About FloodRiskData

Is your home in a flood zone?

What we do

FloodRiskData pulls FEMA flood-zone maps, NFIP claim history, and disaster declarations into a single address-level flood picture.

We focus on U.S. flood risk, NFIP claims, and disaster declarations. Every page on floodriskdata.org is built from OpenFEMA (the Federal Emergency Management Agency open-data portal), cited and linkable so readers can trace any number back to its source.

Who this is for

FloodRiskData is built for home buyers, homeowners, real-estate agents, insurance shoppers, and risk managers.

Why this exists

Public data on U.S. flood risk, NFIP claims, and disaster declarations is technically free, but practically locked behind file formats, acronyms, and paywalled dashboards. FloodRiskDataexists to close that gap: take the raw federal and public-sector data, and turn it into pages a normal person can read in thirty seconds.

How we work

  • Primary source only. We pull from OpenFEMA (the Federal Emergency Management Agency open-data portal) and cite the exact dataset and version on every page.
  • No invented numbers. If a figure is not in the underlying public data, it does not appear on floodriskdata.org. We never generate synthetic statistics to fill gaps.
  • Refreshed on a schedule. Data is refetched on a published cadence — you can see the "Last updated" date on every dataset page.
  • Corrections welcome. Readers flag issues all the time. When the source fixes a record, FloodRiskData follows.

Independence

FloodRiskData is an independent publication. We are not funded, owned, or directed by any of the agencies, companies, or organizations that appear in our data. Hosting is paid for by advertising — see our Privacy Policy for details — and we do not take paid placements, sponsored rankings, or "remove-my-entry" fees.

History

FloodRiskData launched in 2026 as part of a small portfolio of independent public-data sites. It has been maintained and updated continuously since.
