Document Description
The Operator proposes to alter the streambed and banks through the repair and upgrade of an existing maintenance access road which has severely eroded in past storm events. The access road is used by County maintenance crew. Two locations along the levees of the San Gabriel River were severely scoured, approximately 750 feet by 50 feet of the left bank upstream of Rubber Dam No. 3, and 1,100 feet by 35 feet of the right bank downstream of Rubber Dam No. 3 were damaged and are in need of repair. The proposed project involves restoring the scoured levees back to pre-storm conditions. The restoration area of the two sites totals approximately 1.75 acres. Heavy equipment such as loaders and bulldozers will be used to repair the eroded levees using onsite material. Approximately 12,700 cubic yards of material will be redistributed and the entire project impact area will be 4.42 acres. If necessary, Public Works will import material from recent debris basin cleanouts to complete the levee repair project. Public Works will avoid impacts to the protected vegetated polygons within the channel during the levee restoration. The vegetated polygons within the impacted area will be protected by grading and forming sand islands around them.
