A group of CCA architecture students, led by Landscape Architect David and Rebar art and design studio, shared a meal together at a local taco truck for a class assignment. The research seminar explored San Francisco’s food and wastesheds. The premise was that a seemingly simple, familiar food like the taco truck taco could provide visceral insight into the connections between the systems we were exploring. By thoroughly learning the process of formation and lifecycle what it takes to make a taco, students were better able to propose and design a speculative model of a holistic and sustainable urban future. What resulted was a richly complex network of systems, flows and ecologies that we call the global Tacoshed.
