NOTES

This ~ap 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
Speci I Flood Hazard Areas.

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

Areas of Special Flood Hazard (100-year flood) include Zones A. AE, AH, AO,
A99, . and VE.

Certai areas not in Special Flood Hazard Areas may be protected by
flood control structures.

Boun aries of the floodways were computed at cross sections and
interp lated between cross sections. The floodways were based on
hydra lie considerations with regard to requirements of the Federal
Emer ency Management Agency.

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

This ap may incorporate approximate boundaries of Coastal Barrier
Resou ce System Units and lor Otherwise Protected Areas established
under the Coastal Barrier Improvement Act of .1990 (PL 101-591).

Corpo ate limits shown are current as of the date of this map. The user
shoul contact appropriate community officials to determine if corporate
limits have changed subsequent to the issuance of this map.

For c~mmunity map revision history prior to countywide mapping, see
Sectio 6.0 of the Flood Insurance Study Report.
