According to the Federal Emergency Management Agency (FEMA), flooding is the most damaging natural hazard in the world, and most flood damage occurs in cities. As exemplified by Hurricane Harvey in 2017, this damage is projected to rapidly increase, both due to increasing extreme precipitation events and urban sprawl into marshes and floodplains—so it is critical that cities learn to adapt… Read more
