The state government and council are together tipping in 20 per cent of the costs for the construction of a wall stretching from Collaroy to South Narrabeen after heavy surf and powerful storms . I would rather have seen the money go into a couple of California style piers. That's so shithouse I don't know where to start, Zen. I am pretty sure the link was correct when I posted it. which is why the video is so interesting. The total contribution of both the Council and the State is $3.46 million, which is 20 percent of the total cost of construction. We had made a big mistake that would become bigger. Yes, blowie, I've yet to see anyone our age advocating for a soft solution. Hi Lost, yes there is another option - see my 2 posts above. Premium ad-free surfcams, dawn surf reports, and more had been lodged 18 months earlier in July 2018, http://www.irjes.com/Papers/vol6-issue10/F61012431.pdf. When the CBA or risk assessment work is done with good information about the things to be lost (eg the beach, public access, amenity, etc) it can shift the outcome of the analysis significantly, particularly the "do nothing" which is actually doing something. There is a common denominator here, "Coastal" engineers with a lack of knowledge and understanding of coastal processes. For those who may not know, the private land issue is complicated in NSW in particular (less so in other states) by the existence of ambulatory land boundaries which are set at various levels of the tide eg mean high water. No more excuses for your terrible workmanship anymore. 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 . We all have valuable opinions, but they need to be separated from facts at all times, especially when it comes to Journalism. as my old mate hutch likes to say. I guess that the levees will give me a 100% guarantee that it'll never happen in my lifetime". In one of the pics you see plant equipnent tearing up the beach in preparation for constructing a wall. There are some fed govt areas that listen to this thinking. "There's no sense at all in building something like this from an engineering perspective. Could be the camera angle but. Indeed. 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! Lets bring it on. It's actually quite simple to install and get going unlike a lot of open-source software. 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. For example, during sunny conditions in Collaroy beach, constructive waves transport eroded sediments from cliffs and headlands to build up the beach. Here's the full video with audio. Not sure how they would fix them to the sand though. Men sand-bag properties on Collaroy Beach Arlington Building and a run of houses to the north circa 1922. It shows how different combinations of coastal defences and wave and tide conditions affect overtopping and flood risk. 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. Council and State Government contribute 10% each. Instead they provide a caveat for bulldozing sand from low on the beach to higher on the beach in times of heightened storm activity - which only lowers the beachs natural defence system. I suspect the engineering report will say thatif we ever get to see it. Some family recently went through this as their house sat above the construction zone for the Spit / Northern Beaches Link tunnel. Establishment and set out of site survey control points. You may not realise that there have been large volumes . You have a decade of good conditions somewhere along the way and everybody builds on the beach or on a river bank and then there reminded of the risks being swell generated by a low and annual big tides in cyclone season who woulda thought ..or flooding by jingoes fuk wouldnt you rather walk an extra couple of hundred metres and leave nature to do what it does . stupid white poeple ..classic. Cheers for the knowledge Craig. I'm a huge tree-hugger but they will not stop powerfull ocean waves. 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. They have just invested in an asset that requires 60 years of maintenance. The erosion at Collaroy/Narrabeen Beach is not particularly significant, unusual or surprising. Protesters linking arms on the beach in 2002. Holds more water and replenish the beach? At the same time it would put an end to the constant dredging and relocating of sand from Narrabeen Wow Zen saw those photo's , it's really sad that they couldn't come up with something else , which raises the question.what other alternatives are there?? Its brutalist engineering, says Gordon frankly. Another week, another pumping day in the south-west of France. That's the only thing stopping all the sand at the base of the wall getting washed away. You wouldn't accept that in a bridge from an engineer, so why accept it in anything else? they might be right basis forecasts but beachfront owners bought in an area that didnt previously exhibit high erosion issues. For some it. That means that the Feds have all the money, the States some and the councils bugger all. Its no wonder the climate brigade aren't on board telling us all there garbage but erosion been around a tad longer than the 80s. The majority of these companies are legitimate businesses set up by Yakuza. But there will also be a range of other social and environmental grants on offer that the LGA will use to leverage off for on-going maintenance. >> and the ocean will wash it all away again in the next big swell. There's been significant coastal erosion (acute) along the GOR in recent years, though only a handful of places have experienced coastal recession (chronic). It breaks my heart. I was watching the houses on the cliffs at Bilgola the other day. The politicians and land owners actions are an entirely separate discussion and I'm not entering into that minefield! If you are referring to Vertical hard structures then that needs to be specified). The Gold Coast has undoubtedly the most at risk coastline in Australia. Will this mean sand depletion north and a build up south? Your browser has JavaScript disabled. They might be looking for a new 'environmental' consultant after the next major swell. Yep, prevents over-topping but how's the reflection and enhanced rebound wave back into the surf zone!? 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). The co-founder of Ksubiis to launch a '70s surf-inspired hotel on New South Wales' Mid North Coast. This is where I live. Hopefully there's someone with deep pockets able to go after the truth of the matter. 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. 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. RAW footage from this week's extra-large swell at Peahi. 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. High rise apartment buildings demolished when they realised it was the most cost effective and environmentally sound long term solution. Stupid dumbfucks. I recently moved house [Northern-Rivers nsw] and seal-level rise was a very serious consideration of mine. I wonder if they're intended as some kind of device to absorb/dissipate energy rather than as trafficable stairs? As I understand it, governments have been reluctant to purchase vulnerable properties because there will be so many of them and the public purse could never afford it. 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. Hey BD. Ha! The Collaroy Beach coastline on May 6, 2016 before major storms swept the shoreline. Link any useful papers youve found. Cheers. Between these three, you can protect any shore from water erosion. It is a difficult and wicked problem. Good point, however wouldn't a potential buyback theoretically drive the price up? Proven time and time and time again that sea walls do not work- period. 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. Thanks Craig aod if you are THE Jody P, yes you are a ledge. Here are the bloke credentials Not off topic JS, wouldn't be surprised if there is a hyperlink to that video in the sea wall approval document!. 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. First and foremost they say It's for erosion control but as you've seen after 2011 they did pretty much sfa. lilas Manly Hydraulics did the work which was used for the initial design but I am not so sure about their input on what was finally constructed. Shop unique custom made Canvas Prints, Framed Prints, Posters, Tapestries, and more. Preparation of sea wall GPS file suitable for upload to GPS rover or machine guidance equipment. 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. Mentioned in a previous article (linked below) - the region hosts submarine cables, so it's part of the Northern Sydney Protection Zone. Furthermore they have facilitated an increase of erosion to adjacent beaches. This just a year ago was a nice Sandune. Yamashita (2020) "Living together with seawalls: Risks and reflexive modernization in Japan". Futile. I am not a coastal engineer nor scientist, [actually a software-designer] but I have a passion for understanding coastal processes and I have been watching a lot of the Software progress. Our services included: Pre-Work Detail Survey for existing surface levels at design chainages. San Sebastian surfers are fighting a wavepool in their hometown, which is also the hometown of Wavegarden's founder. Im just saying its a difficult issue, beachwall terrible and if its sets a precedent huge chunks of the coast stuffed. Large waves have a lot of energy and must be forced to break further out to sea to dissipate the energy before reaching the sand shoreline. As the article states, in terms of erosion, vertical walls don't work and actually exacerbate the problem. Hear, hear! They are a method of hard engineering. 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. Unlike other approaches like soft beach nourishment, they offer a long term solution to shoreline erosion. Def landing size incorrect i reckon900mm min ? Point being that the experiment is a gimmick as it would be quite easily modelled in a software program given all geometric surfaces and the regular wave pattern. I think the re-sale value of their properties trumped their ability to access the from their back garden. 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?!! From deep state secret spot to modern media darling, what lessons can we learn from Cape Solander's evolution? Ocean Pools > Skate Bowls > Wave Pools > "Boomer'z Backwash Booger Bowl", Crew requested the Turning Japanese Tool Box, History of Collaroy Erosion / Wave Pools / Tow Surfers. 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. Angus Gordon, an engineer with fifty years experience in coastal engineering, assumed the same. Again this can only be taken as opinion without proper scientific references. In the other pic you can see the completed section of the wall. Some investigative journalism required to obtain all the council documents around its approval process. Usually done by compulsory acquisition with the government working off existing market prices. Owners of storm-devastated Collaroy properties on Sydney's northern beaches face paying up to $140,000 each for a new sea wall that might have saved their homes had it been there at the weekend. Posted the story from that link here. "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." 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 option of do nothing seems to have passed but it can always be thrown in as a baseline. A barrier reef in place would no doubt have knock-on effects. If they fall into the sea so be it. Yep need to see front on pic The sheer number of cables there suggests to me that an offshore reef proposal would be unsuccesful. I have the mhl report but cannot find the link again. 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. processes currently-exported iron ore, bauxite, and alumina into green. Any example around the world that have worked with out wrecking a beach but holding back erosion in built up areas ? The 18-year-old scored a near-perfect 9.50 in the Final, held at Seaside Reef in Encinitas, California. and I live 8 hours away. If you look at the photo of the wall there appears to be a set of stairs built into the concrete for each property. Hi Craig, the short answer is I'm not sure as I have been out of NSW too long. If anyone was to slide down the edge during one of these high-tide swells there would be a high chance of being washed off their feet and dragged out to sea. Stop wasting money and do something that will achieve the intended goals. It is all about the road. The Local Government Act allows the council to set a special rate to pay for that. Moreover, the current DA makes no mention of sand nourishment from sand sourced elsewhere, such as deeper water offshore. "Once this is up it'll be a momentum for others to do it too," said Orth. Lol. At what point do we put an end to this insanity. Yulex geta second chance at a first impression, and this time they makeit count. Just like when the stock price of a company increases because of a speculated takeover bid. Mr Horton said there has been some very minor erosion at Collaroy/Narrabeen Beach this week, along with other NSW beaches, but it is not a cause for concern. The sea wall forms a permanent, stationary barrier between the sea and the land. [happy to stand corrected on any of this] "Protective works are a far preferable measure to a vertical seawall," he said. 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. And thats being generous. exports the same quantity of energy in green electricity and hydrogen as it exports in thermal coal and liquefied natural gas. We can mess things up in a colossal way, and then keep doing it repeatedly. The Surfrider Foundation Australia organised a protest against the seawall that is being erected between Narrabeen and Collaroy. It would be fascinating to see the NSW Cabinet documents which advocated for this approach. Inevitable as the ocean winning, is a painted "cock and balls" on that wall. Not every beachfront owner is a cashed up prick, some have been there 50 years when climate change etc wasnt on the radar. 42 online submissions ALL supporting the wall but many seem to think it would be a sloping rock construction. And find outwhy you'll soon hear a hell of a lot more about them. "Have you ever seen such a magnificent view as the one from our balcony overlooking this active volcano? Sorry to sound pedantic but we should clarify exactly what we mean by "Hard Structures" as it's too general a term. To my way of thinking, and with a working understanding of government process, the real issue is the approval process. And cap prices for market value pre 2000. "We haven't had a flood here for 20 years you say. Unfortunately, what we see in Collaroy might become a norm to protect this lifestyle. [ask GaryG] Just ugly, clog up the waterways etc. 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. The second DA is now here. Vertical Seawalls Vertical seawalls are exactly what you think. Old dude making a dash for it, budgie smugglers and a cricket cap. 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. When deciding to spend rate payer dollars, on what metric do they use without using the big IF ? Basically the awarding of contracts falls across a couple of ministries. Yea I agree with this. The beach has remained under threat since that time, with additional erosion occurring during subsequent storms. 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. Collaroy Sea Wall With such close proximity to the ocean, our client tasked us with producing an alternative to the commonly used polystyrene forms. https://www.facebook.com/watch/?v=144437777895204. Where the only issue is private property things are a bit simpler. Any system that affects the coast from a different angle upsets the balance of that orientation and the system then takes considerably more time to re-adjust. https://www.dexpan.com/pages/how-to-use-dexpan-break-concrete-rocks-easily. Having said that, nature usually finds a way to overcome most "permanent" human structures, and they often seem to forget that the wall isn't continuous.yet. For me, the value of these properties is in the negatives and at the very least, its a big fat round calamari. Wetsuits may never be the same again. walkways to viewing platforms & beaches, selective weed management, planting, education, etc), Give nature a chance, it will rebound & stabilise dunes or else find a new equilibrium.< inland. 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. For the most part I understand buybacks but, how will they appraise the value of these properties? 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. Imagine the carnage during the next ECL. I doubt there will be a demand for the effected given the inevitable. Who could forget the MOLE building or the spoil from the North Head Sewage Works tipped over the cliff? @Tango Pipeline specialist injured while duckdiving in heavy waves. 314k members in the sydney community. These contracts to the construction companies are worth hundreds of millions of dollars. Surely going to get all crazy reverb and backwash stripping their sand more rapidly as well. https://www.celeria.org/ Get access to long-range forecasts, hourly graphs and ad-free webcams. This can easily be achieved by creating offshore reefs that reduce the energy to a level the beach can cope with. 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. I looked into this again yesterday. 2 metre swell at 13 seconds combining with a 1.8 metre high tide at nearly 9am should provide some good viewing this morning. What they fail to mention is the massive corruption that's involved in awarding these contracts and the fact that the construction companies themselves for the most part, are predominantly Yakuza. At what point are they a write-off? The beginnings of a huge $25 million concrete wall in Collaroy on Sydney's Northern Beaches. No fuckers complained about the rebar reef. The local community group has been protesting against a seawall for almost 30 years. It certainly doesn't make it the best decision though. besides Id rather just shout at my computer. NewsDNARaw. If you look a bit to the north you can see the relatively intact beach with a decent amount of sand. 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. They have destroyed every built form on the beaches. Thats just a done deal. 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.. Will it make Carties better or will kooks just ride into the wall even more. However, while they prevent further shoreline erosion, they do not deal with the causes of erosion (French, 2001). It never stood a chance. Im not trying to be a dick about 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. Are the exposed quarried rocks part of the construction/ foundation or are they from pre existing efforts. 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. (btw if you're the Jody P I'm thinking of, you're an absolute legend mate!). Its like stepping forty years back in time. Perfect future film location for backwash kook of the day. Bean counters at the local council know this too. >>Is that because he has been paid already?? Here's the Maritime Safety Queensland website link and here's what appears to be the numerical modelling report upon which a lot of decision-making on the issue is based. The council will buy me out at any price if things get too hot". The whole buy back argument being too expensive is a crock of shit. 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. Can somebody please sack almost ALL so called coastal engineers for Fuck's sake! Please enable it to continue. It has to be worth a look.
