On the release of his latest edit, R-Cal chats to Swellnet about love and other acrobatics. I am working on a gipa application to try and find out what community consultation they did for the second DA. Nothing can ever excuse extremely poor and ill-conceived designs. Should this critical lens be applied to other topics such as the Coolum wavepool? With the benefit of ignorance, having not seen the actual plans, I'd be surprised if the foundations were able to fail easily as I'd expect they'd have been designed explicitly to avoid it. Please include direct and indirect costs. I watched a 4 corners or foreign correspondent thing last year on the Japan sea walls. Would be interesting to know the depth as it goes out to sea as well as that gives options for offshore reefs to dissipate the wave energy, therefor preventing erosion. Highly unlikely! Men sand-bag properties on Collaroy Beach Arlington Building and a run of houses to the north circa 1922. I am not stock market savvy. The Northern Beaches took a massive hit by big surf and a king tide . Craig Brokensha on the Sunshine Coast there is a similar 'future' proposal for a rock wall between Alexandra Headlands and Maroochydore beaches. Bullshit. They've had a very very blessed life compared to anyone else in this country and that in return they would do such harm to a public place to save their private property is a bit sad. Yep, basically pork-barrelling on a massive scale and the Japanese sold them the lie too. Better still put them on a rocket for deep-space explorations [the missions that don't return] https://www.dexpan.com/pages/how-to-use-dexpan-break-concrete-rocks-easily. If they were 100% against it but felt they had no choice but to design/sign it, then they simply have no morals/ethics/backbone. At what point are they a write-off? Probably not council's fault then, happy to blame the owners! Mr Horton said current conditions have exposed a temporary rock bund that was put in place to protect the construction site, but it will be removed when works are complete. I suppose there are still those with more dollars than sense, but for me, the land is as good as built below the high-tide mark. The public should not suffer loss of amenity or pay the costs to protect it. Picture: Nearmap A subsequent image of Collaroy Beach from June 8, 2016. At this point, no-one can say if any consultation occurred, though the cynical view is council ticked the box by distributing flyers to the immediate neighbours, all of whom would want similar works built to protect their properties. Another week, another pumping day in the south-west of France. The council had an interest in preventing future erosion impacting Pittwater Rd, the main north-south artery on the NB. Surfers, sun bathers and swimmers. Construction of a seawall is underway to protect homes at Collaroy Beach. I'd imagine brendan and surfrider will have that covered. A "macabre" scene greeted surfers followinga mass kill of invertebrates. In the future, the problems may well be exacerbated by the above but they did not cause it "in the first place". Fight the good fight mate. Lance Knight. Yamashita (2020) "Living together with seawalls: Risks and reflexive modernization in Japan". Compare their prediction of how it would look with the reality shown above.. https://www.eventbrite.com.au/e/climate-change-and-coastal-erosion-the-g GOR coastal erosion webinar link for today at 3pm for those interested. Over the coming fortnight there's a couple more swell forecast from the east-northeast and that'll really put the structures to the test. Those days are gone, but we can make the future even better IF we use our brains like you say! Isolated, desk top engineering at its finest. Apparently this is just one part of the seawall. What some consider the ugliest wall in Australia could soon be bigger, with residents pushing to extend the Collaroy seawall on Sydney's northern beaches. 42 online submissions ALL supporting the wall but many seem to think it would be a sloping rock construction. The main issue is that the cables are protected in whatever is proposed. We took the easy way, down towards the ocean and along on the back of the dune. This is the only plausible outcome from the hard seawall construction and the engineers would have known this. It certainly doesn't make it the best decision though. nothings going to stop him on his daily dip. The finished work is 100 metres long by 13 metres high. Yeah nah. the whole sea level/erosion issue is here now ..hmm any idea's solutions you have come across? We all know there is significant increases in sea level rise..are we setting a precedent that if your coastal property succumbs to coastal erosion, you should be financially compensated? By creating offshore reefs that only interact with the largest [damaging] swell events, the normal beach processes can be maintained by allowing small to medium swells to pass unaffected and continue the normal flow of sand. Thats just a done deal. There are plenty of other spots along the coast vulnerable to rising seas and more intense storms but Collaroy is one of the most difficult to address. Beaches with hard structures can return, though it takes longer, and rocks and concrete in the wave zone also make for a dangerous combination. Its a wicked problem theyve got, in the true sense of the word.. For those who object to it, there is something hostile about Collaroy's multi-million-dollar sea wall. A shame too, as it would probably be a good strategy. EDIT: Just to be clear, the issue of erosion has nothing to do with sea level rise, climate change, or buying the latest board. It will improve beach access. In 2017, Gold Coast City Council funded, in conjunction with threatened property owners, an artificial reef offshore from Palm Beach. Yep. My experience with compulsory acquisition had to do with a Sydney motorway a few years back. Thanks Craig aod if you are THE Jody P, yes you are a ledge. They may have a wall, but there will be no beach in front of it. Same old issues, with a more educated market. It will still be a bargain now compared to 60 years from now if they do the same. Thats awesome. Links relating to the City of Sydney, and NSW in general - please read our rules before I find the whole thing fascinating, I had guys from the council to my face tell me of a future with 52 day heatwaves & in the same breath tell me of being concerened about extreme cyclones & erosion.

It's propped up by the NSW and local governments way beyond the importance or value of that stretch of private land. However, NSW has an intricate coastal management and development approval system and surely there's a paper trail for the various consents and approvals for this abomination which would be subject to FOI? For the most part I understand buybacks but, how will they appraise the value of these properties? Plenty others have discussed it. The project is part of the 1.3-km seawall proposed from South Narrabeen to Collaroy to protect both private and public assets in the suburb. The houses up the dune with no apparent erosion would be an apple compared to these lemons (for now). Pipeline specialist injured while duckdiving in heavy waves. Sea level rise equation is based on the Bruun Rule to ascertain erosion in open coastal areas like Collaroy. 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. Meanwhile, those on the other side of the divide are fearing the precedent of a return to hard structures and what this might mean for the rest of the Collaroy and Narrabeen beachfront, not to mention Wamberal, Old Bar, Byron Bay, and any other area where bad planning policy has created a wicked problem. I guess that the levees will give me a 100% guarantee that it'll never happen in my lifetime". Now a 7 metre-high, concrete, vertical seawall has been built in front of private properties on Collaroy/Narrabeen beach. The first application for a sloping structure was widely publicised and accepted by most who saw it. Look at offshore reefs around all the pacific islands. For me, the value of these properties is in the negatives and at the very least, its a big fat round calamari. "The community is not happy." Northern Beaches Council said there had been comprehensive community consultation about the council's coastal zone management plan for Collaroy Beach. Donohoe has presided over the Northern Beaches branch of the Surfrider Foundation for over twenty years, and hes currently livid with the council. The Feds and States are the only ones with sufficient means to do anything, but for them its a case of not my problem. Making it deeper? Confirming that they were involved in the initial design only. You can cry about why it wasn't their fault but that doesn't change anything at all. Inevitable as the ocean winning, is a painted "cock and balls" on that wall. Ignorant clown. There have been high profile storms on the NSW East Coast since the mid-70s. And in the approval documents was there a long-run cost benefit analysis evaluating the 2 treatment options of wall versus buy back and restoration. The exception of course is if youre a donor to the LNP then a $3M block of land can be sold for $30M!!! Locate courts, tribunals and offices. Not sure how they would fix them to the sand though. At what point do we put an end to this insanity. There's only a loss to be made for the purchases. Will be ironic if they have to pull it down for not meeting code on the steps. Collaroy Sea Wall With such close proximity to the ocean, our client tasked us with producing an alternative to the commonly used polystyrene forms. "We haven't had a flood here for 20 years you say. Will this mean sand depletion north and a build up south? Collaroy seawall project | Protection from coastal erosion Watch on Location: Collaroy NSW Our specialist staff were engaged by the Northern Beaches Council to construct the 250m rock revetment seawall in front of the Collaroy Beach carpark. Zen, it looks like an absolute disaster but Im guessing its not so much about coastal erosion but more about tsunami mitigation?? The root cause is building on the foredune. So says Brendan Donohoe of the conundrum facing Northern Beaches Council in relation to the Collaroy beachfront. Its also been the focus point for opposition to coastal development; an abject lesson about what results from bad policy. Here's also the appendices and figures etc: https://files.northernbeaches.nsw.gov.au/sites/default/files/collaroy-na Yeah, cheers I've been through them as well. The option of do nothing seems to have passed but it can always be thrown in as a baseline. I avoid it because I dont think anyone truly is except for a small % of big players who manipulate the market (or act like the house) and the rest just ride the peaks and troughs. A bit like asking journos writing about climate change to include references scientific papers talking about how CO2 is a greenhouse gas. In blustery, unfavourable conditions, people began lining up at 4.00pm Saturday afternoon (27 November) between Collaroy and Narrabeen to form a 'line in the sand' against the seawall's construction. Who could forget the MOLE building or the spoil from the North Head Sewage Works tipped over the cliff? Some relevant links from when I had a dig around before. If you look at the photo of the wall there appears to be a set of stairs built into the concrete for each property. There is a common denominator here, "Coastal" engineers with a lack of knowledge and understanding of coastal processes. bit of a worry but, when you buy a nice piece of land by the ocean in high risk erosion zone..why do tax payers have to buy the property back,,,surely the owner knew the risks ? Interesting to see if the slowed (design of) sand migration has had any knock-on effect for the likes of Tallebudgera- Burleigh and beyond. collaroy vs long reef, have always had signifcant erosion issues. The sheer number of cables there suggests to me that an offshore reef proposal would be unsuccesful. For example, during sunny conditions in Collaroy beach, constructive waves transport eroded sediments from cliffs and headlands to build up the beach. Cheers for the knowledge Craig. Great stuff. Im worried they will put one of these in at a beachie around here as the carpark and rd are imminent to be taken by the ocean and Im sure that will dramatically change the profile of that beach. These seawalls are easy to design, and easy to construct. The beginnings of a huge $25 million concrete wall in Collaroy on Sydney's Northern Beaches. With increased ocean levels comes all those properties around Botany Bay, Parramatta river, Georges river. In 2002, protestors form a "line in the sand" from Collaroy to Narrabeen opposing seawalls (Photo: Surfrider).

It's like companies using buybacks in a crisis. Its all about the squeaky wheel. This has cut into the base of the dunes below the surf club. Environmental vandalism or gross negligence? The council will buy me out at any price if things get too hot". Bumper Farrell had the prime position. Dates announced for Spencer Frost and Guy Williment's film shot in Russia's far east. the above-average wave heights and elevated water levels are to blame. Also I'm suspecting at the lga level the up front investment to do this work can be a hard sell. If a construction like that ends up being the only realistic option then so be it, but at least they need to be transparent about how they got to that point, and ideally accountable in future if it goes south. I saw the construction going in, says Donohoe of seeing the area cordoned off earlier this year, and thought they were building rock revetments. increases social amenity". 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. development, carparks & roads behind the hind dunes leading to biketracks, walkways, supporting the community including @Tango Hows the Seawall holding up? Staged retreats seem the best option, but also some councils are genuinely desperate to embrace the most apocalyptic climate change forecasts. Unlike other approaches like soft beach nourishment, they offer a long term solution to shoreline erosion. From the last set of minutes from the Wamberal Seawall advisory Taskforce Nov 18 2021. This just a year ago was a nice Sandune. A weather-beaten cement plaque with the year 1952 is still visible along a section of the seawall. The also don't grow in sand so they won't be of any use to prevent coastal erosion on our open-ocean beaches. First and foremost they say It's for erosion control but as you've seen after 2011 they did pretty much sfa. They have just invested in an asset that requires 60 years of maintenance. I dare say the neighbours are on notice too. We all have valuable opinions, but they need to be separated from facts at all times, especially when it comes to Journalism. You can go to court to complain about the price, but you cant object to the acquisition. As a result, if the sea erodes the shoreline (and the tidal level moves inland) it encroaches upon land once part of someone's private land title. Stupid dumbfucks. The only way now is to harness the power of coastal construction science and engineering. The politicians and land owners actions are an entirely separate discussion and I'm not entering into that minefield! Take a chill-pill mate, or possibly the whole packet as it appears you need them. >> and the ocean will wash it all away again in the next big swell. However, Craig, when you say "Comparing the swell to those of last year it wasn't of any major significance but it shows the futile efforts trying to protect property with a hard structure." The process is cyclical, however short-sighted development upon the foredune, built during times of a wide beach profile, impedes the system. My NSW water buddy says MHL are coyboys. Please enable it to continue. >>Is that because he has been paid already?? What insanity! It is a difficult and wicked problem. Old dude making a dash for it, budgie smugglers and a cricket cap. Five years ago, residents along Collaroy Beach watched helplessly as enormous waves smashed into their backyards, collapsing pools and patios of their multimillion-dollar waterfront properties. (AO) Just ugly, clog up the waterways etc. For a couple of furlongs it was quite close to the ocean but nobody cared. The theory is that the waves break further offshore, soaking up wave energy that would otherwise erode the leeshore dune system during storms. There isnt much fetch so its only ever weak 1-4ft tops of onshore wave after wave onslaught, this a particular problem at high tide caus most bays and points usually go flat at high tide but under an easterly scenario the easterly windswell pushes right up to the dunes, and easterly swells require lots of wind and from what Ive read on swellnet these large storms if the pressure is low enough will raise sea levels higher than normal. Hi Craig, the short answer is I'm not sure as I have been out of NSW too long. We have summarised some key facts about the first of the Collaroy owners' seawalls. Surely, private properties can be protected but public amenities will require huge ongoing costs to keep up with the public requirement (sand nourishment is the first thing that comes to mind). I have written to the Office Of Local Government about my concerns over the hiding of the second DA. There's been a lot of work done to gain a better understanding of the value of the beach re both market and non-market economic benefits. 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? High-quality Collaroy Wall Art designed and sold by artists. For some it. There's been a lot written about the challenges of the various adaptation options, including the purchase of private lands. Surge and erosion even on protected beaches on the Mid North Coast today is nuts. I am pretty sure the link was correct when I posted it. Imagine the carnage during the next ECL. Comparing the swell to those of last year it wasn't of any major significance but it shows the futile efforts trying to protect property with a hard structure. Both Brendan Donohoe and Angus Gordon, and other people Swellnet spoke to, admit to being blindsided by the construction. All of which. Like Stockton, the Collaroy seawall has resulted in the loss of the beach immediately in front of the wall caused by the dissipation of wave energy. The road is the public asset to be protected yes linked to their actions - but if it was really only just about PW road then surely a more cost effective way would have been to introduce less expensive and arguably more effective measures as I understand earlier reports have indicated including reveg and rock? The market knows the insurance companies know this. I just can't see HOW these monstrosities ever get approved, purely on an engineering level. This will give all all a better insight into what's going on with these projects. 47 votes, 47 comments. Yes, blowie, I've yet to see anyone our age advocating for a soft solution. I don't disagree with most of that. I put up links to both DAs the other day.
