Tracking Installation - Answer: should be performed ASAP after vegetation is removed after
grading activities have ceased. Moving equipment up and down slope.
Surface roughening inspection/maintenance - Answer: after specified intervals and rainfall
events
- if rills appear, they should be re graded and re seeded immediately.
Temporary stabilizaton DESCRIPTION - Answer: reduce erosion and sedimentation by stabilizing
disturbed areas that would otherwise lay bare for long periods of time before they are worked
or stabilized.
