TIP Modification Process

The TIP and STIP are living documents that are subject to updates through a TIP Modification process.  There are four types of TIP modifications:

  1. TIP Amendment Type A – Adding or cancelling a project that significantly affects roadway capacity.
  2. TIP Amendment Type B – Adding or cancelling a federally funded, or regionally significant project (below Type A), major change in project scope or fiscal constraint.
  3. TIP Adjustment – Change to funding that the Policy Committee has discretion in programming, below full amendment level.
  4. Administrative Modification – Minor actions that are not described above, approved at staff level.

Refer to the TIP Amendment Matrix (PDF) for a more detailed description of the types of TIP modifications and a tool to help determine the appropriate modification level.
