Like many regions in California, SANDAG is increasingly dependent on local “self-help” taxes to fund major transportation investments. The need for self-help measures throughout the state has grown as federal and state funding sources have been stagnant and in some cases intermittent. Despite this, both federal and state funding is significant and provides considerable flexibility that SANDAG can use to meet critical transportation goals for the region. This is not an exhaustive list of all the funding sources available but a review of those that figure most prominently in this discussion.
