se�ce�is,Zoig <br /> Pro�ect Is-a12 <br /> Slmvel Ready Project Site <br /> Peq�t Iakes,Minuesota <br /> General Site Conditlons: <br /> The proposed development site is approximately 90 acres on the south edge of town. The site is <br /> bounded by the new State Highway 371 bypass to the east and south,Derksen Road to the north <br /> and the Paul Bunyan Trail to the west. The north three fourths of the site is open,but the south one <br /> fourth of the site is lightly waoded. The site is relatively flat with slopes of 2 to 6 percent. <br /> Available Snbsarface Information: <br /> According to the Geologic Map of Minnesota,Quaternary Geology,prepazed by Howard C. <br /> Hobbs aad Joseph E. Goebel(1982,Minnesota Geological Survey),this site lies within an <br /> outwash unit associated with the Superior Lobe glaciation of Pleistocene,Late Wisconsinan age. <br /> The drift from this lobe consists of brown,noncalcareous till with clasts of igneaus and <br /> metamorp}uc rocks derived from pazent material in the Canadian Shield. <br /> According to the Soil Survey of Crow Wing County prepared by the Soil Conservation Service, <br /> the site lies within Greycalm loamy sand. These consist of sands and gravels formed in sandy <br /> outwash. Most of the individual soils mapped on this site are loamy sands that have no adverse <br /> limitations for development of commercial building sites and pavements. <br /> B. Ezploration Program <br /> Ten(10)spLtt spoon sofl borings were condncted on this project. The borings were planned to be <br /> advanced to depths ranging from jnst under 15 feet to 25 feet nsing a 3'/.inch I.D.hollow stem anger. <br /> Samples were obtained every 2'/:feet for the flrst 10 feet and every 5 feet theresfter nsing a Z-�inch <br /> O.D.spl�t spoon sampler in accordance with the American Society for T�ting and Materials(ASTM <br /> D158�. Standard genetration valnec(N-values)were obtained at e.ach sample interval by drlving the <br /> sampler into the soil asing a 140-ponnd hammer falling 30 inches. After an intdal set of 6 inches,the <br /> number of blows reqaired to drtve the sampler 12�tnches is known as the standard penetration <br /> res�istance or N-valne. Where the sampler can not be drYven at least 6 inches by 50 blows of the <br /> hammer,the total number of blows as well as the diistance driven is reported on the boring logs. <br /> Groundwater levels were noted during drilltng and�mmediately after comple�on.The holes l�s than <br /> 15 feet were back811ed with the anger cnttings. The deeper holes were sealed with benton�te gront in <br /> accordance with NIDH r�uirements. Some settlement of the bore holes may be ezpected. The <br /> borings were conduet�l with a truck mounted drill rig. The snrface elev�tions at�ch boring <br /> locadon were provided by WSN. <br /> Eznloration Resalts• <br /> The borings were conducted in an open field and encountered topsoil material consisting of dark, <br /> Page 2 <br />
