Allianz Field

Location: 400 Snelling Avenue North, St. Paul, MN 55104

Nominated by: Minnesota United Football Club

Allianz Field is a 250-million-dollar soccer-specific stadium, and home to the Minnesota United FC of Major League Soccer. The 19,400 seat stadium has transit connections provided by the Metro Green Line and Snelling Avenue Bus Rapid Transit. The stadium was constructed on a 21-acre brownfield site. Formerly, the property was a street car and bus transit facility that included historic manufacturing and maintenance activities dating back over 100 years.

Remediation included the removal of asbestos-containing materials, and lead and PCE impacted soil, as well as other contamination. A sub-slab soil vapor mitigation system was installed beneath enclosed areas of the stadium. Also, an innovative barrier-wall system was engineered to protect the structure from contaminated perched groundwater.

The project partners also designed and constructed an innovative shared, stacked green infrastructure stormwater system servicing the entire “super block” around the stadium. As part of this system, reclaimed water from rooftop runoff is used to irrigate the three-quarter-acre park north of the stadium, and other green spaces. After full development of the parcels adjacent to the stadium, the system will result in the conservation of upwards of 2.8 million gallons of water per year, while also helping to achieve greater density on the site. This type of shared system has not been implemented at this scale before, and is expected to serve as a model for future developments. It also showcases the sustainability benefits that can be achieved through effective public-private collaboration.

The project created 110-full time and 480-part time jobs, within the stadium. In addition to the public transport access, Allianz Field also utilizes a dedicated area for app-based ride-sharing, and has 400 bike parking spots. Finally, the development is expected be a catalyst of revitalization in the neighborhood, as well as for the growing soccer fan base across Minnesota, bringing together diverse people to enjoy the “World’s Game”.
