Daily interruptions and brief closures of public access trail crossings (including a section of the Bay Trail) for delivery of material to Pond A1 will take place between 7:30 A.M and 4 P.M weekdays. December 11, 2024, until January 31, 2025.
Truck traffic will enter the project area through the City of Mountain View’s Shoreline Park and into Pond A1. Trucks will be traveling along San Antonio Road, onto Terminal Boulevard, and then into Shoreline Park on paved trails. A new temporary access ramp will be built at the northern limit of Shoreline Park, adjacent to the Bay Trail, for material transport to the project area in Pond A1. Material will be used for construction access, habitat enhancements and levee fill. The Bay Trail and most Shoreline Park trails will be accessible on weekdays when no hauling or construction is occurring. A short section of Shoreline Park trail will be closed during times when material is being actively delivered to the pond. Temporary signs and flaggers will be placed at the Bay Trail, at relevant Shoreline Park trails, and at the Terminal Boulevard entrance to manage truck traffic and trail user access.
This project will help the implementation of the South Bay Salt Pond Restoration Project’s Phase 2 action at the Alviso-Mountain View Ponds. It will establish an access route and stockpile location for deliveries by haul trucks of fill material for the project construction, including wildlife habitat slopes and islands and for improvements to existing levees.
PG&E has planned maintenance work on the following dates. All work will be conducted via helicopter access. Extreme weather conditions may cause rescheduling.
R1 - December 5-7
Greco Island - December 5-8 and December 10-11
Bair Island - December 10
A3N and A3W - December 18

About Us
The nation's first urban national wildlife refuge national wildlife refuge
A national wildlife refuge is typically a contiguous area of land and water managed by the U.S. Fish and Wildlife Service for the conservation and, where appropriate, restoration of fish, wildlife and plant resources and their habitats for the benefit of present and future generations of Americans.
Learn more about national wildlife refuge sits on the southern end of San Francisco Bay. It is indeed a wildlife oasis in an urban sea. The refuge, created in 1972, was largely the result of grassroots efforts by the local community to protect the San Francisco Bay ecosystem. Today, it provides not only critical habitat for threatened and endangered species, but opportunities for people to enjoy the benefits of nature.
What We Do
Don Edwards San Francisco Bay National Wildlife Refuge was established to preserve and enhance wildlife habitat; protect migratory birds and threatened and endangered species; and provide opportunities for wildlife-oriented recreation and nature study for the surrounding communities.
Our Species
Fifteen habitat types exist on the Don Edwards San Francisco Bay National Wildlife Refuge, contributing to the diversity of wildlife on the refuge. More than 340 plant species and 280 species of birds call the refuge home, and millions of individual birds fly through the area during peak migrations. In addition to plants and birds, the refuge provides habitat for fish, mammals, reptiles, amphibians, and invertebrates!
