By promoting soil stability, supporting healthy vegetation, and retaining water, topsoil acts as a natural filter, reducing sediment runoff and pollutant discharge into nearby water bodies. As MS4s sprawl into farmland, which becomes a major source of nutrient and sediment pollution, the importance of soil management (i.e., cover crops, etc.) becomes paramount.
For these reasons, preserving and restoring topsoil on construction sites plays a crucial role in successful stormwater and erosion management. It not only mitigates the impact of construction activities but also supports sustainable land development practices.
