Future Flooding

I am helping someone relocate and he has just had a house report on the property he was hoping to buy. It said that within the next 30 years that his house will be at high risk of flood due to climate warming. Now, he can walk away with just the cost of solicitors fees (for the second time) but what struck me is that there is a whole load of building going on at the same or lower level than his prospective house. A huge estate is 3/4's of the way through being built which includes an Old People's home along with masses of family housing all to purchase. How can the Government let this happen? It is one thing to find out later floods might be a problem but to knowingly build is disgusting.

WWM2 this is not about climate deniers but about the extent to which climate change will affect us. Climate is not warming far quicker than the worst case scenario.

In what way do you think the scientists are wrong? I’d be interested in actual examples of where you think unnecessary action has been taken.

Frankly as far as flooding is concerned in our locality, £25 million was spent on new flood defence because of the expected rise in sea levels. That was completed 2 years ago. It is already clear that it will be insufficient.
Climate patterns and gyres are changing dramatically, causing sea ice melt, which will in turn aggravate an already disastrous scenario.

The house reporter is just covering their backs by saying that high rainfall might flood your property, if the house is on higher ground than surrounding properties and not close to a river you are highly unlikely to be flooded.
Unless your driveway slopes towards the house you shouldn’t be at risk

Sea ice melt will make no difference to the volume of sea water. It is land ice melt such as glaciers and the sea expanding as it warms that will increase the amount of sea water. Also there is the impact of land sinking which is happening in some parts of the US for example due to mineral extraction. Then there is the effect of weather conditions such as El Niño and La Niña. It is therefore incredibly difficult to predict where exactly sea rise will occur round the world and by how much. It will not be uniform. Computer models are predictions and are what could happen taking the maximum projections. We keep seeing the time date for the flooding of the South West back as it does not happen as predicted.

If the drive slopes towards the house, you could put a narrow drain along the front to take away the surface rainwater.

Of course, it would make no difference if there was a deluge or flood water coming up through the drains!

The house is at the bottom of the hill and the water table is quite high in the area. It is also below sea level and on the coast. The new builds are in a similar area within a mile of the property my friend was thinking of buying.

Below sea level, no thanks

Which is fine until storm debris blocks the drain, we had a major flood about 20 yrs ago it rained for 24 hours and recorded 6 inches of rain. This is UK midlands not overseas, incidentally the UK record is 10 inches in 1 day

NotSpaghetti, climate alarmists are those who look at worse case scenarios but if you read what they say they admit to that. If temperatures rise to the highest levels we could or might see significant flooding, not that we will and not that temperatures will reach that level. It is not definite by any means that we will reach those extremes.

Why have thousands of emperor penguins died in Antartica?
Because the sea ice melted before they had grown their adult feathers so they drowned.

The sea ice melting in Antarctica is not necessarily indicative of global warming. Walt Meier a sea ice scientist with the National Snow and Ice Data Center says “It is hard to say if this is a real shift and response to warming or just a temporal multi-year variation.” The press had to sensationalise it, however. Sea ice thickened on one side of Antarctic and thinned on the other. There are so many variables affecting this which is why the trend needs to be seen to continue before we can be certain.

It's quite clear from the Sunak/Give announcement that developers are being given carte blanche to build wherever they want regardless of pollution. Houses are seen as more important to gathering votes than pollution. The shortage of housing is such that people will buy them whether or not they are on a flood plain.

DH keeps our drain across the front of the house free from debris regularly.

It's wide and narrow but the grid unscrews so leaves etc can be cleared. We get a lot of leaves (not many are ours).

Storm debris would be unavoidable but the drain helps if we have heavy rain.

I've noticed that the Council don't come round very often now to clear out the drains either.

It's like this one:

Callistemon21 People have them here (a requirement for 'drainage' of driveways) and they're supposed to let water run through to the ground - not being connected to any drains. On our solid London clay they are absolutely useless!

My back garden slopes towards the house (and back of garage) so, when we have a deluge, drains further uphill can't cope. So many paved gardens and blocked drains mean it all comes my way, under the house and through the garage, far more frequently these days. The dreadful smell of stagnant water wafts through until it dries out again.
