South Bay Salt Pond Tidal Wetland Restoration Phase II Planning

This project funded completion of the planning and environmental documentation required for the construction of Phase II restoration projects. When Phase II projects are complete at the Ravenswood and Alviso complexes, an additional 1005 acres of tidal marsh and 60 acres of managed ponds will be restored. Phase II restoration projects include climate change adaptation features, such as large transition zones, elevation heterogeneity and plans for inland marsh transgression. Funding of these activities will keep the Conservancy’s schedule of beginning Phase II construction projects in 2016.
