Georgia Flood Hazard Profile

Climate-Adjusted Hazard Data · Model Version 1.0

Overview

Georgia experiences flood hazard from coastal storm surge along the Savannah and Brunswick coastline, riverine flooding along the Chattahoochee, Flint, and Ocmulgee rivers, and urban flash flooding in the Atlanta metro area. The 2009 Metro Atlanta flood was a benchmark event for urban flood exposure.

Notable Historical Events

12009 Metro Atlanta Flood — $500M+ damage, 10 fatalities (FEMA DR-1858)
22016 Hurricane Matthew — coastal flooding in Chatham County
32024 Hurricane Helene — catastrophic inland flooding in north GA

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.
