In June 2014, a record storm caused 10,000 square feet of the Mississippi River bluff to fail, burying West River Parkway and exposing hospital infrastructure. The Minneapolis Park and Recreation Board hired Barr to monitor slope and infrastructure stability and then design and observe construction of repairs. Work was complicated by the extremely steep slope; limited access; seepage; weak soils; stability concerns; and an active hospital facility with loading, noise, and emissions restrictions. Barr integrated soil nails and five retaining walls to design a unified stabilization system and specified low-vibration installation techniques to curtail the potential of additional slides. Completed under budget, the project helped ensure public safety without interrupting hospital operations. The parkway reopened for commuters and cyclists on September 16, 2016, just in time for the Twin Cities Marathon.
