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.

'-' 513 @----@ Base Flood Elevation Line; Ele- vation in Feet* Cross Section Line (EL 987l Base Flood Elevation in Feet Where Uniform Within Zone* RM7X Elevation Reference Mark *Referenced to the National Geodetic Vertical Datum of 1929 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 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. For adjoining map panels see separately printed Map Index.
