TOPOGRAPHIC INFORMATION
USGS 7.5'Digital Elevation Model(DEM)
Source. United States Geologic Survey
EDR acquired the USGS 7.5'Digital Elevation Model in 2002 and updated it in 2006.The 7 5 minute DEM corresponds
to the USGS 1:24,000-and 1:25,000-scale topographic quadrangle maps.The DEM provides elevation data
with consistent elevation units and projection.
HYDROLOGIC INFORMATION
Flood Zone Data: This data was obtained from the Federal Emergency Management Agency(FEMA).It depicts 100-year and
500-year flood zones as defined by FEMA.It includes the National Flood Hazard Layer(NFHL)which incorporates Flood
Insurance Rate Map(FIRM)data and Q3 data from FEMA in areas not covered by NFHL

Date of Government Version:2003,2015
NWI. National Wetlands Inventory. This data,available in select counties across the country,was obtained by EDR
in 2002,2005 and 2010 from the U.S.Fish and Wildlife Service.

HYDROGEOLOGIC INFORMATION
AQUIFLOWR Information System
Source: EDR proprietary database of groundwater flow information
EDR has developed the AQUIFLOW Information System(AIS)to provide data on the general direction of groundwater
flow at specific points.EDR has reviewed reports submitted to regulatory authorities at select sites and has
extracted the date of the report,hydrogeologically determined groundwater flow direction and depth to water table
information.

STATSGO: State Soil Geographic Database
Source: Department of Agriculture,Natural Resources Conservation Service(NRCS)
The U.S.Department of Agriculture's(USDA)Natural Resources Conservation Service(NRCS)leads the national
Conservation Soil Survey(NCSS)and is responsible for collecting,storing,maintaining and distributing soil
survey information for privately owned lands in the United States.A soil map in a soil survey is a representation
of soil patterns in a landscape.Soil maps for STATSGO are compiled by generalizing more detailed(SSURGO)
soil survey maps.
SSURGO:Soil Survey Geographic Database
Source: Department of Agriculture,Natural Resources Conservation Service(NRCS)
Telephone: [phone]
SSURGO is the most detailed level of mapping done by the Natural Resources Conservation Service,mapping
scales generally range from 1:12,000 to 1:63,360.Field mapping methods using national standards are used to
construct the soil maps in the Soil Survey Geographic(SSURGO)database SSURGO digitizing duplicates the
original soil survey maps.This level of mapping is designed for use by landowners,townships and county
natural resource planning and management.
