SB 743 Compliance / Vehicle Miles Traveled (VMT)

We cherish our history yet continue to look forward. LLG’s work continues to evolve in partnership with public agencies, communities and private sector clients by providing Senate Bill (SB) 743/VMT assessments that include context-sensitive, data-rich, holistic solutions to mobility.

In September 2013, Senate Bill (SB) 743 was adopted and changes the way transportation impacts are assessed under the California Environmental Quality Act (CEQA). The guidelines shift from Auto Delay/Level of Service (LOS) to Vehicle Miles Traveled (VMT) as the most appropriate metric to measure of transportation impacts. The State of California Governor’s Office of Planning and Research (OPR) has released draft CEQA Guidelines and Technical Advisory which can be accessed below.

Technical Advisory On Evaluating Transportation Impacts In CEQA

Partnering with SANDAG, LLG is an industry leader in determining VMT and has co-authored a white paper detailing the methodology to calculate VMT using the SANDAG regional travel demand model. LLG/SANDAG received the Most Educated About GIS award for the development of the VMT Analysis Methodology presented at the ESRI International GIS Conference. Since the publishing of the white paper, LLG continues to immerse itself into alternative measures of effectiveness for traffic analyses. LLG extrapolates various types of data from the SANDAG regional model, GPS data analytics, CENSUS records, and other sources for use in environmental assessments. LLG also takes an active role with presentations and/or participation in working groups related to SB 743/VMT for professional societies such as ITE, AEP, and APWA.
