LOS ANGELES (CBSLA.com/AP) — County officials Monday worked to clean out storm catch basins throughout Southern California following a wave of late-season storms over the weekend.
Evacuation orders were lifted Sunday in Glendora and Azusa after an estimated 1,000 homes north of Sierra Madre Boulevard were evacuated over the weekend.
As the storm that battered the Southland tapered off, debris basins diverted several hundred thousand cubic yards of runoff material “that otherwise would have been in communities,” according to Bob Spencer of the Los Angeles County Department of Public Works.
Runoff channels first enter into catch basins before they merge into storm drains, which essentially act as overflow systems, according to city environmental officials. Some of the pollution entering storm drains can include fertilizers, cigarette butts, trash, pesticides, chlorine, automotive fluids, used oil, paint, chemicals, animal waste, and decomposing organic matter, officials said.
Spencer told KNX 1070 NEWSRADIO foothill residents who were spared any major damage can thank about 26 major debris basins throughout ranging in size from 35,000 cubic yards to as large as 100,000 cubic yards.
