SEISMIC DESIGN CRITERIA FOR SAN FRACISCO WATER SYSTEM IMPROVEMENT PROGRAM
The San Francisco Public Utilities Commission (SFPUC) manages a water system stretches from the Sierra Nevada Mountains to San Francisco. The system was built in the early to mid 1900s; many parts of this system are nearing the end of their working life. In addition, crucial portions of the system cross over or near three major earthquake faults in the Bay Area. The SFPUC, together with its 28 wholesale customers, launched a $4.3 billion Water System Improvement Program to repair, replace, and seismically upgrade the systems aging pipelines, tunnels, reservoirs, and dams. A major component of the program is the seismic improvement of the system. To meet the level of service for seismic recovery, general seismic requirements for design of new facilities and upgrade the existing facilities were developed. This paper provides an overview of the SFPUC seismic design criteria. It includes (1) general issues on level of service, performance goals and seismic performance classes, (2) seismic hazards, (3) design earthquakes, (4) criteria for various structures such as buildings and building-like structures, pipelines, soil retaining structures, underground structures, water retention structures, dams and reservoirs, and reservoir outlet towers.
