Alpharetta Stump Grinding
After a tree comes down, the stump is usually left about a foot tall unless grinding is part of the job. A stump grinder uses a spinning cutter wheel to chip the stump and surface roots below grade so the area can be leveled, seeded or replanted. It is faster and far less disruptive than digging out the root ball, which is why it is the standard approach on most Alpharetta lots.
Here is what grinding involves, what it costs, and how it fits with the City's tree rules.
What grinding removes
Most grinders reduce the stump to chips several inches below the surface, commonly 4 to 6 inches, deeper on request. Large surface roots near the stump are ground too. Deeper roots stay in place and decay slowly. The resulting pile of chips and soil can be used as mulch elsewhere, or raked out and hauled away if you plan to sod or plant in the spot.
How stumps are priced
Published 2026 estimates put stump grinding at about $120–$400 per stump, often calculated at roughly $2–$5 per inch of diameter, with minimum charges common. When several stumps are ground on one visit, the first is priced higher and additional stumps cost less. Hard-to-reach stumps on slopes, in fenced backyards or next to foundations and utilities take longer and cost more.
Permits and the City
Grinding an existing stump is generally not tree removal, but the removal of the tree itself is regulated by UDC §3.2.4 and typically needs a permit. If you are having a tree removed and ground in the same visit, make sure the removal permit is in place first. Call Georgia 811 before grinding near property lines or where utilities may be buried.
Replanting after grinding
Alpharetta expects lots to keep a minimum tree density, which the City's guidance document sets at 130 inches per acre. If removal leaves a lot below that standard, the City may require replanting. Grinding the old stump deeply and removing the chips gives a new tree a better start. Wait for chips to settle and add topsoil before planting.
Grinding vs. full removal
Full stump removal pulls or digs out the root ball, leaving a large hole to backfill. It is usually only needed when the space will be built on, such as for an addition, patio or pool. For lawns and planting beds, grinding is sufficient and costs less.
