The Oakland Coliseum attracts visitors, igniting economic growth in the city, but ignores those who actually live next door. Residents struggle with the lack of low-skill jobs, and the same transit system that brings visitors to the Coliseum has created barriers for pedestrians. As the sports teams leave and sea levels rise—as well as new development is proposed—this kind of segregation could become even more severe. Rather, how could we reunite the neighborhood? Instead of defending or rebuilding the San Leandro waterfront, Lifted Commons accommodates an ever-changing shoreline with a raised public platform. The platform is both thin (for circulation, biking, bird-watching, and animal migration) and thick (to host schools, worker training facilities, housing and commercial space), and it can switch from one to the other as needed. Volumetric cones link spaces vertically, filter water, and contain a new, suspended landscape. Hydrologically, this system can discharge water to the Bay and connect to a series of smaller water ponds throughout the neighborhood. Economically, the platform can accommodate expanding small businesses or house residents displaced during a temporary flood. Socially and politically, this can activate a new kind of collective space: in our graphic narratives, we imagine two scenarios of ownership—public and private—each with different degrees of risk-sharing, cost of living, and potential for change.
