The Board of Mayor and Aldermen may, from time to time, on its own motion or on petition from a property owner or on recommendation of the Planning and Zoning Commission, amend the regulations and districts herein established. All amendments shall be forwarded to the Planning and Zoning Commission for its review, comments and recommendations to the Board of Mayor and Aldermen for its consideration.

No change in regulation, restrictions or district boundaries shall become effective until after a public hearing is held by the Planning and Zoning Commission, at which time interested agencies and citizens shall have an opportunity to be heard. At least fifteen (15) days' notice of the time and place of such hearing shall be published in an official newspaper or newspaper of general circulation in Hancock County, Mississippi.

The Planning and Zoning Commission may recommend to the Board of Mayor and Aldermen to attach reasonable special conditions to the approval of any amendment to ensure that there will be no departure from the intent of this Zoning Ordinance.

Each amendment shall be voted upon in accordance with local ordinances or state statutes except in a case of a protest against such change. If a protest against such a change is presented and is signed by the owners of twenty (20%) percent or more, either of the area of lots included in such proposed change, or of those within a radius of one hundred sixty (160) feet of the external boundaries of the area in such proposed change, such amendments shall not become effective except by the favorable vote of three-fifths (⅗) of all members of the Board of Mayor and Aldermen of the City of Waveland, Mississippi.
