Which statement best describes why stabilization BMPs are used on active construction sites?

• A. They provide decorative features during construction.
• B. They reduce the need for drainage planning.
• C. They help minimize sediment transport by stabilizing soils.
• D. They replace the need for permanent stabilization later.

Answer: (C)

Stabilization BMPs are used on active construction sites to keep soil in place and prevent erosion, which in turn minimizes sediment carried by runoff. When grading and earthwork leave soils exposed, they are easily detached and transported by rain and surface water. Applying stabilization measures—like temporary seeding, mulch, erosion blankets, or other surface-stabilizing practices—helps the soil resist detachment and runoff, protecting water quality and helping meet stormwater permit requirements. These are temporary controls used until permanent stabilization (such as established vegetation) is achieved, and they do not serve decorative purposes, do not replace drainage planning, and do not eliminate the need for future stabilization.
