2020 LA River Master Plan

EIR - Draft EIR
Document Description
The proposed Project builds on the adopted 1996 Master Plan and other regional planning studies since then. 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 Project proposes six categories of project improvements, or “kit of parts” (KOP): KOP Category 1: Trails and Access Gateways; KOP Category 2: Channel Modifications; KOP Category 3: Crossings and Platforms; KOP Category 4: Diversions; KOP Category 5: Floodplain Reclamation; and KOP Category 6: Off-Channel Land Assets. Each KOP category includes a recommended collection of design components that can be implemented individually or in any combination. In addition, the 2020 LA River Master Plan includes a series of smaller common elements and Design Guidelines.
