TIP Amendment

The Transportation Improvement Program (TIP) is the mechanism by which federal, state and local funds are approved for all significant surface transportation projects and programs in the region. The FY 2020-2025 TIP comprises the first six years of the Regional Transportation Plan (RTP) for the Atlanta region. As the federally recognized Metropolitan Planning Organization (MPO) for a 20-county region, ARC is responsible for developing and amending/updating the TIP and RTP to meet federal planning requirements and address local needs.

Currently, staff are compiling changes to be considered for an amendment to the RTP and update to the TIP.

Purpose of Regional Transportation Plan Amendment 6 / Transportation Improvement Program Update

  1. Include the addition of new non-exempt TIP solicitation projects impacting air quality conformity
  2. Incorporate changes to project limits and financing from the Major Mobility Investment Program (MMIP)
  3. Extend the period of time covered by the TIP from FY 2020-2025 to FY 2023-2028
  4. Address project cost estimate and programmatic changes that are of a time sensitive nature or cannot be handled administratively.

All amendments require a conformity determination from the US DOT, in consultation with the US Environmental Protection Agency (EPA). This amendment is expected to receive an updated conformity determination by the US DOT and US EPA by January 2023. The most recent conformity determination was issued by US DOT and US EPA on June 14, 2022.
