DVRPC maintains an inventory of protected public and private open space in the Delaware Valley. The inventory tracks all publicly-owned open space, preserved farmland, and non profit protected open space. State, county and municipal programs preserve farms by purchasing development rights with public funds. Non-profits (land trusts and conservancies) protect privately owned open space lands by purchasing easements or by acquiring land outright with a combination of public and private funds. This file is a compilation from the following sources: Burlington County Department of Resource Conservation; Camden County Department of Public Works; Gloucester County Public Works, Planning Division ; Mercer County Planning Department; NJDEP, Bureau of GIS; Bucks County Planning Commission; Chester County Planning Commission; Delaware County Planning Department; Montgomery County Planning Commission; City of Philadelphia; WeConservePA; DVRPC In the cases where land had multiple owners, the following hierarchy was applied: 1. Preserved Farmland 2. Federal 3. State 4. County 5. Municipal 6. Nonprofit
