Silt fence installation is a crucial construction activity everyone involved in building should be aware of. Often, people disregard this essential procedure, leading to significant environmental damages and potential legal issues. This post seeks to dive into the fascinating world of silt fences and elucidate their function, installation procedure, tools needed and legal implications.
What is a Silt Fence?
Before delving into the nitty-gritty of silt fence installation, it's essential first to understand what a silt fence entails. A silt fence is a temporary stormwater control measure. It's frequently used on construction sites to protect water quality in nearby streams, rivers, lakes and seas from sediment in stormwater runoff.
Designed primarily to intercept and slow the flow of sediments, this simple but highly efficient barrier allows sediment-laden water to seep through the fabric, allowing the solids to settle and stay behind. As a result, a silt fence helps to avert erosion, thereby maintaining the natural flavor and substance of the local environment.
Importance of Silt Fence Installation
Silt fences play a critical role in soil erosion control and sediment containment, especially in areas threatened by construction activities. Consequently, the importance of silt fences cannot be emphasized enough. Here are a few reasons why:
- Environment Protection: Silt fences protect aquatic life in downstream waters from sediment-laden stormwater.
- Legal Compliance: Construction projects are legally obligated to control run-off. Thus, silt fence installation aids in meeting these legal requirements.
- Cost-Efficiency: By controlling sediment runoff, silt fences reduce the potential costs of pollution control.
- Soil Conservation: Silt fences help to retain vital topsoil within the construction site, preventing its loss due to rain and wind.
Essential Tools for Silt Fence Installation
Like any other construction activity, proper silt fence installation requires the use of certain specialized tools. Some essentials include:
- Silt fence fabric
- Steel posts or wooden stakes
- Wire back-up (optional, but can add extra support)
- Staple gun or fencing pliers
- Sledgehammer
- Shovel or trencher
Step by Step Guide for Silt Fence Installation
Installing a silt fence might seem daunting, but with the right practice and methodology, the task becomes much more manageable. The following steps should guide you in getting it right:
Step 1: Plan the Layout
Identify the area where water runoff will happen and plan your silt fence layout accordingly. For optimum performance, place the fence across the slope, not along it.
Step 2: Dig a Trench
Using a shovel or trencher, dig a 6 inch deep by 6 inch wide trench along the line where the fence will be installed. The trench will hold the bottom of the silt fence.
Step 3: Install Stakes or Posts
Install the stakes or posts on the downhill side of the trench at intervals of 6-10 feet. The posts should be driven deep enough into the ground to hold against the pressure of sediment and water.
Step 4: Attach the Silt Fence Fabric
Attach the silt fence fabric to the uphill side of the stakes using a staple gun or fencing pliers. Ensure there is a 6 inch overlap at each post.
Step 5: Backfill and Compact the Trench
After attaching the fabric, backfill the trench and compact it. This helps to prevent water from flowing under the silt fence.
Maintenance and Removal
Like any other structure, silt fences require maintenance to perform optimally. Regular inspection, especially after rain events, should be conducted to ensure fence integrity. Remove sediments deposited by runoff when they reach half the fence height. Proper repair work should be done on breached or damaged fences.
The removal of a silt fence should only be entertained once the area it protects is stable, and vegetation is established. Upon removal, dispose of sediment responsibly, backfill and compact the trench, and restore the area with vegetation cover.
