This summary provides Tribal decisionmakers and planners with a brief summary of the process for developing a Tribal Transportation Improvement Program (TTIP). It is based on the module Developing a Tribal Transportation Improvement Program, which is one of eight modules in the series Transportation Decisionmaking Information Tools for Tribal Governments written by the FHWA Office of Planning to educate Tribal planners and decisionmakers about the Tribal transportation planning process, and to provide them with program information.
The TTIP is a prioritized list of transportation projects that the Tribe expects to undertake over the next three to five years based on the funding that it expects will be available during that time. This is different from the Tribal Priority List, which contains all transportation projects the Tribe would like to complete if money were not a limiting factor.
Projects included in the TTIP reflect the Tribe's transportation vision, goals, and needs presented in the Tribal Long-Range Transportation Plan (LRTP)-a more general planning document that considers the Tribe's needs and trends in transportation and related topics over the next 20 years.
There are four steps in developing the TTIP. They include the following:
Involving stakeholders-people and groups with an interest in Tribal transportation issues-is key to identifying and understanding the needs and priorities of the community. Stakeholders include Tribe members, government agencies, transit providers, human service agencies, local businesses, and others. At a minimum, Federal regulations require that the Tribe or Bureau of Indian Affairs (BIA) office publicize a draft TTIP and provide an opportunity for stakeholders to review and submit comments. Tribes often conduct public meetings for this requirement.
With the prioritized transportation needs identified in the LRTP, the Tribe must choose projects for the TTIP that will best meet and serve those needs. Project identification and selection requires the Tribe to define the purpose and need of each potential project. It might also do preliminary assessments of candidate projects to understand a project's pros and cons. This assessment might include, for example, a rough estimate of project costs or a broad understanding of how the project might affect the human and natural environment. After this preliminary assessment, the Tribe can choose from this list of potential transportation projects based on how they meet the needs of the Tribe and its stakeholders considering the cost and other possible benefits and impacts of each project.
The BIA, FHWA, and the Federal Transit Administration (FTA) each have programs that fund transportation projects on Tribal lands. State and local governments might also have money available. Tribal planners and decisionmakers can consult with BIA, FHWA, and other government agencies to help determine what total funding is available, how funds might be secured for the TTIP projects and the requirements associated with each funding source.
After identifying specific projects to include in the TTIP, the Tribe should develop individual project cost estimates. They can generate the cost estimates in-house by using guidelines developed by FHWA or BIA. Alternatively, a transportation consultant can be hired for this task. Estimates should include the costs to design, construct, and maintain the transportation facility.
If a Tribe develops a TTIP, Federal law requires that it be incorporated into the Indian Reservation Roads Transportation Improvement Program (IRRTIP) developed by the BIA region and incorporated into the Statewide Transportation Improvement Program (STIP) developed by the state government. Tribal projects may also be included in transportation improvement programs developed by nearby metropolitan planning organizations. The following table shows the government agencies that must or can include TTIP projects in their own transportation improvement programs.
|Government Agency||Transportation Improvement Program||Jurisdiction||Legally Required Relationship between Transportation Improvement Programs|
|Bureau of Indian Affairs (BIA)||Indian Reservation Roads Transportation Improvement Program (IRRTIP)||BIA region||Must contain projects from TTIP|
|Metropolitan Planning Organization||Transportation Improvement Program (TIP)||Designated metropolitan planning area||
|State Department of Transportation||State Transportation Improvement Program (STIP)||Statewide||Must contain all projects from IRRTIP|
Staff from the BIA, FHWA Federal Lands Highway, and FHWA Federal-Aid Division Offices can provide additional information to Tribes interested in learning more about developing a TTIP.
