SB743 Regional Guidelines and Toolkit

In 2013, Senate Bill 743 was signed into law, changing the California Environmental Quality Act (CEQA) project review process from using the level of service grade system to vehicle miles traveled (VMT) as the primary transportation impact metric. This shifted the project-level evaluation and impact assessment system from an average level of traffic to the amount of miles traveled by all vehicles to better track vehicle use and vehicle emissions.  

MCAG is preparing an SB 743 Implementation Plan to prepare regional guidelines and a toolkit for the seven jurisdictions: City of Atwater, City of Dos Palos, City of Gustine, City of Livingston, City of Los Banos, City of Merced, and the County of Merced. This plan will include identifying and establishing project screening criteria, methodologies for estimating project specific VMT, regional and local thresholds, and VMT mitigation strategies.
