Contra Costa County Public Works Department (County) proposes pedestrian crosswalk safety enhancements to improve pedestrian safety and increase driver awareness at an existing uncontrolled crosswalk. Uncontrolled pedestrian crossings are a safety concern because drivers tend to be traveling at a higher rate of speed versus a stop or signal-controlled crosswalk. This particular crosswalk was chosen due to close proximity to schools, safety data, and limited line of sight for pedestrians and drivers. The County proposes the following safety enhancements: double-sided rectangular rapid flash beacons (RRFBs) with pedestrian actuated buttons at both ends of the uncontrolled crosswalk, Americans with Disabilities Act (ADA) compliant curb ramps with detectable warning surfaces where feasible, a pedestrian refuge island in the center of the crossing, and curb extensions/bulb-outs to reduce crossing distance for pedestrians. Existing signage and striping that may be in conflict with new improvements may be removed and replaced. The addition of new advanced warning signs and striping including yield bars is anticipated. These safety enhancements will increase driver awareness and reduce pedestrian exposure to limited line of sight of oncoming traffic. Drainage facilities will be adjusted to the new improvements; one new inlet is proposed. Ground disturbance and excavation to a maximum depth of approximately 8 feet is anticipated for the new drainage inlet. Real estate transactions, utility relocations, and vegetation trimming/removal may be necessary. Construction is anticipated to occur in 2024, take approximately 30 working days to complete, and occur during the summer to minimize impacts to the surrounding school zone. Temporary traffic controls will be implemented during construction activities; emergency vehicles will have access at all times. Appropriate best management practices for stormwater control (i.e. storm drain inlet protection) will be in place during construction.
