Facts about Purple Line Extension construction in Beverly Hills

Some Beverly Hills students staged a walkout today to protest Purple Line Extension tunneling under Beverly Hills High School. The project is being built in three sections and will ultimately extend the subway nine miles from Wilshire/Western to Westwood to serve the region’s second-largest job center and a part of town notorious for its traffic congestion.

Here are some facts about construction:

•Metro consulted with leading experts and specialists in engineering, geology, seismology, tunneling and construction as part of a thorough, five-year environmental review of the Purple Line project. This was followed by a supplemental environmental report that addressed issues specific to the high school. The findings further confirmed our methodology and continued commitment to safety. To that end, Metro is implementing a number of mitigation measures to minimize impacts to the high school during construction.

•Metro is mitigating dust by implementing control measures including covering loads, sweeping and watering as required by and in consultation with South Coast Air Quality Management District (SCAQMD) regulations.

•Gas monitoring wells will be monitored before, during and after tunneling. Wells and ambient air will be monitored throughout construction. In addition, to using special earth-pressure balanced Tunnel Boring Machines, within the tunnels we will be using:

–Double gaskets (seals) on the tunnel liners.
–Gas detection system with alarms.
–Emergency ventilation.
–Automatic equipment shutoff system.

•Metro will adhere to noise requirements from both the City of L.A. and City of Beverly Hills. We will closely monitor noise levels to ensure the project is abiding by agreed-upon noise restrictions.

•Hauling of excavated soil to and from the site is restricted during peak hours, 7am to 9am and 3:30 p.m. to 6 p.m., Monday through Friday. As a result, it is anticipated that most hauling trips of excavated soils will occur in the evening and overnight hours when students are not at school. The truck loading area is over 100 feet from Beverly Hills High School.

•Based on historical records, research and further investigation, no oil wells are presently known to exist along the tunnel alignment. In an abundance of caution, Metro will use Magnetic Sensing Methods to look for any unmapped wells. If any are discovered, Metro will cease tunneling until they are addressed in accordance with State regulations.

•The Health Risk Assessment predicted that the cancer risk due to emissions generated from construction of the project did not exceed the existing SCAQMD cancer risk threshold of 10 in a million.

•Based on a thorough analysis of multiple station locations and alignments, the selected alignment provides the greatest benefits and fewest impacts.  A station on Santa Monica Boulevard is not feasible due to the presence of the Santa Monica fault.

•Since 2015, Metro has been working closely with the City of Beverly Hills on construction mitigation measures specific to work within the City. This partnership has resulted in a Memorandum of Agreement (MOA) that identifies mitigation measures for the city as a whole and specifically for Beverly Hills High School, including:

–Special noise limits for work near Beverly Hills High School.
–Limits on construction activities during school hours.
–Use of an Independent Compliance Monitor (ICM) to ensure project compliance with the MOA.
–The installation of air filters on portable classrooms at Beverly Hills High School.

Section 2 of the Purple Line Extension project includes 2.59 miles of additional tracks and two new stations at Wilshire/Rodeo and Century City/Constellation. The project received full Federal funding from the U.S. Department of Transportation in January 2017. Since 2016, Metro has been working on advanced utility relocation without incident, making way for major project construction to start this fall. Section 2 is anticipated for completion in 2025. Please see the Purple Line Extension’s home page for more information on all aspects of the project.

    • Right! They don’t understand that they are getting help with transportation. They truly are wasting their time. I bet they don’t even know why they’re protesting. Stay in school kids.

  1. I wish the Beverly Hills School District would use its money to better pay its teachers rather than its lawyers to continue fighting this losing battle over the Purple Line.

    • It is not just the district. The students themselves and the parents are the ones that want the line re-routed.

      Would you send your kids to school in a construction zone?!?!?

      • They don’t want it re-routed, they want it killed.

        Sending kids to rail construction zone? This has been done for the Gold Line at an at-grate next to a couple of schools with no problem. Look at the Expo Line and Dorsey HS? Are you telling us that the BH HS students are that dumb they need mommy and daddy to walk them to/from school? Hit and run drivers seem to be the norm now. The subway will not be at-grade and should take some cars off the road.

      • The High School is in the middle of a master plan that involves building a new gym with a three-story underground parking garage underneath, tearing down the old gym, and building a new track and outdoor swimming pool. Why is a truck loading zone 100 feet off campus intolerable and cause for a protest, while excavating an underground parking garage in the middle of campus is just great?

        The school sure seems to be done a ton of construction themselves for people who say any construction is unacceptable.

  2. All over los Angeles subways and light rails are operating threw public schools. Know it’s going threw rich kids schools and its a big deal please continue the purple line and finish it

  3. Sorry spoiled rich kids and their parents, but the subway is needed and long overdue. Some of us regular people would like to see LA have real public transportation system in the city. Look at the bright side, once the subway is done the roads might be less crowded so you can drive your luxury vehicles with much more ease than before. They can walkout all they want. I am sure their private tutors can cover what they missed in class.

  4. I heard they had to ride smelly diesel buses to their protest. If they had just waited a few years, they could have taken the train.

  5. *rolls eyes* didn’t the study done by an independent firm commissioned by BHUSD itself find that the alignment under the school is the safest and least costly? You’d think that’d be enough of an embarrassment. Holly blown-jebus! Give up already!
