What dimensions are required for stakes used in silt fence construction?

• A. 1" x 2" by 2 feet long
• B. 2" x 4" by 3 feet long
• C. 3" x 6" by 4 feet long
• D. 4" x 4" by 5 feet long

Answer: (B)

The required dimensions for stakes used in silt fence construction are often dictated by the need for stability and effectiveness in controlling sediment. The choice of 2" x 4" by 3 feet long stakes is appropriate because they provide a good balance between strength and weight. These dimensions ensure that the stakes are substantial enough to support the silt fence, which needs to withstand water flow, wind, and soil pressures without collapsing or becoming dislodged. The width of 2 inches allows for adequate rigidity and strength, while a length of 3 feet provides sufficient anchorage into the ground, ensuring that the silt fence remains taut and properly aligned. This configuration is commonly used and recommended in various erosion control guidelines, as it helps to create a robust barrier, enhancing its function in preventing sediment transport during storm events. In contrast, other options present either dimensions that may not provide the same level of stability or are too cumbersome for practical installation and use. Therefore, the selection of 2" x 4" by 3 feet long correctly reflects the industry standards for effective silt fence construction.
