What is a best management practice (BMP) in stormwater management?

A best management practice (BMP) in stormwater management is a method designed to minimize both the quantity and quality of stormwater runoff. This approach is essential to protecting water quality and managing the impacts of stormwater on the environment. BMPs can include a variety of techniques such as the use of vegetated swales, retention ponds, infiltration basins, and other practices that help capture and treat stormwater before it enters natural water bodies. By implementing BMPs, organizations can address pollution concerns, reduce flooding, and enhance groundwater recharge, ultimately contributing to more sustainable stormwater management strategies.

The other options are not representative of the true purpose of BMPs. Chemical treatments are just one component of stormwater management and do not encompass the broader goal of minimizing runoff. Increasing stormwater runoff contradicts the primary intent of BMPs, which is to manage and mitigate it. Finally, while BMPs can be part of regulatory requirements, they extend beyond mere compliance; they also serve as proactive strategies for environmental stewardship.
