' INTRODUCTION <br /> t This geotechnical exploration and excavation slope study was performed by SKS Engineers, <br /> LLC (SKS) at the location for the new Vulcan Waterline Pipeline project located in Decatur, <br /> 1 Macon County, Illinois. Mr. Robert Weil, of City of Decatur (Public Water District) authorized the <br /> work on June 18, 2024. The work was performed in accordance with our standard procedures <br /> ' for such geotechnical investigations. <br /> This geotechnical report has been prepared to present the results of our field and laboratory <br /> tests, our engineering review, and project recommendations. The purpose of this report is to <br /> provide recommendations for the safe and economical construction of the proposed project. It <br /> should be noted that our work is intended for geotechnical purposes only. The soil borings were <br /> ' not intended for use as environmental borings. <br /> ' Our work was performed in general accordance with current ASTM standards, accepted <br /> geotechnical engineering procedures, and within the limitations and general conditions for soil <br /> ' and foundation investigations governing this type of work, as described in Appendix A. <br /> ' SITE DESCRIPTION <br /> ' The portion of the pipeline is located along S. Lincoln Park and S. Franklin Road in Decatur, <br /> Macon County, Illinois. A site location map is included with a boring location plan, which is a <br /> ' portion of a satellite view for this part of Macon County, Illinois. This plan is included in Appendix <br /> B. <br /> t <br /> The topography of the pipeline site varies somewhat. In general, the site is relatively flat and <br /> goes across the Sangamon River. This topography is typical for most of Macon County. It is <br /> the result of glaciation and later, weathering. <br /> Geotechnical Exploration for Sanitary Pipeline <br /> ' New Vulcan Waterline Pipeline, Decatur, Macon County, Illinois <br /> SKS Project No. 12-418885 Page 1 <br />
