The Federal Emergency Management Agency, which assesses properties' flood risk for the government via the National Flood Insurance Program, shows that 8.7 million properties are at a high risk of flooding.

Recent studies found that the federal government needs to spend up to $12 billion to improve its flood maps. In the meantime, First Street is developing a free online database called Flood Factor aimed at helping real estate agents and prospective buyers get a more realistic idea of a property's flood risk.
First Street is a non-profit research and tech firm that developed its flood model with researchers and hydrologists from the Massachusetts Institute of Technology, Columbia University and more.
