In 1990, Congress passed the Coastal Barrier Improvement Act (CBIA), which increased the extent of areas established by the CBRA and Protected to the system. These areas are collectively referred to added “Otherwise Areas” (OPA) as the John. H Chafee Coastal Barrier Resources System (CBRS). The CBRS boundaries that have been identified in the project area are in , Barrier Resource System “Coastal Information.” Table : Coastal Barrier Resources System Information Date CBRS Area FIRM Panel Primary Flooding Source CBRS/OPA Type Established Number(s) Big Ocean CBRS 1/1/1999 12345C0235X SECTION 4.0 AREA STUDIED – 4.1 Basin Description contains a description of the characteristics of the HUC-8 sub-basins within which each community falls.
