. � <br /> LECEND <br /> � SPECIAL FLOOD HAZARD AREAS SUBJECT TO INUNDATION 1 <br /> BY THE 1 % ANNUAL CHANCE FLOOD <br /> The 1% annual chance flood (100-year flood), also known as the base flood, is the flood <br /> that has a 1% chance of being equaled or exceeded in any given year. The Special <br /> Flood Hazard Area is the area subject to flooding by the 1% annual chance flood. Areas <br />� of Special Flood Hazard include Zones A,AE,AH,AO,AR,A99, V, and VE. The Base <br /> Flood Elevation is the water-surface elevation of the 1% annual chance flood. <br /> ZONE A No base flood elevations determined. <br /> ZONE AE Base flood elevations decermined. <br /> ZONE AH Flood depths of 1 Yo 3 feet (usually areas of ponding); base flood <br /> elevations determined. <br /> ZONE AO Flood depths of 1 to 3 feet (usually sheet flow on sloping terrain); <br /> average depths determined. For areas of allwial fan flooding, velocities <br /> also determined. <br /> ZONE AR Area of Special Flood Hazard formerly protected from the 1 % annual <br /> chance flood by a flood control system that was subsequently <br /> decertified. Zone AR indicates that the former flood control system is <br /> being restored to provide protection from the 1% annual chance or <br /> greater flood. <br /> ZONE A99 Area to be protected from 1 % annual chance flood by a Federal <br /> flood protection system under construction; no base flood elevations <br /> determined. <br /> ZONE V Coastal flood zone with velocity hazard (wave action); no base flood <br /> elevations determined. <br /> ZONE VE Coastal flood zone with velocity hazard (wave acCion); base flood elevations <br /> determined. <br /> ���� FLOODWAY AREAS IN ZONE AE <br /> The floodway is the channel of a stream plus any adjacent floodplain areas that must be <br /> kept free of encroachment so that the 1% annual chance flood can be carried without <br /> substantial increases in flood heights. <br /> � OTHER FLOOD AREAS <br /> ZONE X Areas of 0.2% annual chance flood; areas of 1% annual chance flood <br /> with average depths of less than 1 foot or with drainage areas less than <br /> 1 square mile; and areas protected by levees from 1 % annual chance <br /> flood. <br /> � OTHER AREAS <br /> ZONE X Areas determined to be outside the 0.2% annual chance floodplain. <br /> ZONE D Areas in which flood hazards are undetermined, but possible. <br /> � COASTAL BARRIER RESOURCES SYSTEM (CBRS) AREAS <br /> \� \ OTHERWISE PROTECTED AREAS (OPAs) <br /> CBRS areas and OPAs are normally located within or adjacent to Special Flood Hazard Areas. <br /> Floodplain boundary <br /> Floodway boundary <br /> - - Zone D boundary <br /> •������������������• CBR$ dil(� C7PA boundary <br /> � Boundary dividing Special Flood Hazard Areas of different <br /> � `� � Base Flood Elevations, flood depths or flood velocities. <br /> —�M513�� Base Flood Elevation line and value; elevation in feet* <br /> (EL 987) Base Flood Elevation value where uniform within zone; <br /> elevation in feet* <br /> *Referenced to the National Geodetic Verticai Datum of 1929 <br /> A --�A Cross section line <br /> 23 - - - - - 23 Transect line <br /> 97°07'30", 32°22'30" Geographic coordinates referenced to the North American <br /> Datum of 1983 (NAD 83) <br /> 4276000nn 1000-meter Universal Transverse Mercator grid values,zone 15 <br /> 600000 FT 5000-foot grid ticks: Minnesota State Plane coordinate system, <br /> south zone (FIPSZONE 2203) Lambert Conformal Conic <br /> projection <br /> DX5510 X Bench mark (sZe explanation in Notes to Users section of <br /> this FIRM panel) <br /> O M1.5 River Mile <br /> MAP REPOSITORY <br /> Refer to listing of Map Repositories on Map Index <br /> EFFECTIVE DATE OF COUNTYWIDE <br /> FLOOD INSURANCE RATE MAP <br /> SEPTEMBER 2,2004 <br /> EFFECTIVE DATE(S)OF REVISIONIS)TO THIS PANEL <br /> For community map revision history prior to countywide mapping, refer to the Community <br /> Map History table located in the Flood Insurance Study report for this jurisdiction. <br /> To determine if flood insurance is avaiiable in this community, contact your insurance <br /> agent or call the National Flood Insurance Program at (800)638-6620. <br /> L�J <br /> MAP SCALE 1 " = 500 ' <br /> 250 0 500 1000 <br /> FEET <br />
