“Unlike flash flooding, urban flooding can affect people regardless of whether or not they live in a designated floodplain. It’s not about the creeks rising. Rather, it’s about how the impermeable built environment prevents water from being absorbed into the ground. Rainfall on asphalt cannot sink into the soil, so it often ends up running onto properties and into basements nearby.
As part of our ongoing efforts to establish the term urban flooding, which is widely used in the United Kingdom and other parts of the world, we are working to make the definition more widely available online, such as on Wikipedia. We are also convening survivors of urban flooding to tell their stories at our series of Gross Gathering events around Chicago. The first Gross Gathering was held at CNT’s office this past June, and flood victims shared the emotional devastation and economic loss brought about by urban flooding.”
