This project will identify and prioritize opportunities to implement a multipurpose drainage management plan that will provide adequate drainage capacity, reduce peak flows and flooding and reduce erosion and sediment loading, improving water quality to the West Branch Rum River.
This project will install nearly 800 linear feet of restored lakeshore with an emphasis on bioengineering techniques, native plants and locating buffers/swales at points of concentrated overland flow into Green Lake. By targeting properties that are eroding and/or with concentrated overland flow to the lake we will reduce suspended solids discharge by 16,697 lbs/yr and phosphorus by 1.3 lbs/yr.
This project is located in an area in the City of Isanti that developed before modern-day stormwater treatment requirements. It will result in the installation of a new stormwater pond in a historic core neighborhood. The urbanized drainage area presently has no other stormwater treatment, except for street sweeping. The new stormwater pond will reduce discharges from a 55 acre site draining to the State Scenic and Recreational Rum River by 12 pounds/yr for phosphorus and approximately 3 tons/yr of sediment.
