Authorization to perform this work was your <br />acceptance of our contract addendum dated October 9, 1992. This report <br />concludes the scope of services described in our contract addendum. <br />Project Description <br />We understand that the slope along the Lake Minnetonka side of your <br />property failed during the "superstorm" of 1987. In 1988, the slope <br />was repaired by Outdoor Environments, a landscaping firm from Shakopee . <br />You stated the slope was stabilized by placement of geofabric. The <br />slope was reshaped and fill was placed with a small bulldozer. The <br />fill was common borrow and contained broken pieces of concrete from a <br />razed beach house. <br />During the heavy rains in the week of September 13 through 18, 199 2 <br />approximately 5 inches fell one night and caused a failure of the mid- <br />section of the slope. You stated that prior to the failure, the crest <br />of the slope had experienced some settlement. During our site visit on <br />October 8, 1992, we observed the failed area but did not see any <br />geofabric protruding from the exposed slope. You have subsequently <br />learned from the contractor that geofabric was not placed during <br />original slope repair. Also during our visit, we observed a tension <br />crack running parallel to the crest of the slope, approximately 5 feet <br />back from the edge. This crack traverses almost the entire length of <br />the slope . You stated that this crack is located at the approximate <br />boundary between the fill and the natural soil from the initial slope <br />repair. <br />Scope of services <br />For this phase of the project, you requested that we establish three <br />survey lines perpendicular to the slope in order to prepare cross <br />sections of the slope. After preparation of the cross sections, we <br />were to present preliminary design concepts for repair of the slope. <br />WILLIAM C. KWASNY, P.E. <br />GREGORY R. REUTER, P.E. <br />MARK 0 .
