SB 743: Changing How We Analyze Traffic Impacts 

To sign up for e-mail updates on this effort, please click here.

With the adoption of Senate Bill (SB) 743, the State of California has changed the method of traffic analysis required through the California Environmental Quality Act (CEQA) for publicly- and privately-initiated projects.  The law will change the way local jurisdictions, like the County of San Diego (County), analyze transportation impacts from development projects, and identify mitigation measures to reduce those impacts. SB 743 becomes effective on July 1, 2020.

The current practice of evaluating traffic transportation impacts uses on road congestion or level of service (LOS).  SB 743 will require the amount of driving and length of trips – as measured by "vehicle miles traveled" or VMT – be used to assess transportation impacts on the environment for CEQA review. These impacts will be reduced or “mitigated” by options such as increasing transit, providing for active transportation such as walking and biking, and participating in mitigation banks.

All jurisdictions have the option to tailor requirements to their unique communities. The County is developing alternatives to present to the Board of Supervisors (Board) on how to implement SB 743.
