Collapse All Expand All

The North Atlantic Division Regional Center of Expertise for Deep Draft Navigation is based in the New York District and provides interdiscliplinary professionals with expertise in implementing environmentally sustainable Deep Draft Navigation projects. Mission areas supported include Navigation, Operations and Maintenance, Regulatory, Civil Works, Environmental Restoration, IIS Support for Others.

Our Expertise Includes:

  • Plan formulation of channel deepening projects
  • Use of economic models to optimize challen improvements
  • Design vessel selection/ship simulation modeling
  • Hard bottom channel design/Rock dredgin
  • Environmental analysis of dredged material
  • Air mitigation
  • Dredged material placement site management
  • Beneficial use of dredged material
  • Island restoration using suitable dredged materials
  • Hydrographic surveying
  • Ecosystem restoration economics for dredged material
  • Treatment and utilization of processed dredged material
  • Interagency coordination/regional dredging teams

Throughout the years, the shipping industry has created wider ships that require deeper drafts to enable them to transport the maximum amount of goods in the most efficient manner. Today, this new generation of ships requires shipping channel depths in excess of 45 feet. The Army Corps, as authorized by the United States Congress, works with its port authority partners to meet industry demands in a safe and environmentally sustainable way.


In addition to New York District staff, the regional team also includes experts from the Baltimore, Norfolk, New England and Philadelphia Districts. Customers have included USACE divisions and districts, the Panama Canal Commission, and the Kuwaiti Navy.

The New York District works with its parters in the region to utilize a wide variety of preferred and contingency management options for dredged material. These options include:

  • Contaminant Reduction programs that reduce exposure to contaminated sediments through source track-down, remediation, removal, containment, treatment, and/or capping of contaminated sediments
  • Historic Area Remediation Site (HARS) remediation practices that beneficially reuse dredged material at the HARS open ocean site
  • Habitat Creation/Enhancement/Restoration practices that use dredged material for restoring and creating wetlands, benthic habitat (including borrow pit restoration), fish and shellfish reefs, bird habitats and beach nourishment
  • Land Remediation practices that use treated dredged material to remediate landfills, brownfields, quarry sites and abandoned mines
  • Decontamination Technologies – The US Environmental Protection Agency, NJ Department of Transportation, and the U.S. Army Corps of Engineers have demonstrated several innovative treatment practices that use decontaminated dredged material to for construction grade cement, light weight aggregate, manufactured soil, and more
  • Confined Aquatic Disposal facilities that can be used as a contingency
