It was worse than the pictures when i drove by. And the other side of the roundabout is worse again. Is the relief work doing its job to be in that condition after a 12 hour period of heavy rainfall? What would it be like after a week of excessive rain? Do we say, sure lets find out or address it?

Doubt anyone would get flood insurance there now.

I would also have a severe concern about the dangers of the water and how accessible it is. It would be dangerous enough for adults. Lethal for kids.

Looking at the photos, the water levels would need to rise another 6 - 10ft before the house are effected. That's a reasonable indication the relief work is working.

If we're talking about guessing what might happen if this rain continued for a week, I don't know. Do we know if the current plans have already covered that type of weather?

It is visually worse to the naked eye than those pictures appear. That is from going and seeing it 2 hours after they were taken.

The issue is not "well it was a lot of rain in a short space of time so what do you expect?" The issue is, are the flood relief works fit for purpose? What happens if it was a status red? If it was yellow for 2/3 days or a week of standard rain follows todays rainfall? How far is it from capacity right now and at risk of over spilling? That's not being dramatic, it's a genuine question. For example, would another 20ml of rain in 24hrs cause an over spill?

They certainly appear to be fit for purpose so far. Some of the worst localised flooding we've seen in a good while and the new development appears to be pretty much unaffected.

As to how far from capacity, I couldn't tell you. It will be interesting to see if anything changes over the next few weeks.

If you look at the flood strip as a large bath with sides 8 - 10ft high, so far the base of the bath is barely covered. Assuming nothing happens to block under the new bridge, I'd expect wider flooding to occur upstream/downstream if anywhere.

http://www.meathchronicle.ie/news/roundup/articles/2017/11/22/4148788-flooding-across-the-county/

Last night's torrential rain saw serious flooding across the county, including at least one house in Trim and at the new Millerstown Estate in Kilcock.
It also caused nightmares for commuters with massive delays on the M3 because of flooding near Blancharstown and Dunboyne, due to the Tolka River bursting its banks.

It is believed a house in Cedar Grove, Trim has been flooded and a stream has burst its banks in Butterstream Manor flooding gardens and roads around the estate and threatening houses. Meath County Council had the fire brigade on site trying to combat the floods.
Ronan Moore of the Socialist Party said there was also flooding in Avondale and Eldergrove.

Meanwhile, flood waters are believed to be threatening houses at Millerstown, Kilcock and there has been flooding on the Rooske Road in Dunboyne, sparking fears of flooding in local housing estates.
The Clonee to Kilbride Road is also flooded.

In Navan there is severe flooding a the junction of Academy Street and the Inner Relief Road.

Mid-morning, the floods were not threatening the houses themselves. Whether the flood waters have risen significantly since then, I don't know

I am sure the waters will recede in time for the formal launch of the estate this weekend.

Don't suppose you have a wider shot (looks like that photo is cropped so guessing that you have a wider shot) so that I can compare with my photos from this morning?

Looks like heavy rain is hitting the area again (Dublin is about to get pretty torrential rain) but should clear in the next couple of hours

Graham · 22-11-2017 6:16pm

It really looks like the flood planning is going to be put to the test for the next few hours.

NedNew2 · 22-11-2017 6:29pm

Half a metre of flood water near that field now.

liam7831 · 22-11-2017 6:48pm

Wonder will it affect people's opinions on buying there ?

mirrorwall14 · 22-11-2017 6:50pm

As a parent it would certainly impact me, fine the houses might not flood but that’s a raging river not far from my house with zero barriers and when flooded it’s obviously gong to go beyond a fence even if they put one up

The drone footage on kilcock community network on fbk is worth a watch. If all the land is built on, around to Summerhill Rd, I think you will end up with a decent sized river from all the drainage.

sandra06 · 23-11-2017 3:58am

i was driving the rd from moyglare to kilcock about 4 pm today there was floods everywhere looking at the footage the rd ajoins the back of the new estate took a hour and half to drive about a mile ,,its crasy they got planning premisson to build on a flood plane ,,

Just to Give you all an update on where the Meath Planning Authority stands on this.

I rang them regarding Application number RA150205.

I said to them that planning permission was granted based on a flood risk assessment and flood mitigation works.

Then I told them that "a portion the site flooded yesterday. Why was this planning granted on a "known floodplain" etc etc. There are 152 houses to go up, fortunately none are occupied yet but it is very concerning early on. "

The reply was "It is entirely up to yourself if you buy a house in a place that is at risk of flooding" ... So they are not taking responsibility for the 152 unfortunate customers who will be buying houses based on the Meath Council granting permission to Build there.

Didn't the flood mitigation works perform as expected?

i.e. the part that was mean to get flooded, got flooded. The parts that weren't meant to get flooded, didn't.

We will wait and see if it floods. It held off last night. Weather Conditions are getting worse as time goes by.

Their attitude stinks. The whole thing does.

I hate to judge before all the facts are in, but it appears that the public officials who granted permission for this estate may not have had the interests of the population in mind when they made this decision.

Serious question, is it even possible to get insurance in this case? I suppose you can get house insurance that does not cover flooding? Will that satisfy a bank providing the loan?

Also, does anyone know how many yellow alerts Met Eireann issued in 2016 and 2017 for Kildare? I've had a quick look and annual numbers are hard to find. Can residents of this estate expect this to occur routinely?

Graham · 23-11-2017 11:13am

I genuinely don't see the issue.

A condition of the planning was flood mitigation.
The developer obviously implemented the flood mitigation measures.
The flood mitigation measures appear to have worked in fairly full-on real-life tests.

I'll try to explain.
1. Heavy rain yesterday brought water to within 100m of newly built houses.
2. You claim this is evidence that the flood mitigation worked.
3. However, it should be quite easy to establish (for example, if your full time job was working in a planning department) how much rainfall occurred over what duration yesterday and compare this to typical rainfall over the course of 12 months.
4. If the above data are known then we could determine if what occurred yesterday was an actual flood or merely heavy rain. Based on rainfall data from the past five years or so, we could also establish the extent to which the flood mitigation was tested.

highdef · 23-11-2017 11:28am

Ok, let's look at it this way - A large proportion of the houses in this estate are located on a flood plain and as a direct result, it will impact how they can insure their houses. I wonder if the developers/sellers of these houses will notify prospective purchasers of this fact before any contracts are signed?

I think that they MUST notify anyone of this if they are interested in buying a house. Personally, I would have researched it myself anyway and would have come to this conclusion but I have a habit of checking everything over. The majority of people do not.

Bristolscale7 · 23-11-2017 11:32am

Does anyone know if you can get a mortgage on a property for which flood insurance has been refused? Hypothetically.

2ndcoming · 23-11-2017 11:36am

Purely going by the fact that lots of areas I've seen flooded before were not flooded yesterday but this place was I would take that as a very bad sign.

When there actually is flooding this place will feel like Kevin Costner in Waterworld.

Maybe they could sponsor the Liffey Descent, could be a good target market?

The issue here is what event were the mitigation works designed to protect? It is difficult to establish what yesterdays rainfall event was in terms of AEP. I severely doubt it was a 1/100 yr event in terms of severity.

If a 1/100 yr event or even a 1/500 yr event occurs, where would the water levels reach then? Although these may sound relatively low probability events to happen there is a 1% chance of it happening every year if you live in a 1/100 yr flood plain. Even if it happened last year you have the exact same probability of it happening the following year. If you live in a 100yr flod zone for 50 years you have a 39% chance of the event happening.

In the case of this estate, I think it people should know what happens in a 1/5 and 1/10 event.

Correct, on the sacrificial strip.

Wasn't that the plan?

Last time we had flooding like yesterday was Aug 2008.

ixus · 23-11-2017 12:07pm

Graham, the river rose something like 10ft on a yellow rain warning of ~40ml rain in less than 12hrs. Not an orange or red, not a once in 100yr flooding event this is supposed to withstand.

It was a heavy deluge in a short period of time but by no means the worst we've had in the last 10yrs even. I recall not being able to get home from Dublin 4/5 years ago. I recall when they had to close schools and the University back in 2003 i think it was. You couldn't physically go anywhere in a car in Maynooth.

I get your logic, but your perspective or framing is wrong here I think.

I do remember that the flooding a few years ago quite vividly. We live in an area that's particularly effected every time it happens, it was touch and go whether we'd get home yesterday evening.

Aug 2008 was the last time I remember floods closing the M4 as they did yesterday.

None of that alters the fact the flood mitigation worked.

That's what I don't get. There's people calling out the council/developers for something that by all accounts appears to have gone to plan.

I'd absolutely understand the uproar if parts of Millerstown were discovered floating around the car park of NUIM this morning.

I'm not suggesting Millerstown is flood-proof, but by all accounts so far so good.
