Box 66 <br />Crystal Bay, HN 55323 <br />Re: Richard W, Perry Jr. property <br />440 S. Willow Drire <br />Long Lake, MN 55356 <br />In regards to the concern about the wetlands area lying <br />west of the Perry property, I have analyzed the filling to be <br />done by Hr. Perry on his land. <br />Prior to the filling, runoff from his land entered a <br />ditch along Willow Drive, drained under his driveway through <br />a culvert, and ttien continued through • culvert under Willow <br />Drive to the wetlands west of his property. His proposed fill­ <br />ing will not alter this pattern of drainage since the ditch <br />and culverts will remain undisturbed. <br />Because of the proxiaiity to the wetlands, this filling was <br />also looked at in regards to the Minnehaha Creek Watershed Dis­ <br />trict requirements. Since this filled area will be replanted <br />with grass and trees, not hardcover, the runoff factor will re­ <br />main the same as that prior to the filling. Thus the quantity <br />of runoff wi|;l not be changed. <br />To prevent silt from entexdng the wetlands, a oovpl9 of <br />hay bales should be placed in the ditch during filling until the <br />grass cover is established. <br />If any questions arise, please contact me. <br />Sincerely I <br />Mark S, Gz>onberg, P.*^
