Draft 2023 TIP Grouped Listings

Federal regulations allow MPOs to group or combine projects that are not considered to be of appropriate scale for individual listing. Such projects may be grouped by function, work type or geographical area and must be consistent with the exempt project classification contained in EPA's "Transportation Conformity Regulations (40 CFR part 93)." Such grouped projects are often referred to as "Lump Sum Projects Listings." Once grouped, the MPO is required to maintain a detailed list of the projects contained in each group outside of the TIP.
