PROJECT GOALS Treat 100% of a 25-year storm event Enhance multi-modal safety and circulation Provide infrastructure for collaborative research and education on campus A Parking Lot Laboratory for Desert Stormwater Mitigation, Research, and Education PROBLEM ADDRESSED The single function 2.48 acre parking Lot, south of the College of Architecture, Planning, and Landscape Architecture, is typical of 269 other surface parking lots on the University of Arizona's campus. It provides minimal shade and no stormwater management.This site's central location is highly used, and is a critical connection on campus serving over 6,000 students. This parking lot will serve as a demonstration site for arid environment research, education and outreach, providing a platform for studying and understanding the role of plants and microbes on remediation of street surface runoff, biogeochemical cycling and permeable pavement performance. (Re)Searching For a Spot will direct future green infrastructure retrofits on campus, and utilize its high visibility on campus to influence sustainable development of the surrounding desert.

Physical signage will be displayed and an electronic display housed in CAPLA East will provide real-time updates of data being collected in research stormwater basins. Dept. of Civil Engineering Painted Crosswalk Research basin area - 8 separate 5'x8' plots Motorcycle parking - same amount as existing Corten steel bridge - allow access across swales Bike racks - provided 6 new bike racks UofA Speech & Hearing Clinics Seating walls - poured on site concrete Permeable pavement -asphalttesting & pavers Eating area - movable tables and chairs Landmark space - public art & educational signage PERSPECTIVE 1 Provide a platform for studying the role of plants and microbes on remediation of street surface runoff, biogeochemical cycling and permeable pavement performance. Bioswale - Native & drought tolerant plants treat stormwater and aid in infiltration and percolation Permeable pathway -ADAcompliant pavers organized to allow water to infiltrate _M&. 1 SECTION A-A Improved spatial and functional relationships between pedestrian, bike, and vehicle circulation, while addressing surface runoff, research, and educational activities Concrete pathway -allows direct views into research plots and presentation gatherings ^ Retrofit existing vegetation - incorporate plants identified for research with existing plants Research Plots - 8 (5'x8') basins - overflow to swale -varying basin treatments (organic, barren soil, & rock/riulch) Rooftop stormwater harvesting - scuppers direct roof runoff into basins Vegetated research swale - check dams & weirs slow water flow - plant groupings used to assess species infiltration performance Non-vegetated research basins -with public viewing access & data collection Traffic calming -visual cues & raised crosswalks, slow traffic for pedestrian safety Educational signage - physical & digital 90 degree parking Computer & Electrical Engineering Creative Center of Photography Infiltration and Percolation to recharge groundwater Water Flow on Site (RE)SEARC^ING FOR A SPOT D7 University of Arizona Nicole Song, Matthew Lutheran, Aaron Johnson, Samantha Swartz, Jack Anderson PERFORMANCE - environmental resilience PROPOSED o EXISTING ------- |
