Coastal and Wave Overtopping
Following the tidal flooding experienced at the beginning of 2014, the Department of Infrastructure engaged a specialist engineering consultancy to develop concept options for flood and storm protection. The work focused on the Department's assets at known problem areas, mainly around the Island's ports.
The main findings of the review are captured in the Executive Summary, which is attached below. The full report is also available.
The options identified would involve significant capital investment by Government and in some cases would have a visual impact on the locations concerned. The Department is planning to undertake a period of community engagement before deciding what steps to take next.
