Boulder walls are acceptable provided they are less than 4 feet <br />in height and if tiered, no less than two times the heigh apart The plans meet this criteria <br />and appear acceptable from an engineering standpoint Erosion control should be installed <br />along the shoreline prior to the work to protect the lake. <br />Please contact me at this office if you have any questions regarding this matter. <br />Yours very truly, <br />BONESTROO, ROSENE, ANDERLIK & ASSOCIATES, INC. <br />Shawn D. Gustafson, P.E. <br />2335 West Highway 36 • St. Paul, MN 55113 • 612*636*4600
