Otherwise Protected Areas (OPAs) are a category of coastal barriers within the Coastal barrier Resources System (CBRS). OPAs are undeveloped coastal areas established under Federal, State, or local law, or held by a qualified organization, primarily for wildlife refuge, sanctuary, recreational, for natural resource conservation purposes. Flood insurance is restricted in OPAs, though OPAs may receive other forms of Federal assistance. OPAs are identified on FEMA FIRMs.
