  • Measure M

    Measure M, Orange County’s half-cent transportation sales tax, continues to make a significant difference in the lives of residents who benefit every day from improvements on freeways, streets and roads, and the transit system.
  • Measure M Amendment to Reallocate Transit Funds Approved

    Following a public hearing during the December 14th board meeting, the OCTA Board of Directors approved an amendment to Measure M, Orange County’s half-cent sales tax for transportation improvements. The amendment will take effect on January 28, 2016, closing out Project T (gateways to high speed rail) and reallocating the balance to Project U to cover a shortfall in the Senior and Disabled Fare Stabilization Program and Project R, which funds the ongoing operation of Metrolink service in Orange County.

    Project T has a capital investment emphasis, Project U has an operational emphasis, and Project R has a mix of capital and operations. While the amendment adjusts the relative amount of expenditures among three transit programs, it does so in the spirit of fulfilling the voter commitment by addressing the needs of two programs using cost savings from a completed program.

    The amendment was proposed following the recently completed Ten-Year Comprehensive Program Review (2006-2016) of the Measure M Investment Plan that evaluated the performance of the overall program and provided recommendations to improve performance (report summary).

  • About Measure M

    Voters first approved Measure M in 1990 for a 20-year period. Their trust was rewarded by more than $4 billion in transportation improvements, including adding 192 freeway lane miles, improving 170 intersections and 38 freeway interchanges, and implementing Metrolink service in Orange County. After experiencing 20 years of success and progress, voters renewed the sales tax for transportation improvements in 2006 for another 30 years.
