First Street Foundation is a nonprofit 501(c)(3) research and technology group based in Brooklyn, NY, whose mission is to define and communicate America's flood risk based on the highest standards of scientific investigation and analysis. First Street uses transparent, peer-reviewed methodology to model past, present and future flood risk of individual homes and properties across the United States. Through Flood Factor, an online visualization tool, the Foundation makes its data accessible to the public for free. First Street also shares its data directly with leading economists, engineers, risk experts, and other researchers so those experts can analyze the national implications of flood risk. The First Street team is made up of scientists, technologists and communicators.
