SPECIAL FLOOD HAZARD AREAS INUNDATED
BY 100-YEAR FLOOD
ZONE A No base flood elevations determined.

ZONE AE Base floOQ elevations determined.

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

ZONE AO Flood depths of 1 to 3 feet (usually sheet
flow on sloping terrain); average depths
determined. For areas of alluvial fan flood-
ing, velocities also determined.

ZONE A99 To be protected from 100-year flood by
Federal flood protection system under
construction; no base elevations determined.

ZONE V

Coastal flood with velocity hazard (wave
action); no base flood elevations deter-
mined.

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

FLOODWAY AREAS IN ZONE AE

OTHER FLOOD AREAS

ZONE X Areas of SOO-year flood; areas of
100-year flood with average depths
of less than 1 foot or with drainage
areas less than 1 square mile; and
areas protected by levees from 100-
year flood.

OTHER AREAS

ZONE X Areas determined to be outside 500-
year flood plain.

ZONE 0 Areas in which flood hazards are
u ndeterm ined.

NOTES

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 floodways 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. Flood way widths are provided in the Flood I nsu ranee
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.
