Dredging Operations Technical Support Program. Planning-Level Cost Estimates of Dredged Material Containment Islands in New York Harbor.

Abstract : Planning-level cost estimates are presented for each of three containment island configurations to be located in Lower New York Bay. Estimates are considered to be only 'order of magnitude' values based on typical unit prices for construction and operation of the assumed island configurations. Islands are limited to 500 acres including all dike boundaries. Sand dike, rock and sand dike, and sheet pile cofferdam designs are considered; cost estimates developed for each design and compared collectively. Keywords: Containment island alternatives; Containment island cost estimates; Dredged material containment island.
