The City Trunk Line South – Unit 3 (CTLS-3) Project consists of the installation of approximately 10,250 linear feet of 60-inch diameter welded steel pipeline and appurtenances. The project route is along Whitsett Avenue from Vanowen Street to Magnolia Boulevard in the North Hollywood area of Los Angeles. Two construction methods will be used for construction:
- Open-Cut: 6,064 ft.
- Pipe Jacking: 4,186 ft.
The CTLS-3 Project will be divided into 14 different Work Areas (WA). Dividing the project into multiple work areas will concentrate the impact of the construction to those specific sites. The project will move in a linear fashion, moving from one area to another, over the project duration. Pipe-jacking construction methods were selected to be used and implemented along major key intersections where commercial land uses are located to alleviate traffic impact.
Project Background
CTLS-3 is the third of six units of the City Trunk Line South (CTLS) Project, which is part of the LADWP's aggressive Capital Improvement Program to replace the City's aging water infrastructure system. The CTLS Project is a replacement of approximately 42,000 feet of 51-inch to 72-inch diameter riveted steel City Trunk Line from the intersection of Canterbury Avenue and Nagle Avenue to Franklin Tunnel near Coldwater Canyon, south of Ventura Boulevard. The new trunk line will provide a more reliable supply of water to the area and will allow greater operational flexibility of the water distribution system in the City of Los Angeles.
