Our field trip in 2015 explored collaborative urban strategies on the Tijuana-San Diego border under the guidance of architect and urban researcher Teddy Cruz. The on-site two-week workshop, which focused on the transformation of vacant sites into opportunities for spatial inclusion, was led by our codirector Carmen Mendoza and relied on feedback from Teddy Cruz and Fonna Forman of the UC San Diego’s BLUM Cross-Border Initiative together with Sergio Palleroni and Todd Ferry of Portland State University’s Center for Public Interest Design.
