Our Governing Boards

The Board of Supervisors

The Board of Supervisors is comprised of five members, one from each of the five districts, elected to four-year terms. The Board establishes policies concerning growth and development, and sets priorities for all activities within the county. In addition, they oversee the many departments and agencies of county government that provide county-wide services, health and welfare programs, elections, and public safety programs. The Board of Supervisors is also the governing body that provides municipal services to those unincorporated areas outside of cities.

The County Administrator

The Board of Supervisors appoints County Administrator who assists the Board in managing, directing and coordinating the operations of all county departments. The County Administrator also prepares the county budget and makes recommendations to the Board to promote economy and efficiency within the county.

    Published on August 7, 2018

    Sonoma County voters this fall will have the opportunity to create a dedicated source of funding for their Regional and city parks. The Board of Supervisors agreed Aug. 7 to place a 1/8-cent sales tax for parks on the November ballot. If approved by voters countywide, the measure will help the county and cities maintain parks, reduce wildfire risks, protect waterways and wildlife, open long-awaited parks, expand trails, and offer programs. A key piece of the measure is an expenditure plan that details how the funding will support parks.
