BACKGROUND INFORMATION: The Central TCE/PCE Plume is bound by Pine Street to the north, Stockton Street to the east, Pleasant Avenue to the west, and Park Street to the south. Reports prepared by Langan Treadwell Rollo, the City's PCE/TCE consultant, indicate that the PCE plume has migrated southerly toward the intersection of Church and Tokay Streets. This project (Exhibit A) is intended to capture and contain the plume migration, and consists of a groundwater extraction well, granular activated carbon (GAC) treatment unit, a metal enclosure, electrical and site work, and other incidental related work, all as shown on the plans and specifications for the above project. The Central Regional Water Quality Control Board has reviewed and concurs with the proposed workplan. Staff has worked closely with Lodi Unified School District to minimize the impact to Needham School. The GAC treatment unit will be constructed in a steel enclosure placed entirely inside the public right-of-way. The project includes an element of drought resistant landscaping to soften the enclosure's appearance. The plans and specifications are on file in the Public Works Department. The planned bid opening date is January 21, 2016. FISCAL IMPACT: FUNDING AVAILABLE: There will be additional costs associated with the operations and maintenance of this facility that will be funded by the PCE/TCE fund.
