There are a number of formula transit programs that can be used to invest in new transit capital and expansion as well as maintenance of existing systems.[7] It is important to note that in most cases federal rules prohibit the use of these funds to operate transit systems. This federal restriction represents a significant obstacle to the region’s ability to build and operate a robust, affordable, and efficient transit system. This limitation is one that SANDAG has committed to address through a future regional sales tax vote, often referred to as a “Quality of Life” measure.
