Rotterdam's mayor, Ahmed Aboutaleb has vowed to to make Rotterdam the most sustainable port city in the world. Part of this project is to build floating urban districts with 13,000 climate-proof floating homes in by 2040 -- of which around 1,200 would be built on top of the water, reports CNN.
To combat the effects of climate change induced high precipitation, water plazas are being built that serve as the perfect solution to holding excess water and take the pressure off the sewerage system. The video linked to the story shows the already existing solution of storing excess water under ground.
