stormwater management practices must be followed. Runoff from land disturbing activities, such as clearing, grading, the stockpiling of soil, excavating, or other construction work, should not cause soil erosion or the movement of sediment into rivers and streams. The same regulations apply to runoff from roofs, driveways, parking lots, or other impervious surfaces within the development.
The first goal is to prevent erosion. This is done by keeping existing vegetation, planting new vegetation, or using mulch. Planned parking and driving areas, before paving, need gravel down to stop erosion. Second, if erosion does occurs, one must trap the sediment before it leaves the property. This is done by using diversion dikes, channels, swales, silt fence sediment barriers, check dams of rock across swales to cut the speed of runoff, and sediment traps and basins, such as wet or dry ponds. Again, peak runoff flow must not be increased because of the development.
