Los Angeles County keeps environmental activists and media off the site where the 11 acres of oak tree woodlands are being bulldozed near Wilderness Park. It is called Santa Anita Dam Sediment Placement Site. Activists were unable to save the area from becoming a debris basin.

Hollywood actors Ed Begley, Jr. and Daryl Hannah called on prosecutors to drop a trespassing case against the group of tree-sitters who have become known as the "Arcadia 4." The four climbed into oak trees on January 12, 2011 while Los Angeles County bulldozers destroyed an 11-acre woodland around them. Begley rallied with supporters outside Los Angeles County District Attorney Steve Cooley's downtown headquarters. The four are John Quigley of Glendale, Julia Jaye Posin of Venice Beach, Travis Jochimsen of Lancaster and Andrea Bowers of Los Angeles. The trees were cleared to make room for a sediment site.
