ZONE AE Base flood elevations determined.

ZONE AH Flood depths of 1 to 3 feet (usually areas of
ponding); base flood elevations determined.

mined.

ZONE VE Coastal flood with velocity hazard (wave
action); base flood elevations determined.

This map is for use in administering the National Flood Insurance
Program; it does not necessarily identify all areas su bject to flood-'
ing, particularly from local drainage sources of small size, or all
planimetric features outside Special Flood Hazard Areas.

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

Boundaries of the flood ways were computed at 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.

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 this
map.

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

For adjoining map panels see separately printed Map Index.

See Map I ndex for Map Repository.

EFFECTIVE DATE OF COUNTYWIDE
FLOOD INSURANCE RATE MAP:

JUNE 4, 1987

Refer to Flood Insurance Rate Map Effective date shown below to
determine when actuarial rates apply to structures in zones where
elevations or depths have been established.
