Document Description
The proposed Project is located along a 51-mile-long, 2-mile-wide corridor (i.e., 1 mile on each side) of the LA River in Los Angeles County and spans through 17 cities and unincorporated Los Angeles County areas (18 total jurisdictions). The river encompasses an 834-square-mile watershed and flows from its headwaters at river mile 51 in Canoga Park in the City of Los Angeles to river mile zero in the City of Long Beach, where the river meets the Pacific Ocean (Figure 1). The LA River was channelized during the late 19th and mid-20th centuries to protect lives and property from flooding as the LA region rapidly grew and transformed to a largely urbanized area. Today, approximately 1 million people live within 1 mile of the river.
