As we approach 2018, Phase II of VTA’s BART Silicon Valley Extension is gaining steam. VTA and BART are making key decisions about Phase II – the next six miles of BART into downtown San Jose and the City of Santa Clara.
There are multiple factors and extensive analysis being taken into consideration to decide the best way to deliver the project.
The state and federal environmental review process is nearing the end but not before a final project description is approved by VTA’s Board of Directors. To accomplish this, VTA held public workshops in August and September for the Board and a joint meeting with the BART Board of Directors to provide an overview of Phase II’s environmental review process, the location options for Downtown and Diridon Stations, and single-bore and twin-bore tunneling methodologies. A peer review of the tunneling methodologies is being conducted through Fall 2017.
The VTA Board is expected to make a final decision on the project description (type of tunnel and station locations) and certify the final environmental document at its first meeting in 2018. By March 2018, VTA anticipates securing project approval from the federal government allowing VTA to move forward with engineering and pre-construction activities for the project.
While VTA will design and build Phase II, BART will ultimately operate and maintain the system once it opens, as will be done with the Phase I Berryessa Extension. Over the course of the decision timeline, VTA will continue to work with BART and the community to develop a project that will deliver the economic and environmental benefits expected from fully extending the BART system into downtown San Jose and the City of Santa Clara.
