The Century Trunk Line Unit 1 project is an important Water System infrastructure investment that will provide additional capacity, system flexibility and greater reliability to customers at LAX and across the City of Los Angeles. LADWP will replace an existing water pipeline originally installed in 1937 on Century Boulevard that is operating past its useful service life.
Approximately 10,880 feet of 24 and 48 inch diameter new earthquake resistant ductile iron pipe (ERDIP) will be installed, increasing resiliency during seismic events. ERDIP joints are designed to resist joint separation and allow for expansion and deflection.
Construction Information LADWP and Los Angeles World Airports (LAWA) are closely coordinating the Phases of construction with LAWA’s Landside Access Modernization Program (LAMP) projects to take advantage of opportunities to minimize impacts to traffic, businesses and residents.
Phase 1 is located primarily on 98th Street and will be installed by an LADWP contractor. Access to businesses will be maintained at all times. Advance notice of alternative traffic patterns and parking restrictions to accommodate construction will be provided to affected businesses.
Phases 2 and 3 are located primarily within future LAMP roadways. These phases will be constructed by LAWA’s contractors, in coordination with LAMP projects.
Phase 1: Summer 2019 – Summer 2020
