Book Description
The Craney Island Management Plan was developed to extend the life of the Craney Island Dredged Material Management Area (CIDMMA). The CIDMMA is used to dispose maintenance and new work dredged material from the project area. With current practice, CIDMMA would reach ultimate capacity by the year 2000. If, however, suitable material is barged to the sea and only contaminated material is placed in the facility (Restricted Use Program), then the life of the facility can be extended. Two tasks were addressed in this study: (a) determine service life under Restricted Use and (b) determine contaminant losses and conduct a Comprehensive Analysis of Migration Pathways (CAMP) expected to occur under Restricted Use. The results showed that the service life of the CIDMMA could be extended under Restrictive Use for approximately 140 years under baseline coniditions or 90 years under Worst Case conditions. The CAMP analysis was conducted along three major contaminant migration pathways (effluent, leachate, and volatile). Effluent was the most significant pathway for metal losses and volatilisation and for polynuclear aromatic hydrocarbon (PAH) losses. Leachate losses under a fully dewatered condition would not exceed effluent losses for some metals. PAH losses for a fully dewatered condition would not exceed effluent losses.

Book Description
The Craney Island disposal ara is a 2,500-acre confined dredged material disposal facility located near Norfolk, VA. In 1981, the Craney Island Management Plan (CIMP) was developed to extend the useful life of the site for disposal of maintenance material from the project area. The CIMP called for subdivision of the site into three subcontainments and use of alternating filling and dewatering cycles. Management of the site in general accordance with the CIMP was implemented in 1984. This report documents site operations and monitoring data for the Craney Island disposal area from Oct 1980 to Sept 1987. Field sampling operations, laboratory testing, and monitoring and survey data are described and interpreted. Based on the monitoring data collected to data and projections of future fill rates, the site will be filled to elevation +30 ft during FY 2000 if the present intensity of management is continued. If the site had not been subdivided and management for dewatering not initiated, the site would fill during FY 1997. Therefore, the CIMP as implemented to date will result in a gain in useful life of approximately 3 years or 2% of the remaining capacity. Differences are due to a combination of factors, including inaccuracies of models in projecting long-term fill rates, inefficiencies in implementing the CIMP, natural inefficiencies of desiccation processes, and the placement of significant volumes of new work material in the site.

Book Description
Is there an allure of spoiled places? Spoil islands are overlooked places that combine dirt with paradise, waste-land with “brave new world,” and wildness with human intervention. Although they are mundane products of dredging, these islands form an uninvestigated archipelago that demonstrates the potential value and contested re-valuation of landscapes of waste. To explore these islands, Spoil Island: Reading the Makeshift Archipelago navigates a course along the U.S. east coast, moving from New York City to Florida. Along the way, a general populace squats, picnics, and reflects on the islands, while other forces are also at work. New York City parks commissioner Robert Moses first deplores then adopts Hoffman and Swinburne Islands, UN Secretary General U Thant meditates on the East River’s Belmont Island, businessman John D. MacArthur rejects the purchase of Peanut Island, artist Christo surrounds Miami’s spoil islands, Key Westers debate the futures of two spoil islands that mark their sunset view, and artist Robert Smithson augments this archipelago materially and conceptually. Historical and contemporary stories highlight each island’s often contradictory ecologies that pair nature with infrastructure, public concerns with private development, rationalized urbanism with artistic impulse, and order with disorder. Spoil islands put you in places you normally wouldn’t—and perhaps shouldn’t—be. To examine these marginalized topographies is to understand emergent concerns of twenty-first-century place-making, public space, and natural and artificial infrastructure. Today, spoil islands constitute an unprecedented public commons, where human agency and nature are inextricably linked. Spoil Island will be of interest to anyone working in the areas of architecture, cultural history, cultural geography, environmental studies, or environmental philosophy. Linking the islands with their environmental aesthetics, Charlie Hailey provides a lively and critical topography of places that play a part in current events and local situations with global implications.
