Historical Claim Records per Capita
Arapahoe County has 0.3 historical NFIP claim records per 1,000 residents. This rate only normalizes recorded claim activity for population size. It does not measure current flood probability, property risk, distinct events, or uninsured losses.
Understanding Current FEMA Map Zones
FEMA classifies areas into flood zones based on the annual probability of flooding:
Zone A / AE — High risk. 1% annual flood chance (100-year floodplain). Flood insurance required for federally-backed mortgages
Zone V / VE — High risk coastal. 1% annual flood chance plus storm wave action
Zone B / X (shaded) — Moderate risk. 0.2% annual flood chance (500-year floodplain)
Zone C / X (unshaded) — Minimal risk. Outside the 500-year floodplain
The most frequent rated-zone value in the county's historical NFIP claim records is AE. It is not the county's dominant current FEMA map zone and cannot determine a property's designation. Check the exact address in FEMA's current map.
