What does reducing runoff in urban areas contribute to overall?

Reducing runoff in urban areas significantly contributes to better management of stormwater. Urban environments often feature impervious surfaces, such as roads and buildings, which prevent water from soaking into the ground. This leads to increased runoff, which can overwhelm drainage systems and cause localized flooding, water pollution, and water quality issues.

By implementing strategies to reduce runoff, such as green infrastructure (like permeable pavements, green roofs, and rain gardens), cities can manage stormwater more effectively. This not only mitigates flooding risks but also improves water quality by allowing more water to infiltrate the ground, which helps recharge groundwater supplies and supports healthy ecosystems. Overall, better stormwater management contributes to more resilient urban environments and enhances community sustainability.
