Construction activity is one of the major causes of sediment entering the waterways. The major reasons why construction activities lead to erosion are: exposure of bare soil areas to storm runoff, increased volume of runoff, and changes in surface water patterns adversely affecting the drainage system, slope stability, and effects on existing vegetation.

Proper management of construction activities, as required by local, state, and federal regulations, can minimize soil erosion and control sediment transport. An erosion control provision in a construction site acts as a first line of defense. If the soil is not allowed to erode, there will not be sediment to control. Despite all attempts to minimize, a construction project will most likely leave bare soil exposed to the environment. To prevent soil from leaving the site, measures such as diversion dikes, silt fences, and sediment basins are used.
