Flood Hazard Assessment
Interactive flood risk map for all Hawaiian islands
About This Map
The FEMA National Flood Hazard Layer (NFHL) shows official flood zones from Flood Insurance Rate Maps (FIRMs) across all Hawaiian islands. Use it to check if your home, workplace, or evacuation route is in a flood-prone area.
How to use: Search your address or zoom to your area. Toggle map layers to view flood zones. Zone A and AE are high-risk areas, Zone X is moderate-to-low risk. Different colors indicate different flood risk levels.
