Derived from FEMA National Flood Hazard Layer (NFHL) designations. Scores range from 1 (highest risk — coastal high-hazard zone subject to wave action, FEMA V/VE; typically associated with elevated insurance costs) through moderate undetermined-risk and 500-year floodplain zones, to 255 (minimal flood hazard, FEMA Zone C). A score of 0 means no FEMA data is available.
