(1) Procedures. Whenever any person, firm or corporation desires that any amendment or change be made in this chapter, including the text and/or map, as to any property in the city and there shall be presented to the city council a petition requesting such change or amendment and clearly describing the property and its boundaries as to which the change or amendment is desired, duly signed by the owners of 50 percent of the area of all real estate included within the boundaries of said tract as described in said petition, and in addition duly signed by the owners of 50 percent of the area of all real estate lying outside of said tract but within 250 feet of the boundaries thereof, it shall be the duty of the city council to vote upon such petition within a reasonable time after the filing of the petition.

Prior to voting or holding a public hearing upon the petition as submitted, the city council shall refer the petition to the Ida Grove zoning commission requesting their comments and recommendations. The commission, after public hearing, shall advise the city council of their recommendations and the vote thereon.

In case the proposed amendment, supplement or change be disapproved by the Ida Grove zoning commission, or a protest be presented duly signed by the owners of 20 percent or more of the area included in such proposed change or of the area immediately adjacent thereto and within 250 feet of the boundaries thereof, such amendment shall not become effective except by the favorable vote of at least 60 percent of all members of the city council. Whenever any petition for amendment, supplement or change of the zoning districts or regulations herein contained or subsequently established shall have been denied by the city council, then no new petition covering the same property or the same property and additional property shall be filed with or considered by the city council until one year shall have elapsed from the date of the filing of the first petition. Amendments to any floodplain district or related provisions shall be approved first by the Natural Resource Council and notification given to the Federal Insurance Administration.

(2) Filing Fees. Before any action shall be taken as provided in this chapter, the owner or owners of the property proposed or recommended to be changed in the district regulations or district boundaries shall pay to the city the sum of $60.00 to cover the costs of the procedure. Under no conditions shall said sum or any part hereof be refunded for failure of said amendment to be enacted into law. [Ord. 437 § C, 1994; Code 1975 § 6-5.0708.]
