Stump Grinding in Tynewood Estates, Forest Hills
Tynewood Drive, Tara Drive and Chalmers Drive: yes, four minutes from us. Because so many of these front-yard stumps sit over the original 1961 sewer and water runs, nothing spins here until the free state locate has come back and the three-day window has run.
A forty-inch maple stump over a sixty-year-old lateral
Tynewood Estates is the most intact original pocket left in Forest Hills. Most of the houses date to 1961, the brick has never been touched, the acre-and-a-half lots are still laid out the way the developer drew them, and the front-yard shade trees are the ones that were planted when the houses were new.
That means one species over and over: big soft-wooded subdivision maples with bases that flare out three or four feet on every side. Add water oak, a few Chinese elms and the odd mimosa nobody would plant today, and you have the whole picture.
The problem is what runs underneath them. A 1961 house on this street has its sewer lateral and its water service running from the house to the street, both of which pass through the front yard, and on houses of that vintage the sewer side is often clay pipe in short sections with joints that roots found decades ago. The stump you want gone is frequently sitting right on top of the pipe that is already the most expensive thing on the property to repair.
What 811 covers on a 1961 lot, and what it does not
A Tennessee 811 request costs nothing and brings the utilities out within three working days to mark what they own - the gas line, the water main, power and communications. We file it on every job here and we wait it out, no exceptions.
What comes back marked is the utility's side of the meter. The run from your meter to your house is yours, and so is the sewer lateral from the house out to the main. Neither gets located, neither is on a public map, and on this street both are old enough that nobody living in the house remembers where they went in.
So we treat the line between the front door and the street as live ground. Where a stump sits on that path we keep the wheel shallower over the run and take the extra depth to the sides, or we probe first. It costs twenty minutes. A cracked clay lateral costs considerably more than that.
A wide flare is a wide grind
People measure the trunk at chest height and picture a hole that size. On a sixty-year-old silver maple the base is typically half again as wide as the trunk, sometimes double, and the buttress roots run out from there like the legs of a stool.
That matters twice. It makes the finished opening bigger than expected, and it makes the chip pile considerably bigger - two to three times what most people brace for. On an acre-and-a-half lot there is usually somewhere to put it, and mounding it in a back corner to break down is a reasonable, free answer.
Where the front lawn is going straight back to grass, we take the surplus with us instead, because fresh chip mixed into topsoil ties up nitrogen and new sod planted into it comes in pale and thin.
Chinese elm, mimosa, and the other 1960s tree leftovers
Alongside the maples, this era of subdivision planting left a few species that behave badly under a wheel.
Chinese elm is stringy rather than brittle. It does not chip cleanly so much as shred, and the fibres wrap the wheel and need clearing partway through. Mimosa is worse in a different way: like the callery pears elsewhere in the city it sprouts back from root pieces, so a shallow grind buys you a season and then a thicket. On mimosa we go wider than the base and follow the roots out.
Green ash is the other one on these streets, and it is on a clock of its own. Forest Hills runs an emerald ash borer program because ash here is dying, and a dead ash goes brittle quickly. Once it is dead the city's removal permit no longer applies to it, which is convenient right up until a limb comes off over a driveway.
Flag these before we grind a Tynewood front yard
- The sewer cleanout, if you can find it - it tells us the line of the lateral
- The water meter box and the direction the service runs toward the house
- Irrigation heads and valve boxes, none of which any locate service will mark
- Invisible fence wire, usually two inches down and following the property line
- Any low-voltage lighting run along the walk or the drive
- A buried propane line if the house ever had a tank
- The old clothesline or swing-set footings that half these back yards still have
What we do in Tynewood Estates
Questions from Tynewood, Tara and Chalmers
What happens if the wheel finds my sewer line?
It should not, because we plan the depth around where the run has to be and probe where we are unsure. If a line is genuinely unmarked, undocumented and somewhere nobody could reasonably expect it, that is a conversation we have honestly rather than a bill we hide from. The far better outcome is the twenty minutes spent locating the cleanout beforehand, which is why we ask.
Can you grind close to the driveway apron without cracking it?
Yes. The wheel works from the outside in and we keep the machine's weight off the slab edge, which is the part that breaks - concrete from 1961 is often only four inches thick with no reinforcement. Where roots run under the apron we shave them below the underside rather than levering them out, since pulling a root out from under a slab is what actually lifts it.
Our maple is dead but still standing. Do we need the city's permission?
Not for a dead tree. Forest Hills requires a permit for most removals at eight inches caliper and up, but trees that are already dead are exempt, as are storm-fallen ones and anything on the state's invasive list. The permit is free anyway, so if there is any doubt about whether it is truly dead, a call to City Hall settles it before a crew is booked.
Is there a discount for doing three stumps in the front yard at once?
There is, and on this street it comes up a lot because the whole cohort of trees went in together. The first stump carries the cost of getting there; each one after it is priced well below that. Three medium maples in one visit typically comes in far under three separate calls, and it means one afternoon of noise rather than three.
