According to the government of Dare County, North Carolina, at least 11 homes have collapsed into the Atlantic Ocean in the small beach town of Rodanthe since 2020. As worsening storms and rising sea levels contribute to erosion along the Atlantic Coast, thousands of beach homes are at risk.

New data from FEMA’s National Flood Insurance Program sheds light on the places facing the most risk. The NFIP tracks properties that file regular flood insurance claims, an indication of systemic flooding. While nationwide there are 17.9 multiple loss properties per 10,000 housing units, in some parts of the country – like Dare County and other communities along the Atlantic and Gulf Coast – have more than 50 times that. A closer look at the data reveals the counties where coastal homes are flooding the most.

To determine where coastal homes are flooding the most, Climate Crisis 247 reviewed data on multiple loss properties from FEMA’s National Flood Insurance Program. Counties were ranked based on the number of multiple loss properties – structures with multiple NFIP claims – per 10,000 housing units. Only coastal counties were included. Supplemental data on population is from the U.S. Census Bureau.
