Rural Village District

The Rural Village designation is provided to preserve the unique historic or rural character of existing villages by encouraging compatible development within a defined village boundary. It also identifies clusters of existing development in the rural areas that may be candidates for public facilities in the future. The zone intends for permitted development to be generally of a similar density, scale and use type and mixture as that which exists in the village. The zone is also designed to prevent large amounts or inappropriately scaled development or uses that would detract from the existing rural or historic character of the village. It is expected that development will be residential and a limited amount of mixed rural services. More than one use may be permitted on one parcel in accordance with specific guidelines. Public water and sewer may be available for the purpose of resolving or preventing health issues. Use of public utilities to permit greater density than the density specified in this section is not permitted.

Permitted uses

Include but are not limited to:

Agriculture
Equestrian facility
Greenhouse / nursery
Religious facility
Day care facility
Housing-Single unit
