Peach Bottom Township utilizes sliding scale zoning in its agricultural zoning ordinance.  Sliding scale zoning is used to retain large farm parcels while allowing for limited residential development.  As the density table in this ordinance illustrates, fewer acres are required per residential unit or subdivision for smaller parcels in comparison to larger parcels.  Peach Bottom Township has also established maximum lot sizes for new residential subdivision of one acre, unless the land cannot be feasibly farmed.
