Countywide Transportation Plan and Action Plans

Planning for Tomorrow's Transportation

The Contra Costa Transportation Authority (CCTA) is updating the Countywide Transportation Plan (CTP), including the identification of future transportation system improvements through multimodal planning, program, and project-related investments in Contra Costa County through 2050.

CCTA is conducting a Summer Outreach Event Series designed to gather input from members of the public to help understand unique perspectives, ideas, and needs related to transportation to inform the CTP update. The series features an array of engaging community events in every city/town throughout the County to ensure a comprehensive and inclusive outreach effort that engages as many residents and visitors as possible.

Countywide Transportation Plan (CTP)

The CTP provides overall direction for achieving a balanced and functional transportation system in Contra Costa County and coordinating land use decisions with transportation needs. It outlines the countywide vision for the future and provides goals, measurable objectives for performance monitoring, strategies, projects, and actions to achieve that vision.

To review the adopted 2017 CTP, visit the 2017 CTP page.

The CTP update will identify new and emerging issues, ideas, and technologies affecting multimodal transportation in Contra Costa. Community input will inform development of the CTP Update in addition to engagement of key stakeholders, advocacy groups, community-based organizations (CBOs), and non-governmental organizations (NGOs). CCTA anticipates publishing the Draft CTP in late 2024 and taking the Final CTP to the Authority Board for adoption in Spring 2025. An Environmental Impact Report (EIR) will be prepared concurrently with the CTP update for compliance with the California Environmental Quality Act (CEQA).

In early 2023, CCTA facilitated the completion of the five subregional Action Plans (see map below), which will be integrated into the CTP update. The Action Plans are intended to reduce the impact of new development on the county transportation system in compliance with the Measure J Growth Management Program (GMP), which requires local cities/towns and the County to participate in a cooperative land use and transportation planning process.

Measure J History

In 1988, Contra Costa County voters approved Measure C, a one-half percent sales tax that generated $1 billion in funding over 20 years. Measure C also included the Growth Management Program (GMP) that encouraged local jurisdictions to participate in a cooperative, multi-jurisdictional planning process, and, among other things, establish flexible traffic service standards for Regional Routes to reflect the varying urban, suburban, and rural settings in the county. In 2004, Measure J was passed by the voters of Contra Costa, extending the sales tax program and the GMP for another 25 years. CCTA, created to manage this program, allocates 18 percent of the sales tax revenue it receives to local jurisdictions that comply with Measure C and J requirements.  To receive these funds, each Contra Costa jurisdiction must, among other requirements, participate in an ongoing cooperative, multi-jurisdictional planning process. As a part of this process, Action Plans are developed and updated with input from local jurisdictions. The current process marks the fourth major update of the Action Plans.
