A Memorandum of Agreement with the Florida Inland Navigation District (FIND) to contribute funds for the Operation and Maintenance (O&M) of both the Intracoastal Waterway (IWW) and Atlantic Intracoastal Waterway (AIWW) was executed on 3 September 1997. Since that date, FIND has provided over $70,000,000 for the O&M of the IWW and AIWW.

The last dredging event for the AIWW occurred within the Sawpit Reach. A construction contract for O&M dredging was awarded in September 2018 for approximately 600K cubic yards of material to be removed out of the Federal channel. 95% of this material was beach quality and was placed on the beach at Amelia Island State Park. The remainder of the material was dredged and placed in the already constructed dredge material management area DU-2.  The next O&M dredging event is anticipated for 2022/2023.  Funds received in 2021 will be used for channel conditions surveys and updating National Environmental Policy Act (NEPA) documentation.
