Envision Silicon Valley Project Evaluation

Long-Range Transportation Goals

VTA staff identified three outcomes for the Envision Silicon Valley process, a community engagement effort that led to 2016 Measure B: 

  1. Develop criteria that will be used to create a viable list of transportation projects.
  2. Establish a list of transportation projects to address mobility and congestion.
  3. Create a financing plan.

The VTA Board of Directors adopted the Goals for Envision Silicon Valley on June 4, 2015. They were developed in collaboration with the Stakeholders Committee and were previously reviewed and recommended for adoption by the Ad Hoc Committee on Envision Silicon Valley. Stakeholders also developed 32 quantitative and qualitative Evaluation Criteria to evaluate how projects would help achieve the goals. The VTA Board of Directors approved the criteria in September 2015.

In the first quarter of 2016, VTA staff evaluated projects of $100 million or more. To provide a more meaningful analysis, similar projects, such as bike and pedestrian projects, were also grouped together and analyzed if they equaled $100 million or more.

For further details, view the Project Evaluation and download the Envision Silicon Valley project list adopted by the VTA Board of Directors.


Below are the preliminary results of the Envision Silicon Valley Project Evaluation. This preliminary project evaluation may be updated as the results are further analyzed.

Projects submitted as part of VTA's 2015 Call for Projects were grouped by size, location and type to help maximize the effectiveness of the analysis. See below for a summary of how the projects were grouped.

Projects that weren’t modeled are still eligible to be placed on a potential sales tax measure. However, we will not have the benefit of the analysis to help us with our deliberations. Click here for the list of projects that weren’t analyzed.

Each project or group of projects was analyzed based on Evaluation Criteria designed to measure how well the project meets the goals for the Envision Silicon Valley program, as adopted by the VTA Board of Directors. The analysis will help community members, stakeholders and policy makers in their deliberations regarding which projects should be considered for a ballot measure.

The Project Evaluation is but one tool to help everyone in their deliberations regarding which projects should move forward for a potential sales tax measure. There are other factors, including geographical balance, project variety, public input and polling results that should also be considered in formulating the draft plan.​

Call for Projects

The projects included in this evaluation are the result of a Call for Projects that VTA conducted in 2015. VTA worked with city agencies, the County, civic groups, stakeholders and the public to develop a list of new and updated projects to be included in Envision Silicon Valley and Plan Bay Area 2040. The VTA Board of Directors adopted this comprehensive list.​

Project Grouping

With such a large submission of potential projects as well a large number of evaluation criteria, staff worked with the stakeholders, advisory committees and the Board Ad-hoc Committee to group the projects in the following manner:
  1. Projects contained in the current Valley Transportation Plan were not included in the analysis as they already have funding sources identified. The exceptions included projects that have a funding shortfall and/or may be considered for funding through a future sales tax. These included: BART Phase II, the Eastridge Light Rail Extension, and the Vasona Light Rail Extension.
  2. Projects that did not have sufficient projects descriptions, cost estimates, and/or a public agency sponsor were not analyzed.
  3. Projects were grouped by program or by corridor. For instance the Caltrain Grade Separations were grouped as a program and highway projects were grouped by corridor. This allowed us to see the full benefits of these projects by modeling them as a group.
  4. Only projects or programs with an estimated cost of $100 million or more were analyzed. Projects with costs of less than $100 million are generally smaller in nature and very difficult to model; however, smaller projects may have been included within a program (for example highway corridors and expressway tiers).
