Document Description
SF Planning Commission certified the Peninsula Pipelines Seismic Upgrade Project FEIR, Case No.2011.0123E, on Oct 17, 2013. The project analyzed in the FEIR consisted of seismic upgrades to regional water facilities at five locations on the SF Peninsula, including in the Town of Colma, and the cities of South SF, San Bruno, and Millbrae in San Mateo County. Following the certification of the FEIR, the SF Public Utilities Commission (SFPUC) approved the project on Oct. 22, 2013. SFPUC previously identified areas on the San Francisco Peninsula that are susceptible to liquefaction, ground shaking, and landslides. As a result of these studies, the SFPUC identified five water pipeline segments in need of seismic improvements, which is referred to as the Adopted 2013 Project. These five sites included projects at the following project sites: Colma Site; South SF Site; San Bruno North site; San Bruno South site; and the Millbrae site. These pipelines, part of the regional water system owned and operated by the City and County of SF, are the San Andreas Pipeline No. 2 (SAPL2), San Andreas Pipeline No. 3 and Sunset Supply Branch Pipeline. The project construction activities consisted of replacement and stabilization of pipeline segments, injection of grouting to fill voids under pipeline segments, the installation of pipe supports, and tree removal. The project included the construction and seismic upgrades of 4,680 linear feet and included a total construction area of 11.48 acres. Both open trench and jack-and-bore construction techniques were used to construct the water pipeline segments. In San Bruno two segments of SAPL2 were replaced.
