This map is for use in aClministering the National Flood Insurance
rrogram; it does not nece,ssarily identify all areas subject to flooding,
f..... artlcularlyfrom local drainage sources of sm'all size, or all planimetric
. atures outside Special Flood. Hazard Areas.

I reas of special flood hazard (lOO-year flood) include Zones A"Al-30,
tE, AH, AG, A99, V, Vl-30 AND VE,

Certain areas not in Special Flood Hazard Areas m~y be protected by
flood control structu res,
I
Ejloundaries of the floodways were computed at cross sections and
ihterpolated between cross sections. The floodways were based on
~YdraUlic considerations with regard to requirements 'of the Federal
imergency Management Agency.

~IOOdWay widths in some areas may be too narrow to show to scale,
~IOOdWay widths are provided in the Flood Insurance Study Report

qoastal base flood elevations apply only landward of the shoreline,

dlevations reference marks are described in the Flood I nsurance Study
