This Vision will be a fundamental part of the forthcoming San Diego Forward: The 2021 Regional Plan, which will provide a blueprint for increased mobility in the San Diego region through 2050. By mid-century, our region is projected to be home to 3.75 million people, and the health of our regional economy, our state mandated goals for reducing greenhouse gases and protecting the environment, and maintaining and improving the overall quality of life for
