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 /> Pro�ect 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 , 1992 <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. THOMAS PAUL VENEMA,P.E.
