NOTES

This map is for use in administering the National Flood Insurance
it does not necessarily identify all areas subject to
from local drainage sources of small size, or all planimetric
Special Flood Hazard Areas.

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 interpo.
lated between cross sections. The floodways were based on hydraulic
considerations with regard to requirements of the Federal Emergency
Management Agency.

Floodway widths in some areas my be too narrow to showto 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.

Corporate limits shown are current as of the date of this map. The user
should contact appropriate community officials to determine If corporate
limits have changed subsequent to the issuance of the map.

For community map revision history prior to countywide mapping. see
Section 6.0 of the Flood Insurance Study Report.
