NOTES This ~ap is for use in administering the National Flood Insurance Program; it do n?t necessarily identify all areas subject to flooding, particularly from local I ralnage sources of small size, or all planimetric features outside Special Flood Hazard Areas. Coast I 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 (lOG-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. Soun aries of the floodways were computed at cross sections and interp lated between cross sections. The floodways were based on hYdra~iC 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.
