Mississippi River Community Park Riverbank Stabilization
Eroding river banks contribute to the Mississippi River's TSS & turbidity impairments through direct
loading of sediment and nutrients that degrade overall water quality as well as aquatic & nearshore habitat. Inventories assessing bank conditions were completed along 13.3 miles of the Mississippi River from the Coon Rapids Dam to Anoka County's western edge. This project will stabilize a site prioritized with the third most sediment loss into the river - 1,469 linear feet within the City of Anoka's Mississippi River Community Park.
The project will combine bioengineering, aquatic habitat, an armored toe and recreational access. Technique will vary amongst sections of riverbank that have differing slope and erosion severity. Native vegetation will be used throughout.
The project will reduce pollutants by 529 tons of sediment and 847 pounds of phosphorus annually. Other benefits include aquatic life diversity and abundance, and improved drinking water quality. This project is immediately upstream of Twin Cities drinking water intakes.
This project will also showcase river stewardship and enhance public recreation. Mississippi River Community Park and adjacent city-owned King's Island include 1.7 miles of Mississippi River trail, 0.78 miles of riverfront, 0.91 miles of oxbow channel, pedestrian access to the island, sporting fields, public duck & deer hunting, and fishing dock. This project will make over ? mile of unsafe riverbank more accessible, stable & fishable for users. By naturalizing the riparian zone this project complements the recently updated Mississippi River Corridor Critical Area (MRCCA) rules.
The project cost of $816,726 will be paid by $163,400 from the City of Anoka and this $653,326 Clean Water Fund request. The city owns the property & will accept maintenance responsibilities throughout the life of the project.

(b) $16,000,000 the first year and $16,000,000 the second year are for grants to local government units to protect and restore surface water and drinking water; to keep water on the land; to protect, enhance, and restore water quality in lakes, rivers, and streams; and to protect groundwater and drinking water, including feedlot water quality and subsurface sewage treatment system projects and stream bank, stream channel, shoreline restoration, and ravine stabilization projects. The projects must use practices demonstrated to be effective, be of long-lasting public benefit, include a match, and be consistent with total maximum daily load (TMDL) implementation plans, watershed restoration and protection strategies (WRAPS), or local water management plans or their equivalents. A portion of this money may be used to seek administrative efficiencies through shared resources by multiple local governmental units. Up to 20 percent of this appropriation is available for land-treatment projects and practices that benefit drinking water.
This project will stabilize 1,469 linear feet of severely eroding priority riverbank in the City of Anoka's Mississippi River Community Park, achieving pollutant reductions of 529 tons of sediment & 847 pounds of phosphorus annually.
Grant funds funded the project that stablized 1400 linear feet of streambank, resulting in a reduction of 847 lbs/yr of phosphorus and 529 tons/year of sediment to the Mississippi River.
