Congressional District: 18


St. Lucie Inlet is located in Martin County on the Atlantic coast of Florida, approximately midway down the state.  Section 201 of the Flood Control Act of 1965 authorized the project which includes a channel 16 feet deep and 300 feet wide, tapering to 10 feet deep and 150 feet wide through the inlet, and a channel 7 feet deep and 100 feet wide between the inlet and the Intracoastal Waterway. Project modifications were authorized in 1974 to include a sediment impoundment basin adjacent to the north jetty, extension of the north jetty (including 500 ft. weir section), a detached breakwater immediately south of the entrance channel, and construction of a new south jetty.

The St Lucie Inlet impoundment basin requires O&M dredging approximately every 3 years.  The last O&M event was conducted in 2018 and was performed with a mechanical dredge and approximately 512k cubic yards of material was dredged and placed in an offshore disposal area located offshore from Jupiter Island (Borrow Area B).  This material will be dredged from Borrow Area B and placed on downdrift beaches in the future. Funding was not received in 2021.    Funding received in FY2022 would be used to developed plans & specifications for an O&M event.  In the interim, Martin County has proceeded with O&M dredging on their own to ensure that the channel remains open.
