Bair Island Restoration, San Mateo County
Workers had to contend with bay muds, limited site access and protected wildlife species during the tidal restoration project for three islands comprising Bair Island, a 2,600-acre former salt pond within the Don Edwards San Francisco Bay National Wildlife Refuge—the largest urban wildlife refuge in the U.S. Contractors carefully phased the work to lessen effects of sedimentation and currents on local shipping channels and recreational sites. Using low-impact equipment, the construction team completed the work during short-duration tidal windows. To avoid spending $8 million for the 1 million cu yd of fill needed for the restoration, the team partnered with local contractors and allowed them to dump clean fill from their projects at Bair Island rather than hauling it to a distant landfill.
