1.6 Locations and Elevations <br /> The boring Iocations were selec by Mr.Alex Ugorets. The approximate locations of the <br /> borings are shown on the "So�Boring Location Sketch" provided in Figure 1 in the <br /> appendix. . <br /> Ground surface elevations at tl�e boring locations were obtained by HGTS using GPS <br /> measuring equipment. Elevatiohs were based on MN County Coordinates System mean <br /> sea level using the GEOID09(Cqnus)model. GPS coordinates at the boring locations are <br /> provided in Figure 2 in the App�ndix. <br /> 2.0 FIELD PROCEDURES <br /> Four(4)standard penetration te5t borings were advanced on Apri115,2016 by HGTS with <br /> a rotary drilling rig, using Continuous flight augers to advance the boreholes. <br /> Representative samples were o�ed from the borings,using the split-barrel sampling <br /> procedures in general accordan�ce with ASI'M Specification D-1586. In the split-barrel <br /> sampling procedure,a 2-inch 0.�.split barrel spoon is driven into the ground with a 140- <br /> pound hammer falling 30 inch . The number of blows required to drive the sampling <br /> spoon the last 12 inches of an 1 inch penetration is recorded as the standazd penetration <br /> resistance value,or"N"value. e results of the standard penetration tests are indicated <br /> on the boring log. The samples�tere sealed in containers and provided to HGTS for testing <br /> and soil classification. <br /> A field log of each boring was p�epared by the HGTS drill crew. The logs contain visual <br /> classifications of the soil materi�ls encountered during drilling, as well as the driller's <br /> interpretation of the subsurface onditions between samples and water observation notes. <br /> The final boring logs included th this report represent an interpretation of the field logs <br /> and include modifications based on visual/manual method obsexvation of the samples. <br /> The soil boring logs, general ' ology for soil description and id�tification, and <br /> classification of soils for engine ' g pur�oses aze aLso included in the appendix. The soil <br /> boring logs identify and desc be the materials encountered, the relative density or <br /> consistency based on the Standa#d Penetration resistance(N-value,"blows per foo�')and <br /> groundwater observations. <br /> T'he strata changes were inferred from the changes in the samples and auger cuttings. The <br /> depths shown as changes betw�een strata are only approximate. The changes are likely <br /> transitions,variations can occur ond the location of the boring. <br /> 3.0 RESULTS <br /> 3.1 Soil Conditiona <br /> In general,borings SB-1 thru SB- encountered about 2 to 6 inches of bituminous over 4 to <br /> 8 inches of aggregate base und lain.by silty sand and sandy lean clay glacial till soiLs to <br /> the termination depths of the ' gs.
