Current Status: 

(Updated August 28, 2017) -- The District completed installation of the Powell Road stormwater diversion in 2015, effectively routing over 216 acres of regional stormwater to the future treatment site. Diversion of a pipe near Lake Street will occur in 2017-2018, completed in coordination with Metropolitan Council’s sanitary sewer work, resulting in over 30 additional acres of redirected stormwater. The regional stormwater treatment features will be constructed sometime between 2018 and 2019, after the existing warehouse is demolished and the site redevelopment is planned.  

About this project: 

As part of a larger effort to restore Minnehaha Creek through St. Louis Park and Hopkins, the Minnehaha Creek Watershed District (MCWD) is working to restore more than 1,000 feet of Minnehaha Creek adjacent to an industrial property between Blake Road and the North Cedar Lake Regional Trail. 

The MCWD purchased the 16.9-acre property, currently the site of a cold storage warehouse, in 2011. The District plans to use the property to treat a significant amount of polluted stormwater from surrounding neighborhoods and to restore the channel. After the restoration is complete, most of the land will be sold off for redevelopment to recover purchase costs. Learn more about the acquisition here

Once completed, the project will treat stormwater from 247 acres of urban land that previously drained directly into the creek, most of it untreated. Pipes will redirect that runoff to a stormwater infiltration basin -- a large depression in the ground that collects stormwater and lets it soak into the ground, much like a raingarden

The project will remove and estimated 181 pounds of phosphorus per year from Minnehaha Creek, which will improve water quality and help meet federal pollution standards for the creek and downstream Lake Hiawatha. By adding water to the soil near the creek, the project will also help maintain flow in the creek and prevent it from drying up as often. It will be a cornerstone of the Minnehaha Greenway, a stretch of more than 50 acres of continuous green space constructed or planned for construction along Minnehaha Creek. 

Timing

The project includes two primary stormwater diversions – Powell Road and Lake Street – and construction of the on-site infiltration/filtration facilities. These projects are to be phased over a period of years to coincide with other efforts in the area:

  • Powell Road Stormwater Diversion – Design 2014; Construction 2015
  • Lake Street Stormwater Diversion – Design 2015, Construction 2016-2018 (with Met Council)
  • 325 Blake Road Stormwater Facility – 2018-2019

Funding

This project is financed by the Minnesota Public Facilities Authority including funds from the Clean Water, Land, and Legacy Amendment.
