Excerpts: Rural zoning is one of the many tools that county and community planning committees can sometimes employ effectively to help improve land use conditions within the county. Zoning is largely a preventive measure. Even in the places where it can operate most successfully, it should always be used in conjunction with other tools for assisting adjustments in land use. Rural zoning provides a way in which a county, by adopting a local ordinance, can guide the location of new settlers and prevent the further expansion of undesirable land uses that are now occurring in the county or in parts of it. A rural zoning ordinance does not stop anyone from continuing the undesirable uses of land that were begun before passage of the ordinance, or from continuing to live on his farm. It simply bars new persons from undertaking the specified undesirable uses, or from establishing new homes in isolated areas. Zoning, used by itself, causes no immediate improvements in land use, and is, therefore, a rather negative measure. When used along with measures such as public land purchase, relocation of stranded families, adjusted credit policies, and other devices, however, rural zoning often may give outstanding assistance in a county’s efforts to bring about better land use and a better life for its people.
