Yuba Gravel Placement

The Yuba Gravel Placement contract, solicited under number W9123826QA014, is a 100% Small Business Set-Aside under NAICS code 237990, issued by the U.S. Army Corps of Engineers’ W075 Endist Sacramento office, with the Department of Defense as the overarching agency. The project aims to restore aquatic habitat in the lower Yuba River’s Englebright Dam reach by placing approximately 5,000 short tons of suitable-sized spawning gravel (0.25 to 5 inches in diameter) to support the recovery of Central Valley spring-run Chinook salmon and Central Valley steelhead, as mandated by a National Marine Fisheries Service Biological Opinion under the Endangered Species Act. Work must be conducted between July 15 and September 1 each year using a sluicing method that injects a gravel-water slurry through 8-inch flexible piping into the river channel. The contract includes a base period from July 1, 2026, to June 30, 2027, with four one-year option periods extending through June 30, 2031, each requiring the same volume of gravel placement, water truck standby, and accident prevention plan delivery. Optional line items allow for the purchase of additional road repair materials. The contract is awarded on a Lowest Price Technically Acceptable basis, where technical acceptability is determined by a mandatory pass/fail gate requiring proof of ownership or immediate access to specialized equipment for gravel injection via 8-inch flexible piping. All proposals must comply with stringent environmental, safety, and security standards, including EM 385-1-1 safety protocols, AT Level 1 antiterrorism training, NCIC-III and TSDB vetting for unescorted DoD site access, and compliance with MIL-STD-130 and MIL-STD-129 for item identification and shipping labeling. Contractors must provide proof of insurance coverage—$1 million general and automobile liability, and $100,000 per employee worker’s compensation—before starting work. Invoicing is performed in arrears to the U.S. Army Corps of Engineers Finance Center in Millington, Tennessee, and requires verification by the Contracting Officer’s Representative prior to payment, with final payment contingent upon full completion of work, removal of all materials, and submission of all required reports.
