Storm drains play a crucial role in urban planning and infrastructure by helping to manage stormwater effectively. In urban areas, where impermeable surfaces such as asphalt and concrete dominate, natural water absorption into the ground is significantly reduced. When rain falls in these densely built environments, storm drains collect and channel this excess water away, preventing accumulation that could lead to flooding.

By providing a systematic way to redirect stormwater, these drains not only help protect property and infrastructure from water damage but also reduce the risk of overwhelming local waterways with sudden surges of runoff. This is essential for maintaining the overall health of the urban environment, minimizing the impact of heavy rains, and promoting public safety. In summary, the key function of storm drains is to manage stormwater and mitigate flooding, which is why this answer is the most accurate in the context of urban areas.
