Project: Feasibility Study: Sepulveda Basin Project

Description: The goal of the Project is to study the feasibility of revitalizing the Los Angeles River within the Sepulveda Basin toward a healthier and more functional ecosystem by investigating: 1) removing concrete and other modifications; 2) increasing regenerative wetland and riparian habitat functions and values; 3) using geomorphic and bioengineering design principles to restore geomorphic and ecosystem functionality to the River and riparian corridor within the Sepulveda Basin; 4) adding capacity for stormwater detention to reduce downstream flood hazards and increase potential for groundwater recharge; 5) improving the recreational interface with the River and its tributaries, which will enhance access and could expand the existing RRZ.

Reference Number: 3810P012003

Implemented By: The River Project

Objective: Funding for project planning and design for the Los Angeles River that flows through SepulvedaBasin.The 2,000-acre basin serves as a significantflood management area, detaining and infiltrating stormwater that would otherwise flood downstream communities. The Sepulveda Basin provides many uses and amenities, including City of Los Angeles active recreational parks, a water treatment plant, open space habitat with trails and creeks, and the River Recreation Zone. The mainstem Los Angeles River within the basin is a semi-natural stream, with three distinct segments, including a concrete channel, a natural channel bottom with concrete upper banks, and a natural channel bottom with rip rap banks. In the natural channel reaches, the channel exhibits limited geomorphic functionality with riparian habitat appropriate to that level of functionality. Within the concrete channel, there is no geomorphic functionality.
