7b(2). CONSTRUCT A REVETMENT, PLACE IT ONSHORE TO THE EXTENT POSSIBLE
Although an offshore structure and created marsh is generally preferable, using this approach in deep water would require large amounts of fill to create wide intertidal zones. Large amounts of fill would need to be supported by large rock structures, leading to large environmental impacts. Therefore, in deep areas, a small revetment, placed onshore to the extent possible, generally has less environmental impact.
