Comprehensive Transportation Projects

2050 Regional Transportation Plan

After two years of careful work and extensive public input, the SANDAG Board of Directors on Friday, October 28, 2011, adopted the 2050 Regional Transportation Plan (RTP) and Sustainable Communities Strategy (SCS), a balanced vision for the evolution of the region’s transportation system over the next 40 years. (View Board Agenda)

Many of the capital projects outlined in the RTP are now in development. For more information on these projects, visit and

As part of the action taken to approve the 2050 RTP and its SCS, Directors also approved:

• Evaluating alternative land use scenarios as part of the Regional Comprehensive Plan (RCP) update to attempt to address the so-called “backsliding” of greenhouse gas levels between years 2035-2050.
• Developing an early action program for projects included in the Regional Bicycle Plan.
• Planning for the broader Active Transportation program, including Safe Routes to School and Safe Routes to Transit, within the next two years.
• Implementing an action to develop a regional transit-oriented development policy in the 2050 RTP Sustainable Communities Strategy to promote and incentivize sustainable development.
• Continuing to make enhancements to the travel demand models; the activity-based models currently under development will be “open source” and available for the next RTP update.
• Developing a regional complete streets policy within the next two years.

A progress report on the work undertaken on these six commitments as of April 2016, has been prepared.

The 2050 RTP lays out a plan for investing an estimated $214 billion in local, state, and federal transportation funds expected to come into the region over the next 40 years. The largest proportion of the funds will go toward transit, which will receive 36 percent of the funds in the first 10 years, with 34 percent going to highway improvements (largely for the addition of high occupancy vehicle lanes to existing freeway corridors), and 21 percent to local roads and streets. The percentage dedicated to transit will grow each decade, up to 44 percent from 2021 to 2030, 47 percent in the third decade, and 57 percent in the last decade of the plan.

Along with the 2050 RTP, the Board adopted the Sustainable Communities Strategy (SCS). The SCS details how the region will reduce greenhouse gas emissions to state-mandated levels over time. The inclusion of the SCS is required by Senate Bill 375, and the San Diego region is the first in California to produce a regional transportation plan with an SCS.

The Board also adopted the Environmental Impact Report for the 2050 RTP and SCS. And the Board adopted the final Regional Housing Needs Assessment Plan.

About 4,000 public comments from nearly 1,500 individuals and organizations were received on the Draft RTP and its SCS. View the matrix of RTP/SCS comments and responses. SANDAG received 22 letters of comment on the Draft 2050 RTP/SCS EIR. EIR comments and responses are included in Appendix G of the EIR.

More than 200 community members turned out at the October 28 Board of Directors meeting to weigh in on the landmark 40-year plan. Many attendees provided public comment in advance of the final vote.

Appendix G (Public Comments and Responses)

The 2050 Regional Transportation Plan maps out a system designed to maximize transit enhancements, integrate biking and walking elements, and promote programs to reduce demand and increase efficiency. The RTP includes a Sustainable Communities Strategy that integrates how we use land, develop housing, and plan transportation. The SCS also addresses how the transportation system is developed in such a way that the region reduces per-capita greenhouse gas emissions to state-mandated levels. In June, SANDAG held public workshops and public hearings to provide the opportunity for public comment on the Draft 2050 RTP, SCS, AQCD, Environmental Impact Report, and Regional Housing Needs Assessment.

The 2050 RTP and its SCS were developed following more than two years of planning, technical development, outreach, and public input. A comprehensive Public Involvement Plan guided these outreach efforts.
