Map of the Alviso Pond replacement project showing restricted access and daily closures along the eastern levee trail around Ponds A12, A13, and A15. The image also includes messages stating that these areas are closed to hiking, fishing, and boating and that personal protective equipment is required in these areas.

Alviso Pond A12, A13, and A15 Levee Repair

Daily closures of maintenance access roads for levee fill and aggregate hauling and construction activities along Pond A12, A13 and Pond A15 between 7 A.M and 5 P.M weekdays. Truck traffic will enter the stockpile area through the Alviso Marina Park entrance. Trucks will be traveling along Pond A12, A13 and A15 levees to transport the materials to the repair locations. All trails will be accessible on weekdays when no hauling or construction is occurring. 

When: April 19, 2021 until June 11, 2021

This project will help maintain the protection of wildlife habitat, these sections of the levee system requires rehabilitation to restore the structural integrity of the pond system.

Bair Island  

Beginning in late June, Inner Bair Island will be experiencing construction activities while a temporary 1-mile long access road is constructed and utilized from the Whipple Avenue pedestrian entrance to the northwest end of Inner Bair Island. The Don Edwards San Francisco Bay National Wildlife Refuge is coordinating with Silicon Valley Clean Water on the next phase of their 48-inch Force Main Reliability Improvement Project.  This project is off-refuge but will require temporary access through the Bair Island Unit.  
The Whipple Avenue pedestrian access to the main Bair Island Trail will be narrowed and portions of the Bair Island Trail may experience temporary short closures in early July, but the Bair Island trail will otherwise remain accessible for the duration of the project. 
This work will not impact the official entry to the trail on Bair Island Road.  Upon completion of the project, the temporary road will be restored to native vegetation.
