Which plan addresses post-construction runoff?

• A. Erosion and sediment control plan
• B. Stormwater management plan
• C. Construction plan
• D. Post-construction management plan

Answer: (B)

Post-construction runoff requires a long-term plan that addresses how stormwater will be managed after a site is built, including the design of controls and the responsibilities for maintaining them to meet ongoing water quality and quantity goals. The stormwater management plan provides that overarching framework, outlining the post-construction controls (such as detention, infiltration, or treatment BMPs) and who is responsible for keeping them functioning over the life of the site. Erosion and sediment control focuses on preventing sediment during construction, not the long-term performance of runoff after construction ends. A construction plan covers construction activities and sequencing, not ongoing drainage performance. A post-construction management plan alone centers on maintenance tasks and may be included within a stormwater management plan, but the comprehensive document that addresses post-construction runoff in its broader sense is the stormwater management plan.
