Los Angeles River Revitalization

City Projects

The Los Angeles River Revitalization Master Plan (LARRMP) guides the City's policy and project implementation along the Los Angeles River and in its watershed. Information about the many completed projects that are open for use is available using the map above and at the Explore the LA River page.


Key Projects and Programs 

(Updated June 2017)


Taylor Yard "G2" Project

"Bending the River Back" Into the City Water Wheel

LARiverWay Design and Implementation

Albion Riverside Park

Los Angeles River Recreation Zone


The City’s Adopted Capital Improvement Expenditure Program includes a listing of projects that relate to the Los Angeles River revitalization effort, as reported by the City's Administrative Officer. The project listing includes projects for bridges, recreational bike paths, parks and associated facilities, and riparian restoration features.

LARRMP Priority Project List: This list is used to focus Los Angeles River Revitalization Master Plan implementation efforts on a subset of projects that have the potential to be implemented through partnerships and outside funding. The list is ordered by implementation time horizon, roughly as follows: near term (0-5 years), near-mid (5-10 years), mid (10-15 years) mid-long (15-20 years), and long-term (more than 20 years). However, should adequate funding become available, these estimated implementation time horizons would change. The list will be updated on a regular basis. This effort generally considers the approximately 240 projects proposed by the LARRMP.

Potential funding for revitalization projects include public/private partnerships, as well as grants and partnerships with federal, state, and county government. Several projects within the Los Angeles River watershed are also being funded by the City's Proposition O bond program for Clean Water, Ocean, River, Beach, Bay, and Storm Water Cleanup, passed in 2004.


Los Angeles County Projects

The responsibilities of the Los Angeles County Department of Public Works (LACDPW) include the design, construction, operation, maintenance, and repair of roads, bridges, airports, sewers, water supply, flood control, water quality, and water conservation facilities and for the design and construction of capital projects.

In 1991, after much attention to the River, the County of Los Angeles Board of Supervisors directed the County Departments of Public Works, Parks and Recreation, and Regional Planning to develop the County's Los Angeles River Master Plan. This Master Plan, completed and adopted by the Board of Supervisors in 1996, formulated a multi-objective program for the entire-52 mile River while recognizing its primary purpose for flood protection. Overall, the Master Plan advocates environmental enhancement, recreational opportunities, and economic development.

With similar goals, the City of Los Angeles' 2007 Los Angeles River Revitalization Master Plan builds upon the County of Los Angeles’ 1996 Los Angeles River Master Plan, but specifically focuses on the 32 miles of the River within the City. 

The County's 1996 Master Plan is overseen by an Advisory Committee of 50 members representing federal, state, city, and local agencies, and environmental and community groups. The Advisory Committee meets on a regular basis, and members are given the opportunity to review proposed projects. Project reviews are also performed by the Department of Public Works--the agency that issues construction permits--and the U.S. Army Corps of Engineers who ensures that the structural integrity of the river is not compromised.
Consistency between the City of Los Angeles' 2007 Los Angeles River Revitalization Master Plan and the LACDPW's 1996 Los Angeles River Master Plan ensures that projects along the River will help meet common goals and be mutually compatible.
