PHYSICAL SETTING SOURCE RECORDS SEARCHED <br /> 111 TOPOGRAPHIC INFORMATION <br /> USGS 7.5'Digital Elevation Model(DEM) <br /> Source:United States Geologic Survey <br /> EDR acquired the USGS 7.5'Digital Elevation Model in 2002 and updated it in 2006.The 7.5 minute DEM corresponds <br /> to the USGS 1:24,000-and 1:25,000-scale topographic quadrangle maps.The DEM provides elevation data <br /> with consistent elevation units and projection. <br /> 111 Scanned Digital USGS 7.5'Topographic Map(DRG) <br /> Source: United States Geologic Survey <br /> A digital raster graphic(DRG)is a scanned image of a U.S.Geological Survey topographic map.The map images <br /> are made by scanning published paper maps on high-resolution scanners.The raster image <br /> is georeferenced and fit to the Universal Transverse Mercator(UTM)projection. <br /> HYDROLOGIC INFORMATION <br /> Flood Zone Data: This data,available in select counties across the country,was obtained by EDR in 2003&2011 from the Federal <br /> Emergency Management Agency(FEMA). Data depicts 100-year and 500-year flood zones as defined by FEMA. <br /> I NWI: National Wetlands Inventory. This data,available in select counties across the country,was obtained by EDR <br /> in 2002,2005 and 2010 from the U.S. Fish and Wildlife Service. <br /> HYDROGEOLOGIC INFORMATION <br /> AQUIFLOWR Information System <br /> Source: EDR proprietary database of groundwater flow information <br /> EDR has developed the AQUIFLOW Information System(AIS)to provide data on the general direction of groundwater <br /> flow at specific points. EDR has reviewed reports submitted to regulatory authorities at select sites and has <br /> extracted the date of the report,hydrogeologically determined groundwater flow direction and depth to water table <br /> information. <br /> GEOLOGIC INFORMATION <br /> Geologic Age and Rock Stratigraphic Unit <br /> Source: P.G.Schruben,R.E.Arndt and W.J. Bawiec,Geology of the Conterminous U.S.at 1:2,500,000 Scale-A digital <br /> representation of the 1974 P.B.King and H.M. Beikman Map, USGS Digital Data Series DDS-11 (1994). <br /> STATSGO: State Soil Geographic Database <br /> i Source: Department of Agriculture, Natural Resources Conservation Services <br /> The U.S. Department of Agriculture's(USDA)Natural Resources Conservation Service(NRCS)leads the national <br /> Conservation Soil Survey(NCSS)and is responsible for collecting,storing,maintaining and distributing soil <br /> survey information for privately owned lands in the United States.A soil map in a soil survey is a representation <br /> of soil patterns in a landscape.Soil maps for STATSGO are compiled by generalizing more detailed(SSURGO) <br /> soil survey maps. <br /> SSURGO:Soil Survey Geographic Database <br /> Source: Department of Agriculture,Natural Resources Conservation Services(NRCS) <br /> Telephone: 800-672-5559 <br /> SSURGO is the most detailed level of mapping done by the Natural Resources Conservation Services, mapping <br /> scales generally range from 1:12,000 to 1:63,360. Field mapping methods using national standards are used to <br /> construct the soil maps in the Soil Survey Geographic(SSURGO)database.SSURGO digitizing duplicates the <br /> original soil survey maps.This level of mapping is designed for use by landowners,townships and county <br /> natural resource planning and management. <br /> I <br /> I <br /> TC4378337.2s Page PSGR-1 <br />
