The plan as <br />submitted is acceptable with provisions added for controlling the site runoff. <br />We have shown a preliminary layout for controlling the runoff with filter <br />drain outlets into Lake Minnetonka. This is not the only option but an ex­ <br />ample of what we would recommend. The developer should develop his own silta- <br />tion basin and outlet dontrols along with hydraulic calculations. The plan <br />should then be submitted to the Minnehaha Creek Watershed for approval. <br />The parking lot layout will allow for adequate movement through the site. We <br />have shown 25' turning radi on the plan which would be more than necessar/ for <br />the average vehicle. We would expect that most boat launchings will occur at <br />off peak hours and be completed by the operator. <br />The parking area.i should be surfaced with materials other than lime rock. The <br />rock surfacing creates a dust which silts up the grass ponding areas. The ^ <br />parking lots shoulc’ be constructed with a porous paving block if hardcover is <br />a concern. The parking lots should be paved with bituminous surfacing if the <br />hardcover is not a problem. <br />If you have any questions, please contact this office. <br />Yours very truly. <br />BONESTROO, ROSENE, ANDERLIK & ASSOCIATES, INC <br />Glenn R.
