Olson <br />Re:139-1005 French Creek Subdivision <br />Pond Grading <br />Dear Mike: <br />We have reviewed the proposed grading of Pond A on the French Creek <br />Subdivision. The grading will not have a significant effect on the system <br />hydraulics or the water quality of the watershed. <br />The grading of the pond area has been requested to eliminate the existing <br />algae problem and to provide a duck nesting area. The design of the pond is <br />such that there will be little effect on the algae problem. <br />The ponds greatest asset at the present time '• . one of collecting silt and <br />debris from the upstream watershed. This will "ot change with the proposed <br />grading. We would recommend that a timber baffle outlet structure be <br />constructed to eliminate floating debris from entering the downstream <br />watershed. We would also recommend some type of silt fence be constructed at <br />the outlet during construction. <br />The pond is located high up in the drainage basin and away from Lake <br />Minnetonka so in that respect does not have a direct impact on the lake. We <br />would recommend that the proposed grading plan be approved. <br />Yours very truly. <br />BONESTROO, ROSENE, ANDERLIK & ASSOCIATES, INC. <br />Glenn R. Cook <br />GRC/kas <br />3370d
