Why CERCLIS? Most troublesome sites Spatially Environmentally Moderate record size Decent USEPA and IEPA file availability

Mapping Process Mapping order Counties in the Chicago area are being mapped first Other urban areas second Rural counties last

Mapping Process Data Collection Sources USEPA CERCLIS database IEPA files County tax record maps Aerial photographs USGS topographic maps

Mapping Process Data Collection Additional information Site property boundaries Local names and addresses State ID numbers

Mapping Process Coverage Creation ESRI’s ArcView 3.2 Shapefile Polygons and database Conversion to Arc 8.1 coverage

IDOT District 1

Will County, Illinois

Time Frame Currently two Chicago counties are completed Chicago area completed by Mid-2002 State completed by early 2003

Updates Coverage and Database will be updated on an annual/biannual basis Updates to include New sites Changes in site status Corrections to original coverage
