Body
SUMMARY:
This agenda item presents the Fiscal Year (FY) 2026-27 rate-setting process for Santa Clara Valley Water District’s (Valley Water) groundwater production charges and other water charges (treated surface water, raw surface water, and recycled water). It provides an update on key issues that pertain to setting the charges that will take effect on July 1, 2026 (Attachment 1).
Each year, the Board establishes groundwater production charges for four zones of benefit (Zone W-2 in the North County and Zones W-5, W-7, and W-8 in the South County) in accordance with Section 26 of the District Act. Although not specified under the District Act, the Board also sets surface water charges, recycled water charges, treated water surcharges, and the amount of the State Water Project cost to be recouped through the State Water Project tax within the framework of the groundwater charge setting process.
The Water Utility taxing and pricing policy, Resolution 99-21 (Attachment 2), and legal requirements guide staff in the development of the overall structure for these charges.
The FY 2026-27 surface water charge-setting process will be conducted consistent with Proposition 218’s requirements for property-related fees for water services as detailed in Board Resolution 12-10 (Attachment 3).
Proposition 26 applies to Valley Water’s groundwater charges. For a groundwater charge to qualify as a nontax fee under Proposition 26, it must satisfy both of the following requirements:
1. It must be no more than necessary to cover the reasonable costs of the government activity, and
2. The manner in which those costs are allocated to a payor bear a fair or reasonable relationship to the payor’s burdens on, or benefits received from, the government activity.
The FY 2026-27 groundwater production charge setting process will be conducted consistent with Proposition 26 requirements.
Consistent with the District Act, procedural requirements for property related fees and charges, like holding a public hearing and noticing well owners, are followed.
Under the District Act, Section 26.6, an annual report referred to as the Report on Protection and Augmentation of Water Supplies (PAWS) is to be filed with the Clerk of the Board on or before the first Tuesday in April. A public hearing must be held on or before the fourth Tuesday in April and it must be noticed to the public in a newspaper of general circulation at least 10 days in advance. In addition, all well owners and well operators on record are notified of proposed groundwater production increases in writing, and of the public hearing, at least 45 days in advance. Groundwater production charges must be determined for the ensuing fiscal year prior to July 1 of the ensuing fiscal year. For each zone of benefit, groundwater production charges must be fixed and uniform per acre-foot for agricultural water and fixed and uniform per acre-foot for all water other than agricultural water.
Under the District Act, Section 26.3, groundwater production charges are to be used for the following purposes:
1. Pay for construction, operation, and maintenance of imported water facilities;
2. Pay for imported water purchases;
3. Pay for constructing, maintaining, and operating facilities which will conserve or distribute water including facilities for groundwater recharge, surface distribution, and purification and treatment; or
4. Pay for debt incurred for purposes 1, 2, and 3.
The Board has established groundwater benefit zones in accordance with the District Act. The objective of establishing different groundwater benefit zones is to recover only those costs for benefits resulting from District activities within that zone. The benefits and costs which are apportioned to zones by customer class are presented in the annual PAWS report.
The groundwater production charge reflects the benefit of District activities to protect and augment groundwater supplies and is applied to water extracted from the groundwater basin in Zones W-2, W-5, W-7, and W-8. Zone W-2 encompasses the Santa Clara groundwater subbasin north of Metcalf Road or the North County. Zone W-5 overlays the Llagas subbasin from northern Morgan Hill south to the Pajaro River. Zone W-7 overlays the Coyote Valley south of Metcalf Road to northern Morgan Hill, and W-8 encompasses the area below Uvas and Chesbro Reservoirs.
Valley Water protects and augments water supplies for the health, welfare, and safety of the community. County-wide, groundwater replenished by the District makes up, on average, two-thirds of the groundwater used by residents, retailers, and businesses. The District replenishes the groundwater basins with local water and purchased water imported from the Sierra Nevada mountains and conveyed thru the San Francisco Bay Delta Estuary. The activities undertaken by the District to acquire, monitor, recharge, and protect the water supply are funded, in part, through groundwater production charges.
Water Usage Trend
The estimated actual District managed water use for FY 2024-25 is approximately 219,000 acre-feet (AF), which is about 3,000 AF lower than budgeted water use. Lower water use when compared to last year’s budget was likely due to several factors including lower rebound from the 2023 drought than was anticipated combined with milder weather (dry but slightly cooler than usual).
Consistent with last years reduced long-term projections, adopted budget FY 2025-26 water use is 219,000 AF. The water usage forecast may be modified as necessary during the upcoming rate setting process.
FY 2026-27 Planning Scenario Ideas
Staff anticipates the need to provide several groundwater charge projection scenarios for Board consideration during this rate-setting cycle. Staff would appreciate Board feedback on the following assumptions and scenario ideas:
Baseline assumptions:
• District-managed water use projection of around 224,000 acre-feet
• Projects included in the adopted FY 26-30 CIP 5-Year Plan
o Anderson Dam Seismic Retrofit with WIFIA loan
o Rinconada Water Treatment Plant
o Pure Water Silicon Valley (Phase 1 Demonstration Facility & Phase 2 Full-Scale Direct Potable Reuse (DPR) Facility)
o Dam Safety Program: Almaden, Calero, Coyote & Guadalupe
• Water rates will fund 3.23% of Delta Conveyance Project planning costs
• State Water Project (SWP) Tax (excluding Delta Conveyance Project costs) may be needed to pay for all, most, or some SWP costs
• Master Plan Project placeholders: SCADA, Water Treatment Plants & Distribution System
• Agricultural rates remain at 10% or less of lowest groundwater charge zone Municipal & Industrial rate
Scenario Ideas:
1. Baseline
2. Baseline including expanded participation in Sites Reservoir
Based on Board feedback, various groundwater charge projection scenarios will be provided for Board consideration in early January 2026.

ENVIRONMENTAL JUSTICE IMPACT:
The annual Groundwater Production Charge setting process addresses water supply equity by ensuring a cost-effective, high-quality supply is available for all of Santa Clara County, including disadvantaged communities.
FINANCIAL IMPACT:
Depending on the direction provided by the Board, there could be a future financial impact to the Water Utility.
CEQA:
The recommended action does not constitute a project under CEQA because it does not have the potential for resulting in direct or reasonably foreseeable indirect physical change in the environment.
