Los Angeles County Releases the Public Review Draft of  the LA River Master Plan

Los Angeles, CA – Today, January 13, 2021, LA County released the public review draft of the LA River Master Plan encompassing the 51-mile river. The LA River Master Plan is a goal-driven plan that combines community input with geospatial needs analyses to form the foundation of the Master Plan and supports a 25-year vision for the LA River and its associated communities. The goals cover reducing flood risk; creating parks and healthy, connected ecosystems; increasing equitable access to the river; addressing housing affordability, displacement, and homelessness; enhancing arts and culture; increasing education and engagement; developing a more suitable local water supply; and promoting safe, clean water.

As the prime consultant and lead engineer working for LA County Public Works, Geosyntec leads a team of experts and is responsible for program management and the engineering and technical components of the Master Plan. These components include hydrology and hydraulics analyses, water quality and water supply, climate change, infrastructure, and brownfields redevelopment. Significant analyses focused on hydrology and hydraulics increasing project proponents' understanding to develop projects that will work within, and potentially enhance, the flood management system. Key consulting partners include OLIN for landscape architecture, urban design, and planning; Gehry Partners for architecture and planning; River LA and Urban Semillas' Miguel Luna for community engagement; Street Level Advisors for affordable housing; Kris Helm Consulting for water resources; Kearns & West for Steering Committee facilitation, and Mercury for media relations.

The LA River Master Plan builds on the work of over 140 other planning documents and identifies community-based needs along with project opportunity sites to meet those needs. It serves as a toolkit for community-driven projects along the river to achieve regional resiliency, sustainability, and equity objectives. The Master Plan will greatly improve funding opportunities for river adjacent projects. The Master Plan provides strategic directions to improve housing stability, increase park space, and improve access to cultural resources, among others, and local and state funding is already helping to advance these initiatives in the lower river where some of the region's needs are the greatest.

The Master Plan was developed over a three-year period with significant community input from a 41-member Steering Committee, 13 community meetings up and down the river, a first-ever LA River focused youth summit, and a community partner program that helped the County and consultant team engage with thousands of county residents in person and nearly one million impressions online.
