Document Description
The Western Trunk Line Project would involve the replacement of a 23,300-foot portion of the Harbor Trunk Line within Western Avenue, from 59th Place to 121st Street. The proposed project would be located in the City of Los Angeles between 59th Place and 108th Street, and in unincorporated Los Angeles County between 108th Street and 121 st Street. In addition to the proposed trunk line replacement, the proposed project would also replace approximately 4,495 feet of 6-inch and 8-inch diameter water distribution mainline along Western Avenue. The water distribution mainline improvements would include the following: the replacement of 3,750 feet of existing 6-inch mainline with 12-inch line from 77th Street to Manchester Avenue; the replacement of 625 feet of existing 8-inch mainline with 12-inch line from 106th Street to 108th Street; and the installation of approximately 120 feet of 8-inch line to reconnect the existing 8-inch mainline on Western Avenue to the existing 8-inch line on Manchester Avenue. In order to maintain water pressures at specific intersections, the proposed project would also include minor improvements and the replacement of an existing regulator station, located at the intersection of Manchester Avenue and Western Avenue.
