The boring locations are shown on the attached sketch. <br />Prior to commencing with our subsurface exploration activities, we coordinated the clearing of the soil <br />boring of underground utilities through Gopher State One Call. <br />B.Results <br />B.1.Exploration Logs <br />B.1.a.Log of Boring Sheets <br />Log of Boring sheets for our penetration test borings are included in the Appendix. The logs identify and <br />describe the geologic materials penetrated, the results of penetration resistance and laboratory tests <br />performed on penetration test samples retrieved from them, and groundwater observations. <br />Strata boundaries were inferred from changes in the penetration test samples and the drill auger <br />cuttings. Because sampling was not performed continuously, the strata boundary depths are only <br />approximate. The boundary depths likely vary away from the boring locations, and the boundaries <br />themselves may also occur as gradual rather than abrupt transitions. <br />B.1.b.Geologic Origins <br />Geologic origins presented for each stratum on the Log of Boring sheets are based on the soil types, <br />blows per foot, and available common knowledge of the geological history of the site. Because of the
