Analysis: A step to counter climate change increases in urban flooding --"sponge cities"

As climate change amplifies urban flooding, here's how communities can become 'sponge cities' "When it rains, it pours" once was a metaphor for bad things happening in clusters. Now it's becoming a statement of fact about rainfall in a changing climate. Franco Montalto Phys.org

...sponge cities—a comprehensive approach to urban flood mitigation that uses innovative landscape and drainage designs to reduce and slow down runoff, while allowing certain parts of the city to flood safely during extreme weather. Sponge city techniques differ from other stormwater management approaches because they are scaled to much larger storms and need to be applied across nearly all urban surfaces.

...some U.S. cities are beginning to take steps toward incorporation of sponge city concepts into their stormwater management plans, but most of these projects are still pilots. If this concept is to evolve into the new standard for urban design, city officials and developers will need to find ways to scale up and accelerate this work.
