California Code, Elections Code - ELEC § 1302.2

(a) Notwithstanding any other provision of law, when an elementary, unified, high school, or community college district includes within its boundaries the same territory, or territory that is in part the same, as a chartered city, the governing board member elections of the elementary, unified, high school, or community college district may be consolidated with the city election pursuant to Part 3 (commencing with Section 10400) of Division 10.  The consolidation shall be effected by the officer conducting the election having jurisdiction of the elementary, unified, high school, or community college district, upon the written request of the governing board of the elementary, unified, high school, or community college district and with the written consent of the legislative body of the city.  This section shall control in the event of any conflict with a prior order of the county superintendent of schools made pursuant to Section 5340 of the Education Code.

(b) When a high school district or community college district election is consolidated with that of a city pursuant to this section, and the high school district or community college district has within its boundaries component districts whose elections would otherwise be held on a date specified in this code, the elections in the component districts may be consolidated with the election in the high school district or community college district.  The consolidation shall be effected by the officer conducting the election having jurisdiction of the component districts upon the written request of the governing boards thereof and with the written consent of the governing boards of the districts whose governing board member elections are to be consolidated with those of the component districts.

(c) Successors to incumbents holding office upon the effective date of this section, who in the absence of this section would have been elected at a different time, shall be chosen for office at the election nearest the time the terms of office of the incumbents would have otherwise expired.  If an incumbent's term of office is extended because of this section, he or she shall hold office until a successor qualifies for the office, but in no event shall the term of an incumbent be extended to more than four years.
