Measure M
Next 10 Delivery Plan
Keeping the Promise
The Measure M2 (M2) Next 10 Delivery Plan (Next 10 Plan) outlines OCTA’s priorities and funding commitments for delivering transportation improvements funded through the voter-approved M2 Transportation Investment Plan (Plan). The plan provides a forward-looking framework for advancing freeway, street, transit, and environmental projects while ensuring that all commitments of the M2 Program remain achievable through 2041.
The Next 10 Plan is regularly updated to reflect changes in economic conditions, sales tax revenue forecasts, external funding opportunities, and refined project schedules and costs. These updates help maintain a realistic delivery strategy while continuing to accelerate improvements that benefit Orange County residents, commuters, and businesses.
On October 26, 2026, the OCTA Board of Directors (Board) received the updated M2 sales tax revenue forecast of approximately $13.5 billion through 2041, representing a $300 million increase from the 2025 forecast. Sales tax collections for fiscal year (FY) 2025-26 totaled $447.0 million, a 3.5 percent increase from the prior year. While revenue forecasts fluctuate with economic conditions, ongoing reviews of project costs, schedules, and available external funding continue to demonstrate that the overall M2 program remains deliverable.
On November 9, 2026, the Board approved the 2026 Next 10 Plan that spans FY 2026-27 through FY 2035-36. The plan serves as a living document that is updated periodically to reflect evolving revenue projections, project readiness, and funding opportunities. Through this adaptive approach, OCTA continues to maintain fiscal responsibility while advancing transportation improvements that keep Orange County moving.
M2 Timeline
Since the approval of M2, the OCTA Board has continued to advance implementation of M2 through the adoption of a series of early delivery plans. These early delivery plans are designed to ensure the delivery of all projects and programs through 2041 as promised to the voters. These plans also bring transportation improvements earlier to residents and commuters of Orange County, and, as appropriate, address fluctuations in sales tax revenue projections.
