GEOTECHNICAL EXPLORATION AND REVIEW <br /> FOR <br /> 2013 STREET AND UTILITY IMPROVEMENTS <br /> ELK RIVER, MINNESOTA <br /> AET PROJECT NO. 26-00538 <br /> 1.0 INTRODUCTION <br /> We understand you are proposing to reconstruct portions of 3rd Street NW, Railroad Drive, <br /> Lowell Avenue, 4th Street NW, Orono Road, Gary Street, and 185th Avenue NW in Elk River <br /> Minnesota. To assist in planning and design, you have authorized American Engineering <br /> Testing, Inc. (AET) to conduct a subsurface exploration program at the site, conduct soil <br /> laboratory testing, and perform a geotechnical engineering review for the project. This report <br /> presents the results of the above services, and provides our engineering recommendations based <br /> on this data. <br /> 2.0 SCOPE OF SERVICES <br /> AET's services were performed according to our proposal to you authorized and dated November <br /> 19, 2012. The authorized scope consists of the following: <br /> • Fourteen(14) standard penetration test borings,to a terminal depth of 11 feet. <br /> • Soil laboratory testing consisting of sieve analysis tests and water content tests. <br /> • Geotechnical engineering analysis based on the gained data and preparation of this report. <br /> These services are intended for geotechnical purposes. The scope is not intended to explore for <br /> the presence or extent of environmental contamination. <br /> 3.0 PROJECT INFORMATION <br /> The portions of the previously listed streets planned for reconstruction are detailed on Figures 1, <br /> 2, and 3 in I Appendix A. These roadways will remain as residential streets, approximately 26 <br /> feet wide with concrete curb/gutter along the both sides, with the exception of 185'h Avenue NW. <br /> 185'h Avenue NW will have curb and gutter along the north side of the roadway and a rural <br /> section on the south side of the roadway. We understand final street grades will be within 2 feet <br />
