As authorized by the Assembly Bill 530, the State, in consultation with the Los Angeles County Board of Supervisors, appointed representatives to the Working Group, including elected officials and executive level members from the local cities, regional agencies, and community organizations serving the river corridor in April 2016.

The Working Group provided input and direction for the development of the Lower LA River Revitalization Plan . The Working Group convened for almost two years through 22 publicly held working group and 58 committee meetings to gather feedback and design a truly collaborative and inclusive process.
