SPECIAL flOOD HAZARD AREAS INUNDATED
BY 10o-YEAR FLOOD
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
flow on sloping terrain); average depths
determined. For areas of alluvial fan flooding,
velocities also determined.

ZONE A99 To be protected from 10o-year flood by
Federal flood protection system under
construction; no base elevations determined.

ZONE V Coastal flood with velocity hazard (wave
action); no base flood elevations determined.

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

FlOODWAY AREAS IN ZONE AE

OTHER flOOD AREAS
ZONE X Areas of SOO-year flood; areas of 10o-year
flood with average depths of less than
1 foot or with drainage areas less than
1 square mile; and areas protected by
levees from 10o-year flood.

o

OTHER AREAS
ZONE X Areas determined to be outside SOo-year
floodplain.

ZONE D

Areas in which flood hazards are
undetermined.

NOTES

This 'illap is for use in administering the National Flood Insurance Program;
it do~s not necessarily identify all areas subject to flooding, particularly from
local,rainage sources of small size, or all planimetric features outside
Speci I Flood Hazard Areas.

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

Areas! of Special Flood Hazard (lOG-year flood) include Zones A, AE, AH, AD,
A99, V, and VE.

Certaih areas not in Special Flood Hazard Areas may be protected by
flood' control structures.

Boun~aries of the floodways were computed at cross sections and
interpplated between cross sections. The floodways were based on
hydra~lic considerations with regard to requirements of the Federal
Emer~ency Management Agency.

Floodray widths in some areas may be too narrow to show to scale.
Floodyvay widths are provided in the Flood Insurance Study Report.

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

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

For ~ommunity map revision history prior to countywide mapping, see
Section 6.0 of the Flood Insurance Study Report.
