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

on sloping terrain); average depths deter-
mined. For areas of alluvial fan flooding;
velocities also determined.

ZON E AO

Federal flood protection system under con-
struction; no base flood elevations deter-
mined.

action); no base flood elevations determined.

Areas of SOO-year flood; areas of l00-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 l00-year
flood.

NOTES

This map is for use in administering the National Flood Insurance Program;
It does not necessarily identify all areas sU,bject to flooding, particularly from
local drainage sources of small size, or all planimetric features outside
Special Flood Hazard Areas. The community map repository should be
consulted for more. detailed data on BFEs, and for any information on
floodway. delineatioJ1s, prior to use of this map for property purchase or
construction purposes.

Areas of Special Flood Hazard (1 OO-year flood) include Zones A, AE, A 1-
A30, AH, AO, A99, V, VE and V1-V30.

Certain ar~as not in Spedal Flood Hazard Areas may be protected by flood
control structures.

Boundarh~s of the floodways were computed at cross sections and
interpolated between cross sections. The f100dways were based on
hydraulic considerations with regard to requirements of the Federal
Emergency Management Agency.

Flooctvvaywidths in some areas may be too narrow to show to scale. Refer
to Floodway Data Table wherp. floodway width is shown at 1/20 inch.

~oastal base flood elevations apply only landward of 0.0 NGVD, and
I~clude the effects of wave action; these elevations may also diff~r
significantly from those developed by the National Weather Service for
hurricane evacuation planning.

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