In construction, a designated practice or structure aims to control stormwater runoff and mitigate potential pollutants from leaving a construction site. These measures are implemented to prevent erosion, sedimentation, and the discharge of harmful substances into nearby water bodies. For example, installing silt fences along the perimeter of a construction zone helps filter sediment-laden runoff, preventing it from reaching streams or drainage systems.
The employment of such methods is crucial for environmental protection, regulatory compliance, and maintaining the integrity of surrounding ecosystems. These controls minimize environmental damage and potential fines from regulatory agencies. Historically, the implementation of these systems has evolved from rudimentary sediment traps to sophisticated, engineered solutions designed to address a wide range of pollutants.
