The purpose of the Zoning Ordinance is to ensure sound land management and orderly development of the City. It regulates the types of uses that can occur in each zoning district as well as the specific development standards for each zoning district, which control such details as lot sizes and height, size, and use of buildings. The district boundaries are depicted on the City's Zoning Map. The City's Zoning and Subdivision Ordinances are periodically reviewed and revised in order to implement the City's Comprehensive Plan or in response to requests for changes in zoning. Such revisions and requests are reviewed by the Planning Commission and acted on by the City Council after a public hearing.
