AI Contract Overview

The project on San Pablo Avenue in Contra Costa County aims to transform the roadway into a Complete Street that safely accommodates drivers, pedestrians, and bicyclists between California Street in Rodeo and Pomona Street in Crockett. The existing four-lane configuration will be reconfigured to three lanes—one in each direction and a center lane designated for turning, merging, truck climbing, and as a buffer median where appropriate. This redesign will free up space for approximately 13,700 linear feet of a 10-foot-wide, physically separated shared-use path for pedestrians and cyclists, protected by a 3-foot buffer and concrete barrier. An additional 650 linear feet of Class II bike lanes will be added between Rodeo Avenue and Parker Avenue, requiring pavement widening, striping, drainage inlet adjustments, and new curb ramps. Along the north side of the avenue between Parker Avenue and California Street, 1,050 linear feet of new sidewalk will be constructed. Intersection improvements are planned, including enhanced striping, traffic signal timing adjustments, new curb ramps, Rectangular Rapid-Flashing Beacons, Pedestrian Hybrid Beacons, and concrete refuge islands. At least one WestCAT bus shelter may be relocated, and a stormwater bioretention facility is proposed at the San Pablo Avenue/Refinery Road intersection. New street lighting will be installed along the northern side of the corridor from California Street to Pomona Street, with excavations ranging up to seven feet for lighting foundations and utility pole relocations, or up to three feet for other components. Utility relocations, temporary traffic controls, vegetation removal, and real estate actions such as right-of-way acquisition or easements may be necessary to support construction, which is scheduled to begin in Fall 2027 and extend for at least one year, with work primarily during weekdays and potential nighttime operations but no weekend activity. Best management practices for stormwater control, including inlet protection, will be implemented in compliance with ADA, Caltrans, FHWA, MUTCD, and AASHTO standards. The project is being administered by Contra Costa County, with environmental compliance assured under CEQA categorical exemptions, and all work will be performed on-site along the designated corridor in unincorporated areas of the county.

Full Description

The purpose of this project is to improve San Pablo Avenue by converting it to a more accessible "Complete Street" for drivers, pedestrians, and bicyclists. Improvements will occur within the existing roadway between California Street in Rodeo and Pomona Street in Crockett. The roadway will be reconfigured from four vehicular travel lanes to three: one travel lane in each direction, and a center lane that will provide turning, merging, truck-climbing needs and a buffer median, depending on location. This change will create space to construct approximately 13,700 linear feet of a 10-footwide shared use path for pedestrians and bicyclists that is separated from vehicular traffic by a 3-foot-wide buffer and concrete barrier. Additionally, approximately 650 linear feet of new Class II bike lanes will be constructed between Rodeo Avenue and Parker Avenue. The new bike lanes will involve pavement widening and striping to allow for parallel parking, existing drainage inlet modification/relocation, and curb ramp construction. The project will construct approximately 1,050 linear feet of sidewalk along the north side of San Pablo Avenue between Parker Avenue and California Street. Intersection upgrades may include striping, pavement markings, traffic signal timing optimization, curb ramp construction/reconstruction, Rectangular Rapid-Flashing Beacon and Pedestrian Hybrid Beacon installation, and concrete passageway (refuge island) modifications. At least one Western Contra Costa Transit Authority (WestCAT) bus shelter may be relocated. A stormwater bioretention facility may be constructed at the San Pablo Avenue/Refinery Road intersection. Street lighting will be installed along the northern side of San Pablo Avenue between California Street and Pomona Street. An excavation depth of around seven feet is expected for the construction of street lighting foundations and relocation of existing utility or traffic signal poles. Otherwise, excavation of up to three feet is expected for other improvements. Utility relocations, temporary traffic control, and vegetation trimming and removal may be necessary to accommodate the project. Real Estate transactions, including right-of-way acquisition and easements may be needed. Construction is anticipated to start in the Fall of 2027 and last at least twelve months. While nighttime work may be needed to complete the project, work on weekends is not anticipated. Applicable best management practices will be implemented for water pollution control such as storm drain inlet protection.
