The Los Angeles Department of Water and Power (LADWP) proposes to install approximately 23,300 linear feet (LF) of a 36-inch diameter underground pipe along Victory Boulevard, Topham Street, and Oxnard Street, in the west San Fernando Valley area of the City of Los Angeles. The installation of the new 36-inch diameter trunk line (referred to herein as the Topham Trunk Line Replacement [TTLR] Project or the proposed project) would replace the aging and deteriorating existing 24-inch Topham Trunk Line to provide greater operational flexibility for water flow and delivery and to improve system redundancy and resiliency. The proposed project would also include approximately 6,599 LF of new 12-inch diameter underground distribution mainline that would connect the proposed TTLR Project to the existing distribution system on Mason Avenue, Victory Boulevard, and Topham Street. In addition, the proposed project would include approximately 3,429 LF of new 16-inch diameter underground distribution mainline that would replace the existing 8-inch diameter distribution mainline on Tampa Avenue, south of Topham Street.
