As part of its nationwide effort to update the Nation’s flood hazard maps, FEMA is paying particular attention to coastal areas. With approximately 39% of the Nation’s population living in a coastal county (i.e., a county that is contiguous with the coast or that has Special Flood Hazard Areas caused by coastal flooding identified), it is vital that residents and businesses in these communities have accurate flood hazard information, know their flood risk, and take steps to protect their lives and property.
