The Craney Island disposal area 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 October 1984 to October 1989. Updated projections of filling rates are also presented. Based on the monitoring data collected to date and projections of future fill rates, the site will reach full capacity in FY99 if the present intensity of management is continued. Because of the larger area and lower average elevation of the center cell, it is recommended that the future filling schedule be revised so that more material is placed in this subcontainment, and less in the north cell which has the highest elevation and smallest area.
