The Purple Line Extension held a meeting with the Phase 1 advisory group last week. The Powerpoint presentation given by Metro is posted above with a ton of information on ongoing utility relocations, future construction activity and mitigation plans to keep noise at a minimum, as much as is possible, for those who live and work near the future subway [pdf here].
I’ve also pulled a few key slides to show below (but please see the entire presentation!!!). In particular, I know several readers asked for a construction timeline after Metro and the Federal Transit Administration last month signed a deal providing $2.1 billion in federal grants and loans to help fund the building of the project’s first phase, which is also funded by the half-cent Measure R sales tax increase approved by L.A. County voters in 2008.
The first phase of the Purple Line Extension will run for 3.9 miles between the existing Wilshire/Western station and Wilshire/La Cienega. There will be three new stations at Wilshire/La Brea, Wilshire/Fairfax and Wilshire/La Cienega. The project’s second and third phases will extend the Purple Line to downtown Beverly Hills, Century City, Westwood and the VA Hospital.
The following slides describe the basic construction activities that will be taking place over the next nine years.
There are also 10 slides on noise mitigation strategies. A couple of the key ones are below — but I highly encourage you to look at the entire presentation above for more info about this topic. Metro officials have emphasized to me time and again that while they are seeking extended work hours to get the project open in 2023, they are committed to keeping as much noise as is possible to a minimum, performing the most noisy tasks during the day or early evening and being respectful of surrounding neighborhoods.
Metro officials really want people to understand that a lot of the construction activity will be occurring below street level and out of view. The most disruptive activity is that which happens at street level — at the new station locations and Wilshire/Western where Metro has to open the ground to retrieve the tunnel boring machine and the extension must be connected to the existing Purple Line tracks. Those activities will be restricted by time and location.
As we’ve stated previously, Metro is seeking extended work hours in order to wrap up the surface work as quickly as can be done and then most of the station construction will occur below ground, beneath concrete decking.
