The City Trunk Line North (CTLN) Project would replace the northern section of the Los Angeles City Trunk Line (LACTL) with approx 33,000 lf of 54-in diameter trunk line. The proposed CTLN alignment would follow the alignment of the LACTL at its northern and southern ends, where the new line would be slip-lined into the existing LACTL. The CTLN would be realigned to the east of the LACTL, primarily in Arleta Ave, for the majority of its length. The realigned sections would be constructed using an open trench method. The CTLN would be built in two units. Unit 1 would extend from the Van Norman Complex to the intersection of Arleta Ave and Terra Bella St, a distance of approx 21,000 ft. Unit 2 of the CTLN would extend from Terra Bella St to the CTLS in Canterbury Ave, just west of Tujunga Spreading Grounds, a distance of approx 11,800 ft.
