About the Board

The Board of Supervisors is the governing body of Napa County, with jurisdiction that varies depending on the services. The Board has jurisdiction over land use, roads and municipal services in the unincorporated areas of the county. For other services, such as Corrections (Jail), Health and Human Services, document recording, etc., the Board's jurisdiction is countywide.

The five members of the Napa County Board of Supervisors are elected by voters in five Supervisorial districts. They serve four-year terms, and the Chair of the Board is rotated among the members by District. The 2020 chair is District 3 Supervisor Diane Dillon.

In order to clearly articulate the basic assumptions and beliefs that the Board of Supervisors uses to guide their decision-making, the Board has agreed on a mission, vision and core values.

Each Napa County employee, service, program, division and department strives to adhere to these same mission, vision and values.

Twice a year, the Board holds planning retreats to revisit their three-year goals, and ensure that they remain valid and relevant.
