TCF Bank Stadium – South Plaza

The University of Minnesota was developing a new football stadium on the University’s East-Bank campus in Minneapolis. Mortenson Construction was the general contractor that worked with various designers, engineers, University officials, the City of Minneapolis and our Solution Blue team members to successfully execute the planning, financing, design and construction of this state-of-the-art, LEED® certified athletic facility.

Challenges

Located within a highly-developed urban setting with minimal space available for stormwater management features.
Difficult to achieve stormwater management (quality & quantity) objectives due to lack of available green space.
University needed to establish an economically and environmentally viable solution to manage stormwater on-site.

Solution and Results

Solution Blue team members designed and implemented an innovative stormwater management system within the plaza along University Avenue. Our team designed, engineered and managed the installation of this cutting-edge stormwater system.

Employed an all-in-one system that provides superior drainage, storage, water re-use and complete stormwater management.
0.50-acre green space accommodates 3.75-acre watershed and efficiently manages the 5-year rainfall event (3.5” in 24 hours).
0.50-acre green space provides 120,000-gallon storage capacity (within soil profile and temporary storage above turfgrass).
Incorporated mesh materials in soil profile so turfgrass can effectively support heavy broadcasting and emergency vehicles.
System’s pollutant removal rates: 90% TSS (Total Suspended Solids), 80% Phosphorus, 60% Nitrates.
Stadium became the first ever LEED® certified collegiate football stadium in the U.S., achieving LEED^® Silver Certification.
