BACKGROUND The I-680/Sunol Boulevard interchange is the city's southernmost access to 1-680 and experiences a high volume of morning peak hour traffic that causes recurring congestion along Sunol Boulevard. A modification to the interchange is necessary to improve safety and reduce congestion. Local interchange improvements, although located in Caltrans right-of-way, are always funded by the local agency. Any improvements to the interchange must be completed through the Caltrans project development process. In early 2018 the City issued a request for proposal for a consultant to complete a feasibility study and PID. Within the request was the option of extending the contract to include the PA&ED phase as well as final design and construction support (phases to occur after the PA&ED phase). On April 19, 2018, the City of Pleasanton entered into a contract with AECOM to prepare Project Initiation Documents (PID) commonly called a Project Study Report — Project Development Study (PSR-PDS). In late January 2020, Caltrans approved the PSR-PDS so that the project may enter the next phase of the Caltrans process: Project Approval & Environmental Documentation (PA&ED). DISCUSSION The PA&ED is a more detailed investigation into the impacts of the potential project alternatives. This phase also begins preliminary engineering and completes the environmental documentation needed for Caltrans approval. Like the PSR-PDS phase, the City will partner with Caltrans during the development of the PA&ED to expedite their review and approval. AECOM has extensive experience with the Caltrans project development process and has completed the Caltrans project approval phase for several freeway interchange projects in the greater Bay Area. In addition to their work on the Sunol Interchange PID, AECOM is performing PA&ED services for the 1-680 Express Lane (SR-84 to Alcosta Boulevard) on behalf of the Alameda CTC. This is advantageous for the City, as much of the data and area investigation from Alameda CTC's project can be used on the I- 680/Sunol Boulevard Interchange Project. Given their satisfactory performance on the PID phase, and extensive relevant experience, staff recommends AECOM complete the PA&ED phase of the project. Schedule Timeline for completion: • PSR-PDS - April 2018- Jan 2020, completed • PA&ED - June 2020- July 2021 • Detailed Design (Plans Specifications & Estimates) — July 2021-June 2022 • Right-of-Way — June 2022-December 2022 • Construction — February 2023-June 2024 Page 2 of 3
