NOTES

This map 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
Special Flood Hazard Areas.

Coastal base flood elevations only landward of 0.0 NGVD, and include
the effects of wave action; 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 may incorporate approximate boundaries of Coastal Barrier
Resource 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 have changed subsequent to the issuance of this map.

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

For adjoining map panels and base map source see separately printed
