California Code, Public Utilities Code - PUC § 13209

All special bond elections held in even-numbered years shall be consolidated with the direct primary or general election. All special bond elections held in odd-numbered years shall be held on the first Tuesday after the first Monday in November and may be held separately, or may be consolidated with any other election authorized by law at which the voters of the district may vote. When a special bond election is consolidated with a statewide primary or a general election, the board shall in the ordinance calling the special bond election consolidate it with the statewide primary or the general election to be held at the same time in the respective counties in which the district is located and authorize the respective boards of supervisors to canvass the returns and certify the result of the canvass to the board; it shall be the duty of the board or boards of supervisors to so consolidate the election, canvass the returns, and cause the result thereof to be properly certified to the board. If a special bond election is consolidated with any other election, the provisions of this chapter setting forth the procedure for the calling and holding of the special bond election shall be complied with, except that the ordinance calling the election need not set forth the election precincts, polling places, and officers of election, but may provide that the precincts, polling places, and officers of election shall be the same as those set forth in the ordinance, notice, or other proceedings calling the election with which the special bond election is consolidated, and shall refer to the ordinance, notice, or other proceedings by number and title, or by other definite description.
