On September 27, the Board of Supervisors adopted by ordinance the above district boundaries (maps) which became in effect that day. Election Code section 21506 provides that the new boundaries will be used in the first election for supervisors following the adoption of the new ordinance. A supervisor shall be elected from each district under the new boundaries for each district with the same number of the district for which an incumbent supervisor’s term will be expiring. Under the current election rotation schedule, this means that supervisors will be elected from the new Districts 1, 4 & 5 in 2012.

All residents of Yolo County are represented by all members of the Yolo County Board of Supervisors. The district in which some residents live may have changed with the update of district boundaries, and therefore may have a new Supervisor representing that district. Residents should feel comfortable contacting their new representative for assistance, the one previously representing their district or any other member of the Board of Supervisors.


California Elections Code section 21500 requires that the Board of Supervisors of a county adjust the boundaries of any or all of the supervisorial districts following each decennial federal census so that the districts shall be as nearly equal in population as possible and so that the districts are in compliance with the Federal Voters Rights Act of 1965. Districts must also comply with basic federal and state constitutional equal protection provisions.

On February 1, 2011, the Yolo County Board of Supervisors established an advisory committee to assist them in the process of updating the supervisorial districts, as required by law. Under State law, the Redistricting Advisory Committee (RAC) was required to make its recommendations to the Board of Supervisors no later than August 1, 2011. State law also required that the Board of Supervisors to adopt revised district boundaries by November 1, 2011.

The RAC held six public meetings including meetings in each of the incorporated cities. The RAC received a significant amount of input from the public during public comment at these meetings. At the final public meeting of the RAC on June 29, 2011, the committee chose three maps to recommend to the Board of Supervisors.

On September 13 and 27, 2011, the Board of Supervisors opened a public hearing to consider the recommendations of the RAC and other members of the public. Ultimately, on September 27, the Board of Supervisors adopted by ordinance one of the RAC recommended maps.
