Certified Storm Water Operator Practice Exam

What is required for good site stabilization?

1. Installation of temporary fencing

2. Establishment of vegetation

3. Completion of water quality testing

4. Finalizing permit audits

The correct answer is: Establishment of vegetation

Good site stabilization is primarily concerned with preventing soil erosion and managing stormwater runoff effectively. Establishing vegetation plays a crucial role in this process because plants provide ground cover that helps hold soil in place, reducing the risk of erosion caused by wind and water. The root systems of plants enhance soil structure and integrity, allowing for better water absorption and helping to control sediment movement. In contrast, while temporary fencing can help protect areas from disturbances during the stabilization process, it does not directly contribute to the stabilization of the soil itself. Water quality testing is essential for understanding the impacts on local water bodies but does not prevent erosion or stabilize the site. Finalizing permit audits is an administrative task necessary for compliance, yet it lacks a direct impact on the physical stabilization of the site. Therefore, the establishment of vegetation is the most critical requirement for achieving effective site stabilization.
