The New York District is responsible for maintaining the Federal navigation channels within the Port of New York and New Jersey. Maintenance of these channels via periodic dredging to authorized dimensions is critical to safeguarding commercial and recreational navigation within the port. NYD is committed to environmentally and economically sound management of maintenance dredging material as defined by applicable laws, regulations, and policies.
A Dredged Material Management Plan (DMMP) is a long-term strategic plan for the placement of material to be dredged from Federal, State and local [new and existing] channels. A DMMP ensures that there is adequate placement capacity to properly manage dredged material in an environmentally and economically acceptable manner. The DMMP Implementation Report (IR) for the Port of New York and New Jersey was published in 1999. Several updates have since been made to this DMMP, with the most recent update issued in 2008. In 2022, the NYD was allocated funding to develop a subsequent Interim DMMP Update.
