The Oakglade Debris Basin is a drainage structure, located above the intersection of Ridgeside and Oakglade drives, in the foothills of Monrovia. This structure is owned and operated by the Los Angeles County Flood Control District for the purpose of capturing mud and debris flows from the foothills to protect the life and property below.
During the last rainstorm, the basin accumulated nearly 3,000 cubic yards of mud and debris from the foothills that were recently scarred by the Bobcat Fire. As a part of maintenance and operations of this facility, the sediment needs to be hauled to ensure the basin maintains sufficient capacity for future rain events.
On Wednesday, Los Angeles County Public Works/Flood Control began sediment-hauling operations, where sediment is trucked from the basin at the top of Ridgeside/Oakglade to the disposal location within the Sawpit Wash area. Given the amount of debris that is within the basin, L.A. County estimates that this effort will take in excess of 300 truck trips, with a hope of completing approximately 50 per day. L.A. County estimates the project will take two weeks. Hauling efforts will be limited to Monday–Friday from 7 a.m. to 4 p.m. As work progresses, and should rain begin to be forecasted, the city may approve Saturday work.
Los Angeles County Public Works has distributed a notification to residents in the impacted area. Questions or concerns should be directed to the Los Angeles County Public Works Department:
