NOTES

This map is for use in aoministering 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 Floo'd Hazard Areas,

Areas of special flood hazard (lOO-year flOOd) include Zones A, AI-30,
AE, 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
interpolated between cross sections, ,:The floodways were based on
hydraulic considerations with regard 10 requirements of the Federal
Emergency Management Agency.

Floodway widths in some areas may be too narrdw to show to scale.
Floodway widths are provided in the Flood I nsurance Study Report.

Coastal base flood elevations apply only landward of the shoreline,
