Public Works to Hold Virtual Meeting on Devil’s Gate Southeast Improvement Project

The LA County Public Works Department will hold a virtual meeting at 6 p.m. on Jan. 31 on the Devil’s Gate Southeast Improvement project.

Over the past three years, the county worked to remove 1.7 million cubic yards of sediment from the Devil’s Gate Dam Reservoir.

The project also provided flood relief to communities that have endured nearly a decade of elevated flood risk along the Arroyo Seco, the project has established a permanent stormwater maintenance area that allows for the creation of 70 acres of enhanced habitat and recreational opportunities for local communities.

The project has moved into the next phase which includes the entrance improvement at the southeast section of Devil’s Gate.

A large amount of sediment had not been removed from the Devil’s Gate reservoir since 1994 when workers hauled out 160,000 cubic yards of soil and debris. An additional 1 million cubic yards of soil and debris were dumped into the basin by the Station Fire in 2009, which burned more than 160,000 acres in Altadena, Pasadena, La Cañada Flintridge, and Acton.

Devil’s Gate is the oldest dam constructed by the L.A. County Flood Control District, providing flood protection for the cities of Pasadena, South Pasadena and Los Angeles.

Local residents expressed concerns about idling trucks and excessive dust emanating from the worksite, prompting study from the Pasadena Public Safety Committee. L.A.County Supervisor Kathryn Barger said last month she is monitoring the situation closely.
