Lee County Flood Zones
County seat: Fort Myers. 792,692 residents. Coastal county — Southwest Florida (Gulf).
Flood risk in Lee County
Located in Florida's southwest region, Lee County faces a dual threat of extreme storm surge and high rain flood risk due to its extensive coastal exposure and low-lying terrain. This vulnerability is evident in densely populated areas such as Fort Myers and Cape Coral, where recent federal disaster declarations highlight the severity of the hazard landscape. The county has experienced significant impacts from multiple major events in recent years, including Hurricane Ian in 2022 and Hurricane Milton in 2024, both of which were followed by Tropical Storms Helene and Debby within the same calendar year as Milton. These successive storms demonstrate the persistent nature of the threat to the region's 792,692 residents, with storm surge posing an extreme danger to waterfront properties while heavy rainfall creates widespread inland flooding. Sanibel and Bonita Springs also remain critical areas of concern given their geographic position and exposure to these meteorological events. Homeowners and prospective buyers in this area must verify their specific flood zone designation and evacuation routes before purchasing property or renewing insurance policies.
