requirements of the City's Surface Water Management Plan will be adhered to while <br /> inspecting and performing all stormwater facilities maintenance work. <br /> 4) Stormwater Facilities Maintenance Plans <br /> a) Stormwater Ponds <br /> i) State Ponds <br /> State-owned stormwater ponds are managed by the Minnesota Department of <br /> Transportation. <br /> ii) County Ponds <br /> County-owned stormwater ponds are managed by the Anoka Highway Department. <br /> iii) City Ponds <br /> City-owned stormwater ponds and wetlands are managed by the City to provide <br /> storage for surface water runoff and to allow for free flow of stormwater through <br /> the system. These ponds also reduce peak stormwater flows, promote settling of <br /> suspended pollutants and removal of Phosphorus, and reduce velocities <br /> downstream of the outlet structure. These ponds may also promote biological <br /> uptake of pollutants when vegetated. <br /> If problems are identified during inspections, a Work Order will be prepared in <br /> accordance with the following guidelines; <br /> (1) Trees and other vegetation on side slopes will be maintained to provide safe <br /> sight distances for traffic and pedestrians <br /> (2) Sediment and vegetation will be removed around inlets and outlets when flows <br /> are obstructed. <br /> (3) Bank erosion will be corrected when sediment within the pond bottom is greater <br /> than one foot deep. <br /> iv) Private Ponds <br /> Private stormwater ponds are managed by the property owner. <br /> b) Ditches <br /> i) State Ditches <br /> The Minnesota Department of Transportation (MnDOT) is responsible for <br /> maintaining all ditches along State Highways within the City including; <br /> (1) Highway 47 (Saint Francis Boulevard) <br /> (2) Highway 10/ 169 <br />
