In the standard earthwork sequence, which step directly follows drainage installation?

Explanation:
In earthwork sequencing, you want the subsurface drainage system in place and stable before the surface is finished. After the drainage installations are completed and the trenches are backfilled and compacted, the next step is to bring the site to its final elevations and slopes. Final grading ensures the designed ground contours and drainage gradients are achieved, and it prepares the surface for subsequent layers such as base, pavement, and shoulders. Clearing/grubbing happens earlier in the process, and acceptance occurs only after everything is finished and inspected, while trenching/backfilling is the activity used to install the drainage itself, not the step that follows it.
