About updates

The First Street Foundation is continuously working to refine its flood model methodology and incorporate new information into Flood Factor. A Flood Factor is based on a model designed to approximate risk and is not intended as a precise estimate. The Flood Model incorporates the latest in peer reviewed science and research to ensure we take into account the most up to date and comprehensive science in determining a Flood Factor for specific properties. As such, Flood Factors can change to reflect future data we may receive. Flood Factor is updated quarterly, while the Flood Model is updated annually.
