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 Desctiption <br />We understand that the slope along the Lake Minnetonka side or ycur <br />prooerty failed during the "superstorm” of 1937. In 1933, the sicpe <br />was"repaired by Outdoor Environments, a landscaping firm from Shakopee. <br />You stated the slope was stabilized by placement or georabric. 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 i.rom a <br />razed beach house. <br />During the heavy rains in the week of September 13 through 13, 1992 <br />approximately 5 inches fell one night and caused a failure of the m-d- <br />section cf the slope. You stated that prior to the failure, the crest <br />of the slope had experienced some settlement. During our si^-e visia on <br />October 8, 1992, we observed the failed area but did not see any <br />qeofabric protruding from the exposed slope. You have subsequent-.'/ <br />learned from t.ne contractor t.hat geofabric was n^ placed curing <br />original slope repair. Also during our visit, we observed a tens-^-n <br />crack running parallel to the crest of the slope, approxi.mately <br />back from the edae. This crack traverses almost the entire length o- <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 />WILLIAM C. KWASNY.
