LA River Army Corps Study | Los Angeles River Revitalization

The Los Angeles River Ecosystem Restoration Feasibility Study

The City of Los Angeles (City), in conjunction with the U.S. Army Corps of Engineers (Corps), has prepared the Final Integrated Feasibility Report (IFR), which includes the Final Feasibility Report and Environmental Impact Statement (EIS)/Environmental Impact Report (EIR) for the proposed Los Angeles River Ecosystem Restoration Project. Under the National Environmental Policy Act (NEPA), the Final IFR is available for a 30-day review period, starting Friday, October 2, 2015. Please see the notice from the Corps listed below for details.

The proposed Project involves 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 considered include creation and reestablishment of historic riparian strand 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 connectivity to ecological zones, such as the Santa Monica Mountains, Verdugo Hills, Elysian Hills, and San Gabriel Mountains. Restoration includes the reintroduction of ecological and physical processes, such as a more natural hydrologic and hydraulic regime that reconnects the river to historic floodplains and tributaries, reduced flow velocities, increased infiltration, improved natural sediment processes, and improved water quality. The proposed Project also includes opportunities for passive recreation that is compatible with the restored environment.

Certification of the Final IFR and approval of the proposed Project will require consideration by the City's Board of Public Works, City Council Committees, and full City Council. These meetings have not yet been scheduled and are expected to be held during the first quarter of 2016. Please note however that this schedule is subject to change. Schedule updates will be posted on this website and the Bureau of Engineering's Environmental Management Division website: http://eng.lacity.org/techdocs/emg/lariver.htm. In addition, the official schedule and meeting agendas for the City Council and Council Committees are available at the City website: http://www.lacity.org/government/ElectedOfficialOffices/CityCouncil/CouncilCalendar/index.htm
