Sebastian Inlet District: Responsibilities and Stewardship

Central to its mission of maintaining the navigational channel connecting the Indian River Lagoon and the Atlantic Ocean, the Sebastian Inlet District is responsible for transferring sand that migrates into the inlet system to downdrift beaches, consistent with the Florida Beach and Shore Preservation Act. To fulfill this responsibility, the District conducts periodic dredging, channel maintenance, and beach renourishment projects approximately every four to five years.

Using a science-based approach, the District continuously monitors sand accumulation in the inlet's 42-acre sand trap and navigational channel. This work is supported by a research partnership with Florida Tech and semiannual bathymetric surveys of the inlet system and surrounding backwaters.

To support safe navigation, the District has installed and maintains navigational channel markers connecting the Intracoastal Waterway (ICW) to Sebastian Inlet. The District also maintains critical inlet infrastructure, including the North and South jetties and adjacent shorelines.

The District operates a six-acre Dredged Material Management Area (DMMA), located northwest of the tide pool, which serves as a sand storage site for emergency beach fill and dune repairs.

Environmental stewardship is another important component of the District's work. In collaboration with marine scientists, the District conducts both permit-required and supplemental biological monitoring of important habitats surrounding the inlet. These include seagrass beds on the western flood shoal, nearshore hardbottom reefs south of Sebastian Inlet, and beaches within the Archie Carr National Wildlife Refuge. These habitats support a diverse range of marine and coastal species.

The District works closely with Sebastian Inlet State Park, the Florida Department of Environmental Protection (FDEP), and other local, state, and federal agencies. Since 2008, the District has secured $12.5 million in cost-share grant funding through FDEP's beach funding assistance program to support its projects.
