NOTES

fhis map is for flood insurance and flood plain management
purposes; it does not necessarily show all areas subject to flooding
in the community or all planimetric features outside Special Flood
Hazard Areas.

Certain areas not in Special Flood Hazard Areas be protected
by flood control structures.

Boundaries of the flood ways were computed cross sections
and interpolated between cross sections. The flood ways were
based on hydraulic considerations with regard to requirements
of the Federal Emergency Management Agency..

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

Coastal base flood elevations apply only landward of the shoreline.

Elevation reference marks are described in the Flood Insurance
Study Report.

For adjoining map panels see separately printed Map Index.
