High school students, community groups and Lake Superior State University will use landscaping this summer to reduce pollution flowing into the St. Marys River.
The project recently received $250,000 from the United States Forest Service as part of the Great Lakes Restoration Initiative, a program that protects Great Lakes drinking water and habitat.
Stormwater carries things like trash and bacteria from the city, through the drainage systems and into the river, according to the Environmental Protection Agency. Landscaping, also known as green infrastructure in this context, reduces or treats stormwater runoff on its way to a river or lake.
The university’s project will use soil and native plants to collect and filter out pollutants before runoff reaches the river, said Ashley Moerke, the director of the Lake Superior State University Center for Freshwater Resources and Education.
“Part of us being an old city with a lot of former industrial development is that we no longer have those natural features,” she said. “It is a really simple mechanism. It’s creating depression areas and planting (them) with native plants that absorb (stormwater). It’s not this complicated idea, but it’s something that we’ve really moved away from.”
The landscaping will surround the proposed Richard and Theresa Barch Center for Freshwater Research and Education building. Once built, the center will house research labs, teaching labs and a Great Lakes visitor center.
The university is building the center on a former industrial site contaminated with pollutants. The land previously held a chemical factory. The plan always included green infrastructure, but cleaning the site was more expensive than the university had budgeted. This prevented Lake Superior State from including the landscaping it wanted, Moerke said.
“When part of the [factory] was removed, much of the material was buried.” Moerke said. “So, when we started to put the foundation of our building in, we found whole railroad tracks, these huge cement abutments and a tremendous amount of debris. It ended up increasing the cost of our project like another million and a half.”
One of the Forest Service’s priorities this year was “advancing green infrastructure to reduce pollutant runoff from degraded sites,” said Sheela Johnson, the Great Lakes Restoration Initiative grant program manager for the Forest Service.
The agency was looking for a project that would turn a liability with poor quality soil into a natural landscape where vegetation can capture water and soil will allow it to flow more naturally, like it would in a forest, Johnson said.
The St. Marys River project met many of the Forest Service’s requirements, including involving students and community members, educating the public, reducing pollutant runoff and building on a former brownfield site, Johnson said.
Moerke said she hopes the project will inspire Sault Ste. Marie residents to expand green infrastructure along the river.
“This will be the first project in our region to use this type of approach,” she said. “So, we’re hoping that’s going to introduce the community to ways to be more environmentally friendly as we develop.”
High school and college students, youth groups and the Chippewa Luce Mackinac Conservation District will help the university begin planting in late August and continue into September, Moerke said.
The Forest Service will begin accepting grant applications for the Great Lakes Restoration Initiative again in spring of 2021.
I love your plan to increase green infrastructure along the river. That is exactly what is needed. I do have one concern and that is the proposed ferrochrome smelter to be constructed in Sault Ste. Marie Ontario. The construction on such a toxic chemical producing plant along with the Algoma Steel Plant creates grave concern for both sides of the Saint Marys River. Please let us know your thoughts regarding the ferrochrome smelter on the river.
