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 lOO-year flood by Federal flood protection system under construction; no base elevations determined.

FLOODWAY AREAS IN ZONE AE OTHER FLOOD AREAS ZONE X Areas of 5DD-year flood; areas of 1DD-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 10.0.- year flood.

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 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 referenc.e marks are described in the Flood Insurance Study Report. For adjoining map panels see separately printed Map Index.
