treated wastewater discharge to the groundwater basin. The City of Hollister Domestic Wastewater Treatment Plant (DWWTP) represents the major portion, amounting to 3,131 AF in water year 2025. Wastewater percolation has been decreasing in recent years and is expected to continue to decrease as recycled water use increases. The Sunnyslope treatment plant also percolated wastewater discharge, 167 AF in water year 2025 (Todd 2025). The City of San Juan Bautista does not
RIMMAMMUMMUARMARMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARM San Benito Urban Areas UWMP 2025
percolate wastewater directly to the groundwater basin and instead delivers its wastewater to the DWWTP in Hollister for treatment.
WATER QUALITY
The District conducts semiannual sampling (spring and fall) of more than 24 wells distributed spatially over the basin. In addition, water suppliers with more than six connections, including Hollister, Sunnyslope, and SJB are required to monitor and report water quality to the State Water Resources Control Board Division of Drinking Water (DDW). These data and others are used by the District to monitor and track the status of water quality basin -wide.
A comprehensive water quality database for the District was created in 2004. This database, funded in part by a DWR grant, involved compilation of all available water quality data with the intent of regular update with future data. The first major update occurred as part of the 2007 Annual Groundwater Report.
The database is now regularly updated with readily available local data. A more complete update of the water quality database, including research at local, regional, and state agencies, occurs on a triennial basis.
The database was updated in February 2026, as part of the Annual Groundwater Report for Water Year 2025 (Todd 2026).
The quality of groundwater in the North San Benito Groundwater Basin has been described as highly mineralized and of marginal quality for drinking and agricultural purposes. The mineralized water quality is typical of other relatively small Coast Range groundwater basins but has also been impacted by decades of human -related activities, both agricultural and urban.
A general measure of groundwater quality is total dissolved solids (TDS). For drinking water purposes, TDS concentration of 500 milligrams per liter (mg/L) or less are recommended; however, TDS concentrations up to 1,000 mg/L are acceptable. TDS concentrations are affected by both natural and anthropogenic sources. While concentrations are high (e.g., exceeding 500 mg/L), recent years (2023 through 2025) are characterized by TDS concentrations that are stable or decreasing.
The SBUA agencies blend treated imported CVP water with local groundwater to reduce TDS in Hollister and Sunnyslope's water supplies. If CVP water is available, the objective for M&I delivered water is around 80 percent CVP imports with the remaining 20 percent as groundwater. This blending results in better delivered water supply and sufficient wastewater quality to produce high quality recycled water and meet wastewater discharge requirements with the California Regional Water Quality Control Board (RWQCB).
The blending of groundwater with imported CVP water results in a linkage between groundwater supply and CVP allocations. In dry years, when CVP allocations are low, the volume of groundwater supply used by the SBUA agencies for urban supplies will be limited to maintain the planned blending ratio. The retailers target 60 percent CVP imports with the remaining 40 percent as groundwater in dry years. These blending requirements could be relaxed on a short-term basis in response to drought conditions.

WATER BALANCE AND SUSTAINABLE YIELD
The District prepared a Groundwater Sustainability Plan (GSP) for the North San Benito Groundwater Basin in 2022 and is in the process of preparing a Periodic Evaluation and GSP Amendment. As part of the 2022 GSP, the existing numerical model was expanded and updated to simulate the water budget and groundwater flow. For each Annual Report, the model is updated for the previous water year and the change in storage is calculated. For the GSP amendment, the model will be updated and improved.
Major inflows include deep percolation from rainfall, return flow from urban and agricultural uses, recharge of reclaimed water, stream percolation (both natural and managed through reservoir and CVP releases), and subsurface inflow from adjacent groundwater basins. Most of these inflows are controlled by hydrological conditions and are generally greater in wet years and reduced in dry years.
Major outflows include pumping by agricultural and urban users and subsurface outflow to adjacent basins. Agricultural groundwater pumping is not reliably consistent throughout the basin and is estimated in the model based on land use and reference evaporation. The volume of agricultural pumping in Zone 6 in any given year is dependent on the volume of CVP imports and the amount and distribution of rainfall, as growers often rely on both groundwater and CVP for water supply. Municipal pumping has decreased significantly as the SBUA expanded its ability to treat CVP water and use it directly.
The change in storage calculated by the numerical model for 1975-2025 shows fluctuations due to changes in management and hydrologic conditions. Groundwater storage was at its lowest near the beginning of the simulation because of overdraft during the preceding decades and an intense drought during 1976- 1977. Hollister MA groundwater storage increased significantly when imported water deliveries began in 1988. With decreased groundwater pumping, managed aquifer recharge, and several wet years in the 1990s, groundwater storage increased rapidly and has remained relatively steady since 1998. The recovery of groundwater levels and storage in the Hollister MA provided a buffer for the recent droughts of 2014-2016 and 2021-2022, allowing local groundwater users to pump groundwater without severe declines.
The water budget section of the 2022 GSP estimates a sustainable yield based on expected future pumping. Sustainable yield is defined as the volume of pumping that the basin can sustain without causing undesirable effects. It is not a fixed or inherent natural characteristic of a groundwater basin. Rather, it is influenced by land use activities, importation of water, wastewater and stormwater management methods, and the locations of wells with respect to interconnected streams. The estimate of sustainable yield presented in this section reflects the current status of those variables and evaluates whether there would be a long-term increase or decrease in basin storage if those conditions continued over a 50 -year future period with local hydrology and CVP imports (per CaISim2) corresponding to 1925-1953 and 1982- 2002. The GSP analysis separates out the potential yield of groundwater by user. Based on numerical modeling and analysis detailed in the GSP, the estimated sustainable yield for groundwater for M&I uses in the Hollister MA, where all of the municipal wells for Hollister and Sunnyslope are located, is about 5,600 AFY. SJB pumping occurs in the San Juan MA that has a sustainable yield of 650 AFY. The total
RIMMAMMEUMEUMEMEWARMAMMEURREUMETAMARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEURREM San Benito Urban Areas UWMP 2025
sustainable yield for M&I pumping is 6,250 AFY. As noted above, future use of local groundwater supply may be limited or require treatment due to water quality concerns (Todd 2021). 6,2,2,2 GROUNDWATER MANAGEMENT
The District manages the water resources for all of San Benito County. The District is a California Special District formed in 1953 by the San Benito County Water Conservation and Flood Control Act. The District has jurisdiction throughout San Benito County and has formed three zones of benefit to fund surface water and groundwater management activities. Zone 1 covers the entire county and provides the funding base for certain District administrative expenses. Zone 3 generally covers the San Benito River Valley to the confluence with the Pajaro River, from the Highway 25 Bridge nine miles south of the town of Paicines to San Juan Bautista, plus the Tres Pinos Creek Valley from Paicines to the San Benito River. Zone 3 provides the funding base for operation of Hernandez and Paicines reservoirs and related percolation and groundwater management activities. Zone 6 includes the two MAs (San Juan and Hollister) and provides the funding base for importation and distribution of CVP water and related groundwater management activities (Todd 2010, HDR 2008a). It should be noted that the SBUA includes Zone 6 and additional areas.
SUSTAINABLE GROUNDWATER MANAGEMENT ACT (SGMA)
The 2014 Sustainable Groundwater Management Act (SGMA) requires sustainable groundwater management for designated medium- and high -priority groundwater basins; the North San Benito Groundwater Basin is medium priority. SGMA requires sustainable management of priority groundwater basins and empowers local Groundwater Sustainability Agencies (GSAs) to manage groundwater resources. San Benito County Water District GSA (SBCWD GSA), in partnership with Valley Water (known as Santa Clara Valley Water District prior to 2019) GSA, has developed a Groundwater Sustainability Plan (GSP) for the North San Benito Basin. The North San Benito Basin (Basin) is predominantly in San Benito County with small areas in Santa Clara County. The North San Benito GSP was adopted by the SBCWD and Valley Water GSAs and was submitted to the California Department of Water Resources (DWR) in January 2022. The 2022 GSP provides the basic information, analytical tools, and projects and management actions for continued groundwater management, guided by SGMA and by locally defined sustainability goals, objectives, and metrics. The GSP was approved by DWR in July 2023.
ANNUAL GROUNDWATER REPORT
Each water year, the District oversees the preparation of an Annual Groundwater Report that describes current groundwater conditions in the District and the DWR defined groundwater basin. The report documents water supply sources and use, groundwater levels and storage, and District management activities over the water year (October to September). Recommendations are provided with regard to the future water year imports, groundwater replenishment, groundwater pumping, and groundwater charges. This Annual Report is prepared at the request of the District to meet its information needs and to fulfill statutory reporting requirements including SGMA and the District's Special Act (Todd 2025).

WATER RIGHTS
The North San Benito Groundwater Basin is not an adjudicated basin and groundwater entitlements or rights have not otherwise been defined. The long-term reliability of groundwater supply for the SBUA is not likely to be predicated on water rights but is likely to be defined by the overall state of the groundwater basin.
6,2,2,3 OTHER CONSIDERATIONS
Groundwater resources of the North San Benito Basin are shared among the municipal, agricultural and rural users and managed conjunctively with local and imported water supplies. In the North San Benito Basin, groundwater provides important supply and storage benefits and is sustainable, given continuing local management and availability of imported water for recharge. The long history of collaborative groundwater management —now guided by SGMA—supports water supply reliability.
OVERDRAFT CONDITIONS
While groundwater levels over time have varied in response to precipitation, groundwater pumping, and managed aquifer recharge conditions, the basin is not in overdraft and is managed sustainably.
Water levels are estimated to have been at historical highs prior to 1913 before development of groundwater pumping (Kilburn 1972). In the extreme drought conditions of the late 1970s, water levels in some areas had declined more than 150 feet from the estimated highs (Creegan & D'Angelo 1990).
With the exception of a few areas of persistent water level lows, by 1998 groundwater levels had recovered close to the historical highs as a result of decreased pumping (following CVP importation), increased precipitation, and managed aquifer recharge (Jones & Stokes 1999). During the drought that began in 2021, groundwater levels declined over much of the basin, most notably in agricultural areas of the basin that rely on groundwater. These subbasins sustained four successive years of drought with limited CVP imports. During this time groundwater elevations declined slightly or remained steady in areas of municipal pumping including Hollister East and Tres Pinos subbasins.
Groundwater elevation declines during drought do not constitute overdraft, which is a chronic condition.
The North San Benito Basin is not in overdraft and sufficient storage remains in the basin to accommodate additional dry conditions with limited imported water availability. However, if drought conditions persist, avoidance of significant and unreasonable impacts will require delivery of alternative supplies to sensitive areas or more rigorous water demand management.
6.2.2.4 PAST FIVE YEARS GROUNDWATER PUMPING
Table 6-1 Hollister Retail, Table 6-1 Sunnyslope Retail, and Table 6-1 SJB Retail show the historical pumping of Hollister, Sunnyslope, and SJB respectively. In general, municipal pumping in the area has decreased over time due to increased treatment and use of imported water and water conservation measures (Figure 6-5). Average municipal pumping has declined as CVP treatment capacity has increased.
RIMMAMMUMMUARMARMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARM San Benito Urban Areas UWMP 2025
From 1996 to 2002 (before Lessalt WTP came online) pumping averaged 6,563 AFY. From 2003 to 2016 (with only Lessalt WTP online), pumping averaged 4,580 AFY. Average pumping from 2020 to 2025 is around 2,900 AFY, two thirds of the total pumping pre-CVP imports.
The groundwater basin is a shared resource, and other users (mainly agricultural) rely on groundwater supplies from the same MAs. For the SGMA Annual Report water balance, total current pumping in the Hollister MA is estimated to be around 47,700 AFY (2,500 AFY for M&I uses and 45,000 AFY for Agricultural uses). Municipal pumping has represented up to 15 percent of total pumping in the Hollister MA during the recovery period 1989-2014, reflecting the available CVP deliveries for agricultural users but limited CVP treatment capacity for M&I users. Locations of municipal wells in the SBUA are shown on Figure 6-
6. 2025 ACTUAL USE OF SUPPLY
In 2025, the pumping for Hollister, Sunnyslope, and SJB totaled 2,230 AFY. Hollister and Sunnyslope each pumped about 45 percent, while SJB pumped about 10 percent of the total groundwater used. The interties that connect Hollister and Sunnyslope allow groundwater pumped from either retailer to flow to each other. These two retailers use this connection to ensure that groundwater and CVP water are delivered efficiently to SBUA customers.
WATER YEAR TYPES
Groundwater use varies with water year type but is managed for long-term sustainability. In dry years (drought), the groundwater aquifer serves as an important storage reserve and the use of groundwater increases as CVP imports decrease. In wet years with available imported water supply and increased artificial and natural recharge, groundwater in storage increases.
PROJECTIONS
Groundwater is expected to make up the difference between total SBUA demand and CVP deliveries.
While CVP deliveries are preferred due to better water quality, the allocations are limited especially during drought. Groundwater will be used to make up for any decreased allocations during drought and any increase in growth above the CVP contracted volumes.
6.2.3 SURFACE WATER
While local surface water is not directly used for water supply, it is used as a source of managed recharge to the groundwater aquifer. In most years, local surface water released from the District's Hernandez and Paicines Reservoirs is percolated along the San Benito River and Tres Pinos Creek. Releases of local surface water have been limited typically to percolation upstream of the confluence of San Benito River and Tres Pinos Creek. This has helped maintain groundwater levels without causing shallow groundwater problems and competing for available storage space with the City of Hollister wastewater percolation ponds.

In Water Year 2025, Paicines and Hernandez releases were 355 AFY and 5,394 AFY respectively, representing average hydrologic conditions.
2025 ACTUAL USE OF SUPPLY
There was no direct use of surface water in 2025.
WATER YEAR TYPES
While the volume of releases from the reservoirs, and therefore the recharge to the groundwater basin, varies based on water year conditions, there is no direct use of surface water.
PROJECTIONS
Reservoir releases and the corresponding recharge are expected to remain similar to historical conditions.
There is no projected direct use of surface water.
6.2.4. STORM WATER
Currently, storm water is not diverted for direct beneficial use. However, while some stormwater runs off to the San Benito River, a portion of stormwater runoff enters the City of Hollister's storm water system and treated in the wastewater industrial plant prior to discharge to ponds. The collected storm water serves to increase the volume recharged in the disposal ponds and improves the discharge water quality.
Hollister has developed a stormwater plan, and Best Management Practices (BMPs) were approved in late 2024 as part of the General Plan update to ensure storm water does not pose a threat to surface water quality and is properly routed through the City of Hollister.
6.2.5 WASTEWATER AND RECYCLED WATER OPPORTUNITIES
This section presents a summary of SBUA wastewater collection, treatment, and disposal; current and projected recycled water use; programs to encourage recycled water use; and the SBUA plan for optimizing recycled water use.
6.2.5.1 RECYCLED WATER COORDINATION
In 2004, the City of Hollister, the County, and the District executed a Memorandum of Understanding (MOU) forming a partnership to undertake the development of the Master Plan for the SBUA. The MOU was amended in 2008 to include Sunnyslope. A new MOU with Hollister was completed in 2014 that allowed the District to receive recycled water from the Hollister wastewater treatment plant and make it available to agricultural customers in the area. These parties have undertaken a coordinated effort to plan water supply and wastewater strategies for the SBUA. These strategies include the collection and treatment of wastewater as well as disposal and recycled use, as appropriate.
RIMMAMMUMWARNMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUM San Benito Urban Areas UWMP 2025
Planning for recycled water use has included the preparation of a Recycled Water Feasibility Study prepared by the District in 2005 (RMC 2005) and a subsequent Recycled Water Feasibility Study Update prepared jointly by the District and Hollister (HDR 2008b). The Long Term Wastewater Master Plans (LTWWMPs) were prepared respectively by Hollister and Sunnyslope, and the Master Plan was prepared jointly by Hollister, Sunnyslope, and the District (HDR 2008a). The Master Plan was updated in 2023 with full integration of SJB (HDR 2023).
Recycled water is currently being used for irrigation at one site within the SBUA. While there are no detailed plans to increase recycled water use in the SBUA, additional recycled water is supplied to areas outside of the SBUA for agricultural irrigation (Todd 2020). Increasing recycled water supplies could reduce groundwater pumping in the area, increasing available groundwater supplies for other parties, including the SBUA retailers.
Recycled water is currently available and will become more widely available in the near term. However, neither increased municipal non -potable use nor potable reuse opportunities are targeted currently for implementation because agricultural use is a higher priority.
6.205.2 WASTEWATER COLLECTION, TREATMENT AND DISPOSAL
As indicated on Table 6-2 R, five wastewater treatment plants treat the domestic, commercial, and industrial wastewater flows generated within the SBUA (Figure 6-7). The existing wastewater facilities are owned by two separate agencies: Hollister and Sunnyslope. San Benito County operated Cielo Vista Estates Wastewater Treatment Plant until 2024 when it was decommissioned and replaced with a connection to the Hollister system. SJB historically operated a wastewater facility but, as of mid -2026, is in the final stages of a major wastewater project, which connects SJB sewage to the Hollister Domestic Water Reclamation Facility. The facility descriptions are included below, organized by agency.
Current wastewater collection and treatment volumes for each of the treatment plants are presented on Table 6-3 R. The Hollister Water Reclamation Facility treated 3,425 AF of wastewater in water year 2025.
While most of the treated wastewater was discharged to percolation ponds, 80 AFY of recycled water was used for urban irrigation.
City of Hollister Wastewater Facilities
Hollister owns and operates two wastewater treatment plants (WWTPs); the domestic wastewater treatment plant/water reclamation facility (DWWTP/WRF) and the industrial wastewater treatment plant (IWWTP). The DWWTP/WRF, located on the western edge of the SBUA (Figure 6-7), was built in 1979 to treat Hollister's domestic wastewater. The IWWTP (located west of downtown Hollister) treats seasonal industrial wastewater and storm water from the downtown area. The City of Hollister's collection system consists of gravity pipelines and force mains ranging from 4- to 36 -inches in diameter.
The Hollister DWWTP/WRF began operating in March 1980, was renovated in 1987 to increase capacity, improved in 2002 and 2003 to improve treatment efficiency, and upgraded in 2009 to include the WRF and improve treatment to tertiary levels. Construction of distribution systems connecting to the City of
RIMMARMARMARMAMMETEMEWARMAMMEWARMAMMETEMEWARMAMMEWARMAMMETEMEUMEMEWARMARMAMMETEMEUMEMEWARMARMAMMETEMEUMEMEWARMARMAMMETEMEWARMAMMEURREUMEM San Benito Urban Areas UWMP 2025 Page 6-15
Hollister Reclamation facility has begun. This system will increase the use of recycled water in the District.
Recycled water will augment supply to agricultural users in the Hollister subbasin area. The DWWTP/WRF receives wastewater flow from all municipal and most industrial customers within Hollister City limits, including portions of the Sunnyslope service area, and, as of 2026, receives wastewater from SJB. The system treats water to disinfected tertiary recycled water standards through the use of a Membrane Bioreactor (MBR).
The DWWTP/WRF is currently capable of treating up to 4 MGD and the current dry weather average flow is approximately 3 MGD. The DWWTP/WRF can be expanded to accommodate peak flows of 5 MGD through the installation of additional membranes, when required by additional development.
The Hollister IWWTP began operating in 1971 and is located on 78 acres less than a mile east of the DWWTP/WRF (Figure 6-7). The facility was constructed to treat effluent from local tomato canneries and also treats storm water. Only one of the canneries, San Benito Foods, is currently in operation, from mid - June through mid -October. The IWWTP is a conventional aerated pond treatment system that produces secondary -treated discharge. The capacity of the IWWTP has been estimated to be as high as 7.5 MGD; however, the current RWQCB permit limits flows to 3.5 MGD during the canning season and 1.72 MGD of storm water during the non -canning season (HDR 2008a). The secondary effluent from the IWWTP is discharged to evaporation and percolation ponds, which recharge Hollister and San Juan area groundwater (RMC 2005). The number of industrial dischargers has significantly declined over the last 30 years and as of 2020, only one cannery discharged industrial wastewater to the IWTP (Wallace 2020).
Sunnyslope County Water District Wastewater Facilities
The domestic wastewater treatment plant serving the Ridgemark Estates community is managed by Sunnyslope. A new wastewater treatment plant was constructed in 2013 at the Ridgemark I facility (Figure 6-7). The new treatment plant is a sequential batch reactor facility with sludge handling facilities and four percolation ponds that can treat 330,000 gallons per day. In water year 2025, the total treated wastewater was 188 acre feet or approximately 168,000 gallons per day (Todd 2025). The previous Ridgemark II facility was converted to a pump station to pump wastewater to the new Ridgemark I treatment plant. At the Ridgemark II site, the treatment ponds and disposal ponds will remain as a backup facilities owned by Sunnyslope.
Sunnyslope has no plans to provide recycled water for irrigation in the next five years. In the past, Sunnyslope had considered providing recycled water for Ridgemark Golf Course, but this would require significant additional upgrades to its WWTP.
City of San Juan Bautista Wastewater Facilities
The City of San Juan Bautista has historically provided wastewater collection services to more than 900 residential, commercial, industrial, and institutional accounts. SJB owns and operates a wastewater collection system that consists of approximately 9.3 miles of gravity trunks and force mains and five lift stations, which has conveyed the flow to the San Juan Bautista Wastewater Treatment Plant (SJBWWTP).
The SJBWWTP is currently non -operational and SJB now conveys wastewater flow to the Hollister
RIMMAMMEURREUMEMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEUMEM San Benito Urban Areas UWMP 2025 Page 6-16
DWWTP/WRF. As background, the SJB WWTP is a tertiary treatment facility that includes a mechanical screen and influent pump station, sequencing batch reactor pond (SBR), flow equalization tanks, a denitrification pond pressure sand filters, and ultraviolet (UV) disinfection. Sludge is stored in lagoons, and wastewater was discharged to San Juan Creek, effectively leaving the North San Benito Basin. The original plant was a facultative pond plant. The last major improvement project, in 2010, upgraded Pond 1 to an aerated pond that functions as SBRs and split Pond 2 into three cells, which include the polishing pond and two sludge storage lagoons. The 2010 upgrade project also added a mechanical basket screen, a new dual media pressure filtration system, and UV disinfection system. In 2018, SJB removed 30 -years of accumulated sludge from Pond 2, to accommodate continued operation of the treatment plant. The tertiary treatment facility is only designed to handle 0.2 MGD, while there is some buffering capacity available in the SBR (1.6 MG), the available volume has not been enough to equalize the excess daily flow during peak flow conditions. Despite past upgrades, the facility has experienced operational constraints associated with its aging infrastructure and inherent limitations of lagoon -based treatment systems, particularly with respect to regulatory compliance reliability and long-term performance.
To address long-term wastewater management needs and water quality compliance, the City of San Juan Bautista Regional Water and Wastewater Solution was established. As described in the GSP, the Regional Solution involves importing high quality water from the West Hills WTP to San Juan Bautista, replacing groundwater use, removing residential self -generating water softeners, reducing industrial salt loading to SJB wastewater, and then conveying San Juan Bautista wastewater to the City of Hollister DWWTP/WRF.
The Regional Solution is part of the 2023 Master Plan process. The design for the San Juan Bautista Pipeline construction is underway, and water deliveries may start within the next two to three years. As of 2026, the Regional Solution has completed the wastewater pipeline project to connect SJB sewage to the DWWTP/WRF. This project has been supported by roughly $12.5 million in USDA funding (grants and loans) to replace failing infrastructure. The project ends SJB's requirement to operate its own treatment facility.
SJB does not currently provide recycled water, and future wastewater planning is focused on regional conveyance and treatment rather than expansion or modernization of local treatment or recycled water reuse infrastructure.
Other Wastewater Facilities
Wastewater treatment within the SBUA by parties other than the three municipal water purveyors is limited to the Cielo Vista Estates, operated by San Benito County, and private residential septic systems.
Cielo Vista Estates is a residential development within Sunnyslope's service area and includes approximately 75 single-family homes located at the intersection of Airline Highway and Fairview Road.
Previously, the wastewater from the community was treated by a Sequencing Batch Reactor (SBR) system operated by San Benito County. The system was closed in 2024 and the community is now connected to the Hollister WWTP.
Some private residences within the SBUA are still serviced by individual septic systems. No estimate has been made of the quantity of wastewater generated from these onsite wastewater systems.

6.2.5.3 RECYCLED WATER SYSTEM DESCRIPTION
The wastewater treatment facilities within the SBUA utilize a number of treatment methods, which result in varying effluent quality, as described above. Current requirements for recycled water use are administered by Title 22 of the California Code of Regulations, referred to hereafter as Title 22. The Hollister DWWTP/WRF has the capacity to meet the requirements for disinfected tertiary recycled water as defined by Title 22. The remaining wastewater treatment facilities produce effluent that meets the Title 22 requirements for undisinfected secondary recycled water. However, the effluent streams from all of the treatment facilities have high levels of TDS, which may preclude local reuse on orchards and vineyards or non-food bearing trees. The parties to the MOU have committed to reducing these high concentrations by reducing the TDS of supplied water as part of the Master Plan (HDR 2023). The Hollister DWWTP/WRF currently treats all wastewater flows to tertiary standards, but only disinfects what is used offsite for landscape irrigation.
As previously noted, the other wastewater treatment facilities (Ridgemark WWTP and SJB WWTP) produce undisinfected secondary effluent, with disposal through evaporation and/or percolation.
The current and anticipated future quantities of wastewater treated to recycled water standards are presented in Table 6-4 Hollister Retail, Table 6-4 Sunnyslope Retail, Table 6-4 SJB Retail, and 6-4 W.
Recycled water will be available from only Hollister's domestic wastewater treatment plant/water reclamation facility (DWWTP/WRF). There are no plans to provide recycled water from other facilities.
6.2.5.4 CURRENT, POTENTIAL, AND PROJECTED RECYCLED WATER USES
CURRENT USES
Offsite reuse of recycled water from the DWWTP/WRF takes place at Riverside Park (formerly known as the Brigantino Site) and previously occurred at the airport. Irrigation began in a limited capacity in 2009 and increased in 2010. In 2025, 80 AF of recycled water was delivered to Brigantino Park, while no recycled water was delivered to the airport site. The remaining treated wastewater from the DWWTP/WRF is currently disposed of by evaporation and percolation. The DWWTP/WRF will increase the quantity of disinfected tertiary recycled water that it produces as demand for recycled water increases, in accordance with the Master Plan. In Water Year 2025, an additional 406 AFY of recycled water was delivered to agricultural customers outside of the SBUA.
PLANNED VERSUS ACTUAL USE OF RECYCLED WATER
In the 2020 UWMP, recycled water use in the SBUA was projected to remain steady at 100 AFY by 2025.
The actual recycled water use in 2025 was 80 AF. In Table 6-5 Hollister Retail, Table 6-5 Sunnyslope Retail, and Table 6-5 SJB Retail the projected recycled water use from the 2020 UWMP is compared to the 2025 actual use. The volume of landscape irrigation is about the same, as recycled water has been prioritized for agricultural use outside of the SBUA. Sunnyslope nor SJB have plans to pursue recycled water as a supply source.

FUTURE USES
Potential Recycled Water Uses
Water recycling began with municipal irrigation but has shifted focus to provide recycled water to agricultural users beyond the SBUA. The system was expanded in 2014, including infrastructure and treatment capability to improve water quality for the purpose of agricultural irrigation. The system was further improved in 2015 when SBCWD (at a cost of about $1,000,000) installed 1.65 miles of additional distribution system piping and 30 metered delivery points to provide water for agricultural customers. In 2016, the Recycled Water Storage Pond was installed in "Pond 2" at the Domestic Waste Reclamation Facility (DWRF) to improve distribution system water quality and to help equalize recycled water production with irrigation demand.
Projected Recycled Water Use
In 2019, the District installed a series of sand media filters upstream of the Recycled Water Distribution System to improve water quality and allow agricultural customers to use drip irrigation and minimize backwash waste. These upgrades to the Recycled Water Storage Pond and distribution system cost approximately $1,500,000. Recycled water currently is provided to approximately 865 acres for agricultural production and landscape irrigation. Currently, these agricultural customers rely on additional CVP imports and groundwater pumping. If more irrigation demands are met by recycled water, groundwater pumping in the area could be reduced, increasing the available groundwater supply for the SBUA retailers.
There are no plans to expand recycled water use for municipal users. This is documented as the absence of entries on Tables 6-6 Hollister Retail, 6-6 Sunnyslope Retail, and 6-6 SJB Retail.
6.2.5.5 ACTIONS TO ENCOURAGE AND OPTIMIZE FUTURE RECYCLED WATER USE There are no current plans to increase recycled water use in the SBUA. Accordingly, no implementation strategies are listed on Table 6-6 Hollister Retail, Table 6-6 Sunnyslope Retail, Table 6-6 SJB Retail, Table 6-7 Hollister Retail, Table 6-7 Sunnyslope Retail, nor Table 6-7 SJB Retail. The District plans to distribute the recycled water produced by Hollister's WWTP for agricultural users outside the SBUA. Sunnyslope or SJB may pursue recycled water in the future but have no plans in place.
6.2.6 DESALINATION WATER OPPORTUNITIES
The 2023 Master Plan examined demineralization from municipal wells as a potential project to increase water supply reliability and improve water quality. Individual wellhead treatment was considered. The treated groundwater would be blended with the existing CVP and remaining groundwater supplies in the distribution system. The demineralization facilities would have a design capacity of 6,000 AFY and would produce an annual average supply of approximately 3,000 AFY. There are currently no plans to begin this project.
RIMMARMARMARMAMMETEMEWARMAMMEWARMAMMETEMEWARMAMMEWARMAMMETEMEUMEMEWARMARMAMMETEMEUMEMEWARMARMAMMETEMEUMEMEWARMARMAMMETEMEWARMAMMEURREUMEM San Benito Urban Areas UWMP 2025
The District, Hollister, Sunnyslope, and SJB are not considering desalination from ocean water or brackish surface water at this time because of a lack of such water sources in the region.
6.2.7 EXCHANGES OR TRANSFERS
Through its CVP contract, the District has the capability to engage in transfer or exchange with other CVP customers.
6.2.7.1 EXCHANGES
The District is the CVP wholesaler to agricultural and M&I users in addition to Hollister and Sunnyslope.
During the next water shortage, Hollister and Sunnyslope may be eligible to purchase additional water that the District has obtained from its water transfers with other CVP customers, has purchased on the spot market, and has banked at the Semitropic water bank. The amount of available water would be variable, based on the District's overall water needs. Potential short-term water agreements are expected to include 1,000 AFY from North Delta contract holders and an additional 250 AFY from exchange contractors in non -critical years.
Currently, the District has no municipal supply stored with Semitropic. 6,2,7,2 TRANSFERS
Over the past decade, the District has had an ongoing practice of purchasing out -of -basin water supplies to supplement its imported CVP supplies. These purchases have totaled 13,550 AF over the period.
Purchases are made, when available and cost-effective, from a variety of sources including irrigation districts north of the Sacramento —San Joaquin River Delta, the San Joaquin River Exchange Contractors, and other sources. These purchases range from single -year (spot market) purchases to multi -year agreements (typically up to 5 years).
6,2,7,3 EMERGENCY INTERTIES
Hollister and Sunnyslope share a connected water system and in an emergency, water can flow from one retailer to the other as needed.
To meet future demands and to secure more -reliable and higher -quality water, a transmission pipeline and associated facilities are in the design process to connect SJB's distribution system to the District's West Hills WTP. The San Juan Bautista Pipeline will form the infrastructure backbone for delivering high - quality surface water from the West Hills WTP to SJB to improve water quality in the distribution system.
The pipeline is a 10 -inch -diameter, gravity -fed, treated water transmission pipeline that will extend approximately 6.75 miles from the West Hills WTP to SJB's distribution system, where it will connect near Well No. 6. The design for the San Juan Bautista Pipeline construction is underway, and water deliveries may start within the next two to three years.

6.2.8 SUPPLY FROM STORAGE
Both the ASR and B.F. Sisk Dam Raise projects (more information in Section 6.2.10) will improve the reliability of the existing CVP water by providing opportunities for long-term storage of excess CVP water during wet years. That water would then be available during dry years, when CVP allocations are curtailed.
6.2.9 OTHER SUPPLIES
There are currently no other water supplies being used by Hollister, Sunnyslope, SJB, nor the District.
6.2A0 FUTURE WATER PROJECTS
As listed on Table 6-7, several future projects and programs could increase the reliability of the SBUA water supply. These projects all reflect the basin -wide partnership between Hollister, Sunnyslope, SJB, and the District. Additional information is provided in the Groundwater Sustainability Plan for the North San Benito Basin (Todd, 2021) and the 2023 Master Plan.
INCREASE GROUNDWATER WELL PRODUCTION CAPACITY
A major project has been termed the North County Project. It involves development of production well capacity in the northeastern portion of the North San Benito Basin to actively manage groundwater storage, to increase municipal water supply and drought year reliability, and to improve municipal water quality for the City of Hollister. The "North County" area has been defined mostly on the basis of relatively low concentrations of total dissolved solids (TDS) in groundwater. The effort is being led by the District in cooperation with the City of Hollister. The long-term goal of the project is to develop up to 5,000 acre- feet per year (AFY) of local water supply that is reliable during droughts. Phase I consists of siting, design, and installation of a new production well to serve the northern City of Hollister, beginning with a test well installed in 2021.
Test wells drilled in March 2021 as part of the North County Project were added to the North San Benito GSP groundwater level and quality monitoring program. Information about the wells (including ground surface elevation, screened intervals, and baseline conditions) is currently being collected.
In addition, SJB is considering a potential water treatment project associated with its Well #6. This treatment could allow increased groundwater production capacity. While the timing of that project remains uncertain and dependent on funding and implementation capacity, it represents an important long-term consideration for the City of San Juan Bautista.
DEVELOP SURFACE WATER STORAGE
The B.F. Sisk Dam Safety of Dams Modification Project includes bolstering the footings and raising the dam that creates San Luis Reservoir. This project, which is being developed by USBR and DWR, is intended to
RIMMAMMEUMEUMEMEWARMAMMEURREUMETAMARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEURREM San Benito Urban Areas UWMP 2025 Page 6-21
reduce seismic risk. A subsequent phase of the project is being developed to increase water storage capability in the Reservoir. The District diverts its CVP allocations from San Luis Reservoir. Additional storage would increase the capacity for carryover storage of surface water allocations in years when excess water is available, for increased flexibility to use the entire CVP allocation. All phases of construction are scheduled for completion in 2037.
The Pacheco Reservoir Expansion Project was a collaborative effort of Valley Water, San Benito County Water District, and Pacheco Pass Water District (PPWD) and included in the 2020 UWMP and GSP.
However, the project is no longer moving forward. On August 26, 2025, Valley Water's Board directed staff to cease work on the Pacheco Reservoir Expansion Project, withdraw its grant application, and wind the project down. Valley Water's decision was made for three main reasons: 1) USBR determined that it would not allow for the storage of CVP water in the expanded reservoir, 2) most recent cost estimate had escalated to $3.2B, 3) inability to identify and secure additional project partners. On January 30, 2026 Valley Water notified SBCWD that it was formally terminating the 2018 MOU governing development of the project.
EXPAND MANAGED AQUIFER RECHARGE (MAR)
A MAR study was conducted and completed in water year 2022. The District has planned a MAR project using injection wells, specifically Aquifer Storage and Recovery (ASR) and has begun implementation. The entire ASR project is planned to provide for injection and storage of up to 6,000 AFY of treated CVP water in wet years with recovery of up to 6,000 AFY of stored water in dry years.
This first phase, the accelerated drought response project (ADRoP), consists of up to five ASR wells, expansion of the West Hills WTP, and construction of pipelines to convey injection and recovery water between the five ASR wells, West Hills WTP, and the Hollister Distribution System.
In 2022 and 2023, the District successfully applied for and was awarded three individual grants to assist In funding ADRoP. These grants included DWR SGMA Implementation and Integrated Water Resource Management grants and a USBR small storage grant. In 2024, the District conducted environmental review of the project, Identified and negotiated locations for key project components, and developed final designs and specifications for construction of ADRoP infrastructure. In water year 2025, the District made significant progress on ADRoP. This included continued West Hills WTP expansion construction, finalization of property acquisition and state and federal environmental assessment and planning, and significant construction. The District successfully completed design work for all the wells, transmission infrastructure, and other facilities early in 2025.
Well drilling began in August 2025 and pipeline and other facility construction started shortly thereafter.
As of the end of the water year, four ASR wells have been constructed, and aquifer testing was underway.
A significant portion of the pipeline and other construction work was also completed in Water Year 2025.
The District anticipates completion of currently planned ADRoP construction work in Water Year 2026, including well testing, well equipping, site improvement, pipeline construction, etc.

ENHANCE CONJUNCTIVE USE
Hollister, Sunnyslope, SJB, and the District are engaged in several conjunctive use projects including the GSP, UWMP and AWMP, the SBUA Water and Wastewater Master Plan, and the WRA. These ongoing collaborative efforts represent the commitment to providing stable and secure water supply to the region.
The 2022 GSP for the North San Benito Basin provides the basic information, analytical tools, and projects and management actions for continued groundwater management, guided by SGMA and by locally defined sustainability goals, objectives, and metrics.
The UWMP and AWMP provide detailed information on the current and future water supply and demand in normal and drought conditions.
The Hollister Urban Area Water and Wastewater Master Planning Project (Master Plan) has been implemented since 2008 (now called the San Benito Urban Areas Water and Wastewater Master Plan) and it continues as an active planning process for the foreseeable future. Relative to groundwater sustainability, the Master Plan provides for conjunctive use of CVP supply, groundwater, wastewater, and recycled water. While CVP supply is sourced from beyond GSA jurisdictions and is not always reliable (see Plan Area section 2.1.2), the groundwater, wastewater, and recycled water are local sources and the conjunctive use planning increases reliability.
Water conservation efforts in San Benito County are conducted through the Water Resources Association (WRA). WRA is a cooperative effort among the District, City of Hollister, City of San Juan Bautista, and Sunnyslope County Water District. The WRA provides outreach and education, as well as rebate programs to help promote water conservation.
CONTINUE/ENHANCE WATER QUALITY IMPROVEMENT PROGRAMS
The District will continue to implement projects that will improve groundwater quality. These projects include implementing the Salt Nutrient Management Plan, which involves: collaborating with UC Davis toward reduced nitrate and salt loading by agriculture, supporting farmers in use of remote sensing to optimize fertilizer applications, enhancing cooperation with the County and local agencies on regulation of water softeners and onsite wastewater treatment systems, and enhancing outreach to North San Benito County stakeholders (including disadvantaged communities) on groundwater quality issues.
IMPROVE MONITORING PROGRAM
Water resource monitoring is described in the GSP and addresses surface water, groundwater levels and storage, and groundwater quality among other topics. This monitoring supports informed basin management and documents GSP performance in maintaining sustainability. The GSP Section 8 identifies recommended monitoring improvements, including:
• Investigation for Measurement of Agricultural Groundwater Extraction • Assessment of Monitored Well Sites to Refine Network
• Documentation of Well Construction in the Plan Area
RIMMAMMUMMUMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARMUM San Benito Urban Areas UWMP 2025
• Development of a Unique Well ID Program
• Enhancement of Surface Water Gaging
• Collaboration with State/Federal agencies for stream gages (Upper Tres Pinos) These improvements are described in more detail in the GSP. Combined with the District's existing groundwater management, these programs will allow the SBUA to continue to rely on the groundwater basin especially during drought.
6.3 ENERGY USE
As a requirement in 2020, suppliers must calculate the energy intensity of their water service. While the agencies have tracked their energy use in recent years, they have not systematically recorded energy uses from conveyance, storage, pumping, treatment, and distribution. Table 6-A below lists the possible uses of energy in the SBUA system. Hollister, Sunnyslope, SJB, and the District have all provided their available energy consumption. Sunnyslope's estimate includes both pumping and distribution for a period of six month, whereas Hollister tracks only energy for pumping. To account for distribution, it is assumed that total energy costs for groundwater are similar in Sunnyslope and Hollister and that energy use can be extrapolated from the six month period to one year.
SBCWD tracks energy use at each part of the water system from the turnouts, storage operations, pump stations, and treatment plants.
Table 6-10 (UWMP Table O -1a) summarizes the energy data. As shown, Hollister, Sunnyslope, and SJB use energy to extract and divert water and SBCWD uses energy for storage, conveyance, and treatment. To simplify the accounting, the process of Distribution in Table 6-10 only includes distribution for CVP water whereas the processes of Extract and Divert include distribution for groundwater. The value for Volume of Water Entering is defined as the volume of water sources before losses. It should be noted that the CVP energy use for storage, conveyance, and distribution also includes water for agriculture uses that are not accounted for in the volume of water entering the process. Additional upstream energy to convey CVP water to the basin is not included in the total energy used.
The energy intensity of the system is the total energy use divided by the volume of water in the system (kWh/AF). For the CVP system, the energy intensity is approximately 488 kWh/AF and the groundwater system energy intensity is approximately 838 kWh/AF. In 2025, the groundwater system supplied 33 percent of the water and used 45 percent of the total energy of the system, similar to the energy use documented in the 2020 UWMP.
While the energy data used in this analysis are approximate, the energy intensity of the systems can be applied to evaluation of potential water management projects. The three agencies will continue to monitor and collect data on the energy use of the system.

NOTES:
7.1 CONSTRAINTS ON WATER SOURCES
The SBUA has multiple water supply sources—CVP, groundwater, and recycled water —that increase overall water supply reliability. However, many factors could result in inconsistency of supply and shortages. These factors may include legal, environmental, water quality, and/or climatic considerations, as discussed below. Major factors affecting surface water supply from the CVP include environmental issues and climate change. The groundwater basin has a recent history of consistent supply but may be affected by climatic variations and poor water quality. Increased future uses of recycled water may be affected by the water quality of the source and legal/environmental constraints on use.
Hollister, Sunnyslope, SJB, and the District are addressing these potential constraints on water supply through development of a portfolio of supplies, improvement of facilities (e.g., treatment plant expansion and groundwater banking), and through demand management as summarized in the Water Shortage Contingency Plan (Section 8).
LEGAL
The Hollister basin has not been adjudicated, so specific groundwater rights have not been quantified.
Although the possibility exists that adjudication proceedings could be initiated, the success of local groundwater management activities with stakeholder involvement (including GSP preparation) reduces the likelihood that such lengthy and costly legal action will occur.
Imported water is secured for the future through contracts that include provisions for reductions in water supply. Such interruption of imported water would induce additional groundwater pumping that, depending on the magnitude and persistence of the interruption, could reduce groundwater storage and affect the reliability of the groundwater supply.
The collection, treatment, and disposal of wastewater and recycled water uses are governed by the MOUs between the County, the District, Hollister, SJB, and Sunnyslope and by regulatory requirements. The local parties have undertaken a coordinated effort to plan water supply and wastewater strategies for the SBUA.
ENVIRONMENTAL
The most likely environmental factors affecting SBUA water supplies would be reductions to CVP imports due to concerns over endangered species and water quality in the Delta. Expanded use of recycled water may also be limited by environmental concerns. Potential recycled water uses are and will continue to be in compliance with policies set by the RWQCB and other agencies. Other environmental concerns could include substantially increased pumping from other groundwater basin users, resulting in basin overdraft.
SGMA defines overdraft as involving undesirable impacts including chronic lowering of groundwater levels, reduction of groundwater storage, seawater intrusion, degraded water quality, land subsidence,
SIMIRMIAMMURVAMMUMENAMMEMMUMENAMMUMMMUMENAMMUMMMUNMMMUMMMUMENAMMUMMMUMENAMMEMMEMMEMMUMENAMMUMMMUMENAMMEMMEMMEMMUMENAMEM San Benito Urban Areas UWMP 2025
and surface water depletions with adverse impacts on beneficial uses. These undesirable results are addressed in the GSP preparation process (except seawater intrusion, which is not relevant to this inland basin.)
DELTA PUMPING RESTRICTIONS
The Sacramento -San Joaquin Delta is a key component to the state's water system (DWR 2009b), as much of the water that feeds the SWP and CVP flows through the Delta. The Delta is also home to a sensitive ecosystem with several federally listed threatened species. In 2007, pumping from the Delta for water supply was limited by a federal court to protect the Delta Smelt, a federally listed threatened species.
Further restrictions have been imposed to protect other fish species, including the Longfin Smelt and Chinook salmon. Further appeals have upheld these restrictions (Los Angeles Times 2014). These pumping limits directly affect the amount of CVP imported water available to the SBUA and other San Benito County users.
The SWRCB has developed the Water Quality Control Plan for the San Francisco Bay/Sacramento—San Joaquin Delta Estuary (Bay -Delta Plan). While unlikely to reduce any limitations, the Bay -Delta Plan is establishing water quality control measures and flow requirements. In 2018 the State Water Board adopted Basin Plan amendments establishing the Lower San Joaquin River flow objectives and revised southern Delta salinity objectives.
The Healthy Rivers and Landscapes (HRL) Program is a collaborative initiative in California designed to improve the ecological health of the San Francisco Bay/Sacramento-San Joaquin Delta (Bay -Delta) ecosystem. HRL aims to increase CVP and Delta resilience by pairing targeted environmental water flows with habitat restoration rather than relying solely on water export restrictions, like the 2018 Basin Plan amendments. This approach seeks to improve the long-term sustainability of the Bay -Delta ecosystem while providing more certainty for water users by reducing the likelihood of extreme, reactive regulatory cuts to water supplies. HRL is currently being considered by the State Water Resources Control Board and may be adopted late 2026.
WATER QUALITY
Water samples from the municipal wells are monitored for various water quality constituents. If these constituents are detected at concentrations higher than the drinking water standard or maximum concentration limit (MCL) set by the U.S. Environmental Protection Agency (USEPA) or the DDW, the well may be taken offline. In the past, municipal wells have been taken offline as a result of high nitrate concentrations. Although high nitrate concentrations can be treated, removal of wells from the system and fitting for treatment technology may temporarily impact the system and affect the cost of supply. In addition, availability of groundwater from municipal wells may be affected by regulatory changes that tighten water quality standards, for example, for chromium, which is naturally occurring in North San Benito or for emerging contaminants such as PFAS. These can be addressed with treatment, modification of groundwater pumping among wells, and blending.
RIMMAMMUMMUMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARMUM San Benito Urban Areas UWMP 2025 Page 7-2
As discussed in the supply section, local groundwater is highly mineralized and the relatively poor water quality may limit some uses of groundwater. The SBUA agencies are taking steps to improve water quality of the groundwater supply. In the meantime, groundwater is blended with CVP water to ensure adequate quality for supply and indirectly improved quality for wastewater and recycled water. There is no regulatory requirement, but the agencies may limit the volumes of groundwater used if insufficient imported water is available for blending.
As with groundwater, the water quality of recycled water (also characterized by high TDS concentrations) may also limit its potential uses. The 2008 Master Plan (HDR 2008a) and Updates (HDR 2017 and 2023) include procedures by which the quality of recycled water can be improved over time. The changing quality of recycled water was taken into consideration in the projection of future use.
CLIMATIC
The climatic events most likely to affect water supply are droughts, which are addressed in other sections of this report by examining historical droughts and considering their impact on current and future water supply and demand. It is notable that five of the six extreme drought years have occurred within the past 20 years, suggesting greater climatic variability in recent decades. In addition to climate variability, climate change can result in long-term loss of snowpack (affecting CVP supply) and increased evaporative losses.
Both short-term and long-term changes bring additional uncertainty to water supply management.
DROUGHT
Recorded droughts have been sufficiently intense and prolonged to temporarily affect groundwater levels in the basin but have not affected the long-term consistency of supply. However, paleoclimatic data indicate that extreme prolonged droughts have occurred in prehistoric California and current climate research indicates that extreme drought may occur more frequently with climate change. This is discussed in more detail below.
As reported in past UWMPs, basic review of groundwater hydrographs for wells in the basin suggested that one or even three consecutive extreme dry years did not have a discernable impact on groundwater levels. However, as experienced in recent drought, CVP allocations may be significantly reduced during these periods. As guided by the Master Plan process (HDR, 2008, 2017, and 2023), available imported water supplies are being managed conjunctively with local storage and supplies as available in drought.
In addition to the measures described above, San Benito County agencies (including Hollister, Sunnyslope, SJB, and the District), have adopted drought resilience measures in the 2026 San Benito County Drought Resilience Plan (Drought Resilience Plan) (Stantec Consulting Services 2026). This plan establishes how the County's Drought and Water Shortage Task Force and other responsible agencies will coordinate responses to water supply vulnerabilities affecting domestic wells and state small water systems. Through advanced planning, interagency coordination, and response procedures, the Drought Resilience Plan strengthens countywide preparedness for drought -related supply interruptions and supports overall water service reliability.

GLOBAL CLIMATE CHANGE
According to the Intergovernmental Panel on Climate Change, global warming could significantly alter California's hydrologic cycles and water supply. These impacts include decreased Sierra snowpack, increased temperatures, more severe droughts, sea level rise, and increased floods. Climate models indicate that precipitation as rainfall is expected to increase as snowfall decreases over the Sierra Nevada and Cascade mountain ranges. By the end of this century, the Sierra snowpack is projected to be 48 to 65 percent less than the historical average (DWR 2026). This reduction would directly impact the volume of imported water available for all the District CVP customers, including Hollister and Sunnyslope. Sierra snowmelt feeds rivers that flow to the Delta, the source of CVP imported water. The Delta is also at risk from the predicted increases in climate variability associated with climate change. More severe flooding and rising sea levels threaten the waterways that serve as a vital link in the CVP system within the Delta.
Climate change also is projected to increase regional temperatures and cause more variable weather patterns. The minimum daily temperature in California has increased over one degree Fahrenheit and continues to rise (DWR 2021b). In addition to decreasing snowpack, these increased temperatures may also increase water demand. Higher temperatures could increase water demand throughout the state through increased agricultural irrigation and increased outdoor residential and commercial irrigation.
Changing weather patterns could cause more severe flooding that disrupts surface water storage and conveyance systems.
Climate change has already been incorporated into future supply projections for all SBUA water sources.
The CVP projections are based on the observed allocations since 2007 and not on the Cal Sim II simulations that show a more optimistic future. The groundwater availability is limited to the sustainable yield developed for the North San Benito GSP. The future modeling, on which the sustainable yield is based, represents a continuation of existing land and water use patterns, but with anticipated effects of future climate change on local hydrology (rainfall recharge and stream percolation) and on the availability of imported water supplies.
CATASTROPHIC WATER SHORTAGE
The Urban Water Management Planning Act requires that water purveyors describe actions to be taken in the event of catastrophic water supply interruption, such as earthquake and regional power outage.
Regional power outages represent a potential interruption in water supply treatment and conveyance.
REGIONAL POWER OUTAGE
Heat waves and wildfire conditions have resulted in power outages in the SBUA that disrupt water supply.
As part of the Drought Resilience Plan, power outages can activate the Warning Stage and if prolonged, the Emergency Stage. In the Warning Stage, County staff increases communication and outreach activities and initiates coordination with other entities. County staff may consider recommending that the Task Force and/or the County Board of Supervisors activate the County's water conservation policies outlined in the Water Shortage Contingency Plan. In the event of an Emergency Stage, County staff, in coordination
RIMMARMARMARMAMMETEMEWARMAMMEWARMAMMETEMEWARMAMMEWARMAMMETEMEUMEMEWARMARMAMMETEMEUMEMEWARMARMAMMETEMEUMEMEWARMARMAMMETEMEWARMAMMEURREUMEM San Benito Urban Areas UWMP 2025
with the Task Force and County Board of Supervisors, would declare a water shortage emergency and activate the Water Distribution Plan described in the following section, "Emergency and Interim Drinking Water Distribution Plan." (Stantec Consulting Services Inc. 2026) To ensure that the water system is capable of providing an adequate level of service during power outages, Hollister Well Nos. 4 and 5 are equipped with standby power. Hollister also has portable generators to supply emergency power for the other active wells (HDR 2008a). Sunnyslope has portable generators at all potable well sites, wastewater pump stations, and their wastewater treatment plant. A backup generator has been installed at West Hills WTP. The Lessalt treatment plant has been wired with a quick -connect electrical connection so that a rental generator could easily be brought in and quickly connected to power the plant if needed.
NATURAL DISASTERS
Similar to power outages, natural disasters can disrupt the water supply, and the Drought Resilience Plan can be activated with the Warning Stage or Emergency Stage. In the Warning Stage, County staff increases communication and outreach activities and initiates coordination with other entities. County staff may consider recommending that the Task Force and/or the County Board of Supervisors activate the County's water conservation policies outlined in the Water Shortage Contingency Plan. In the event of an Emergency Stage, County staff, in coordination with the Task Force and County Board of Supervisors, would declare a water shortage emergency and activate the Water Distribution Plan described in the following section, "Emergency and Interim Drinking Water Distribution Plan." (Stantec Consulting Services Inc. 2026)
Disasters such as earthquakes could disrupt water delivery infrastructure. The wholesalers—USBR and SBCWD—that provide imported water to the SBUA are taking steps to ensure water supply reliability.
USBR is responsible for about 370 storage dams and for dikes that form a significant part of the water resources infrastructure for the western United States. As the owner of these facilities, USBR is committed to providing the public and the environment with adequate protection from the risks inherent to collecting and storing large volumes of water for later distribution and/or release (USBR 2016). The District routinely monitors the conditions of Hernandez and Paicines.
Recognizing the proximity of the San Andreas and Calaveras faults, the City of Hollister, San Benito County, and the District have a joint water shortage emergency response plan included in Appendix E.
7.2 WATER SERVICE RELIABILITY ASSESSMENT
The California Urban Water Management Planning Act requires that each water supplier provide an assessment of the reliability of its water supply during normal, dry, and multiple dry years. This section considers the impact on water supplies during a single extreme dry year and a multiple dry year period (defined as a drought lasting five consecutive years). In addition, a catastrophic water shortage could also occur, for example, as a result of earthquake damage, regional power outage, or water quality emergency.
This section presents the response to potential water shortages for Hollister, Sunnyslope, and the District,

including catastrophic water supply interruption and drought. Tables 7-1 Retail and 7-1 W show the base years selected to define average, single -dry year, and multiple -dry year period for each water source.
7.2.1 WSRA YEAR -TYPE CHARACTERIZATION
7.2.1.1 TYPES OF YEARS
GSP Regulations require quantification of the water budget by water year type, which is a classification based on the amount of annual precipitation in a basin. It should be noted that the water year type is based on hydrologic water year October to September. This UWMP reports on calendar year January to December.
Figure 7-1 shows annual rainfall in Hollister from water year 1976 through 2025; the average annual amount is 12.9 inches. Water year type is intended to aid in the evaluation of information such as water level hydrographs and groundwater storage changes. Table 7-A documents the classification developed for the North San Benito GSP, which describes five water year types (critically dry, dry, normal, above normal, wet). The methodology for defining the water year types is based on DWR's Water Budget Best Management Practice (BMPs) Document (DWR, 2016). For North San Benito, the annual rainfall amounts in Hollister over the period of record (1976-2025) were expressed as percentages of average annual rainfall. These were then sorted into quintiles, reflecting the five categories. The sorting into quintiles resulted in the classification shown in Table 7-A.
The water year classification is based on local Hollister rainfall as representative of the Basin and surrounding watershed. Local precipitation is important for the overall water balance of the area. While CVP allocations are critical to avoiding overdraft and are based on precipitation patterns in the Sierra Nevada and Central Valley, local precipitation has a larger effect by volume on the groundwater basin.
Surface water recharge, deep percolation, and irrigation demand are all dependent on local rainfall.

NORMAL YEAR
Rainfall data have been collected monthly in the Hollister area since 1875. Precipitation and other weather data have been collected from a California Irrigation Management Information System (CIMIS) station located by the District office in Hollister since June 1994 (Station #126). Average conditions are considered the same as Normal as defined in Table 7-A.
Rainfall in water years 1992, 2003, 2009, 2019, 2024 was about average. For the purposes of this UWMP, calendar year 2019 is selected as the typical average year for supply because the most recent year is representative of current basin operations and not an extremely wet year like 2023.
SINGLE -DRY YEAR
DWR guidelines suggest that a single dry year should be the lowest supply available to the retailers, in addition to lower precipitation. Supply has been reduced due to decreases in the CVP allocations for both agricultural and M&I uses. A decrease in agriculture allocations, while not affecting the retailers directly, indirectly affects supply as groundwater pumping from other uses in the basin generally increases. This increased groundwater use could affect groundwater availability in the long term. Critically dry years, as defined by the GSP water year type include 1990, 2007, 2013, 2014, and 2022.
In water year 2021, the year selected as a single dry year, local precipitation was 6.58 inches, 50 percent of normal. In addition, CVP allocations (contract year 2021-2022) for agricultural and M&I users were 0 percent, the first time the District had to apply for a Public Health and Safety allocation. The low allocations and low precipitation resulted in significant groundwater level drawdown. Accordingly, calendar year 2021 is representative of a severe single -dry year.
FIVE -CONSECUTIVE -YEAR DRY YEAR PERIOD
DWR guidelines suggest that a five -consecutive -year period should represent the lowest average water supply availability for a consecutive multiple year period (now defined as five or more consecutive dry years). As with the single dry year, CVP allocations significantly affect available supply.
In water years 2012 through 2016, CVP allocations for both agricultural and M&I users were the lowest on record. For example, the M&I allocation ranged from 25 to 75 percent of historical use for years. In addition, average annual precipitation for the five years was 10.58 inches, or 79 percent of normal. While other five-year periods had lower rainfall, the low rainfall during this period (combined with the low CVP allocation) significantly decreased the retailers' available water supply. While the dry years between 2021- 2022 were also dry, they were preceded and followed by normal to wet years, limiting the number of years in the dry year period. Based on these considerations, the representative five-year drought selected for reliability assessments was 2012-2016 because it combined low precipitation with historically low CVP allocations.

7.2.1.2 SOURCES FOR WATER DATA
Information regarding local climate conditions is available from the CIMIS station located in Hollister, while imported CVP allocations are available from the USBR. Groundwater availability and storage change are reported in the District's Annual Groundwater Reports (Todd 2026).
7.2.2 WSRA SUPPLY AND DEMAND COMPARISON
Projected demands used in the Water Service Reliability Assessment (WSRA) are based on the demand projections in Chapter 4 and assume implementation of normal conservation standards. Dry -year adjustments are discussed below. In the years when there is a surplus of supply when compared to demand, it is assumed imported water will be maximized to preserve water quality and create a reserve for future use. In years where there is a deficit, WSCP measures will be enacted to reduce demand. 7,2,2,1 NORMAL YEAR
Table 7-2 characterizes the SBUA's normal year water service reliability. This table compares the normal year supply totals to the normal -year gross water use totals for the 20 -year projection horizon (based on Tables 4-3 and 6-9). Table 7-2 W shows the supply reliability of CVP imported water for the District.
Table 7-2 R shows the projected supply totals and demands in normal years from 2020 through 2045 in five-year intervals.
7.2.2.2 SINGLE DRY YEAR
Table 7-3 R shows the supply totals and demands for a single dry year (similar to 2022) for the 20 -year planning horizon. This table compares the single dry year supply total to an adjusted gross water -use total for the SBUA. As shown on Table 7-1 CVP, the CVP contract allocation is expected to be at a minimum of 33 percent. Recent critically dry year allocations and Public Health & Safety actions support a planning assumption of approximately 33 percent minimum availability, though future allocations are not guaranteed. As noted above, the District maintains additional reservoir storage that would supplement CVP supply with 1,000 AFY and an additional 1,000 AFY would come from ADRoP.
For planning purposes, water used during a single dry year is assumed to be the same as during a normal year (see values from Submitted Table 4-3). Water demand may decrease during a dry year if users are responsive to conservation education and outreach campaigns or if temporary water use restrictions, specified in the WSCP in Chapter 8, are enacted. Conversely, water use may increase if irrigation water application is increased due to lower rainfall. The SBUA agencies will monitor water use during a dry year and implement outreach or WSCP stages as appropriate.
The District supplies approximately 200 AFY to M&I customers other than the Hollister, Sunnyslope, and SJB. This non -urban M&I demand will be met during normal years, a single dry year, or the first year of a multiple year drought. In the event of a prolonged drought, this non -urban demand may be unmet in order to provide the minimum human health and safety for urban residents.

Table 7-3 R provides a comparison of supply and demand in a single dry year. In a typical single dry year, CVP allocations are expected to be 33 percent of the contracted amount less losses, which is a total of 2,450 AFY. Recycled water is expected to be fully available at 80 AFY. In addition, it is assumed that the District can use reserve water stored in San Justo reservoir up to 1,000 AFY. The WSCP would be triggered to Stage 2 and would achieve the required conservation up to 20 percent. The supply shortage in a single dry year is expected to be 12 percent. Additional supply to District M&I customers outside of the SBUA area is needed to meet demand in a single dry year.
7.2.2.3 FIVE CONSECUTIVE DRY YEARS
Table 7-4 R and Table 7-B show the supply totals and demands for each year of a multiple year drought (similar to 2012 through 2016) for the same time period. As with the single dry year, supply is limited by the CVP allocations, but additional CVP supplemental water is available, including supplies from ADRoP.
While based on the 2012-2016 drought, the later years of the drought were assumed to have minimal public health and safety allocations (not the actual allocations that occurred in the corresponding year).
Table 7-1 W shows the District's CVP allocation during the multiple dry year period. Table 7-1 CVP shows what would be available to the SBUA agencies (the District's allocation less other M&I users and system losses). The District supplies approximately 200 AFY to non -urban M&I customers other than Hollister, Sunnyslope, and SJB and will deliver that supply in the first year of a multiple year drought. In the event of prolonged drought, this non -urban demand may be unmet in order to provide minimum human health and safety supply for urban residents.
The multiple dry year projections suggest that at least voluntary restrictions for Stage 1 (10 percent reduction) should be implemented for the first two years and then Stage 2 (up to 20 percent) in all following dry years.
The District relies on a diverse portfolio of imported water, groundwater, and recycled water, and has made plans for additional supplemental imported water in dry years. In general, the groundwater pumping is expected to be at least as much as current pumping (2,230 AFY in 2025) and to increase as needed to help meet demands. For planning purposes, CVP allocations are assumed to be limited in all years other than the normal year 2025. The available CVP supplemental supply (San Justo reserves, contractor and exchange water) is used as needed in dry years. As noted, in all dry years, it is expected the WSCP Stage 1 will be enacted to encourage a 10 percent reduction in water demand. As drought continues beyond the first two years, WSCP Stage 2 will be needed to encourage a 20 percent reduction.
Table 7-B summarizes the projected annual water supply, demand, shortage magnitude, and corresponding WSCP response for each year of the representative five-year consecutive year dry period The table illustrates how available supplies are managed over time through use of groundwater, recycled water, supplement CVP supplies, and staged demand management measures. The most constrained years occur in the middle of the drought sequence when imported supplies are lowest and stored supplemental supplies have been partially depleted, while demand remains high. Continued groundwater availability and implementation of the WSCP are expected to maintain service reliability throughout the planning scenario. WSCP stages shown are planning assumptions and may be adjusted based on actual conditions.
