Whenever public necessity, convenience and general welfare require, the boundaries of the zone and the overlay zones established by this title, the classification of property uses therein, or other provisions of this title may be amended as follows:

Amendments of this title and the Zoning Map which is a part hereof, may be adopted as follows:

Within 60 days after: (a) receipt of a completed application by the owner or owners of property; or (b) introduction of an ordinance by the City Council, as the case may be, the City Clerk shall set the matter for public hearing to be held not less than 10 days and not more than 60 days from the date of notice of the public hearing, with such notice being given in the manner provided in Government Code Section 65091. If the granting or denial of an amendment is subject to CEQA, the time periods for any notice, response, or action shall comply with the time frames established by CEQA, notwithstanding any time periods set forth in this section.

The City Council shall announce its decision and if the amendment is approved, shall adopt an ordinance incorporating the decision. The ordinance shall recite the facts and reasons which, in the opinion of the City Council, make the approval of the application for the amendment necessary to carry out the general purpose of this title.

At the time the ordinance becomes effective, one copy of such ordinance shall be forwarded to the applicant at the address shown upon the application.

If the amendment involves an amendment to the Zoning Map, the Department of Public Works, immediately following the effective date of the ordinance, shall cause the Zoning Map to be so modified. Copies of the modified Zoning Map shall be available to the public on request.
