SCHOELL & MADSON, INC. <br />Mr. Mike Gaffron 8 May 21,1997 <br />4.Protected Waters <br />a. DNR acting area hydrologist Peter Leedt identified the Ordinary' High Water mark on the <br />DNR protected water 837W as 976.67'. The DNR has requested that no weir be installed at the <br />outlet to stabilize water levels. The weir will not be installed. <br />Two boardwalks are proposed to cross over the north end along a narrow arm that angles <br />to the northeast. The boardwalk design will be 8' width, with a low profile wood construction. <br />These boardwalks are to accommodate both golfers and equipment. A permit application will be <br />submitted before June 1,1997. <br />At the request of the DNR, the mitigation area proposed to be constructed along the <br />southern edge of the protected water will not be attached to the protected w'ater. No other actions <br />affecting the basin are proposed. <br />0.Erosion Control <br />a. Measures for erosion control are according to MPCA specifications. Silt fencing will be <br />placed around all wetland areas (see grading plan) and will be placed so that flow cannot bypass <br />the ends. If slopes will be inactive for more than 45 days, slopes will be temporarily seeded. <br />When seeding occurs, the areas will be mulched until vegetation is established. All slopes <br />greater than 3:1 will be permanently or temporarily seeded, mulched and covered with a <br />woodfiber mat. <br />Very truly yours. <br />SCHOELL & MADSON, INC. <br />Marshal Braman <br />Senior Environmental Specialist
