Sebastian Inlet

Client: Sebastian Inlet Tax District

Areas of Expertise: Inlet Management

The Sebastian Inlet is only one of our many successes. Find out more with CTC.

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:

  • 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.

Completion:  1987 – 1993

Consulting Fees: $435,000
