When should an inspector ensure that a Best Management Practice (BMP) is not installed during construction?

• A. Before the contributing drainage area is stabilized
• B. After the contributing drainage area is stabilized
• C. When construction is completed
• D. Before the first inspection

Answer: (A)

The rationale behind ensuring that a Best Management Practice (BMP) is not installed during construction prior to stabilizing the contributing drainage area is rooted in the effectiveness and purpose of BMPs. BMPs are designed to control stormwater runoff and improve water quality by managing how water interacts with the landscape. If they are installed before the contributing drainage area is stabilized, the BMPs may be subject to increased sedimentation and destruction from ongoing construction activities. This can lead to ineffective sediment control and potential downgrading of water quality, defeating the purpose of implementing BMPs in the first place. Stabilization of the area before BMP installation ensures that they function properly and are not compromised by construction activities, leading to a more effective management of stormwater runoff. In comparison, the other options refer to either post-construction scenarios or conditions that do not align with the timeline of construction activities affecting the functionality of BMPs. Operations such as installing BMPs after stabilization can ensure that they perform adequately in managing runoff, while ensuring they are not compromised during construction.
