Coastal Barrier Resources System Mapper

In response to Hurricane Sandy, the Service has made an interactive Coastal Barrier Resources System (CBRS) Mapper available to the public. The mapper can be used to help property owners, local, State, and Federal stakeholders, and the public determine whether or not properties or project sites may be affected by CBRA. The Coastal Barrier Resources System (CBRS) boundaries depicted in the mapper are representations of the controlling CBRS boundaries, which are shown on the official CBRS maps. The boundaries depicted in the mapper are not to be considered authoritative for in/out determinations close to a CBRS boundary (i.e. the area depicted within the “CBRS Buffer Zone”).

The CBRS Mapper integrates digital map data with other resource information to produce timely and relevant management and decision support tools. We recommend looking at the following prior to launching a map:
