A TIP revision is a change that is made between full updates of the TIP.  The TIP is regularly revised to update project information, as well as to add or delete projects.  There are two types of TIP revisions – Amendments and Administrative Modifications.

Amendments

A TIP revision is a change that is made between full updates of the TIP.  The TIP is regularly revised to update project information, as well as to add or delete projects.  There are two types of TIP revisions – Amendments and Administrative Modifications. 

An amendment involves a major change to a project in the TIP.  An amendment to the TIP requires an opportunity for review and comment by the public and is approved by the HRTPO Board.  A TIP request that involves any of the following items must be processed as an amendment: 

  • Addition/deletion of a project.
  • Addition/deletion of a project phase.
  • Major change in design concept, scope, or termini.
  • Major change in project phase initiation date (6 to 12 month delay).
  • Ungrouping of a TIP project to add back into the TIP as an individual project
  • Major change in project cost as determined by the Sliding Scales below:

Administrative Modifications

An Administrative Modification (Ad-Mod) involves a minor change to the TIP.  Administrative Modifications will be included as attachments to a standing HRTPO Board agenda note each month to inform Board members of the status of locality/agency TIP projects.  The following are examples of items that may be processed as Administrative Modifications: 

  • Minor changes in project/phase costs (see Sliding Scales on previous page).
  • Adding/transferring/swapping/deleting allocations to a project, including CMAQ and RSTP funds
  • Adding/removing obligations.
  • Splitting or combining individually listed projects with no major change in scope/termini
  • Minor project schedule changes.  Ad-mods with subsequent schedule project delays will be reviewed on a case-by-case basis.
  • Project name/description change with no major change in scope.
  • Minor changes to funding sources of previously included projects, including a change in the source of funds (e.g: change from non-Federal to Federal, change in type of Federal funds, or change in type of non-Federal funds).
