Cal. Pub. Util. Code § 103323

Each election shall be called and conducted by the district in the same manner as provided by law for the conduct of special elections by a county. The board may contract with the county, or delegate to the appropriate county officials the authority, to conduct the election on behalf of the district. The costs of any such election may be advanced to the district by the county prior to the time that the district has revenues of its own, to be repaid from subsequent district revenues.
