• • • 5.2.3 Clearwater Creek RMU Subwatershed Table 11. RMU Specific Actions: Clearwater Creek RMU Actions identified by Issue Category Develop a stormwater runoff volume reduction plan for the Clearwater Creek RMU that emphasizes non - infiltration based BMPs given the heavy hydric soils underlying the area. Integrate Clearwater Creek into district and site planning to preserve the natural amenities of this water course. Address nutrient impairment of Bald Eagle Lake as identified in the TMDL study and in the implementation plan when this effort is completed. Address biological impairment of Clearwater Creek as identified in the TMDL study and implementation plan when these efforts are completed. Restore drained wetlands associated with abandoned ditch 47 to provide wetland mitigation credit for use in a bank and to establish a greenway corridor valuable for open space, water quality, and flood control. Investigate the current and future effects of the pipe and pond drainage system from the urban area just east of 1- 35E and south of Cedar Street for effects on the condition of this wetland complex. The highly susceptible portion of the wetland complex is a hardwood swamp adjacent to the city of Hugo. Target wetland restoration projects in the northern drainage ditch of ACD 55 (a tile system) to alleviate flooding problems and potentially generate mitigation credit. Address the potential flooding concerns in the urban area just east of 135E and south of Cedar Street: there are several ponds that are expected to overtop in a high rainfall event. Coordinate with the RCWD in advance of repairs needed forACD -55 (tile system). This system has been identified as being ineffective at managing future runoff (potential pond flooding problems during high rain events) which should be addressed via the multi - functional .reenwa corridor. GROUNDWATER MANAGEMENT No implementation activities identified. NATURAL RESOURCES Work with RCWD and land developer to implement Clearwater Creek restoration project between 20 Avenue and 35E. Work with RCWD to Conduct Clearwater Creek instream habitat improvement for the biotic impairment TMDL. CON 1. sw No implementation activities identified. 4NS P Complete Subwatershed Management Plan. Monitor the wetland complex to the northwest of Bald Eagle Lake for signs of deterioration from the adjacent urban drainage system. Investigate the localized urban discharges into the wetland complex north of Otter and monitor the wetlands for signs of stress. ON & EDUCATION No implementation activities identified.
