California Senate Bill 743
What is California SB 743?
Senate Bill 743 (SB 743) shifts California’s approach to transportation impact analysis. Instead of focusing on congestion relief, it places the reduction of vehicle miles traveled (VMT) at the center of impact analysis.
SB 743 transforms how engineers and planners approach transportation and land use plans and projects.
As the law evolves, we evolve our methods. This shift gives communities the chance to rethink how they grow and move, and directs them towards more sustainable solutions for the future.
We help clients navigate all the complexities of CEQA and SB 743, leaning on our deep understanding of the relationship between technical decisions and the litigation risk associated with technical adequacy under CEQA and SB 743.




Supporting Sustainable Transportation Planning
One example of our work is VMT+, a first-of-its-kind visualizer developed with 2019 StreetLight data. VMT+ equips planners with detailed insights into VMT at the state, regional, and local levels, helping communities better understand VMT generation rates.

Public Agencies
We’re partnered with hundreds of public agencies to help navigate SB 743 implementation and complete impact studies.
Jurisdictions across California
Whether urban, suburban, or rural, implementing SB 743 works best when it reflects the local community.
