Geotechnical Investigations for the Sunset Weir and Pumps Fish Passage Project

Geotechnical investigations are planned along the right west bank levee and floodway of the Feather River to support the design of the Sunset Weir and Pumps Fish Passage Project, including the removal of Sunset Weir. Nine borings will be drilled to a maximum depth of 120 feet or to refusal, using a truck-mounted drill rig, with two of those employing Seismic Cone Penetration Test methods. Soil sampling will be conducted via Standard Penetration Tests, and all boreholes will be backfilled on the same day of drilling using cement-mixed cuttings delivered by tremie. Site preparation includes clearing and grubbing vegetation within the floodway, and all work will occur near the existing Sunset Weir structure, approximately 2.25 miles southeast of Live Oak in Sutter and Yuba Counties, California. The collected geotechnical data will inform engineering decisions for the fish passage project. The activity is exempt from full environmental review under California Environmental Quality Act Class 6 and Class 4 categorical exemptions. No formal contract value, pricing details, or delivery schedule are specified, and the procurement is currently in a forecast stage with no solicitation number assigned. The work is administered by the Central Valley Flood Protection Board with oversight from the Department of Water Resources. Key points of contact are Jordan Robbins, Senior Environmental Scientist, and Rachel Ballanti, Program Manager II. While the scope includes field drilling, sampling, and backfilling with no mention of shipping or packaging requirements, inspection and acceptance responsibilities are implied to rest with the government agencies involved. No formal contract clauses, evaluation factors, award criteria, special requirements, or offeror certifications are documented in the available materials. No payment office details, accounting codes, invoicing methods, or assigned contracting officer representatives are identified. The project lacks formal solicitation structure, indicating it may be in a pre-award phase where the focus is on environmental compliance and technical planning rather than competitive procurement under strict federal acquisition regulations.
