What is the main function of a stormwater management plan?

• A. To recycle water for industrial use
• B. To identify potential construction projects
• C. To reduce pollutants in stormwater runoff and manage the quantity of runoff
• D. To install underground drainage systems

Answer: (C)

The main function of a stormwater management plan is to reduce pollutants in stormwater runoff and manage the quantity of runoff. Stormwater runoff occurs when rain or snowmelt flows over impervious surfaces, collecting pollutants such as sediments, nutrients, heavy metals, and hydrocarbons along the way. A well-designed stormwater management plan aims to mitigate these negative impacts on water quality and prevent flooding by implementing best management practices (BMPs) that may include green infrastructure, retention basins, and the use of vegetated swales. This focus on pollutant reduction and runoff management is crucial for protecting water bodies and maintaining ecosystem health. By addressing both the quality and quantity of stormwater, these plans ensure compliance with local, state, and federal regulations, promoting sustainable urban and environmental practices.
