Breakwater Construction at Petty Harbour SCH, NL

The proposed project at Petty Harbour SCH includes the construction of a new breakwater. The proposed location for the breakwater is east of the SCH marina and accessed via the southern shore of Petty Harbour. The proposed breakwater will extend north across the waters of Petty Harbour, but the head of the breakwater will pivot to the west. The breakwater will be composed of a core substrate, covered in filter stone, then covered again in approximately two layers of armourstone of differing sizes. The seaward side will be more robust to accommodate wave action and storm surges.  From the shoreline to the proposed farthest submerged point of the new breakwater, the length is approximately 120 metres. The anticipated footprint of the new breakwater is approximately 8000 square metres.
