US Bank Stadium West Plaza Stormwater Solution

Cost

Initial:
100 Thousand USD

Project Status

Operational since 2016

At a Glance

The US Bank Stadium is a multi-purpose stadium and the home of the NFL’s Minnesota Vikings. The plaza located near the Stadium is predominantly paved with some landscaping along the edges and a bike path that bisects the plaza. The west side of the plaza previously consisted of surface parking but stormwater management was required on site to treat the water before it runs into the city stormwater drainage system. A StormTrap treatment system that uses sand media filtration was installed to achieve the City of Minneapolis required removal efficiency of 70% Total Suspended Solids (TSS). The project needed superior load capacity with limited cover and had to accommodate for light pole foundations. The modular design of the system used made it simple to adjust the geometry to meet the various foundational needs. Project builders opted to use this solution instead of a filter type manhole because that would have required additional upstream detention storage where the StormTrap sand filter system would accommodate a more economical and straight-forward maintenance regime.
