The Edina Streambank Stabilization Project focused on stabilizing the streambanks of Nine Mile Creek through the City of Edina. The project worked on approximately 3.5 miles of the 5.7 miles of Nine Mile Creek as it flows through the City of Edina. The project resulted in improved stream health, stabilized stream banks, improved habitat, and the protection of property from erosion.
The District used streambank restoration techniques including realigning the creek channel, native plantings, rock vanes, along with other methods. The 3.5 mile project was divided into 15 different reaches (sections) and two phases.
- Totals about 2.2 miles of creek
- Included stream reaches 1-11
- From Lincoln Drive and Londonderry Road in Edina to 5400 of 70th Street West in Edina
- Work started August 2017
- Digging new stream channels (re-meandering)
- Seeding and stabilizing old channels
- Seeding and planting on banks and access areas
Work in phase two occurred in 2018-2019
- Totals about 1.3 miles of creek
- Included stream reaches 12-15
- From the 5300 block of 70th Street West in Edina to the HWY 100 Edina Industrial Boulevard interchange in Edina
- Removal of invasive plants and trees
- Installed rock vanes and other practices in the creek channel
Water Quality Impact
The project reduced streambank erosion resulting in reduced sediment and phosphorus in Nine Mile Creek. It also improved habitat for fish and other aquatic life.
Restoring Nine Mile Creek
With the completion of phases 1 and 2 of the Nine Mile Creek Stabilization and Habitat Restoration Project in Edina, and a previously completed phase in Hopkins in 2010-2011, stabilization and restoration techniques have been completed along more than 4.5 miles of the creek. The projects incorporated both hard structure engineering such as rip-rap, and bio-engineering techniques that include root wads and biologs for stream bank protection. Other techniques included vegetated reinforced soil stabilization (VRSS) for stream bank stabilization, boulder rock vanes for grade control and in-stream flow control, and constructed riffles and pools for in-stream habitat. These projects have reduced nutrient and sediment amounts in the creek, improved stream health, stabilized stream banks, improved habitat, and protected property from erosion.
