Document Description
Note: Review Per Lead The U.S. Army Corps of Engineers (Corps) in conjunction with the City of Los Angeles (City) announces the availability of a Final Integrated Feasibility Report (IFR), which includes a Final Feasibility Study and EIS/EIR for the Los Angeles River Ecosystem Restoration Study, Los Angeles County, CA, for public review and comment. The study evaluates alternatives for the purpose of restoring 11 miles of the Los Angeles River from approximately Griffith Park to downtown Los Angeles while maintaining existing levels of flood risk management. Restoration measures include creation and re-establishment of historic riparian and freshwater marsh habitat to support increased populations of wildlife and enhance habitat connectivity within the study area, as well as to provide opportunities for regional connectivity to ecological zones such as the Santa Monica Mountains, Verdugo Hills, Elysian Hills, and San Gabriel Mountains. Restoration also includes the re-introduction of ecological and fluvial processes through a more natural hydrologic regime, which reconnects the river to historic floodplains and tributaries, reduces flow velocities, increases infiltration, and improves natural sediment processes.
