City of Franklin Ravine Repair Project

We invite you to comment on the draft 401 Water Quality Certification for City of Franklin Ravine Repair Project in Renville County.

The City of Franklin proposes impacts to 2,040 linear feet of unnamed tributaries to the Minnesota River, and 105 linear feet of the Minnesota River. The impacts include grading and installing a step pool system to reduce erosion along a ravine that currently carries stormwater from the city’s streets. In addition to the step pools, there will be stabilization at the outlet of the stormwater outfall, and a new, larger 42” culvert installed under County Rd 5. There will be two additional spurs of the tributaries that will be enclosed in pipes that currently carry runoff from agricultural fields.

No mitigation is required for this project.

3A 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.
