On 3 September 1997, the US Army Corps of Engineers, Jacksonville District, and the Florida Inland Navigation District (FIND) executed a Memorandum of Agreement (MOA) to contribute funds for the Operation and Maintenance of both the Intracoastal Waterway (IWW) and the Atlantic Intracoastal Waterway (AIWW). Since that date, FIND has provided over $70,000,000 for the O&M of the IWW and AIWW. 

In 2022 O&M dredging was complete for the Palm Valley North Reach of the IWW. Additionally, a contract was awarded for construction of Dredge Material Management Area (DMMA) O-23 which will be completed in FY 23 and for O&M dredging of the Palm Valley South Reach which will be completed in FY 24. Funding in FY 23 will be used to complete plans & specifications for the Volusia Reach and Matanzas Reach of the IWW. If additional funding is received plans & specifications will be developed for the St. Lucie Reach of the IWW.
