LOS ANGELES -- The Corps will begin removal in early May of some of the temporary protective barriers that were placed along the most vulnerable reaches of the Los Angeles River. These barriers were placed as an interim risk reduction measure due to the reduced capacity in these sections from accumulated sediment and vegetation.
Initial focus will be to strategically restore access for cyclists, equestrians and pedestrians.
On the west bank of the river, all temporary protective barrier will be removed from the bike path from just north of Los Feliz Boulevard to just north of Hyperion Avenue.
Access will be opened up on the east bank of the river at the equestrian crossing near Verdant Street, the pedestrian bridge at Sunnynook Drive, and at a point south of Dover Street.
"As capacity is restored in the channel from our operations and maintenance activities, we will continue to remove additional temporary barriers," said David Van Dorpe, Los Angeles District deputy for programs and project management. "We're moving forward deliberately to ensure we can restore as much public access as possible."
The Corps will continue to evaluate alternative courses of action to address flood risk during the summer months in anticipation of next storm season.
Removal work is anticipated to take several weeks. Crews will be working six days a week to strategically remove barriers safely and expediently.
Once barrier is removed from the bike path, LADOT will evaluate the pathway before reopening it to cyclists.
