2018 Regional Transportation Improvement Program

View the Final 2018 Regional Transportation Improvement Program

SANDAG, as the Metropolitan Planning Organization and the Regional Transportation Planning Agency, is required by state and federal laws to develop and adopt a Regional Transportation Improvement Program (RTIP).

The RTIP is a multi-billion dollar, multi-year program of proposed projects for major transportation projects in the San Diego Region. Transportation projects funded with federal, state and TransNet, the San Diego transportation sales tax program managed by SANDAG, must be included in an approved RTIP. The programming of locally funded projects also may be programmed at the discretion of the agency.

The RTIP covers five fiscal years and incrementally implements San Diego Forward: The Regional Plan, the long-range transportation plan for the San Diego region. The current Regional Plan was approved by the SANDAG Board of Directors at its meeting on October 9, 2015. 

At its meeting on September 28, 2018, the SANDAG Board of Directors adopted the final 2018 RTIP.  SANDAG anticipates a federal approval date in December 2018.

Group Project Listing

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).' Once grouped, the MPO is required to maintain, outside of the RTIP a detail list of the projects contained in each group.

Federal Air Quality Conformity Requirements

Federal regulations require SANDAG to conduct an air quality conformity analysis of all regionally significant projects that increase the transportation system capacity. All regionally significant capacity increasing transportation projects regardless of funding sources must be included in the RTIP.

Additional information on conformity can be found on the Conformity Working Group web page.

Congestion Management Process

All local agency Single Occupant Vehicle (SOV) capacity increasing projects seeking federal funds are required to perform a multimodal alternative and non-SOV analysis prior to submitting the projects for inclusion in the RTIP. Agencies are required to submit the analysis as part of the project submittal either as an upload in ProjectTrak.

Additional information regarding this process can be found in Appendix U.7 of the Regional Plan or on the Congestion Management Process web page.
