NOTES

This map is for use in administering the National Flood Insurance Program;
it doe$ not necessarily identify all areas subject to flooding, particularly from
local ~rainage sources of small size, or all planimetric features outside
Special Flood Hazard Areas.
I
Coastdl base flood elevations apply only landward of 0.0 NGVD, and include
the effects of wave action; these elevations may also differ significantly
from I those developed by the National Weather Service for hurricane
evaculfion planning.

Areas lof 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 bontrol structures.

Bound~ries of the floodways were computed at cross sections and
interpqlated between cross sections. The floodways were based on
hydra~lic considerations with regard to requirements of the Federal
Emergency Management Agency.
i
FloodJtay widths in some areas may be too narrow to show to scale.
Flood~ay widths are provided in the Flood Insurance Study Report.
I
This map may incorporate approximate boundaries of Coastal Barrier
Resour,ce System Units and lor Otherwise Protected Areas established
under! the Coastal Barrier Improvement Act of 1990 (PL 101-591).

Corpo~te limits shown are current as of the date of this map. The user
shouldl contact appropriate community officials to determine if corporate
