The co-founder of Ksubiis to launch a '70s surf-inspired hotel on New South Wales' Mid North Coast. 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. For me, the value of these properties is in the negatives and at the very least, its a big fat round calamari. This is where I live. I wrote to Many Hydraulics Laboratory to ask for the details regarding the sea wall assessment they produced. I think the wall is actually a good warning of exactly what governments mean by "adaptation and mitigation"..expensive projects for the construction industry rather than sound ecological management. First and foremost they say It's for erosion control but as you've seen after 2011 they did pretty much sfa. The sheer number of cables there suggests to me that an offshore reef proposal would be unsuccesful. Has any one ever suggested an off shore reef, seems like a win-win or is the sea floor unsuitable? Completely agree that not all beach owners are cashed up pricks. Whe I checked the link today on the second one it went to the first DA for the sloping rock wall, not the second one for the vertical concrete wall. 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. Until then the owners can continue to enjoy their delightful seashore experience. 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. Craig - we are expecting you to be down there at High Tide 11pm tonight with your Torch and Box Brownie for some more pics, Nah wait 'til tomorrow mornings high. The very thing we live for one the beaches is full of concrete and man made fuck ups. 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). Imagine the carnage during the next ECL. as the article states coastal erosion has been known since the 20s in that area and has been studied meticulously ever since. nothings going to stop him on his daily dip. Can't wait to see the classic "Dick and Balls" painted on that big ugly fucker. I am working on a gipa application to try and find out what community consultation they did for the second DA. It's actually quite simple to install and get going unlike a lot of open-source software. It is all about the road. 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. @dawnperiscope BB has there been any attempt to take the process to the Land and Environment Court? Will this mean sand depletion north and a build up south? Highly unlikely! The NB has always excelled at extreme ugliness. What an absolute joke of a mess this has turned into. Shows what not to do, i mean it'd have some value in an inlet or lake subject to openings to the ocean in storm surge/high tides. Whether the NSW state government / local council want to backflip with a pike on their current failing seawall master plan is another thing. 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. It never went to a vote of councillors, where it would have been likely voted down . A much higher amplitude as well. Get access to long-range forecasts, hourly graphs and ad-free webcams. Agree 100%. After five years and four contests, the performance level at Kelly's Hot Tub hasn't evolved but instead gone the other way. There's no homes or businesses, or very few to speak of- doesn't come close to justifying the cost of the wall. Further to the north, sand that was built up in front of properties has been scoured away leaving an eight foot drop-off. 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. Lance Knight. The engineers would have likely argued against this for the reasons given above (and then some). Here's also the appendices and figures etc: https://files.northernbeaches.nsw.gov.au/sites/default/files/collaroy-na Yeah, cheers I've been through them as well. Btw when I say 4ft these waves 99.99% of the time are sloppy, they break for half a second and then dissapear and its an ugly wash for kms out to sea. 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. Angus Gordon, an engineer with fifty years experience in coastal engineering, assumed the same. I think this was done for the first DA, the sloping rock wall, rather than the vertical one that was actually built. Apparently this is just one part of the seawall. Establishment and set out of site survey control points. An awkward situation, but only for one of the parties, as the Woz suspends the current Longboard World Champ. Maybe "Collaroy" is the aboriginal word for "Stupid White people"? Their email is: [emailprotected]. Perfect future film location for backwash kook of the day. Posted the story from that link here. bit of a worry but, when you buy a nice piece of land by the ocean in high risk erosion zone..why do tax payers have to buy the property back,,,surely the owner knew the risks ? At what point are they a write-off? The 18-year-old scored a near-perfect 9.50 in the Final, held at Seaside Reef in Encinitas, California. Here's the full video with audio. Japan may be a perfect case study. 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. 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. I'd reckon the road, arterial services (electrical, sewerage, etc) and the houses all factors. Hi Lost, yes there is another option - see my 2 posts above. As a result, dried out sediments are carried by the wind towards the land. They must only exist on a dense (and expensive) schedule of maintenance, no doubt. You would never be allowed to build an incorrectly designed bridge, so why do these people get away with doing that at our beaches ? when roads and buildings are about to fall into the sea. EDIT: Just to be clear, the issue of erosion has nothing to do with sea level rise, climate change, or buying the latest board. If no acquisition or buyback is made, then good luck to the owners trying to sell these properties. Take a chill-pill mate, or possibly the whole packet as it appears you need them. The devil is in the detail and the more we understand the science behind it the better. Though with 80 properties at risk, and coastal real estate prices at a premium, they gave up on that approach in 2007. 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. With the benefit of ignorance, having not seen the actual plans, I'd be surprised if the foundations were able to fail easily as I'd expect they'd have been designed explicitly to avoid it. Collaroy homes along Pittwater Rd have been cordoned off today. For Sydney its not just beach suburbs. You said "They get paid to do what they are told to do" Were they told told to design a system that would not work for the purpose and only exacerbate the problem? You wouldn't accept that in a bridge from an engineer, so why accept it in anything else? A few years on when I visited I suggested a stroll along the cliffs at the estuary and they replied that its to dangerous now as theres been heaps of erosion for some reason. [Just like in Hawaii] Im presuming that sand delivery's from the lagoon will be an ongoing thing. They are multi millionaire asset owners. 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. Northern beaches residents have been worried about how their beloved beach would fare when large swells and high tides hit the controversial Collaroy seawall. The main issue is that the cables are protected in whatever is proposed. The angle of any hard hard structure relative to the wave direction is what really matters, so you can see why it's important to be very specific when talking about science/engineering. 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! Your browser has JavaScript disabled. 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? Dates announced for Spencer Frost and Guy Williment's film shot in Russia's far east. Its like stepping forty years back in time. It certainly doesn't make it the best decision though. check out the beach erosion in Apollo bay as well The root cause is building on the foredune. More often than not, the pollies retiire and are parachuted onto the boards of these companies and live out their lives having enriched themselves quite nicely. Who is going to want to inherit that when they exchange contracts? 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. 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. "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. Please include direct and indirect costs. 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? Council and State Government contribute 10% each. 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. Collaroy resident Tony Cagorski lost more than 10 metres of his yard during the weekend's wild weather, undermining the foundations of his home. It looks like Chernobyl. First completed by the French in 1735, the Pondicherry seawall reaches a height of 27 feet above sea level. However, theres an irony that could've beenliftedstraight out of a script for Utopia. 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. Not sure if that happened though. Not sure how they would fix them to the sand though. 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.] Wonder if he has been down there in the last 2 days to check on status of wall? 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). Existing market value must take into account that houses have erosion problems. For those who object to it, there is something hostile about Collaroy's multi-million-dollar sea wall. sea wall is perfect. So where public assets like roads are involved things get really sticky. Then there is the question of the parameters given to the designers of the second structure. A quick trip Todos Santos way during a belting nor'west swell. That's a form of speculation I believe. On top of this they have places sand band grounds out perpendicular to the sandunes. This issue is not exclusive to the NB or sea level rise or storm surge. Market value is driven by what people are willing to pay for it. 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. Stop wasting money and do something that will achieve the intended goals. It also enshrines a process of community consultation before a council adopts any coastal programs. In the Doc below, They advised to do more Numerical modeling [Physics simulations] to be sure of the walls effect. These walls stick straight up into the air like a fence made of steel or concrete. 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)". 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? This wicked problem is a result of intergenerational dumbness. You got to have demand/competition in order for a buyback to increase value of supply. My understanding is that the hard seawall was constructed with the specific intention to protect the private property behind the wall. For some it. The point i guess im coming to is, and i know an old couple whose property is very exposed to this issue, who have lived there since 1960's and are now in their 80's and likley won't see the impeding issues in their lifetime - but really they have done nothing wrong, bought an old shack in a place they love when no one lived up here, I wouldnt say there are a lot of people left like that but there are a few I know up here a version of that and the whole "screw those rich pricks" mantra is just divisive.
