Report of Geotechnical Exploration and Review <br />Fox Street Improvements, Orono, Minnesota AMERICAN <br />July 29, 2016 ENGINEERING <br />Report No. 20-14448 TESTING, INC. <br /> <br /> <br /> <br />Page 1 of 12 <br />1.0 INTRODUCTION <br />The City of Orono (City) is proposing reconstruct portions of Fox Street over the next 3 <br />construction seasons. To assist 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 /> <br />2.0 SCOPE OF SERVICES <br />AET's services were performed according to our proposal to you dated June 1, 2016, which you <br />authorized on June 8, 2016. The authorized scope consists of the following: <br /> <br /> Drilling 24 standard penetration test borings each to a depth of 6 feet below grade. Due <br />to organic soils encountered at some locations, select borings were extended to depths up <br />to 16 feet below grade. <br /> Performing soil laboratory testing. <br /> Conducting a geotechnical engineering review based on the data and preparing this <br />report. <br /> <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 /> <br />3.0 PROJECT INFORMATION <br />Bolton & Menk, Inc., (BMI) on behalf of the City) is preparing a feasibility study for proposed <br />improvements to Fox Street between Old Crystal Bay Road South and Orono Orchard Road <br />South. The project will likely occur over 3 phases in subsequent years. The likely first phase, <br />which is located between Willow Drive South and Brown Road South, is a Municipal State Aid <br />(MSA) route. The west end of the project between Old Crystal Bay Road South and Willow <br />Drive South is slated for full reconstruction, per BMI. The east end of the project, from Brown <br />Road South to Orono Orchard Road South, may be reconstructed by reclaiming the existing <br />pavement and aggregate base (if present) for use as the new recycled aggregate base for the <br />reconstructed roadway. The three roadway sections are all planned to be constructed for a 9-ton
