Report of Geotechnical Exploration and Review <br /> 1105 Femdale Road West,Orono,Minnesota p��CpN <br /> June 21,2013 ENGINEERING <br /> Report No.01-05798 TESTING INC. <br /> , <br /> We drilled the boring using 3'/a-inch inside diameter hollow stem augers and by rotary drilling <br /> with drilling mud. We backfilled the boreholes to comply with cuzrent Minnesota Department of <br /> Health regulations. Refer to Appendix A for details on the drilling and sampling methods, the <br /> classification methods, and the water level measurement methods. <br /> 4.2 Laboratory Testing <br /> The laboratory test program included visual classification of the soil samples along with water <br /> content testing of selected samples. Additionally, a consolidation test was performed by Soil <br /> Engineering Testing on a sample collected at about 28 feet in Boring 2. The test results appeaz in <br /> Appendix A on the individual boring log adjacent to the samples upon which they were <br /> performed or on the test result sheets following the boring logs. <br /> 5.0 SITE CONDITIONS <br /> 5.1 Surface Observations <br /> The site is currently vacant and is generally surrounded on three sides by Lake Minnetonka and <br /> an existing single family home on the southeast. There is a relatively shallow excavation present <br /> from the removal of the previous house. The elevation at our borings ranged from 933.1 to 930.6. <br /> We measured the water level of Lake Minnetonka on May 10, 2013 at elevation 928.97. <br /> 5.2 Subsurface Soils/Geology <br /> At our borings, we found about 2 to 6%2 feet of fill or possible fill. Underlying the fill, we <br /> encountered predominantly coarse alluvial soils to depths of between about 20 to 28 feet, where <br /> swamp deposits were found to about 35 to 43 feet below grade. The swamp deposits consist of <br /> sapric peat and organic clay and had moisture contents ranging from 80%to 237%. <br /> Page 3 of 10 <br />
