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 only landward of 0.0 NGVD, and include
the effects of wave action; elevations may also differ
from those developed by the National Weather Service for
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
considerations with regard to requirements of the Federal
Management Agency.
