Green infrastructure can mitigate stormwater flooding, which is responsible for about 25% of America’s annual $1 billion in flood damage.
(2014) Published by the US EPA. Brochure highlighting multiple benefits of green infrastructure in reducing storm damage to communities. Approximately 25% of the $1 billion in annual flood damages in the U.S. can be linked to stormwater. Green infrastructure can increase urban resiliency by helping to manage localized flooding, build resilience to drought, protect the coast, use less energy managing water, reduce urban heat island effect, and lower building energy use.
Green infrastructure uses vegetation, soils, and natural processes to manage water and create healthier urban environments. Green infrastructure can range in scale from site design approaches such as raingardens and green roofs to regional planning approaches such as conservation of large tracts of open land. In conjunction with gray infrastructure, interconnected networks of green infrastructure can enhance community resiliency by increasing water supplies, reducing flooding, combatting urban heat island effect, and improving water quality.
