<br /> Weaver Consultants Group <br /> <br />2 <br /> <br />2 PROJECT INFORMATION <br />2.1 Project Description and Location <br />We understand that the city of South Bend is considering the construction of a new storm water <br />drain beginning near the intersection of Lindenwood Drive West and Laurel Wood Drive North <br />and ending at Laurel Drive and Auten Road in South Bend, Indiana. The location of the project is <br />shown on a Site Location Plan (Figure 1) in the Appendices. The new storm sewer pipe is <br />anticipated to be established at a maximum depth of about 5 feet below the existing ground <br />surface. Other details of the storm sewer such as the pipe diameter and outlet structure are <br />unknown. Given the type of project, we anticipate that the sewer will be constructed using cut <br />and cover techniques. We also understand that dry wells are being considered to manage the <br />collected runoff. Details such as size, location and dep th of the dry wells is unknown. <br />For design of the proposed storm sewer, a subsurface exploration program consisting of four test <br />borings was performed. The number, depth and general locations of the soil borings were chosen <br />by Weaver Consultants Group (WCG) based on the project plan provided by McCormick <br />Engineering, LLC. The boring plan was to perform the borings to a depth of 15 feet below the <br />existing ground surface. However, due to the subsurface conditions, two of the four boring were <br />extended to a deep as 25 feet below the ground surface (bgs). The borings were located, in the <br />field, by a representative of WCG referencing existing site features. The approximate locations of <br />the borings are provided on a Boring Location Plan (Figure 2) in the Appendices. <br />2.2 Site Description <br />The road and ground surface along the planned alignment are relatively flat. A ditch which <br />increases in depth from east to west is located along the south side of Auten Road. At the time <br />of our field activities, there was no water in the ditch. Based on the utility location markings <br />provided by others, numerous below grade utilities including a high-pressure gas main, fiber optic <br />lines, water mains, and others exist along the alignment.
