DISTURBED AREA
An area subject to earthmoving activity.
DIVERSION TERRACE
A channel or ditch and a ridge constructed across a sloping land surface, on the contour or with predetermined grades, to intercept and divert surface runoff before it gains sufficient volume and velocity to create harmful erosion.
