Dart plan involves crushing beach rock and returning it to beach as sand

Dart Realty said beach rocks could potentially be ground up into sand and returned to the site of its planned five-star hotel development.

“When we take out the sample of the beach rock, part of that process will show is what imprint the beach rock will leave on the seabed bottom. If we’re able to grind the beach rock up, we can put it back into that area on the beach rock as sand,” said Dart Realty COO Jackie Doak.

Beach rocks form naturally where salt water meets fresh water from the water table, and over the years, hardens into rock.

Part of Dart’s trial coastal works application is finding out if the rocks can be taken off site and crushed back into sand.

The DOE says the idea, on paper, could work.

“It remains to be seen whether this can actually work as beach sand, but technically, yeah, it does sound that it could be done, but I suspect there will be problems with it but that is indeed what the trial that’s being proposed is all about,” said Tim Austin, DOE Deputy Director

Mr. Austin said attempts have been made to transform older limestone rock into sand, but said that sand doesn’t resemble Seven Mile Beach’s native sand.
