ZONE A99 To be protected from 10o-year flood by Federal flood protection system under construction; no base elevations determined. ZONE V Coastal flood with velocity hazard (wave action); no base flood elevations determined, ZONE VE Coastal flood with velocity hazard (wave action); base flood elevations determined. FLOODWAY AREAS IN ZONE AE OTHER FLOOD AREAS ZONE X Areas of SOo-year flood; areas of 10o-year flood with average depths of less than 1 foot or with drainage areas less than 1 square mile; and areas protected by levees from 10o-year flood.

Areas (f 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 ontrol structures. Bound~ries 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 Emerg~ncy Management Agency. FIOOd~ay widths in some areas may be too narrow to show to scale, FIOOd1ay widths are provided in the Flood Insurance Study Report.
