A 7m wall has gone up on a Sydney beach: are we destroying public space to save private property? – The Guardian
“We really didn’t want to build a wall,” says Bob Orth.
But Orth is one of 10 residents of Collaroy, on Sydney’s northern beaches, who have each paid $300,000 to do just that.
And not just any wall. Construction began in December on a seven-metre-high sheer concrete structure below the residents’ properties, which overlook a beach that has become notorious for dramatic erosion every time there is a big storm.

Terminal groins are wall-like structures built perpendicular to the shore at inlets to contain sand in areas of high erosion, like that of beaches at inlets.
“Living Shoreline Techniques in the Marine District of New York, ” a document produced by the New York State Department of Environmental Conservation, lays out an approach to the coast that the U.S. Army Corps of Engineers should heed. It “emphasizes natural and nature-based solution to erosion control that will protect New Yorkers and the environment.”
