The city council may from time to time, on its own motion or on petition, amend, supplement, change, modify or repeal by ordinance the boundaries of districts, or regulations or restrictions established in this title. Any proposed amendment, supplement, change, modification or repeal shall first be submitted to the city plan commission for its recommendation and report. If the city plan commission makes no report within thirty days, it shall be considered to have made a report approving the proposed amendment, supplement, modification or change. After the recommendations and report of the city plan commission have been filed, the city council shall before enacting any proposed amendment, supplement, change, modification or repeal, hold a public hearing in relation thereto, giving at least ten days' notice of the time and place of such hearing, by one publication in a newspaper having a general circulation in the city.

(Ord. 1411 § 1, 1985)

If the city plan commission recommends against or if a protest against such proposed amendment, supplement, change, modification or repeal is presented in writing to the city clerk duly signed and acknowledged by the owners of twenty percent or more, either of the area of the lots included in such proposed change or of those immediately adjacent in the rear thereof extending the depth of one lot or not to exceed two hundred feet therefrom or those directly opposite thereto, extending the depth of one lot or not to exceed two hundred feet from the street frontage of such opposite lots, such amendment, supplement, change, modification or repeal shall not become effective except by the two-thirds vote of all the members of the city council.

(Ord. 986 (part), 1965: prior code § 26-25.1)

Before any action is taken as provided in this chapter, the party or parties proposing or recommending a change in the district regulations or district boundaries shall deposit with the city clerk the sum of one hundred fifty dollars to cover approximate cost of this procedure, and under no condition shall the sum or any part thereof be refunded for failure of the change to be adopted by the city council.
