How this ranking works
Flood ranking uses normalized FEMA/NFHL-derived tile scoring with guardrails for sparse or low-land-fraction cells.
Rankings are built from HomeRiskIQ hazard tiles and current state/city scoring. They are designed for comparative research and media context, not official warning decisions.
