<br />All proposed management programs establishing a classification system for the management of water <br />bodies shall be consistent with water quality Standards for Waters of the State, per Minnesota Rules <br />Chapter 7050. <br /> <br />The following are management practices recommended by the WMO and implemented by the <br />municipalities. . <br /> <br />Maintenance Guidelines <br />Each practice shown in bold print includes a description of the minimum standard required to achieve <br />the guideline: <br /> <br />Biannual (twice per year, usually fall and spring) Inspection of all wetland areas and ditches <br />Brief walking inspection to record sediment buildup, skimmer and structure conditions, litter, <br />vegetation, and visual water quality in the spring and fall. <br /> <br />Street Sweeping <br />Following snowmelt in the spring and in fall after leaves have fallen. <br /> <br />Catch Basin Cleaning <br />Frequency necessary to prevent encroachment of sediment and debris above flow line of pipe. <br /> <br />Inspection of Direct Storm Sewer Discharge Points to Protected Wetlands or Water Bodies <br />Inspection on biannual basis and following large storm events to determine if discharge point is free <br />from sediment and to observe the condition of any treatment facility if applicable. <br /> <br />Removal of Sediment <br />Based on biannual inspections, -sediment shall be removed from areas where the sediment impedes <br />the flow path, from areas not designated for sediment removal, or where sediment buildup has <br />eliminated necessary storage volume. <br /> <br />Structure and Skimmer Maintenance <br />Based on biannual inspections and following heavy rains, maintenance needs should be developed. <br /> <br />Litter Control <br />Biannual wetland inspections and collection. Seasonal public education efforts. <br /> <br />Harvesting of Vegetation <br />In areas specially developed and maintained to control and reduce nutrients, vegetation should be <br />harvested in the late summer of each year. Stormwater should then be diverted from the treatment <br />area until vegetation can be reestablished. <br /> <br />Water Management Plan <br />P:\Mpls\23 MN\02\2302047\WorkFiles\3rd Gen WMP\LRRWMO_3rd Gen WMP_July 2009_Draft.doc <br /> <br />89 <br />
