This map is for use in
Program; it does not necessarily
particularly from local
features outside Special

Areas of special flood hazard (lOO-year flood) include Zones A. AI.30,
AE, AH, AD, 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 betwe~n 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 oe too narrow 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.

Elevations reference marks are described in the Flood Insurance Study
Report,
