Countywide Transportation Plan

The Countywide Transportation Plan (the Plan) 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. CCTA is currently updating the CTP Plan to best reflect our current transportation needs and priorities. 

Update Process and Timeline

The Plan will help identify how and where transportation investments in Contra Costa County should be prioritized. Community feedback will inform development of the Plan Update in addition to input from key stakeholders, advocacy groups, community-based organizations (CBOs), and non-governmental organizations (NGOs). CCTA anticipates publishing the Draft CTP in early 2026 and taking the Final Plan to the Authority Board for adoption in mid-2026. An Environmental Impact Report (EIR) will be prepared concurrently with the update for compliance with the California Environmental Quality Act (CEQA).

Phase 1 Engagement: What We Heard 

 CCTA kicked off engagement for the Plan in late 2024 with an online survey, a series of pop-up events, and stakeholder meetings. We heard strong support for the four guiding principles for the Plan: (1) Safe Travel, (2) Growing Sustainably, (3) Livable and Connected Neighborhoods, and (4) Access for All.  

Community members expressed interest in improving transit options and opportunities for using autonomous vehicles. People also shared the importance of making driving across the county safer and easier.  

This input helped to shape the proposed Transformative Visions that we are currently gathering feedback on in the online open house and survey.

County Subregion Action Plans

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.
