The structure is Grade II* listed and reaches a total length of 2.4km, for which there is no parallel in Wales (GAT, 2017). The Breakwater is formed by a wide rubble mound with a crest around the waterline, with a vertical blockwork-walled superstructure on top (Figure 1.2). Holyhead Port is a strategically important international ferry port, providing the main link between Ireland and mainland UK. The Breakwater forms part of the essential infrastructure for the operation of the Port, providing shelter from a more extreme wave climate to the berthing ferries and other vessels. Without the Breakwater it is likely that the wave conditions would increase to the point that the operation of the ferries is no longer viable, resulting in the closure of the Port and the loss of the international link to Ireland for Wales and England. The Breakwater protects and shelters approximately 260 hectares comprising the Outer Harbour, Port of Holyhead, and to a lesser extent the Inner Harbour against port disruption, flooding and coastal erosion. The Breakwater allows the marina, sailing club, coastguard station, Royal National Lifeboat Institution (RNLI) lifeboat station, maritime museum and Port to thrive, supporting a significant number of jobs. The Breakwater supports the economy of Holyhead and the wider Anglesey and North Wales economies through its role in protecting the Port and the Outer Harbour, supporting opportunities for regeneration and development, and preventing flooding from wave overtopping. Since its construction, the Breakwater has been subject to considerable wave action which has led to the movement of the rock blocks that make up the rubble mound and erosion of the rubble mound itself (Plate 1.1). As a result, the rubble mound has been subject to regular, expensive, maintenance through the partial replacement of lost material. The vertical blockwork wall structure is also subject to periodic damage which is repaired on an ongoing basis. 30/07/2019 EIA SCREENING REPORT PB9014-RHD-ZZ-XX-RP-Z-0062 1 390000 392000 Breakwater Lighthouse © Haskoning UK Ltd.
