Minnesota Stormwater Seminar Series

Please join us in person or online for two seminars in May: Friday, May 2 and Thursday, May 15. The Minnesota Stormwater Seminar Series is a monthly experience featuring national, state, and local experts on stormwater and green infrastructure.

*May 2 Seminar: Turning Tight Spaces into Big Solutions: Testing a high-volume stormwater filter at Rosland Park*

*Date and Time*: Friday, May 2, 2025, 11a-1p CDT

*Presenters and Panelists: *


* Andy McCabe, Environmental Engineer at Barr Engineering
* Erica Sniegowski, Administrator for the Nine Mile Creek Watershed District

*Additional Panelists:*


* Kyle Axtell, Watershed Project Manager, South Washington Watershed District (SWWD)
* Nancy Stowe, Projects and Outreach Director, Mississippi Watershed Management Organization (MWMO)

*Abstract: *The Nine Mile Creek Watershed District (NMCWD) and the City of Edina joined forces to create a groundbreaking stormwater filtration system in Rosland Park designed by Barr Engineering, designed to reduce phosphorus loading into Lake Cornelia in a tight, urban setting. This innovative active BMP includes an anthracite prefilter followed by three different parallel media filters, specifically engineered to remove dissolved phosphorus in a small but powerful system.

What makes this project stand out? It’s the challenge of fitting a high-performance treatment system into a limited urban space while still managing large volumes of stormwater. This could provide game-changing solutions to those struggling to meet water quality goals in growing urban environments. But the real story lies in the research. Led by Barr Engineering, the team rigorously tested the performance of all three filters, measuring their effectiveness in reducing phosphorus loading to the lake. This research will provide valuable insights into the future of stormwater management in Minnesota, showing the potential to use smaller, more efficient systems that could have a big impact on water quality, targeting removal of nutrients that are unsettleable by traditional means.

*May 15 Seminar: Using Winter Chloride Management to Reduce Impacts of Winter Maintenance Operations*

*Date and Time*: Thursday, May 15, 2025, 10a-12p CDT

*Speakers:*


* Keynote: Laura Fay, a Senior Research Scientist and Program Manager at the Western Transportation Institute (WTI) at Montana State University (MSU),
* Panelist: Allison Madison WI Salt Wise
* Panelists: TBD

*Abstract: *Chloride-based deicers are used to maintain safe and passable roadways and pedestrian facilities, as well as to treat parking lots. Winter chloride management encompasses so much of winter maintenance operations, from storage, capacity, application methods and rates, plowing routes and timing, training, the triple bottom line (economic, social, and environmental considerations), data collection, and operations assessment. This talk will present winter chloride management strategies as a changing practice, incorporating new technologies and products, and the intersection of these changes and improvements leading to reductions in operational impacts.
