The Los Angeles County Department of Public Works will hold three public meetings next month about the removal of 2.4 million cubic yards of sediment from the Arroyo Seco’s Devil’s Gate Dam.
The project, necessitated by surplus sediment that flowed into the reservoir in the wake of the 2009 Station Fire, is scheduled to take place over several years.
County officials recently signed off on the environmental report required by state law.
The idea is remove the sediment to make room for more and to be able to control debris flows during downpours that turn the normally dry riverbed into a torrent. The Arroyo Seco is a major tributary to Los Angeles River, and the dam, built in 1920, was the county’s first attempt to control downstream flooding
Most of the work — likely to start in 2016 — would be done in April and December, with heavy-duty trucks hauling away sediment between 7 a.m. and 3:30 p.m. The county Board of Supervisors has the final word in approving the project.
Here’s a rundown of the upcoming meetings:
- Nov. 1 at 1:30 p.m. in the auditorium at John Muir High School, 1905 Lincoln Ave.
- Nov. 3 at 6:30 p.m. at Jackson Elementary School, 593 W. Woodbury Road
- Nov. 6 at 6:30 p.m. in the Maple Room at Descanso Gardens, 1418 Descanso Drive.
