A transit funding referendum for Los Angeles County passed in 1980 providing for a one-half cent sales tax for transit related projects. One quarter (25%) of the funds generated, (referred to as Local Return Funds) are earmarked for transit projects. Thirty five percent (35%) of the balance of the funds is allocated to rail projects. The remaining forty percent (40%) is discretionary between bus and rail, although currently it is all allocated to bus operating costs.
