':. Seismic Vulnerability Study reliable immediately after a large magnitude earthquake on either the San Andreas or Hayward faults. As part of the design, we are considering the complete SFPUC transmission system seismic reliability, including reliability to each individual Redwood City turnout on existing BDPL 1, 2, 3 and 4, as well as future BDPL 5. For the SFPUC, G&E developed the fault crossing upgrade design for BDPL 3, 3A (new), and 4 pipelines where they cross the Hayward fault in Fremont at Mission Boulevard. This includes detailed planning for a new 72" pipeline (BDPL 3A) and retrofit of the existing 96" pipeline, outage planning, construction sequencing, etc. For the SFPUC, G&E was the engineer-in-charge for the seismic retrofit of the BDPL 1 and 2 pipelines where they cross the Hayward fault. This $10 million project was completed in 2003. G&E also performed the seismic evaluation of the existing BDPL 1 and 2 pipelines where they cross the Dumbarton Strait on a combination of 2,000 wooden trestles, underwater crossings and steel trestle bridge; we have developed plans to keep these pipes reliably in service for the next decade or so. We also evaluated in detail the seismic reliability of all the SFPUC pipelines where they cross the Calaveras fault, including preliminary design of the new seismic-tolerant Siphon 4. Proiects with Similar Issues as the Redwood City Seismic Improvement Study We have prepared U.S. nation-wide procedures for FEMA, the American Lifelines Alliance, ASCE, and the U.S. National Institute of Building Sciences for water system seismic vulnerability assessments. These have undergone substantive peer review by numerous experts, and can be considered the "state-of-the-practice" in this area. These books (cumulatively over 700 pages long) include: 2001: Water System Fragility. 2003: Fire Following Earthquake. 2005: Guidelines for the Seismic Design of Water Pipelines. These three books collectively represent the state-of-the-practice in seismic vulnerability assessments for water utilities. We have developed many capital seismic improvement programs for water utilities, and have made many presentations to Boards of Directors, the Public and other stakeholders in the decision making process. In the past three years, we have successfully obtained FEMA grant money for seismic upgrade for several water utilities, with typical funding between $1.5 million and $3 million for each proj ect. These upgrades cover items such as open cut reservoirs, concrete tanks, steel tanks, EBAA Flextend installations, building upgrades, pump station upgrades, equipment upgrades, remediation / upgrade of pipes at fault crossings. We are well able to develop a grant submittal on behalf of Redwood City for future FEMA PDM-C 2009 or 2010 grant programs (see optional task 8d).
