Towerside is a rapidly developing area adjacent to the University of Minnesota Twin Cities on a light-rail transit line that connects Minneapolis and St. Paul. In 2013, Barr worked with four private developers to design and construct the first phase of the Mississippi Watershed Management Organization's proposed district stormwater management system to serve multi-family residential developments valued at over $250 million. Our design includes stormwater conveyance, large biofiltration basins (rain gardens) to filter out pollutants and provide a public gathering space, an underground concrete tank to store treated stormwater, and a pumping system to deliver treated water to the developments for irrigation.
The first of its kind in Minneapolis or St. Paul, the district system is the result of a voluntary agreement between developers owning adjacent properties to manage runoff jointly. Taking a communal approach reduces costs for the landowners while incorporating more effective and environmentally friendly stormwater treatment methods. The system went online in 2016 and is treating water for the first development. When fully operational, it will treat an estimated annual average of 4.5 million gallons of stormwater for reuse. We are now helping plan the expansion of Towerside and manage stormwater for an additional 20 acres once it is developed.
