Sediment Removal in the Cantua Creek Channel and Harlan Drain Inlet
Document Type
NOE - Notice of Exemption

Document Description
The project consists of routine maintenance in the area between the terminus of Cantua Creek and the Aqueduct; this area allows floodwater and sediment to flow onto flood easements and enter the Aqueduct in a controlled manner and will return the area to design specifications. Without maintenance, sediment and vegetation will accumulate and cause floodwater to threaten the integrity of the Aqueduct. The project involves annually removing up to 7,500 cubic yards of sediment; any vegetation growing in the channel under four inches diameter at breast height will also be removed. In addition, the project will remove an unauthorized berm approximately 1,300 feet long and consisting of 4,800 cubic yards of sediment. Approximately 370 cubic yards of the sediment removed from the Creek channel or from the existing berm, will be used to create an approximately 100 feet long diversion berm, the remaining sediment will be placed in an existing spoil area south of MP 133.81R. This work benefits the State Water Project.
