The Advisory Flood Zones are intended to serve as the best available data for understanding coastal and riverine flood hazard risk and the elevations that communities should build to in order to protect themselves from future flood events. The Advisory Coastal A Zone is intended to serve as the best available data for understanding coastal flood hazard risk and the elevations that communities should build to in order to protect themselves from future coastal flood events. Areas within the Coastal A Zone are subject to waves equal to or greater than 1.5 ft but less than 3 ft. Post-disaster building inspections and scientific studies have shown that waves equal to and greater than 1.5 ft are sufficient to induce structural damage to many National Flood Insurance Program compliant structures on shallow or solid wall foundations. The FEMA Coastal Construction Manual and American Society of Civil Engineers recommend Zone VE construction practices inside of the Coastal A Zone. The 2018 International Residential Building Code requires higher building standards in Coastal A Zones. As part of the long term recovery effort,the ABFEs and the 0.2% Coastal A Zone are tools for Federal, State, and local officials, building officials, builders and architects, insurance professionals, and property owners to make informed decisions during rebuilding and to mitigate losses from future flood events, safeguard lives, and protect the private and public investment in rebuilding. |

| description:
|
The Federal Emergency Management Agency (FEMA) has developed the Advisory Flood Zones. They provide full geospatial representation of the coastal and riverine Advisory Base Flood Elevations (0.2% annual chance flood hazard), including coastal storm surge and wave components. |

This product is not be used as information to support regulatory floodplain designation or insurance ratings. Use of data is to provide the FEMA with guidance to disseminate to communities rebuilding after Hurricane Maria. The advisory elevations do not include freeboard and/or any additional safety factor to account for potential future increases of the coastal flood hazard due to sea level rise. Advisory mapping information was not adjusted to provide a seamless tie to any existing hazard Flood Insurance Study (FIS) mapping in adjacent areas. |
