DeBenedet, PEE. <br />Engineering Consultant <br />(612) 636-9083 <br />January 31, 1980 <br />Richard Ernst <br />2100 Silver,,Lake Road <br />New Brightoh, MN 55112 <br />,- <br />Dear Dick: <br />At the January meeting of the New Brighton park board, we <br />presented our drainage for ,,Park Place. The board heard our pre- <br />. sentation and asked us to prepare drawings for six alternates <br />for drainage to be considered at their next meeting. The neigh- <br />borhood will be invited to the next meeting to provide input as <br />to the intended use of the park. <br />The six alternatives are briefly discussed below. <br />1. Grade the entire park site to a low elevation for <br />stormwater detention. Slope the bottom at a 1% <br />slope from east to -~rest side. <br />This alternative will meet all criteria for storm- <br />water control set forth by the Llatershed District. <br />It will have r~inimal impact on the usefulness of <br />the park. It may involve substantial cost for <br />excavation but you indicate that others are willing <br />to remove the sand at no cost to you. <br />2. Provid~,25%. of ~the required ponding in the park and <br />75% in tF~ rest of the development. <br />This--requires that most of the back yards and other <br />green areas by the homes and condominiums be used for <br />...ponding. This is highly undesirable. It would de- <br />grade the development and result in wet basements. <br />kx <br />
