collaroy sea wall protest

A new wavepool development for the Sunshine Coast points to the future of pools in Australia. 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. 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?? I find the whole thing fascinating, I had guys from the council to my face tell me of a future with 52 day heatwaves & in the same breath tell me of being concerened about extreme cyclones & erosion. Other than buy the land and let nature take its course Im really interested to know if there are any other options - not brutal like this but that might be effective ? 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. @Tango Def landing size incorrect i reckon900mm min ? It would be the same as for any development adjacent to the cables where they make landfall. Until then the owners can continue to enjoy their delightful seashore experience. It also enshrines a process of community consultation before a council adopts any coastal programs. It's important to also recognise, the wall is entirely on private land. Bullshit. Good point, however wouldn't a potential buyback theoretically drive the price up? Both Brendan Donohoe and Angus Gordon, and other people Swellnet spoke to, admit to being blindsided by the construction. For example, during sunny conditions in Collaroy beach, constructive waves transport eroded sediments from cliffs and headlands to build up the beach. The exception of course is if youre a donor to the LNP then a $3M block of land can be sold for $30M!!! It is possible that this is part of the Silverback's Seachange pork barrel rollout. Im just saying its a difficult issue, beachwall terrible and if its sets a precedent huge chunks of the coast stuffed. Collaroy sea wall. The works to protect private homes is being 80% funded by private owners, with Council and the NSW Government contributing 10% each. In 2002, protestors form a "line in the sand" from Collaroy to Narrabeen opposing seawalls (Photo: Surfrider). And more recently there was a local magazine piece discussing future sea level rises and the Noosa beach rock wall not being able to contain that, plus the homes along the Sunshine Beach to Peregian Beach stretch being at future risk, and councils would be needing to address that. More than likely entombed in one of those tetrapod molds you mentioned above. "Environmental vandalism or gross negligence?". >>Really dumb idea. Market value is driven by what people are willing to pay for it. The option of do nothing seems to have passed but it can always be thrown in as a baseline. Good point, lilas, that explains the mystery of why aborigines didn't build their homes close to the ocean. 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. which is why the video is so interesting. Even though they are sure to meet codethey dont look to going by the pic. Make his name famous: Peter Horton. The obvious one is disaster relief which will be a given in the medium to long term for the repair of the wall and its impacts to adjacent beaches. 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. Not off topic JS, wouldn't be surprised if there is a hyperlink to that video in the sea wall approval document!. and the second last line of your article states- 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.] And find outwhy you'll soon hear a hell of a lot more about them. The GOR situation is far more complicated than Willi's well-intentioned advice makes out. they will use loop holes to ensure eligibility. The sooner we (as humans) acknowledge the nature of nature, and work with it instead of against it, the better for everybody. It may not happen in my lifetime [fingers-crosssed] but it's a real issue when thinking about your children who eventually inherit your home. 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. Have you done a study already? Nobody there is in a position to offer 2-3 times market value. Step 3: Calculate the number of pilings that will be required. This sets a very dangerous precedent for the rest of NSW. Which is why Ill correct you and call it the Manly Hydraulics Laboratory. Sorry to go hard on your story like that but I feel we need to keep the science at the forefront of all coastal engineering discussions. "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." However, the residents focused primarily on the protest against the sea wall while not suggesting any alternate solutions to solve the coastal erosion, and therefore, failing the 3rd criteria. Ray Collins eat your heart out.. Good find. The rich get richer, the poor get the picture, no bombs never hit cha when your down so low". 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. Well now we know who is responsible for this debacle. If anyone used it and saw the second DA let me know. The theory is that the waves break further offshore, soaking up wave energy that would otherwise erode the leeshore dune system during storms. From deep state secret spot to modern media darling, what lessons can we learn from Cape Solander's evolution? "Once this is up it'll be a momentum for others to do it too," said Orth. the Senior Environmental Officer" Northern Beaches NSW govt!! There are three main types of seawalls: vertical, curved, and mound. Although ill be constantly monitoring the situation and around at cathedral the beach profile has certainly been getting steeper. Stupid dumbfucks. Im presuming that sand delivery's from the lagoon will be an ongoing thing. They aint getting crushed. EDIT: Just to be clear, the issue of erosion has nothing to do with sea level rise, climate change, or buying the latest board. Lets do the modelling and begin building offshore wave traps and manmade surf-breaks. as my old mate hutch likes to say. Brendan Donohoe says the . 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. Yep pretty significant increase in the height. It would be possible to introduce a major sand nourishment program to move the shoreline seaward, says Gordon. 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.. 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. I will check with him and report back. I looked at the Bruun rule - i think it was roughly 10cm sea level rise = 1metre of beach vanishes? Climate projections will have some Australian surfers rejoicing, and others not so. Painful to see such a blunt object of a solution. My view is if it cannot be protected by environmentally sound methods then that is the owner's problem. It is a difficult and wicked problem. In the end it's all pretty simple though, as most beach erosion of consequence is caused by large/powerful waves. I am thinking that sad as it may be, we will never be able to turn back the clock and have a natural passive coastline of Sandhills and trees. I posted links to the relevant council pages in the previous story. 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". The Palm Beach artificial reef is now completed. Multiple reports have previously shown a better cost effective way to protect public infrastructure on that stretch. The beginnings of a huge $25 million concrete wall in Collaroy on Sydney's Northern Beaches. Much better to work out a solution where the public doesnt lose their beach as per collaroy, but councils/government do need to help landowners. We need to get all the data and expert opinions out in the open before decisions are made. As mentioned in an earlier post, I place the blame fair and square at coastal engineers who design and approve these ill-fated designs. 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. One thing about mankind. It shows how different combinations of coastal defences and wave and tide conditions affect overtopping and flood risk. Not to mention the many brutalist houses dotting its once beautiful headlands. In the early 2000s, Warringah Council (as it was then known, its since been amalgamated with Manly and Pittwater) spent $6 million dollars buying three properties. A seven-metre high wall erected to protect beachside mansions from being washed away has sparked debate among locals in a wealthy Sydney suburb. https://www.odt.co.nz/news/dunedin/tarzans-stormy-st-clair-skinny-dip. Was it some random guy off the street? development, carparks & roads behind the hind dunes leading to biketracks, walkways, supporting the community including Thanks Stu, didn't even know such a thing existed here. https://files.northernbeaches.nsw.gov.au/sites/default/files/collaroy-na Collaroy Stormwater Pipe Outlet 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. To my way of thinking, and with a working understanding of government process, the real issue is the approval process. On top of this they have places sand band grounds out perpendicular to the sandunes. The problem is one of vertical fiscal imbalance. Aside from high tides and Tsunamis, Im guessing most islands/atolls dont suffer much erosion when surrounded by reefs? Please enable it to continue. A much higher amplitude as well. Picture: Nearmap A subsequent image of Collaroy Beach from June 8, 2016. There's been significant coastal erosion (acute) along the GOR in recent years, though only a handful of places have experienced coastal recession (chronic). On Saturday November 27th hundreds of locals came down to Collaroy Beach / North Narrabeen Beach in grim weather conditions to protest the monstrous 7 meter . This can easily be achieved by creating offshore reefs that reduce the energy to a level the beach can cope with. It's actually quite simple to install and get going unlike a lot of open-source software. Surely going to get all crazy reverb and backwash stripping their sand more rapidly as well. Looks like the council are aware of the liability concerning the still submerged rocks. 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? I am not stock market savvy. 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. "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. 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. Im not trying to be a dick about it. Could be some good entertainment next time some serious swell hits. 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. A concrete seawall designed to stop coastal erosion is being built from Collaroy to South Narrabeen on Sydney's northern beaches. How to Build a Seawall: Step 1: Conduct a thorough examination of the surrounding area and environment. If you are referring to Vertical hard structures then that needs to be specified). Probably not council's fault then, happy to blame the owners! My guess is that their engineers took a different view of how to best manage the situation. Around 80 percent of the cost will be shouldered by the property owners themselves while the remaining 20 percent will be jointly funded by the Northern Beaches Council and the NSW government. 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. 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. 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. https://www.smh.com.au/property/news/coastal-properties-at-highest-clima https://www.abc.net.au/news/2022-01-17/will-climate-change-put-an-end-to Kala Grace In Dramatic Rescue While Competing In Backdoor Shootout, 'Corners Of The Earth: Kamchatka' Tour Dates, Watch: Hossegor Super Session January 6th, Australian Designer To Launch Crescent Head Hotel Amid Local Development Concerns, Dead Marine Life Washes Onto South Oz Beaches After Flooding, Watch: Ryan Callinan // Beneath A Pear Tree, Watch: Cronulla's Jarvis Earle Wins World Junior Title.
