HDD Bore Hole Abandonment and Stream Restoration

This subcontract involves the abandonment of horizontal directional drill bore holes and the subsequent restoration of stream environments for PG&E utility projects located in Sonoma County, California. The scope of work requires filling and sealing bore holes beneath Salmon Creek and an unnamed tributary using specific grouting materials, followed by the restoration of the streambed and adjacent land to their original conditions through the application of soil and native vegetation. The project must be executed in strict accordance with the environmental compliance standards set by the California Department of Fish and Wildlife Bay Delta Region. The primary objective is the delivery of a fully sealed bore hole and a restored streambed that meets all regulatory requirements. This effort falls under NAICS code 562910 and is coordinated through the California Fish and Wildlife Region 3 agency in Fairfield.
