Next 10 Delivery Plan

Keeping the Promise

The OCTA Board approved the OC Go Next 10 Delivery Plan (Next 10 Plan) on November 14, 2016. This comprehensive and balanced plan was developed to ensure that the promises made in the OC Go Investment Plan (OC Go Plan) can continue to be delivered in concert with changes in economic conditions and revenue projections. While the Next 10 Plan sets a course for accelerated delivery through 2026, it also ensures that the entire 30 year OC Go Plan of projects and program commitments can be delivered through 2041.

On November 11, 2019, the OCTA Board approved the 2019 Next 10 Plan. The 2019 OC Go sales tax forecast increased by $300 million (through 2041) to $13.4 billion.

On October 26, 2020, the 2020 OC Go sales tax forecast of $11.6 billion was presented to the Board, which reflects a $1.8 billion decrease (through 2041) due to the economic impacts of the coronavirus (COVID-19) pandemic. Staff is reviewing the cash flow assumptions and incorporating updated project cost and schedules for the 2020 Next 10 Plan update. The updated 2020 Next 10 Plan is anticipated to be presented to the Board in early 2021.

OC Go Timeline

Since the approval of OC Go, the OCTA Board has continued to advance implementation of OC Go 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 slower growth in sales tax revenue projections.
