CAMPUS RAINWORK CHALLENGE
Campus Rainworks Challenge is a team project for designing green infrastructure on the watershed of the East Bank campus of the University of Minnesota to engage the big idea of the water bucket onsite, foster a dialogue about the need for innovative stormwater management techniques, and showcase creative design solutions.
