Agricultural Zoning

Effective agricultural zoning, also known as agricultural preservation zoning, is a land management tool that encourages farming while discouraging non-agricultural land uses that are incompatible with farm operations. This form of zoning promotes agriculture uses and structures while limiting the number of non-farm uses such as dwellings and other activities that can compete for productive farmland.

This tool is most effective when it is used to protect areas where the local agricultural dominates the landscape and economy. Effective agricultural zoning is most appropriately used in the rural and agricultural landscapes, as well as in portions of natural landscapes that are being farmed.

Agricultural areas on prime soils should be zoned to permit a wide range of normal and customary farming activities, supplemental farm businesses, and other compatible activities. Non-farm land uses should be strictly limited because of the inherent conflicts between these activities. All zoning ordinances should be supported by the comprehensive plan and objective data.

The first effective agricultural zoning ordinance in Pennsylvania was adopted in York County in 1974, and other municipalities in southeast Pennsylvania have adopted their own versions since that time. Currently, Elk Township, Highland Township, Honey Brook Township, Londonderry Township, Upper Oxford Township, West Caln Township, and West Fallowfield Township in Chester County utilize effective agricultural zoning ordinances.

Upper Oxford Township is an example of a municipality that supports its agricultural zoning regulations with policies that are derived from its agricultural resources inventory and plan.
