Frequently asked questions
What is the flood risk in Maricopa County?
Historical signal from FEMA NFIP: 311 total claims, very-high bucket. Bucket thresholds: low (<10), moderate (10 to 49), high (50 to 199), very-high (200+).
Is historical data a forecast?
No. Historical claims are a backward-looking signal. Climate change, upstream development, and local flood mitigation investment can all shift future risk.

Mortgage lenders typically require flood insurance for properties in a FEMA designated Special Flood Hazard Area. Even outside those areas, NFIP or private flood insurance is often advisable if any historical claims exist in the county.
