Primarily the O and A horizons will be lost.

- O horizon (surface organic litter) is removed with vegetation clearing.
- A horizon (topsoil, organic‑rich mineral layer) is usually stripped during clearing and grading and/or eroded soon after.
- The E horizon (eluviated zone) can also be removed or severely disturbed where present, especially with heavy grading or erosion.

Deeper B and C horizons generally remain unless there is extensive excavation for foundations, basements or road cuts.
