Future Flooding

Might there be preventative measures planned over the next 30 years? It seems criminal to build knowing that the houses might flood, but if there is a dam or floodgates going in, it could make sense.

It isn’t the government which allows building, it’s the local planning authority. I had a developer client who wanted to build houses in an area with potential for flooding, planning permission was granted and he went ahead despite my warnings. The profit motive. That was just before I retired so I have no idea how easily the houses sold.

Isn't it likely to come up on searches when the houses are bought? I'm surprised that people can get mortgages on them.

The lenders only know as much as the solicitors tell them. Some solicitors are rather more diligent than others. And the planners would probably require some flood prevention measures to be taken, such as raising the ground level of the houses - might stop the house flooding but doesn’t stop the garden being ruined, possibly the car too.

The specifications for flood risks changed in 2022, they are now more stringent. I suspect the houses that are currently being built were given PP before 2022.
Some new developments have large ‘lake/ pond’ areas that presumably are to mitigate flooding by draining surface water.

DH has a client who is in a similar position to your friend.

Probably part of the SuDS, sustainable or an drainage system on newer housing sites J52.

Urban, not or an!

The Government are always pushing for easier planning permission have not mitigated against the risks when they could have done. I am related to someone who is heavily involved in presenting to Government the problems we are going to face with the rise of sea levels and has been for the last 15 years. Ministers nod their heads sagely and then carry on regardless. As my friend says, it isn't him who will have to worry because he will probably be long dead but the younger generations who will be living in properties that are just about to be washed away.

Residential development has been prohibited in my area for some time by the Environment Agency (for which read ‘the government’) because of the risk of pollution by sewage. Measures have to be taken by developers to prevent pollution before development is allowed.

Surface water flooding is of course another matter.

It’s very much up to developers looking to make a profit to ameliorate the effects of foul and surface water flooding and pollution, and the cost of necessary measures will of course be taken from the land price - which, rather than from the taxpayer, seems reasonable to me.

There has been a lot of building development on flood plains over recent years.
Not only does it mean houses etc may be liable to flooding in future, it also means that rainfall, overflowing rivers have nowhere for the water to ve absorbed.

These areas are not called flood plains for nothing - our ancestors were wiser than us!

Our area is being inundated with new development and the water companies say they can cope with it but the reality is that they can't. Our surrounding seas are being polluted on a regular basis and we are no longer able to swim safely. My daughter's house has flow back up into her toilet and bath whenever it rains and no-one will take responsibility for it. She is not alone. People on her housing estate are complaining about it all the time. We do need more housing, we just have to plan so much better.

There is an online map of the U.K. which tells you the areas likely to be affected by flooding due to Climate Change over the next 30 yrs or so.

This is as well as new builds but you can check online to see if a town or village you are wanting to buy in is at risk of flooding.

The flood plain near me has permission for 3,000 homes!
They have built probably half of this and have made big lake/ponds everywhere.

A whole lot of us will be at high risk of flood (or underwater) in 30 years - if nothing is done.

I should think it's just a standard area check - and you can check yourself. I'm near a river but, thankfully, a little way uphill from the risk area (for now):

These flood risks are worse scenario cases if temperatures should rise to the maximum predicted level by climate alarmists which is very uncertain. Should Hinckley Point nuclear reactor be built when according to the worse case climate maps it will be well under the sea in the next 50 years?

The climate alarmists are not really alarmists surely?

Aren't they just experts in their field pointing out (with modeling) what could happen?

There was a tsunami up the Bristol Channel and River Severn once before 🤔

According to Professor Simon Hallet’s research that seems to be correct.

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.

I think climate scientists look at a variety of scenarios including "worst case". I think they usually say whether it is "worst" or "best" or "on the current trajectory" etc.

I still don't think that makes them "alarmists".

What is alarming is the fact that the government is not going to mitigate against sea rise and flooding in so many areas.

The EA has no power to prevent building on flood plains - it can only advise which is generally ignored.

Those climate scientists who look at the worst possible outcomes are to my way of thinking climate alarmists. Not all climate scientists think that way.

Where my DD lives the builders have had to build SUDS ponds which are now teaming with wildlife and integrated open spaces into the development.

Tell that to the EA and other authorities responsible for climate change preparation. They are all preparing to mitigate as far as possible.

In point of fact the climate is warming far quicker than the worst case scenario a few years ago.

Climate deniers like Trump are frankly a pain in the ass.
