Pacific Coast Highway wastewater pipe project expected to clog traffic
The Coastal Interceptor Relief Sewer System is intended to cut down on the amount of pollutant-carrying stormwater reaching the ocean.
Work will begin at the south end of the project, near the Annenberg Community Beach House in Santa Monica, and extend north nearly to Temescal Canyon Road, said officials with the Department of Public Works.
From Monday to Friday, workers will close up to two southbound lanes of PCH between Entrada Drive and the Annenberg Community Beach House at night.
Survey work will take place from 9 p.m. to 5 a.m. One southbound lane will remain open at all times. Northbound traffic should not be affected, public works officials said. All lanes will reopen in time for morning rush hour, they said.After Friday, work affecting highway traffic will stop for a month until sewer installation begins April 11.The new, 4,500-foot pipeline will run alongside the existing Coastal Interceptor Sewer, providing increased flow capacity from eight newly completed diversions to the Hyperion Treatment Plant in Playa del Rey.
The system upgrade will help keep urban runoff from pouring directly into the ocean year-round, helping the city comply with water quality regulations, officials said.
Regular work hours will be 7 a.m. to 4 p.m. and 9 p.m. to 5 a.m. Mondays through Fridays and some Saturdays. Construction also is expected to create dust, noise and loss of beach parking during nonsummer months. A detour for cyclists will be available, officials said.
Highway users users are encouraged to consider alternate routes. Project updates will be available on Twitter @PCHPartners.
The project is being 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.
