Coon Creek Watershed District (Coon Creek bank stabilization) - 401 Water Quality Certification
We invite you to comment on the draft 401 Water Quality Certification for the Coon Creek bank stabilization in Anoka County.
The Coon Creek Watershed District proposes to stabilize 4,250 linear feet of Coon Creek’s banks just upstream of the creek’s confluence with the Mississippi River.
The project will include 2,265 non-contiguous linear feet of bioengineering and grading to install log toes, root wads, and seed slopes. In areas of particularly severe erosion or with springs and other features that make bioengineering challenging, the watershed district will install 1,990 total linear feet of rip rap.
In addition to the bank stabilization, the watershed district proposes to excavate two existing oxbows to a 2-foot depth to provide overflow and habitat. The dredging will remove a total of 11,200 cubic feet of material. No mitigation is proposed for this project.
A 401 Water Quality Certification is required when an individual, business, or property owner proposes construction-related activities near a navigable lake, river, stream, or adjacent wetland. The MPCA reviews projects to ensure they will not violate Minnesota's more protective water quality standards. The 401 certification becomes an enforceable component of the associated federal license or permits issued under the Clean Water Act.
