What are FEMA flood zones?
FEMA classifies areas into flood zones based on the probability of flooding. High-risk zones (A and V) have a 1% annual chance of flooding and require flood insurance for federally-backed mortgages. Moderate-risk zones (B/X shaded) have a 0.2% annual chance. Even in low-risk zones, about 25% of all flood claims come from areas outside designated high-risk zones. Atlantic County has 62% of ZIP codes in designated flood zones.
How are flood insurance claims calculated?
FEMA tracks every claim filed through the National Flood Insurance Program (NFIP). Claims data includes payouts for building damage and contents loss. High claim counts in an area indicate actual flood events, not just theoretical risk. Atlantic County has 20,943 recorded claims — this real-world history is often a better risk indicator than flood zone maps alone.

Understanding FEMA Flood Zones

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 dominant flood zone in Atlantic County is Zone A08.
