There are several concepts that are vitally important when it comes to stormwater pollution prevention plan (SWPPP) application in areas like construction sites, and one of the most notable here is erosion control. Soil erosion can be a major cause of environmental pollution due to resulting runoff and contamination, and preventing this from happening is a key requirement for any jobsite.
At Silver Leaf SWPPP, we're here to help clients around Utah with all their SWPPP needs, from SWPPP inspections and documentation to risk management methods, dewatering solutions and more. When it comes to controlling erosion on a given construction site, what are some of the techniques often employed effectively? Let's go over several to keep in mind for any site you're working on.
Starting with one of the simplest and most effective, mulching is a great option for controlling soil erosion. The idea is to cover up surface soils with organic materials like straw or wood chips - these types of materials absorb moisture quickly, helping keep soils in place and preventing runoff during rainstorms or other events.
In some other cases, gravel may even be used to assist with the process, helping to provide added stability and protection. These materials can be placed over bare soil if needed, or on top of specific seedlings - this will help promote regeneration during the process as well.
From a broad site perspective, one of the most important erosion control techniques employed is perimeter control. This involves managing the area of land around a given construction site, ensuring that any runoff from neighboring properties or other areas is managed properly and does not end up on your site.
Perimeter control can be implemented through various fencing techniques, soil stabilization methods, drainage systems and more. The important thing here is to have an effective prevention plan in place that can manage any runoff before it reaches your site.
One technique that's often used for both perimeter control and certain other areas of erosion control on a given site is silt fence installation. The idea here is to create a physical barrier that will filter any sediment and dirt runoff, helping keep the surrounding area clean during heavy rains or other events.
Silt fences are most often made from biodegradable materials like jute netting, with posts pounded into the ground at regular intervals around an area to form the barrier. This helps to protect the area from sediment runoff, and also prevents any silt buildup on the site which could otherwise cause erosion over time.
Another strong option for erosion control is the use of erosion control blankets (ECBs). These are made from natural materials like jute, coconut fiber or straw, and are designed to be laid over a given area to provide added protection.
ECBs can also help with soil stabilization in certain cases, as they help hold moisture while also preventing wind or rains from washing away the underlying soils. This can be a great option for areas that may not have adequate vegetation in place to provide natural erosion protection.
Speaking of vegetation, this is another key area for erosion control. By planting certain species of vegetation in the soil, you can help promote root growth and stability - this will then help keep soils from eroding during heavy rains or other events.
In addition to promoting root growth, vegetation also helps with water absorption. This means that these plants can absorb more water than bare soil, helping reduce runoff and erosion.
For many construction sites, there's often the need for temporary entries and exits to handle frequent traffic coming on and off the site. Managing these areas can be a big challenge in terms of erosion control, as they're prone to wear and tear from vehicles entering or exiting.
One good way to handle this is by using geocell materials - these are made from plastic-like membranes that can be filled with soil, gravel or other materials to help promote stability and prevent erosion. This can be a great solution for any temporary entry or exit areas on a given site.
Finally, something that's going to be vitally important for any SWPPP application is stormwater management. This includes the use of rain gardens, detention ponds and other systems to help manage runoff - all of which can assist with erosion control in certain areas.
These systems will help capture or contain water, ensuring that it does not flood an area or cause excess runoff. In addition to helping with erosion control, they can also help with other aspects of the overall SWPPP application.
The above are just a few of the key techniques involved in controlling soil erosion and implementing effective SWPPP practices. Implementing these methods on any construction site - from mulching and vegetative control to perimeter management and stormwater management - can help ensure that your site meets all necessary environmental standards. Stick to these techniques and you'll have a much better chance of keeping the area clean, safe and protected from pollution.
