About this opportunity
The U.S. Army Corps of Engineers (USACE) is seeking a contractor to execute a gravel augmentation project on the lower Yuba River in California, specifically in the Englebright Dam Reach. The project is mandated by a Biological Opinion from the National Marine Fisheries Service and aims to rehabilitate aquatic habitat for anadromous salmonids by placing a heterogeneous mix of gravel and cobble into the river channel. The primary objective is to improve ecological functionality and create suitable spawning conditions for Central Valley spring-run Chinook salmon and Central Valley steelhead in their critical habitat. While specific evaluation criteria are not detailed in the pre-solicitation notice, the contract will likely prioritize technical capabilities to execute precise riverbed gravel placement. The pre-solicitation was posted on March 31, 2025, with a response due date of June 3, 2025, indicating potential contractors have approximately two months to prepare their submissions.
The contract is designated as a total small business set-aside, meaning only small businesses can compete for this opportunity. The project will be located downstream of Englebright Dam in Yuba County, California, covering a river segment approximately 23 miles east of Marysville. The NAICS code 237990 for Other Heavy and Civil Engineering Construction suggests the work involves specialized environmental engineering and river restoration techniques. The PSC category of 5610 (Mineral Construction Materials, Bulk) further indicates the technical nature of the gravel placement requirements. While specific budget details are not provided, the complexity of the ecological restoration project and the precise geological specifications suggest this will be a specialized and potentially significant contract for the right small business contractor with environmental engineering capabilities.
Notice text
This project is being performed as a requirement of a Biological Opinion issued by the National Marine Fisheries Service (NMFS). The U.S. Army Corps of Engineers (Corps) is proposing to continue a gravel augmentation project which involves placement of a heterogeneous mix of gravel and cobble into the lower Yuba River channel below Englebright Dam.
The purpose of gravel augmentation is to place suitable-sized spawning gravel within the upper Narrows reach for rehabilitating associated geomorphic processes and aquatic habitat in the Englebright Dam reach of the Lower Yuba River. Implementation of a long-term augmentation program will serve to improve the overall ecological functionality of the channel. The project will provide gravel and cobble suitable for anadromous salmonid adult spawning, embryo incubation, and survival to emergence in a key area in the lower Yuba River designated as critical habitat for the Central Valley spring-run Chinook salmon and the Central Valley steelhead. The project area is located on the lower Yuba River downstream of Englebright Dam (Yuba River mile 23.9), Yuba County, California (Plate 1). Gravel augmentation will be confined to the river channel located between Englebright Dam and the junction with Deer Creek. This reach is called the Englebright Dam Reach and it is located in the steep canyon off Highway 20, about 23 miles east of Marysville, California.
