The duties of the Transportation Planning Section include reviewing development applications for traffic impacts, conducting or participating in transportation studies (multimodal, traffic impact, transit, etc.) tracking and advising on transportation legislation and policy and engaging transportation issues in the unincorporated areas of Contra Costa County.
I-680/Treat Blvd Bicycle & Pedestrian Improvements
The proposed project would provide a plan that identifies improvements to serve bicyclists and pedestrians using the Treat Boulevard/I-680 corridor between the Iron Horse Trail, through the Interstate-680 (I-680) over-crossing ("over-crossing") near the Contra Costa Centre/Pleasant Hill BART station area, and extending west to Geary Road/North Main Street in the City of Walnut Creek. The I-680/Treat Boulevard over-crossing is one of the main arteries into the Contra Costa Centre/Pleasant Hill BART station area from areas of Walnut Creek west of the freeway.
Iron Horse Corridor Active Transportation Study
This Study will explore opportunities and constraints for further developing the active transportation features within the Iron Horse Corridor. Contra Costa County ("County") will be the lead agency on the Study. However, the Study will be developed collaboratively and include stakeholders such as the cities (Concord, Pleasant Hill, Danville, Walnut Creek, San Ramon), East Bay Regional Park District, Contra Costa Transportation Authority, utility companies and advocacy organizations. The Study will include an extensive public outreach component, existing conditions analysis, transportation analysis and alternatives development and analysis.
Marsh Creek Corridor Multi-Use Feasibility Study
The proposed Marsh Creek multi‐use trail would create a new major non‐motorized east‐west thoroughfare for expanded commuting or recreational opportunities. It would provide non-motorized access to Downtown Clayton, Diablo View Middle School, Mount Diablo, Round Valley Regional Reserve, and the existing Marsh Creek Trail through Brentwood and Oakley.
Senate Bill (SB) 743
In 2013, Governor Brown signed Senate Bill (“SB”) 743 (Steinberg), which creates a process to change the way that transportation impacts are analyzed under California Environmental Quality Act (“CEQA”). June 23, 2020, the Contra Costa County Board of Supervisors adopted Transportation Analysis Guidelines to aid in the preparation of traffic analysis for project applicants and staff.
WCCTAC Program Update
WCCTAC first implemented a transportation impact fee via the Subregional Transportation Mitigation Program (STMP) in 1997 and has conducted an update of the fee program this year, in 2019. The fee helps fund transportation projects to mitigate the impacts of new development. Per Assembly Bill (AB) 1600, the Mitigation Fee Act, this website hosts documents required to meet public noticing requirement.
