2025 Regional Plan

Final Regional Plan Adopted: On Friday, December 12, the SANDAG Board of Directors adopted the 2025 Regional Plan and certified its accompanying Environmental Impact Report. Final documents are available below.

The goal of the 2025 Regional Plan is to make transportation more convenient, equitable, healthy, and safe for everyone in the San Diego region. It includes short- and long-term plans for improving our transportation system.

The plan creates a transportation network that is accessible and interconnected with improvements to existing projects and other new projects that are supported by programs, policies, and implementation actions, as well as a financial plan.

Our mandates include requirements related to GHG emissions, Title VI, accessibility, and public participation. The plan also addresses infrastructure, land use, housing, and environmental needs of the region. As required by the California Environmental Quality Act (CEQA), SANDAG also prepared an environmental impact report (EIR) for the 2025 Regional Plan.

How You Helped Build This Update

The 2025 Regional Plan is built on significant input from our region’s communities. The Board and Policy Advisory Committees (PACs), working groups, partner agencies, and community members in all six subregions provided input through interactive workshops. We listened to and considered comments from our online interactive map tool and pop-up feedback collection events hosted by community-based organizations. Thank you for being a vital part of the process.

The Draft 2025 Regional Plan was released on May 23, 2025 for a 56-day public review period which concluded on July 18, 2025. A public hearing on the plan was held at the Transportation Committee meeting on July 18, 2025. Every comment received during the public review period was carefully reviewed, considered, and addressed. All comments received during the public comment period, as well as grouped responses to public comments, are included in Appendix J Attachment J6. Appendix J also includes detailed documentation of all outreach events leading up to the release of the 2025 Regional Plan.
