In the 50 years between the creation of the National Flood Insurance Program and 2018, nearly 37,000 properties have been categorized as “severe repetitive loss” (SRL) after sustaining multiple damaging floods. These SRL properties, which have flooded five times each, on average, are prioritized for mitigation under FEMA’s Flood Mitigation Assistance grants and other programs. However, according to FEMA data, less than one third of SRL properties have been mitigated—fewer than have dropped out of the NFIP without having been mitigated. If current programs and policies cannot keep up with the existing mitigation needs of the most flood-prone properties, what does that mean for the future? And what does that mean for the communities that are being left behind? This presentation will examine the locations, characteristics, and mitigation trends of SRL properties across the United States using the Natural Resources Defense Council’s interactive SRL data visualization tool, “Losing Ground.” The presentation will also examine the demographics of communities that have large numbers of non-mitigated SRL properties and discuss the equity implications for hazard mitigation policy.
