Certified Storm Water Operator Practice Exam

On sites with fine textured soils, the emphasis on runoff and erosion control is particularly important due to the physical properties of these soils. Fine textured soils, such as clay, have smaller particles that can hold water more effectively but are also more prone to erosion when disturbed. This means that without appropriate controls in place, fine soils can easily be washed away by surface water runoff, leading to increased sedimentation and degradation of water quality in nearby water bodies.

Erosion control practices may include the use of silt fences, sediment basins, and other best management practices that help retain soil in place and minimize the impact of storm water runoff. By prioritizing runoff and erosion control, it becomes possible to prevent soil loss and protect both the project site and the surrounding environment. Addressing these concerns helps ensure that the land remains stable and that the water systems are not adversely affected by excess sediment.
