CA Elec Code Section 10402.5

Any state, county, municipal, district, and school district election held on a statewide election date pursuant to Section 1002 shall be consolidated with the statewide election pursuant to this part except that, in counties of the first class, the board of supervisors may deny any request for consolidation if it finds that the ballot style, voting equipment, or computer capacity is such that additional elections or materials cannot be handled. The procedural requirements prescribed for that type of election shall be construed as if this section were specifically set forth in the provisions relating to that election.
