Spartz <br />Landview Landscaping <br />3670 Highway 7 <br />Excelsior, Minnesota 55331 GME Project No. 6721 <br />RE: Design recommendations for the block retaining wall <br />construction at the Vochko residence in Orono, Minnesota <br />Dear Mr. Spartz: <br />This report presents our design recommendations for the proposed <br />granite block retaining wall at the Vochko property in Orono. This <br />work was performed in accordance with your written acceptance of our <br />contract dated February 13, 1997. <br />Project Description <br />The property owner, Mr. Joe Vochko, has retained you to construct a <br />granite block retaining wall on the residential lot at 2925 Casco Point <br />Road in Orono. The existing wooden stairway and timber retaining walls <br />leading from the residence down to Lake Minnetonka have been removed. <br />You plan to reconstruct the stairway and retaining walls using cut Cold <br />Spring granite blocks and slabs. Each granite retaining wall block is <br />trapezoidal in shape with dimensions of 6-5/8 inches high by 10 inches <br />deep by 14 inches long. Each block weighs approximately 80 pounds. <br />We have attached with this report a copy of the site plan you prepared <br />showing the location of the wall and wall heights. The v/all will have <br />a maximum height of 5.25 feet in one corner of the walkway (designated <br />as the intersection of walls A and B) . From this corner, the wall will <br />slope downward to a minimum height of 1.84 feet (three blocks) . At the <br />tallest wall sections, you plan to anchor the blocks into the hillside <br />using conventional helical screw anchors fastened to the blocks with <br />threaded anchor bolts. The walls and stairway will be constructed at <br />the same location and same heights as the previous timber wall. <br />WILLIAM C. KWASNY, RE. <br />GREGORY R. REUTER. PE. <br />MARK D.
