Florida Flood Hazard Profile
Hazard Data · Model Version 2.5
Overview
Florida has more NFIP policies in force than any other US state, reflecting its low elevation, high water table, and tropical rainfall exposure. FEMA flood zone mapping shows extensive Special Flood Hazard Areas (SFHAs) along both coastlines and in interior drainage basins. Storm surge flooding from tropical cyclones compounds rainfall-driven inland flood risk.

Hazard Scoring Approach
Calchis computes a Calchis Hazard Score (0–10) for flood hazard at any US address. The score is composed of weighted sub-components derived from federal data sources and published research. All score components are transparent and returned in API responses.
These are hazard scores — physical intensity likelihood only. They do not include property exposure or vulnerability data. We never call a hazard score a risk score. See the full methodology for scoring details.
