Sonoma County Administration BuildingThe Sonoma County Board of Supervisors sits as the governing board of Sonoma County and of various special jurisdictions such as the Sonoma County Water Agency, the Northern Sonoma County Air Pollution Control District, the Agricultural Preservation and Open Space District, County Sanitation Districts, and the Community Development Commission. The Board is composed of five supervisors elected from supervisorial districts for four year terms.

If you do not know which supervisor represents your area, contact the Office of the Registrar of Voters at (707) 565-6800 and they can tell you.

The Board normally holds its regular meetings on Tuesdays, beginning at 8:30 a.m. A consent calendar involving routine financial and administrative actions, usually approved by a single majority vote, is normally heard first. A regular calendar with more significant items of special interest follows the consent calendar. The afternoon calendar begins at 2:00 p.m. with Public Comment on Issues not on the Agenda where the public can address the Board on any issue that concerns them. That is followed by public hearings related to a variety of issues such as leases, land use decisions, fees, and vacations of roads.

The Board of Supervisors meets in the Board of Supervisors Chambers at 575 Administration Drive, Room 102A, Santa Rosa, California. The phone number is (707) 565-2241 and the fax number is (707) 565-3778. Any member of the audience may address the Board on a matter on the agenda, within time limits at the discretion of the Chair or the Board. Copies of the agenda are available at the Office of the Clerk of the Board of Supervisors (Room 100A), and also at Public Libraries, Chambers of Commerce, and City Halls throughout the County.
