SCAPE has designed a Public Sediment plan for Alameda Creek in California United States with a focus on allowing sediment to flow from streams into the marshes and mudflats of tidal ecosystems.
River ecosystem refers to the ecosystem of river water body, which is a kind of water ecosystem. It is the link between land and ocean, and plays an important role in the material cycle of biosphere .The Bay Area’s tidal ecosystems—its marshes and mudflats—are at risk of subsidence and drowning with low sediment supply and sea level rise. Public Sediment for Alameda Creek proposes that sea level rise adaptation must extend upstream, redesigning sediment flows to sustain tidal ecosystems and protect vulnerable communities.
Reason to Be Selected
The project proposes to reintroduce sustainable sediment flows, ecological connectivity, and public access back to the creek to address future climate change threats. The project won the 2019 ASLA analysis and planning Honor Award.
Resilient by design
Public Sediment for Alameda Creek is a plan created with extensive input from community stakeholders for the Resilient by Design initiative to regulate our relationship with sediment and water resource for sea level rise adaptation, combined a network of community spaces for people and habitat of original fish in rivers.
The proposal represents a paradigm shift in how we plan for climate change.Based on scientific research on the subsidence and loss of tidal wetland ecosystems caused by sea level rise and insufficient supply of sediments, the planning team studied the supply and resilience of sediments in Alameda rivers and bays, and proposed four types of construction Public passages, including silt chambers, flood storage rooms, platform walkways, and all-season bridges, can not only promote the connection and interaction between communities, and ensure the safety of river use, and coordinate the edge of the bay area by connecting rivers and land.
In order to improve the resource value of the river and obtain the participation and recognition from the surrounding communities, the project team held several activities in the riparian zone, and recorded the public's awareness, memory, and intention to use the current status of the riparian through Creek Atlas.
Public Sediment for Alameda Creek introduce sustainable sediment runoff, establish ecological connectivity, and reshape the public path to the stream, to avoid the lack of sediment caused by upstream dams and channelization projects that will cause slow but devastating large-scale losses, and raise awareness and develop implementable solutions for sea level rise adaptation in the Bay Area.
