..� FML, Inc. STS Project 93589 August 28, 1985 4- ANALYSIS AND RESULTS Subsurface Exploration and Laboratory Testina Procedures The soil borings performed for this project were drille d using a rubber tire mounted all -terrain vehicle auger type drill rig which 1 used continuous flight hollow stem augers to advance the borings to full depth. g p Representative soil samples were obtained using the 1 split -barrel sampling procedure in general conformance with ASTM specification D 1586. A continuous field log of the drilling procedures used and soils encountered was maintained by the drill 1 crew. The drillingand sampling mpling procedures are described in more detail in the Appendix of this report. The soil samples recovered in the drilling and sampling operations were ret urned to our laboratory for further visual examination and classification and j laboratory testing. The sample classification and testing procedures as well as procedures regarding field logs, laboratory i data sheets and samples are also described in more detail in the -1 Appendix. a Site Conditions The site is of relatively level to gently sloping terrain located at the southeast quadrant of the intersection of Highway 36 and Victoria Street in Roseville, Minnesota. On the western boundary of the site, the ground surface slopes up to the Victoria Street bridge, crossing Highway 36. In the southwest corner of the property, a portion of the former borrow pit approximately 30-ft deep is being filled with soil and construction debris by the City Of St. Paul. The filled portion of the site has been graded relatively flat at elevation of approximately 935 to 937 ft. The natural terrain to the east is also relativelyflat lying, and includes some trees and bushes. Ground surface elevations range from approximately 930 ft to 938 ft USGS. The site is surrounded on the east and south by an existing residential neighborhood. 1 1 1 1 1 d n 77 [J 1 1 1 1 i
