I NOTES

lIhis map is for use in aaministering the National Flood Insurance
~rogram; it does not necessarily identify all areas subject to flooding,
particularly from local drainage sources of sm'all size, or all planimetric
features outside Special Flood Hazard Areas.
I
1reas of special flood hazard (IOO-year flood) include Zones A, AI-30,
4E, AH, AO, A99, V, VI-30 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
it;1terpolated between cross sections. The floodways Were based on
hydraulic considerations with regard to requirements of the Federal
Smergency Management Agency.

Fjloodway widths in some areas may be too narrow to show to scale.
FioOdway widths are provided in the Flood Insurance Study Report.

Qoastal base flood elevations apply only landward of the shoreline.
