Ephemeral Stream Cobble Rock Removal

The contract involves the removal of large cobble rocks from a dry, ephemeral stream channel during periods when no water flow is present, with strict adherence to environmental regulations to ensure no discharge of sediments, debris, or other constituents into the waterway or surrounding ecosystem. Work must be conducted with precision to avoid disturbance beyond the designated area and to maintain compliance with regional water quality standards, particularly under the oversight of the Regional Water Quality Control Board, Region 5 - Redding. All activities are limited to non-flow conditions to minimize ecological impact and prevent unintended contamination. The project falls under NAICS code 238990, indicating it is classified as other heavy and civil engineering construction, and is structured as a subcontract. It was posted on July 7, 2026, with performance expected in California, though specific location details such as city or zip code are not provided. The contract emphasizes environmental stewardship, requiring all operations to be timed and executed in a manner that protects aquatic habitats and water quality, even in the absence of current flow. Compliance with state and regional regulatory frameworks is mandatory throughout the duration of the work.
