Homes Underwater?

Bizzare thinking. This year, in England, planning permissions for over 5000 new homes, have been granted on flood plains (https://www.theguardian.com/society/2021/nov/22/more-than-5000-homes-in-england-approved-to-be-built-in-flood-zones). All the indications are that flooding is likely to become a more common and widespread event in areas of the UK. The builders claim they 'have no choice', if they are to tackle the housing shortage. One might suspect that they really mean they have no choice, if they want to keep the profits rolling in. Homes on the flood plains are likely to be difficult/impossible to insure. People who purchase these properties might well end up being bankrupted. There will still be a housing shortage.
