The Agricultural Security Area Law (PA Act 43) allows the owners of farmland to enroll their property into to an Agricultural Security Area (ASA), which is administered by their municipality. Landowners whose properties are enrolled within an ASA receive special consideration regarding local ordinances affecting normal farming practices, and are also granted other benefits. PA Act 43 also mandates that the County Planning Commission review submissions for inclusion into an ASA prior to the ASA submission being approved by the municipality. The purpose of this review is to determine if the submitted parcels meet the criteria for "viable farmland" as set forth in PA Act 43. Every seven years, the Planning Commission must review all of the parcels enrolled within the ASA of a municipality, to ensure that records are up to date.
