How many inches of fabric should extend into the ground for silt fence installation?

• A. 4 inches
• B. 6 inches
• C. 8 inches
• D. 10 inches

Answer: (C)

For silt fence installation, it is important for the fabric to extend into the ground to effectively manage sediment and prevent soil erosion. The recommended depth for the fabric to be embedded is generally around 6 to 8 inches. This depth ensures that the fence remains stable and anchored, allowing it to function properly by filtering out sediments while directing water flow. The choice that indicates 8 inches of fabric extending into the ground meets standard practices, helping to ensure a more secure installation and better performance in controlling sediment during construction or land disturbance activities. By embedding the fabric at this depth, it reduces the potential for undercutting or failure of the fence, contributing significantly to its overall effectiveness as a sediment control measure.
