Will the project change the number or type of watercraft on any water body? <br />If yes, indicate the current and projected .watercraft usage and discuss any potential. <br />overcrowding or conflicts with other uses. <br /> !11 No <br /> <br />Give the acreage to be graded or excavated and the cubic yards of soil to be moved. <br />Describe any steep slopes 0r highly erodible soils and identify them on the site map. <br />Describe any erosion and sedimentation control measures to be used during and after <br />project construction. <br />Acres 170 Cubic Yards 600,000 CY <br /> <br /> The proposed development is si~ated west of the To~ Center. h general, the proposed site gently slopes towards <br /> the sou~. The sto~ water mnogis routed ~om the no~h to the south and eventually to the Mississippi River via <br /> the Ci~'s sto~ sewer system. Proposed development sto~ water management system(s) will meet anger exceed <br /> MPCA mquiremenB. Proposed disch~ge flow rates will be eq~l to or le~ than the existing flow rates. <br /> As pa~ of the plains process, an Erosion and Sediment Con=el PI~ ~d a Sto~ Water Polluhon Prevention Plan <br /> (SWPPP) will be submitted for re~ew ~d approval. The developer mint also obtain and comply with National <br /> Pollutant Disch~ge Elimination System ~PDES) pe~it requirements, including the SWPPP. <br /> L~d disturbing a6tivities'shall occ~ in incremen~ so that adeq~te BMP control c~ be provided throughout all <br /> ph~es of coat,etlon. ~ all are~ ou~ide of the co~trucdon area, the existing vegetation shall be prese~ed to <br /> pro,de a pe~ent vegetative cover. During construction, silt fences, sto~ water b~ins md seeding disturbed <br /> slopes will be udlized ~ soon ~ possible to limit the ~o~t of sediment leaMng the site. Silt fences will be <br /> installed do~ ~ient ~om cons~cfion ~e~ ~d wherever moff ~om the cons~ction ~ea discharges ~om the <br /> site.

Soils ~om the cut are~ will <br /> be ~ed in the fill ~e~ to cmate'a balanced overall sim. B~s will be ~ed for erosion control 'including pon~, <br /> topsoil re-spreM, ~festablishment, silt fences, rock cons~cfion on,ce <d erosion control mB or wood fiber <br /> bi,cB. <br /> According to the Soil S~ey of ~oka Count, soils on the site ~e DnA (Die,nan sandy 1o~ 0 to 2 percent. <br /> slopes), Dp (Duelm lo~y come s~d), H~, H~, HuC (Hubb~d come sand, 0 to 2 pement slopes, 2 to 6 <br /> percent slopes, grid 6 to t2 percent slopes, respectively),' Is (~an sandy lorn), Ma (Markey muck), and NrD <br /> ~ore loamy coame sand, t2 to 25 percent). ~e distribution of these soil ~es is shown in Fibre 4. Some of <br /> these soils have slopes greater than 12%, which is the definition of steep slopes. ~1 proposed slopes ~e less than <br /> 6%, The only highly credible soil on the site is NrD ~ore lo~y coarse sand, 12 ~ 25 percenO, which is <br /> located on the no~he~t side ofth~ sim and ~coun~ for a yew'small posen of the ~ite estimated at 5 acres). <br /> <br /> a.
