Rain gardens in Little Falls may help protect Mississippi River waters
Being a river town can have its challenges, one being how to pollute that river as little as possible.
The Little Falls City Council heard from Shawn Tracy with WSB, an engineering firm out of St. Cloud, about a few steps the city can take now, that may save it some money and effort not far down the road. He said right now, while the city has an obligation to reduce pollutants, it does not have a “legal” obligation to so. However, when Little Falls is put on the “total maximum daily load” list or TMDL, there will be allocations as to how many pollutants can come from the city.
“Anything you do between now and that point, you get credit down the road,” Tracy said.
Grant funding that is available now, should the proper plans be in place, won’t be available when the TMDL goes into effect, he said.
In addition to underground filtration piping of stormwater, an expensive but low maintenance project, Tracy spoke of boulevard rain gardens that also act as filtration systems.
