Document Description
In December 2006, the EBMUD Board of Directors approved the Water Treatment and Transmission Improvements Program (WTTIP) and certified the Environmental Impact Report (EIR) on the WWTIP. Since then, EBMUD has advanced the design of some original WTTIP projects and is now proposing to modify one of those projects - the Happy Valley. Pipeline in the City or Orinda - in order to reduce traffic disruption during construction and address reliability problems with an existing pipeline. Construction of the pipeline is occurring in two phases: Phase I and II. Construction of Phase I on Miner Road between Oak Arbor Road and Lombardy Lane was completed during the summer months of 2009. The proposed pipeline alignment for Phase II consists of three distinct segments of new 16-inch-diameter water pipeline. The first segment originates at the end of the Phase I alignment at Miner Road and Lombardy Lane and ends at the intersection of Miner Road and Tiger Trail Court. The second segment follows two existing District right-of-ways between Miner Road and Van Ripper Lane that traverses a ravine and Lauterwasser Creek. After crossing Lauterwasser Creek, the third segment follows Van Ripper Lane easterly and ends at the intersectionof Van Ripper Lane and Lombardy Lane. The District has determined that road closure with restricted would access would be necessary for pipeline installation on portions of Miner Road and on Van Ripper Lane. Pipeline construction in public roadways is proposed to occur from 9:00 a.m. to 9:00 p.m. Monday through Friday within District right-of-ways between 8:00 am to 6:00 p.m. Monday through Friday. Construction would commence when the school summer vacation being in 2013. Consistent with CEQA, the SEIR evaluates environmental impacts associated with the proposed pipeline alignment for Phase II.
