Allows for a restored connection between creek & marshland

Protecting people and property from San Francisco Bay to Highway 101

Design objective: 100-year creek flow, 50 years (26”) of SLR, 100-year tide, and 3’ of freeboard

• Protects over 1,000 parcels from creek flows and tides exiting channel

• Creates 14 acres of new marsh habitat• Enables new golf course and trails• Enables flood protection work upstream• Provides new, safer PG&E gas pipeline
