PROJECT INFORMATION <br /> The project site is a slide area occurring along the south bank of a meander in the Wild Rice River, <br /> roughly paralleling Cass County Road 14. We understand the slide is actually encroaching into the <br /> north edge of the county road. We estimate the distance from the edge of the road to the center <br /> line of the river is on the order of 150 feet. The road embankment slopes downward toward the <br /> river through a grassy area for the first 30 to 50 feet. The remainder of the slope toward the river is <br /> heavily wooded. No topographic survey is available to us,at this time. <br /> B. SCOPE OF SERVICES <br /> Field Program —We propose to perform four soil test borings at this site, in order to characterize <br /> the soil and ground water conditions, and to determine the nature of the slide. Three of the <br /> borings would be taken within the ditch slope on the north side of the county road, with one boring <br /> taken on the south side of the road. The center boring on the north side would be extended to <br /> dense glacial drift, estimated to be on the order of 100 feet below the surface grade. The other <br /> three borings would be taken to a depth of 50 feet. <br /> A topographic survey of the affected area should be performed by others, as an aid to our <br /> analysis. <br /> MTL—A Terracon Company 4102 7r"Avenue North Fargo,North Dakota 58102-2923 <br /> P 1701]282 9633 F [701]282 9635 terracon,com <br /> Geotechnical • Environmental i Construction Materials • Facilities <br />
