Coastal basa flood elevations apply only landward of 0,0 NGVO. and include the effects of wave action; these elevations may also ditter 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, AD. 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 lit cross sections and interpolated between cross s9ctions. The Iloodways were based on hydraulic considerations with regard to requirements of the Federal Emergency Manag&ment Agency. Floodway widths in some areas may be too nstrow to show to scale. Floodway widths are provided In the Flood Insurance Study Report, This mep may incorporate epproJlimate boundaries of Coastal Barrier Resource System Un~ and lor Otherwise Protected Areas established under the Coastal BarTier Improvement Act of 1990 lPl 1m-691j.
