How Minnesota Developed Its First Sustainable Sports Stadium

City residents and visitors to Saint Paul are watching with anticipation as Minnesota’s first purpose-built stadium for professional soccer rises from a former retail and industrial site at the corner of Snelling and University Avenues. Allianz Field and its surrounding development is one of the larger redevelopment projects in the city’s history.

Prior to stadium construction, all stormwater runoff from the site flowed to the Mississippi River without treatment. The site’s lack of permeable surfaces has contributed to river’s sediment and nutrient pollution.

To minimize the stadium’s and entire site’s environmental impact, the City, CRWD, MN United FC, and retail owner, RK Midway are designing a shared, stacked green infrastructure (SSGI) system.  This green system treats stormwater from multiple parcels with shared practices that utilize landscape features or natural processes for environmental benefit.

The green infrastructure improvements on the stadium property include:

These stormwater improvements will help protect water quality, reduce use of potable water supplies and enhance the tree canopy to improve air quality.

The stadium is scheduled to open in spring 2019. Other key milestones for the project include:
