Thousands more homes could be at high risk of surface floods driven by climate change and urbanisation in the coming decades, government advisers have warned.
And there needs to be more focus on “nature-based” solutions such as roof gardens, green gullies, drainage ponds and rain gardens to tackle the problem. In addition, the unplanned spread of impermeable surfaces, such as the paving over of front gardens, reducing the ability of rainwater to seep away into the ground, could put a further 65,000 properties into high risk areas, it said.
Local authorities and water companies should work together to develop plans that deliver locally-agreed targets with funding devolved to local areas, the commission recommends. The £12 billion figure could be reduced by action taken under separate plans for £56 billion of spending to reduce combined sewer overflows, which tip sewage into rivers and the sea during heavy rain to prevent systems becoming overwhelmed, the commission suggested.
yep. How about not building roads or houses on floodplains and maintaining drainage?
