Erosion Control - Construction Sites
Preventing Storm Water Pollution at Construction Sites
The most common pollutant from construction sites is erosion, where large amounts of sediment-laden water have the potential to flow into storm drains. The property owner is the legally responsible person (LRP) and must ensure that any water that leaves the construction site meets the minimum requirements for water quality. This means that pollution prevention best management practices (BMPs) such as wattles, silt fencing and gravel bags are strategically placed to prevent sediment and other pollutants from entering the storm drains. While most of the rainfall in Sonoma County occurs between October 1st and April 30th, pollution prevention is a year-round activity. Maintaining these BMPs helps protect the health of our waterways and our community.
Here is an example of what a properly maintained construction site might look like:
