Best Practices for Sediment and Erosion Control

Sediment and erosion control is a critical aspect of construction, landscaping, and stormwater management projects. Effective measures prevent environmental degradation, maintain compliance with local and federal regulations, and protect nearby water bodies from sediment pollution. In this guide, we explore what sediment and erosion control entails, why it matters, and best practices to ensure success.

What Is Sediment and Erosion Control?

Sediment and erosion control involves practices designed to prevent soil erosion and manage sediment runoff. Erosion occurs when wind, water, or other natural forces displace soil, while sediment refers to the soil particles that are carried away and deposited elsewhere, often polluting waterways.

Without proper controls, construction sites and disturbed land can become sources of sediment pollution, causing issues like:

• Clogged drainage systems
• Habitat destruction for aquatic life
• Decreased water quality
• Increased flooding risks

Why Is Sediment and Erosion Control Important?

1. Environmental Protection

Unchecked erosion can lead to sediment entering rivers, lakes, and streams, impacting aquatic ecosystems and degrading water quality. Excess sediment can block sunlight, disrupt fish habitats, and reduce oxygen levels in the water.

2. Regulatory Compliance

In the U.S., sediment and erosion control measures are often required by federal laws like the Clean Water Act. Additionally, local governments typically enforce erosion and sediment control regulations as part of construction permits.

3. Preventing Property Damage

Sediment-laden runoff can clog stormwater systems, leading to flooding and damage to nearby properties. Proper controls help mitigate these risks, protecting both public and private assets.

Best Practices for Sediment and Erosion Control

1. Install Silt Fences

Silt fences are a common and cost-effective solution to trap sediment on-site. These barriers are placed along the perimeter of construction sites to filter sediment from runoff while allowing water to pass through.

2. Use Erosion Control Blankets

Erosion control blankets stabilize soil on slopes and other vulnerable areas. Made from biodegradable or synthetic materials, they prevent soil displacement and promote vegetation growth.

3. Implement Sediment Basins

Sediment basins are temporary structures designed to capture sediment-laden runoff, allowing particles to settle before the water is discharged.

4. Hydroseeding and Hydromulching

Hydroseeding and hydromulching involve applying a mixture of seed, mulch, and binding agents to disturbed soil areas. These methods encourage rapid vegetation growth, reducing the risk of erosion.

5. Establish Vegetative Buffers

Planting vegetation along slopes and near waterways creates a natural barrier against erosion. The root systems stabilize soil, while the plants filter sediment from runoff.

6. Minimize Soil Disturbance

Limiting the amount of exposed soil during construction is a proactive way to reduce erosion risks. Use phased grading techniques to minimize the time soil remains bare.

Key Sediment and Erosion Control Products

1. Geotextiles

Geotextiles are permeable fabrics used to reinforce soil and improve drainage. They’re ideal for stabilizing slopes, roadways, and drainage channels.

2. Compost Filter Socks

These socks are filled with compost material and act as a filter to capture sediment and pollutants. They are particularly useful for perimeter control and slope stabilization.

3. Riprap

Riprap consists of large stones or boulders placed along shorelines, drainage channels, and slopes to reduce water velocity and prevent erosion.

The Role of Stormwater Management in Erosion Control

Stormwater management is closely tied to erosion control. Unmanaged stormwater can accelerate erosion and sediment transport, especially during heavy rainfall. Effective stormwater systems, including retention and detention ponds, help control water flow and minimize erosion risks.

Frequently Asked Questions

1. What is the difference between sediment control and erosion control?

Erosion control focuses on preventing soil displacement, while sediment control involves capturing displaced soil before it leaves the site.

2. How long should sediment and erosion control measures stay in place?

These measures should remain until vegetation has fully stabilized the soil or the project is complete.

3. Are sediment and erosion control measures required for small projects?

Yes, even small projects can contribute to sediment pollution. Regulations often require measures regardless of project size.
