Cal. Harb. & Nav. Code § 7216

If from the election returns it appears that more than two-thirds of the votes cast upon the measure were in favor of and assented to the incurring of the general obligation bonded indebtedness, then the board may, by resolution, at the time or times it deems proper, issue bonds of the district for the whole or any part of the amount of the indebtedness so authorized, and may from time to time provide for the issuance of such amounts as the necessity thereof may appear, until the full amount of the bonds authorized shall have been issued.
