NOTES

This map is for use in administering the National Flood Insurance Program;
It does not necessarily identify all areas subject to flooding, from
local sources of small size. or all planimetric outside
Special Hazard Areas.

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

Areas of Special Flood Hazard (100-year flood) include Zones A, AE, AH, AO,
A99, V, 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
interpolated between cross sections. The floodways were based on
hydraulic considerations with regard to requirements of the Federal
Emergency Management Agency.

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

This map boundaries of Coastal Barrier
Resource and Otherwise Protected Areas established
under the Barrier Improvement Act of 1990 (PL 101-591).

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