At the center of demands for cleaner air, water, and soil in communities disproportionately impacted by environmental hazards, are often cities and counties. Local jurisdictions are uniquely positioned to shape policies and engage with residents in processes that can transform land-use patterns that have negatively impacted low-income, people of color communities. This study assesses the approaches to environmental justice (EJ) that California local jurisdictions with high levels of cumulative environmental health impact are developing in their general plans, under Senate Bill 1000. Results indicate positive outcomes such as the establishment of EJ advisory committees. However, findings also underscore challenges such as a lack of political support from elected officials and minimal resources to implement measures. We find that most general plans include EJ considerations, however, there are concerns regarding how their implementation will unfold. We provide practice-based recommendations to assist planners across the nation working to develop effective EJ considerations.
