AI Contract Overview

Show more

The California Department of Water Resources is forecasting a project for geotechnical investigations as part of the Sunset Weir and Pumps Fish Passage Project. Located in Live Oak, Sutter County, the work involves performing nine geotechnical explorations along a reach of the Feather River, specifically within the river channel, along the levees, and near the existing Sunset Weir Pump Station. The primary objective is to collect essential data to assess riverbank stability in response to predicted water surface elevation changes caused by the proposed removal of the Sunset Weir. This information will support the development of bank protection measures and provide necessary geotechnical recommendations for the design of a new pump station and new intake structures. The investigations are anticipated to take place in 2025, contingent upon receiving necessary regulatory and permit approvals. The scope of work is estimated to last approximately 30 working days, with typical working days lasting about 12 hours. Due to environmental considerations, in-water geotechnical sampling is restricted to a specific seasonal window from July 15 to September 30. While the project has undergone environmental review processes, including the adoption of a Notice of Exemption under the California Environmental Quality Act, specific contract details such as the total estimated value, contract type, and formal solicitation number are not currently specified.

The Project would involve performing nine geotechnical explorations to collect information needed to assess the stability of the Feather River riverbank in response to predicted changes in the water surface elevations that would be produced by the proposed removal of Sunset Weir and thus support the development of potential bank protection measures. The geotechnical investigations would also collect information needed to provide geotechnical recommendations for the design of a new Sunset pump station and new intake structures.
