The letter report summarizes the results of <br />our Investigation. <br /> Location <br /> <br />The site is located on the Sheyenne River just south of the Norman Lutheran Church about 3 miles <br />northeast of Kindred, ND. <br /> General Conditions <br /> <br />The streambank on the south side of 52nd St. SE near Norman Lutheran Church is eroding due to <br />waters from the Sheyenne River. From site observation, the failure appears to be a surface failure <br />(not a deep rotational failure) undergoing gradual erosion rather than a larger slide along a slip <br />plane. Left unchecked, the problems could continue to grow and cause greater problems. On the <br />site, there are several larger trees ranging between 1’-1.5’ in diameter (see Photo 2), as well as a <br />few larger and many smaller trees and brush. The river was approximately 60’ wide and the top of <br />ice elevation was 917.87 at the time of survey on February 13, 2012. The river bottom ranges <br />between elevation 908 and 913 in the project area. The FEMA 100-year flood elevation is 933.5 <br />and the recorded high water in nearby locations is approximately 935. The finished floor elevation <br />on the southern portion of the church is 939.05. (All elevations are in reference to the NAVD 88 <br />datum.) <br /> <br />There are concerns about parts of the failure encroaching onto 52nd St. SE and further onto church <br />property. Portions of the eroded bank are now less than 10’ from the road and could soon cause
