In 2015, the Los Angeles County Metropolitan Transportation Authority (Metro) selected KOA to prepare a feasibility study for a bikeway along an 8-mile segment of the Los Angeles River channel near downtown Los Angeles and the City of Vernon. This segment runs between the confluence of the Arroyo Seco near the 110 Freeway Bridge and Atlantic Boulevard and, due to confined rights-of-way and vertical channel walls, represents a formidable barrier to a future bikeway that will eventually run alongside the entire 52-mile extent of the river. Alternatives analyzed included the routes along the channel bottom, mounted on the channel walls, on aerial structures, and on adjacent roadways. Due to the inaccessibility of some of the project sites, aerial drone photography was included in the field work. Analysis included hydraulic feasibility, environmental impacts, and connectivity to the non-motorized transportation network.
