USACE Awards Contract for Los Angeles River Barrier Installation

The USACE awarded a $1.3 million contract to JF Engineering on January 9 to install roughly 3 miles of temporary protective barriers to increase bank height along the most vulnerable reaches of the LA River that will restore channel capacity and reduce the risk of flooding to homes and businesses.

The Corps conducted a review of existing conditions of the flood risk management systems it oversees.

In total, 11 dams, one debris basin and more than 50 miles of channel within the Southern California region were evaluated for this storm season.

The review resulted in interim risk reduction measures to establish a consistent flow rate, or conveyance capacity, along Corps operated and maintained reaches of the Los Angeles River.

The Corps has identified measures for channelized areas along the Los Angeles River from approximately Griffith Park to Elysian Valley, including the Glendale Narrows area, which pose the greatest risk of flooding to adjacent communities during large storm events.

A combination of factors, including design capacity and the presence of vegetation growth and sediment accumulation, contributes to reduced water flow in these areas.

The work on the project will start this week.
