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 sediment transport route extends approximately 1.5 miles from the reservoir on the north to the sediment placement site on the south. 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. Sediment removal activities are anticipated to occur over two years from April through December of 2009 and 2010 (weather permitting). The removal of native vegetation in the sediment placement site is anticipated to occur during after September 2008 and prior to March 2009. The riser construction would likely occur from May to December 2009. Dewatering of the reservoir would occur before the riser construction and would last for approximately two weeks. The dry-out of the reservoir would start at the end of the dewatering cycle, which is anticipated to last up to three weeks, depending on the magnitude of recession flows and the weather.
