Stump grinding vs stump removal
Grinding uses a rotating cutting wheel to chip the stump and the top of the root flare down below grade, leaving the root system in the ground and a pile of chips and soil behind. Full removal takes the stump and the main roots out, which means excavation, a much larger hole and far more disturbance to lawn, paving and anything buried nearby. Grinding is the usual choice unless something specific requires the roots gone, and if the stump belonged to a public tree in Columbus, grinding it needs the same free city permit that removing the tree does.
What grinding actually does
A grinder chews the stump into chips, working down to a chosen depth below the surrounding grade. The depth is a decision, not a fixed standard: a few inches is enough to plant grass over, while replanting a tree in roughly the same spot or laying a footing usually calls for more. Agree the depth before the machine arrives, because going back over a ground stump is a second mobilization.
What stays behind is the lateral root system, which decays in place over years. What comes out is a volume of chips mixed with soil that is normally larger than people expect. Decide in advance whether the chips are hauled away, spread on site, or backfilled into the hole, and whether topsoil is brought in, because those choices change the price more than the grinding itself does.
What full removal does differently
Full removal means excavating the stump with its main roots, usually with machinery that needs an access route to the tree. It leaves a hole that has to be backfilled and compacted, and the working area around it is disturbed rather than merely dusty.
The reasons to accept that disturbance are specific: a foundation, retaining wall, driveway or pool going in over the spot, a regrade that will not tolerate buried wood, or a soil-borne root disease where leaving root material in place is a problem. Wanting the lawn to look tidy sooner is not one of them, because grinding plus topsoil gets there with a fraction of the damage.
Choosing between them
Start with what is going on that ground in the next few years. If the answer is lawn or a planting bed, grinding is almost always the proportionate job. If the answer is a structure or a hard surface, ask the contractor to say plainly whether grinding to depth is sufficient for what will sit there.
Then look at what is around the stump. Proximity to a foundation, a wall, a fence line, paving or a septic field constrains the machinery, and all of it should be discussed as part of the quote rather than discovered on the day.
Buried services are the other constraint, and the one homeowners most often overlook because the stump has been there for years. OHIO811 asks anyone planning a digging project to notify it beforehand, by calling 811 or 1-800-362-2764. Ask the contractor whether the locate has been requested and who requested it.
The Columbus rule that catches stump grinding
Stump grinding is named explicitly in the city's permit requirement. Section 912.05(A) of the current Columbus tree code bars any person from engaging in the maintenance of a tree or shrub by removal, stump grinding, application of herbicide or other chemicals, fertilizing, bracing, cabling, pruning, surgery work, cutting above or below the ground, or cutting of roots in a public street, park, or public space without first obtaining a permit issued by the department.
So a stump left over from a street or park tree is still a public tree matter, and the permit requirement does not lapse because the trunk is already gone. Excavation near a public tree carries its own trigger under 912.05(B), which matters if full removal is being considered next to one. The permit is free and the company's certified arborist applies for it; the guide on permits for tree work in Columbus sets out the process and the contacts.
