Absolutely agree. To keep allowing development on Known flood plains is insanity.
Also the style of building needs to change to take into consideration the rising sea levels and increased risk of flooding.
New houses should be built raised a few metres from, ground level. There are several ways this can be achieved.
Its high time governments and developers got their heads together to find solutions.
Another problem that needs addressing is deforestation that has taken place in the past. Also the removal of the ancient hedgerows. These are just a couple of mistakes that were made in the past that have made the risk of flooding much worse while at the same time destroying wildlife habitats. The modern farming methods are inefficient and use far more land that is actually needed to feed the population while at the same creating problems that are very hard to overcome.
