About Sonoma County

The County of Sonoma is comprised of 26 departments and agencies that provide a full range of services to the community. It encompasses over 1600 square miles. Sonoma County government has a history of providing excellent and responsive public service while operating under sound fiscal principles.

Sonoma County is located at the threshold between the commerce-driven San Francisco Bay Area and the spectacular beauty of northern California. The county extends over 1,500 square miles with a diverse economy that includes a world class wine region, stunning natural resources, and dozens of tourist destinations. Sonoma County is home to 493,285 people, with approximately 33 percent of the population residing in Santa Rosa. That city was also recently named as one of the nation’s “most livable communities” by Partners for Livable Communities. Residents all over Sonoma county enjoy a unique quality of life with access to cultural events, an academic community via CSU Sonoma State, economic opportunity, and low crime rates.

Governance

Sonoma County plays a dual role to residents, providing municipal services such as law enforcement and fire protection to unincorporated areas and providing the day-to-day operation of state and federally mandated programs. As a general-law county, Sonoma County abides by state laws that determine the number and duties of county elected officials. The county is divided into five districts that are approximately equal in population size. Each district has an elected Supervisor. District boundaries are adjusted every ten years following the release of federal census data.

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.
