Understanding soil erosion is critical to any contractor who deals with site or subsurface work. Not following proper erosion procedures can be very costly.
When we use the word erosion, we are speaking about the detachment of soil, sediment, or rock fragments caused by water, wind, ice, or gravity.
Erosion control is important for many construction activities, including removal of protective vegetation or ground cover, excavation, grading, land filling, stock piling of dirt or fill materials, and dewatering.
Nearly all city and state municipalities have ordinances in place to minimize the amount of sediment and other pollutants carried by runoff or discharged into our lakes, streams, and wetlands. The possibility of erosion affecting public storm sewers as well as right-of-ways in towns and cities is a concern that prompts inspectors to take notice of erosion control measures on construction projects when driving by.
Let’s look at a few immediate actions we can take to reduce the likelihood of problems caused by soil erosion on a job site.
The scope of work pertaining to erosion control is usually carried out by the excavating, utility, sewer and water, concrete, and landscape contractors. However, all contractors have a responsibility if they are affecting erosion. This may be spelled out in the contractor/subcontractor agreement. The site superintendant would document in the job site log all daily activities, including erosion control work.
