What practices protect soils when heavy construction equipment is operating?

• A. Minimize exposed soil, use stabilized work areas, limit clearing in phases, and control runoff with BMPs.
• B. Expose as much soil as possible to accelerate work.
• C. Clear entire site at once to reduce duration.
• D. Rely solely on natural processes to control erosion.

Answer: (A)

Protecting soils under heavy construction hinges on limiting how much soil is exposed and actively controlling how water and sediment move across the site. The best approach is to minimize exposed soil, use stabilized work areas, limit clearing in phases so large areas aren’t disturbed all at once, and employ runoff controls (BMPs) to keep sediment from leaving the site. Keeping soil covered or protected reduces detachment; stabilized work zones provide a durable surface that resists erosion and supports equipment; phasing clearing shortens the duration any soil is exposed; and BMPs like silt fences, sediment basins, stabilized entrances, and inlet protections slow, trap, and treat runoff so less sediment reaches streams. Together, these practices address erosion at its source and support regulatory expectations for sediment control. Options that maximize exposed soil, clear the entire site at once, or rely on natural processes alone would significantly raise erosion risk and are not suitable.
