Learn about the similarities and differences between FEMA and Flood Factor assessments across the country.
FEMA flood maps identify over 1.1 million miles of flood hazard areas, and while the maps can provide detailed information for homeowners on their flood risks, they are not available everywhere. Flood Factor’s national flood model shows that flood risk is more widespread in the United States, with over 24 million properties at risk over the next 30 years. Flood Factor also includes flood risk from extended periods of high-intensity rainfall, leading to urban stormwater flooding and storm surge. Additionally, future conditions are considered, such as sea level rise.
