Preserve natural vegetation where possible. Good planning reduces costs, minimizes maintenance and repair, and makes structural erosion control measures more effective. When construction activities and erosion expose infertile subsoil, saving the original topsoil for later replacement may be helpful in establishing vegetative cover. Fertilization is frequently required to achieve adequate vegetative growth. Vegetation on a slope.
Some erosion is unavoidable.
The resulting sediment must be trapped on the site. Sediment fences, traps, and basins must be properly maintained, regularly inspected, and cleaned as necessary. Dispose of the sediment removed during cleaning in a place where it will not flow back into the control structure. Temporary sediment trap. Minimum flood pool volume is 1,800 cubic feet per acre of drained area.
