Improve flood facility operations and maintenance.

Back to: Reduce flood risk and improve resiliency.

Action: Improve flood facility operations and maintenance.

Dams, levees, channels, and other flood management projects, like all infrastructure, require proper operations and maintenance. Increased investment in operations and maintenance of LA River infrastructure can increase its effectiveness and lengthen its useful life, providing a greater return on initial capital outlays.

Methods

specific, tangible ways to reach the goal

Expand coordination between responsible flood management agencies including the US Army Corps of Engineers and the LA County Flood Control District and consolidate responsibilities under the LA County Flood Control District Flood Control District through divestiture or deauthorization to streamline operations and maintenance, facility management, funding, and permitting.
Manage sediment and invasive vegetation in the river channel using best management practices.
Related Actions/Methods
Increase capacity of the river in high risk areas to provide flood risk reduction to at least the 1% (100-year) annual chance flood event or to a level recommended by a risk assessment.

Reduce peak flood flows into the river.

Increase plant species biodiversity, and focus on the use of local California native plants in and around the river corridor.
Implement new technologies such as real-time monitoring, reporting, and controls.
Update the flood risk and pumping plant telemetry systems.
Update and improve the mapping of the watershed’s storm drains, channels, access, and jurisdictional ownership.
Continue to implement, review, and improve dam and levee safety programs that ensure the flood management infrastructure delivers intended benefits while reducing risks to people, property, and the environment through continuous assessment, communication, and management.
