Upon receipt of the certified copy of a proposed ordinance from the committee of the petitioners the City Clerk shall certify that fact to the Council at its next regular meeting. If any election is to be held not more than one year nor less than thirty days after the receipt of the Clerk's certificate by the Council, the proposed ordinance shall be submitted to a vote of the electors at the first such election unless the Council provide for submitting it to the electors at a special election to be held within the time aforesaid. If no other election is to be held within one year and not less than thirty days after the receipt of the Clerk's certificate as aforesaid, the Council may provide for submitting the proposed ordinance to the electors at a special election to be held within that time. If, when submitted to the electors, a majority of those voting on a proposed ordinance vote in favor thereof, it shall be an ordinance of the City. Initiated ordinances adopted by the electors shall be published, and may be amended or repealed by the Council, as in the case of other ordinances.
