The ARBOR study, for "Alternative with Restoration Benefits and Opportunities for Revitalization," is touted to be the start of ambitious changes to the Los Angeles River, which could affect not just the riverbanks, but the riverbed itself.
The $9.71-million study was initiated in 2006 at the behest of the U.S. Congress. It aims to identify ways in which the ecology could be restored along the river, while still ensuring flood protection for the city.
The ARBOR study initially looked into the 32-mile stretch of the river between San Fernando Valley and the City of Vernon, but its scope has now focused on the 11-mile portion that connects Griffith Park to downtown Los Angeles. Soft-bottomed in some sections, it is the area the Army Corps has determined to have the greatest potential for eco-system restoration.
