Stump grinding in Jacksonville, priced in seconds

This is the one question both Jacksonville contractor FAQs reviewed for this page chose to answer, and locally the honest answer turns on the soil. The ground under most of the metro is deep siliceous sand from lower coastal plain marine terraces, described in the USDA-NRCS Mandarin and Pottsburg series descriptions, both of which are typed in Duval County. Sand has almost no cohesion, so the walls of a ground-out hole slump, the spoil volume is larger than the stump was, and the backfill keeps settling for months. Ask specifically how the hole will be backfilled and whether soil is being brought in, because that matters more here than it would on clay.

Two Jacksonville operators independently publish 6 to 12 inches below grade as their standard, one of them adding that this is sufficient to allow new grass growth, landscaping or hardscape installation. There is a local ceiling on going deeper. The USDA-NRCS Pottsburg series description records a seasonal high water table at 0 to 24 inches from February to September or December to May depending on position, so on poorly drained flatwoods lots a deep grind in the wet season is working in saturated sand and the spoil turns to slurry. On Mandarin soils the constraint is different: the cemented spodic horizon starts less than 30 inches down and is much harder than the sand above it.

No, and in Jacksonville the gap between the stump and the root system is unusually wide. UF/IFAS Duval County Extension puts most tree roots in the upper 12 to 18 inches of soil, extending three to four times beyond the drip line. Grinding takes the stump and the flare within reach of the wheel; the lateral roots stay in the ground and decay over years. On a mature live oak that matters for price, because UF/IFAS describes large surface roots that lift sidewalks, curbs and driveways, so the area to be ground is much wider than the trunk. On sweetgum it matters for regrowth, because shoots rise from those residual roots.

Diameter matters least on small stumps, because published Jacksonville per-inch rates of 2 to 3 US dollars mean a 10-inch stump prices out below the 76 to 100 US dollar minimum service charge a local page quotes. What moves the number is access, species and disposal. One Jacksonville company states it needs 36 inches of gate width to reach most backyards, which is the practical go or no-go for a walk-behind machine. Haul-away is a real line item at 50 to 150 US dollars because the city will not collect contractor-generated tree waste. Palm stumps are quoted separately at 100 to 300 US dollars. These are researched ranges from contractor pages and national estimators dated 2025 and 2026, not a quote.

They stay on your property unless you pay to have them taken, and Jacksonville has a specific regulatory reason for that. The City of Jacksonville states it is not responsible for picking up tree waste generated by a tree surgeon or similar commercial entity, so a contractor's grindings cannot go out with the weekly yard waste, which is itself capped at six inches diameter, five feet in length, 40 pounds per item and five cubic yards. Practice varies between local firms: one offers the homeowner a choice of leaving the mulch or having it hauled, another markets removal and soil backfill as a point of difference. A do-it-yourself homeowner can self-haul to Trail Ridge Landfill in Baldwin, where Saturday residential loads are 1 US dollar for the first 500 pounds.

There is no waiting period in Jacksonville's code, because the code does not address stumps at all. Chapter 656, Part 12 regulates acts that physically remove a protected tree or cause a tree to die, and a stump is neither. The two-visit pattern behind this question is usually about scheduling and equipment rather than rules, since a felling crew and a grinding machine are often separate trips. One obligation does carry over regardless of timing: Sunshine 811 needs a minimum of two full business days before you dig, not counting the day you contact them, and locate marks stay valid for 30 calendar days, so a grind scheduled well after the felling may need its own ticket.

Physically yes, and both the depth and the backfill decide how well it takes. Local standard depth is 6 to 12 inches below grade, described by one Jacksonville operator as enough for new grass, landscaping or hardscape; a replacement tree wants more room than turf does, so say so before the quote. Regulation is unlikely to be your obstacle on a normal lot, since Sec. 656.1205(b)(1) exempts trees on an occupied single-family lot that cannot be further subdivided. If the property is in the Ponte Vedra Zoning District of St. Johns County rather than Duval County, the rules are different and mitigation planting can be required at up to 2 to 1.
