App · Weather & Space · 10 actions

Look up official US disaster information from FEMA's open data. Find the federal disasters declared for any state or county since 1953 and what each one unlocked, then follow the money: the rebuilding projects FEMA funded, the grants that went to households, and the work paid for to reduce the damage next time. Check whether a community takes part in the National Flood Insurance Program, how many of its homes carry flood insurance, and what has been paid out there before. Search the archive of public emergency alerts, and see which federal agencies were sent in. Dates come back as plain dates, money in dollars, and FEMA's internal codes as words. No account or API key is required.

Actions

ActionWhat it does
Check flood insurance statusFind out whether a community takes part in the National Flood Insurance Program, and so whether flood insurance can be bought there at all.
Find disaster declarationsSearch every federally declared disaster since 1953: by state, county, kind of disaster, when it was declared, and which kinds of help it unlocked.
Find emergency alertsSearch the archive of public warnings sent through IPAWS, the system behind the alerts on American phones, radio and television: tornado warnings, evacuation orders, child abduction emergencies and the rest.
Find federal mission assignmentsFind which other federal agencies FEMA sent in for a disaster, what each was asked to do, and what it was paid.
Find hazard mitigation projectsFind the work FEMA funded to reduce the damage from the next disaster: buying out flood-prone homes, raising buildings, safe rooms, flood walls, backup generators.
Find public assistance projectsFind the rebuilding work FEMA funded after a disaster (debris removal, roads and bridges, schools, water systems) and what each project cost.
Get disaster detailsEverything FEMA publishes about one disaster: what it was and when, which programs it turned on, every county it covered, and how much has been approved or obligated under each program.
Get disaster housing assistance for an areaAdd up the housing help FEMA gave households in one area: how many applied, how many were approved, and how much was paid for repairs, rent and other needs.
Get flood insurance claim historyWhat the National Flood Insurance Program has paid out in one area since 1970: how many claims, how much in total, the average and the largest, a year-by-year breakdown, and the floods and causes behind them.
Get flood insurance coverage ratesHow many homes in a county actually carry flood insurance, as a share of all homes and as a share of the homes inside the mapped flood zone.

Check flood insurance status
