Agricultural Security Areas

About the ASA Program

Agricultural Security Areas are a tool to protect farms and farmland from non-agricultural uses. ASAs are intended to promote viable farming operations over the long term by strengthening the farming community’s right to farm. Pennsylvania took the first step toward protecting farmland when it adopted an Agricultural Security Area law (PA Act 43) in 1981.

Local municipalities create ASAs in cooperation with individual landowners, who agree to collectively place at least 250 acres in an agricultural security area. Landowners initiate the process of creating an ASA by petitioning their municipality, which approves the application in accordance with Act 43. The municipality is responsible for renewing the area every seven years. Participation is voluntary. New farm parcels may be added to or removed from an established ASA at any time.


Landowners who wish to enroll their property in an agricultural security area may fill out an enrollment form. Submit three copies including the required map by certified mail and requesting a return receipt to the township in which the proposed ASA is located.

  • Special consideration during review of farmland condemnation by state and local government agencies.
  • May qualify for a lower interest rate when applying for federal loans.

Eligible Property

  • Non-contiguous farm parcels must be at least 10 acres in size. The farm tracts needed to create a new 250-acre or larger Agricultural Security Area need not be under the same ownership or even located in the same municipality. The Agricultural Area Security Law (Act 43 of 1981) allows for the creation of joint municipality agricultural security areas.
  • The property in an ASA should be viable agricultural land, including cropland, pasture, and woodland.
  • At least 50 percent of the land should be in Soil Capability Classes I-IV, as defined by the county soil survey.
  • The property must be zoned to permit agricultural uses.
