Corps river and creek cleanup project removes 575 tons of debris
A worker carries a bundle of Arundo donax, an invasive giant reed that can grow a foot or more daily. Arundo was used in the encampments as a construction material for makeshift fencing and huts. A total of 575 tons of debris were removed during the two-week project. The U.S. Army Corps of Engineers Los Angeles District cleared about 120 acres of San Jose Creek and San Gabriel riverbanks.
