California Code, Harbors and Navigation Code - HNC § 7080

(a) Except for the first election, directors shall be elected at general district elections.  All other elections are special district elections.  The first general district election shall be held on the same day as and shall be fully consolidated with the next statewide direct primary which is held more than six months subsequent to the formation of the district and succeeding general district elections shall be held on the same day and shall be fully consolidated with the succeeding statewide direct primaries.

(b) No notice of a general district election need be given.  The precincts, polling places and election officers shall, within the district, be the same as those provided for the statewide direct primary and the elections shall be held in all respects as if there were only one election and only one form of ballot shall be used unless some precincts are not entirely the same for both elections, in which case separate ballots may be provided as necessary.

(c) The district shall pay to the county the actual cost of the services rendered in conducting the election upon presentation to the board of a properly approved bill from the county.  The returns shall be canvassed by the county officer or officers required to canvass the returns of the statewide direct primary and a certificate stating the result of the canvass shall be filed with the board who shall declare the result and declare elected the persons having the highest number of votes given for each office.

(d) The certificate shall be retained in the district records and the results and declaration shall be entered on the minutes of the board.  The secretary shall deliver to each person elected a certificate of election signed by the secretary and authenticated with the seal of the district.
