Green <br />Trees on Tanager Lake, Orono. MN <br />Dear Mr. Vergcyle: <br />We were authorized to perform a geotechnical investigation for the above referenced <br />nroiect The purpose of the investigation was to gather information to assist in the evalua lo <br />of soil and ground water conditions relative to foundation support and construction of the <br />hLslear fhe bluff. Two standard penetration borings were perforrned on the TOan of <br />this investigation. The intetpretation of the results ate contained in this letter. The boring <br />locations were selected in the field by your builder Steve Streeter and our representative. <br />METHODOLOGY <br />The borings were performed with a truck mounted CME 55 rig, using 4 1/4" inside <br />diameter hollow stem auger. Soil samples were collected using a 2" outside diameter steel <br />split barrel sampler. The sampler is attached to drill rods and lowered down inside the <br />auger The sampler is then driven into the ground ahead of the auger using a 140 pound <br />haraner with a 30 inch drop. The sampler is driven 2 feet with the number of harnmci <br />blows recorded in 6 inch increments. The blows from the first 6 inches and last 6 <br />inches are disregarded. The blows from the intermediate 1 foot are reported on boring <br />log and arc and indication of the soil strength characteristics. Samples were taken at 2 1/2 <br />foot intervals to the termination depth of the borings. A portion of each sample was sealed <br />in a glass jar. <br />Soil identincacion was performed using ASTM D:2488 (Visual-Manual Procedures). <br />Preliminary classification was performed in the field, with final deierminaiion made in the <br />laboratory The samples will be retained and are available for your e.samination. <br />The holes were probed immediately after the auger was withdrawn to check for the <br />presence of groundwater. The holes were then backfilled with a tiiLcture of benioniie and <br />drill cuttings. <br />APP ipm ATIVE ACTICN . EGUAL CP=CP-UMlTV EMPLOYE*^
