Phase 1:  Los Angeles River Index

To date, the team has completed two phases of work. An initial investigation period started in late 2014 to determine a concept and hypothesis for more detailed study. This work was completed by the team entirely on a pro bono basis.
Work on Phase 1 began in January 2016 with $2.5 million in funding (and $500k pledged) of our $3.1 million Phase 1 budget through an intentional public-private partnership, with significant funding from both the philanthropic community, as well as state and local agencies. Phase 1 consisted of further public outreach, detailed data gathering and analysis, detailed hydraulic analysis, amongst other activities. The completion of Phase 1 is summarized in this website, in the form of the LA River Index.

Investigations from Phase 1 allow the technical teams to develop the approach for Phase 2 which will prioritize testing interventions in and along the LA River that is inclusive of the entire 51-miles and offers multi-layered environmental, economic and social benefit data.


Phase 2:  A 51-Mile Integrated Design Strategy

The primary discovery goal for Phase 2 is to fully maximize the potential of the river as a multi-benefit and transformational resource for our region while maintaining the capacity of our river as a flood control channel by creating floodable design concepts.

The Phase 2 collaboration between River LA, Gehry Partners, OLIN and GeoSyntec is currently considering:

  • Extensive outreach and public engagement.
  • Continued data gathering, research, analysis, and identification of potential benefits.
  • A single central information database (content management system CMS), providing the ability for coordinated efforts between decision-makers and policy-makers to use real-time. This will include layered data to inform the most impactful decisions for project implementation. The CMS also has a goal to house both 2D and 3D information as relates to the river.
  • A 51-mile framework for the LA River with the goal of creating a coordinated programmatic effort along the river’s entire length, and to suggest both generic and detail design possibilities at several locations along the river.
  • Concepts for funding opportunities and governance.

With this, we hope  to create a plan that will enhance the ability of existing work and plans to be implemented, and coordinate the focus of future planning efforts.
