Memorial Stadium
Further north the fault passes under the lengthwise midline of the football field of California Memorial Stadium at the University of California, Berkeley. Fault creep since 1923 offset the original walls at the north and south ends 13 inches (33 cm).
Extensive upgrades over a recent eighteen-month interval have addressed the life safety issues,[34] including replacement of the football players' facilities, and an extensive seismic retrofit of those sections not subject to fault shearing. The work was the subject of several lawsuits from neighborhood and environmental groups, who were concerned about such extensive construction on top of a major earthquake fault. During the reconstruction, the Cal Bears have played at AT&T Park in San Francisco for one season.[35] Some information concerning the retrofit is available here.[36] The modifications completed in Summer 2012 involved the cutting of the stadium into four independent sections, followed by the demolition of the two segments directly over the rubble zone. The north and south ends are formed of new bridging sections that rest upon floating mats (foundations that do not penetrate the surface, rather sitting upon plastic sheets over level graded gravel and sand) where they pass over and near the fault, with appropriate sliding connections between the sections for the safety of spectators and the ability to absorb the relative rotation between the east and west fixed sections and the and new north and south mobile sections.
