Just curious, if you were looking at a property and it flooded last night would it be a deal breaker, or would it depend on how bad it was? The rain last night was unprecedented, so it is likely some places affected may never be affected again…
And this:
"*Residents of the Boyne Court apartment complex on Greenmount Avenue in Harolds Cross have been evacuated from their apartments by members of the Dublin Fire Brigade…Ground floor apartments were flooded by several feet of water and residents on the second and third floor have been unable to exit the building. " * rte.ie/news/2011/1025/weathe … esday.html
I presume the current owners insurance will repair the damage but I think I would have have reservations now if I was the buyer
Yes, I wouldn’t want the hassle. Even if it’s only likely to happen a couple of times every 100 years, that still means you could end up with at least one year where you have major structural issues to deal with post-flood.
Are there any good maps of high-risk areas? I came across this one but it’s not that easy to use floodmaps.ie/
I would never ever buy a house with even a small chance of flooding.
I would determine a small chance as being either
a) proximity to a river, lake, sea
and/or
b) any previous flooding in the area in the past (inc. decades ago)
Last night was a record for rainfall in a day in Dublin. If a place did not flood yesterday, odds are it won’t in the future. This should assist your search.
The whole where it did and where it didn’t flood is very odd.
All the neighbourhoods surrounding me on all sides flooded last night. Crumlin, Harolds Cross, Dolphins Barn, Richmond and Harrington Streets and Kilmainham all severely affected. And there I was, just off Donore Avenue, some feet beneath the level of the Royal Canal 500 metres way, looking out at an almost dry road. How does that work?
the drains we properly cleaned … thats what it is … if the council do their job properly 90% of the damage caused can be contained and not result in the carnage that was evident yesterday.
Royal canal has nothing to do with flooding
The source of the royal canal is in Pollardstown fen in Kildare. Flooding primarily as a result sewers/culverts unable to cope with
large scale rainfall events,
reduced infiltration as a result of development
and poor provision of storm storage in new developments.
Even odder so. The Council can’t seem to even manage to keep the pavements clean and free of wet and rotting fallen leaves, so its bizarre if they are diligently cleaning the drains around the immediate vicinity.
Grand Canal, The Royal Canal is the one near Mountjoy / Croke Park on DNS
I don’t think I’d take last night’s flooding as the be all and end all of likely flood damage. Best bet, buy on a hill with no trees with falling leaves to block drains
Indeed. Given that I am known to break into a lusty rendition of ‘The Auld Triangle’ when in my cups, I ought to be able to tell my Royal from my Grand Canals
I keep hearing this; but I’m not sure if it really fits this time around.
The Drains really aren’t that big, most of the time they don’t need to be, you don’t size them to meet the 1/100 year event, but the one that happens regularly.
Look out your window during a severe rain shower, imagine all the water falling in just your line of sight going into a single pipe maybe 18" in diameter. It doesn’t take a significant increase in rain intensity before there just isn’t going to be enough pipe to get the water away faster than its hitting the ground. People forget that water isn’t compressible, so once the pipe is full, it can only enter the pipe at the same rate it exits at the far end, if the canal/river/storm drain is full, then no more water can enter the drain. People see water not entering a drain & assume its blocked, it may be, or it may just be full of water already, with no-where to go.
This is the scenario where all these culverted streams start percolating back up & causing flooding. The only solution is to do what they do elsewhere, & break down walls & let certain low lying areas flood. But of course we built on all those spots, didn’t we ?
