California Code, Elections Code - ELEC § 4106

(a) Notwithstanding any other provision of law to the contrary, a governing board in the County of San Diego may adopt a resolution requiring its general district election to be held on the same day as the statewide direct primary election or the day of the statewide general election.

(b) If an election is held pursuant to subdivision (a), and the election is consolidated with another election, Part 3 (commencing with Section 10400) of Division 10 shall govern the consolidation and, if the county elections official is requested to conduct the election, Section 10002 shall apply to that election.
