Zoning
A-1
Agricultural District
The purpose of this district is to provide for a full range of agricultural activities and to protect agricultural land, as one of the county's most valuable natural resources, from the depreciating effect of objectionable, hazardous, and unsightly uses. The district is also intended for protection of watersheds, water resources, forest areas, and scenic values, and at the same time to provide for spacious residential development for those who choose this environment and to prevent untimely scattering of more dense urban uses which should be confined to areas planned for efficient extension of public service.
Permitted uses

Agriculture
Equestrian facility
Greenhouse / nursery
