Construction Notice – Foothill Trunk Line, Work Area 8 Nearing Completion

On Saturday, December 10, 2022, crews completed the last pipe connection for Work Area 8 on the Foothill Trunk Line, in front of the shopping center, just south of the Pacoima Wash. From now through the end of the year, you will see the crew removing trench shoring, barricades, and equipment and then backfill the void. The crew is scheduled to pave and restripe the work area on Foothill Blvd on Saturday, January 7, 2023, weather permitting.

The next trunk line work area is #19, at the intersection of Foothill and Terra Bella, and is expected to begin fall 2023.

In advance of future trunk line work, you will see our district crews installing mainline pipe at the intersections of Foothill and Hubbard, Maclay, Arroyo, and Paxton. The first work area is at Hubbard and unlike the trunk line work you’ve seen along Foothill, our mainline construction areas will be set up only during working hours, with trenches covered at the end of each shift. Work hours are Monday – Friday, 9am to 3:30pm, with occasional Saturdays. These mainline work areas are scheduled to be completed in August 2023, prior to the start of Foothill Trunk Line Work Area 19.

We thank you for your patience and understanding while we work on this critical infrastructure improvement project.

Why is there Construction on Foothill Blvd in front of Home Depot?

The Sylmar 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 pipes 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.
