A view of construction and access improvements at Tom Wallace Lake, part of the Jefferson Memorial Forest south of Louisville, Kentucky. A silt fence is visible on the lake to control sediment run off from construction activities.

Erosion control measures are essential at construction sites to prevent soil erosion, sediment displacement, and environmental damage. Common erosion control features include:

1. Silt Fences: Temporary barriers made of geotextile fabric that trap sediment while allowing water to flow through. Installed along site perimeters or downslope areas.
2. Sediment Basins and Traps: Structures designed to collect and settle sediment-laden runoff, preventing it from entering waterways.
3. Erosion Control Blankets: Biodegradable mats or nets that stabilize disturbed soil and protect against water and wind erosion.
4. Straw Wattles (Fiber Rolls): Cylindrical rolls of straw, coconut fiber, or similar material placed on slopes to slow water flow and trap sediment.
5. Check Dams: Small, temporary barriers placed in drainage channels to slow water flow and reduce erosion.
6. Vegetative Cover: Planting grasses or other vegetation to stabilize soil and minimize erosion. Often used for long-term control.
7. Riprap: Layers of large stones or rocks placed in areas of high water flow to reduce erosion and stabilize slopes.
8. Diversion Channels: Trenches or channels that redirect stormwater away from vulnerable areas to minimize erosion.
9. Dust Control Measures: Spraying water, using mulch, or applying soil binders to reduce wind erosion.
10. Gravel Construction Entrances: Stabilized entry points for vehicles to reduce the tracking of sediment onto nearby roads.

These measures are often used in combination to create a comprehensive erosion and sediment control plan for construction sites.
