PUBLIC SEDIMENT is a multidisciplinary design team that views sediment as a core building block of resilience in San Francisco Bay. UNLOCK ALAMEDA CREEK is a proposal to address the challenge of sediment scarcity along the vulnerable urban edges of Fremont, Union City, and Newark. The baylands require sediment to keep pace with sea level rise, yet sediment is trapped upstream in dams and flood control channels. To bring sediment to the baylands, we look upstream to Alameda Creek, the largest local tributary, 660 square mile, that feeds the Bay. Our proposal aims to redesign this waterbody to create functional systems that sustainably transport sediment, engage people, and provide habitat for anadromous fish.  Public Sediment includes team lead Scape, and collaborators TS studio, Arcadis, the Dredge Research Collaborative, UC Davis and Buoyant Ecologies Lab.
