This legislation, known as the MORE DOT Grants Act, seeks to enhance the ability of specific rural areas to secure federal transportation funding. It targets "High-Density Public Land Counties," defined as those with populations under 100,000 where over 50 percent of land is federally owned or managed, along with local and Tribal governments within these counties. The bill applies to a wide range of existing Department of Transportation (DOT) discretionary grant programs, including those for infrastructure, rural surface transportation, and public transit. A core provision of the bill is the 50 percent reduction in local matching fund requirements for eligible High-Density Public Land Counties and their local or Tribal governments. Additionally, the Secretary of Transportation is directed to provide additional technical assistance upon request, both before and during the annual application period for qualifying grant programs. This support is intended to help these communities navigate the often-complex federal grant application process more effectively. The bill also establishes application priorities, giving preference to eligible entities that have not received support under a specific qualifying grant program during the preceding 10 years. Furthermore, the Secretary is mandated to give special consideration to applications from these counties and local governments for any rural set-aside funds designated by Congress. Tribal governments within these counties may also receive special consideration for such set-asides. Finally, the legislation authorizes the Secretary to provide other support and offer flexibility regarding certain application requirements or barriers. This includes addressing scoring criteria that disadvantage small communities, requirements for partnerships that may not be feasible locally, financial requirements unrelated to an applicant's overall financial health, and overly complicated application processes. These measures aim to remove systemic obstacles and ensure more equitable access to federal transportation funding for these specific rural and Tribal communities.
