The Board of Aldermen 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. Any proposed amendment, supplement, change, modification, or repeal of these zoning provisions shall first be submitted to the Planning and Zoning Commission upon forms prescribed for that purpose by the Planning and Zoning Commission and accompanied by such data and information so as to assure the fullest practicable presentation of facts, for its recommendations and report. If the Commission makes no report within sixty (60) days, it shall be considered to have made a report approving the proposed amendment, supplement, modification, or change. Upon the filing of the recommendations and report by the Commission with respect to any proposed amendment, supplement, change, modification, or repeal, the Board of Aldermen shall proceed to hold a public hearing in relation thereto, giving at least fifteen (15) days' notice of the time and place of such hearing, which notice shall first be published in a newspaper having a general circulation in the City of Union. The Zoning Enforcement Official or his designated representative shall post a notice of public hearing in a conspicuous place on said property at least 15 days prior to said hearing on each side of a property fronting on a street or highway. In addition, notice shall be sent by registered mail to all property owners within three hundred (300) feet of the property proposed to be rezoned.

If a protest against such change, modification, or repeal was presented in writing to the City Clerk duly signed and acknowledged by the owners of thirty percent (30%) or more, either of the area of the land (exclusive of streets, and alleys), included within such proposed change, or within an area, determined by lines drawn parallel to and one hundred eighty-five (185) feet distant from the boundaries of the district proposed to be changed, such amendment shall not become effective except by the favorable vote of two-thirds (2/3) of all the members of the Board of Aldermen.

The party or parties other than the Board of Aldermen proposing or recommending a change in the district regulations or district boundaries or requesting a rezoning shall deposit five hundred dollars ($500.00) with the City Clerk at the time the application is submitted and shall be provided a receipt therefore. All deposits received hereunder shall be paid over to the credit of the General Revenue Fund of the City of Union. The deposit shall be used for all expenses associated with the proposed rezoning or regulation change to specifically include, but not necessarily limited to, all costs for notice and publication, staff time associated with processing the request, postage for any recording of any documents and all mailings required and any other expenses pertaining directly thereto. Any balance remaining after deducting for all expenses shall be refunded to the party or parties who made the deposit. In the event the expenses associated with the application are more than the deposit, the City Clerk shall cause a statement for the balance to be sent to the applicant for immediate payment. The City Clerk shall cause no action to be taken regarding the decision until the balance has been paid.
