PCH — Officials with the city of Los Angeles warned drivers Friday that a $10 million wastewater pipe project in the Pacific Palisades will impact traffic along Pacific Coast Highway through the end of next year.
The Coastal Interceptor Relief Sewer system is intended to cut down on the amount of pollutant-carrying stormwater reaching the ocean.
The work will affect southbound traffic along PCH intermittently through the end of 2012, according to the Department of Public Works.
Work will begin at the south end of the project, near the Annenberg Community Beach House, and will extend northward to just south of Temescal Canyon Road.
From Monday to March 11, workers will close up to two southbound lanes along PCH between Entrada Drive and the Annenberg Community Beach House at night.
Survey work will take place 9 p.m. to 5 a.m. One southbound lane will remain open at all times, and no impacts to the northbound traffic are expected. And all traffic lanes will reopen in time for the morning rush hour, the DPW reported.
After March 11, work affecting highway traffic will stop for a month, until the installation work to install the sewer begins on April 11.
The new 4,500-foot pipeline will run alongside the existing Coastal Interceptor Sewer, and will provide increased flow capacity from the eight newly completed Santa Monica Bay low-flow diversions to the Hyperion Treatment Plant.
The system upgrade will help keep urban runoff from flowing out into the ocean year-round, helping the city comply with water quality regulations, officials said.
Regular work hours are 7 a.m. through 4 p.m.; and 9 p.m. through 5 a.m., Mondays through Fridays and some Saturdays.
At least two southbound traffic lanes will remain open during daytime work, and at least one lane at night. Other construction impacts include “dust, noise, loss of beach parking during the non-summer months, and a detour option for cyclists,” the DPW reported.
PCH users are encouraged to consider alternate routes. Project updates are available on Twitter @PCHPartners.
The pipe’s design and construction are managed by the Bureau of Engineering. The sewer pipe project and others are funded by the voter-approved Proposition O Clean Water Bond of 2004. The $500 million bond finances 32 stormwater improvement projects across Los Angeles to help the city comply with state and federal water quality mandates for its water bodies.
