What is the main purpose of a stormwater management plan?

The main purpose of a stormwater management plan is to describe how stormwater will be managed to meet regulatory requirements. This includes detailing the strategies and practices that will be employed to control the quantity and quality of stormwater runoff from a site, ensuring compliance with local, state, and federal regulations designed to protect water quality and manage flood risks. A comprehensive stormwater management plan takes into consideration various factors, such as site characteristics, potential sources of pollution, and the effectiveness of the proposed management practices.

While drainage system designs, construction materials, and inspection schedules are important aspects of stormwater management, they serve as components within the larger framework of the plan. The overarching objective remains to effectively manage stormwater runoff to minimize its impact on the environment and adhere to legal mandates. Therefore, the correct choice focuses on the regulatory compliance aspect, which is foundational to any stormwater management strategy.
