Agricultural Rural District

The purpose of this district is to provide for continued farming activity and the many uses that do not require public water and sewerage facilities and which may be more suitably located outside of the urban-type growth of the larger communities of the County. The Agricultural zoning district has been purposely drawn to enclose large blocks of the best soils for intensive agricultural production as well as gently rolling topography for farming. Most of the operating farms as well as the largest block of farmland preserved through the Agricultural Preservation Program is located in this area.

Permitted uses

Include but are not limited to:

Agriculture
Equestrian facility
Greenhouse / nursery
Religious facility
Day care facility
Housing-Single unit
Housing-Multiple units
Manufacturing
Public service
