New data discloses the flood risk of every home in the U.S.
Nonprofit research and technology group First Street Foundation has released flood risk data for more than 142 million homes and properties across the country.
The data assigns every property in the contiguous United States a "Flood Factor™," or score from 1 to 10, based on its cumulative risk of flooding over a 30 mortgage. People can look up a property's Flood Factor and learn more about its past, present, and future flood risk at FloodFactor.com, the Foundation's new online visualization tool.
