Minimizing stormwater runoff at construction sites is crucial for preventing pollution and managing water flow effectively. Implementing erosion and sediment control measures is an essential practice that helps to stabilize the soil and prevent the displacement of sediment during rainfall or storms. These measures can include techniques such as silt fences, sediment basins, and vegetative buffers, which work together to capture and hold sediment, allowing water to infiltrate it rather than running off into nearby waterways.

When erosion and sediment control measures are in place, they significantly reduce the amount of pollutants that can be carried away by stormwater and protect the quality of nearby water bodies. This is particularly important on construction sites where soil is often disturbed, increasing the risk of erosion.

Clearing vegetation entirely does not contribute to minimizing runoff; rather, it can exacerbate the problem by removing natural barriers that help to absorb rainfall. Keeping construction materials uncovered poses a risk for them to be washed away by stormwater, which can also lead to increased pollution. Limiting the use of heavy machinery, while it may have some benefits, does not directly address the need for effective erosion and sediment control, which is vital for managing stormwater runoff effectively.
