August 8,2023 <br /> Itt Project 23-193 <br /> City Project#24-01 <br /> Fox Ridge Estates <br /> Ramsey,Minnesota <br /> 3. To provide a report of our findings including a summary of our findings with <br /> pavement thickness at each boring location as well as recommendations regarding <br /> earthwork, fill and compaction, subgrade preparation, and pavement design with <br /> an estimated design R-value. <br /> General Site Conditions: <br /> The project is located on the northeast side of the City of Ramsey, on the west side of <br /> Minnesota Highway 47 and south of Trott Brook. The project is an existing residential <br /> neighborhood. The site is fairly level, with slopes of 2-6 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 the site are <br /> sandy with few limitations for development of local streets. However, there are some marsh and <br /> silt loams mapped in the center of the site. <br /> B. Exploration Program <br /> Twenty- six (26) split-spoon soil borings were conducted on this project. The borings were advanced <br /> to depths of 10 feet using a 3 'A inch I.D. hollow stem auger. Samples were obtained every 2 1/2 feet <br /> using a 2-inch O.D. split-spoon sampler in accordance with the American Society for Testing and <br /> Materials (ASTM D1586). Standard penetration values (N-values)were obtained at each sample <br /> interval by driving the sampler into the soil using a 140-pound hammer falling 30 inches.After an <br /> initial set of 6 inches,the number of blows required to drive the sampler 12 inches is known as the <br /> standard penetration resistance or N-value.Where the sampler cannot be driven at least 6 inches by <br /> 50 blows of the hammer,the total number of blows as well as the distance driven is reported on the <br /> boring logs. <br /> Page 2 <br />
