Reducing environmental and health disparities and improving the health of Washington state residents in large port districts.

HB 1948 requires Washington state port districts managing major airport operations (defined as those with significant capital projects over $8 million) to create environmental justice plans by 2026. These plans must include community engagement strategies, measurable goals to reduce health disparities, and methods to involve overburdened communities in decision-making. For major projects, ports must obtain University of Washington assessments of environmental impacts on vulnerable populations and publicly share mitigation plans. The law mandates accessible community input through language support, childcare, and outreach to ensure equitable participation. It applies specifically to ports with airport-related activities under RCW 53.54.010.
