Upcoming Planning Commission Study Session

The Planning Commission will be having a study session on proposed changes to the City’s transportation analysis methodology and processes to comply with state law (Senate Bill 743). City staff will have a presentation that: (1) highlights the provisions of Senate Bill 743, (2) discusses Santa Clara’s current methodology for analyzing CEQA transportation impacts (i.e. Level of Service), (3) introduces the concept of Vehicle Miles Traveled (VMT), (4) provides information about what other California cities are doing to comply with Senate Bill 743, and (5) discusses the City’s workplan to update Santa Clara’s transportation methodology changes. The study session is scheduled for December 11, 2019 at the Santa Clara City Hall Council Chambers at 6 p.m. and the public is welcome to attend.

Past Community Meetings

On October 24 and December 30, 2019, the City hosted two community meetings to introduce Senate Bill 743 and Vehicle Miles Traveled (VMT). The presentation introduced Senate Bill 743 and the reasons why California cities should adopt VMT as the measure of transportation environmental impacts. The City is planning on hosting a second set of community meetings in spring 2020 to provide more information on proposed updates to the City’s transportation analysis policy.

Recent City Council Study Session Summary

On November 5, a City Council study session was held to provide the Council and general public information about the proposed changes to the City’s transportation analysis methodology and processes to comply with state law (Senate Bill 743). Public Works staff presented information on the State’s requirements and the technical considerations that staff will be evaluating as well as a schedule for adoption. Issues raised by the Council included concerns about regional traffic, countywide coordination, the use of big data, any proposed DMV fees for VMT, what other cities have done, how the City’s travel demand model measures VMT, the importance of continued use of level of service (LOS) and methods for estimating VMT.

The City of Santa Clara is changing the way we measure how new development impacts transportation to comply with State law by updating our transportation analysis methodology and processes. This website will be updated with information on an ongoing basis as we develop this new transportation policy, including details on community outreach and public hearings.



In 2013, the State of California signed Senate Bill (SB) 743 into law, which mandates that cities can no longer use automobile delay, commonly measured by Level of Service (LOS), in transportation analysis under the California Environmental Quality Act (CEQA). The State has issued guidelines that recommend adopting Vehicle Miles Traveled (VMT) as the methodology to determine whether a project has transportation impacts under CEQA.


The State requires all Cities to adopt this new transportation analysis methodology by July 1, 2020. However, the City will continue to evaluate transportation impacts using Level of Service until a new policy is adopted. The following depicts the City's timeline for developing a new transportation policy.VMT Timeline

Community Outreach

To ensure that citizens and stakeholders are informed about this change in the way the City measures transportation impacts, we will be conducting various community outreach activities in the coming months. New and upcoming outreach activities will be posted at the top of this page as they are scheduled. Once the outreach has occurred, information and meeting materials will be posted below.
