Devil's Gate dirt removal plan may double in size
A public meeting is scheduled next month at the Rose Bowl to discuss a plan to remove as much as 4 million cubic yards of soil from the Devil's Gate Dam in Pasadena, some of which has been deposited since the devastating Station fire of 2009.
The Rose Bowl is directly in the path of storm water and debris restricted by the dam.
The amount of debris L.A. County is proposing to remove is nearly three times as much soil as originally planned and is part of a wider effort to clean out 87 tons of sediment from area dams over the next 20 years.
The Los Angeles County Department of Public Works initially planned to dig out 1.5 million cubic yards from Devil’s Gate in Hahamongna Watershed Park this summer, destroying 50 acres of woodland that’s grown on years of sediment deposits.
The Los Angeles County Board of Supervisors halted the project in March by ordering an environmental impact study. When that study begins, Public Works officials will be calling for removal of as much as 4 million cubic yards, the La Canada Valley Sun reported.
Removing only the 1.5 million cubic yards deposited after the August 2009 Station fire and subsequent winter storms may make for more work in the long run, said Gary Hildebrand, assistant deputy director of the agency’s Watershed Management Division.
In addition to Devil’s Gate, Public Works is planning to clean out four other dams inundated after the Station fire: Big Tujunga Dam, 10 miles north of Sunland; Cogswell Dam, along the west fork of the San Gabriel River; Pacoima Dam; and Morris Dam, off Highway 39.
