​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.

On Friday, May 22, the Napa Valley Grapegrowers had the privilege of hosting a remarkable group of visitors: a cohort of Ukrainian agri-tech startup founders participating in the UC Berkeley Agro Accelerator program. The afternoon, held at the iconic V. Sattui Winery in St. Helena, was a working session designed to bridge two worlds: the deep-rooted agricultural tradition of Napa Valley and the innovative, technology-driven perspective of a new generation of global entrepreneurs.
​
This was not a wine tourism stop. It was a genuine exchange between professionals who share a common commitment to advancing agriculture through science, innovation, and collaboration.

The UC Berkeley Agro Accelerator brings together agri-tech companies that already have products and market traction, but are looking to scale, sharpen their investor readiness, and learn how demanding agricultural markets evaluate new technologies. The cohort represented a wide range of innovation areas including precision agriculture, IoT hardware, livestock management, greenhouse automation, and farm data platforms.
​
Napa Valley was chosen as the closing experience of their two-week California program for good reason. Our region represents a global standard of excellence in high-value agriculture, and offers a compelling case study in how a sophisticated farming community evaluates, adopts, and integrates new technologies over time. The afternoon was designed to help the founders reflect on the human side of ag-tech adoption: how trust is built with growers, why some solutions succeed while others struggle to gain traction, and what it takes to become a genuine partner to farmers rather than just a vendor.

The Napa Valley wine community has long understood that stewardship extends beyond the vineyard rows. It also means advocating for thoughtful policies that sustain agriculture, protect the Agricultural Preserve, and ensure that grape growing remains viable for generations to come.

Over the past year, the Napa Valley Grapegrowers has been working closely with three key partners — Napa Valley Vintners, Napa County Farm Bureau, and Winegrowers of Napa County — to develop a shared set of recommendations for local policy improvements that support Napa’s agricultural community.
​
Together, the four organizations represent thousands of growers, wineries, and agricultural businesses that form the backbone of Napa County’s rural economy and landscape.

This initiative began more than a year ago, when leadership from the four organizations came together to identify areas where local policies could better reflect today’s agricultural realities. Through ongoing conversations with elected officials, county staff, and community stakeholders, the groups developed a joint set of recommendations designed to ease unnecessary regulatory burden, modernize outdated policies, and strengthen protections for agriculture.

The result is a unified policy document delivered to the Napa County Board of Supervisors outlining both immediate actions and longer-term planning priorities that support the continued vitality of Napa County agriculture.
​
This collaboration reflects something important: Napa’s wine industry is strongest when it works together.

Agriculture is not only Napa Valley’s heritage,  it is a cornerstone of the region’s economy and community. Agriculture generates more than $11.7 billion in economic benefit for Napa County and supports nearly 72 percent of the local workforce.

Yet growers and wineries today operate within an increasingly complex regulatory environment. Federal and state regulations already shape nearly every aspect of farming and land stewardship. When local processes become outdated or unnecessarily burdensome, they can create delays and challenges not only for growers but also for county staff and the broader community.
​
The joint recommendations aim to address these issues constructively while maintaining the values that have defined Napa Valley since the establishment of the Agricultural Preserve nearly 60 years ago.

The organizations’ recommendations focus first on practical improvements that can streamline processes and update outdated policies. These include:

• Updating the county’s interpretation of AB 720 to include vineyards located on winery parcels
• Removing the outdated “By Appointment Only” winery sign requirement
• Allowing administrative approval for minor marketing plan changes that do not increase visitor intensity
• Establishing clearer processes for incomplete permit applications to reduce delays
• Streamlining review of minor or CEQA-exempt project changes
• Recalibrating groundwater management fees to better reflect realistic program costs
• Updating baseline tree canopy metrics and encouraging flexible mitigation strategies
• Reforming the appeals process, including fee recovery for prevailing parties and transparency around parties in interest

​These recommendations are intended to make local processes more efficient while preserving the core protections that safeguard Napa’s agricultural lands.

In addition to immediate policy updates, the joint document outlines broader priorities for Napa County’s upcoming General Plan update and long-term land use planning.
Among the shared goals:

• Maintaining the 75% Napa grape sourcing requirement
• Protecting agricultural zoning and minimum parcel sizes
• Reinforcing urban growth boundaries
• Ensuring Right to Farm protections
• Recognizing vineyards as part of wildfire resilience and landscape stewardship
• Supporting the processing and sale of Napa-grown agricultural products

​These priorities reflect the wine industry’s commitment to maintaining Napa Valley as a working agricultural landscape.

This collaboration will culminate in a joint presentation during public comment at the April 28 meeting of the Napa County Board of Supervisors, where representatives from all four organizations will formally introduce the recommendations and encourage thoughtful dialogue about the path forward.
​
Industry leaders, growers, and community members are encouraged to participate and lend their voices in support of a resilient agricultural future.

​By working collaboratively, Napa’s agricultural organizations are demonstrating that thoughtful engagement with local government can strengthen both the industry and the community it serves.
​
For NVG and its partners, this effort represents something larger than a single policy discussion. It is a commitment to ensuring that Napa Valley remains a thriving agricultural region, today and for generations to come.
