Construct approximately seven new flood protection structures including dikes, berms and concrete/riprap ditches to divert flood waters away from the historic structures and visitor walkways at Scotty's Castle. The primary flood protection structure would be the reconstruction of an approximately 400-foot long gabion (rock-filled wire baskets) dike east of the Stables area in the main Grapevine Canyon channel. The previous washed out dike was constructed of native soil materials. In addition, in the two smaller washes immediately uphill of the Cook House and Stables, flood deposited sediments would be excavated, and a combination of concrete waterways and protective berms would be installed to carry storm flows around these historic structures. Dike construction is proposed as gabion-baskets, which is the typical flood protection dike structure installed in the area.
