The Pacific Commons project is located on 875 acres in a redevelopment area of Fremont, California. A 390-acre portion of the site has been preserved for ecosystem protection and restoration. The restored ecosystem consists of a wetland-upland mosaic comprising vernal pools, connecting swales, other seasonal wetlands, and grasslands which includes occupied habitats for vernal pool tadpole shrimp, California tiger salamanders, burrowing owls, and several rare plant species including the endangered Contra Costa goldfields. Overall, this project involved the creation of an open space preserve including designing and constructing 174 vernal pools. The project has required close coordination with local, state, and federal agencies, and has been reviewed favorably by the U.S. Fish and Wildlife Service and California Department of Fish and Game. WRA continues to provide monitoring services for these restored and created habitats.
