Last Tuesday, Napa County supervisors spent a sizable portion of their meeting wrestling with a confidential legal deal tied to Arrow&Branch winery. By the end, they had debated and provisionally accepted a settlement meant to resolve an appeal by watchdog group Water Audit California over the winery's already approved expansion.
The board voted unanimously to tack on extra conditions to the project, including more frequent monitoring of the winery's well and additional requests for data disclosure. Supervisors also attached two clear caveats: the new conditions are not supposed to set a precedent for future projects, and county staff must first receive and review the full, amended settlement before the expansion can legally move forward.
The modification approved earlier by the Planning Commission would boost Arrow&Branch's annual wine production from 30,000 to 45,000 gallons, expand tasting and marketing activities, and add several building additions, as well as an approximately 81,000-gallon process water storage tank. Those project details are laid out in the CEQA filing on CEQAnet.
What The Settlement Reportedly Says
According to a copy of the agreement reviewed by the Napa Valley Register, the confidential settlement reportedly requires more frequent reporting of well data to the county and includes a $25,000 payment from Arrow&Branch to Water Audit California. The secrecy around the deal, combined with the board's decision to tie county approvals to an agreement the public has not seen, raised transparency concerns during the hearing.
How The Board Framed Its Vote
County meeting minutes state that supervisors voted unanimously to approve revised conditions for the project, added language clarifying that the changes are not precedent-setting, and made final approval contingent on the county receiving the full, amended settlement first. The motion and vote are recorded in the Napa County Board of Supervisors minutes, which summarize presentations from planning staff, the applicant's attorney, and the appellant's representative before the board acted according to Napa County
What Water Audit Pushed For
Water Audit California, which filed the appeal, argued that the county review did not adequately demonstrate that pumping from the winery's well would avoid harming Dry Creek. The group pressed for more robust monitoring and public reporting of well data. On its website, the organization has posted technical comments and a description of its appeal, characterizing the dispute as implicating watershed and public-trust concerns as per Water Audit California.
Neighbors, Location Questions And A Winery With History
Neighbors near the project raised alarms about both the scale and location of the new buildings, flagging the expansion's proximity to homes on Darms Lane. Resident Bill Falk spoke to the board on behalf of nearby property owners, questioning whether the winery had actually been constructed at the precise location approved.
The Contursis family purchased the parcel in 2020 to use an earlier 2013 approval and opened Arrow&Branch in 2024. That history has helped fuel scrutiny of the expansion, as reported by the Napa Valley Register.
What Happens Next
The county's recap and agenda indicate that supervisors left the matter for a later meeting and that final actions are contingent on receipt of the settlement. Follow-up items and any required monitoring are scheduled for review at the next hearing. Until the full agreement is filed with the county and the monitoring terms are folded into public records, the expansion will remain subject to additional administrative steps.
Why Locals Are Watching
The dispute highlights a recurring tension in Napa County politics: wineries seeking to scale up operations versus neighbors and environmental advocates demanding stringent safeguards for groundwater and streams. Supervisors described their move as an effort to avoid quietly rewriting county policy while still locking in short-term protections and keeping both sides out of drawn-out, costly litigation.
