The Los Angeles River Ecosystem Restoration Project focuses on 11 miles of the river from the Headworks site in the San Fernando Valley to 1st Street in downtown Los Angeles. This project is an opportunity to bring back over 700 acres of critical riparian habitat to a river that has lost over 90% of what once existed, while maintaining the current level of flood protection. Specific features included are restoration of two tributary confluences, restoration of the Los Angeles Trailer and Container Intermodal Facility Site, significant removal of concrete and riverbed restoration, restoration of the freshwater marsh at the Los Angeles State Historic Park, and restoration and reconnection to the historic flood plain at Taylor Yard. This project was authorization within Section 1401(7) of the Water Resources Development Act of 2016.
