SB 743: Modernizing Transportation Analysis

What is SB 743?

In 2013, the State of California passed Senate Bill 743 (SB 743), which alters how transportation impacts from new development are measured under the California Environmental Quality Act (CEQA). 

Why do we have to do it?

We are required to align transportation analysis with State law. Traditionally, transportation impacts have been assessed in terms of Level of Service (LOS), a measure of automobile delays along a roadway. SB 743 requires shifting from LOS to metrics aligned with state goals around greenhouse gas reduction, land use diversity, and development of multi-modal travel networks. 

What do we have to do? 

The Governor's Office of Planning and Research (OPR) has determined the best metric to support State goals is Vehicle Miles Traveled, or VMT. Cities and counties can no longer use LOS to determine significance of transportation impacts under CEQA as part of the environmental review of a project and are required to establish thresholds of significance in VMT. The City of Mountain View expects to have new VMT thresholds adopted by July 1, 2020.
