Advanced street sweeping studies are being completed by ACD staff to identify locations where strategically increasing the frequency of sweeping would result in the greatest water quality benefits to the Rum and Mississippi rivers. The highest priority areas for this effort are typically those with limited existing stormwater treatment and/or high roadside tree canopy cover, both of which contribute to increased pollutant loads in stormwater. 

The photo above shows a street sweeping prioritization map produced through the enhanced street sweeping analysis for the City of St. Francis; green indicates the highest priority streets, and red indicates the lowest, for achieving water quality improvements to the Rum River. These analyses are also being completed for portions of Ramsey, Andover, and Anoka. Detailed reports and recommendations will be provided to these cities upon the completion of these studies.

Staff from ACD, U.S. Fish and Wildlife Service, and Minnesota Native Landscapes (the construction contractor) are shown above during the construction of a wetland restoration at Martin's Meadows in the City of Andover. Project collaborators not pictured above include The Nature Conservancy and the City of Andover. Several similar collaborative wetland restoration efforts are planned for both public and private properties soon! Contact ACD if you're interested in wetland restoration on your property.

Construction has concluded for nine lakeshore stabilization projects on the Sunrise Chain of Lakes: four on Martin Lake, three on Linwood Lake, and two on Coon Lake. Project locations were selected in 2024 based on the property's need for restoration and the anticipated water-quality benefits the project would deliver. Detailed designs were compiled, and three primary bioengineering approaches were applied. 

Funding for these projects was through a Clean Water Fund grant, the Sunrise River Watershed Management Organization, Soil and Water Conservation District (SWCD) Aid, and landowner match.

Several recently installed lakeshore projects feature a new combination of materials to protect from erosion while restoring the native plant community. Our newest approach incorporates the use of rock, coconut fiber coir logs, and a diverse native plant buffer to stabilize shorelines experiencing moderate erosion. 

 Rock was placed to the elevation at which vegetation struggled to grow and erosion regularly occurred. This elevation is different for each lake and is based on water levels, wind fetch and wave models. The goal was to choose a rock type that would create a more natural look, while still providing protection and function, while preventing undercutting and collapsing of the sandy soils above.

16" coconut fiber coir logs were installed in the zone where water level fluctuations regularly occurred, but vegetation was capable of growing. This log will protect the new plants from wave and ice action while they become established. Eventually, the log will decompose. The coir log was anchored with a new technique using sisal rope and earth anchors for a stronger hold and improved aesthetics.

A buffer of native vegetation was planted behind the coir log. Their deep and interconnected roots will serve as the long-term stability for this shoreline. 

This approach also allows for installation with smaller machinery or by hand, facilitating application to shorelines with limited access or a need to work around existing natural shoreline features.

Each year, ACD staff revisit a variety of previously installed projects to ensure that they are holding up throughout their expected lifespan. For the project owners, this is an opportunity to reconnect with technical experts and ask questions. For project managers, this improves our understanding of which materials and approaches result in the greatest success over time. For the projects themselves, this helps address issues before they become unmanageable, ensuring the natural resource benefits provided continue for years to come.
