Following each decennial census, the Board of Supervisors is required to reestablish supervisorial districts that are substantially equal in population based on data from that census. The current supervisorial districts were established by Ordinance No. 2011-15, which the Board of Supervisors adopted on August 9, 2011, after the 2010 decennial census. Ordinance No. 2011-15 is codified at Article 24-2.2 of the County Ordinance Code and identifies each whole and partial census tract within each supervisorial district.
In accordance with Elections Code section 21500, et seq., and other applicable legal requirements, the Board of Supervisors is undertaking a public process to determine how supervisorial districts will be reestablished following the 2020 decennial census to ensure they remain substantially equal in population. Assembly Bill 594 (Stats. 2021, Ch. 320, § 2), urgency legislation that became effective on September 27, 2021, amended Elections Code section 21500(a) to authorize county boards of supervisors to reestablish supervisorial districts by resolution.
Establishing supervisorial districts by resolution will allow for a longer process of public engagement. A resolution will need to be adopted by December 15, 2021, in accordance with Elections Code section 21501(a)(2). The resolution will need to identify each whole and partial census tract within each supervisorial district.
If the Board of Supervisors introduces Ordinance No. 2021-35, the Board would be able to consider adopting Ordinance No. 2021-35 at its next regular meeting on November 9, 2021. The adoption of Ordinance No. 2021-35 on November 9, 2021, will ensure a seamless transition to new supervisorial districts. Ordinance No. 2021-35 would provide that the repeal of the existing supervisorial districts will become operative on the operative date of a resolution establishing new supervisorial districts.
