filling deep land by a river next to a bridge
filling deep land by a river next to a bridge
i have to opportunity to buy at a low price a large plot of riverside land 36x80m along the busy national road 7 and just before a bridge. good commercial area with plenty of local restaurants 10 min drive to KC city center and an awesome view (Riverview on 2 sides main road to front and a restaurant to the other side). the problem is that it needs to be filled, a lot. the land level is 3 to 5 meter below road level and being next to a large river there is the possible issue of the land being eroded away during flood season unless i build some land containment system. i am quite well versed in construction but this sounds tricky, especially since the expenditure must not be too high to the point that it is not a good investment anymore. if i can cointain the land filling costs at 40.000usd i think the investment can still be very good since the asking price is low and they need cash fast. now there is just a flimsy stilts bamboo restaurant on the land, i could just offer a low price and if they accept it keep the land for later but i dont see the cost of filling the land going down anytime soon.
currently i estimate that i will need 3.000 to 3.500 truckloads of land (4cubic meters each) at 8usd each including delivery and laying it down, the cost of building a proper containment system along the 80m long side is still under evaluation.
i am open to suggestions (from what would you do with the land once filled or if you think it is too much trouble to any contact to a specialist in building a stable riverbank )
If you are curious i can post some photos.
thanks in advance.

If the riverbed is sand, hire a dredge and pump the sand onto the block. WAAAAAAY cheaper than trucked dirt...

very good point, will look into that. however wasn't sand dredging for private use made illegal a couple of years ago? is this something that you can organize?
Yes, it is, and in KC they will closely watch you since a few years ago someone dredged a bit too enthusiastically and some houses on the riverside collapsed due to this.jackrossi wrote:very good point, will look into that. however wasn't sand dredging for private use made illegal a couple of years ago? is this something that you can organize?
If you build a construction to protect your plot from erosion, you might want to talk to the neighbors to. Is the plot on the west- or eastbank of the Mekong? Due to the shape of the riverbed the eastern part suffers most erosion while the western bank gets some free sediment in general. I've seen pieces of unprotected land on the eastern bank lose well over 10M in a year, despite vegetation.
Behind the new Immigration Police building in Chhbar Ampoeu (Boeung Snuor) people pumping a lot of sand from the river so just go there and ask them if they can do it for your land.

^there is either a 20 or 30 metre stand off zone from the riverbank.But in practice you have the land right up to the water as no one else can get access .

Why would you ask them? The plot in question is about 200km away. Besides that, the north part of Chhba Ampoeu is about one of the worst cases of erosion anywhere near the city.dracula wrote:Behind the new Immigration Police building in Chhbar Ampoeu (Boeung Snuor) people pumping a lot of sand from the river so just go there and ask them if they can do it for your land.

Why fill with dirt? Could be cooler and easier to fill with water, you're next to a river. People spend $10,000s emptying it, why go backwards and fill it?
Yes, less use of land, but you could drive large columns and build durable stilt platforms while it's dry with all the money you save.
Just make sure you build up the retaining wall (maybe large stones and concrete) and fill with water and fish. Scraps from resto and guests to feed fish. Much cooler, too.
My two cents, what a waste to fill with earth ...

You have got a point,you could even take the level down by another 2 metres and sell the soil and then create a number of islands to build on and beautifully landscaped.TristranandIsolde wrote:Why fill with dirt?

The river is likely to destroy the whole project at any time. I've seen the way a lot of places shore up their bank with some piling and fill, I'm not too convinced they could take a flood though.

You'd never be able to adequately protect 80m length of riverbank for $40,000.
thanks all for the kind advice,
@ kchang:
the land is located on the khmoung river just 6 or 7 min after crossing kizuna it is the next main bridge. plenty of people are filling land and building various structures, just across the road in front of the land plot an hotel has been built 3 yeats ago but they didn't bother securing the land in any way and you can start to see the beginning of land erosion on the hotel riverside (albeit very mild). I believe they are less strict on dredging in that area.
@ tristandisolde:
i took that option in consideration as well as just building a low weight structure on concrete stilts, nice idea with the fishes below a restaurant but i would not open a restaurant over there, there are probably 50 big restaurants within 2 km on that road.
@ lucky: yes the main issue is to have a safe and stable plot structurally and legally.
@ jacked camry: a part of the land has already a massive concrete wall build for protect the bridge head from flooding yet you are right it is not simple to contain costs and ensuring safety. i can go above the 40k mark but it would not increse the land value to a possible khmer buyer proportionally.
i might let this opportunity pass between the sangkat being not sure about any of my questions, ( we went to ask questions such as: where the river boundaries start? or can i have the permissions to dredge sand fron the river?with a professional translator and the answer were mostly a puzzled face like a gecko on the wall when you just turn the light on and a lot of "maybe..., not sure..., i think so"... ) and the complications in construction makes it a bit too challenging.
i will post some photos a bit later.

A cofferdam would be half if not a third of that to build.Broken into small sections it should be workable for a small team.Or maybe not I haven't seen the land to make an estimate .Jacked Camry wrote:You'd never be able to adequately protect 80m length of riverbank for $40,000.
