Document Description
The proposed project consists of draining the Santa Anita Reservoir, removing sediment and debris from the reservoir by dry excavation, transporting the sediment from the reservoir (via conveyor belt and truck), and placing it in an existing sediment placement site. The proposed project would remove ~300,000 to 500,000 cubic yards of sediment from the reservoir. The proposed project also includes improvements to the Santa Anita Dam, which would involve modifications to the dam's inlet/outlet works, including the construction of a new riser.
