A Comprehensive Introduction to Erosion and Sediment Control
Types of Sediment Control Barriers
Choosing the right sediment control barrier is essential for managing erosion and sediment runoff effectively. Each type of barrier offers unique benefits, allowing you to address specific challenges in your landscape.
Silt Fences and Wattles
Silt fences are some of the most commonly used barriers for controlling sediment. These fences work by slowing down stormwater runoff and filtering sediment through geotextile fabric stretched between wooden posts. They’re particularly effective for moderate slopes and perimeter control but may struggle in areas with high water flow. Wattles, also known as logs, are another option. They redirect runoff and capture heavier sediment particles. Made from biodegradable materials, wattles are often favored in restoration projects because they blend more naturally into the environment, whereas silt fences provide longer-lasting protection [2].
Erosion Control Blankets and Riprap
Erosion control blankets are designed to stabilize bare soil by covering it, allowing water to flow over the surface without causing erosion. These blankets are especially useful for steep slopes or areas prone to water and wind erosion. While they may cost more upfront compared to simpler options like silt fences or wattles, their targeted application offers strong protection for high-risk areas. For zones with heavy water flow, riprap or seawalls provide a durable solution. Made from stone or concrete, riprap reduces water energy and helps stabilize soil along riverbanks, drainage outlets, and culvert inlets [2].
Plant Barriers and Sediment Basins
Natural vegetation is a long-term approach to sediment control. Plants help stabilize soil, trap sediment, and improve water infiltration through their root systems. Combining vegetation with artificial barriers can create a balanced solution that offers both immediate and lasting erosion control. Sediment basins, on the other hand, are engineered depressions designed to allow sediment to settle out of water before it flows into sensitive areas. Together, these methods form a multi-layered defense against erosion while safeguarding nearby aquatic ecosystems [2].
Next, we’ll dive into the best practices for installing and maintaining these barriers effectively.
How to Choose the Right Sediment Control Method
Choosing the right sediment control approach is all about understanding your property’s specific needs and goals. A poor choice can lead to regulatory headaches, environmental harm, and expensive fixes.
Evaluating Your Property’s Requirements
Start by assessing your property thoroughly. Identify areas prone to erosion, analyze soil types, and pinpoint sediment sources. Pay close attention to water accumulation, vegetation, slope conditions, and grading before selecting a method [3].
Slope analysis plays a major role here. For example, sandy soils drain quickly but are highly prone to erosion, while clay soils hold water but can become unstable when saturated. Also, consider how construction activities like grading or excavation might disturb the soil [3].
Water proximity and flow patterns are equally important. Take note of nearby water sources, potential pollution risks, and sensitive spots like streams or storm drains [3]. Properties near waterways often face stricter regulations and may call for more rigorous sediment control measures.
Don’t forget about timelines. Temporary solutions, such as silt fences, work well during active construction, while permanent options like vegetation provide long-term protection. Tailor your approach to meet both short-term and long-term goals [4].
This groundwork helps you compare barrier options effectively.
Comparing Barrier Options
Once you’ve assessed your site, it’s time to weigh your options. Here’s a quick comparison of common sediment control barriers:
| Barrier Type | Cost per Linear Foot | Best Use Case | Effectiveness |
|---|---|---|---|
| Silt Fence (Type MS) | $1.99 | Sheet flow on moderate slopes | Good for temporary protection |
| Silt Fence (Type HI) | $2.58 | Standard perimeter control | Moderate effectiveness |
| Sediment Control Log (Straw) | $2.90 | Flat sites with light runoff | Good for gentle slopes |
| Sediment Control Log (Wood Fiber) | $4.29 | General purpose applications | Better durability than straw |
| Sediment Control Log (Coir) | $13.25 | Environmentally sensitive areas | Excellent for restoration projects |
| Silt Fence (Type SD) | $19.87 | High-flow areas needing maximum protection | Superior protection |
For smaller budgets, vegetative solutions like grass seeding can cost as little as $0.001 to $0.02 per square foot. On the other hand, more advanced solutions, such as retaining walls, can range from $20 to $40 per square foot or more [5]. For perspective, a 100-foot stretch of silt fence can trap up to 50 tons of sediment [7].
Silt fences are ideal for handling sheet flow but aren’t effective for concentrated water flow [6]. Depending on your site, options like fiber logs and rock berms might perform better. Heavy-duty silt fences and rock berms provide stronger protection, while fiber rolls are better suited for flatter areas [6].
If your project requires higher sediment removal efficiency, sediment traps and basins are worth considering. These can remove over 80% of sediment, with temporary traps costing around $605 each [8].
Matching Sediment Control with Landscaping Goals
Once you’ve chosen your barriers, think about how they fit into your landscape design.
Look for options that blend well with your landscape. For example, native vegetation not only helps control erosion but also enhances your property’s appearance and supports local wildlife [9].
Environmental responsibility should guide your decisions. Effective sediment control keeps soil off streets, prevents lake and river dredging, reduces algae growth, and contributes to a healthier ecosystem. With sedimentation causing an estimated $16 billion in damage annually [9], choosing eco-conscious methods benefits both your property and the environment.
"Adding vegetation to bare soil areas is the most common and natural erosion control method practiced." – Snyder & Associates [9]
Maximize your investment by designing features that serve multiple purposes. For example, diversion channels with a rubble base can filter sediment while supporting deep-rooted plants. Mulching open garden beds can protect soil, promote plant growth, conserve water, and suppress weeds [1].
Timing is everything. Install sediment control measures before starting any excavation or earthmoving. Minimizing site disturbance is crucial for effective sediment management [1].
The best strategy often combines several methods. Preserve and restore natural vegetation where possible. Use silt fences and wattles to divert stormwater runoff, and install slope barriers or erosion control mats when diversion isn’t an option. Protect water beds with riprap or vegetation barriers, and use filter fabric to safeguard storm drains [3].

Installation and Maintenance of Sediment Control Measures
Proper installation and consistent maintenance are key to effective sediment control and avoiding costly failures.
Installation Best Practices
Preparing the Site:
Clear the area of debris like branches, rocks, and unwanted vegetation before installing sediment control measures. If the soil is compacted, loosen it to ensure the barrier makes solid contact with the ground [10].
Setting Up Erosion Control Blankets:
For smaller sites, dig a shallow trench at the top of the slope to anchor the blanket securely. Line the trench with the blanket, fasten it according to the manufacturer’s instructions, and overlap edges by about 4 inches to minimize soil exposure. Refill the trench and unroll the rest of the blanket [10].
On larger sites, consider using mechanized tools for efficiency. Attach twin unroller units to an all-terrain vehicle, start at a site corner, and unroll the blanket slowly, ensuring proper overlap and fastening [10].
Key Considerations:
Evaluate factors like slope steepness, soil type, runoff potential, and the time available for vegetation growth before installing erosion control matting. For the best results, combine these blankets with vegetation and install them as soon as grading or seeding is complete [10][11].
Timing the Installation:
Install sediment control measures before beginning any excavation or earthmoving work. Plan around weather patterns, such as heavy spring rains or freeze-thaw cycles in the fall, to ensure proper timing.
Once in place, these measures need ongoing attention to stay effective.
Maintenance Tips for Long-Term Results
Regular maintenance keeps sediment control barriers functioning effectively and prevents erosion-related damage.
Frequent Inspections:
Inspect sediment control systems regularly, especially erosion control blankets. Check weekly and after heavy rainfall, focusing on areas like anchor trenches that may need re-compaction or additional soil [10]. Ensure water flows over the blankets rather than seeping underneath [11].
Clearing Sediment Buildup:
Remove sediment that accumulates and starts to block the barrier’s function. Dispose of it properly, keeping it away from waterways and storm drains.
Repairing Barriers:
Fix any damage promptly. Replace torn or worn sections of erosion control blankets, ensuring overlaps match the original installation. For silt fences, repair tears using methods recommended by the manufacturer.
Seasonal Adjustments:
Adapt maintenance routines to account for seasonal changes. Address any issues quickly to maintain the barrier’s effectiveness.
Vegetation Checks:
Since erosion control blankets work best with established vegetation, monitor plant growth frequently. Reseed areas with sparse coverage to ensure long-term site stabilization.
Proper maintenance ensures these barriers remain effective until they are no longer needed.
Safe Removal and Site Stabilization
The final step in the sediment control process involves removing temporary measures and stabilizing the site.
Achieving Final Stabilization:
Final stabilization signals the shift from temporary to permanent protection. In Maryland, this happens when all soil-disturbing activities are completed, and exposed soils are covered with a long-term protective layer [12].
Permanent cover options include well-established perennial vegetation with uniform density, or alternatives like concrete, riprap, gravel, or asphalt. For residential projects, final stabilization is reached when construction is complete, temporary erosion measures are in place, and the property is handed over to the homeowner [12].
Removing Barriers:
Once permanent stormwater systems are functioning and sediment is cleared, remove temporary barriers in stages, starting upslope and working downslope [12].
Final Inspection:
Conduct a thorough inspection to ensure all temporary measures are removed, permanent systems are operating correctly, and the site is fully stabilized [12].
