The County of Los Angeles has selected 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.

Who selected the Consultant Team?

The Los Angeles County Department of Public Works solicited proposals for project management from its on-call technical consultants. Of the firms that returned proposals, Geosyntec was selected as the successful bidder. The other team members are subcontractors to Geosyntec.

Who has oversight of Los Angeles County Department of Public Works?

The Los Angeles County Department of Public Works manages the project management, which includes the management of the consulting team. The steering committee is in an advisory role, and advises the consultants and the county on the project based on community input.

What are the roles of each of the team members?


  • Geosyntec is the lead consultant responsible for all technical elements, including hydrology, flood protection and other water and engineering issues. Geosyntec Consultants, Inc. is an award-winning, international consulting firm, known in the greater Los Angeles area for its knowledge of local watersheds, long-term strategic perspectives, innovative planning and modeling analyses (hydrologic, hydraulic, hydrodynamic, water quality, and groundwater modeling), project design and delivery, and project optimization and monitoring services.

What is the desired outcome of the plan?

How soon will real change be seen on the river?

There is daily progress on the river, including both formal and informal meetings and conversations about the work. There are a number of projects in development up and down the river!
