Collaroy resident Tony Cagorski lost more than 10 metres of his yard during the weekend's wild weather, undermining the foundations of his home. Construction costs are 80% homeowner funded. The erosion at Collaroy/Narrabeen Beach is not particularly significant, unusual or surprising. And there's no risk. Please please please don't let those greedy fucks do this to Australia. Aside from high tides and Tsunamis, Im guessing most islands/atolls dont suffer much erosion when surrounded by reefs? Unlike politicians, scientists are usually very open with sharing their knowledge and data, to help inform the public. The local community group has been protesting against a seawall for almost 30 years. The Gold Coast has undoubtedly the most at risk coastline in Australia. the Senior Environmental Officer" Northern Beaches NSW govt!! >>Is that because he has been paid already?? Can somebody please sack almost ALL so called coastal engineers for Fuck's sake! Super difficult problem, maybe councils could buy beachfronts then lease back the properties. There are many software suits now that can handle very complex near-shore modeling, including sediment transport from wave and current action. I'd imagine brendan and surfrider will have that covered. They have just set a precedent for the whole east coast of poor me multi millionaire landowners to set up squeaky wheel collectives. This is an example of the walls theyve been placing. Adjacent a second wall constructed just to the north, the half finished revetment was torn to rubble with dangerous rebar, boulders and cement being washed into the surf zone. Yep need to see front on pic The beach is now too dangerous to walk along and it's one big eyesore. A shame too, as it would probably be a good strategy. . The only way now is to harness the power of coastal construction science and engineering. Operates out of the same premises. The coastline in SW Vic has evolved to respond to a dominant SW swell and storm pattern - that's why the beaches face the way they do. However, while they prevent further shoreline erosion, they do not deal with the causes of erosion (French, 2001). My 2c on the buy back scheme - NB Council won't have 50+ million sitting around to buy them all back at once (and NSW Gov wouldn't be in a hurry to give them the rest) so they'd have to do it say a couple per year, but at the same time, that leaves the others who can't be bought back vulnerable and at risk of further destruction if another mega storm decides to show up, which in the current climate you'd have to think is pretty likely. Yet for some reason the Collaroy/Narra stretch seems to get flogged not only by mother nature but by poor coastal management approaches time and again. there is no excuse for purchasing a property on the beach in the last 30 years let alone 5 without an inkling of understanding of the risks. Offshore reefs would be expensive , but we are already spending 100's of millions on bad solutions that actually cause more problems than they solve so money cannot be used as an excuse. Might discuss that with @surfriderfoundation and Surfrider Foundation Sunshine Coast, and those people and localised groups finding themselves in positions of having to fight this idiocy. Men sand-bag properties on Collaroy Beach Arlington Building and a run of houses to the north circa 1922. info a new build now paid by the public purse. It has to be worth a look. Shows what not to do, i mean it'd have some value in an inlet or lake subject to openings to the ocean in storm surge/high tides. processes currently-exported iron ore, bauxite, and alumina into green. EDIT: Just to be clear, the issue of erosion has nothing to do with sea level rise, climate change, or buying the latest board. Environmental vandalism or gross negligence? I saw the construction going in, says Donohoe of seeing the area cordoned off earlier this year, and thought they were building rock revetments. The group aims to raise awareness of the impact that the building sector can have while pointing out that more drastic measures need to be taken, as most countries do not include full building. After five years and four contests, the performance level at Kelly's Hot Tub hasn't evolved but instead gone the other way. oh yeah and someone call security. Now digging up the facts of this case would prove fascinatingthe applicant, the judges, the arguments, the ruling etc one if there is precedent for seeking compensation for judicial rulings made in error. With increased ocean levels comes all those properties around Botany Bay, Parramatta river, Georges river. I am thinking that sad as it may be, we will never be able to turn back the clock and have a natural passive coastline of Sandhills and trees. "I really like living here deep in the bush, close to nature. Criticism of the debris left on the beach, the erosion as the sea ran up against the wall and drew away all the sand during January 2022 swells and the manner in which these works have been carried out prompted council staff to investigate a number of times during the heavy swells, and has been under regular inspection since then. Is Carties a perfect candidate for a coastal engineering and resculpting project that kills two birds with one stone: that fixes the harbour entrance shoaling problem and turns Carties into an actual quality wave? I first noticed them when I went to Nijjima island in the early 90's and asked what were they reply was to protect the land from erosion.they actually had the moulds for the TP's there and just kept making them when needed.. https://www.sydneycoastalcouncils.com.au/sites/default/files/JRCorkill_A(2)_Prop_L_Rev_67-84.pdf, yes, Blindboy, I am guessing they had absolutely no input on the final [or initial] design what-so-ever as they were only used as a consulting service by the Coastal engineers. This issue is not exclusive to the NB or sea level rise or storm surge. Their ultimate solution was a combination of 3 things- a rock boulder seawall buried in the dunes as a final line of defense in extreme erosion events to protect private properties behind (this seawall actually runs for the full extent of the Gold Coast nth beaches but is rarely seen as it is completely buried under dunes/vege), an offshore reef, also rock boulders, to attenuate wave energy under normal conditions thus widening the beach in its lee, and lastly- sand nourishment, adding more sand to the beach system. Looks perfect for high tide backwash to spread up and down the beach. And this is on a small, weak windswell from the south-east. I don't disagree with most of that. The question is why did the owners go for such an unattractive solution that by all appearances seems to have blocked their beach access. An "Engineer/s" designed this monstrosity and other "Engineers" approved it. Edit: The estuary was in an area protected from the ocean and the cliffs only faced small wind chop and the tides. It's going to be interesting to see how it holds up after this weekend/early next week with another round of resonably solid E/NE cyclone swell hitswho's going down to take more photos and show the aftermath?!! "Environmental vandalism or gross negligence?". "Have you ever seen such a magnificent view as the one from our balcony overlooking this active volcano? I think this was done for the first DA, the sloping rock wall, rather than the vertical one that was actually built. Also, ALL the Numerical modeling was done in comparison to the current altered beach-state and NOT to a natural beach-state so there is bias in modeling things that way even though the beach state is not natural any more. The co-founder of Ksubiis to launch a '70s surf-inspired hotel on New South Wales' Mid North Coast. the hardest decisions should be the easiest. Protesters linking arms on the beach in 2002. @dawnperiscope. A seven-metre high wall erected to protect beachside mansions from being washed away has sparked debate among locals in a wealthy Sydney suburb. Seawall construction isnt mentioned. It's a travesty in so many ways and a very poor precedent for other parts of the coast which will be deemed vulnerable to sea level rise. San Sebastian surfers are fighting a wavepool in their hometown, which is also the hometown of Wavegarden's founder. Tonights high tide is 1.34m, tomorrow morning is 1.96m. The council will be the lone 'interest'. You can cry about why it wasn't their fault but that doesn't change anything at all. I mean, did someone forget about the old idiom about 'shifting sands' or what? Big walls like this one are getting smashed and although for the most part they are still there, everything behind them is going. Man, that'd get old real quick, happy to pass. You shouldve known by 1990. A number of properties along the oceanfront from Narrabeen to Collaroy were seriously endangered by erosion during a large storm swell in 2016. Establishment and set out of site survey control points. Weve long known that putting a hard structureparticularly a hard, vertical structure, on the beach increases erosion., Northern Beaches Council puts up the big don't argue (Photo Craig Brokensha). Other than buy the land and let nature take its course Im really interested to know if there are any other options - not brutal like this but that might be effective ? Thanks heaps for the update Craig. Will it make Carties better or will kooks just ride into the wall even more. It is possible that this is part of the Silverback's Seachange pork barrel rollout. A few pics. Ben, yes there are submarine cables and the protection zone is there to prevent damage to the cables, but I don't think that would preclude construction of reefs, it just means that any proposed reef design/construction would have to be in consultation with the cable authorities. Dates announced for Spencer Frost and Guy Williment's film shot in Russia's far east. It might take a bit of digging to prove it, but the evidence is accumulating already. Plenty others have discussed it. To my way of thinking, and with a working understanding of government process, the real issue is the approval process. These very costly bandaids never work and continue to fail while extending the problem to adjacent properties that don't have the wall. The Collaroy Beach seawall project was put to the test for the first time today with the arrival of a moderate to large east-northeast groundswell from ex-Tropical Cyclone Seth, coinciding with a king tide. Re: "I don't think that would preclude construction of reefs". I have written to the Office Of Local Government about my concerns over the hiding of the second DA. Fvck the coastline. The DA for the Collaroy seawall was approved while the Northern Beaches Council was under administration. There's only a loss to be made for the purchases. Amongst other things, it is illegal to "establish, maintain or use a spoil ground or other ocean disposal point (including dumping materials at sea)".
