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 the regulations or restrictions thereunder or applicable thereto. Any proposed amendment, supplement, change, modification or repeal shall first be submitted to the Planning and Zoning Commission for its recommendations and report.

The Commission shall be convened by its Chairman, and shall make a study of the proposed amendment, supplement, change, modification or repeal and in its study and deliberations shall take into consideration and base its findings and recommendations in accordance with the City plan and regulations designed to lessen congestion in the streets; to secure safety from fire, panic and other dangers; to promote health and the general welfare; to provide adequate light and air; to prevent the overcrowding of land; to avoid undue concentration of population; to preserve features of historical significance; to facilitate the adequate provision of transportation, water, sewerage, schools, parks, and other public requirements with reasonable consideration, among other things, to the character of the district and its peculiar suitability for particular uses, and with a view to conserving the values of buildings and encouraging the most appropriate use of land throughout the municipality. It shall give consideration to regulating and restricting the height, number of stories and size of buildings and other structures, the percentage of lot that may be occupied, the size of yards, courts and other open spaces, and the location and use of buildings, structures and land within the City.

The Commission shall submit its report to the Board of Aldermen within sixty (60) days. If the Commission fails to submit its report within that period the Board of Aldermen shall consider the matter as though submitted to it by the Commission without recommendation. The Board of Aldermen shall hold a public hearing in relation to any amendment, supplement, change, modification or repeal but not before first receiving the report of the Commission and after at least fifteen (15) days' notice of the time and place of the hearing published in a newspaper having general circulation in the City of Clarkson Valley.

In case of an adverse report by the Planning and Zoning Commission, or if a protest against such proposed amendment, supplement, change, modification or repeal shall be 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, places and alleys) included within such proposed amendment, supplement, change, modification or repeal, 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, supplement, change, modification or repeal shall not become effective except by the favorable vote of two-thirds (2/3) of all members of the Board of Aldermen.

Before any action shall be taken as provided above, except when proposed by the City on its own motion, the party or parties proposing or recommending a change in the district boundaries or regulations shall file with the City Clerk a written petition with the proposed or recommended changes and shall deposit with the City the sum of one hundred fifty dollars ($150.00) to cover the approximate cost of this procedure and under no condition shall said sum or any part thereof be refunded for failure of said change to be adopted by the Board of Aldermen.

Should it subsequently be determined by the Board of Aldermen that a public hearing is required, before proceeding with such public hearing, petitioner shall be required to deposit the additional sum of three hundred fifty dollars ($350.00), to cover the approximate cost of such public hearing. If for any reason the public hearing is not held, the three hundred fifty dollar ($350.00) deposit, less any expenses incurred by the City, shall be refunded to petitioner. If the public hearing is held, then under no condition shall said sum or any part thereof be refunded for failure of said change to be adopted by the Board of Aldermen. The City may charge an additional fee if the cost of the administrative hearing exceeds the amount deposited by the petitioner.
