A 183 m by 122 prefabricated vertical-drain test section was completed in February 1993 in the Craney Island Dredged Material Management Area. The test section was constructed to evaluate the effectiveness of prefabricated vertical drains in consolidating the dredged fill and underlying foundation clay, thus increasing the storage capacity of the facility. The feasibility of installing prefabricated vertical drains was questionable because vertical drains had never been installed in an active dredged material management area.
