Floods are one of the most common hazards in the United States, and can cause loss of life as well as damage to buildings and other structures. Some floods develop slowly over a period of days, but flash floods can develop rapidly, sometimes in just a few minutes and without any visible signs of rain. Here you’ll find a “starter list” of tools and open data that can support community preparedness for floods. If there are additional free tools or open data that can be shared, please email us at disastertech@ostp.gov.
