The data included in the layer enables GIS to map, as polygons, the extents of all current Brownfield Development Areas (BDAs) in New Jersey. A brownfield is any former or current commercial or industrial site that is currently vacant or underutilized and on which there has been, or there is suspected to have been, a discharge of contamination. Under the BDA approach, NJDEP works with selected communities affected by multiple brownfields to design and implement remediation and reuse plans for these properties simultaneously. The BDA approach enables remediation and reuse to occur in a coordinated fashion. In the process, we invite the various stakeholders, including owners of contaminated properties, potentially responsible parties, developers, community groups, technical experts for the local government and residents, and residents themselves, to participate in this cleanup and revitalization approach.
