§ 13.1. Action by planning and zoning commission.

The regulations, restrictions and boundaries set forth in this ordinance may from time to time be amended, supplemented, changed or repealed. Provided, however, any proposal to amend, supplement, change or repeal this ordinance shall first be made to the planning and zoning commission which, after considering the same, upon the affirmative vote of a majority of those present and voting at a meeting thereof may make a preliminary report thereon, conduct a public hearing with respect thereto and, at the conclusion of such public hearing, make a final report to the city council recommending the acceptance or rejection of such proposal. Provided, however, if the proposal to amend, supplement, change, or repeal this ordinance is referred to the planning and zoning commission by the affirmative vote of the majority of the members of the city council present and voting at any meeting thereof, then the planning and zoning commission shall be obligated not only to consider the same but to make a preliminary report thereon, conduct a public hearing with respect thereto and, at the conclusion of such public hearing make a final report to the city council recommending the acceptance or the rejection of such proposal. At least 15 days' notice of the time and place of the public hearing hereinabove provided for shall be published in a newspaper of general circulation in the city. When any proposal constitutes a proposed change in classification, written notice of such public hearing shall be sent to the owner of all real property lying within 200 feet of the property on which the change in classification is proposed, such notice to be given, not less than ten days before the date set for hearing, to all such owners who have rendered their said property for city taxes as the ownership appears on the last approved city tax roll. Such notice may be served by depositing the same, properly addressed and postage paid, in the city post office. Where property lying within 200 feet of the property proposed to be changed is located in territory which was annexed to the city after the final date for making the renditions which are included on the last approved city tax roll, notice to such owner shall be given by publication in the manner provided above.
