Abstract

The concrete channel of the Los Angeles (LA) River is probably one of the most recognizable rivers in the world. Channelized to manage the risk of flooding as the Los Angeles region urbanized, the river today is an architectural and engineering feat in the eyes of some people but an ecological disaster to others. The river flows adjacent to 17 cities and among some of the most environmentally burdened, park poor, and underserved communities of LA County. With over 2,300 acres of largely publicly owned land within the river right-of-way, a reimagined LA River can impact the lives of the one million people that live within a mile of the river.

The LA River Master Plan, led by Los Angeles County and scheduled to be completed in fall 2021, proposes 51 miles of connected public open space with multi-benefit projects supporting nine goals ranging from flood resilience to housing affordability, to ecological function, and to arts, education, and culture. The data-based plan for the next 25 years includes a watershed-wide research effort to document and understand water quality, water conservation, and flood risk in relation to environmental and social issues. The plan includes traditional and innovative strategies within a “kit of parts,” interventions that include over 65 components ranging from habitat bridges to dry arroyo side channels demonstrating opportunities for enhancing ecosystem services to create a thriving urban habitat and connected network of parks along the river.
