SPECIAL FLOOD HAZARD AREAS INUNDATED
BY 100-YEAR FLOOD

ZONE A No base flood elevations determined.

ZONE AE Base flood 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.

NOTES

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

Areas of special flood hazard (lOO-year flood) include Zones A, AI-30,
AE. AH, AO, A99, V, VI-30 AND VE,

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
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.
Floodway widths are provided in the Flood Insurance Study Report,

Coastal base flood elevations apply only landward of the shoreline.

Elevations reference marks are described in the Flood Insurance Study
Report,
