R-10
Residential District 10
The purpose of the Residential District is to allow for a range of residential densities. The primary use shall be detached residences. Other types of dwellings may also be allowed, including zero lot line, cluster and common wall housing arrangements. Nondwelling uses that support and complement residential neighborhood activities shall also be permitted. The intent of the R-10 districts is to provide areas for large lot developments. These areas would be located typically at the outskirts of urban development and may be applied as a transitional district between preservation, agricultural or country districts and urban districts. They would also be applied to lands where residential use is desirable but some development constraints are present.
