capping operations performed by the Great Lakes Dredging Company and the technical 

 support provided by SAIC aided NED in forming a stable CAD mound with a diameter of 

 550 m, a height of 2.5 m, and a CDM to UDM ratio of 0.96 to 1.0. 



The successful completion of the NHAV 93 mound represents the end of a ten-year 

 dredging cycle in the central Long Island Sound region. NED estimates that major 

 maintenance dredging of New Haven Harbor must be conducted every ten years to provide 

 adequate water depths for commercial, military, and private vessels utilizing the harbor. 

 Thoughtful management of smaller volumes of dredged material over the last decade not only 

 facilitated the safe disposal of over a million cubic meters of dredged material, but also 

 demonstrated a management strategy that can serve to maximize the site capacity of CLIS as 

 well as other DAMOS disposal sites.
