Zoning

A-1

Agricultural District

The A-1, Agricultural Zoning District is intended to implement the agricultural or estate classification of the Comprehensive Plan. The district is designed to encourage conservation and proper use of large tracts of real property in order to assure available sources of agricultural products, to assure open spaces within reach of concentrations of population, to conserve natural resources, prevent erosion, and protect the environment; and to assure adequate water supplies. The intent is to encourage private land owners to protect these values and thereby create an environment favorable for the continuation farming and other agricultural pursuits; to preserve prime agricultural land, forest land and/or open space; and to reduce the demand for costly public facilities and services that are inconsistent with the character of the rural areas within Prince William County.
