In partnership with the City of Los Angeles Bureau of Engineering and the Los Angeles Mayor Eric Garcetti's office, seven firms have released preliminary visioning plans for a segment of the Los Angeles river. Running through downtown, the seven-mile stretch begins at the southern tip of the Frogtown neighborhood and ends at Redondo Junction. Each firm was given a different segment to plan and was asked to consider river-adjacent projects already in plan as well as anticipated development along the stretch such as a potential extension of the Red Line subway. 

Working on the stretch from Barclay to Spring Street between I-110 and the northern border of Chinatown, Gruen Associates proposed reconfiguring the existing rail yard with a meadow and public paths. 

WSP's proposal of the stretch starting at Spring Street and continuing on to Cesar Chavez Avenue, involves a series of stepped terraces that gradually meet at the existing river bottom.  

CH2M's proposal continues on from Cesar Chavez to First Street and designs for a creek just south of the 101. Meeting the northern edge of the Arts District, they've incorporated bicycle and pedestrian paths into their plans for seating and

Continuing on toward Fourth Street,  Chee Salette proposes a sculpture garden besides Michael Maltzan's gigantic One Santa Fe complex and a river crossing. 

Mia Lehrer + Associates, whom have long been involved in the LA River revitalization, worked on a proposal for the stretch between Fourth and Seventh Street that will be adjacent to BIG's forthcoming 670 Mesquit, which the landscape architect is also working on. The plan adds a riverine forst, wetlands, and stormwater filtration pools. 

AECOM, put forth a colorful proposal for the section starting at Seventh Street and ending at Olympic. Utilizing a network of new pedestrian bridges, the scheme involves a series of elevated park islands. Down along the riverbed, when the river is dry, the space will become highly accessible to the public with programmatic uses. Neighboring the Department of General Services, the lot will be utilized for demonstration gardens and a new solar farm.

The last stretch has been designed by Tetra Tech and runs from Olympic to 26th Street. With the adjacent Sear, Roebuck & Company Mail Order Building slated for mixed-use development, their scheme calls for a new bridge at East Washington as well as a series of terraced gardens.
