Cal. GOV § 6546.4

The governing body of any local agency adopting an ordinance pursuant to Section 6546.3 shall call an election for purposes of submitting to the qualified electors of the agency the question of whether the ordinance shall be adopted. Such election shall be called, held, conducted and the votes canvassed in the same manner, or as near thereto as is possible, as an election at which the local agency submits a general obligation bond proposal to its voters.

For purposes of this section the voters of the local agency shall be the voters entitled to vote at elections for members of the governing board of the agency, if the agency has an elected governing board, and the vote of each such voter shall be given the same weight as it would be given in an election for members of the governing board. If a local agency does not have an elected governing board, the voters of the agency shall be the voters residing within the boundaries of the agency who would be qualified to vote for candidates for Governor at any gubernatorial election. If a majority of the votes cast within a local agency are for adoption of the ordinance, the ordinance shall be deemed adopted; provided, however, that the ordinance shall not take effect until a certified copy of the record of the final canvass of votes is filed with the Secretary of State.

If a local agency does not have statutory power to introduce an ordinance and submit it to the voters of the agency, the governing body of such local agency may introduce and submit such ordinance at any regular meeting by the approving votes of a majority of all of its members.
