Governor Brown signed Senate Bill (SB) 743 in September 2013. It requires changes on how public agencies should evaluate the transportation impacts of projects under the California Environmental Quality Act (CEQA). In December 2018, the California Natural Resources Agency finalized updates to the CEQA Guidelines that incorporated the mandate from SB 743. The Guidelines identify Vehicle Miles Traveled (VMT) as the most appropriate metric to assess a project’s transportation impact, as opposed to using Level-of-Service (LOS). With SB 743, automobile delay no longer constitutes a significant environment effect under CEQA.
