A retail transactions and use tax ordinance shall be imposed by the authority in accordance with Section 150206 and Part 1.6 (commencing with Section 7251) of Division 2 of the Revenue and Taxation Code, if a majority of the electors voting on the measure vote to approve its imposition at special elections called for that purpose by the county and city, respectively. Those elections shall be consolidated. The ordinances shall take effect at the close of the polls on the day of election at which the measures are adopted, to impose the tax at the same rate.

The initial collection of the retail transactions and use tax shall take place in accordance with Section 150204.

If, at any time, the voters do not approve an ordinance imposing the retail transactions and use tax, the same or a different measure imposing that tax may, at any time thereafter, be submitted to the voters.
