LADWP’s Foothill Trunk Line – Construction Update (Video)

Traffic Impacts on Foothill Boulevard Between Maclay Street and Hubbard Street

LOS ANGELES (January 9, 2018) — The Los Angeles Department of Water and Power (LADWP) announced that a portion of Foothill Boulevard – from Maclay Street to Hubbard Street – will be closed to northbound traffic for about 24 months as crews work on Phase 2 of the Foothill Trunk Line Project. Traffic along this narrow section of Foothill Boulevard will be limited to one lane of southbound traffic from January 6, 2018 to December 2019 to ensure crew and public safety. Northbound traffic will be detoured to Glenoaks Boulevard at Maclay Street.

Foothill Trunk Line is a major water pipeline used to transport large amounts of water serving the Sunland/Tujunga area of the City of Los Angeles. LADWP will replace a 3-mile section of the pipeline, referred to as Foothill Trunk Line Unit 3. Originally built in the 1930s, the existing pipeline ranges in diameter from 24 to 36 inches and will be replaced with a new 54-inch diameter pipeline to increase capacity and allow increased water flow, improving water quality as well as system flexibility and reliability.

Replacing smaller, aging steel pipe with welded steel and an Earthquake Resistant Ductile Iron Pipe (in designated areas) designed to flex with the movement of the earth, ensures water reliability.

The construction route begins on Terra Bella Street in Pacoima and continues northwest on Foothill Boulevard to its end near Hubbard Street in Sylmar. Construction of the pipeline is divided into 19 distinct Work Areas. Each Work Area is approximately 700-1,200 feet in length and will range between 4 and 10 months of construction at each location.

Phase 1 is being constructed with welded steel pipe and includes work areas 13 to 19. Completed work areas include 13, 14, 16 and 17. Work Area 18 is expected to be completed in May 2018.

Phase 2 is being constructed with Earthquake Resistant Ductile Iron Pipe and includes work areas 1 to 12. Work area 4 launched on January 6th (see above for map of construction areas).
