Mississippi River Community Park Project

Project Background

In 2021-2022, this project has stabilized nearly 1,500 linear feet of eroding riverbank. The eroding riverbank was contributing excess sediment and nutrients to the river, was eliminating wildlife habitat and threatening the integrity of the adjacent trail.  Bare soil and tree roots were clearly visible as a result of the erosion.  

The City of Anoka received two grants totaling more than $700,000 for this project. This project was led by the City of Anoka with assistance from the Anoka Conservation District.


Clear, grade and stabilize nearly 1500' of shoreline within the park.  Re-vegetate the shoreline with native shrubs, plants and trees.  


The streambank will be stabilized by utilizing a combination of regrading, placement of large boulders and rip rap along the toe of the bank, and use of erosion fabric and native vegetation on the slope.


• Moderate to extensive removal of the existing mature trees and vegetation from the river bank. 

• Removal of a short section of the walking trail which will be reconstructed following the completion of the project. 

• Grading of the sections of nearly vertical bank to achieve a stable slope of either 1:3 or 1:2 (vertical to horizontal). 

• Placing of rip-rap at the toe of the slope to help protect against high water flows and ice.  A layer of gravel, small stones, and filter cloth will be placed under the rip-rap to help stabilize the soil. 

• Live cuttings and plant plugs will be planted within rip-rap to provide additional slope stability and give the shoreline a more natural appearance. 

• The slope above the rip rap will be planted with a variety of native grasses, shrubs and trees. • A mixture of large stones and boulders will be placed in the river to create a diversity of flows, aquatic habitat and recreation access points for fishing and viewing the river.

A stabilized, vegetated shoreline helps prevent contaminants and excess nutrients from entering the water through erosion; prevents erosion caused by rain, wind, wave, and ice action; and provides food, shade and cover for fish and wildlife habitat. 

Due to the spring flood waters in 2023, many of the  newly planted trees did not survive the prolonged exposure to high water levels.  Due to the drought that occurred during the remainder of 2023, replanting has been delayed until  2024.
