Santa Anita Dam sediment project is nearly complete but residents and activists continue to question Los Angeles County's intentions for demolishing the 11-acre Arcadia Woodlands 1.5 years ago. Following the removal of the trees on January 12, 2011, the Los Angeles County Department of Public Works has been moving mud and debris from the dam to the middle and lower sediment placement sites by a massive conveyor belt. Moving the dirt makes flood control and water conservation possible for the neighboring populations of Arcadia and Sierra Madre.
