ZONE AE ZONE AH Base flood elevations determined. Flood depths of 1 to 3 feet (usually areas of ponding); base flood elevations determined. Flood depths of 1 to 3 feet (usually sheet flow on slo,ping terrain); average depths determined. For areas of alluvial fan flood- ing, velocities also determined. ~ONE AO 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 500-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.

Al.30 AE. AH, AO, A99, V, Vl.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, JThe floodways were based on hydraulic considerations with regard to requirements of the Federal Emergency Management Agency, Floodway widths in some areas may be too narrdw to show to scale, Floodwav widths are provided in the Flood Insurance Study Report, Coastal base flood elevations apply only landward of the shoreline.
