What is the primary aim of stormwater management in subdivision development?

The primary aim of stormwater management in subdivision development is to control runoff and minimize flooding. Effective stormwater management strategies are essential for maintaining the natural hydrology of an area. When rain falls on a developed site, impervious surfaces like roads, rooftops, and parking lots prevent water from soaking into the ground, leading to increased surface runoff.

This runoff can overwhelm drainage systems, resulting in flooding, erosion, and water quality issues in nearby bodies of water. By implementing stormwater management practices, such as retention basins, permeable pavements, and proper grading, developers can effectively control the rate and volume of runoff. This helps to protect both the infrastructure and the natural environment, ensuring the safety and livability of the community.

Other options, while potentially beneficial in certain contexts, do not address the critical functional role that stormwater management plays in subdivision development. Enhancing foot traffic, landscaping features, or reducing construction costs may be goals of a development but are secondary to ensuring effective management of stormwater to prevent flooding and environmental degradation.
