This winter, the Army Corps of Engineers will begin dredging the L.A. River from Griffith Park to the 110 Freeway area. By the time the project ends, nearby third graders will be in college. About 50% of the sediment will be removed during the 10-year project, according to Stephen Baack, a public affairs specialist with the U.S. Army Corps of Engineers’ Los Angeles District. Work will begin with excavation and invasive species removal, he added. According to Baack, $18 million has been allocated for the project, though more money could come in later. The next step involves awarding a contract to the entity that will do the work.
