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. Refer to Floodway Data Table where floodway width is shown at 1/20 inch. Coastal base flood elevations apply only landward of 0.0 NGVD, and include the effects of wave action; these elevations may also diff~r significantly from those developed by the National Weather Service for hurricane evacuation planning.
