There are several key components of any given stormwater pollution prevention plan (SWPPP) setup, and erosion control is always high on this list. Controlling soil erosion on any construction site is vital, and there are several best management practices (BMPs) that should be closely considered within the world of erosion control.
At Cearley SWPPP, we're proud to offer the best SWPPP services you'll find around Utah, including erosion control services that range from standard erosion control to information on slope erosion control and more. We're always on top of SWPPP best management practices, including BMPs for erosion control. Here are some of the top examples of BMPS for erosion control, plus what to consider in each area.
Before we get into the specific BMPs for erosion control, let's discuss why it's important to have erosion control measures in place. Erosion can cause significant damage and harm to the environment, as well as create hazards and financial loss for construction projects. By implementing proper erosion control measures, you can prevent and mitigate these negative impacts.
For instance, erosion can lead to sediment pollution in waterways, which can harm aquatic life and disrupt the natural balance of ecosystems. It can also result in the loss of fertile topsoil, making it difficult for plants and crops to grow. In construction, erosion can cause slope failures and landslides, leading to property damage and potential injuries.
Overall, implementing effective erosion control measures not only protects the environment but also ensures the safety and success of construction projects.
Now that we understand the importance of erosion control, let's dive into some common BMPs used for this purpose.
The most common form of erosion control used in construction is a silt fence. Silt fence consists of filter fabric secured to posts, with the bottom buried in a 6-inch trench and backfilled to ensure proper anchoring and performance.
The purpose of a silt fence is to prevent sediment-laden water from leaving the construction site and entering nearby water bodies. The fabric filter allows water to pass through but traps sediment, preventing it from reaching the surrounding environment.
Though simple in design, silt fences are effective at reducing erosion and sediment runoff if installed correctly. They should be regularly inspected and maintained to ensure their effectiveness throughout the course of a project.
Sediment basins are larger-scale BMPs used for trapping sediment on construction sites. They are temporary structures placed at the lowest point of a site and in an area that is easily accessible to remove the accumulated sediment.
Similar to silt fences, sediment basins use a barrier or filter system to trap sediment and allow water to pass through. However, they have a larger capacity and can hold more sediment than silt fences.
Sediment basins should be designed according to specific site conditions and expected runoff volume. Regular maintenance is also necessary to ensure their continued effectiveness in capturing sediment.
Another BMP for erosion control that's almost exclusively found at very large sites is rock check dams, which refers to a mini dam of gravel or other rock built on drainage ditches to slow down water and trap sediment. Similar to a sediment basin, rock check dams should be designed based on the site's specific conditions and expected runoff volume.
Another major type of erosion and sediment control method is inlet protection. As the name suggests, this technique focuses on protecting stormwater inlets or drains from sediment accumulation. Inlet protection devices are installed around these areas to prevent sediment, debris, and other pollutants from entering the drain and ultimately reaching water bodies.
Inlet protection methods include silt screens, geotextile bags, and gravel bags. These devices act as filters by intercepting sediments before they can enter the stormwater system. They should be regularly inspected and cleaned to ensure proper functioning.
BMPs for erosion control also look to prevent erosion from excavated slopes. This is often done through the use of vegetation, such as grass or groundcover plants, which can help hold soil in place with their roots. Other methods include using mulch or erosion control blankets to cover and protect bare soil.
Soil stabilization not only helps prevent erosion but also promotes infiltration of stormwater into the ground, which can recharge groundwater supplies. It also improves soil quality and supports biodiversity by providing habitat for various plant species.
