Ross <br />Re: 78-046 SOIL BORING & PERCOLATION <br />TESTS <br />Lot 5, Block 2, Farview Addtn. <br />Orono, Minnesota <br />Ms. Ross: <br />As you requested, we have recently conducted a soils investi- <br />gation consisting of one power auger boring and 12 percolation <br />tests, to determine the general soil and water conditions, and <br />to provide information relative to the soil absorptivity <br />rates. <br />The boring and percolation tests were taken at the locations <br />as shown on the attached sketch. Field locations were <br />determined by our crew, with reference to the staked property <br />corner. Surface elevations were referenced to a spike in a <br />large oak tree situated approximately 60 feet from the <br />northeast property corner. An elevation of 106.0 was given <br />for this bench mark. Initially, six percolation tests were <br />conducted on the lot on February 23, 1978. As 5 of the <br />initial tests indicated failing results, six additional <br />percolation tests were then conducted on February 28, as <br />requested. <br />INVESTIGATION METHODS: <br />The power auger boring was completed using a truck -mounted <br />power auger unit. The soil classifications and depth 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 strata changes are, thus, considered approximate. <br />CONSULTING ENGINEERS/SOILS AND MATERIALS <br />Test Borings • Fuundation Engineering and Recommendations • Inspection of Construction .
