Phase 2 Construction Underway
Alviso
Mountain View Habitat, Trails and Flood Protection Work
Construction is underway at a 275-acre Mountain View pond, Pond A1. It will be restored to tidal marsh habitat, with habitat enhancements, a new public trail and viewing platform, and a habitat slope that will also protect Shoreline Park from erosion. The former industrial salt ponds will eventually be opened to the Bay so nature can restore a rich tapestry of tidal marsh, channels and mudflats. The Restoration Project construction will also strengthen levees where needed to ensure flood risks are not increased. The City of Mountain View will also install erosion protection at key junctures with Shoreline Park edges.
Trail Closures and Disruptions for Alviso Construction
Construction and trucks are impacting trails, including the San Francisco Bay Trail, in Mountain View and near the community of Alviso.
Mountain View Shoreline
San Francisco Bay Trail and Shoreline at Mountain View park by Sailing Lake and Charleston Slough: Trucks may cause daily interruptions and brief closings of a trail on the west end of the Sailing Lake and a nearby portion of the Bay Trail as the trucks use the trail or cross. Public trails will remain open to walkers and bikers on weekends, and during weekday times when no hauling or construction is occurring. Trucks traverse Mountain View Shoreline Park along the west side of the Sailing Lake and cross the nearby Bay Trail. They may operate between 7:30 AM and 4 PM weekdays. See map below for truck route.
When: from late 2024 through 2027.
Mountain View Pond A1 Construction Vehicle Route
Alviso Marina and Environmental Education Center
Sections of the Mallard Slough Trail and Alviso Slough Trail are closed for construction of a flood-protection levee and habitat slope, part of the South San Francisco Bay Shoreline Project. The 4-mile-long levee is being completed to protect north San José, including the community of Alviso and the Regional Wastewater Facility, from rising seas and a 100-year coastal storm. The habitat slope is the next step. When intermittant work is underway, it will occur Monday through Friday, 7 a.m. to 5:30 p.m. and on limited weekends as necessary, except holidays. Local and brief trail closures may occur until mid-September to protect nesting birds.
When: through November 2028.
Don Edwards Phase 2 Construction Projects
Phase 2 Construction Completed and Celebrated
Ravenswood
The new Flyway Trail and Viewing Area was unveiled October 2024, connecting the City of Menlo Park's Bedwell Bayfront Park with the new Meta pedestrian bridge along the Bayfront Expressway. The opening of the half-mile trail at the U.S. Fish and Wildlife Service’s Refuge completes the Restoration Project’s Phase 2 construction at this 300-acre area of the Ravenswood Ponds. The trail provides views of ponds for ducks and shorebirds on one side, and the birdlife and newly restoring wetlands at Pond R4, which the Restoration Project breached to the Bay in December 2023.

Eden Landing Phase 2 Final Environmental Impact Report
The final document, released in spring 2019, describes the preferred plan for tidal marsh restoration, wildlife habitat improvements, new trails and flood protection on 2,270 acres of ponds near Union City. It analyzes environmental impacts of alternative plans for the area covering about half of the California Department of Fish and Wildlife’s Eden Landing Ecological Reserve. This final report also includes responses to public and stakeholder comments received on the Spring 2018 draft report.
