Hamilton Avenue Capacity Upgrades (SD-25000) Project

The Hamilton Avenue Capacity Upgrades Project involves replacing the existing storm drain system along Hamilton Avenue, which currently features pipes ranging from 12 inches to 21 inches in diameter, with a more robust dual storm drain system consisting of 24-inch, 36-inch, and 48-inch pipes. The project also includes installing a new 36-inch storm drain segment on Center Drive, extending from Hamilton Avenue toward Dana Avenue. An optional scope proposes upsizing the existing 12-inch line to 36 inches on Alester Avenue. Key improvements encompass installing catch basins, manholes, junction boxes, gate valves, and performing modifications to existing infrastructure, along with trench restoration, CCTV inspections, and various surface work such as signing, striping, tree trimming, and concrete repairs. The contractor is responsible for planning and executing traffic control, dewatering, and logistical arrangements. The project's estimated cost is approximately $6.7 million, with a response deadline of August 15, 2025. The solicitation, identified as IFB195264, was posted on July 25, 2025, by the California Public Works-Engineering Services under the NAICS code 561730. The contract size ranges from $5 million to $10 million, and the primary point of contact is Nanette O'Brien, reachable via email or phone. The project aims to significantly enhance stormwater capacity and infrastructure resilience along Hamilton Avenue and adjacent streets, ensuring improved drainage and system reliability across the area.
