The stormwater management plan addresses runoff during construction or after?

• A. During construction
• B. Both during and after construction
• C. Post-construction runoff is addressed
• D. Not addressed

Answer: (C)

Post-construction runoff is addressed. A stormwater management plan is meant to describe how the site will handle stormwater after construction is finished, focusing on long-term control of both how much water runs off and what it carries. It lays out permanent best management practices (BMPs), where they’ll be placed, how they’ll operate during different storm events, and who will maintain them. The goal is to keep downstream peak flows and pollutant loads from increasing compared with pre-development conditions, ensuring the site continues to meet regulatory standards over time. Construction-phase controls are typically covered by separate erosion and sediment control plans, so the stormwater management plan concentrates on post-construction management rather than during construction.
