#ElNiñoLA Update: LA River Bike/Ped Path Temporary Closure

On Friday, January 8, 2016 Mayor Eric Garcetti and Los Angeles District Commander Col. Kirk Gibbs announced that the U.S. Army Corps of Engineers (USACE) will be taking new interim measures to improve flood protection on the Los Angeles River during #ElNiñoLA.

The USACE is the federal agency responsible for navigable bodies of water, including our very own Los Angeles River. The LA River has an almost century-long history with the USACE that started after a series of floods, including the 1914 flood which caused $10 million in damages. A public outcry for action to address the recurring flooding problems led to the formation of the Los Angeles County Flood Control District. Early flood control efforts included some channelization and the need for reservoirs. Bonds were approved by taxpayers in 1917 and 1924 to build major dams. After two additional destructive floods in the 1930s, Federal assistance was requested and the Army Corps of Engineers took a lead role in channelizing the River. Channelization began in 1938. By 1960, the project was completed to form the fifty-one mile engineered waterway we are familiar with today.

Due to the expectations of a powerful El Niño season, USACE recently received emergency federal funding to put in place safety measures for the area of the river that spans from Griffith Park to Elysian Valley.

“Our river is unique — most of the year it runs nearly dry, and then during the rainy season it runs in powerful torrents as we’ve seen this week,” said Mayor Garcetti. “My top priority during El Niño is to ensure the safety of everyone in our city, and I thank the Army Corps of Engineers for taking action now to enhance the river’s flood management functions.”

The Los Angeles District of USACE determined this area needed increased capacity to keep the river in its banks. The L.A. District declared an emergency to USACE headquarters on January 6, prompting headquarters to provide $3.1 million in federal funding and nearly 3-miles of temporary barriers, known as HESCO Bastion. The temporary barriers act as industrial size sandbags, effectively raising the sides of the river channel and temporarily increasing its capacity during the winter storm rains.  The District also received approximately $500,000 to begin removing water-flow impeding vegetation from the highest-risk areas within the channel, in an area just upstream and downstream of Riverside Drive and the Zoo Bridge.

Industrial size sandbags were mobilized from Nebraska to LA a few days ago in preparation for the expected storms

Anytime rain is in the forecast the LA River Bike Path is closed for safety (shelters and resources are available for people experiencing homelessness). In the coming months, the raised barriers will allow for the expected volumes and help protect against flooding in adjacent neighborhoods. The barrier will be under construction on the bike path beginning Tuesday, January 19, 2016.

Due to the configuration of the HESCO barriers on the bike path by the U.S. Army Corps of Engineers, the LA River Bike Path will remain closed through #ElNiñoLA season from Zoo Drive to Glendale Blvd (with the Alex Baum Bridge remaining open as a bicycle and pedestrian crossing across the LA River and 5 freeway).  North of this location, in the Griffith Park section of the Path, there is also an unrelated intermittent closure due to Caltrans freeway bridge rehabilitation work. Check out the City’s Detour Guide for getting around temporary closures on the LA River bike/ped path here.

UPDATE: As many of you may already know, the Bike Path has been closed due to flood control measures installed by the Los Angeles District, U.S. Army Corps of Engineers since January 2016. At this juncture, our agencies anticipate the earliest the Bike Path may reopen, post-‪#‎ElNiñoLA‬ flood risk and weather permitting, will be Memorial Day weekend.

Stay tuned for updates about construction and planned detour routes. Information will be available via our Blog (where you can also find articles about how to bike through El Nino and more!) and social media channels (@ladotbikeprog) using the hashtag #ElNiñoLA.

Updated 3/16/2016: Current information on U.S. Army Corps of Engineers’ barrier configuration added.

Two of Three Missing Alex Baum Bridge Plaques Recovered

In early March, the bronze plaques which were installed to honor Alex Baum, were stolen from the Alex Baum Bridge. We just received news that two of the three plaques have been recovered!

Here’s a little history about the man, the legend… The bronze plaques were installed to call attention to Alex Baum’s accomplishments and legacy in supporting bicycling as a mode of transportation and recreation throughout his lifetime. The first pair of bronze plaques were installed at the inauguration of the Baum Bicycle Bridge in 2002. Fast forward to 2012, and as part of a re-dedication of the Baum Bicycle Bridge on its 10th anniversary, the second pair of bronze plaques with biographical information about Mr. Baum were added.

Just around the time City of LA’s longest serving bicycle-advocate Alex Baum (1922-2015) passed away on Sunday, March 1st, the three bronze plaques were reported missing. As you can imagine, our team was saddened to hear the news. A few days after the bronze plaques were stolen, South Coast Recycling contacted the Los Angeles Police Department (LAPD) to report that someone had tried to sell these bronze plaques to their facility. Luckily, the Center was able to recover two out of the three stolen bronze plaques. A third bronze plaque (like the one in the photo below) is still missing. LADP continues to search for the missing plaque. Anyone with information should contact LAPD.

LADOT staff is currently in the process of installing the two bronze plaques returned to us by our friends at the LA Recycling Center.

Thank you for your support,
