Spawning Gravel Supply and Placement

The contract involves the supply and placement of 25,452 cubic yards of clean spawning gravel to establish 4.8 acres of low-gradient riffle complexes and gravel bars within the Tuolumne River floodway, aiming to enhance aquatic habitat for spawning species. The work is part of a broader effort to restore and improve riverine conditions in the region, with the gravel must meet strict quality standards to ensure suitability for fish reproduction and sustainable ecosystem function. The project is structured as a subcontract under the Central Valley Flood Protection Board, which oversees the initiative as part of California’s flood protection and environmental restoration objectives. Performance of the contract is localized to Turlock, California, and the work falls under NAICS code 327320, indicating classification within the crushed and broken stone manufacturing industry, consistent with the handling and processing of construction-grade gravel. The solicitation was posted on July 2, 2026, and the contract is intended to support long-term habitat recovery goals, with attention to environmental compliance and careful execution along the floodway to avoid disruption of existing ecological and hydrological patterns. No specific set-aside or eligibility restrictions are indicated, and the project will proceed under the oversight of the state agency with full accountability for material sourcing, placement accuracy, and habitat outcome.
