The proposed project would include removal of sediment from the Tisdale Bypass, which is located at Sacramento River Mile 119 in Sutter County, about 6.3 miles downstream of the community of Grimes and 10 miles upstream of the Yolo County/Colusa County line to bring the channel back to its design capacity. The proposed project would use heavy construction equipment to remove sediment from the Tisdale Bypass. and involve staging and mobilizing equipment, clearing, mowing and removal of trees and shrubs and removal of sediment from the Bypass and depositing soil within the disposal site northwest of the Bypass North Levee and Reclamation Road intersection on the Sacramento and San Joaquin Drainage District’s parcels. The proposed project would excavate up a net removal of 400,000 CY from the bypass. The sediment excavated from the bypass would be hauled by scrapers up two temporary constructed ramps, over the North Levee, and hauled and deposited onto the Sacramento and San Joaquin Drainage District’s parcels. When the sediment removal is completed, the temporary ramps over the levees would be removed and the levees returned to pre-project conditions. Project construction would occur from August 15, 2020 to October 31, 2020.
