Section 5: Planning and the Environment
Anchor: #i1008482Overview
Before projects are developed for construction, TxDOT districts, local governments, metropolitan planning organizations (MPOs), transit agencies, and others identify transportation needs through traffic and mobility studies. Projects are developed from identified needs. Planning covers short and long range requirements. As needs are further developed, projects emerge. This section covers the following aspects of planning and the environment:
- plan types
- how environmental considerations fit in.
Plans, Programs and Studies
A project might begin in a system-wide plan (such as a MPO long-range plan). The next step is to further develop Priority 2 [or long range planning status of TxDOT’s unified transportation program (UTP)]. Finally, a project moves to a “three-year plus one year letting” transportation improvement program (TIP) when actual project development is funded. Individual documents shown in the table are linked to additional explanation furnished in the Planning Manual.

How Environmental Considerations Fit In
A number of opportunities for consideration of environmental consequences occur in both the planning and the prog
