Honourable Mention, San Francisco Bay Conservation and Development Corporation Rising Tides Competition, 2009

Drew Adams and Fadi Masoud

For the Bay Area, California and beyond the Delta is a unique and significant agricultural, economic and freshwater resource. This project argues for a Living Levee System expandable as multiple lines of defense to prevent a catastrophic intrusion of saltwater into the Delta. The system of basins allows it to operate as a permeable barrier responsive to salinity levels, ecosystem requirements, changing sea levels over time and normal flows at the Bay-Delta interface. The water pressure of a new freshwater reservoir at Sherman Lake is further used to buttress against sea rise while increasing both storage capacity and habitat area. This proposal is intentionally aligned with regional objectives of increasing water security as well as ecosystem and levee integrity.
