San Francisco Bay Delta

South Bay Salt Pond Restoration, Phase II at Ravenswood

This project will restore and enhance wetlands in the Ravenswood Pond Complex as part of a second wave of implementation at the South Bay Salt Ponds (SBSP). As a result of this project, 280 acres of tidal wetlands will be restored, 60 acres will be maintained as pond habitat, tidal circulation through a 10 acre remnant tidal slough will be improved, and 15 acres of upland refugia will be created. Working with multiple federal, state, and local partners the SBSP Restoration Project is using innovative and cost-effective restoration methods to improve wetland habitats on a significant scale. The restoration design will create long-term, self-sustaining tidal wetlands, a transitional zone for accommodating sea level rise, and uplands that provide valuable habitat for special status species.
