Sixteen UO juniors wielding tape measures and sketchbooks trudge through a grassy field with the property owner, taking in and jotting down all they survey. That 3-acre site will serve as a blank canvas for the students in assistant professor Christina Bollo’s architecture studio as they work to solve pressing housing problems facing the city. Bollo’s studio is one course of many in the UO’s Sustainable City Year Program, an idea spawned at the College of Design in 2009.
