When it rains, it pours. And climate change means it’s been raining more than ever.
Global cities, built in dryer times, aren’t prepared to handle the flooding caused by increased rainfall. Where there was once grass and soil to soak up water, there’s now impenetrable cement. (Something about paving paradise to put up a parking lot.)
To prepare for soggier days ahead…
- Permeable surfaces, such as concrete bricks separated by crushed stone
- Rain gardens, which can divert and collect excess rainwater
- Vegetated swales, AKA plant-filled ditches that soak up runoff water
But water isn’t always bad
As storms become more frequent and severe, so will droughts — so the ability to collect groundwater for drinking, cooking, and cleaning will be invaluable.
In case Mother Earth didn’t have enough problems, sea levels are rising, making spongy infrastructure even more important for coastal cities.
