The Napa River Salt Marsh Restoration Project is a pioneering effort to restore 10,000 acres of former salt ponds, remnant sloughs, fringing marsh and levees to tidal marsh and other valuable habitats in the North Bay of San Francisco. The project also provides wildlife-oriented public access. The Napa Sonoma Marsh Restoration Group provides an ongoing forum for information sharing about this and other projects in the area.

San Francisco Bay has lost an estimated 85 percent of its historic wetlands to fill or alteration. This dramatic decline in tidal marsh habitats has caused populations of marsh-dependent fish and wildlife to dwindle and has also decreased water quality. Now nearly complete, the Napa River Salt Marsh Restoration Project provides an opportunity to begin to reverse these trends and improve the health of San Francisco Bay for years to come.
The State Coastal Conservancy played an important role in this project, from contributing to the funds for acquisition of the land to leveraging $3 million in federal funds to complete a feasibility study and final environmental document. The Conservancy partnered with other state agencies on Phases 1 and 2 of implementation, tidal restoration of 3,000 acres and enhancement of an additional 1,800 acres of wetlands.
State agencies also led the draft design of the third and final phase of the project, 2,000 additional acres and a recycled water project to dilute saline water in the former salt ponds. After entering into a project agreement with the California Department of Fish and Wildlife, the U.S. Army Corps of Engineers began construction of Phase 3, which is mostly complete.
Ponds 3, 4 and 5
Ponds 1/1A and 2
Ponds 6/6A, 7/7A and 8
Note: remaining acreage consists of fringing tidal marsh, sloughs and levees.
Scientists will continue to collect and report data to support adaptive management of the site for 15 years after project completion. Wildlife observations have demonstrated a positive, immediate wildlife response to the newly restored areas. Monitoring surveys to date show heavy use of the site by waterfowl and shorebirds and a healthy population of salt marsh harvest mice. In addition, otters and bald eagles have been observed in the area.
OAKLAND, CA – This summer, in an innovative contract, sediment dredged from within the San Francisco Bay will be placed at Bay restoration sites to support healthy wetlands, rather than offloaded into the ocean or Bay. The U.S. Army Corps of Engineers (USACE or The Corps) maintains federal navigation channels in the Bay for shipping, […] (Read more on News Release: Dredged...)
