San Leandro Bay


Living in the Edge
Our research shows that the key adaptation challenges for the Bay Area are groundwater flooding, vulnerable transportation corridors, and jurisdictional barriers to cooperation. Right now, we’re living on the edge of risk. We believe the solutions to the Bay Area’s social and environmental challenges will come from living in the edge.

At the Oakland Coliseum and San Leandro Bay area, these issues and ideas come together in a unique way and present an unparalleled opportunity to create a new paradigm of how a thriving urban center can support a wide range of economic opportunity and housing alternatives. As the sports teams leave, we see an opportunity to reconnect residents to the resources that surround them. We heard from residents about their disconnection from job centers, grocery stores, and the waterfront. This area has a web of underutilized transit corridors and degraded and threatened riparian corridors. The Coliseum neighborhood has significant groundwater and flood risks. The San Leandro Bay—touching both Alameda and the Oakland Coliseum site—is divided by municipal and infrastructural boundaries.

Our three design concepts can work together at multiple scales to address these issues.

Tidal City
To protect cities from groundwater inundation and seismic risk, we propose floating neighborhoods within artificial, managed lagoons where the groundwater will cause flooding. These tidal lagoons can serve surrounding neighborhoods by holding stormwater while adding new housing units. Clean, excavated fill will build horizontal levees to widen the living edge of the Bay and also raise local roadways to preserve connectivity. The resulting landscape will include “filter parks” to bring nature into the fabric of this district, treating stormwater before it enters the lagoons and the Bay.

Resilient Corridors
This site has several major corridors that need protection from flooding and seismic risks. Some are elevated, like the BART line and station, where access is at risk. Others are low enough that traffic can be interrupted by flooding—and higher groundwater means greater risks of damage in an earthquake from liquefaction. Creek corridors can overflow in rain events and need to be widened, providing park space and wildlife corridors as well as room for rising water. Critical choices can be made to raise or lower highway corridors for the next 100 years to make this area more livable and more resilient.

Resilient Equity Hubs (REHBs)
REHBs are alliances among community advocates, residents, and agencies that can leapfrog jurisdictional boundaries. Oakland has a citywide district called a GHAD that allows property owners to join together and share resources to protect themselves from some coastal hazards, including liquefaction. REHBs can guide transportation investments to support industrial job centers and affordable housing. The goal of REHBs is to bundle governance powers in ways that enable residents to adapt in place, building social and economic resilience by creating shared equity.

We look forward to forming partnerships with the people who call the Oakland Coliseum area and San Leandro Bay area home. We envision a process of co-creation with activist groups and residents that links today’s concerns to a plan for long-term resilience, affordability, decent jobs, and livability.

The All Bay Collective

We are the All Bay Collective (ABC): a diverse group of locally based/globally experienced professionals, academics, students, and policy makers. We have come together to fuse science, design excellence, academic leadership, community outreach, and business innovation to make our Bay Area more responsive to the people who live here and sensitive to the environments we share.

Our partnership signifies a creative synergy that ignites academic discovery and research to professional practice. Together we have an extensive record working closely with cities and communities on climate issues...

Our partnership signifies a creative synergy that ignites academic discovery and research to professional practice. Together we have an extensive record working closely with cities and communities on climate issues in the Bay Area and around the world. A unique piece of our approach is to create teaching, learning, and outreach programs for the fall and spring semesters of 2017/2018 at the UC Berkeley and the California College of the Arts coinciding with the research and the design phases of the Challenge. We believe an important benefit of the Challenge is the ability to deliver a lasting educational legacy of well‐trained students who will become the next generation of planning and design professionals with a strong foundation in resilience.
