ZONE A No base flood elevations determined.

ZONE AE

Base flood elevations determined.

ZONE AH Flood depths of 1 to 3 feet (usually areas
of ponding); base flood elevations
determined.

ZONE AO Flood depths of 1 to 3 feet (usually sheet

action); no base flood elevations determined.

ZONE VE Coastal flood with velocity hazard (wave
action); base flood elevations determined.

NOTES

This 'llap is for use in administering the National Flood Insurance Program;
it does not necessarily identify all areas subject to flooding, particularly from
local drainage sources of small size, or all planimetric features outside
speci11 Flood Hazard Areas.

Coast~1 base flood elevations apply only landward of 0.0 NGVD, and include
the effects of wave action; these elevations may also differ significantly
from I those developed by the National Weather Service for hurricane
evacu~tion planning.

Areaslof Special Flood Hazard (10o-year flood) include Zones A, AE, AH. AO,
A99, Y; and VE.

Certain areas not in Special Flood Hazard Areas may be protected by
flood \control structures.

Boundaries of the floodways were computed at cross sections and
interpblated between cross sections. The floodways were based on
hydraJlic considerations with regard to requirements of the Federal
Emergency Management Agency.
f
FloodJvay widths in some areas may be too narrow to show to scale.
FloodWay widths are provided in the Flood Insurance Study Report.

This ~ap may incorporate approximate boundaries of Coastal Barrier
Resource System Units and lor Otherwise Protected Areas established
under i the Coastal Barrier Improvement Act of 1990 (PL 101-591).

Corpotate limits shown are current as of the date of this map. The user
shoulq contact appropriate community officials to determine if corporate
limits I have changed subsequent to the issuance of this map.
