Health Impact Assessments (HIAs) are powerful tools for making informed decisions that improve public health through community design that can positively affect health equity. While Environmental Impact Statements have become standard procedure for making sound development decisions and protect environmental interests, HIAs are still underutilized in project selection and development. Effective use of HIAs highlights how specific developments affect health in certain populations, helping to address health inequities by prioritizing key transportation and infrastructure projects in low-income and disinvested communities. CMAP and partners should develop materials and trainings for local governments looking to conduct HIAs that use health equity concepts and goals in the planning and development processes of major transportation and infrastructure projects.
