Agricultural Security Areas

About the ASA Program

As a tool to protect farms and farmland from non-agricultural uses, Agricultural Security Areas (ASAs) are intended to promote viable farming operations over the long term by strengthening the 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. To create an ASA, landowners may petition 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.  Landowners that enroll in an ASA commit to remaining in it for seven years. After fulfilling their seven-year commitment, landowners may withdraw at any time. Each municipality may add new enrollees to an established ASA at any time.

  • 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.

The larger the acreage in an ASA, the more beneficial it is to your neighbors that may wish to preserve their farmland forever.
