The proposed project would be located entirely within the existing road right-of-way. The properties adjacent to the proposed pipeline alignment include the following designations: public facilities, very low residential, low residential, low medium residential, medium residential, general commercial, community commercial, neighborhood office commercial, and highway oriented commercial.
The Los Angeles Department of Water and Power (LADWP) proposes to replace approximately 21,000 linear feet of the existing Roscoe Trunk Line (the Roscoe Trunk Line Replacement [RTLR] Project, also referred to herein as the project or proposed project). The RTLR would parallel the existing Roscoe Trunk Line within Roscoe Boulevard from Mason Avenue on the west to Louise Avenue of the east, in the west San Fernando Valley area of the City of Los Angeles. The proposed project would also include approximately 18,000 linear feet of a new 16-inch diameter distribution mainline, approximately 2,300 linear feet of 12-inch diameter replacement distribution mainline, and two new pressure regulating stations. All these proposed facilities would be located underground within the road right-of-way.
The proposed project would be located in the western portion of the San Fernando Valley in the City of Los Angeles. The replacement trunk line and mainline would parallel the existing Roscoe Trunk Line within Roscoe Boulevard from approximately Mason Avenue on the west to Louise Avenue on the east. Roscoe Boulevard, an east-west thoroughfare, forms the boundary between the communities of Northridge and Chatsworth to the north and Reseda and Winnetka to the south. The proposed project would also include a replacement distribution mainline within Reseda Boulevard between Roscoe Boulevard and Bryant Street. All these proposed facilities would be located underground within the road right-of-way.
