A project's "Need" is an identified transportation deficiency or problem, and its "Purpose" is the set of objectives that will be met to address the transportation deficiency. A reasonable solution or range of solutions is developed and evaluated based on these objectives.
A clear, concise, well justified Purpose and Need statement is the foundation of every transportation project. It is critical for identifying a reasonable range of project alternatives; it expedites project delivery; and it leads to a more precisely defined project scope, schedule, and cost. Just as importantly, it explains to the public, stakeholders, and decision makers that the expenditure of funds is necessary and worthwhile, and that the project‘s priority relative to other transportation projects is warranted. It ensures that the right project is built.
A quality Purpose and Need statement also meets the requirements of federal and state regulations: an Environmental Impact Statement shall "briefly specify the underlying purpose and need to which the agency is responding in proposing the alternatives including the proposed action" (40 CFR §1502.13); an Environmental Impact Report shall "contain a statement of objectives sought by the proposed project" and it "should include the underlying purpose of the project" [14 CCR §151.24(b)].
A project's basic purpose and need must be founded in a transportation planning document and will remain consistent throughout project development. As supporting data and input are assembled during the project approval process, these can be used to refine the solutions being considered, thereby permitting a more focused analysis of those solutions that truly address the problem to be solved. All subsequent project activities must reflect this final project purpose and need. Key factors in the successful development and refinement of a sound Purpose and Need statement include broad participation from functional units and stakeholders. It is also crucial that project data are transmitted and retained for each phase of the project development process.
