2022-2024 Sites Reservoir Geologic, Geophysical, and Geotechnical Investigations Draft Environmental Assessment/Initial Study
MND - Mitigated Negative Declaration
Present Land Use
Exclusive Agriculture, Agriculture/Forestry
The Sites Project Authority and the Bureau of Reclamation are proposing to conduct geologic, geophysical, and geotechnical investigations (investigations) in Glenn, Colusa, and Yolo Counties. These investigations are intended to provide technical information to assist in the ongoing efforts to formulate and refine the engineering design and to assist in the preparation of permit applications for the proposed Sites Reservoir and its associated facilities in western Sacramento Valley. The Proposed Action Area generally includes the areas in and near the Antelope Valley in Colusa and Glenn Counties where the dams, reservoirs, pipelines, and related facilities could be located for the proposed Sites Reservoir, along with areas near the town of Dunnigan in Yolo County where pipelines and related facilities could be located for the proposed Sites Reservoir. Three types of investigations are planned, and include surface geologic investigations, surface geophysical investigations, and subsurface geotechnical investigations.
