A partnership between the City of Los Angeles Bureau of Engineering, Los Angeles Mayor Eric Garcetti’s office, AECOM, Gruen Associates, Chee Salette, WSP,  CH2M, Mia Lehrer + Associates (MLA), and Tetra Tech has produced preliminary visioning plans for a segment of the Los Angeles River running through Downtown Los Angeles.

The dramatic proposals aim to reconfigure a several-mile stretch of the concrete-lined river running from the southern tip of the Frogtown neighborhood north of Downtown to the Redondo Junction at its far southern end. Each of the seven teams was given a separate segment of the river to reconfigure and asked to take into account river-adjacent projects currently under development like BIG’s 670 Mesquit, among others. The teams were also asked to anticipate future planning approaches, including private-public partnerships and a potential extension of the Red Line subway to the Arts District. The proposals, according to a project website, are meant to focus on increasing pedestrian connectivity to the river while also “embracing bold, world-class design.”

Gruen Associates, Barclay to Spring Street:

Gruen Associates’ scheme seeks to reconfigure a narrow stretch of riverfront between Interstate 110 and the northern border of Chinatown by covering over an existing rail yard with a meadow and elevated public paths.

WSP, Spring Street to Cesar Chavez Avenue:

WSP’s proposal aims to create a series of stepped terraces that gradually meet the existing river bottom. The terraces expand as they reach the river, creating a broad, swoopy promenade.

CH2M, Cesar Chavez Avenue to 1st Street:

CH2M’s scheme creates a dramatic creek just south of Interstate 101 that rises up to meet the northern edge of the Arts District neighborhood. Renderings included with the proposal showcase broad bicycle and pedestrian paths as well as integrated seating and meandering trails.

Chee Salette, 1st Street to 4th Street:

Chee Salette’s proposal calls for a densely-packed sculpture garden sandwiched between Michael Maltzan Architecture’s (MMA) One Santa Fe complex and the L.A. River. The scheme features a river crossing that traverses the L.A. River’s bottom. Like the previous concepts, the scheme envisions placing a broad, stepped cap over the existing Metro rail yard that runs parallel to the waterway, where the Red Line extension would go.

Mia Lehrer + Associates, 4th Street to 7th Street:

MLA’s proposal extends work the firm has proposed for the adjacent 670 Mesquit project—MLA is landscape architect for that project, as well—by adding a riverine forest, wetlands, and stormwater filtration pools to the eastern banks of the river. The scheme also envisions creating a connection between the forthcoming 6th Street bridge park underneath the new MMA-designed 6th Street bridge and the nearby Hollenbeck Park.

AECOM, 7th Street to Olympic Boulevard:

The AECOM proposal aims to utilize a network of new pedestrian bridges over the river to connect the western and eastern banks of the river around a segment of the Arts District that has seen several new development proposals in recent months, including a new SoHo House outpost and an 110-unit live/work complex by Studio One Eleven. The AECOM scheme proposes a series of elevated park islands resting on diminutive feet and focuses on improving a Department of General Services-owned lot with demonstration gardens and a new solar farm.

Tetra Tech, Olympic Boulevard to 26th Street:

The scheme for the final leg of the study area includes the grounds surrounding the vacant Sears, Roebuck & Company Mail Order Building, which is currently slated to be redeveloped by Izek Shomof into a mixed-use complex. The Tetra Tech scheme envisions a new bridge at East Washington Boulevard over the river as well as a series of terraced gardens along the western banks of the river as well as a covered promenade along the eastern banks.

No word yet on which, if any, of these proposals will actually be built. A budget for the bridge-heavy collection of ideas has not been released. See the LA River Design Dialogue (3D) website for more information.
