How are the flood hazard maps used?
Flood hazard maps are used to determine the flood risk to your home or business. The low- and moderate-risk zones are represented on the maps by the letters “B”, “C”, “X” or an “X” that is shaded. The inland high-risk zones are labeled with designations such as “A”, “AE”, “AO” or “AH”. Coastal high-risk zones that have additional risk from storm surge are labeled “V” or “VE”. These high-risk zones represent areas that have a 1-percent chance of flooding each year.
