Bicycle, Pedestrian & Trails Committee Agenda Report July 24, 2023 SUBJECT: WEST LAS POSITAS MULTIMODAL RECONSTRUCTION PROJECT CONCEPT PLANS SUMMARY The city is working on improvements to the West Las Positas Corridor between Foothill Road and Santa Rita Road to improve pedestrian and bicyclist circulation and provide safety enhancements throughout the corridor as identified in the 2018 Bicycle and Pedestrian Master Plan. The project also addresses the uneven roadway pavement surface as directed by the City Council in 2021. These two high priority projects were combined into a single project titled “The West Las Positas Multimodal Reconstruct Project”. The pedestrian and bicycle components of the West Las Positas Multimodal Reconstruction Project were developed with extensive public input and en dorsed by the Bicycle, Pedestrian and Trails Committee in December 2019 and by City Council in 2022. On November 15, 2022, City Council authorized staff to further develop plans for West Las Positas up to a 35% construction plan level. Two concept plans have been developed to aid in the development of the 35% construction plans. Concept Plan Alternative 1 will include an interim condition with use of “quick built elements” such as added striping and plastic delineator posts to establish a Class IV cycle track. Alternative 1 improvements will reside within the existing roadway cross section and will maintain the existing sidewalk, curb and gutter, median curb, and include the following: • Maintain improvements within the existing right of way. • Rehabilitate or reconstruct pavement per the geotechnical analysis and recommendations. • Provide protected intersections and crossing treatments for bicycles and pedestrians at existing signalized intersections using pavement markings and delineators. • Incorporate green colored pavement markings to help delineate bicycle infrastructure. • Upgrade and reconstruct ADA curb ramps and driveways where pavement reconstruction impacts existing conditions. • Provide spot repairs and replacements for existing wet utilities, including existing stormwater, sewer, and water laterals. • Modify crosswalk aesthetics between Hopyard Road and Stoneridge Drive with colorized stamped asphalt concrete with brick patterns.
