The City of Los Angeles has revealed preliminary designs for seven different downtown segments of the Los Angeles River revitalization master plan, envisioned by Gruen AssociatesWSP, CH2M, Chee Salette, Mia Lehrer + Associates, AECOM, and Tetra Tech. The project, known as the LA River Downtown Design Dialogue, asked designers to create potential schemes for development of the Downtown Corridor that “focus on interventions to improve connectivity and access to the river” and “imagine how to achieve function while embracing bold, world-class design,” while integrating in river adjacent projects currently in development, such as BIG’s 670 Mesquite.
