Highways and polluting facilities, such as refineries, rail yards, and factories, are often located in close proximity to low-income communities and communities of color in LA County. These communities face elevated health risks from pollutant exposure and have historically been overburdened and under-resourced. The Antelope Valley and other rural communities face ongoing challenges because of illegal dumping, which can degrade natural landscapes, pose risks to water quality and public health, and strain local infrastructure. OurCounty establishes a framework for long-term policies to better protect these communities from pollution and reduce health inequities, with near- and medium-term actions that support these goals.
