Imagine how fun that'd be with your mates on a boog. Took the words out of my mouth. Please include direct and indirect costs. We do, but unfortunately we also have a pervasive mindset in surfing that everything should stay the same as it was back in the good old days. "Once this is up it'll be a momentum for others to do it too," said Orth. Owners, Council and 'engineersshame shame shame. This can easily be achieved by creating offshore reefs that reduce the energy to a level the beach can cope with. Man, that'd get old real quick, happy to pass. Was the carpark damaged by the 2016 storms and if so-to what extent? 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). Zen, it looks like an absolute disaster but Im guessing its not so much about coastal erosion but more about tsunami mitigation?? Mentioned in a previous article (linked below) - the region hosts submarine cables, so it's part of the Northern Sydney Protection Zone. Looks perfect for high tide backwash to spread up and down the beach. 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. https://www.9news.com.au/national/weather-nsw-sydney-collaroy-surfer-pul Sydney 'Living' Seawalls Caveat emptor..buyer beware. [happy to stand corrected on any of this] Surely going to get all crazy reverb and backwash stripping their sand more rapidly as well. 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. There is a common denominator here, "Coastal" engineers with a lack of knowledge and understanding of coastal processes. The 18-year-old scored a near-perfect 9.50 in the Final, held at Seaside Reef in Encinitas, California. 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. 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 More than a year after severe storms damaged property in Collaroy, construction of a long-awaited sea wall is underway. Beaches with hard structures can return, though it takes longer, and rocks and concrete in the wave zone also make for a dangerous combination. The process is cyclical, however short-sighted development upon the foredune, built during times of a wide beach profile, impedes the system. The people responsible for awarding the contracts get huge kickbacks. Cheers for the knowledge Craig. The root cause is building on the foredune. But several of those areas experiencing recession are linked to important infrastructure that the authorities want to protect - depending on were you are, the GOR also houses telecoms, sewerage and other infrastructure. The reef/sand nourishment are both mainly designed to widen and protect the public property, ie the beach, in front of the buried seawall. Market value is driven by what people are willing to pay for it. 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! 1. 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. If Surfrider and others haven't done it already, my view is that Swellnet, as a legitimate media organisation with a substantial subscriber and stakeholder base, could very reasonably write to both the NSW Coastal Council and Sydney Coastal Councils Group seeking advice about the adaptation options and why buy-back was not considered suitable for the site. What a mess. Hey guys I need to write an informative paper based on remedial measures used to protect infrastructure against erosion. July 28, 2021 - 7:04AM. It shows how different combinations of coastal defences and wave and tide conditions affect overtopping and flood risk. Mr Horton said current conditions have exposed a temporary rock bund that was put in place to protect the construction site, but it will be removed when works are complete. A weather-beaten cement plaque with the year 1952 is still visible along a section of the seawall. I dare say the neighbours are on notice too. Surf Breaks Inc. Coming to a beach near you ! 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 took the easy way, down towards the ocean and along on the back of the dune. Statements such as the two below can only be classified as opinion unless you link to references. 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. Is it designed to behave like a bottle-neck? If they fall into the sea so be it. It's like companies using buybacks in a crisis. But thats about it . Apparently this is just one part of the seawall. I just can't see HOW these monstrosities ever get approved, purely on an engineering level. Though not failsafe in extreme events, isnt it amazing how reefs and well-place gabions somehow protect small atolls in middle of the ocean for most of the time? They blend in quite nicely and have provided easier access to the breaks and so far been a success in the regions theyve put them so I fear theyll continue to put them in everywhere thinking they wont caus too much damage to beach profiles elsewhere. The exception of course is if youre a donor to the LNP then a $3M block of land can be sold for $30M!!! Bean counters at the local council know this too. So would you like to inform me as to WHO designed this monstrosity if it wasn't an Engineer? 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. The above video might be of interest to help understand the design of the wall. Collaroy Seawall Detailed Survey for construction of a new seawall in highly sensitive erosion zone. brutus Collaroy was not a typical situation. The Act was introduced by Rob Stokes, the NSW Minister for Planning and member for Pittwater. >> and the ocean will wash it all away again in the next big swell. what's the logic/law in having to buy back the properties ? OK this is the real one. I cannot see how can this be a feasible long-term strategy from the cost perspective. Though with 80 properties at risk, and coastal real estate prices at a premium, they gave up on that approach in 2007. Maybe "Collaroy" is the aboriginal word for "Stupid White people"? Apparently there was a buy back scheme that faltered in the early 1980's when the department of public works ran out of money. Posted the story from that link 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. 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. Construction of a seawall is underway to protect homes at Collaroy Beach. Basically the awarding of contracts falls across a couple of ministries. 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?!! Alas this would have meant some loss / damage to private property. Furthermore they have facilitated an increase of erosion to adjacent beaches. A quick trip Todos Santos way during a belting nor'west swell. https://nationalprecast.com.au/wp-content/uploads/2015/06/Collaroy-Beach 2020 Surfer keelhauled by Collaroy Stormwater Pipe {RIP} PW road and any associated public infrastructure was used as a eligibility factor for public funding to protect the private properties. The local community group has been protesting against a seawall for almost 30 years. Sorry Peter but we can't just take you on your word for it. The main issue is that the cables are protected in whatever is proposed. @yeti. Yamashita (2020) "Living together with seawalls: Risks and reflexive modernization in Japan". It's been seven years since the last, but the event has been called on off for this Wednesday - Hawaiian time. Yet for some reason the Collaroy/Narra stretch seems to get flogged not only by mother nature but by poor coastal management approaches time and again. Ignorant clown" This isn't a new issue, as has been mentioned in the article above, and the longer we ignore the elephant in the room the harder it will become to resolve. You wouldn't accept that in a bridge from an engineer, so why accept it in anything else? Just take the hit cost wise now and return the area to something close to its previous natural state. I get informed about a proposed bike lane two suburbs away, questions an aghast Donohoe, but I hear nothing about construction abutting a nearby public beach?, Gordon was equally puzzled: I guess people become frustrated with the bureaucratic process and find ways of not involving the public. In the future, the problems may well be exacerbated by the above but they did not cause it "in the first place". The DA for the Collaroy seawall was approved while the Northern Beaches Council was under administration. 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? Just like when the stock price of a company increases because of a speculated takeover bid. We all have valuable opinions, but they need to be separated from facts at all times, especially when it comes to Journalism. A band of knowledgable people have gotten together and are in discussions about it and coming up with arguments and alternatives against it. Could be the camera angle but. Please enable it to continue. 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! In 2002, about 3000 people took to the beach to protest a planned sea wall, concerned it could destroy the beach. We can mess things up in a colossal way, and then keep doing it repeatedly. Lance Knight. Would be really good to see an article on the current state of affairs in the Coastal engineering world. (This statement also doesn't specify what type of HARD structure. Rad demo john interesting as Craig said to see the changes in shock waves returning seaward. Rather than a natural ebb and flow of wave energy, a hard structure increases reflective energy and turbulence, making it difficult for sand to settle and accrete. Cheers. Get access to long-range forecasts, hourly graphs and ad-free webcams. Make his name famous: Peter Horton. 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. It has to be worth a look. Harmer and husband have been protesting for 14 years to stop surf barrier She led 2002 lobby against $12 million wall proposed by Warringah council A monster Sydney storm wiped out properties. It just doesn't make the engineering firms any money or contribute to gross state product under the current economic system. The co-founder of Ksubiis to launch a '70s surf-inspired hotel on New South Wales' Mid North Coast. Perhaps off topic in relation to the above story but thought this video was interesting in regards to how certain structures change the amount of erosion and inundation behind structures from wave/tidal run up. The facts stand as such, an Engineer/s designed this monstrosity and no amount of excuses can change that. They have access to and use a large suit of software modeling tools, but unfortinately a lot of them don't have outputs that non-scientists can get their head around [just numbers which are meaningless on the surface unless you understand what they represent.] 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. The beginnings of a huge $25 million concrete wall in Collaroy on Sydney's Northern Beaches. I have to disagree. Proven time and time and time again that sea walls do not work- period. Do you know how deep the bedrock is? The Collaroy Beach coastline on May 6, 2016 before major storms swept the shoreline. Could be some good entertainment next time some serious swell hits. Establishment and set out of site survey control points. 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. The sheer number of cables there suggests to me that an offshore reef proposal would be unsuccesful. 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. Initial reports claim Marcio Friere wasn't wearing an inflatable vest when he was held down in large waves. The only way now is to harness the power of coastal construction science and engineering. 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. "We have the Tools and imagination" The primary mechanism for coastal land acquisition in NSW has been the Coastal Lands Protection Scheme, but it wasn't designed for climate/erosion buy-backs. When deciding to spend rate payer dollars, on what metric do they use without using the big IF ? Really interesting [and sad] to see this story progress in real-time. The best thing about it is that you can output actual 3d animations of the simulation so that EVERYONE can understand the results. I've written about it before but the real reason here is money- it is massive pork-barreling on an unprecedented scale. The second DA is now here. It never went to a vote of councillors, where it would have been likely voted down . Ignorant clown. LGA's apply for state and federal funding on offer for range of purposes. 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. 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. We need to get all the data and expert opinions out in the open before decisions are made. Precarious! As the article states, in terms of erosion, vertical walls don't work and actually exacerbate the problem. Actually I do understand why the council doesn't research an alternative to a concrete wall, because it's easier to build a wall, something humans have been doing for thousands of years, we're good at it. I looked into this again yesterday. Adjacent a second wall constructed just to the north, the half finished revetment was torn to rubble with dangerous rebar, boulders and cement being washed into the surf zone. Taxpayers pay millions of dollars on a asset that will require '000s thousands if not millions of dollars in annual maintenance to protect the value of a tiny handful of multi-million dollar properties owned by multi-millionaires who thought nothing of buying a property directly on a beach for a solution that only kicks the can down or up the coastline for some one one else to deal with. The legacy of that approach will be something future generations will have to live with.. 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. That's crazy stuff. I wonder if they're intended as some kind of device to absorb/dissipate energy rather than as trafficable stairs? That ABC article is spot on when it comes to waterfront properties. Probably not council's fault then, happy to blame the owners! The most notable benefit of sea walls is that they provide excellent protection against coastal erosion and flooding. https://www.odt.co.nz/news/dunedin/tarzans-stormy-st-clair-skinny-dip. Thanks BB.
