Public Hearing: Route 4 Alignment Change

Notice of Public Hearing – Thursday, October 16, 2025 , 9:00 am

The Central Contra Costa Transit Authority (County Connection) will hold a public hearing to receive public comment on the following proposed changes to Route 4:

  • Change to the alignment to streamline route and improve reliability.
  • Increase to the frequency on weekdays to bus every 15 minutes.

Service Change Proposal

The Central Contra Costa Transit Authority (County Connection) is seeking public comment on proposed changes to Route 4 in Walnut Creek.

Alignment Change

County Connection is proposing a new alignment for the bus route to address existing issues. The changes are designed to streamline the route for more reliable service while still serving popular destinations. This involves leveraging existing pedestrian infrastructure to facilitate movement to and from bus stops and improving the stops themselves to meet current ADA standards in partnership with the City of Walnut Creek. Furthermore, stop locations will be optimized to balance spacing and utilize the Transit Signal Priority (TSP) system, ultimately improving on-time performance.

Frequency Change

County Connection is proposing increasing Route 4 bus frequency to every 15 minutes on Weekdays. County Connection partnered with the City of Walnut Creek and Resources for Community Development (an affordable housing developer) in applying to the State of California for an Affordable Housing and Sustainable Communities (AHSC) Grant for the Civic Crossing project, a new affordable housing development at 699 Ygnacio Valley Road. The grant was awarded in April 2024 and provides operating funds to increase frequency on Route 4 from every 20 minutes to every 15 minutes on weekdays from 7 a.m. to 9 p.m.

  • Re Proposed Route 4 change
    It looks like there will be NO BUS SERVICE to Whole Foods Market or Chase Bank or Safeway. If this is the case I’m not in favor.

    RE BIRD POOP IN WALNUT CREEK BART: Pigeon Poop is widely known to carry and transmit 26 Human Diseases easily, and hence it is always safe to stay away from them. The pathogens from dried droppings usually cause flu, fatigue, headache, fever, diarrhea, and dry cough, which is even more dangerous to weak immune humans. Can cameras & one person available all day to stop people from dumping bird food on the cement walkway be used to stop this. Who wants to sit for an hour and breathe or walk or see bird poop? First this pile was at one bench, now there’s patches of dried bird poop almost to the end of the bus middle walkway. I catch the #1 going toward Shadelands and sometimes the #93 . This is DISGUSTING ! I eat a sandwich, etc. but I do NOT leave any mess. I put trash in the garbage.

    I respectfully ask that something is done about this by whatever Agency possible.
    THANK YOU

    • Thank you for your feedback. The decision to simplify the route was made to allow us to run buses more frequently and reliably throughout the day. While the route won’t stop directly at the locations mentioned, it is still conveniently located less than a quarter-mile from the designated Rt 4 bus stops on Main St and Bothello and current Rt 5, 21 and 321 stops on Newell Ave. Our focus is on providing a dependable and frequent schedule that benefits the greatest number of riders while benefitting from good pedestrian infrastructure downtown.

    • We have forwarded your concern about bird guano to BART as they maintain the Transit Center.

  • 15 min frequency (or better) is essential! The primary reason I do not use route 4 more often is that it often would take longer to use for route 4 to get from WC BART to downtown than just walking.
    Any sacrifices in route coverage needed to acheive 15 min (or better) headways is worth the tradeoff.
    I would say that extending the route to Kaiser Med Ctr would be useful, but the headway improvement is more important.

    • We appreciate you reaching out with your feedback. While we realize the route simplification is a change, our primary goal was to establish a more consistent and frequent service. We had to make adjustments based on the current realities of our budget and available resources, like our fleet and operators.

  • Before you change this, please do some data collection on how many Las Lomas students use the 4 to get between Walnut Creek BART and Las Lomas. There are A LOT of Las Lomas students who use those stops on Newell to get on/off the 4.

    • We appreciate you reaching out with your feedback. While we realize the route simplification is a change, our primary goal was to establish a more consistent and frequent service. We had to make adjustments based on the current realities of our budget and available resources, like our fleet and operators. Students at Las Lomas will continue to have direct access via Route 5 (Free) and Route 21.

    • Thanks for the feedback. Direct service to Kaiser will remain available. On weekdays, riders can use Routes 5 (Free) and 21. On weekends, Route 321 will provide service.

  • Changing to every 15 minutes makes me happier, reducing my wait time.
    Still not happy about the 99X not having a stop near my office. That would make my commute even easier.

    • We’re glad the shift to every 15 minutes on Route 4 will be a positive change for you. Thanks for the positive feedback on the Route 4 change. To investigate your request for a new 99X stop, please reach out to us via email with the specific location.

      • I would like to see it continue to go down N California Blvd to Civic Drive as there are a lot of residents in that area on or right next to N California Blvd who use those stops. Also I think it should go all the way to Newell Ave to accommodate people going to locations in that area. I love the app that shows arrival times and make plans based on that and it’s very reliable.

We had to make adjustments based on the current realities of our budget and available resources, like our fleet and operators. California Blvd is served by Routes 1, 5 (Free) and 21 directly on Weekdays and Route 321 on weekend.

    • Thank you for your feedback. The decision to simplify the route and utilize the stops on Main St. was made to allow us to run buses more frequently and reliably throughout the day. While the route won’t stop directly at the store, the Safeway is still conveniently located less than a quarter-mile from the designated bus stops. Our focus is on providing a dependable schedule that benefits the greatest number of riders.

  • Service is very much diminished on the new route. I think it should continue to run near the Safeway and Whole Foods. Important to be near groceries stores

  • I use the #4 bus because the last bus is later than other buses (like the 21). I would appreciate more frequent operation

    • Thank you for your feedback. Hope the new change with more frequency on Route 4 works for you.

  • This is great, a more frequent bus would be good for my family. Also, the later bus is good. We need as many buses as possible 🙂
