Flood Risk in Pennsylvania

Pennsylvania has areas at risk of flooding from various sources including rivers, coastal storms, and heavy rainfall. FEMA has mapped flood zones across the state to identify areas at risk.

Understanding Pennsylvania Flood Zones

FEMA designates flood zones across Pennsylvania using the following classifications:

AE High Risk — 1% annual chance of flooding (100-year floodplain). Insurance required for federal mortgages.

VE Very High Risk — Coastal flooding with wave action. Strictest building codes.

X (Shaded) Moderate Risk — 500-year floodplain. Insurance recommended.

X Low Risk — Outside major floodplains. Insurance optional but advisable — 20%+ of NFIP claims come from low-risk zones.

Flood Insurance in Pennsylvania

Properties in Pennsylvania FEMA-designated Special Flood Hazard Areas (zones A and V) with federally backed mortgages are required to carry flood insurance through the National Flood Insurance Program (NFIP).

Even outside high-risk zones, flood insurance is recommended. NFIP claims data shows that over 20% of claims nationwide come from low and moderate-risk areas. Pennsylvania residents can purchase flood insurance through the NFIP or private insurers.
