In its most recent edition, the Beverly Hills Courier published incorrect information about construction impacts of building the Westside/Purple Line Extension:
The Metro tunnels are not an issue for Beverly High only. Just this past week, neighbors of the proposed La Cienega and Wilshire station – touted by Mayor Willie Brien as being “without controversy” – are now learning that their very existence is threatened by the massive excavation planned by Metro at that location. According to Metro, an open trench nearly 2,000 feet or more long and nearly 100 feet wide will take all of Wilshire for up to seven years. Plus, the big dirt haulers 24/7 in and out. How will our signature “Restaurant Row” fare? How will the adjacent medical buildings fare? How will the historic Fox Wilshire – now the Saban Theater – survive? Metro told these people there would be no open ditch, no damage to foundations – that it will all be just fine. That is not true, as they are now learning.
The correct information:
•Station boxes and excavations for the Subway Extension will each be about 1,000 feet long by 70 feet wide, not 2,000 feet long and nearly 100 feet wide as wrongly reported by the Courier.
•There is certainly a lot of dirt that will have to be hauled from the stations but there is no plan to haul dirt from the station excavations 24/7, as the Courier wrongly reported.
•The stations for the existing Red and Purple Lines were not built with trenches that were open for the duration of construction and there is no plan to build stations for the new line with permanently open trenches, as the Courier also wrongly reported.
•There will be temporary street closures for the current subway project during initial station excavation. The excavated area will then be covered by concrete decking that will allow traffic to flow on the streets above the station, while construction work continues below ground. When the decking is removed at the end of construction, there will again be temporary street closures.
•Street closures, truck haul routes and times, work hours and the like are subject to the approval of the city where there work is located. Construction mitigations will be guided by the Mitigation Monitoring and Reporting Plan that was adopted as a part of the Final Environmental Impact Statement/Report.
•And here is previously published construction information from a Metro FAQ that elaborates on some of this:
23. Will traffic on Wilshire Boulevard and other major streets be disrupted?
There is no way to build the subway without some impact to traffic. Traffic impacts will mostly be concentrated at station areas and occur primarily at the beginning and end of station construction. In these areas, detours and temporary lane closures will be required for initial station excavation and to install the temporary street decking. These same measures will be required toward the end of station construction to remove the decking and reconstruct the street. In the approximately five years in between, while the station is being constructed under the decking, impact to surface street traffic will largely be limited to trucks hauling construction materials and excavated soil on designated haul routes. Between stations, tunneling will have little if any impact to surface traffic. Please see our Construction Fact Sheet for more information.
Below is the entire fact sheet, complete with drawings that show how station construction work will be done.
