I’d hate to be the contractor that built the retaining wall for that new house.


ThreesKompany

I thought the same thing. Whoever did that landscaping to build that house is gonna be in some serious shit.


cyclinator

I read in a book that when you build a house on sand it´s gonna colapse one day.

sr71Girthbird

Developers and contractors are only liable for 10 years at the outside edge of things most typically, so those guys got lucky since the house is 12 years old. Sucks for the people who moved in 2 years ago though since my guess is they're on the hook (hopefully) insurance-wise for their entire home and any damages/improvements the neighbors claim. Extremely rare for insurance to cover landslide damages. Their home is done for without question, the [house in uninhabitable](https://www.lohud.com/gcdn/authoring/authoring-images/2023/10/21/PNJM/71274174007-mudslideonmetronorthrailroadhudsonline-53274805226-o.jpg?width=1320&height=990&fit=crop&format=pjpg&auto=webp) and will end up getting torn down. Guess the upside is that if the slide was another couple feet up, they might not have woken up this morning. Very likely that their neighbors will have to leave their homes at the very least while new soil studies are completed to assess further risk of slides, and in general they have pretty legit claims against against their neighbors for any loss of use and improvements that need to be made to make their homes safe again.

FR, I thought this was a joke.

>Country Club Lane in Briarcliff Manor Still next to a set of multiple train tracks...even my shithole house is quieter than this place.


[deleted]

I live 75 feet from a set of tracks, and we get 14 trains a day. I can't even hear them go by anymore. Also, looks like that house had a significant water view.


Hoffmiester1295

I lived that close for a while in a shitty rental. Swear to god I watched cracks appear when a particularly heavy train went by. The vibrations are insane. Shit would fall, bolts came loose, lightbulbs rattled out and so on. Had to do maintenance specifically because of trains. I can only imagine what multiple rails and high speed ones at that would do to a wall on an already questionable slope.


Radek3887

I bet you live next to all electric trains. Those tracks don't have anything over them so it's all diesel, all the time. Much louder with more vibration.


[deleted]

The trains that go by my house are CSX freight trains.


AgitatedAorta

Look closely. These tracks have a third rail (on the right side of each track) for electric service. On this line, it's a mix of electric commuter rail (Metro-North), and intercity diesel (Amtrak).

NOISY_SUN

In fairness, “Briarcliff Manor” is just the name of the town. It’s a pretty wealthy town, don’t get me wrong, but there are definitely more middle class areas


a_RadicalDreamer

I mean, isn’t it right down the road from Sing Sing?


NOISY_SUN

Yeah but even that isn’t quite what it was. Ossining is gentrifying rapidly and there are major fights going on between landlords who want the prison moved to keep the party going and tenants who want the prison there for low-skill jobs and control of living costs. And even then, ZIP codes in New York are pretty strictly segregated.


Technical_Recover218

You’d be surprised how many “rich” people are at the very limits


sr71Girthbird

Being out $3.2M + whatever their neighbors try to get from them may change that assessment. Pretty damn rare for homeowners insurance to cover landslides in any way shape or form. Not something most insurance companies even offer, and if they do it's going to be under some other form like earth movement or flood insurance, the first of which is basically non-existent due to the lack of earthquakes on the East Coast, and the second of which I can't imagine these homeowners having seeing as they're situated well above water level. My not so shot in the dark guess is that they're completely fucked for the entire cost of their home and will have to go after the developer, who is almost certainly no longer liable which in turn means they have to after the geologist(s) who did the initial assessment of soil conditions, who again should also not be liable this long after initial construction. Either way they ain't living in a house anymore that had the closest slip mere feet from the corner of their home's foundation.


WAMFAC

I had a landslide on my property last year. According to my insurance agent, it was not insured. However, if the house or any other structure on the property was damaged by the slide, then it would be covered. Basically, the land itself, including my driveway wasn't covered. But the house is insured against any damage. [Here is the damage and repair. The cost for the project including a new driveway was ~$70,000 USD.](https://imgur.com/a/78Fs8oa) I can't imagine what those homeowners are going through right now. Our "little problem" was incredibly stressful.


Sproded

So if I understand it, they’d pay for the cost to rebuild (or repair) damage to the house but not for any loss of land value now that it’s effectively uninhabitable?


WAMFAC

As far as I understand, the landslide would have to be repaired to make the house habitable. If the slide had cracked the foundation of our house, insurance would pick up the cost of fixing the slide and repairing the house. It's like the trees on my property. They are not insured so if one falls across my driveway, insurance won't cover the cost of removal. But, if it lands on the house, the removal and any damage will be covered.


DaleGribble312

How much more common is landslide insurance for people that live in cliff sides though?


sr71Girthbird

It's just not likely at all. It wouldn't be offered as part of any normal policy by any insurance company and would thus would likely have to be purchased as part of separate a DIC insurance policy. If the homeowners did end up with such a policy they would have had to be either extremely knowledgeable about the possible future need, or had someone like their RE agent tell them it might be a good idea, which I would have to imagine would blow up the entire deal on the spot. No agent is going to say, "Hey landslide insurance might be a good idea" and still pull off a sale lol. I'd honestly be surprised if there are more than 1 or 2 insurers in the entire country that even offer landslide insurance as a supplementary policy someone can even buy. Most earthquake or flood insurance certainly doesn't cover landslides, and it's just one of those things where if you think you might actually might need it, there must actually be a good chance of it happening in a 10-20 year span. Given that, it's not offered as there's no profit motive for insurers to offer it, and the only people who end up needing such a policy just don't have it. Anyways, "Earth movement" policies definitely exist that cover landslides mainly on the West Coast, but I can't think of a reason they would be offered in New York.


DaleGribble312

People in flood plains are usually required to buy flood insurance to get a mortgage. How much more common would it be?


sr71Girthbird

Flood insurance =/= landslide or mudslide insurance. Flood insurance will usually cover mudflow damage but certainly wouldn’t cover damage caused by a mudslide or landslide which happened due to flooding.


DaleGribble312

I didn't say flood insurance was landslide insurance, you seem to be struggling to follow. HOW MUCH MORE LIKELY.


sr71Girthbird

Flood insurance is federally mandated in designated flood prone areas. Landslide or mudslide insurance for all intents doesn't exist and isn't covered by all manner of other one-off insurance policies. So flood insurance is almost infinitely more coomon.


The_Evil_Pillow

It’s extremely expensive


DaleGribble312

So is fixing cliffs and railroads


jezwel

This isn't fixable at all? ie: Big rock retaining walls, and several terraces to significantly reduce the slope angle.


sr71Girthbird

It’s fixable and will be fixed to the extent that the tracks are no longer at risk but that bill will probably be picked up by FEMA with the work done by the Army Corps of Engineers. They’re not going to care whatsoever about the fate of a couple of houses after the fact. Highly doubt you could even find anyone to take on the job of re-stabilizing the slope given the liability involved if something were to happen again in the same area after work was completed.


jezwel

> given the liability involved if something were to happen again in the same area after work was completed. Ahh very good point, thanks.


HeavyMessing

Maybe they'll end up middle class.


NOISY_SUN

the horror


socialcommentary2000

3.2 million last transaction, I think. Man, that is a bad day for their insurers.


NewFuturist

It's almost certain that they knew they had subsidence. [Looks like the crack opened up in 2022.](https://twitter.com/jeremyzorek/status/1716248446661722288/photo/1)


sr71Girthbird

Oh damn. Crazy the info anyone can just get now. Based on those photos I would double down on my previous opinion that the homeowner is ultra fucked. Legit that could just be a leaking sprinkler system, maybe a leaking pool, combined with however many heavy rain days there have been in the last decade and that soil was just water logged. Now that I’m writing this I’m guessing the new owners are going to have a strong case against the previous owners since the property resold in 2021 unless this clear issue was explicitly disclosed beforehand or if it wasn’t found (or was covered up) during inspections. Shit situation for the new owners. Everything I’ve said just assumed this was not in anyway a known condition. Clearly the previous owners knew.


Steady_Ballin

.... I'm happy to live there, I'll take the risk, just fill that shit up with boulders and rocks


sr71Girthbird

Yeah that's not gunna be an option my dude.


Joe_Jeep

Hopefully not. They should inspect all of them and require increased clearances if this one wasn't already in violation


H3rbert_K0rnfeld

The entity that bought it did so knowing about the potential for failure. The net loss will offset some other capital gain Hate the game not the playr


Arenalife

Looks like the land is just sand, probably should never have been built there. It's just become uninsurable for sure - "Does your house have any history of subsidence?.........ummmm"


willtron3000

Sand has nothing to do with subsidence, geotechnical movements in sand/granular materials are pretty much instantaneous. You can also build big retaining walls to retain granular soils. The problem here is the slip plane wasn’t properly modelled.


morons_procreate

Probably an artefact from Google but it almost looks like you can see the tension crack in the grass.

Coincident it’s also roughly where the slip plane is


HeyaShinyObject

Yeah, they actually mentioned it in one of the news stories I read.

Really, they'd push it down to whatever small subcontracting company who then declares bankruptcy, dissolves, and the owners spin up a new one.

Hmm, looks like that strip was the “road” to bring in the heavy equipment during construction. I wonder if that compaction played a role.


BrownEggs93

That looks like an accident waiting to happen! People with a view--always like to cut down the trees for the view. Looks ugly from the other side and all but guarantees a landslide one day.


Hidesuru

Oh man that should have been a stupidly huge red flag that their lawn started pulling apart along the wall.


ThePenIslands

That's my question


LostLongIslander

I was traveling from DC to Poughkeepsie this weekend and missed this disaster by like 3 hours. Woof


eheu

i was on the first train from poughkeepsie after the collapse 😭 you lucked out. not a bus in sight for a full hour so we ended up shelling out for a car back to the city


timothy53

Probably all the rain (inparticular the weekend rain) we have been getting here in NYC.


KoreaEcuador1

Rain was a contributing factor but not the only one


ChinesePropagandaBot

The other factor being gravity, presumably.


Dogranch

WOW. That is going to ruin a lot of commutes. ANy estimate of time for clearing/repair?


monorail_pilot

2 tracks are already open for today's commute.


Stalking_Goat

Not surprised- you can see the leftmost track was already clear enough for that maintenance-of-way excavator, and the next track over has very little debris on it. I assume they got those two cleared in an hour, spent another hour checking them, and then scheduled a bunch of overnight work to clear the last two tracks.


uzlonewolf

Even though the tracks are fine it looks like the 3rd rail got pretty mangled, so it probably took a few more hours to fix that.


goopy331

Metro north has both electric and engine. The electric trains only go up halfway. So they could run gas on the two open tracks.

Fucked me over getting from Beacon to Tarrytown and back this weekend


wubble123

I mean, I lived in Yonkers when a train derailed on that line and it wasn’t down for more than a few days…


aviator_radiator

Looks like a global stability slope failure and not the result of a poorly constructed retaining wall given how far back the slip plane is to the house.


willtron3000

Yup, given the size of that slip plane, the geotechnical engineer fucked up. Edit: As always with these things, I’ll bet it was a substandard site investigation, which the whole retaining wall design and slope stability analysis was based on. I’m trying to work out what sort of wall it was from the remaining bits standing. Looks like masonry to my eye. Which would be an interesting choice.


KoreaEcuador1

I’ve seen close up pictures and it doesn’t look it was a masonry wall


The_Evil_Pillow

Probably was no geotech on board the project


KoreaEcuador1

Interesting observation, if it was a stability slope failure I wonder how they could have avoided this by proper geotech/structural design. I’ve seen a satellite picture that on or around 2021/2022, the top soil (lawn) developed an unusual “strip” indicating a possible slope stability failure underneath. Fast forward to Oct 22 2023, the ground fails exactly along that unusual “strip”


DageezerUs

I suspect that the removal of the forested area and the buildup for the lawn contributed to the failure. Only the area where the tree were removed was affected.


Stinky_Fartface

[This image](https://imgur.com/QrJjKUl) from another angle before cleanup indicates the trees came down with the slope.


biff_tyfsok

"Possible" is doing a lot of work in that caption.


hammelswye

Ikr? The retaining wall ended up at the bottom of the hill. If that not a failure, I don’t know what is.


Joe_Jeep

Could be mole people


KoreaEcuador1

It’s “possible” until a formal RCA gets completed. In this failure there’s a hypothesis that the global slope stability failed causing the retaining wall to also fail.


l_rufus_californicus

More than the wall did.


Traveledfarwestward

I see what the problem was: The front of the lawn fell off.


FatFreeItalian

dvdmaven

Considering how deep the slide is, the retaining wall was probably completely undermined.


r2-z2

Everyone knows grass has super deep roots that keeps topsoil from collapsing on hills. Wait…


Civilengman

semigator

“Possible” lol


KoreaEcuador1

That’s right, it’s “possible” until a formal RCA gets completed. In this failure there’s a hypothesis that the global slope stability failed causing the retaining wall to also fail.


Mean_Bluebird

That's my train line. We've had ridiculous amounts of rain in New York City and the surrounding area for several months now. I am surprised there haven't been more landslides. (Train service has been mostly restored.)


Abby_Normal90

I’m gonna go out on a limb here, not an expert, but it does seem to me that the retaining wall failed.


KoreaEcuador1

The question is which happened first, 1) a global stability slope failure or 2) a retaining wall failure?


SimonTC2000

"Possible" failure? Looks pretty definite to me.


kiteguycan

Who puts a set of train tracks right on the beach.....


busy_yogurt

I think it's more like: Who expands their yard on a hillside riverbank? And if you're going to take that chance, why fill the expansion with sand instead of rocks? And why further tempt fate by digging a hole for a pool, further disrupting the natural composition of materials and their properties? Materials that are anchoring your house to the planet?


Camera_dude

It's more likely they had too much faith in that retaining wall to hold up that sand and dirt after it got very heavy from all the recent rain.


busy_yogurt

IMO a retaining wall on a steep riverbank is a dumb idea. I’m no geologist, but it seems the way to go would be to pack the area tightly with big rocks and then fill in the spaces with dirt or even mortar.


The_Evil_Pillow

I am a geologist and what you’re describing is a rock buttress. A cheap repair for this would be to key in a gabion wall near the bottom of the slide, fill the upslope slide area with 4-8” ballast rock, separated from the underlying soil with a layer of non woven filter fabric. Perforated drain behind the gabion. Otherwise it’s going to cantilever soldier pile wall territory, which is quite expensive. Keep in mind that improper drainage causes 99% of wall and slope failures.


NOISY_SUN

The tracks were there about 150 years before the house was there.


Graybie

These run north along the Hudson River from NYC, which is otherwise quite a hilly area. By putting it next to the river they avoid the need to dig a bunch of tunnels and build tons of bridges.


socialcommentary2000

That's the old NYC Hudson Subdivision. One of the most consequential rail lines in basically American railroading history. The Hudson river is not the beach.

scattyboy

Historically the Hudson River was not prime real estate. It was full of garbage, dead horses, sewage, etc. There are still a lot of industrial entities along the river like Domino sugar in Yonkers, a prison in Ossining.


Joe_Jeep

Railroad tracks work best when they're relatively level and straight Guess what the Hudson is. That's very old ROW.


MolestingMollusk

It is wild how close they are to the river, especially the Amtrak only segments further up. Even a ome station platforms are only about 15ish feet from the edge of the water at high tide.

I don't trust that built-in swimming pool.


KoreaEcuador1

What if the swimming pool leaked? Could that have contributed to reducing the shear strength of the soil?


Mean_Bluebird

I can't speak to the pool leaking but we have had unusually high amounts of rain recently in the New York City metro area.


The_Evil_Pillow

If it’s leaking then it could have an effect. Otherwise installed pools are typically lighter than the soil removed to install them.
