How deep should stump grinding be specified for the intended future use?
Specify stump grinding by the intended future use and a defined reference elevation, not by an unqualified promise to grind “below grade.” A lawn, planting area, paved surface and structural foundation need different decisions. There is no single grinding depth that proves the site is ready for all of them.
Tell the contractor what will happen next
Show the planned lawn, garden, path or building location on a sketch. Ask the next contractor what remaining wood and soil conditions would interfere with that project before accepting a grinding-only proposal.
For a simple landscape finish, agree on the area to be treated, how grindings will be handled and whether soil and final grading are included. For hardscape or structural work, have the responsible designer or installer define the preparation requirements rather than relying on the tree crew's default depth.
Define the boundaries as well as the depth
Ask whether the work includes only the central stump or specified surrounding roots. Identify utilities, irrigation and neighboring trees before any below-ground operation. The one-call process and any additional locating need to be resolved before work, not after the grinder encounters an obstacle.
Make completion verifiable
Use a fixed, agreed reference for the final elevation and request photographs before backfilling. Identify who will check that the scope has been achieved and what happens when previously hidden roots or obstructions change the plan.
“Stump ground” should not be read as “every root removed” or “foundation-ready.” Write the promised outcome explicitly.
Before hiring: resolve the future use, the actual excavation boundary and the restoration responsibility. Those decisions make a depth specification meaningful instead of merely numerical.
