| Zoning - agricultural protection zoning (APZ) |
Zoning is a form of local land use regulation. Agricultural protection zoning ordinances protect the agricultural land base by limiting non-farm uses, prohibiting high-density development, requiring houses to be built on small lots and restricting subdivision of land into parcels that are too small to farm. APZ takes many forms including: exclusive agricultural zoning, large minimum lot size zoning, area-based allowance zoning, fixed area-based allowance zoning; and sliding scale area-based allowance. |
