Page 2 of 4 Rebuilding American Infrastructure with Sustainability and Equity Grant The Infrastructure Investment and Jobs Act – Bipartisan Infrastructure Law authorized $1.5 billion to be awarded by the US DOT in fiscal year 2024 for local and regional project assistance grant programs; one such program is the RAISE grant. Similar to the prior federal BUILD and TIGER grant programs, RAISE is a multi-year capital and planning improvement program that allows for state, local, and regional agencies to invest in surface transportation to improve safety, economic strength and global competitiveness, equity, and climate sustainability. The application deadline for fiscal year 2024 is February 28, 2024. Sunol Interchange Improvement Project The I-680/Sunol Boulevard interchange is the city’s southernmost access to I-680 and experiences a high volume of morning peak hour traffic that causes recurring congestion along Sunol Boulevard and on I-680. The Sunol Boulevard ramp intersections also experience a high volume of broadside collisions. A modification to the interchange is necessary to improve safety and reduce congestion. The project will reconstruct the westbound to southbound loop ramp, including the bridge section, to allow for two lanes to enter I-680 southbound. The project will also make pedestrian and bicycle improvements along Sunol Boulevard and construct traffic signals at each of the ramps. Installation of traffic signals as part of the interchange project will improve safety and reduce accidents. The reconstruction of the loop ramp and bridge section will improve congestion and reduce the bottleneck that occurs on the freeway mainline. 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. This process includes four phases: 1. Project Initiation Document (PID)/Project Study Report (PSR) 2. Preliminary Analysis & Environmental Document (PA&ED) 3. Detailed Design 4. Construction The City completed the PID/PSR in 2020. Upon completion of the PID, work began on the environmental document, which is approaching final approval as a Mitigated Negative Declaration. DISCUSSION The I-680 at Sunol Boulevard Interchange Modernization Project makes significant improvements to Sunol Boulevard, the Sunol interchange, and I-680. The estimated total project cost for design and construction is approximately $31 million, which includes an anticipated $26.5 million in future construction costs. This project is identified in the City’s Traffic Impact Fee program, and the four-year CIP includes $6,627,212 in Traffic Impact Fee (TIF) funding for this project. Past approved funding and expenditures toward the design of this project total an additional $1,834,448 of TIF funds. Staff has pursued outside funding for project design and construction and was recently included in the 2024 STIP, with construction funding awarded in the amount of $6 million (available for appropriation in FY2027/2028). Additionally, approximately $890,000 in federal earmarks for construction are also pending approval. Page 146 of 228
