Availability of a Draft Integrated Feasibility Report (Feasibility Study/Environmental Impact Statement/Environmental Impact Report), Los Angeles River Ecosystem Restoration Study, City of Los Angeles, Los Angeles County, CA
The U.S. Army Corps of Engineers (Corps) in conjunction with the City of Los Angeles (City) announces the availability of a Draft Integrated Feasibility Report (IFR), which includes a Draft Feasibility Study (FS) and Environmental Impact Statement/Environmental Impact Report (EIS/EIR) for the Los Angeles River Ecosystem Restoration Study, Los Angeles County, CA, for 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 includes 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 also 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 study also evaluates opportunities for passive recreation that is compatible with the restored environment. A Notice of Intent for the EIS/EIR was published on November 28, 2008 (73 FR 72455).
