Vrctr AK Enpn ng <br />Re: 78-008A SOIL BORING & PERCOLATION <br />'TESTS <br />Lot 10, Block 1 <br />Farview Addition <br />Orono, Minnesota <br />As you requested, we have recently conducted one power auger <br />boring and ten percolation tests taken to determine the <br />general soil and water conditions, as well as to provide <br />information relative to the soil absorptivity rates for an <br />individual sanitary System being constructed at the above <br />referenced lot. Boring and percolation tests were taken at <br />the locations shown on the attached sketch. Field locations <br />were determined Sy our crew with reference to the staked <br />house location. Surface elevations were referenced to the <br />top of an iron at the northeast property corner with an <br />elevation at this point assumed equal to 100.0. <br />Initially, six percolation tests were conducted on the lot <br />on January 6, 1978. As some of the tests indicated failing <br />results, four additional percolation tests were conducted on <br />January 13, as you requested. <br />INVESTIGATION METHODS: <br />The power auger boring was completed using a truck -mounted <br />power auger unit. The soil classifications and depths shown <br />on the attached log were inferred from the soils brought to <br />the surface by the continuous flight feature of the auger. <br />The depth of s`rata changes are thus considered approximate. <br />CONSULTING ENGINEERS/SOILS AND MATERIALS <br />Test Borings • foundation Engineering and Recommendations a Inspection of Construction • Material Testing of Sods.
