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. It's been seven years since the last, but the event has been called on off for this Wednesday - Hawaiian time. Between these three, you can protect any shore from water erosion. 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. 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. That is the most ridiculous thing I have ever seen, hope they don't actually use that pathetic demo to help make a decision on what is going to be built to stop erosion. The very thing we live for one the beaches is full of concrete and man made fuck ups. At this point, the relocation business case doesn't seem to stack up. Plop! The wall is set to be seven metres tall, but three-quarters will then be covered by sand brought onto the beach. Lindsay Fox is happy as a vegemite as he now has what he wanted all along, more real estate to land his helicopter on. Northern Beaches councils have been sacked for dodgy dealing twice before. Such a shame its job wasn't to conserve the beach and public access at the same time. Contrast man-made against a natural barrier like mangroves (apologies for the sound, not my video), Trees work well for preventing erosion ONLY when the wave power is very minimal. Northern Beaches council has received a new application by five local property owners to build two new sections of the wall in front of their properties to protect the homes from coastal . Here Willi. . They may have a wall, but there will be no beach in front of it. This is associated with above-average wave heights related to Tropical Cyclone Seth and also elevated ocean water levels associated with very high tides, Mr Horton said. increases social amenity". Preparation of sea wall GPS file suitable for upload to GPS rover or machine guidance equipment. Kook survives a brutal seawall bashin' well almost! The majority of these companies are legitimate businesses set up by Yakuza. 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. "Brendan Donohue, President of Surfrider Northern Beaches, has been talking to us about their famous Line in the Sand protest against the Collaroy/Narrabeen Seawall 18 years ago and we are very excited to replicate that campaign on the Central Coast in the not-too-distant future," Phillips said. 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. 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.. Yes it is. "Protective works are a far preferable measure to a vertical seawall," he said. Interesting to see if the slowed (design of) sand migration has had any knock-on effect for the likes of Tallebudgera- Burleigh and beyond. (As we all know, unfortunately, money/wealth/property seems to be many people's priority, and corrupt opportunists step in to "help" with that). For the swellnet readers here's some background info, and here. 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. Including the residents behind the great wall. I'd reckon the road, arterial services (electrical, sewerage, etc) and the houses all factors. It's folly to believe you can hold back the Pacific. Fight the good fight mate. 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. 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." I think the re-sale value of their properties trumped their ability to access the from their back garden. A "macabre" scene greeted surfers followinga mass kill of invertebrates. Lance Knight. I liken it to a form of gambling. Holds more water and replenish the beach? As hostile native rescue party moves in for the killOh the Humanityreads Humilityreads Kook! which is why the video is so interesting. I looked into this again yesterday. 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. RFS DU SOL's new album cover to Surrender is on point.. Collaroy sea wall 1.8 mts higher than the Berlin Wall https://i.imgur.com/DuHM6zJ.gifv Thanks BB. Death of Her Majesty Queen Elizabeth II. The also don't grow in sand so they won't be of any use to prevent coastal erosion on our open-ocean beaches. For example, during sunny conditions in Collaroy beach, constructive waves transport eroded sediments from cliffs and headlands to build up the beach. Is it designed to behave like a bottle-neck? Yep need to see front on pic We had made a big mistake that would become bigger. The exception of course is if youre a donor to the LNP then a $3M block of land can be sold for $30M!!! Yeah nah. Rock barrels at its best! Completely agree that not all beach owners are cashed up pricks. As you know we have the Great Ocean Road down here , which was a huge Tourist attraction ( before Covid.) they might be right basis forecasts but beachfront owners bought in an area that didnt previously exhibit high erosion issues. Im presuming that sand delivery's from the lagoon will be an ongoing thing. Of the people that Swellnet spoke to, the opinions of how we got to this point swung from nefarious (It was rushed through during COVID because they knew people were occupied) to inept (It was signed off by a mid-level planner with no knowledge of coastal processes). We have summarised some key facts about the first of the Collaroy owners' seawalls. 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. 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. Also, it's a not so secret secret, anyone who speaks out about this have been known to disappear. Its brutalist engineering, says Gordon frankly. Statements such as the two below can only be classified as opinion unless you link to references. 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?!! I've looked at the general location plan of the cables and it seems there is a good say 500m- 1000m distance between groups of them along the beach, and they are buried for the first 500m out from the shore, so I would say there is a good chance of working within those areas in consultation with the cable authorities. when roads and buildings are about to fall into the sea. And without getting too political its a good chance that the persons who own these properties will be liberal voters so called free marketers who abhor the intervention of government in their day to day life.. except when it concerns their interests.. Nup it is anchored to the bedrock. Ignorant clown" 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. I think this was done for the first DA, the sloping rock wall, rather than the vertical one that was actually built. Climate projections will have some Australian surfers rejoicing, and others not so. A man whose million-dollar beachfront property on Sydney's northern beaches was damaged by king tides says he and his neighbours are happy to chip in for the construction of a sea wall. And this is on a small, weak windswell from the south-east. 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. Whether concrete castles or sand castles, buildings that close to a sand shoreline must be living on borrowed time. Looks perfect for high tide backwash to spread up and down the beach. Joint Venture adopts new name, Te Puna Aonui. This would reduce the lateral movement of sand along this stretch of beach, reducing the natural erosion while creating some great banks. A barrier reef in place would no doubt have knock-on effects. I've got a mate who works for MHL as a coastal engineer. 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. 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's the full video with audio. As far as I know their job was to asses the designs given to them by the Coastal engineers, not to actually create any designs. The point i guess im coming to is, and i know an old couple whose property is very exposed to this issue, who have lived there since 1960's and are now in their 80's and likley won't see the impeding issues in their lifetime - but really they have done nothing wrong, bought an old shack in a place they love when no one lived up here, I wouldnt say there are a lot of people left like that but there are a few I know up here a version of that and the whole "screw those rich pricks" mantra is just divisive. After five years and four contests, the performance level at Kelly's Hot Tub hasn't evolved but instead gone the other way. Futile. Not to mention the many brutalist houses dotting its once beautiful headlands. The process is cyclical, however short-sighted development upon the foredune, built during times of a wide beach profile, impedes the system. In their natural state, sand dunes are dynamic and in a constant state of flux. Links relating to the City of Sydney, and NSW in general - please read our rules before And thats being generous. 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. Apparently this is just one part of the seawall. It ran northwards around the back of the lagoon and on toward what is now Collaroy Beach. nothing that a annual maintenance fee paid for by the taxpayer can't fix. My experience is that if the responsible authority wasn't involved in the valuation process they struggle to comprehend it, let alone see how it legitimately applies to their own patch via things like benefits transfer. I will check with him and report back. This can easily be achieved by creating offshore reefs that reduce the energy to a level the beach can cope with. btw- that one is a tiddler compared to what they have here. a report a number of years ago by the Great Ocean Road Coastal Committee, GORCCshowed there were more than 47 areas that were of immediate concern where the ocean would cut the road. I do know the metro area was excluded from the NSW Coastal Policy for a long time because it was seen as too difficult, and that the CLPS was focussed on environmental values. So says Brendan Donohoe of the conundrum facing Northern Beaches Council in relation to the Collaroy beachfront. Can't understand why more engineering research isn't focused on solutions further out in the water to dissipate the swell energy before it reaches the shore at full speed. To add a bit of controversy, I've often wondered: Is Carties borderline just a novelty wave? That's so shithouse I don't know where to start, Zen. The thing is, the existing site was fine except a motorway was about to be built straight through it. Hi Lost, yes there is another option - see my 2 posts above. Newiie Harbour was pumping. 100% agree Craig, the only option is to buy back the properties and be done with it like they should have done years ago. While celebrating his record for coastal protection with a park on the Collaroy-Narrabeen stretch, Northern Beaches council was also processing a Development Application thatd threaten the very same beach. There are three main types of seawalls: vertical, curved, and mound. Construction of a seawall is underway to protect homes at Collaroy Beach. 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. This is very different to Collaroy. A development application (DA) before Northern Beaches Council would see two additional sections of vertical wall built 50 and 30 metres in length straddling the South Narrabeen Surf Club. My experience with compulsory acquisition had to do with a Sydney motorway a few years back. Has any one ever suggested an off shore reef, seems like a win-win or is the sea floor unsuitable? It certainly doesn't make it the best decision though. I no longer live in the area but just can't believe it has progressed so far without anyone noticing. Here is the DA for the wall. I recently tested an Open-Source Wave modeling software called "Celeris" and the result are really good although I didn't go too in-depth with it. And I previously worked in a firm that did work in this area (it's not my specific expertise but I get the broad concepts). In 2002, protestors form a "line in the sand" from Collaroy to Narrabeen opposing seawalls (Photo: Surfrider). A band of knowledgable people have gotten together and are in discussions about it and coming up with arguments and alternatives against it. That's the only thing stopping all the sand at the base of the wall getting washed away. the hardest decisions should be the easiest. All the reaserch I did seemed to show that the headland affect and beaches just north of those headlands, i.e. Damaged houses and a collapsed swimming pool at Collaroy beach after waves of up to 8 metres hit the coast on June 6, 2016. The angle of any hard hard structure relative to the wave direction is what really matters, so you can see why it's important to be very specific when talking about science/engineering. Collaroy sea wall. Im not trying to be a dick about it. That's the most sensible thing I've read so far. Alas this would have meant some loss / damage to private property. I tear up and swear to myself. The role of the council in all this might come out if people push hard enough. It would be a good idea to put in a surf cam in that pans up and down the wall to document any changes to the beach, sand movements, erosion problems etc. If they approached the landowners then the most they would be offered is market value. The only place for a residence next to Narrabeen Beach was up on the headland. and the sick irony of the beach access sign detailing the seawall works with all "enquires to be made I wouldnt have thought there would be much fetch? The seven metres protruding above sea level is vertical, even going beyond vertical for the final metre to prevent wave overtopping. I'd imagine brendan and surfrider will have that covered. did depend a lot on steepness of the beach etc. Sorry to go hard on your story like that but I feel we need to keep the science at the forefront of all coastal engineering discussions. Theyre only a couple of hundred years away from Yep. Yep, basically pork-barrelling on a massive scale and the Japanese sold them the lie too. (This statement also doesn't specify what type of HARD structure. 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". Brendan Donohoe says the beach has been "permanently disabled. Yes and do they have tactile indicators in the correct place? I think they would be very happy with an ugly seawall. 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? 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). 2 metre swell at 13 seconds combining with a 1.8 metre high tide at nearly 9am should provide some good viewing this morning. 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. 2)How much did the Collaroy Carpark Coastal Protection works cost? I am working on a gipa application to try and find out what community consultation they did for the second DA. 2016 Collaroy seawall Concept Design Specs These very costly bandaids never work and continue to fail while extending the problem to adjacent properties that don't have the wall. Seawall construction isn't mentioned. Ignorant clown. Wetsuits may never be the same again. These contracts to the construction companies are worth hundreds of millions of dollars. One thing about mankind. This clearly did not happen at Collaroy. You can go to court to complain about the price, but you cant object to the acquisition. Im sure Fraser Island will give some back.. Heard rumours that the Wamberal Seawall has got green light hopefully the central coast council read this article. Not rhetorical question ! I don't disagree with most of that. BB has there been any attempt to take the process to the Land and Environment Court? Hence, they are of no market value to me. Hopefully there's someone with deep pockets able to go after the truth of the matter. These impacts would have been explicitly tied to that particular design option by the engineers and other specialists involved. Really interesting [and sad] to see this story progress in real-time. 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. 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. Should have taken the high road. Guess where that temporary rock wall has ended up! Hey there - well I live in Noosa, Sunshine Beach specifically. The houses up the dune with no apparent erosion would be an apple compared to these lemons (for now). It's like companies using buybacks in a crisis. The State Government essentially provided the compensation for the business to relocate to another 'suitable' site. Seawalls have the inevitable effect of reflecting and concentrating wave energy and accelerating erosion. The above video might be of interest to help understand the design of the wall. Inevitable as the ocean winning, is a painted "cock and balls" on that wall. As the article states, in terms of erosion, vertical walls don't work and actually exacerbate the problem. Both!! The legacy of that approach will be something future generations will have to live with.. Willi, how would easterlies impact the Great Ocean Road coast? Its also been the focus point for opposition to coastal development; an abject lesson about what results from bad policy. Kimura (2016) "When a seawall is visible: Infrastructure and obstruction in post-tsunami reconstruction in Japan" There are 11 parcels of public land (including the Collaroy carpark, South Narrabeen Surf Club, reserves and road ends) interspersed between 49 private parcels of land that require protection. Collaroy's existing situation is precarious at best. Construction costs are 80% homeowner funded. There's only a loss to be made for the purchases. That's crazy stuff. It just doesn't make the engineering firms any money or contribute to gross state product under the current economic system. Usually done by compulsory acquisition with the government working off existing market prices. I guess that the levees will give me a 100% guarantee that it'll never happen in my lifetime". However, the bean counters and quantity surveyors were extremely difficult for obvious reasons. 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. nothings going to stop him on his daily dip. On the MP they blew the heads up and the erosion from Portsea front beach to the heads is crazy. They were concerned the sand directly in front of the seawall would be washed away, eroding their beach, and, on Tuesday, that's exactly what happened. Multiple reports have previously shown a better cost effective way to protect public infrastructure on that stretch. They are the real villains, as regardless of what anyone says or does, these idiots can allow or disallow engineering developments so the buck stops there! Not even the dude came up with half an ear! So where public assets like roads are involved things get really sticky. The matter is currently under investigation by Environmental . The whole buy back argument being too expensive is a crock of shit. 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. Though still in its early days, the reef - which cost $18 million - has maintained beach width since it was completed in 2019. Has been for a while. Instead, sand nourishment is the popular solution to maintaining beach width, though both Donohoe and Gordon are feeling once bitten and skeptical of any council promises. https://eservices.northernbeaches.nsw.gov.au/ePlanning/live/Public/XC.Tr First red light! Picture: Nearmap A subsequent image of Collaroy Beach from June 8, 2016. High rises to sea walls. Those first couple of staircases looked fucked. I wonder whats worse this concrete monstrsity or the digital identity certifcate which is about to be become a reality unless you put some energy into being another voice presenting a social inclusivity rather than If there is an identity card, then people in authority will want to put it to use.What is at stake is nothing less than the nature of our society and the power and authority of the state over the individual. I also presume the view of the houses will be enhanced by the no trespassing signs in large red writing. This widely publicized protest was an attempt to promote a pro-democracy, civil liberty, social justice message, and to protest against corporate greed and economic inequality. Existing market value must take into account that houses have erosion problems. More than double in wealth the last 7 years. I can't believe that those structures have been built in 2021 and that the legislation still hasn't been amended to counter the property rights of the owners. Great stuff. They needed see this, but still probably wouldnt t have believed it. Same stretch of sand - another wall to protect public assets - https://www.scs.nsw.gov.au/soil-conservation-services-projects/collaroy- Gary G has been erecting hard structures in the dunes around Victorian beaches for years. We have the tools and imagination to manage the climatic challenge that beginning to show in my lifetime. 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? I am not stock market savvy. Would be very interested in knowing what other options were considered and why they were discarded Yeah it's easy to get caught up in the house situation, but the road is at exactly the same height and built on sand too. what's the logic/law in having to buy back the properties ? If so, I presume it may slow around the reef, but then continue north on a more normal migration speed. A seven-metre high wall erected to protect beachside mansions from being washed away has sparked debate among locals in a wealthy Sydney suburb. We have over 40 years of combined experience installing, maintaining, and repairing seawalls on both residential and commercial properties.
