Green Company <br />1326 Energy Park Drive <br />St. Paul, MN 55108 <br /> <br />Re: <br /> <br />Subsurface Exploration for the 2003 Street Improvements at Fourth Street Between Rush Avenue <br />and Morton Avenue in Elk River, Minnesota; STS Project 98934 <br /> <br />Dear Mr. Wallick: <br /> <br />We have performed a subsurface exploration and geotechnical engineering analysis for this road <br />reconstruction project in Elk River. This work was performed based on the scope of services defined in <br />our proposal dated October 17, 2002. This work was authorized by Mr. Paul Wallick on October 22, <br />2002, acting on behalf of the City of Elk River. <br /> <br />Project Description <br /> <br />You propose to reconstruct Rush, Quinn, Oxford, Norfolk, and Morton Avenues, and the section of Fourth <br />Street between Rush and Morton Avenues. New watermain will be installed in these streets at <br />approximately 7-1/2 foot depth, followed by installation of new pavements. Little or no grade changes are <br />anticipated. <br /> <br />Project Scope and Purpose <br /> <br />The purposes of this exploration are to perform a subsurface exploration and testing program consisting <br />of seven soil borings to 10 foot depths, and to record the thicknesses of pavement and base course <br />penetrated by the borings. We were to describe the soil and groundwater conditions encountered in our <br />exploration, present recommendations for soil compaction, and provide an estimated stabilometer <br />R-value for pavement thickness design. <br /> <br />Procedure <br /> <br />Howard R. Green Company selected the number of borings and the boring locations. A Howard R. <br />Green survey crew staked the borings in the field. We drilled the borings on November 14, 2002 with a <br />truck-mounted Diedrich D-50 drill rig operated by a two person crew. We followed conventional drilling <br />and soil sampling procedures. <br /> <br />The soil samples recovered were examined in our laboratory by an engineer, who prepared soil boring <br />logs. <br /> <br />100-LH.8 <br /> <br /> <br />
