West Las Positas Blvd Multimodal Reconstruction Project – Phase 2

The City of Pleasanton is undertaking the West Las Positas Blvd Multimodal Reconstruction Project Phase 2, which involves the reconstruction of a 0.52-mile segment of roadway between Stoneridge Drive and Fairlands Drive. The primary objective is to enhance safety, connectivity, and drainage by reducing the roadway capacity from a 6-lane or 8-lane section to a 4-lane section. Key improvements include the application of a hot mix asphalt overlay, the installation of 5- to 9-foot-wide elevated bike lanes and Class IV bike lanes, and the creation of landscaped buffers with bioretention features. Additionally, the project will implement intersection safety upgrades such as protected intersections, high-visibility crosswalks, and modified curb ramps to ensure full compliance with the Americans with Disabilities Act. The scope also encompasses the relocation of existing utilities and upgrades to street lighting, traffic signals, and bus stops. Construction is anticipated to span approximately 12 months, beginning in the first quarter of 2027 and concluding in the first quarter of 2028. The project is classified as a Class 1 Categorical Exemption under CEQA Guidelines Section 15301(c) for existing facilities. Strict adherence to MRP Provision C.C6 for construction site control and Best Management Practices to prevent sediment contamination is required. Furthermore, the contract mandates specific protocols for the discovery of archaeological resources, requiring the immediate cessation of work within 50 feet of any find and evaluation by a qualified archaeologist and Native American representatives if prehistoric resources are identified. Material storage is restricted to at least five feet from public streets per municipal code.
