Areas of 100-year shallow flooding where depths are between one (1) and three (3) feet; average depths of inundation are shown, but no flood hazard factors are determined. Areas of 1 OO-yearshallow flooding where depths are between one (1) and three (3) feet; base flood elevations are shown, but no flood hazard factors are determined. Areas of laO-year flood; base flood elevations and flood hazard factors determined. Areas of laO-year flood to be protected by flood protection system under construction; base flood elevations and flood hazard factors not -determined. Areas between limits of the 1 DO-year flood and 500- year flood; or certain areas subject to 1 GO-year flood- ing with average depths less than one (1) foot or where the contributing drainage area is less than one square mile; or areas protected by levees from the base flood. (Medium shading) Areas of minimal flooding. (No shading) Areas of undetermined, but possible, flood hazards. Areas of laO-year coastal flood with velocity (wave action); base flood elevations and flood hazard factors not determ ined.

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 the SpeCial Flood Hazard Areas (zones A and V) may be protected hy flood control structures. Coastal base flood elevations apply only landward of the shoreline shown on this map, For adjoining map panels, see separately printed Index to Map Panels.
