NOTES TO USERS 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. The community map repository should be consulted for possible updated or additional flood hazard information. ZONE X To obtain more detailed information in areas where Base Flood Elevation (BFEs) and/or floodways have been determined, users are encouraged to consult the Flood Profiles and Floodway Data tables contained within the Flood Insur- ance Study (FIS) report that accompanies this FIRM. Users should be aware that BFEs shown on the FIRM represent rounded whole-foot elevations. These BFEs are intended for flood insurance rating purposes only and should not be used as the sole source of flood elevation information. Accordingly, flood elevation data presented in the FIS should be utilized in conjunction with the FIRM for purposes of construction and/or floodplain management. 105007'30" 39050'37.5" I- IJJ IJJ ex: I-- CJ) l.lJ LU ....l QUEEN STREET I- IJJ IJJ cc I- CJ) h: ::J o (J 2 o CJ) cc IJJ a::: I- IJJ IJJ cc I- CJ) WE51 I-- IJJ IJJ cc I- CJ) IJJ cc o o ~ JEFFERSON €OUNTY UNINCORPORATED AREAS 080087 I 80TH WEST ~YENUE + Coastal Base Flood Elevation (BFEs) shown on this map apply only land- ward of 0.0' National Geodetic Vertical Datum (NGVD).

The Special Flood Hazard Area is the area subject to flooding by the 1 % annual chance flood. Areas of Special Flood Hazard include Zones A, AE, AH, AO, AR, A99, V, and VE. The Base Flood Elevation is the water surface elevation of the 1 % annual chance flood. ZONE A ZONE AE ZONE AH ZONE AO 4410000 M ZONE AR ZONE A99 ZONE V ZONE VE No base flood elevations determined. 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 sloping terrain); average depths determined. For areas of alluvial fan flooding, velocities also determined. Area of special flood hazard formerly protected from the 1 % annual chance flood event by a flood control system that was subsequently decertified. Zone AR indicates that the former flood control system is being restored to provide protection from the 1 % annual chance or greater flood event. Area to be protected from 1 % annual chance flood event bv a Federal flood protection system under construction; no base flood' elevations determined. Coastal flood zone with velocity hazard (wave action); no base flood elevations determined. Coastal flood zone with velocity hazard (wave action); base flood elevations determined. FLOODWAY AREAS IN ZONE AE The floodway is the channel of a stream plus any adjacent floodplain areas that must be kept free of encroachment so that the 1 % annual chance flood can be carried without substantial increases in flood heights. ZONE X ZONE X ZONE 0 ~~~ ~ ~ ~ ~~1 OTHER FLOOD AREAS Areas of 0.2% annual chance flood; areas of 1 % annual chance flood with average depths of less than 1 foot or with drainage areas less than 1 square mile; and areas protected by levees from 1 % annual chance flood. OTHER AREAS Areas determined to be outside the 0.2% annual chance floodplain. Areas in which flood hazards are undetermined, but possible.
