Erosion control protects against soil loss from wind and water. Temporary erosion control includes silt fences, sediment basins, and soil stabilization. Permanent erosion control uses vegetation and site design to prevent runoff. Vegetation including grasses, shrubs, and trees provides root systems holding soil in place. Root density increases with time as plants mature. Native plant selection supports local ecosystems and requires less maintenance. Trees provide the greatest erosion control and long-term site stability. Shrubs provide mid-story protection. Grasses provide ground cover and shallow root networks. Hydroseed or hydroseeding applies grass seed, water, and tackifier in a single operation. Hydroseeding accelerates grass establishment. Tackifier helps seed stick to the slope preventing movement. Temporary seeding with fast-growing grasses stabilizes slopes during construction. Permanent seeding with native plants occurs after construction. Slope grading affects drainage. Convex slopes shed water quickly. Concave slopes accumulate water creating gullies. Proper grading prevents water concentration. Surface roughness (mulch or straw) reduces runoff velocity. Rougher surfaces allow more water infiltration. Geotextiles prevent soil movement while allowing water percolation. Coir (coconut) fiber matting biodegrades over time allowing vegetation establishment. Permanent vegetation maintenance includes watering, weed control, and replacement of dead plants. Establishment period (typically 1 to 2 years) requires care. Once established, vegetation requires less maintenance.
