MN 55323 <br />Attn: Mike Gaffron <br />Re: 139-1326 Vayzata Country Club <br />Dear Mike: <br />. 4 i w <br />H <br />We observed the drainage in the Chevy Chase area on Tuesday. March 28, 1989. <br />The vater was flowing fairly heavy from the Vayzata Country Club across the <br />Simmons and Nelson property to Pond F. <br />There is approximatly 13 acres that flow through a swale on the Nelson <br />property. The swale is not adequate to handle the flow and should be <br />reconstructed. Improvement of the swale will allow water to flow more freelv <br />and eliminate the standing water on the Nelson and Simmons property. <br />Ve would recommend construction of a ponding area on the Vayzata Country Club <br />property. The pond would slow the rate of runoff but the volume of runoff <br />would not change significantly. If the swale on the Nelson property is <br />improved the overall drainage system for the area will be better. <br />The construction of a pond on the Vayzata Coui.try Club property «ould not <br />significantly affect the ground water elevation in the area. The water in the <br />pond would be there less then 6 hours for a 100 year storm event. <br />If you have any questions please contact this office. <br />Yours very truly, <br />BONESTOOO, ROSENE.
