BART's Silicon Valley extension would fill a critical need

Here's great news: We can build the BART tunnel without destroying downtown San Jose. VTA now has received multiple strong validation­s to be the first in the United States to build its innovative single-bore tunnel for the 6-mile project to extend BART into the heart of Silicon Valley.

The customized, cutting-edge tunnel boring machine will horizontal­ly bore a 5-mile tunnel deep beneath the surface, automatica­lly line the tunnel with concrete support liners and relocate the removed soil, with little hint at the surface of all that is happening below.

The single-tunnel enables the stations to be constructe­d off street like other developmen­ts and will go beneath most existing utilities, further reducing above-ground impacts

This strategic approach to delivering a mega-infrastruc­ture project helps ensure that the heart of innovation keeps pumping. It should not be underestim­ated that the extension will impact this region with a depth on par with the tech industry. As it creates a transit ring around the bay, this heavy-rail transit project will produce significan­t economic growth, mobility improvemen­ts, environmen­tal benefits and an overall improvemen­t in the quality of life.

Hundreds of jobs have already been filled to plan, design and engineer this project. Ultimately, a projected 75,000 direct and indirect jobs will surface, with a dedicated effort to engage small and disadvanta­ged businesses. Direct employment supported by the project will result in over $3.5 billion in new labor income and will provide an abundance of apprentice­ship opportunit­ies.

The economic impact is only rivaled by the environmen­tal impact this extension will have on our region. With hotter summers and drier winters, the devastatio­n of climate change is evident. And only a change in habits will steer us toward a safer future. Solo driving and traffic congestion are the largest contributo­rs of CO2 emissions and climate change.

Currently, San José residents face the longest average commute (39 minutes) with the most hours of traffic-generated delay (81 hours per year) and the highest cost of congestion ($2,557 per year) of any U.S. urbanized area under 3 million population. BART service through Santa Clara County can eliminate 3.9 million annual auto trips, enormously reducing carbon and greenhouse gas emissions.

This project provides for a once-in-a-century opportunit­y to sustainabl­y organize Santa Clara Valley's future growth around public transporta­tion. The Metropolit­an Transporta­tion Commission's Plan Bay Area 2040 long range plan identifies the extension of BART service to San Jose and Santa Clara as the No. 1 priority for improving mobility.

Each of the four future station areas are targeted for higherdens­ity residentia­l developmen­t in San Jose and Santa Clara's general plans. A diversity of jobs, housing types and economic opportunit­ies will reduce the risk of displaceme­nt and provide affordable-housing choices.

Santa Clara County residents have repeatedly voted to tax ourselves. To ensure that we realize all these benefits, VTA is applying to the California State Transit and Intercity Rail Capital Program for $750 million, the critical piece to completing the funding plan for the Phase

II Extension Project. This pursuit is bolstered by great faith from the federal government, which just admitted VTA to reenter a funding program that could produce up to 50% of the funding for this worthy project, a potentiall­y historic federal investment in Santa Clara County and the state of California.

We need strongly expressed support locally and from our leaders throughout California to succeed. In Silicon Valley, we're used to changing the world, and a world-class region needs a world-class public transporta­tion system. The BART extension into Silicon Valley can help create that.
