Automobile delay (as measured solely by roadway capacity or traffic congestion) cannot constitute a significant environmental impact, even for projects that were approved before the new CEQA guidelines on transportation impacts were certified in December 2018. Citizens for Positive Growth & Preservation v. City of Sacramento, 2019 WL 6888482.
The case involved a challenge to the City of Sacramento’s 2035 General Plan, which it adopted in March 2015. The plaintiff alleged that the city violated CEQA and the Planning and Zoning Law.
CEQA: Transportation Impacts
Analyzing Transportation Impacts Under CEQA. Public Resources Code section 21099 (commonly known as SB 743) directed the Office of Planning and Research to develop guidelines for assessing transportation impacts based on vehicle miles traveled (VMT). SB 743 provides that upon certification of implementing guidelines by the Natural Resources Agency, “automobile delay, as described solely by level of service [LOS] or similar measures of vehicular capacity or traffic congestion shall not be considered a significant impact on the environment . . . except in locations specifically identified in the guidelines, if any.”
Section 15064.3 of the CEQA Guidelines, adopted in 2018 to implement SB 743, provides that, except for roadway capacity projects, “a project’s effect on automobile delay shall not constitute a significant environmental impact.” Further, the SB 743 guidelines specify that generally, VMT is “the most appropriate measure of transportation impacts.” The guidelines apply prospectively, and apply statewide beginning July 1, 2020, unless an agency elects to be governed by them sooner. (For a detailed analysis, see our report on the SB 743 Guidelines.)
