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 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 may incorporate approximate boundaries of Coastal Barrier Resource System .Units and for Otherwise Protected Areas established under the Coastal Barrier Improvement Act of 1990 (PL 101-591). oCorporate limits shown are current as of the date of this map. The user should contact appropriate community officials to determine if corporate Z limits have changed,;, subsequent to the issuance of this map.
