Surface Transportation Block Grant (STBG) & Congestion Mitigation and Air Quality Improvement Programs (CMAQ)
The Surface Transportation Block Grant (STBG) program provides federal transportation funding for projects that preserve and improve the conditions and performance of highways, bridges, and public roads; pedestrian and bicycle infrastructure; and transit capital projects.
The Congestion Mitigation and Air Quality (CMAQ) Improvement Program provides federal transportation funding for projects and programs that reduce traffic and improve air quality for areas that do not meet the National Ambient Air Quality Standards for ozone, carbon monoxide or particulate matter (nonattainment areas) and for former nonattainment areas that are now in compliance (maintenance areas).
In alignment with its role shepherding implementation of the Connect SoCal 2024 Regional Transportation Plan/Sustainable Communities Strategy, SCAG is responsible for the project selection process for STBG and CMAQ funds in the region. The SCAG STBG/CMAQ Program Guidelines outline the process and procedures for the calls for project nominations and project selection.
Eligible applicants for SCAG-administered STBG/CMAQ calls for project nominations include SCAG cities, counties, transit agencies, federally recognized Tribal governments, and county transportation commissions.

Frequently Asked Questions
- Is this a one-time funding opportunity? When will the next call for projects be?
Though SCAG does not currently have estimates for subsequent federal fiscal year apportionments, SCAG expects to administer similar size calls for projects every odd year. The current federal surface transportation authorization, the Infrastructure Investment and Jobs Act (IIJA), is set to expire in September 2026. After the expiration of the IIJA, future years of funding will be subject to federal surface transportation reauthorization, continuation, or other congressional action.
- My project received a funding award. What i’s the next step?
Project sponsors should work directly with their county transportation commission staff to program these awarded STBG/CMAQ funds into the FTIP. Upon FTIP approval, the project sponsor can begin the obligation process with Caltrans Local Assistance respective District staff. More information regarding the obligation process and federal funding requirements is outlined in Caltrans’ Local Assistance Procedures Manual.
- My project is on the contingency list. What is the next step?
Projects on the contingency list will be awarded funding as it becomes available. All aAvailable funding will be prioritized for partially awarded projects and projects on the contingency list with a “Highly Recommended ranking.” SCAG and the county transportation commissions will reach out to the project sponsors if a funding opportunity becomes available.
- My project is on the not recommended list. What is’s the next step?
Projects on the not recommended list may resubmit their application in the upcoming call cycle to be considered for funding awards. The next call for project nominations is anticipated to take place in calendar year 2027.
- Will awarded projects receive an memorandum of understanding (MOU) or grant agreement from SCAG?
No, SCAG will not be engaging in MOU or grant agreements for STBG/CMAQ funds. Project sponsors will establish program supplement agreements as applicable for STBG/CMAQ funds directly through Caltrans Local Assistance.
- What if my awarded project has changes to the schedule, cost, or scope?
Procedures regarding post-award changes to project schedule, cost, and scope will be outlined in the SCAG Programming Procedures for FHWA-Administered Funding. These procedures are anticipated to be presented to the Regional Council for approval in February 2026.
- What are the obligation deadlines for the awarded CMAQ/STBG funds?
Obligation deadlines will be set on an annual basis. In general, STBG/CMAQ projects awarded through the 2023-2026 call cycle have no later than Sept. 30, 2028, to obligate their funds. STBG/CMAQ projects awarded through the FFY 2026-27 and FFY 2027-28 cycle have no later than Sept. 30, 2030, to obligate their funds.
2023-2026 Award Recipients
On June 6, 2024, the SCAG Regional Council approved 2023-2026 STBG/CMAQ funding recommendations for $186.9 million across 33 projects within the SCAG region. Projects approved by SCAG for STBG/CMAQ funding must be programmed in the Federal Transportation Improvement Program.
