buzzwords include "Improved recreational access. " This process must require wind over thousands of years but people and waves stomping over dunes seems like any dune system near a popular town once destroyed wont come back? 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. Also I'm suspecting at the lga level the up front investment to do this work can be a hard sell. The devil is in the detail and the more we understand the science behind it the better. 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? Edit: The estuary was in an area protected from the ocean and the cliffs only faced small wind chop and the tides. check out the beach erosion in Apollo bay as well "When a hard structure is introduced to the equation we see an increase in reflective energy and turbulence, slowing the accretion of sand while also accelerating erosion in storm conditions." Well go for them, put in your FOI requests and prove what we all suspect; that the council turned a blind eye to save themselves some money and appease a noisy minority. Same old issues, with a more educated market. as the article states coastal erosion has been known since the 20s in that area and has been studied meticulously ever since. I wrote to Many Hydraulics Laboratory to ask for the details regarding the sea wall assessment they produced. Lindsay Fox is happy as a vegemite as he now has what he wanted all along, more real estate to land his helicopter on. Our services included: Pre-Work Detail Survey for existing surface levels at design chainages. There are three main types of seawalls: vertical, curved, and mound. Good point, however wouldn't a potential buyback theoretically drive the price up? My 2c on the buy back scheme - NB Council won't have 50+ million sitting around to buy them all back at once (and NSW Gov wouldn't be in a hurry to give them the rest) so they'd have to do it say a couple per year, but at the same time, that leaves the others who can't be bought back vulnerable and at risk of further destruction if another mega storm decides to show up, which in the current climate you'd have to think is pretty likely. They are a method of hard engineering. When deciding to spend rate payer dollars, on what metric do they use without using the big IF ? The council will be the lone 'interest'. This sets a very dangerous precedent for the rest of NSW. A number of properties along the oceanfront from Narrabeen to Collaroy were seriously endangered by erosion during a large storm swell in 2016. Would be really good to see an article on the current state of affairs in the Coastal engineering world. After five years and four contests, the performance level at Kelly's Hot Tub hasn't evolved but instead gone the other way. Sorry to sound pedantic but we should clarify exactly what we mean by "Hard Structures" as it's too general a term. The theory is that the waves break further offshore, soaking up wave energy that would otherwise erode the leeshore dune system during storms. I imagine the ocean will eventually claw away under and around and over the structure. I'm invested now, and want to know the latest. That's appalling if it's the case, BB. I posted links to the relevant council pages in the previous story. The wall is set to be seven metres tall, but three-quarters will then be covered by sand brought onto the beach. 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. But, they just persist time and time again. 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. 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. I suspect the engineering report will say thatif we ever get to see it. Picture: Nearmap A subsequent image of Collaroy Beach from June 8, 2016. In 2002, protestors form a "line in the sand" from Collaroy to Narrabeen opposing seawalls (Photo: Surfrider). Surf Breaks Inc. Coming to a beach near you ! Another week, another pumping day in the south-west of France. 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. Yep pretty significant increase in the height. Its like stepping forty years back in time. I recently moved house [Northern-Rivers nsw] and seal-level rise was a very serious consideration of mine. How to Build a Seawall: Step 1: Conduct a thorough examination of the surrounding area and environment. 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. 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. An awkward situation, but only for one of the parties, as the Woz suspends the current Longboard World Champ. We have trouble performing numerical analysis on complex near shore environments, so what we'll do is create a slab sided wave tank with perfectly geometrical structures and wave forms and see what "actually happens". For some it. Seawalls protect the bases of cliffs, land and buildings against erosion in areas where rapid coastal erosion is beginning to pose a serious threat to. Just wondering if the stairs built into the wall are private property? It shows how different combinations of coastal defences and wave and tide conditions affect overtopping and flood risk. Would be interesting to see the state of that beach on the north side of breakwall now, This was the same dune system a few years before all these easterlies. Here's the full video with audio. Whether the NSW state government / local council want to backflip with a pike on their current failing seawall master plan is another thing. What an absolute joke of a mess this has turned into. heres a rad idea for you,dig canal from coast to central Australia which is considerably below sea level and flood the interior.could also be done in death valley USA.now that could be a wave pool!! Lets bring it on. 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 think they saw an opportunity to get landowners to pay for something that they would very likely have to do at some point anyway. The above video might be of interest to help understand the design of the wall. BB who is getting the sand which has gone from here? 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. If that was the only report they did then it would be good to know on what scientific advice, if any, they changed the plan. Separately at the Collaroy pool end of the beach when the walk way became unstable they just craned in these massive bags of rocks on top of each other and said job done - ugly as fuck. The DA for the Collaroy seawall was approved while the Northern Beaches Council was under administration. My understanding is that the hard seawall was constructed with the specific intention to protect the private property behind the wall. It would be the same as for any development adjacent to the cables where they make landfall. 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. Yulex geta second chance at a first impression, and this time they makeit count. 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. The second DA is now here. You'd think that would then open it up for more legal action (aka why did ABC get first dibs and XYZ missed out?). Yamashita (2020) "Living together with seawalls: Risks and reflexive modernization in Japan". It only does BOUSSINESQ wave interaction and NOT sediment transport but you can still get a lot of good design-feedback Initial reports claim Marcio Friere wasn't wearing an inflatable vest when he was held down in large waves. https://www.9news.com.au/national/weather-nsw-sydney-collaroy-surfer-pul Sydney 'Living' Seawalls And please take a look at all the other ridicules things Coastal engineers are doing around this country so you can see the pattern of incompetence I am referring to. Again this can only be taken as opinion without proper scientific references. Thanks again for your time and effort to make these articles, as we all truly appreciate them. 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. If they fall into the sea so be it. 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. Unlike other approaches like soft beach nourishment, they offer a long term solution to shoreline erosion. This forms a foredune and a backdude. 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. I will check with him and report back. My NSW water buddy says MHL are coyboys. Yes and do they have tactile indicators in the correct place? Where I live though the beach has no erosion issues but the council is trying curtail landowners rights significantly due to potential sea level rises combined with 1 in 100 year storms etc. The council had an interest in preventing future erosion impacting Pittwater Rd, the main north-south artery on the NB. 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. Just last March of 2019, the Northern Beaches Council succeeded in convincing the State Government to chip in on the assistance package to be given to Collaroy residents for the construction of the sea wall. 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. Links relating to the City of Sydney, and NSW in general - please read our rules before BB has there been any attempt to take the process to the Land and Environment Court? Pipeline specialist injured while duckdiving in heavy waves. 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. Nature fights back. Im not trying to be a dick about it. Great article highlighting the competing interests of the natural environment and local councils (which are too easily manipulated by wealthy stakeholders). Dont lynch me its only an idea. 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. More to come once the other residents agree to pay their contribution. I wonder if they're intended as some kind of device to absorb/dissipate energy rather than as trafficable stairs? consultant reports and community consultation no doubt funded by state money. Rock barrels at its best! Those days are gone, but we can make the future even better IF we use our brains like you say! High-quality Collaroy Beach Wall Art designed and sold by artists. 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. In their natural state, sand dunes are dynamic and in a constant state of flux. Shit.That looks like they are preparing for an invasion. 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). If you look at the photo of the wall there appears to be a set of stairs built into the concrete for each property. Apparently there was a buy back scheme that faltered in the early 1980's when the department of public works ran out of money. 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. https://eservices.northernbeaches.nsw.gov.au/ePlanning/live/Public/XC.Tr First red light! And it was created many years ago when coastal property was much lower in value and the bang for buck was much higher. Hourly Multiple Swells Wind Highlighting Model Units ft, mph. Anyone who has been to Chiba in Kanto will have seen the Tetrapod formed surf breaks there. They must only exist on a dense (and expensive) schedule of maintenance, no doubt. 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. Nah, buybacks don't put the properties back onto the market, they're acquired by the council at market rates and then emptied, returned to parkland and foredune, both a buffer against storm action. and the second last line of your article states- 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. What a pity as the potential for offshore reefs around there is really good. Spot on. And the properties either side?? 314k members in the sydney community. 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. Im not sure that councils have the legal authority to acquire the land, pretty sure that resides with State governments and the Feds only in certain circumstances. In the others, you can see a part of the wall under construction. Ha! The beach is now too dangerous to walk along and it's one big eyesore. >> and the ocean will wash it all away again in the next big swell. Has been for a while. Climate projections will have some Australian surfers rejoicing, and others not so. Surely going to get all crazy reverb and backwash stripping their sand more rapidly as well. https://static01.nyt.com/images/2017/01/28/world/28israel6/28israel6-sup https://files.northernbeaches.nsw.gov.au/sites/default/files/documents/g Basque Wavegarden Project Has Far-Reaching Implications, Watch: Ryan Callinan // Beneath A Pear Tree, Kala Grace In Dramatic Rescue While Competing In Backdoor Shootout, 'Corners Of The Earth: Kamchatka' Tour Dates, Watch: Cronulla's Jarvis Earle Wins World Junior Title. development, carparks & roads behind the hind dunes leading to biketracks, walkways, supporting the community including 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. Thats just a done deal. Click on "Documents" for the interesting stuff. Some investigative journalism required to obtain all the council documents around its approval process. Joint Venture adopts new name, Te Puna Aonui. 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. 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. My comment in the other article also notes that across this region, "it is illegal to establish, maintain or use a spoil ground or other ocean disposal point (including dumping materials at sea)". It's an interesting point whether you just blame the owners for buying a house in such a risky area and hoping taxpayers will bail them out, versus the fact that the council must have approved people building houses there in the first place (although possibly a very long time ago), "Professor Short said the council bought properties along the beachfront and turned them into parklands in the 1970s and attempted to put a moratorium on redevelopment in the 1980s, but lost its case in court.". Its also been the focus point for opposition to coastal development; an abject lesson about what results from bad policy. That this kind of construction was approved with the obvious impacts on the public domain (the beach) simply beggars belief, and the real focus should be on the process to consider the design options and then issue the approval. Therefore, the group of Narrabeen and Collaroy residents are not successful in addressing the issue of coastal erosion. Can't wait to see the classic "Dick and Balls" painted on that big ugly fucker. Seawalls of this design have been shown - all over the world- to destroy beaches. Lol. Greed and stupidity rule in councils . that would be awesome location for JOb or other jackasses to film fun vids. Its brutalist engineering, says Gordon frankly. Hey guys I need to write an informative paper based on remedial measures used to protect infrastructure against erosion. Plenty others have discussed it. Lance any surf info about Middleton Reef ? And it would also provide some useful evidence for fighting against any similar future proposals. which is why the video is so interesting. 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. If no acquisition or buyback is made, then good luck to the owners trying to sell these properties. 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. Mind you theyve only been around for a year. Further to the north, sand that was built up in front of properties has been scoured away leaving an eight foot drop-off. All the sand has moved south east where previously there were great rock lagoons there is now 100 metres of sand dunes. At this point, the relocation business case doesn't seem to stack up. No more excuses for your terrible workmanship anymore. Pipeline specialist injured while duckdiving in heavy waves. It would be possible to introduce a major sand nourishment program to move the shoreline seaward, says Gordon. What a mess. Council and State Government contribute 10% each. It is all about the road. Until then the owners can continue to enjoy their delightful seashore experience. Check this out. and I live 8 hours away. 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. The role of the council in all this might come out if people push hard enough. This would be a better solution, I think. Last Wave inalways team up with surf buddies to safely exit yer local Seachange Monstrosity. This is not a defence of the structure or the owners, just recognition that the protection of the main north south artery on the northern beaches was a factor. Mentioned in a previous article (linked below) - the region hosts submarine cables, so it's part of the Northern Sydney Protection Zone. 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. Might chat about it at some point Craig Brokensha, and anyone with deeper connections or insights, feel free to pass me their contacts and we can compare notes and research and discussion points. Rad demo john interesting as Craig said to see the changes in shock waves returning seaward. 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? "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. But thats about it . I think they would be very happy with an ugly seawall. Now a 7 metre-high, concrete, vertical seawall has been built in front of private properties on Collaroy/Narrabeen beach. The matter is currently under investigation by Environmental . I dare say the neighbours are on notice too. Looks like the council are aware of the liability concerning the still submerged rocks. they will use loop holes to ensure eligibility. when roads and buildings are about to fall into the sea. So they all get their own private beach access. In the other pic you can see the completed section of the wall. Please enable it to continue. https://www.sydneycoastalcouncils.com.au/sites/default/files/JRCorkill_A(2)_Prop_L_Rev_67-84.pdf, yes, Blindboy, I am guessing they had absolutely no input on the final [or initial] design what-so-ever as they were only used as a consulting service by the Coastal engineers. 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. Not rhetorical question ! However the short period easterly swells go straight into all parts of the surfcoast digging it up and turn almost every beach with low swell energy into an ugly mess. Isn't an extension to the Point Cartwright breakwall on the cards aa well? That means that the Feds have all the money, the States some and the councils bugger all. https://lighthouse.mq.edu.au/article/september-2021/Living-Seawalls-in-g 5 min [P] Call of the Wild skinny dip at yer local Sea-Walljust doing wot comes natural! Owners, Council and 'engineersshame shame shame. This is the only plausible outcome from the hard seawall construction and the engineers would have known this. 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? 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. Protesters linking arms on the beach in 2002. I've got a mate who works for MHL as a coastal engineer. 3) How much has Council spent on legal fees defending Land & Environment Court appeals related to seawalls since the 2016 storm? It's eroded locally at present, lots of rocks revealed on low tide but it's also end of winter. 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. It is worth remembering that this council, as Warringah, council, was twice dismissed for corruption and incompetence. Last Model Run: 15 Jan 11:00AM Local time (AEDT) 15 Jan 12:00AM GMT Data Status: OK. Run Age 9hrs. The GOR situation is far more complicated than Willi's well-intentioned advice makes out. The properties were bought in good faith, said one local who wished to remain anonymous, and the owners must feel an obligation for the authorities to protect them, but a seawall is last century thinking.. Absolutely spot on, Craig. The seawall is probably built over them. A "macabre" scene greeted surfers followinga mass kill of invertebrates. On the MP they blew the heads up and the erosion from Portsea front beach to the heads is crazy. Interesting to see if the slowed (design of) sand migration has had any knock-on effect for the likes of Tallebudgera- Burleigh and beyond. Cheers for the knowledge Craig. 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. Indeed. There's only a loss to be made for the purchases. It's been seven years since the last, but the event has been called on off for this Wednesday - Hawaiian time.
