FLOODPLAIN <br /> <br />The development as proposed does not impede floodwaters in the floodplain. The <br />removal of sediment from storm water run-off is required by the city, prior to discharge <br />into the river. Retention of the net increase in run-off from development is also required. <br />Sedimentation is not allowed in the floodplain, but retention is. The development appears <br />to be allowing for the necessary sedimentation and retention outside of the floodplain. <br /> <br />Recommended Floodplain conditions: <br /> ~ That the City Engineer determines the adequacy of storm water <br /> sedimentation and retention for the development and that no sedimentation <br /> is allowed in the floodplain. <br /> <br />MINNESOTA DEPARTMENT OF NATURAL RESOURCES <br /> <br />City staff discussed the material contained in this memo with Patty Fowler, Area <br />Hydrologist for the DNR, on February 22, 2001. She was in agreement with staffs <br />recommendations. <br /> <br /> <br />
