SOUTH BAY SPONGE
NATURE, TECHNOLOGY AND RESILIENCY IN THE SOUTH BAY
The South Bay Sponge is a design framework for adaptation - for adapting our shoreline and infrastructure and for advancing our methods of planning, design and cooperation to achieve new and resilient forms of settlement on the Bay.
The Bay is so many things to so many different people – it is a place of beauty, serenity, ecology, recreation, economy and identity, to name just a few. The Field Operations Team worked closely with the communities in the South Bay and Silicon Valley to shape a vibrant and living framework for adaptation in the face of climate change and sea level rise, envisioning a future where nature and technology work together to improve the resiliency of our cities and towns, our social fabric and our collective health and well-being.
The “Sponge” is a concept for using nature and natural systems as a primary tool for climate adaptation and resiliency in the South Bay, inspired by both the historic function of the region’s inter-tidal marshlands as flood protection, as well as by the remarkable efforts to restore the South Bay Salt Ponds. The potential of a large-scale assemblage of remnant marshlands, newly restored salt ponds and newly constructed wetlands as the core component of a regional flood protection strategy is at once radically innovative, but also resonant with the South Bay landscape today. In addition to addressing climate adaptation, the South Bay Sponge can give the landscapes of the South Bay a powerful and legible identity.
South Bay Sponge
The South Bay Sponge is a framework for resilience that thoughtfully imagines new possibilities for climate adaptation in the South Bay that can grow in scale, incentivize investment, build public support and excitement, facilitate coordination across jurisdictions, and contribute to the larger effort to increase resilience in the Bay Area.
The ‘Sponge’ is green infrastructure on a large-scale: new absorptive landscapes for collecting, filtering and dispersing flood waters during storm events. The Sponges are also diverse eco-tones, designed with topographic variation to support a range of ecological conditions from ponds, to marshlands, to transitional and seasonal wetlands, to floodable parks and green spaces at higher elevations alongside new and existing neighborhoods and development.
The South Bay Sponge project covers more than 20 miles of shoreline, stretching from Bedwell Park in Menlo Park to the San Tomas De Aquino Creek in Santa Clara. The South Bay Sponge project is a multi-jurisdictional vision: the project encompasses two counties (San Mateo, Santa Clara), one water district (Santa Clara Valley Water District), six cities (Menlo Park, East Palo Alto, Palo Alto, Mountain View, Sunnyvale, Santa Clara), and at least five federal agencies (National Marine Fisheries Service, U.S. Army Corps of Engineers, U.S. Fish & Wildlife Service, U.S. Natural Resources Conservation, NASA).
The South Bay and Silicon Valley include some of the lowest-lying and most vulnerable communities to sea level rise in the Bay Area, and at the same time are growing rapidly without big plans for increasing housing, transit connectivity, or cooperation between jurisdictions. Any effort for resiliency in the South Bay must consider these vulnerabilities.
And yet, Silicon Valley is a global center of innovation. Any innovations in the global effort to address climate change are poised to happen here!
The South Bay Sponge big, ambitious, complex and seemingly impossible to implement. The level of cooperation required across jurisdictions is unprecedented. However, the cooperation involved is necessary. Without a cohesive, multi-jurisdictional solution - massive financial, infrastructural, ecological and human losses will occur and reoccur - and the most vulnerable of South Bay communities, East Palo Alto, will be left behind.
The South Bay Sponge project proposes new framework for cooperation and coordination across jurisdictions in the South Bay. Each municipality would enter a collaborative agreement to define how the region messages, deliberates, prioritizes, acquires funds and implements multi-benefit resiliency projects. The framework may take the form of a Special District - The South Bay Multi-Benefit Resiliency District - whereby a host of funding mechanisms become feasible. This cross-jurisdictional cooperation could all start with something as simple as an MOU between jurisdictions. While the Santa Clara Valley Water District and San Mateo County Flood District already have mechanisms in place to fund components of the South Bay Sponge, it is clear that significant additional funds are required for continuous protection across the region and significant coordination is required to make it all happen.
In this way, the South Bay Sponge becomes the idea, the framework and the motivation for this new form of cooperative planning for a more resilient South Bay.
There are a variety of ways in which the South Bay Sponge project might continue in the near-term. We have received enormous support from all stakeholders involved, and have had a remarkably successful public engagement process that is a model for messaging, educating and inspiring a broader public. In any scenario, however, specific funding sources would be needed to support further work, whether for continuing the public engagement and education efforts; for continuing project planning and feasibility assessments; for the preparation of a more detailed and implementable pilot project; or, to identify further sources of capital funding.
The Field Operations Team is a collaboration led by James Corner Field Operations with Acterra, Andrea Baker Consulting, H.T. Harvey & Associates, Moffatt & Nichol, Magnusson Klemencic Associates, The San Francisco Bay National Estuarine Research Reserve, The Bay Institute, James Lima Planning and Design, SeArc-ECOncrete, Adventure Pictures, and Playhou.se Animation. Our approach to outreach and engagement in the South Bay is ‘Come one, come all!” We set out to listen to, learn from, and collaborate with any and all agencies working on projects related to sea-level rise or to bayfront planning in general, as well as any and all residents that we could welcome into our process. South Bay Sponge active stakeholders include: Acterra, California Coastal Conservancy, Citizens Committee To Complete The Refuge, City of East Palo Alto, City of Palo Alto, City of Sunnyvale, East Palo Alto Residents, East Palo Alto Residents, EPA Phoenix Academy, Google, Joint Venture Silicon Valley, Mountain View Residents, Mid-Pen Regional Open Space District, Metropolitan Transportation Commission (MTC), NASA, Northern California Grantmakers, Palo Alto Residents, San Francisquito Creek Joint Powers Authority, San Mateo County Office of Sustainability, Santa Clara County Office Of Sustainability, Santa Clara Valley Water District, SFEI, South Bay Salt Pond Restoration Project, Stanford Univ.
