​Napa Valley Grapegrowers is pleased to share that the Napa County Board of Supervisors voted unanimously today to approve a revised fee structure for the county's Groundwater Sustainability Agency (GSA), resulting in a projected 50-60% reduction in fees for agricultural users in fiscal year 2026-27.

The board adopted a revised budget that draws down the GSA's existing fund balance rather than collecting the full program cost through user fees in the current year. Key adjustments include:

• Charges for services were reduced from approximately $2.168 million to $931,000
• The fund balance will be decreased by roughly $750,000 to offset the difference
• Agricultural users can expect their per-acre fees to reflect the 50-60% reduction once final calculations are complete

​County staff will finalize fee amounts after a July 10 feedback deadline, which will ensure growers who are dry farming, have removed vines, or are using surface or recycled water are properly accounted for. A formal resolution with specific fee amounts for FY 2026-27 will come before the board on July 28.

​The original fee postcards sent to agricultural users created a significant financial shock across the community. NVG, along with Napa Valley Vintners, Winegrowers of Napa County, and the Napa County Farm Bureau, submitted joint policy recommendations calling for a revised approach that minimizes the impact while preserving the integrity of the groundwater program. The board's response reflects those shared concerns.

Napa County staff made clear that fees will continue to evolve as the program matures. Growers should be aware that the current reduction is made possible in part by drawing on fund balance reserves, which are not unlimited. The county is committed to identifying savings within the work plan, and officials signaled they are reconsidering spending in areas that have not yielded measurable results.
​
Supervisors also expressed strong interest in moving toward metering and monitoring, and noted that long-term fee stability will depend on both reducing groundwater use and increasing storage through tools like floodplain reconnection and infiltration opportunities.

​This outcome is a meaningful win for Napa Valley growers and reflects what is possible when the agricultural community speaks with a unified voice. We are grateful for the collaboration with our industry partners and encouraged by the board's responsiveness during these challenging times in our industry. Their ability to listen and adapt signifies a strong and respectful working relationship for the betterment of our entire county.   

​Water has always been at the heart of sustainable farming in the Napa Valley. As California's groundwater regulations move from planning into implementation, Napa Valley growers are entering a new phase of compliance, and NVG is with you every step of the way.
​
Here is what you need to know right now.

In December 2025, the Napa County Board of Supervisors adopted groundwater sustainability fees for the Napa Valley Subbasin. These fees fund the state-mandated Groundwater Sustainability Plan (GSP), which establishes a 20-year framework for managing the subbasin's water resources responsibly.

Fees apply to parcels located outside the municipal water service areas of Calistoga, St. Helena, Napa, and Yountville. If you are unsure whether your property is affected, use Napa County's Online Public GIS Map to check your parcel. Fees will appear on property tax bills in August 2026.
​
Exact fee amounts have not yet been finalized.

​We are pleased to report that NVG's advocacy is making a difference. Working alongside industry partners, NVG brought grower concerns directly to county leadership regarding the initial financial burden of these fees. At the June 16, 2026, Napa County Budget Hearing, the Board of Supervisors heard those concerns and directed staff to explore ways to reduce fees in this first year of implementation. We will continue to keep members informed as this process develops.

Growers who dry farm may qualify for a lower fee rate, applied only to dry-farmed acres. To be eligible, contact the Napa County Groundwater Sustainability Agency (NCGSA) by July 10, 2026:

• Email: [email protected]
• Phone: 707-253-4471

Do not miss this deadline if you believe your operation qualifies.

NCGSA staff are hosting two virtual Q&A sessions to answer grower questions about the fees and the GSP. Both are open to the public.

• Wednesday, June 17, 3:00–4:30 PM (today)
• Wednesday, July 1, 5:30–7:00 PM

Registration is required. We encourage growers and vineyard managers to attend and come with questions.

This is not a new issue for NVG. For several years, we have actively engaged in the GSP process on behalf of Napa Valley growers, working to ensure that the realities of vineyard water use are understood and reflected in county policy.

Our ongoing advocacy includes:

• Representing growers on the GSP Advisory Committee
• Providing public comment and presentations to the Technical Advisory Group (TAG) and the Groundwater Sustainability Agency (GSA)
• Regular correspondence with county staff to advance effective water management strategies

​As a direct result of NVG's continued engagement, Napa County has committed to developing incentive programs for growers who have already implemented effective water conservation practices and are willing to share their data with the county. NVG will continue participating in stakeholder discussions as those programs take shape.

The GSP is designed to keep groundwater resources at or above 2015 levels, measured across six sustainability indicators including groundwater levels, storage, water quality, land subsidence, and surface water interaction.

Growers who need to reduce pumping have a range of practical options available this season:

• Stretch irrigation intervals where possible
• Manage canopies actively (hedge often, reduce leaf area early)
• Switch to surface water or recycled water if available
• Use shade cloth and ET-reducing tools to lower vine stress
• Monitor vine water status with pressure chambers or sap flow sensors

For longer-term planning, choices around rootstock selection, row orientation, soil ripping depth, and on-site water storage can meaningfully reduce groundwater dependence over time.

​Protecting the Napa Valley Subbasin is a shared responsibility, and Napa Valley growers have long been leaders in efficient, thoughtful water stewardship. NVG will continue to advocate for fair, science-based implementation of these regulations while helping members navigate the path forward.

This episode of Grown in Napa Valley highlights both the business realities and opportunities facing Napa Valley grape growers. In the first segment, Caleb Mosley speaks with Michael Cuffe of Napa Valley Creative Agency about a marketing audit program offered through NVG and funded by the Western Extension Risk Management Education (ERME) program. Cuffe discusses how many growers, particularly those who have relied on long-term contracts for decades, now find themselves needing to market their vineyards for the first time. He emphasizes the importance of basic branding tools such as websites, professional photography, storytelling, and social media presence, while encouraging growers to highlight the prestigious wineries and wines their vineyards have supplied over the years. Despite current industry challenges, Cuffe remains optimistic about Napa Valley's future and believes growers who invest in telling their story will be better positioned for long-term success. 
​
In the second segment, Remi Cohen, President and CEO of Domaine Carneros, joins Caleb for Glass with a Grower and shares her journey from vineyard-focused viticulturist to winery executive. Cohen reflects on the importance of connecting vineyard practices to consumer storytelling, noting that every grower plays a critical role in promoting Napa Valley wine. The conversation explores Domaine Carneros' history, sparkling wine production, sustainability initiatives, and the challenges of the 2026 growing season, including an unusually early start followed by erratic weather. While acknowledging ongoing market pressures, Cohen encourages growers to remain positive, continue sharing the value of Napa Valley agriculture, and focus on innovation, hospitality, and long-term resilience as the industry adapts to changing conditions.
