The boring and percolation <br />tests were taken at the locations as directed by you and as <br />shown on the attached sketch. Field locations were refer- <br />enced to the proposed house location. Surface elevations <br />were interpolated from the topographic site plan which had <br />been provided for our use previously. <br />' With the exception of percolation test P-5, all of the tests <br />resulted in percolation rates above the recommended limits. <br />You, therefore, indicated that additional percolation tests <br />I' be performed. Based on the results of the soil boring, it <br />was then rcommended by us that the additional percolation <br />tests be conducted further to the southwest of the proposed <br />' drainfi d are These additional tests were then conducted <br />on May 7/ and (8,,` 1977, at locations as indicated on the <br />attache sketch-. <br />' INVESTIGATION METHODS: <br />The power auger Loring was completed using a CME-45 truck <br />' mounted power auger unit. The soil classifications and <br />depths, as shown on the attached log, were inferred from the <br />soils brought to the surface by the continuous flight feature <br />of the auger. The depth of strata changes are, thus, considered <br />' somewhat approximate. <br />' CONSULTING ENGINEERS/SOILS AND MATERIALS <br />Fist Sonngs - Foundation Engineering and Recommendations - Inspection of Construction - Material Testing of Sods Concrete and Budding Components <br />
