Past Regional Plans
2021 Regional Plan
Project Overview
In December 2021, the Board of Directors adopted the 2021 Regional Plan and certified its accompanying Environmental Impact Report (EIR). Due to significant community advocacy, SANDAG developed an amended plan to remove a regional road user charge as one of the possible future funding sources for the transportation network. In fall 2023, the Board adopted the final Amended 2021 Regional Plan and certified the Supplemental Environmental Impact Report (SEIR).
This plan was the result of years of planning, data analysis, and community engagement to reimagine the San Diego region with a transformative transportation system, a sustainable pattern of growth and development, and innovative demand and management strategies. The amended plan and SEIR provided information to decision makers, members of the public, and public agencies.
The plan complies with state and federal mandates, including Senate Bill 375 (Steinberg, 2008), that mandates a Sustainable Communities Strategy that achieves greenhouse gas emission reduction targets set by the California Air Resources Board (CARB). It also complies with federal civil rights requirements (Title VI), air quality conformity, and a public participation process.

EIR Documents
As required by the California Environmental Quality Act (CEQA), the EIR analyzed the environmental impacts of the 2021 Regional Plan on resources like air quality, water, land use, biological resources, greenhouse gas emissions, and more. It also analyzed cumulative impacts, identified environmental mitigation measures, and examined the environmental impacts of not implementing the 2021 Regional Plan (No Project Alternative).

2015 Regional Plan
Project Overview
The 2015 Regional Plan prioritizes 35 years of regional transportation projects to create a framework for much of the region’s transportation infrastructure. It serves as a blueprint for how SANDAG invests in transportation infrastructure that will provide more choices, strengthen the economy, promote a healthy environment, and support thriving communities.
The 2015 Regional Plan was published under the title, San Diego Forward: The Regional Plan.
