Board Makeup
The Yolo-Solano AQMD Board of Directors is composed of four members from the Yolo County Board of Supervisors, three members from the Solano County Board of Supervisors, and one representative from each of the City Councils of Davis, Dixon, Rio Vista, Vacaville, West Sacramento, Winters, and Woodland. These 14 elected officials represent the governing bodies of the two counties and seven incorporated cities within the District. Each county and city selects its representative through its own internal process. There are no separate public elections or District-imposed term limits for Board membership. Each December, the Board elects a Chair and Vice Chair to serve one-year terms for the upcoming calendar year.
