The LA River Master Plan

Los Angeles County is updating the 1996 LA River Master Plan to create a plan that addresses the entire 51-mile LA River, and we want you to be involved!

The County of Los Angeles has conveyed a world-class team to help update the LA River Master Plan, a comprehensive approach covering all 51 miles of the River. The effort was launched to update the original 1996 master plan, synthesizing more recent ideas for portions of the River and bringing a comprehensive vision to the transformation of the LA River.

The team is led by LA County Public Works with support from Geosyntec, the engineering firm responsible for the technical water and engineering elements of the Master Plan. Joining Geosyntec are the landscape architecture and planning firm OLIN and the design firm Gehry Partners. Nonprofit River LA leads the coordination of an extensive community engagement and outreach process. Street Level Advisors, Kearns & West, 72 & Sunny, and Mosaic Strategies Group are also a part of the LA River Master Plan team.

The River is for All of Us

Will You Share Your Story?

River Stories show authentic community members’ stories, to hear their hopes and their concerns for the revitalization of the river. We will gather stories from a broad set of river users, residents living adjacent to the river, and from individuals who are passionate about LA River issues and our communities.

The Planning Process

The LA River Master Plan Update invites the public to participate and engage with the planning process in multiple ways, including the Steering Committee Meetings.
