The Geotechnical Exploration and Engineering Review was prepared by Northern Technologies, LLC (NTI), and consists of 6 boring logs (nominally drilled to 16 feet), a location diagram, and the geotechnical review and recommendations based on the interpretation of the boring logs. The Soil Boring Test Reports were prepared by Tradewell Soil Testing and consist of 12 pages of boring logs nominally drilled to 77 inches. This report did not include a map showing locations of the borings or a memo with the summary of the results and recommendations. Observations The NTI borings were placed as follows, borings 1, 2, 3 and 5 were placed in the proposed right- of-way. Borings 4 was placed in a proposed ponding area and boring 6 was placed in greenspace that previously was planned for a ponding area. All of the logs noted frost extended to 2 feet below grade. Boring 1 encountered sandy lean clay extending from the surface to 7 feet below grade. The soils to 14 feet were poorly graded sands with silt. The boring terminated at 15 feet in clayey sand. There are proposed ponding/infiltration areas on either side of the road adjacent to this boring. Borings 2, 3 and 5 found poorly graded sand or poorly graded sand with silt to a depth of 6 to 10 feet.
