Before taking action on any proposed amendment, supplement, or change, the City Council shall submit the same to the Planning and Zoning Commission for its recommendation and report. The Planning and Zoning Commission shall hold a public hearing on any application for any amendment, supplement, or change prior to making its recommendation and report to the City Council. Written notice of all public hearings before the Planning and Zoning Commission on a proposed amendment, supplement, or change to a zoning district boundary shall be sent to all owners or persons rendering taxes on real property lying within two hundred (200) feet of the property for which the change is requested. Such notice shall be given not less than ten (10) days before the date set for hearing by depositing a notice properly addressed and postage paid in the United States Post Office to such property owners as their ownership appears on the last approved city tax roll.
