• • Clearwater Creek is currently under investigation for a biological impairment and will likely be funded in 2008 for a biological TMDL. These efforts will identify additional subwatershed areas to investigate for source reduction of nutrient loading to both the creek and lake. • The wetland complex north of Otter Lake contains rare and high quality vegetation, including a cranberry bog. They are very sensitive to changes in water chemistry from urban runoff, and formed under groundwater discharge conditions. Localized urban discharges that started occurring in the last 15 years should be investigated and the wetlands monitored for signs of stress. Source reduction measures should be employed to infiltrate urban discharge and remove it from the wetlands. • The northern drainage ditch (ACD 55, a tile system) is under consideration for repair needs. There is an enormous amount a fully drained wetland in the area. Given the potential pond flooding problems during high rain events (see yellow dots), consideration needs to be given to target wetland restoration projects. This will alleviate the flooding problem and could potentially generate mitigation credit. In addition, it can be anticipated that under the future urban land planned for this area (see Figure 10 -7), significant attention needs to be given to runoff volume control. Since heavy hydric soils underlay the area, noninfiltration -based BMPs will need to be incorporated. This planning is important since the catchments will ultimately affect Clearwater Creek and the downstream impaired water, Peltier Lake. Planning District 4 • Overall Recommendations • The City acquired 60+ acres at the southeast corner of Birch Street and Centerville Road with the intent to creating a major community athletic complex. A master plan was created for the complex, including fields for soccer, baseball, and softball, as well as playground and other facilities. The City should continue to pursue the possibility of constructing the athletic complex. • • Integrate Clearwater Creek into district and site planning to preserve the natural amenities of this water course. • A gateways should be considered at the intersection of Centerville Road and County Road 3 (Ash Street). • Work with White Bear Township to create Joint Powers Agreements for municipal utility service. • Pursue a full interchange at I -35E and County Road J (Ash Street). • Work with Anoka County to prepare an access management plan for Birch Street (CSAH 34) • Work with Anoka County and Ramsey County to ensure appropriate access management on County Road J (Ash Street). • Examine the possibilities for realigning County Road J (Ash Street) to eliminate the two right angle turns and minimize the curves that replace them. • Examine the possibility of extending Molitor Drive east to connect to 20th Avenue. 10 -23
