August 8, 2023 <br />ITT Project 23-192 <br />City Project 24-12 <br />Juniper Woods 1-3 Street Reconstruction <br />Ramsey, Minnesota <br />General Site Conditions: <br />The project is on Ute Street NW and Tonto Street NW, south of Alpine Drive in eastern <br />part of the City of Ramsey. The streets are in a single family residential neighborhood. <br />The site is relatively flat, with slopes of 2-4 percent. <br />Available Subsurface Information: <br />According to the Geologic Map of Minnesota, Quaternary Geology, prepared by Howard C. <br />Hobbs and Joseph E. Goebel (1982, Minnesota Geological Survey), this site lies within an <br />outwash unit not associated with a particular moraine. It is associated with the Des Moines <br />glaciation of Pleistocene, Late Wisconsinan age. The drift is derived from parent material in <br />North Dakota and Manitoba. <br />According to the Soil Survey of Anoka County prepared by the Soil Conservation Service, the site <br />lies within the Hubbard- Nymore Soil Associations. These consist of nearly level to gently sloping, <br />excessively drained soils that are sandy throughout. The individual soils mapped on this site are <br />sandy and have few limitations for development of local roads and streets. <br />B. Exploration Program <br />Ten (10) split -spoon soil borings were conducted on this project. The borings were advanced to <br />depths of just under 15 feet to 20 feet using a 3 1/4 inch I.D. hollow stem auger. Samples were <br />obtained every 2 1/2feet for the first 10 feet and every 5 feet, thereafter, using a 2-inch O.D. split - <br />spoon sampler in accordance with the American Society for Testing and Materials (ASTM D1586). <br />Standard penetration values (N-values) were obtained at each sample interval by driving the sampler <br />into the soil using a 140-pound hammer falling 30 inches. After an initial set of 6 inches, the number <br />of blows required to drive the sampler 12 inches is known as the standard penetration resistance or <br />N-value. Where the sampler cannot be driven at least 6 inches by 50 blows of the hammer, the total <br />number of blows as well as the distance driven is reported on the boring logs. <br />Groundwater levels were noted during drilling and immediately after completion. The holes were <br />backfilled with the auger cuttings and patched with bituminous cold patch. Some settlement of the <br />bore holes may be expected. All the borings were conducted with a truck mounted rig. <br />Exploration Results: <br />The pavement was cored at each boring location prior to drilling the boring. The cores were <br />obtained to get accurate pavement thickness. Photos of each core are included in appendix 1. <br />Page 2 <br />
