PA DEP STANDARD CONSTRUCTION DETAIL # 4-8 Reinforced Silt Fence (30" High) Fabric shall have the minimum properties as shown in Table 4.3. Fabric width shall be 42” minimum. Stakes shall be hardwood or equivalent steel (U or T) stakes. An 18” support stake shall be driven 12” minimum into undisturbed ground. Silt fence shall be installed at existing level grade. Both ends of each fence section shall be extended at least 8 feet upslope at 45 degrees to the main fence alignment (Figure 4.1). Sediment shall be removed where accumulations reach half the aboveground height of the fence. Any section of silt fence which has been undermined or topped shall be immediately replaced with a rock filter outlet (Standard Construction Detail # 4-6). Fence shall be removed and properly disposed of when tributary area is permanently stabilized. 363-2134-008 / March 31, 2012 / Page 80
