The council may by means of an ordinance submit a proposition for the repeal or amendment of an ordinance, initiated by petition, by submitting it to a vote of the people at any general election and if a majority of the votes cast upon the proposition favor it, the ordinance shall be repealed or amended accordingly.

A proposition of repeal or amendment must be published before the election thereof as in an ordinance initiated by petition when submitted to election. (Ord. 2230 § 20, 1975.)
