What an absolute joke of a mess this has turned into. On the release of his latest edit, R-Cal chats to Swellnet about love and other acrobatics. And the properties either side?? There is a significant risk that, as Craig suggested, end wall erosion will simply move the problem and lead to calls for extending the wall. 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? Just wondering if the stairs built into the wall are private property? Turned this place into a concreters paradise. Not sure why coastal ginger beers (engineeers) assigned by local councils just keep getting it wrong, but it would be fascinating to go through the meetings minutes of how these get passed, and the deceptive and misguided arguments that must be being put forward. "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." I recently moved house [Northern-Rivers nsw] and seal-level rise was a very serious consideration of mine. 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. @yeti. 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. Is there a sea wall at Collaroy? It's corrupt to the eyeballs and the only winners are the crooked pollies and the dodgy construction companies while the once beautiful Japanese coastline is lost forever. In the Doc below, They advised to do more Numerical modeling [Physics simulations] to be sure of the walls effect. 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. A much higher amplitude as well. 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. If you're looking to protect your property from flooding with erosion control in McHenry, IL and the larger Chicagoland area, give Seawalls Unlimited a call at (815) 331-8830. Collaroy Seawall Detailed Survey for construction of a new seawall in highly sensitive erosion zone. 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. Now a 7 metre-high, concrete, vertical seawall has been built in front of private properties on Collaroy/Narrabeen beach. Hence, they are of no market value to me. other than just the width of beaches increasing, has anyone actually seen a full dune rebuilt. Any example around the world that have worked with out wrecking a beach but holding back erosion in built up areas ? Highly unlikely! Sure, but wowee regarding that huge backwash and wave entering back into the surf zone. Soon It Will Be Filled With Concrete.'. An "Engineer/s" designed this monstrosity and other "Engineers" approved it. 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. 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. "We haven't had a flood here for 20 years you say. As mentioned in an earlier post, I place the blame fair and square at coastal engineers who design and approve these ill-fated designs. It will still be a bargain now compared to 60 years from now if they do the same. https://www.odt.co.nz/news/dunedin/tarzans-stormy-st-clair-skinny-dip. Thanks BB. The people responsible for awarding the contracts get huge kickbacks. Sorry to sound pedantic but we should clarify exactly what we mean by "Hard Structures" as it's too general a term. 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. The reef/sand nourishment are both mainly designed to widen and protect the public property, ie the beach, in front of the buried seawall. They needed see this, but still probably wouldnt t have believed it. Lance Knight. Caveat emptor..buyer beware. 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. So would you like to inform me as to WHO designed this monstrosity if it wasn't an Engineer? My NSW water buddy says MHL are coyboys. 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. Preparation of sea wall GPS file suitable for upload to GPS rover or machine guidance equipment. 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. 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. A new wavepool development for the Sunshine Coast points to the future of pools in Australia. 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. Craig Brokensha on the Sunshine Coast there is a similar 'future' proposal for a rock wall between Alexandra Headlands and Maroochydore beaches. 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. I'm a huge tree-hugger but they will not stop powerfull ocean waves. 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. that concrete is a lovely blank canvas for some choice words. 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. They have just set a precedent for the whole east coast of poor me multi millionaire landowners to set up squeaky wheel collectives. The theory is that the waves break further offshore, soaking up wave energy that would otherwise erode the leeshore dune system during storms. 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). Sure if youve bought the last 5 years ignorance cant be an excuse, but theres nothing wrong with wanting to live on the beach. 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. Will try and find out. Looking at that DA via Stu's link, it must have taken a considerable, possibly illegal, effort to keep that out of the hands of those community members with a long record of interest in the matter. This would be a better solution, I think. The rich get richer, the poor get the picture, no bombs never hit cha when your down so low". Newiie Harbour was pumping. "We have the Tools and imagination" Here Willi. "community engagement", and my personal favourite "building resilience". Protesters linking arms on the beach in 2002. 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.. But thats about it . It is a difficult and wicked problem. Yep totally agree. Sea level rise equation is based on the Bruun Rule to ascertain erosion in open coastal areas like Collaroy. 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. The contractor is required to remove this temporary working platform and bund at the completion of the works, sieve the sand and remove all debris, and return the beach to its former state.. 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 . This is very different to Collaroy. 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. With expected sea level rises obviosly making those matters worse - however there is some irony in the fact Gina Reinheart whose carbon footprint is horrendous, just bought the most exposed land in sunshine beach to these very issues - but im also stressed people like her etc will want to build sea walls down the track. Im presuming that sand delivery's from the lagoon will be an ongoing thing. This will give all all a better insight into what's going on with these projects. Alas this would have meant some loss / damage to private property. The problem is one of vertical fiscal imbalance. https://www.planning.nsw.gov.au/Policy-and-Legislation/Coastal-and-marin "The scheme operates along the entire NSW coastal zone except for the Greater Sydney metropolitan area, identified as between Broken Bay (Central Coast) and the Minnamurra River (south of Shellharbour).". Pipeline specialist injured while duckdiving in heavy waves. 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. I will try and find some pics of my area. >> and the ocean will wash it all away again in the next big swell. Holds more water and replenish the beach? The whole buy back argument being too expensive is a crock of shit. As parts of the great ocean rd have began to crumble into the ocean. I just can't see HOW these monstrosities ever get approved, purely on an engineering level. 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. We all know there is significant increases in sea level rise..are we setting a precedent that if your coastal property succumbs to coastal erosion, you should be financially compensated? Climate projections will have some Australian surfers rejoicing, and others not so. I have limited state / lga experience but my perception is this broader thinking can get lost in short term self interest (putting it politely) as touched on by BB and others. It's eroded locally at present, lots of rocks revealed on low tide but it's also end of winter. Hi Craig, the short answer is I'm not sure as I have been out of NSW too long. Futile. Kook survives a brutal seawall bashin' well almost! No fuckers complained about the rebar reef. which is why the video is so interesting. The fact that an engineer/s designed this crazy-ass wall is the concern I raised. 2 metre swell at 13 seconds combining with a 1.8 metre high tide at nearly 9am should provide some good viewing this morning. Agree 100%. The engineers would have likely argued against this for the reasons given above (and then some). Lake that has been going on for the last 20 years. Seawall construction isnt mentioned. Links relating to the City of Sydney, and NSW in general - please read our rules before Their email is: [emailprotected]. Northern beaches residents have been worried about how their beloved beach would fare when large swells and high tides hit the controversial Collaroy seawall. At what point are they a write-off? Spot on. Joint Venture adopts new name, Te Puna Aonui. I do however feel there needs to be more separation regarding fact and opinion in your article. As you know we have the Great Ocean Road down here , which was a huge Tourist attraction ( before Covid.) Section 2.4 Item 4 - classic stuff. 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. Surely, private properties can be protected but public amenities will require huge ongoing costs to keep up with the public requirement (sand nourishment is the first thing that comes to mind). As a result, if the sea erodes the shoreline (and the tidal level moves inland) it encroaches upon land once part of someone's private land title. Stupid dumbfucks. Check this out. 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. The houses up the dune with no apparent erosion would be an apple compared to these lemons (for now). Unlike other approaches like soft beach nourishment, they offer a long term solution to shoreline erosion. "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. This is an example of the walls theyve been placing. Who is going to want to inherit that when they exchange contracts? And since there's been no budget allocated for future buy backs. 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. (As we all know, unfortunately, money/wealth/property seems to be many people's priority, and corrupt opportunists step in to "help" with that). I looked into this again yesterday. 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. 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. Great stuff. I suspect the engineering report will say thatif we ever get to see it. That's assuming the properties are still worth something to the market. Super difficult problem, maybe councils could buy beachfronts then lease back the properties. Certain death. The politicians and land owners actions are an entirely separate discussion and I'm not entering into that minefield! Given Council has already completed protection works on public land, and there's been a lot of talk about the owners' seawall, understanding all the facts is important. It didn't last long and within 12 hours the sand that was built up against the near finished first wall was 2/3rds washed away. Please enable it to continue. This wicked problem is a result of intergenerational dumbness. The seawall is probably built over them. I will check with him and report back. and I live 8 hours away. Our timber guide wall formwork is not only reusable and 100% recyclable, it also prevents dangerous polystyrene fragments from entering the ecosystem. But, they just persist time and time again.

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. However, the bean counters and quantity surveyors were extremely difficult for obvious reasons. Yes, blowie, I've yet to see anyone our age advocating for a soft solution. Get access to long-range forecasts, hourly graphs and ad-free webcams. Take the houses away eventually they would be building a wall to protect that road that you whinging moles drive around on for 20min checking it. 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? I doubt there will be a demand for the effected given the inevitable. A northeast swell generated by ex-TC Seth off Queensland,. Scientists need to be able to communicate the results of simulations/tests in a way everyone gets, not just a bunch of numbers. RAW footage from this week's extra-large swell at Peahi.

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. Making it deeper? 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. Your browser has JavaScript disabled. That 3-4x the height of the curved revetment? Tetrapods work but don't protect the adjacent beach very well unless there are multiple groynes. 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. 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. did depend a lot on steepness of the beach etc. (This statement also doesn't specify what type of HARD structure. 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. Unfortunately, what we see in Collaroy might become a norm to protect this lifestyle. Good point, lilas, that explains the mystery of why aborigines didn't build their homes close to the ocean. https://www.celeria.org/ Yes it is. My parents in NZ were excited when they took out bloodymangroves at the mouth of the estuary where they lived. 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. Last Wave inalways team up with surf buddies to safely exit yer local Seachange Monstrosity. 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. I asked a mate who works at MHL this exact question. buzzwords include "Improved recreational access. " I like the cut of your pedantic job, there Lilas. The public should not suffer loss of amenity or pay the costs to protect it. 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 have the mhl report but cannot find the link again. The Gold Coast has undoubtedly the most at risk coastline in Australia. 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. 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. Collaroy seawall project | Protection from coastal erosion Watch on Location: Collaroy NSW Our specialist staff were engaged by the Northern Beaches Council to construct the 250m rock revetment seawall in front of the Collaroy Beach carpark. Maybe "Collaroy" is the aboriginal word for "Stupid White people"? But unlike a rock revetment at Stockton, which gradually collapses into the beach, Collaroy's sheer concrete wall relies on deep foundations to stabilise it. 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. . This sets a very dangerous precedent for the rest of NSW. Structures appeared. 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). Bumper Farrell had the prime position. A few pics. Are the exposed quarried rocks part of the construction/ foundation or are they from pre existing efforts. How was Collaroy Beach made? 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. Our timber guide wall formwork is not only reusable and 100% recyclable, it also prevents dangerous polystyrene fragments from entering the ecosystem. Please include direct and indirect costs. The above video might be of interest to help understand the design of the wall. Its an issue the whole coastline, councils desperate to get what is a liability off their books and some homeowners, beachfront, genuinely caught out by it. 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. The activism of Tom Kirsop is legendary and in December 2019 Northern Beaches Council honoured him with a park at Narrabeen called Surfrider Gardens. I was watching the houses on the cliffs at Bilgola the other day. The project is part of the 1.3-km seawall proposed from South Narrabeen to Collaroy to protect both private and public assets in the suburb. 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?!! Planning Minister Rob Stokes told the Telegraph there was a recent plan to build a sea wall in Collaroy at the scene of the devastation but the owners would not agree on making a contribution, so it never happened. It is worth remembering that this council, as Warringah, council, was twice dismissed for corruption and incompetence. 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. Although ill be constantly monitoring the situation and around at cathedral the beach profile has certainly been getting steeper. 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. I think this was done for the first DA, the sloping rock wall, rather than the vertical one that was actually built. In the end it's all pretty simple though, as most beach erosion of consequence is caused by large/powerful waves. development, carparks & roads behind the hind dunes leading to biketracks, walkways, supporting the community including https://www.facebook.com/watch/?v=144437777895204. The thing is, the existing site was fine except a motorway was about to be built straight through it. https://www.9news.com.au/national/weather-nsw-sydney-collaroy-surfer-pul Sydney 'Living' Seawalls If the houses go, the road goes shortly after. 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. In 2017, Gold Coast City Council funded, in conjunction with threatened property owners, an artificial reef offshore from Palm Beach. Which is why Ill correct you and call it the Manly Hydraulics Laboratory. Counters and quantity surveyors were extremely difficult for obvious reasons better insight what.
