Napa County sets first groundwater sustainability fees
Growers will pay a combined $44.44 per acre under first-year rates the board approved in August, trimmed by $750,000 from the agency's reserves.
NAPA: Napa County's groundwater agency has set its first-ever sustainability fees, charging agricultural landowners a combined $44.44 per acre in a first year that regulators softened with $750,000 from the agency's fund balance.
The board overseeing the Napa Valley groundwater sustainability agency approved the first-year fee schedule on Aug. 11, according to the county's announcement. The county says the approved rates came in about 55 percent below the maximum rates considered earlier in the process.
Agricultural landowners will pay a base rate of $17.53 per planted acre, plus an additional $26.91 per acre for groundwater-irrigated acreage. Domestic and other self-supplied groundwater users will pay $28.17 per parcel, and public water systems will pay $58.47 per acre-foot of water pumped.
The fees apply only to property inside the Napa Valley Subbasin. Properties served by municipal water in Napa, St. Helena, Calistoga and Yountville are excluded, the county said.
The $750,000 transfer from the agency's fund balance directly reduced what landowners owe in the program's first year, according to the county's summary of the vote.
A decade in the making
The fees fund implementation of the valley's state-approved groundwater sustainability plan. The agency was created in December 2019 under California's 2014 Sustainable Groundwater Management Act, submitted its sustainability plan in January 2022 and won state approval in January 2023, according to the county's groundwater page. The plan's target for a sustainable basin is 2042.
State law requires at-risk basins to reach sustainability within 20 years of plan approval, and the fees pay for the monitoring, modeling and management work the plan requires. Future fee years will be set through the same public process, with the board weighing actual program costs against what landowners can bear.
The geography of the fee matters as much as the rates. Only land inside the Napa Valley Subbasin pays, which means properties on city water in Napa, St. Helena, Calistoga and Yountville sit outside the program. The cost falls on the valley's groundwater pumpers: the farms, rural homes and water systems that draw directly from the basin the plan is meant to protect.
For winegrowers already navigating a difficult market, the new line item arrives at a delicate moment. Industry coverage of the fee proposal earlier this summer noted concern among growers about added costs layered onto farming budgets during a downturn.
County staff say the first-year schedule is designed to keep the program funded while the agency builds its long-term monitoring network. What growers pay in year two will depend on how the board reads both the basin's data and the industry's balance sheets.
