Adopt resolution to designate the intersection of County Road 99D and Barry Road as a multi-way stop intersection; and authorize the Department of Community Services to install and maintain all necessary signs associated with the multi-way stop. (No general fund impact) (Fieseler/Riddiough)

Yolo County Board of Supervisors District 2 Staff requested that Public Works Division Staff evaluate the possible installation of a multi-way stop at the County Road 99D and Barry Road intersection. This request was based upon feedback from residents of the Binning Tract subdivision, just north of the City of Davis, who are experiencing difficulties exiting Barry Road onto County Road 99D, which has a speed limit of 55 miles per hour.  County Road 99D is an approximate two-mile-long road that connects County Road 29 to the City of Davis at Covell Boulevard (once in the city limits, its name changes to John Jones Road).

Public Works Division Staff gathered traffic data and available collision information for this intersection to help evaluate this proposal. The California Manual of Uniform Traffic Control Devices (CAMUTCD) describes three conditions where stop signs could be used and are listed below:

Public Works Division Staff found that none of the above conditions are met at this time to warrant stop signs, so installation of a multi-way stop under the current conditions cannot be supported by Public Works Division Staff.

However, the CAMUTCD also lists the following optional, albeit more subjective, criteria that can be considered by the approving body in determining whether to approve stop signs:

The optional criteria are provided for specific instances where the intersection does not meet engineering standards for the installation, but where there is interest by the approving authority in applying stop controls to address existing conditions. It was the interest of Supervisor Frerichs to address residents’ concerns about left-turn conflicts, and safe access for residents to walk and bike to the City of Davis for school and other services, with the installation of stop signs at this location.

Due to community feedback District 2 Staff have received over the past year, Supervisor Frerichs has requested that Public Works Division Staff bring this item to the Board of Supervisors for consideration. District 2 Staff believe the optional criteria related to controlling left-turn conflicts warrants the installation of stops signs on the north/south legs of the intersection.  A survey was presented to the community in 2024 and 30 of 54 households responded to the poll, with a majority supporting installation of a stop sign based on left-turn conflicts and other safety concerns.  A summary of the community survey results is included in Attachment C.

The Board of Supervisors has the authority to approve the installation of a stop-controlled intersection per the CAMUTCD optional criteria, specifically the criteria to help control left-turn conflicts.

There are tentative plans for a new shared-use bike path to be constructed between the Bretton Woods Subdivision just south of the Binning Tract Subdivision per Yolo County’s Agreement with the Bretton Woods developer.  The path is planned to run along the west side of County Road 99D from Bretton Woods Subdivision to just south of Barry Road.  Providing an all-way stop at the County Road 99D and Barry Road intersection would help address the expected higher bicyclist volumes that would need safe passage from the west side of County Road 99D to the Class II bike lane on the east side in order to continue a northbound trip toward County Road 29 on the correct side of the road (ride with traffic) once the path is built.

In addition, there is an existing church located at the northwest corner of the subject intersection.  The driveway access to the church parking lot along Barry Road is less than 200 feet away from County Road 99D.  Installation of a multi-way stop would improve traffic operations in this area during church activities.

If the multi-way stop is approved, prior to installation of the stop signs along County Road 99D, message boards would be placed advising motorists of the pending installation of stop signs. The installation of the stop signs will be completed within approximately two months of designating the intersection a multi-way stop. Completion of the installation process would be weather dependent, subject to the availability of construction materials, and follow the completion of the design, review, and approval of a revised striping and signage plan for the intersection, and as needed north and south of Barry Road on County Road 99D.
