FLOOD-ZONE MAP FEMA NFHL · LIVE Where the high-risk flood zones are in Charleston
This is Charleston drawn live from FEMA’s National Flood Hazard Layer. Every shaded area is a
Special Flood Hazard Area — a high-risk zone where a federally backed mortgage requires flood
insurance, and the first thing a carrier checks after a water loss. Your homeowners policy does not cover
flood; that takes a separate NFIP or private flood policy. Pan and zoom to your street to see your zone.
FEMA FLOOD ZONES · CHARLESTON Loading live data…
Zone VE
Coastal high-hazard. Storm surge with waves on top — the most dangerous zone, along the open water.
Zone AE
The 1%-annual-chance floodplain (the “100-year” zone). FEMA sets a Base Flood Elevation here.
A / AH / AO
Other high-risk areas — shallow sheet flooding, ponding, or floodplain not yet studied in detail.
Unshaded (X)
Moderate-to-low risk — not no risk. Over a quarter of federal flood claims come from outside the high-risk zones.

LIVE CONDITIONS NWS · NOAA · LIVE Radar, forecast & tides for Charleston
Live from the National Weather Service and NOAA — the local Doppler loop, the official 7-day forecast, and the
next high and low tides. Tides and surge timing decide how bad a coastal flood gets; a storm arriving at high
tide floods far more than the same storm at low tide.

How the risk changes across Charleston
Flood exposure is hyper-local. These are the broad patterns by area, keyed to FEMA zones and the way water
moves here — surge off the bay, the Charleston County river system, and low interior drainage. General
reference only; confirm your exact address on the map above.
South of Broad / The Battery VE / AE
STORM SURGE
The peninsula's low southern tip on the harbor — among the most surge- and tidal-flood-exposed ground in the city.
French Quarter / Waterfront AE
COASTAL FLOOD
Historic harbor edge; AE flooding from surge and king-tide backup into the streets.
Harleston Village / Colonial Lake AE
COASTAL FLOOD
Low western peninsula around the tidal lake; recurrent AE flooding on heavy rain and high tides.
Wagener Terrace / North Central AE pockets
SURGE + FLOOD
Ashley-River side of the upper peninsula; higher lots with low AE pockets near the marsh.
West Ashley AE
SURGE + FLOOD
Across the Ashley — creek and marsh AE flooding along the water, higher ground inland.
James Island AE
COASTAL FLOOD
Threaded with tidal creeks and marsh; AE flooding from surge and creek backup.
Daniel Island AE
COASTAL FLOOD
Island in the Wando/Cooper; waterfront AE with higher interior ground.
The Neck / upper peninsula AE
SURGE + FLOOD
Low industrial and residential ground between the rivers; AE flooding where drainage backs up.
