collaroy sea wall protestcollaroy sea wall protest

Confirming that they were involved in the initial design only. The sheer number of cables there suggests to me that an offshore reef proposal would be unsuccesful. BB who is getting the sand which has gone from here? And the properties either side?? That's so shithouse I don't know where to start, Zen. A quick Google informs me that they are part of the State government, either Planning or Public Works, which was news to me because its mainly staffed by UNSW academics and is associated with the uni as a research centre. I am safely 140m above sea-level now so that should be safefor a while hahaha. 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. @dawnperiscope. Stick your comments up your arse fuckwit engineers dont approve shit like this they get paid to do what they are told direct your retarded comments at millionaire house owners and council you piece of shit. Turned this place into a concreters paradise. 30 years of volunteers doing Dunecare (eg. There's been significant coastal erosion (acute) along the GOR in recent years, though only a handful of places have experienced coastal recession (chronic). I liken it to a form of gambling. The best thing about it is that you can output actual 3d animations of the simulation so that EVERYONE can understand the results. 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! they might be right basis forecasts but beachfront owners bought in an area that didnt previously exhibit high erosion issues. Yep need to see front on pic Hi Craig, the short answer is I'm not sure as I have been out of NSW too long. I doubt there will be a demand for the effected given the inevitable. 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. I guess that the levees will give me a 100% guarantee that it'll never happen in my lifetime". Newiie Harbour was pumping. 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. as my old mate hutch likes to say. An "Engineer/s" designed this monstrosity and other "Engineers" approved it. It is a difficult and wicked problem. The UNSW Centre is called the Water Research Laboratory. That video represents a nightmare scenario, no beach, no waves and similar to Zen's story ie man made interference gone wrong. Bumper Farrell had the prime position. On top of this living around moruya last year the slow gently shaped dune leading into the beach was transformed for a straight 3m high drop off that you had to jump down by the end of all the ECLs around August. 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." When a hard structure is introduced to the equation we see an increase in reflective energy andturbulence, slowing the accretion of sandwhile also acceleratingerosion in storm conditions. Greed and stupidity rule in councils . Shit.That looks like they are preparing for an invasion. 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. Like I said at the start, IF he is an "expert coastal engineer" then we are in a much deeper hole than I imagined. Our services included: Pre-Work Detail Survey for existing surface levels at design chainages. (AO) Hows the Seawall holding up? good pics there willi, hadn't realised this. Step 3: Calculate the number of pilings that will be required. Super difficult problem, maybe councils could buy beachfronts then lease back the properties. They aint getting crushed. Now a 7 metre-high, concrete, vertical seawall has been built in front of private properties on Collaroy/Narrabeen beach. For those who object to it, there is something hostile about Collaroy's multi-million-dollar sea wall. Your browser has JavaScript disabled. Step 5: Construct the Seawall. Surf Breaks Inc. Coming to a beach near you ! Probably not council's fault then, happy to blame the owners! Apologies for misreading you. Bean counters at the local council know this too. Can't wait to see the classic "Dick and Balls" painted on that big ugly fucker. The recently constructed Collaroy seawall yesterday failed - or passed - its first real test, depending on which side of it you stand. The Northern Beaches took a massive hit by big surf and a king tide . As a result, dried out sediments are carried by the wind towards the land. 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 market knows the insurance companies know this. Seawalls form a defining line between sea and land. Yamashita (2020) "Living together with seawalls: Risks and reflexive modernization in Japan". Its like stepping forty years back in time. Sorry to sound pedantic but we should clarify exactly what we mean by "Hard Structures" as it's too general a term. If you look at the photo of the wall there appears to be a set of stairs built into the concrete for each property. You would never be allowed to build an incorrectly designed bridge, so why do these people get away with doing that at our beaches ? The protest was backed by the growing greens movement at the time and successfully pressured the then Warringah Council to knock back the protective walls. A few pics. There are plenty of other spots along the coast vulnerable to rising seas and more intense storms but Collaroy is one of the most difficult to address. Pretty incredible and frightening stuff. https://www.celeria.org/ 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? They must only exist on a dense (and expensive) schedule of maintenance, no doubt. My comment was maybe too obscure but was meant to be sarcastic. The legacy of that approach will be something future generations will have to live with.. https://www.linkedin.com/mwlite/in/peter-horton-coastal-engineer. Angus Gordon, an engineer with fifty years experience in coastal engineering, assumed the same. We all have valuable opinions, but they need to be separated from facts at all times, especially when it comes to Journalism. Beaches with hard structures can return, though it takes longer, and rocks and concrete in the wave zone also make for a dangerous combination. Thats just a done deal. 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. 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. I think we have already seen 19 cm of sea level rise on the east coast - and at least up here it hasnt translated to any significant/extended erosion issues. The politicians and land owners actions are an entirely separate discussion and I'm not entering into that minefield! Yep. Surely a planned retreat is the only way forward. Completely agree that not all beach owners are cashed up pricks. 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. 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. Might be time to lawyer up. As parts of the great ocean rd have began to crumble into the ocean. We need to get all the data and expert opinions out in the open before decisions are made. and who can afford to pay the rates and any rate increases due to sea wall construction costs, which will leave rate payers on low and middle incomes moving toward rather than away from poverty. I'd imagine brendan and surfrider will have that covered. Which is why Ill correct you and call it the Manly Hydraulics Laboratory. Agree 100%. 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? 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. For some it. Damaged houses and a collapsed swimming pool at Collaroy beach after waves of up to 8 metres hit the coast on June 6, 2016. Preparation of sea wall GPS file suitable for upload to GPS rover or machine guidance equipment. Theyre only a couple of hundred years away from Or boarding a jumbo jet to go for a surf and buy the latest board all things responsible for the needing of the wall in the first place. 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! 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. Further to the north, sand that was built up in front of properties has been scoured away leaving an eight foot drop-off. Cheers for the knowledge Craig. Amongst other things, it is illegal to "establish, maintain or use a spoil ground or other ocean disposal point (including dumping materials at sea)". Ha! Futile. I looked at the Bruun rule - i think it was roughly 10cm sea level rise = 1metre of beach vanishes? 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. You got to have demand/competition in order for a buyback to increase value of supply. 42 online submissions ALL supporting the wall but many seem to think it would be a sloping rock construction. 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? The Collaroy Beach coastline on May 6, 2016 before major storms swept the shoreline. Lindsay Fox is happy as a vegemite as he now has what he wanted all along, more real estate to land his helicopter on. https://www.dexpan.com/pages/how-to-use-dexpan-break-concrete-rocks-easily. Who could forget the MOLE building or the spoil from the North Head Sewage Works tipped over the cliff? The whole buy back argument being too expensive is a crock of shit. These impacts would have been explicitly tied to that particular design option by the engineers and other specialists involved. Thanks, Lilas, I agree with there being challenges inherent in generalising, but I'm going to resist the temptation to take our shared pedantry down the rabbit hole this time! These contracts to the construction companies are worth hundreds of millions of dollars. Sea level rise equation is based on the Bruun Rule to ascertain erosion in open coastal areas like Collaroy. Rock barrels at its best! 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. Zen interested how Japan just keeps dropping those big Tetrapods anywhere there is coastal erosionlost a lot of surf spots..how effective do you think they actually are against erosion? 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. Apparently this is just one part of the seawall. 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. Basically the awarding of contracts falls across a couple of ministries. Yeah nah. 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? For a couple of furlongs it was quite close to the ocean but nobody cared. It never went to a vote of councillors, where it would have been likely voted down . From their perspective building the wall before further erosion took place and moved closer to the road was another advantage as was disregarding the impact on the beach for a potentially more permanent solution. Who is going to want to inherit that when they exchange contracts? To add a bit of controversy, I've often wondered: Is Carties borderline just a novelty wave? 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. Unfortunately politics and money flow are not associated with longer term planning in Australia at present. If you want to witness how to do irreparable damage to a coastline, look no further than Japan. Will be ironic if they have to pull it down for not meeting code on the steps. Action: Casey Johnston to forward initial site visit details to Taskforce members, noting there will be a further site visit as the project progresses". To my way of thinking, and with a working understanding of government process, the real issue is the approval process. You shouldve known by 1990. It would have been a bargain 20-30 years ago to buy the properties and return the space to the public for the purpose of more effective less intrusive, natural and cheaper remediation efforts. Another week, another pumping day in the south-west of France. Your browser has JavaScript disabled. That 3-4x the height of the curved revetment? Vertical Seawalls Vertical seawalls are exactly what you think. Aside from high tides and Tsunamis, Im guessing most islands/atolls dont suffer much erosion when surrounded by reefs? That's appalling if it's the case, BB. This seawall will not only protect our homes but also Pittwater Rd, and the many communication and public services installed under it, from inevitable future storm events. Such a shame that it's not like California or other US states where the owner has no right to protect their land from erosion etc. https://eservices.northernbeaches.nsw.gov.au/ePlanning/live/Public/XC.Tr First red light! Lance Knight. It's like companies using buybacks in a crisis. It's important to also recognise, the wall is entirely on private land. Please enable it to continue. Most of these dunes have been heavily impacted by the La Nia easterlies over the last 2 years causing several car parks next to the beaches to be roped off. Was the carpark damaged by the 2016 storms and if so-to what extent? I also presume the view of the houses will be enhanced by the no trespassing signs in large red writing. they will use loop holes to ensure eligibility. 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. Edit: The estuary was in an area protected from the ocean and the cliffs only faced small wind chop and the tides. Death of Her Majesty Queen Elizabeth II. It has to be worth a look. I will check with him and report back. Sure, but wowee regarding that huge backwash and wave entering back into the surf zone. 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. Surely going to get all crazy reverb and backwash stripping their sand more rapidly as well. 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.". Thanks lilas. Unfortunately, what we see in Collaroy might become a norm to protect this lifestyle. I think they would be very happy with an ugly seawall. Willi, how would easterlies impact the Great Ocean Road coast? Inevitable as the ocean winning, is a painted "cock and balls" on that wall. Granted the Reality series and Aero are ludicrously expensive at the $2,000 barrier, but they're promising to push a more immersive, satisfying VR experience that delivers on incredible fidelity. How to Build a Seawall: Step 1: Conduct a thorough examination of the surrounding area and environment. In 1974I witnessed what cyclonic ocean power can do to ignorantly planned beach development 50 years on and a lot of sea miles under my belt. Google "End-wall effect erosion" and you'll find many papers/studies on this. "Update from Council on possible site visit to Northern Beaches: Casey Johnston advised a site visit to Narrabeen-Collaroy is being canvased for early December 2021 to allow review of their seawall in construction. Maintenance starts 2 months (?) 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? "community engagement", and my personal favourite "building resilience". 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. Even though they are sure to meet codethey dont look to going by the pic. From the last set of minutes from the Wamberal Seawall advisory Taskforce Nov 18 2021. PW road and any associated public infrastructure was used as a eligibility factor for public funding to protect the private properties. It's good to see some enlightened input from Brendan and Angus, both of whom have extensive experience in coastal management from planning and engineering backgrounds. Just like when the stock price of a company increases because of a speculated takeover bid. Such a shame. Kimura (2016) "When a seawall is visible: Infrastructure and obstruction in post-tsunami reconstruction in Japan" Scientists need to be able to communicate the results of simulations/tests in a way everyone gets, not just a bunch of numbers. Donohoe has presided over the Northern Beaches branch of the Surfrider Foundation for over twenty years, and hes currently livid with the council. The road is the public asset to be protected yes linked to their actions - but if it was really only just about PW road then surely a more cost effective way would have been to introduce less expensive and arguably more effective measures as I understand earlier reports have indicated including reveg and rock? the whole sea level/erosion issue is here now ..hmm any idea's solutions you have come across? The erosion at Collaroy/Narrabeen Beach is not particularly significant, unusual or surprising. 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.. 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. There's only a loss to be made for the purchases. Would be really good to see an article on the current state of affairs in the Coastal engineering world. In 2002, about 3000 people took to the beach to protest a planned sea wall, concerned it could destroy the beach. In the future, the problems may well be exacerbated by the above but they did not cause it "in the first place". Im presuming that sand delivery's from the lagoon will be an ongoing thing.
