VILLAGE OF TINLEY PARK, IL
Oak Park Avenue Reconstruction

In 2015, GEOCON Professional Services, LLC. (GEOCON) was retained by Robinson Engineering, Ltd., (REL) to conduct Preliminary Environmental Site Assessments (PESA) for a roadway improvement project on Oak Park Avenue, from 167th Street to 159th Street in Tinley Park, Illinois. The project area included numerous parcels along the roadway right-of-ways that included commercial, and residential properties


The assessment included site inspections of the project area and review of historical and geological information obtained from various local, state and federal sources in order to identify Recognized Environmental Conditions (RECs). The PESAs were conducted in a timely manner in general accordance with the Illinois Department of Transportation (IDOT) and Illinois State
Geological Survey (ISGS) PESA Manual, dated 1996, that was in effect at the time of the assessment. Several RECs were identified to be associated with the properties along and adjacent to the project area as documented in the PESA report.


The RECs in the project area were subsequently evaluated by GEOCON during the Preliminary Site Investigations (PSIs) that were conducted in accordance with IDOT standards in December 2017. The PSI work included the advancement of soil borings and the collection of soil samples for laboratory analytical testing at locations previously determined to contain RECs. The results of the laboratory analytical testing were compared to regulatory remediation objectives established by the Illinois Environmental Protection Agency (IEPA) for the various contaminants of concern as documented in the PSI report.
