The Equitable Transit Oriented Development Support Act aims to enhance transportation finance infrastructure in the United States by supporting community development financial institutions (CDFIs) in funding transit-oriented development projects. The legislation focuses on improving access to public transportation and promoting community development in underserved areas, particularly benefiting low-income communities. Key provisions include the establishment of a CDFI Transit-Oriented Development (TOD) account, allowing CDFIs to receive loans for projects that improve public transit access.
