PROJECT SUMMARY
Located at the confluence of Bell Creek and Arroyo Calabasas, Canoga Park presents a significant opportunity to reimagine the Los Angeles River as a shared cultural, ecological, and infrastructural resource for adjacent communities in relation to the goals of the updated LA River Master Plan, adopted by the LA County Board of Supervisors on June 14, 2022. The area faces hydraulic challenges related to flood risk reduction, as the channel is only estimated to have flood conveyance capacity for a 2% (50 year) event, significant issues with water quality, and a critical lack of parks and open space. Canoga Park is identified as a Major Project Zone in the Master Plan and was commissioned to explore large scale feasibility for project development across the study area.

The Headwaters Area Project Concept Report is now
live!
The Headwaters Area, comprised of three zones along an
approximately one mile stretch of the LA River in the
West San Fernando Valley, City of Los Angeles, is
identified as a Major Project Zone in the LA River
Master Plan. The concept phase is comprised of three
parallel threads; engagement, data driven needs, and
technical feasibility. The Headwaters Area Project
Concept team has been focused on braiding these
threads together in order to synthesize what is
desired, what is needed, and what is possible into
project opportunities at the Headwaters Area. This
report responds to the hydraulic challenges regarding
the current estimated flood conveyance capacity, as
well as very high water quality and parks and open
space needs in the surrounding communities.
