Sebastian Inlet was initially constructed to relieve flooding in the Indian River Lagoon, and was eventually stabilized by jetties – leading to erosion of downdrift beaches in Indian River County. In 1988, the District adopted the first Inlet Management Plan in Florida – a long term management plan for the maintenance of the inlet and adjacent beaches.
Coastal Tech – GEC:
- developed and initiated implementation the long term management plan for the maintenance of the inlet and adjacent beaches;
- obtained bathymetric surveys ;
- assessed coastal processes at the inlet based on existing reports, historical aerial photographs, bathymetric surveys, and field investigations;
- applied numerical models to evaluate the erosion and sedimentation at the inlet;
- performed an economic analysis of alternative bypassing systems.
- obtained a twenty-five year FDEP permit (the first 25-year permit ever issued by the State) for the continued maintenance of the Inlet; and
- designed, prepared specifications and contract documents, and provided construction phase services for maintenance dredging and feeder beach construction at the Inlet.
