The proposed basins are maximized <br />to fill as much of the available space and provide the largest area for <br />evapotranspiration and infiltration. One-way inlets are again proposed to allow water <br />to flow in from the ditch but prevent backflow once water levels draw back down in <br />it. The ditch channel is not proposed to be shifted in this concept. <br />This concept results in the greatest pollutant removal and increase in floodplain <br />capacity. However, that comes at the cost of losing educational and recreational <br />opportunities with the basins. In addition, maximizing basin volume does not provide <br />much diversity in potential wetland improvements as much of it will consist of wet <br />marsh conditions. <br />Shenandoah Improvements Feasibility Report <br />City of Lino Lakes, MN <br />WSB Project No. 018901-000 <br />Page 10 <br />
