The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement number 1600-2017-0270-R2, pursuant to Section 1602 of the Fish and Game Code to Surjeet Bains.
The proposed project will repair the existing levee that was damaged during 2017 high flows. The proposed project will fill eroded areas with clean clay fill and then cover the areas with rip-rap. The rip-rap will be paced to match the existing levee slopes. On-site native soils will be savaged and they will be used to cover the newly placed rip-rap. Exposed spills will be stabilized and planted with local native vegetation. These activities will occur at two locations adjacent to each other. One location is approx. 300 feet by 50 feet and the other location is approx. 200 feet by 40 feet. Approx. 1,200 cubic yards of clean clay fill and 1,000 ton of ¼ ton and 18-inch rocks will be used to complete this project. All access will be performed through an existing levee road and only one cottonwood over 4-inch diameter at breast height will be impacted during construction activities. All work will occur within dry areas of the Feather River and no water diversion will be required. All staging areas will be placed outside the active floodplain.
On Feb 12, 2017, the Governor signed an Emergency Declaration for the emergency caused by the erosion of Lake Oroville's spillway. Governor's Executive Order B-39-17, dated April 6, 2017 suspended CEQA and any regulations adopted pursuant to CEQA for any action necessary to expedite the recovery of the spillway and related infrastructure resulting from activities related to the lake Oroville Dam gated Spillway Emergency. The proposed project will restore a levee that was damaged during the high flows that occurred in 2017 that triggered the emergency declaration and executive order B-39-17.The project is limited to one encroachment to repair an existing levee by reinforcing the slough side of the levee with 180 cubic yards of clean rock riprap. All work will take place within the original footprint of the levee where a deteriorating redwood timber wall previously provided bank protection. All work on the lower portion of the slough side of the levee will take place at low tide in order to minimize impacts to water quality and aquatic resources.
