University of Arizona Team Members: Jon Choi, Jenny Moscato, Cody White Sarnaritha Swartz, Jack Anderson SOCIO-HYDROLOGY A frame for an integrated green infrastructure campus master plan practices are compounded by an ever growing student body population and climate change. The following 15-acre master plan proposal introduces integrated green infrastructure (GI) practices to better utilize water as a resource on the University of Arizona campus while providing a dynamic space for cross-disciplinary collaboration while engaging a broader community.

Student Union Memorial Center Bioswale network connects beyond site and accounts for overflow Curb cuts alleviate flooding on street and provide supplemental irrigation Native plantings reduce urban heat island effect while intercepting rain Perforated bridge allows water to pass through and under into basins SCALABLE CAMPUS STRATEGIES Typologies of smaller scalable strategies specific to the 2nd St. corridor proposal seek to demonstrate GI (solutions that can be implemented 011 abroader scale within the neighboring and upstream campus landscape.

The 2nd Street corridor is a major vehicular and pedestrian thoroughfare running along the historic northern border of the University of Arizona. The 2nd Street DESIGN PERFORMANCE AND IMPACT corridor is the downstream confluence of 18 sub-basins within one of the 5 major watersheds on the University of Arizona campus. Runoff from contributing sub-basins leads to over 4.3 acre-feet of water running across the site. This creates dangerous conditions for pedestrians, cyclists and drivers.
