Coastal flooding disproportionately affects certain US counties
Recent data from FEMA’s National Flood Insurance Program (NFIP) shines a spotlight on the regions most susceptible to repeated flooding. The NFIP meticulously tracks properties with frequent flood insurance claims, offering a clear indicator of ongoing flood risk. While the national average stands at 17.9 "multiple loss" properties per 10,000 housing units, certain coastal counties, especially those along the Atlantic and Gulf Coasts, experience rates exceeding 50 times this average.
