In the filtering practice construction sequence, what is the first step?

The first step in the filtering practice construction sequence is to ensure that the drainage area is stabilized prior to installation. This is critical because stabilizing the area helps to minimize erosion and sedimentation during the construction process, which can negatively impact the performance of stormwater management systems. By stabilizing the site, you create a controlled environment that reduces the risk of contaminants and sediment entering the filtration systems, thereby ensuring the long-term effectiveness of these structures.

Establishing vegetation, using erosion control blankets, or implementing other stabilization measures can also help manage runoff during construction, ultimately leading to a more successful implementation of the filtering system itself. This initial step sets a strong foundation for the remaining construction activities, ensuring that the filtration process can begin under optimal conditions.
