Comprehensive Transportation Projects

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 will be asked to adopt the final 2018 RTIP.  SANDAG anticipates a federal approval date in December 2018.

2018 RTIP Update Schedule

SANDAG is in the process of developing the 2018 RTIP.  A memo detailing the process, requirements, and schedule was emailed out on January 16, 2018, and is also below under the Downloads section.  All regionally significant and/or capacity increasing (CI) transportation projects are required to be included in the RTIP and incorporated into the air quality quantitative emissions analysis.  In addition, all projects included in the 2018 RTIP must be consistent with San Diego Forward: The Regional Plan. Below lists some significant milestones for the 2018 RTIP Update process.

March 16, 2018 – All projects are due in ProjectTrak 

June 29, 2018 – All resolutions must be uploaded in ProjectTrak

July 27, 2018 – SANDAG Board is scheduled to release the draft 2018 RTIP for public comment

September 7, 2018 – SANDAG Transportation Committee is scheduled to hold a public hearing for the 2018 RTIP

September 28, 2018 – SANDAG Board is scheduled to adopt the final 2018 RTIP

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 or in a CD format.

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