Los Angeles River Active and Upcoming Projects

Published July 10, 2017

Levee Wall Repairs

The Corps awarded a contract for like-for-like repair of damaged embankment and levee toe within the Glendale Narrows section of the Los Angeles River Flood Control Channel at Reach 4D. In order to conduct the repair, a limited portion of the channel will be dewatered. Approximately 3,000 square feet of vegetation and sediment will be removed to facilitate the dewatering process. A temporary access ramp into the channel will also be installed. Work began in the summer of 2017. The Corps is anticipating that the construction period will last approximately 5 months.

Non-Native Vegetation Management Project

The Corps has awarded a contract to BJD Services through a competitive bid process to treat non-native vegetation and remove large pieces of concrete debris from reaches 2A, 5C, 6A, and 6B of the Glendale Narrows section of the Los Angeles River Flood Control Channel.  Any identified non-native invasive vegetation species within these areas will be treated, but the Corps is specifically targeting giant reed, castor bean, and palms.  Non-native invasive vegetation treatment will consist of hand cutting the non-native invasive species followed by hand application of herbicide.  Herbicide will be applied by applicators certified by the State of California in a manner consistent with the products' labeling.  Only herbicides approved for use in aquatic environments by the U.S. EPA and California Department of Pesticide Regulation will be used.  Native vegetation will be avoided.  All active bird nests will be avoided.  Initial removal of invasive species will occur during the non-nesting season; follow up treatments will occur on a monthly basis year round.  Biological monitors will be used.

HESCO Barriers

HESCO barriers are a proactive flood protection measure put into place to mitigate for flood risk brought to attention by the predicted 2015/2016 El Nino storm season.  The Hesco barriers were strategically placed to protect areas adjacent to portions of the Glendale Narrows section of the Los Angeles River at greatest risk of flood waters overtopping the levee walls.   After the flood season was over, the Corps worked to quickly remove a portion of the HESCO barriers most significantly affecting recreation along the Los Angeles River Flood Control Channel.  Due to the reduced ability of the channel to contain flood waters and the limited funding available to the Corps to remove and replace the HESCO barriers, portions of the originally installed barrier will remain in place as a public safety measure for the time being.
