Isn't an extension to the Point Cartwright breakwall on the cards aa well? And the properties either side?? If the council are desperate to get a liability off their books then they have totally screwed it. The thing is- in those pics, behind the walls, there's really not much to protect. Surf Breaks Inc. Coming to a beach near you ! Perhaps at best, the council acquires the land and owners get a sum to relocate to a 'normal' house west of Pittwater Road (god forbid). They are a method of hard engineering. 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. 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. [ask GaryG] Collaroy Sea Wall With such close proximity to the ocean, our client tasked us with producing an alternative to the commonly used polystyrene forms. Will it make Carties better or will kooks just ride into the wall even more. as the article states coastal erosion has been known since the 20s in that area and has been studied meticulously ever since. More than a year after severe storms damaged property in Collaroy, construction of a long-awaited sea wall is underway. Including the residents behind the great wall. Operates out of the same premises. On Saturday November 27th hundreds of locals came down to Collaroy Beach / North Narrabeen Beach in grim weather conditions to protest the monstrous 7 meter . Turned this place into a concreters paradise. The people responsible for awarding the contracts get huge kickbacks. 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. I am not stock market savvy. Not sure why coastal ginger beers (engineeers) assigned by local councils just keep getting it wrong, but it would be fascinating to go through the meetings minutes of how these get passed, and the deceptive and misguided arguments that must be being put forward. 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." At what point do we put an end to this insanity. First it was a track. (9News) But the structure has divided locals, with many describing it as an eyesore, and there are concerns it may wipe out the beach entirely. Whether concrete castles or sand castles, buildings that close to a sand shoreline must be living on borrowed time. South Narrabeen beach is now useless to anyone. Nature fights back. And ALL received in a 3 day period 17-19 July 2017. If you look further to the north you can see an old, crumbling seawall (due for replacement- fucking industry perpetuates itself) and you can see the water breaks right on it, there's no sand. Lance any surf info about Middleton Reef ? Whether the NSW state government / local council want to backflip with a pike on their current failing seawall master plan is another thing. A shame too, as it would probably be a good strategy. 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. Soon It Will Be Filled With Concrete.'. The public should not suffer loss of amenity or pay the costs to protect it. The owners of those properties must have the most amazing collection of dirt on the political class. The legacy of that approach will be something future generations will have to live with.. LGA's apply for state and federal funding on offer for range of purposes. 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. Photograph: Wendy Harmer Coastal municipalities have been tackling the problem with a suite of measures. Her Majesty Queen Elizabeth II died in Balmoral on 8 September 2022 (GMT) at age 96. The only feasible way forward without wasting any more council and tax payers money to protect the properties in question is to acquire the properties at any cost and return them to a naturalised stated. Building a vertical [with over-top] wall is about as insane a design as you can get, as stated and proven by all the intelligent people on this forum. Perhaps the omission was because in 2002, protestors, led by Brendan Donohoe and Surfrider Foundation founder Tom Kirsop, formed a line in the sand stretching from Collaroy to Narrabeen opposing the construction of any seawalls. nothing that a annual maintenance fee paid for by the taxpayer can't fix. Is there a sea wall at Collaroy? good pics there willi, hadn't realised this. It will still be a bargain now compared to 60 years from now if they do the same. The software built for Kelly's wave pool was also a big leap forward to modeling actual breaking waves and I really hope they share that knowledge with the rest of the scientific community to help forward our understanding. Bite the bullet and start buying the properties back and bulldozing them. Great article highlighting the competing interests of the natural environment and local councils (which are too easily manipulated by wealthy stakeholders). Hopefully there's someone with deep pockets able to go after the truth of the matter. If you don't know know shit about the processes of the ocean and coastal erosion then please put your hand up and say so. Agree 100%. Willi, how would easterlies impact the Great Ocean Road coast? Isolated, desk top engineering at its finest. OMG!!! Maybe start a thread in the Forumsand you must have a few Wild sea tales to tell with 560 Lord Howe trips under your belt. Re: "I don't think that would preclude construction of reefs". I doubt there will be a demand for the effected given the inevitable. I will try and find some pics of my area. Protesters linking arms on the beach in 2002. The reef/sand nourishment are both mainly designed to widen and protect the public property, ie the beach, in front of the buried seawall. Beaches with hard structures can return, though it takes longer, and rocks and concrete in the wave zone also make for a dangerous combination. The council will be the lone 'interest'. @dawnperiscope. A few years on when I visited I suggested a stroll along the cliffs at the estuary and they replied that its to dangerous now as theres been heaps of erosion for some reason. More to come once the other residents agree to pay their contribution. I think this was done for the first DA, the sloping rock wall, rather than the vertical one that was actually built. Just wondering if the stairs built into the wall are private property? Men sand-bag properties on Collaroy Beach Arlington Building and a run of houses to the north circa 1922. Ray Collins eat your heart out.. Good find. I looked into this again yesterday. They have access to and use a large suit of software modeling tools, but unfortinately a lot of them don't have outputs that non-scientists can get their head around [just numbers which are meaningless on the surface unless you understand what they represent.] Yep. Anyone who has been to Chiba in Kanto will have seen the Tetrapod formed surf breaks there. Rad demo john interesting as Craig said to see the changes in shock waves returning seaward. Wow, that is ugly even by brutalist/modernist standards. The question is why did the owners go for such an unattractive solution that by all appearances seems to have blocked their beach access. Here's a screengrab from the website about the proposed breakwall extension: It seems that the main concern about the extension is the interruption of the natural flow of sand onto Mooloolaba beach and hence increased erosion risk. Here is the DA for the wall. To add a bit of controversy, I've often wondered: Is Carties borderline just a novelty wave? What they could all agree upon is that council has lost the trust of all whove opposed the seawall over the decades. Given Council has already completed protection works on public land, and there's been a lot of talk about the owners' seawall, understanding all the facts is important. Though still in its early days, the reef - which cost $18 million - has maintained beach width since it was completed in 2019. I looked at the Bruun rule - i think it was roughly 10cm sea level rise = 1metre of beach vanishes? No-one wants to see visible structures built along the beachfront. So whats your thoughts about using tax payers $'s to buy back endangered properties from natural erosion and as I asked Zen.are there any solutions other than just moving people property back from the Coast? Could be some good entertainment next time some serious swell hits. In a story on Northern Beaches Review, Bob Orth, who lives in one of the houses behind the seawall, said the seawall should inspire others to do likewise. Again this can only be taken as opinion without proper scientific references. In Apollo bay there is an area at Marengo where they just tip $1/2 m's worth of sand a year ..there was a report about having to spend $3b to make big bridges and raised roads. Ratepayer/taxpayer bailout, so business as usual whatever happened to caveat emptor? It is a difficult and wicked problem. The concern about the seawall stems from the dynamic nature of sand dunes and how introducing a hard structure onto the foredune interferes with the natural state of flux. Looks perfect for high tide backwash to spread up and down the beach. 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. They must only exist on a dense (and expensive) schedule of maintenance, no doubt. Between these three, you can protect any shore from water erosion. You'd think that would then open it up for more legal action (aka why did ABC get first dibs and XYZ missed out?). As good as a house on the beach would be imagine how much more beautiful the East Coast would be with a 1km + building buffer from the coast depending on the terrain. Look at offshore reefs around all the pacific islands. https://www.smh.com.au/property/news/coastal-properties-at-highest-clima https://www.abc.net.au/news/2022-01-17/will-climate-change-put-an-end-to Kala Grace In Dramatic Rescue While Competing In Backdoor Shootout, 'Corners Of The Earth: Kamchatka' Tour Dates, Watch: Hossegor Super Session January 6th, Australian Designer To Launch Crescent Head Hotel Amid Local Development Concerns, Dead Marine Life Washes Onto South Oz Beaches After Flooding, Watch: Ryan Callinan // Beneath A Pear Tree, Watch: Cronulla's Jarvis Earle Wins World Junior Title. In this case there is evidence that the council and land owners subverted the approval process. For some it. Yep, basically pork-barrelling on a massive scale and the Japanese sold them the lie too. The erosion at Collaroy/Narrabeen Beach is not particularly significant, unusual or surprising. Good point, Lilas, but I think the issues around hard structures and beach environments have been established for so long and are so well known in the coastal management field that it's taken as read. There have been high profile storms on the NSW East Coast since the mid-70s. By doing so they have encouraged similar management intervention from beachside landholders by 1. demonstrating part liability for coastal erosion processes by building such a structure that threaten adjacent properties and 2. I have a blanket policy of not feeling sorry for people owning properties worth multiple millions of dollars, who have lived the better part of their lives walking from their beachfront home directly onto the sand. No fuckers complained about the rebar reef. Usually done by compulsory acquisition with the government working off existing market prices. This is where I live. I assume this would all depend on the power of the state government/council etc to cap buyback prices, similar to land buybacks for roads, airports etc. All the reaserch I did seemed to show that the headland affect and beaches just north of those headlands, i.e. On the release of his latest edit, R-Cal chats to Swellnet about love and other acrobatics. Lindsay Fox is happy as a vegemite as he now has what he wanted all along, more real estate to land his helicopter on. After five years and four contests, the performance level at Kelly's Hot Tub hasn't evolved but instead gone the other way. Proven time and time and time again that sea walls do not work- period. But unlike a rock revetment at Stockton, which gradually collapses into the beach, Collaroy's sheer concrete wall relies on deep foundations to stabilise it. It never went to a vote of councillors, where it would have been likely voted down . There's been a lot written about the challenges of the various adaptation options, including the purchase of private lands. He said when the work is complete, sand will be pushed up to cover most of the seawall. 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. Looks like the council are aware of the liability concerning the still submerged rocks. That's assuming the properties are still worth something to the market. What sort of idiots approved this shit? Thats awesome. Existing market value must take into account that houses have erosion problems. Precarious! Not much wriggle room for negotiation, and in a volatile market owners are more liable to be offered (and it's an offer they can't refuse) recompense that sits at the lower end of the scale. Hourly Multiple Swells Wind Highlighting Model Units ft, mph. You don't have to look around the world because the Gold Coast has implemented the only effective "non- ugly as fuck" option at Palm Beach Qld. Thats just a done deal. the council up here is anti sea walls, but there is a thread that runs through them very much of "stuff the beachfront guys - they are rich". Surely a planned retreat is the only way forward. As the article states, in terms of erosion, vertical walls don't work and actually exacerbate the problem. Go figure! That's the only thing stopping all the sand at the base of the wall getting washed away. If you're looking to protect your property from flooding with erosion control in McHenry, IL and the larger Chicagoland area, give Seawalls Unlimited a call at (815) 331-8830. There are many software suits now that can handle very complex near-shore modeling, including sediment transport from wave and current action. Our timber guide wall formwork is not only reusable and 100% recyclable, it also prevents dangerous polystyrene fragments from entering the ecosystem. I'd be happy to help draft it offline. Its all about the squeaky wheel. That is why this option was selected for Palm Beach Qld, and I think should be considered for all the other coastal erosion hotspots along the NSW coast as well. Councils of times gone by should never have approved houses to be built on the beach in known spots of erosion aswell as houses on the beach full stop as sand dunes have there purpose . The devil is in the detail and the more we understand the science behind it the better. I've written about it before but the real reason here is money- it is massive pork-barreling on an unprecedented scale. Should have taken the high road. Yea I agree with this. Collaroy Seawall Detailed Survey for construction of a new seawall in highly sensitive erosion zone. If it were replicated along vulnerable areas of the NSW coast (and that of other states) we would never be able to afford adaptation. Furthermore they have facilitated an increase of erosion to adjacent beaches. High rise apartment buildings demolished when they realised it was the most cost effective and environmentally sound long term solution. Construction costs are 80% homeowner funded. Ha! Imagine how fun that'd be with your mates on a boog. Then there is the question of the parameters given to the designers of the second structure. Lawsuit waiting to happen when a swimmer/surfer gets nailed by a rogue piece of concrete either down the 'Roy or up towards Northy. Zen, it looks like an absolute disaster but Im guessing its not so much about coastal erosion but more about tsunami mitigation?? 314k members in the sydney community. The Act was introduced by Rob Stokes, the NSW Minister for Planning and member for Pittwater. EDIT: Just to be clear, the issue of erosion has nothing to do with sea level rise, climate change, or buying the latest board. Certain death. Last Model Run: 15 Jan 11:00AM Local time (AEDT) 15 Jan 12:00AM GMT Data Status: OK. Run Age 9hrs. Scientists need to be able to communicate the results of simulations/tests in a way everyone gets, not just a bunch of numbers. I've got a mate who works for MHL as a coastal engineer. 47 votes, 47 comments. There's no sense at all in building something like this from an engineering perspective. Make his name famous: Peter Horton. I like the cut of your pedantic job, there Lilas. Honestly he might be correct based on the Manly erosion hahhaa. Also any factual statements need reference links to scientific papers backing them up if they are to be taken seriously The matter is currently under investigation by Environmental . gsco, I'd have thought that the first hurdle for any enhancement - besides the environmental impacts - would be the issue of access and whether the investment creates something with the most benefit for the most people. More often than not, the pollies retiire and are parachuted onto the boards of these companies and live out their lives having enriched themselves quite nicely. 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. Yep need to see front on pic Though they were quick to remove signs only recently erected on the beach.. https://www.smh.com.au/national/nsw/council-was-asked-about-danger-signs To be replaced with signs "Collaroy artificial reef project 2023", This is a glimpse of what a beach could be; following sensible Council planning; (post storms in 1974) eg. (btw if you're the Jody P I'm thinking of, you're an absolute legend mate!). Pretty incredible and frightening stuff. And find outwhy you'll soon hear a hell of a lot more about them. The recently constructed Collaroy seawall yesterday failed - or passed - its first real test, depending on which side of it you stand. consultant reports and community consultation no doubt funded by state money. other than just the width of beaches increasing, has anyone actually seen a full dune rebuilt. Lets bring it on. Some family recently went through this as their house sat above the construction zone for the Spit / Northern Beaches Link tunnel. Please enable it to continue. Maybe you New South Weleshpeople do things differently. >>Is that because he has been paid already?? Where the only issue is private property things are a bit simpler. Spot on tango. Links relating to the City of Sydney, and NSW in general - please read our rules before Aside from high tides and Tsunamis, Im guessing most islands/atolls dont suffer much erosion when surrounded by reefs? (This statement also doesn't specify what type of HARD structure. Would suck if you got amalgamated into Northern Beaches council then had to pay tax for this. However, a few queries regarding your post: "Sure if youve bought the last 5 years ignorance cant be an excuse" - why does five years give one grace? These contracts to the construction companies are worth hundreds of millions of dollars. Vertical Seawalls Vertical seawalls are exactly what you think. This would be a better solution, I think. The council now will not release the relevant documents without a formal application and even then would no doubt find reasons to withhold the significant parts. They are multi millionaire asset owners. Jeez. Seawall construction isn't mentioned. 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. Also, it's a not so secret secret, anyone who speaks out about this have been known to disappear. But obviously no owners want to give up tax free capital gains.. dunno has to be a solution that doesnt destroy the beach like collaroy or completely crush home owners, they arent all pricks. Can't see sand staying around with all that crazy activity. Normally large swells from the SW have very little affect on the beaches around here because the great ocean rd is comprised of Rocky headland after headland. High-quality Collaroy Wall Art designed and sold by artists. Hey BD. Also, "some councils are genuinely desperate to embrace the most apocalyptic climate change forecasts" - in your view what are "apocalyptic forecasts" of climate change and which councils are you referring to? Well now we know who is responsible for this debacle. The Palm Beach artificial reef is now completed. 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? If Surfrider and others haven't done it already, my view is that Swellnet, as a legitimate media organisation with a substantial subscriber and stakeholder base, could very reasonably write to both the NSW Coastal Council and Sydney Coastal Councils Group seeking advice about the adaptation options and why buy-back was not considered suitable for the site. The also don't grow in sand so they won't be of any use to prevent coastal erosion on our open-ocean beaches. 2 metre swell at 13 seconds combining with a 1.8 metre high tide at nearly 9am should provide some good viewing this morning. It's going to be carnage there this morning & yesterday afternoon even, solid 6-8ft sets on a big high, anyone heading down for a look? Nobody there is in a position to offer 2-3 times market value. I wonder if they're intended as some kind of device to absorb/dissipate energy rather than as trafficable stairs? Apparently there was a buy back scheme that faltered in the early 1980's when the department of public works ran out of money. The sheer number of cables there suggests to me that an offshore reef proposal would be unsuccesful. The UNSW Centre is called the Water Research Laboratory. Its a wicked problem theyve got, in the true sense of the word.. Hence, they are of no market value to me. Could be the camera angle but. The contractor is required to remove this temporary working platform and bund at the completion of the works, sieve the sand and remove all debris, and return the beach to its former state.. The problem is one of vertical fiscal imbalance. Plop! Dont lynch me its only an idea. These impacts would have been explicitly tied to that particular design option by the engineers and other specialists involved. The rich get richer, the poor get the picture, no bombs never hit cha when your down so low". It will improve beach access. Has any one ever suggested an off shore reef, seems like a win-win or is the sea floor unsuitable? It's only a temporary feature. People need to be absolutely on top of the approval process in their local area if they want to have a hope of preventing these structures. The NB has always excelled at extreme ugliness. The Collaroy seawall was in part constructed after a significant storm event in 2016 eroded 50 metres along the Narrabeen and Collaroy shoreline, causing damage to waterside properties. The very thing we live for one the beaches is full of concrete and man made fuck ups. Fvck the coastline. A horizontal reef is also a "Hard Structure" yet it acts in a very different way to a Vertical Sea Wall such as the Collaroy one. Should this critical lens be applied to other topics such as the Coolum wavepool? This strategy had been used in other parts of the world where poor planning placed buildings too close to the ocean. When deciding to spend rate payer dollars, on what metric do they use without using the big IF ? Sounds like you are pretty deep in that world! This isn't a new issue, as has been mentioned in the article above, and the longer we ignore the elephant in the room the harder it will become to resolve. These seawalls are easy to design, and easy to construct. They have just completed digging out a new path for the river to follow with excavators and every day Id watch the next morning after high tide their progress would seem effortless and the river would tend to follow the old direction. In the end it's all pretty simple though, as most beach erosion of consequence is caused by large/powerful waves. 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? I suspect the engineering report will say thatif we ever get to see it. Northern Beaches Council are the biggest tossers ever. Last Wave inalways team up with surf buddies to safely exit yer local Seachange Monstrosity. I imagine the ocean will eventually claw away under and around and over the structure. Tonights high tide is 1.34m, tomorrow morning is 1.96m. It would be fantastic to see an interview with someone from Many Hydrolics as they did all the Scientific modeling and have been very open in sharing their data. Step 3: Calculate the number of pilings that will be required. Sounds like the beach will be off limits/ too dangerous to walk on for weeks until the NSW Beaches Council recovers the rusting rebarb & concrete waste scattered along the beach then? Engineered to Australian Standards. Climate projections will have some Australian surfers rejoicing, and others not so. I wrote to Many Hydraulics Laboratory to ask for the details regarding the sea wall assessment they produced. Bullshit. check out the beach erosion in Apollo bay as well Actually I do understand why the council doesn't research an alternative to a concrete wall, because it's easier to build a wall, something humans have been doing for thousands of years, we're good at it. These very costly bandaids never work and continue to fail while extending the problem to adjacent properties that don't have the wall. Unlike politicians, scientists are usually very open with sharing their knowledge and data, to help inform the public. Therefore, the group of Narrabeen and Collaroy residents are not successful in addressing the issue of coastal erosion. In the other pic you can see the completed section of the wall. What a pity as the potential for offshore reefs around there is really good. Picture: Nearmap A subsequent image of Collaroy Beach from June 8, 2016. Kimura (2016) "When a seawall is visible: Infrastructure and obstruction in post-tsunami reconstruction in Japan" Lance Knight. https://www.linkedin.com/mwlite/in/peter-horton-coastal-engineer. 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. The whole buy back argument being too expensive is a crock of shit. Planning Minister Rob Stokes told the Telegraph there was a recent plan to build a sea wall in Collaroy at the scene of the devastation but the owners would not agree on making a contribution, so it never happened. There are some fed govt areas that listen to this thinking. I am safely 140m above sea-level now so that should be safefor a while hahaha. Im not trying to be a dick about it. Or are they just doing it like politicians and getting consultants to advise them and simply ignoring it and doing what they want as they are not bound by law to take that advice. Get Pro. But, they just persist time and time again. It appears that because of the relative lack of access to PC, the equation would be out of kilter to begin with. 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. Cyclonic activity isnt forecast to increase at all - I think the jury actually out on that at the moment, east coast of Australia in a 500 year dip too on cyclonic activity. "Environmental vandalism or gross negligence?". Collaroy resident Tony Cagorski lost more than 10 metres of his yard during the weekend's wild weather, undermining the foundations of his home. Well, it (and a lot of us) could possibly be in for a real test within 3-5 years with the Thwaites Glacier (Doomsday Glacier) suggested to be at risk of sliding into the sea and potentially raising sea levels by 65cm. First and foremost they say It's for erosion control but as you've seen after 2011 they did pretty much sfa. Theyre only a couple of hundred years away from It shows how different combinations of coastal defences and wave and tide conditions affect overtopping and flood risk. The Collaroy seawall was in part constructed after a significant storm event in 2016 eroded 50 metres along the Narrabeen and Collaroy shoreline, causing damage to waterside properties. Just look at the surfcams tommorow morning, will be another case of ugly easterly that will make problems worse.
