All Bay Collective Reveals Proposal for San Leandro Bay

Tidal Cities envisions a new way of living with flooding. A dynamic shoreline landscape combines landforms, living levees, and tidal ponds with floating, mixed-use urban neighborhoods. These neighborhoods will be adaptable to future flooding, isolate contaminated soils, and be more resilient to earthquakes. Tidal ponds provide an ideal location to build floating neighborhoods made from prefabricated units craned onto shared decking and supported by pontoons. Floating buildings are less susceptible to liquefaction. Excavating and containing old industrial soils safely sequesters contaminants before they are mobilized in rising groundwater.
