Focused on US flood-prone regions (TX, FL, LA, NC, NJ + Mississippi/Missouri river basins)

Flood risk data.
For any US location.

Every score is computed from decades of public records using physics-based probability modeling, scored at neighborhood resolution. Finer than the county-level averages most public data provides, with the same data layer used by insurance and risk management professionals.

Methodology

Public data. Real science. No black boxes.

Every score is computed from decades of public weather records using physics-based probability modeling. It's the same approach used by insurance and risk management professionals.

Decades of public weather data: Hurricane tracks, storm intensities, fire perimeters, hail reports, all drawn from public scientific archives. We don't use proprietary data. You can audit every input.
Physics-based probability modeling: Scores reflect how the actual peril behaves: wind fields, fire spread, ground shaking, and storm tracks. The model keeps the physics visible instead of flattening every place into a broad average.
Used by professionals: The same PerilScore data layer is used by insurance and risk management professionals. We publish it here so anyone can find authoritative risk numbers for their location.

Frequently asked questions

Where does the flood risk score come from?

Every score is computed from decades of public weather data (gauge records, precipitation history, terrain, and watershed modeling) using physics-based probability modeling for both river and rainfall flooding.

How is this different from a FEMA flood zone?

FEMA flood zones are regulatory boundaries used to set flood insurance requirements. Our score is a continuous probability designed for actual risk modeling. Many properties outside FEMA zones still carry meaningful flood probability.

Does this cover pluvial (rainfall) flooding?

Yes. Pluvial flooding from intense rainfall is one of the largest uninsured losses in the U.S. Our score accounts for both pluvial and fluvial sources.
