New Construction and Teardown Stump Removal in Nashville

Teardown Stump Removal on a Split Nashville Lot

Over the decade to 2018 this city gave up better than 918 acres of canopy, and the losses were not spread evenly. They landed hardest where growth was fastest and where incomes were lower and renting more common. The mechanism is not mysterious. Tennessee's Horizontal Property Regime lets one existing residential parcel be divided into multiple parcels with shared general common elements, so a single lot ends up carrying two tall narrow houses, and that product is thickest in exactly the places with the oldest trees: 12 South, The Nations, East Nashville and Germantown.

What that does to the ground matters as much as what it does to the canopy. Down comes the old tree. Off comes the topsoil. Tracked plant then works the bare clay until the whole parcel is compacted, and any survivor along the boundary gives up its root zone to a foundation and a driveway that were not there in spring.

So the stump we are asked to grind on an infill lot is usually sitting in compacted fill rather than in native soil. It grinds differently, the hole drains badly, and the backfill settles on a different schedule than it would in undisturbed Talbott clay. That is worth knowing before a driveway goes over it.

Grinding Depth for a Footing, Not for a Lawn

A landscaping grind is six to twelve inches below grade and it is the right answer for turf. It is the wrong answer for a build, and the difference is not a preference, it is a callback in three years.

On an active site the depth is set by what is coming: below the footing line where a foundation is going, below subgrade where a driveway or an apron is going, below the slab where a slab is going, and the lateral flare comes out with it rather than being left as a ring. Buried wood under structural fill decays on its own timetable and leaves a void, and a void under a new concrete drive in The Nations shows as a crack long after everybody has moved on.

Say this clearly to whoever is doing the site work: grindings are not structural backfill. They compress and they rot. The hole gets clean fill compacted in lifts by the excavator, and we take the spoil out of the way so that can happen. We raise it at the quote rather than assuming the builder already knows, because about half the time nobody has had that conversation.

What Nashville Makes You Replant After Stump Removal

Two things surprise people in opposite directions. The first: section 17.40.470, the removal permit everyone worries about, simply does not reach a single-family or duplex residence. Its subjects are commercial developers, commercially zoned parcels and multi-family projects. Pull a tree out of your own back yard and no such permit exists for you to fail to get.

The second is that BL2022-1409, effective 15 March 2023, still reaches an individual single-family or duplex lot through the replanting side. That ordinance requires one new two-inch caliper canopy tree for every twenty feet of frontage, alley frontage excluded, up to eight per lot, doubled on cul-de-sac lots, demonstrated before the certificate of occupancy and with a three-year establishment period on the new trees.

Development parcels get the Tree Density Unit math instead. Anything six inches DBH and up counts as protected, an inventory and a landscape plan are filed, save areas get protection fencing, and a notice board goes up on the property a full week before equipment arrives. Start early and it is fifty dollars a day, per violation. Take a tree you had no permit for and the replacement is calculated at two caliper inches back for every caliper inch removed. The ordinance also puts requirements on the contractor: ISA credentials and a million dollars of cover.

Stump Spoil and Metro's Grading Permit Threshold

Two numbers trigger a Metro Water grading permit: a hundred cubic yards of material moved, placed or disturbed, or ten thousand square feet of ground laid open. Fill has its own ceilings as well, nothing going onto a surface pitched steeper than five to one and no finished slope past one in three.

A single stump never gets near those numbers. A full-lot clearance on a Green Hills teardown, where a 48-inch tulip poplar and three oaks come out together and the whole parcel is regraded for six thousand square feet of house, can. That is a permit conversation rather than a rake-and-go, and it belongs to the site contractor rather than to us, but the spoil volume we generate is part of the arithmetic and we will tell you what it is.

The erosion obligation does not wait for a permit either way. Loosened soil and fresh grindings piled at the top of a slope above a street inlet in Sylvan Park is a stormwater problem whether or not anything was permitted, and denuded ground has to be stabilized within fifteen days. On an active site that usually means the spoil leaves on our truck the same day.

Points to agree with the site contractor before we unload

• Finish grade and the footing line, so depth is a number rather than a judgement call
• Whether the spoil leaves the site that day or gets stockpiled, and where it can legally sit
• Who backfills and compacts the void, and with what, because it is not going to be grindings
• Which trees on the plan are in a protection zone and must not be driven across
• Whether the lot is inside a mapped floodplain, which changes what can be placed on it
• The frontage measurement, because that is what sets the replanting count at occupancy
• Site access and staging, since a half-built infill lot has no spare width at all
