Learn about updates to Flood Factor and the First Street Foundation Flood Model.
The First Street Foundation is continuously working to refine its flood model methodology and incorporate new information into Flood Factor. The Flood Factor score 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 score for specific properties. As such, scores can change to reflect future data we may receive and scores will then be revised in future scheduled updates as appropriate. Flood Factor is updated quarterly, while the Flood Model is updated annually. Sign up for our newsletter to learn about updates as they become available by clicking or tapping here.
