Document Description
The project involves the raising of a 2, 700-foot section of the Huff's Corner levee system by 4 to 6 feet to restore the levee to its original 1957 design profile, which includes 3 feet of freeboard. To accomplish this required elevation, the levee base will be widened on the landside by approximately 12 to 15 feet. The project will include a revised Operations & Maintenance easement corridor extending an additional 15 feet beyond the new landside toe of the levee. The project also entails the removal of a vegetated island that has accumulated adjacent to the levee within Lower Cache Creek. Sediment from this island will be removed and hauled off-site from the left-side secondary creek channel. Vegetation that is currently stabilizing the midchannel island will also be removed. A sacrificial terrace will be constructed along the right bank, which will reduce flow velocity against the bank and the levee, and direct creek flow towards the center of the channel. Both components of the project are scheduled to be constructed concurrently in 2022. The project will also involve some pre-construction activities in 2021, such as vegetation removal, general site preparation, and utility relocations, in advance of major construction activities once proper approvals and permissions have been secured.
