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.
