Methodology

Flood risk rankings use FEMA National Flood Insurance Program (NFIP) claim data. Total claims reflect historical flood events that resulted in insured property damage. High claim counts indicate areas with recurring flood exposure, which can compromise water infrastructure, introduce contaminant runoff, and damage home systems.

Data sources: EPA Safe Drinking Water Information System (SDWIS), FEMA National Flood Insurance Program, EPA radon zone maps, EIA electricity rates, and Consumer Confidence Reports. Last updated: 2026-06-04.

Frequently Asked Questions

Why does flood history matter for home safety?

Flooding can contaminate drinking water supplies, damage water infrastructure, introduce sewage and chemical runoff, and compromise home foundations and electrical systems. Repeated flooding indicates persistent risk that affects long-term home safety.

Where does the flood data come from?

Flood claim data comes from the FEMA National Flood Insurance Program (NFIP), which tracks all insured flood losses by ZIP code. This includes claims from hurricanes, river flooding, storm surge, and heavy rainfall events.
