The Central County Community Connections Plan (or 4CP for short) will document community-identified projects and near-term priorities to address barriers and improve safety, connectivity, and climate resilience in communities adjacent to I-238 and I-580 between I-880 and Castro Valley BART.
The 4CP begins with a focused needs assessment to confirm community priorities before co-developing proposed improvements and workshopping project design concepts at several of the highest-need locations through extensive public engagement. The final 4CP will identify implementation pathways to deliver these community-prioritized projects in the near-term.
Given the timing of the 4CP, Alameda CTC will coordinate with and complement two Community-Based Transportation Plan (CBTP) planning grants Alameda CTC recently funded for the City of Hayward and the area surrounding the Bay Fair BART Station. The 4CP will also serve as a key opportunity to identify local transportation needs and strategies that may inform the 2026 Countywide Transportation Plan.
Plan Goals
The 4CP has five core goals that reflect community feedback from previous planning efforts and are aligned with current county, regional, and state transportation priorities:
- Prioritize safety
- Improve access and connectivity
- Support transit
- Strengthen climate resilience
- Facilitate community placemaking

The “study area” is defined by a half-mile buffer on either side of the I-238 and I-580 freeway right-of-way between I-880 and Castro Valley BART.
Timeline
Developing the 4CP will occur over three main phases of work, and there will be opportunities for public engagement in each round.
- Round 1 (Fall/Winter 2025): Confirm needs and prioritize streets for project development through the 4CP
- Round 2 (Winter/Spring 2026): Co-create project ideas and workshop design concepts
- Round 3 (Summer/Fall 2026): Finalize initial designs for priority projects and share the draft plan and implementation strategy
Get Involved
The 4CP will rely on extensive community engagement to confirm current priorities and co-create plan recommendations. Alameda CTC is partnering with local community-based organizations (CBOs) to reach historically underserved communities.
CBO partners for the 4CP include:
- Boys & Girls Clubs of San Leandro
- Cherryland Community Association
- Community Resources for Independent Living
- El Tímpano
- San Leandro 2050
There will be three rounds of public engagement opportunities, with the first beginning in November 2025.
We want to hear from you! Community voices are at the heart of the 4CP - your project ideas and priorities will inform the 4CP’s ultimate recommendations.
Please click here to take a brief survey and leave comments on an interactive webmap to help us confirm needs and prioritize streets for project development in future rounds of the 4CP. The survey and webmap will be open for public comment through December 31st, 2025.

Many of the communities in the 4CP study area have been heavily and disproportionately impacted by the extensive freeway and railroad infrastructure that divides central Alameda County. While many plans and studies have been done nearby over the years, the 4CP focuses on a narrow area that borders multiple jurisdictions to comprehensively identify and advance improvements across jurisdictions.
The 4CP will document community-identified projects through focused technical analysis and extensive stakeholder and public engagement, and develop initial engineering drawings and cost estimates to support the community’s highest priority projects. The final plan will summarize the 4CP planning process and recommendations, and be accompanied by an implementation strategy to ensure communities benefit in the near-term.
Alameda CTC is leading this effort in collaboration with Caltrans thanks to a Sustainable Transportation Planning Grant. Other key stakeholders include the cities of San Leandro and Hayward, the Alameda County Community Development Agency, Alameda County Public Works, AC Transit, BART, and the Hayward Area Recreational District.
Work began in early summer 2025 and will be complete no later than June 30, 2027, per grant requirements.
