In-Channel Construction and Earthwork

The contract involves the execution of all in-channel earthwork activities including gravel placement, grading, and the formation of riffle complexes, to be carried out during the low-flow season using temporary access routes. These operations are designed to support ecological restoration and stream channel enhancement while minimizing environmental disruption by timing work in alignment with seasonal water conditions. The work is scoped to occur in Turlock, California, with all activities confined to the channel environment and reliant on carefully planned temporary infrastructure to access the site without permanent alterations. This is a subcontract under the NAICS code 237990 for other heavy and civil engineering construction, issued by the Central Valley Flood Protection Board of California. The solicitation was posted on July 2, 2026, and the project is part of broader flood protection and habitat rehabilitation efforts in the region. Performance is tied to strict seasonal constraints to ensure compatibility with aquatic life cycles and water availability, and the contractor is expected to manage logistics, materials, and equipment to meet technical specifications without reliance on permanent access points or extended site occupation.
