Storm water management help control flooding in cities as "it includes providing areas of green space to help with runoff".
<u>Answer:</u> Option B
<u>Explanation:</u>
Green infrastructure can help in order to manage both localized and riverine floods by reducing the storm water runoff and protecting floodplains. Green infrastructure strategies reduce runoff in areas affected by localized flooding, preventing water from overflowing pipe connections and pooling in streets or basements.
Habits of green infrastructure that promote infiltration are like bioswales, permeable pavements and rain gardens. Such activities minimizes the volume of storm water flowing into streams and rivers by conserving floodplain's natural function and mitigating destruction to infrastructure and properties.
