Culvert Installation and Streambed Crossing Construction

The contract involves the installation of a new culvert crossing over an ephemeral drainage, requiring full construction procedures including excavation, precise placement of the culvert structure, backfilling to ensure proper structural support and stability, and implementation of comprehensive erosion control measures to mitigate sediment runoff and protect surrounding land. All work must comply with environmental standards to prevent disruption to natural drainage patterns and minimize impact on local ecosystems during and after construction. This subcontract is issued by the City of Clearlake under the NAICS code 237990 for other heavy and civil engineering construction and is posted on July 2, 2026, with performance tied to a specific project location in California. The work is part of a larger infrastructure initiative identified by the project number 2018089031, and though no specific set-aside provisions or point of contact details are provided, the scope demands specialized earthwork and erosion management expertise to meet regulatory and safety requirements for streambed crossings.
