Sonoma County, California, is a special place. Its environments range from the surf-pounded cliffs of the coast to the golden Mayacamas Mountains, from the cool stillness of redwood forests to the muddy marshes that feed San Francisco Bay. From the vineyards of the Alexander Valley to high-tech Telecom Valley, the economy is strong and equally diverse.

This informational brochure offers an overview on the County of Sonoma, including population characteristics, environment, and the various services and facilities provided to citizens.

County government functions as a local government body to serve the needs of its residents. As geographical and political subdivisions of the State, counties serve a dual role, providing municipal services in unincorporated areas and acting as administrative agents for state and federal government programs and services. As a general-law county, Sonoma County is bound by state law as to the number and duties of county elected officials. Districts that are approximately equal in population elect members of the Board of Supervisors. Boundaries are adjusted every ten years following the federal census.

The Board of Supervisors
The Board of Supervisors establishes policies and sets priorities for all activities within its jurisdiction.  In addition, they oversee the functions and activities of the many branches of county government that provide county-wide service including health and welfare programs, elections, and public protection programs.  The Board of Supervisors also acts as the governing body that provides municipal services to the unincorporated areas of the county such as fire protection and law enforcement, land use regulations, road maintenance, parks, and lighting and water utilities.

The County Administrator
e Board of Supervisors appoints the 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 in county government operations.
