Alabama Flood Hazard Profile

Climate-Adjusted Hazard Data · Model Version 1.0

Overview

Hazard Scoring Approach

CivilSense computes a Climate-Adjusted 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 peer-reviewed 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.
