This paper presents some of the seismic considerations used for the improvements at Berths 225 to 229 at the Port of Los Angeles. The design of the improvements was complicated by the presence of an active fault (the Palos Verdes Fault) located beneath the site. The actual location of this fault could not be determined. The project design acknowledged the potential of an active fault beneath the site, developed geotechnical and structural design criteria to mitigate these seismic effects, and used probabilistic procedures to quantify the risks associated with strong ground motion and ground surface rupture.
