Achieving the state’s VMT reduction goals relies on the consistency of action at local levels. To ensure a successful and equitable outcome for local VMT-reducing policy implementation, such as SB 743, jurisdictions need resources and motivations to overcome obstacles that might hinder the process. They also must consider equity throughout the process and not just as the outcome. This three-chapter dissertation will study (1) the reasons behind the decisions of local jurisdictions, including cities and counties, about VMT reduction levels in their environmental reviews and (2) how local planners view equity in the process of implementing VMT-reducing strategies in the CEQA process. Additionally, the researchers will look at the land use projects that went through the VMT mitigation process to (3) show the impact of VMT mitigations on the future of the urban form. The researchers will have three data collection methods, including survey, interview, and case study. Three studies of the dissertation will include the following: 1. A model of driving factors for California substate jurisdictions to adopt progressive environmental policies: the researchers will survey planners from all jurisdictions in California to answer the research questions of this chapter. 2. An analysis of how planners perceive equity and efficiency in environmental planning, which will include interviews with planners and decision-makers to understand how they consider equity through the environmental policy design and implementation process. 3. A case study of land use projects before and after recent changes in the CEQA process and the development streamlining impact of SB 743.
