What constitutes a 'disturbed area' that requires erosion control measures?

• A. Any area outside the site limits.
• B. Any area where the ground surface has been cleared, graded, or exposed within the site limits during construction.
• C. Only areas with vegetation removal.
• D. Areas outside the construction footprint.

Answer: (B)

Disturbed area means any portion of the project site where the soil has been cleared, graded, or left exposed because of construction activities. Erosion control measures are required there because exposed soils are prone to eroding from rain or wind and can carry sediment off the site. The key point is within the site limits and tied to activities that expose or loosen the ground during construction—clearing, grading, or any ground exposure. Areas outside the site limits or outside the construction footprint aren’t subject to the project’s erosion control requirements. Simply removing vegetation doesn’t automatically define a disturbed area unless the ground itself has been cleared, graded, or exposed.
