What is the typical sequence for implementing erosion control measures as a project progresses?

• A. Site clearing; immediate permanent stabilization; dewatering; post-construction maintenance.
• B. Pre-disturbance planning; final stabilization; progressive disturbance; temporary measures; long-term maintenance.
• C. Initial disturbance; pre-disturbance planning; interim stabilization; final site stabilization.
• D. Pre-disturbance planning; installation of initial BMPs; interim stabilization; progressive disturbance with phased stabilization; final site stabilization.

Answer: (D)

The main idea is staging erosion control from planning through final stabilization as the project progresses. You start with pre-disturbance planning to identify site conditions, choose appropriate BMPs, and align with permits and sequencing. Then you install the initial BMPs early so there’s control in place before significant soil exposure. As work continues, interim stabilization is used to protect disturbed areas that can’t be immediately permanently stabilized, reducing sediment runoff in the meantime. With progressive disturbance, the project advances in manageable stages, applying stabilized measures to each new area as it’s disturbed, so erosion control keeps pace with construction. Finally, once all work is finished, you achieve final site stabilization to establish permanent cover and long-term erosion control. This sequencing ensures control is proactive, continuous, and scalable with the project’s progression. Other sequences either move into disturbance or permanent stabilization too early, skip the staged stabilization approach, or omit planning and early BMP installation, which would leave erosion control behind the pace of construction.
