MN 55323 <br />Re; Robert Mack Berm <br />flic No. 129-05 COC <br />Plat No. 04-3034 <br />Dear Melanie. <br />\Vc base rcMcwcd the ptoposed grading plan for 15S0 6* Avenue North. The proposed improvements include <br />the construction of a berm along C R. 6 and associated site grading for a new home co.nstruction We ha\e the <br />follovs’ing comments with regards to engineering mar.ers; <br />• The ptoposed bciin is located along the south side of the pioposcd dri\e\\a>. The grading plan does <br />not indicate a ditch between the toe of the berm and the dmew ay. The grading plan should be revised <br />to include a ditch along the south side of the driveway <br />• We visited the site and disco\ ered a culvert parallel to C R 6 under the existing shared dnvew ay The <br />proposed berm appears to impede (low s to this culvert. The grading plan should be revised to show the <br />culvert, culvert inverts and a ditch directing drainage to this culvert. <br />• The plaits should include erosion and sediment control details, planting and restoration information, a <br />typical ditch section, and ditch restoration details. <br />If you have any questions please call me at (651) 604-4863. <br />Yours very truly. <br />BONESTROO.
