The U.S. Environmental Protection Agency (EPA) today announced the four winners of the Campus RainWorks Challenge, a new design challenge created to inspire the next generation of landscape architects, planners and engineers to develop innovative green infrastructure systems that reduce stormwater pollution and support sustainable communities. The University of Arizona in Tucson, Ariz., was named 2nd place winner for large institutions.
The Campus RainWorks Challenge engages students and faculty members at colleges and universities to apply green infrastructure principles and design, foster interdisciplinary collaboration, and increase the use of green infrastructure on campuses across the nation. Teams of undergraduate and graduate students, working with a faculty advisor, developed innovative green infrastructure designs for a site on their campus showing how managing stormwater at its source can benefit the campus community and the environment.
Stormwater is one of the most widespread challenges to water quality in the nation. Large volumes of stormwater pollute our nation’s streams, rivers and lakes, posing a threat to human health and the environment and contributing to downstream flooding.
The University of Arizona team’s design plan centers on the redevelopment of a 70,000-square-foot parking lot located within a cluster of academic buildings. The design will replace the parking lot with a campus common area featuring two rings of retention basins to infiltrate stormwater runoff, five underground cisterns to harvest runoff and HVAC condensate from the adjacent buildings, and a translucent shade structure with an ephemeral water feature. Water collected in the underground cisterns is used to irrigate the landscape, reducing potable water use from 700,000 to 90,000 gallons/year.
The other challenge winners were the University of Florida, Gainesville (1st prize, large institution), the – Illinois Institute of Technology (1st prize, small institution), and the Missouri University of Science and Technology (2nd prize, small institution). Teams from Kansas State University, Columbia University, California State Polytechnic University, and University of Texas-Arlington were recognized as honorable mentions for their entries.
The challenge received submissions from 218 teams, which were reviewed by more than 30 expert judges from EPA, the American Society of Landscape Architects, the Water Environment Federation, and the American Society of Civil Engineers. Many of the submissions proposed transformative additions to the campus landscape that would reduce stormwater impacts while educating students about the movement of water through the urban environment. The winning teams were selected based on six criteria: analysis and planning; preservation or restoration of natural features; integrated water management; soil and vegetation management; value to campus; and likelihood of implementation.
Green infrastructure helps communities to maintain healthy waters, support sustainable communities, and provide multiple environmental benefits. Green infrastructure captures and filters pollutants by passing stormwater through soils and retaining it on site. Example of effective green infrastructure include green roofs, permeable materials, alternative designs for streets and buildings, trees, rain gardens and rain harvesting systems.
