SPECIAL flOOD HAZARD AREAS INUNDATED
BY 100- 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 deter-
mined. For areas of alluvial fan flooding;
velocities also determined,

ZONE A99 To be protected from 100-year flood by
Federal flood protection system under con-
struction; no base flood elevations deter-
mined.

ZONE V Coastal flood with velodtyhazard (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 500-year flood; areas of 100-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 100-year
flood. .

OTHER AREAS
Z ON E X Areas determmed to be outside 500-year flood-
plain.

ZONE 0

Areas in which flood hazards are undeter-
mined.

~ NOTES

Th map is for use in administertng the National Rood Insurance Program;
it. not necessarily identify all areas subject to flooding, particularly from
10;J.1 drainage sources of small size, or all planimetric features outside
Sp~cial Flood Hazard Areas. The community map repository should be
consulted for more detailed data on BFEs, and for any information on
f10pdway delineations, prior to use of this map for property purchase or
construction purposes.

Areas ot Special Flood Hazard (100-year flood) include Zones A, AE, A1-
A39, AH, AO, A99, V, VE and V1-V30.

Ce~ain areas not in Special Flood Hazard Areas may be protected by flood
control structures.

Bo~ndaries of the f100dways were computed at cross sections and
interpolated between cross sections. The f100dways were based on
hydraulic considerations with regard to requirements of the Federal
En:ergency Management Agency.

Floixmay widths in some ,areas may be too narrow to shoW to scale. Hefer
to ,Ioodway Data Table where f1oodwaywi~h is shown at 1/20 inch.

Co~stal base flood elevations apply only landward of 0.0 NGVD, and
include the effects of wave action; these elevations may also diff~r
siqnificantly from those developed by the National Weather Service for
hu,ricane evacuation planning.

cdrporate limits shown are current as of the date of this map. The user

Iiniits have changed subsequent to the issuance of this map.
