If a proposed change to a regulation or boundary receives written protest, being signed by the owners of at least 20 percent of the area of the lots or land covered by the proposed change, or the area of the lots or land immediately adjoining the area covered by the proposed change and extending 200 feet from that area, then a three-fourths affirmative vote of all the members of the City Council shall be required in order to take effect. In computing the percentage of land under protest, the area of streets and alleys shall be included. Additionally, an affirmative vote of at least three-fourths of all members of the City Council is required to overrule a recommendation of the Planning and Zoning Commission that a proposed change to a regulation or boundary be denied in order for the change to take effect.

The Official Zoning Map of the City shall be kept in the City Planning Department, and all changes in district boundaries shall be noted thereon immediately after approval by the City Council.

In those circumstances where a request for a change in zoning or a request for approval of a Special Use Permit is denied by the Governing Body there may be no other submittal for approval for the same property until a period of 12 months has passed. An exception may be granted to this provision for applications that have undergone substantial change. Substantial change is evidenced by the addition of a buffer area between the applicant and adjacent properties or the requested zoning classification has been changed from the original application. Additionally, a formal request can be made to the Planning and Zoning Commission to determine whether the application has substantial change and warrants being rescheduled for the Commission at a follow-on meeting. Requests for determinations of substantial change will be listed as individual agenda items for the Commission. This request must occur at a meeting separate from the hearing for approval.
