The new home of the Golden State Warriors is in the Mission Bay neighborhood of San Francisco. Originally a shallow bay off the San Francisco Bay, the site was reclaimed in the late 1880s to early 1900s. The subsurface stratigraphy consists of poorly placed fill, weak and compressible Bay Mud, very dense Colma formation sand, moderately strong Old Bay Clay, and Franciscan bedrock. Liquefaction, lateral spreading, and consolidation are all hazards at the site. This talk will present the history of Mission Bay, subsurface conditions, geologic hazards and geotechnical issues, and the foundation solutions for support of the new Chase Center development. In addition, the presentation will provide an overlook of the construction of the shoring and foundation system for the new arena complex.
