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.
