A. An amendment proposing changes in the official zoning map shall follow substantially the same procedures as provided for in Section 18.12.020 with the following additional requirements to be met:

1. The applicant shall provide names and addresses of all property owners within one hundred fifty feet of the proposed amendment area.

2. The application for amendment shall be signed by an owner of record or his authorized agent in the space provided on the application.

3. In the event that an application filed by a real property owner in the area involved includes any property other than owned by the applicant, then before the application will be accepted for processing, a petition in favor of the request signed by the real property owners representing at least sixty-five percent of the land area to be included in the application must be submitted. Said petition shall bear the property owners’ signatures and addresses, the legal description and land area of each property represented in the petition, the total land area represented by the petition, and the percentage of land area of the amendment area owned by the petitioners in total and individually.

4. The staff of the planning board shall mail a notice to all property owners included in the proposed amendment area and all property owners adjacent to and within one hundred fifty feet of the boundary of the proposed amendment area. (Where the subject property abuts a public right-of-way, the one hundred fifty foot measurement shall be in addition to the right-of-way along the abutting sides.) Such notice shall be made no less than fifteen days prior to the planning board hearing date.

5. In the event that a written protest against a proposed amendment is filed in the office of the zoning administrator no later than ten days following planning board action by the owners of twenty-five percent or more, either of the area of the lots included in the proposed change or those lots within one hundred fifty feet of a lot included in a proposed change, such amendment shall not become effective except by the favorable vote of two-thirds of the present and voting members of the city council of the city of Columbia Falls, provided that such required number of votes shall not be less than a majority of the full membership of the council.

B. In the event that the city council grants the application to amend or rezone, they shall notify the zoning administrator of their action and he shall be responsible for updating the official zoning map. Such updating shall include the posting on the face of the official zoning map, the date and number of the ordinance amending such map.

C. In the event that an application to amend (rezone) is denied by the city council or that the application is withdrawn after the planning board hearing, the zoning administrator shall have the authority to refuse to accept another application for any similar amendment within one year from the date of the hearing of the previous application before the board.
