A. The provisions set forth in this title may, from time to time, be amended, supplemented, changed, modified or repealed by action of the city board or when such amendment, supplement, change, modification, or repeal is requested through a petition not exceeding sixty (60) percent of the landowners in the aggregate area requesting change. An individual landowner may also petition the city council to change the zoning of all or any part of his or her property. Upon filing or upon separate request by the city board, or the city planning commission and the city board, the city planning commission and the city board shall hold a public hearing not less than fifteen (15) days after notice is published in the official city newspaper and subject to the provision of SDCL 11-4-8 and 11-4-9. Such petitioning landowner shall also notify all other abutting landowners by registered mail of the petitioned zoning change at least one week prior to any public hearing held on the petitioned zoning change by the city planning commission.

B. The city planning commission shall within thirty (30) days make its recommendation to the city board. The report of such recommendations shall include approval, disapproval or other suggestions and the reasons therefor, and a discussion of the effect on such amendment, supplement, change, modification upon adjacent property and upon the comprehensive plan.

C. The city board shall therefore, by duly enacted ordinance, either adopt or reject such amendment, supplement, change, modification or repeal; and if it is adopted by the city board after proper notice, the ordinance shall be published in the official newspaper in the city and take effect on the twentieth day after its publication.
