Stump Grinding in Merritt Downs, Old Hickory

The tree is in the strip between the sidewalk and the street

Merritt Downs is one of very few Old Hickory subdivisions platted with continuous sidewalks, and when it was built in the 1990s the strip between walk and curb was planted the whole way along - mostly Bradford pear, with red maple and flowering cherry mixed in. Roughly a hundred and twenty houses, one planting list, one outcome.

Those pears are now doing what pears do. They split, they get taken down, and roots that spent twenty-five years growing in a four-foot band of compacted fill have lifted the sidewalk panels either side into a trip edge. So you have a stump you cannot mow around, a raised slab the mail carrier keeps mentioning, and a strip of ground that may or may not actually be yours.

Grinding it out is straightforward. Grinding it out without cracking the concrete on both sides is the part worth paying attention to.

Grinding in the right-of-way without breaking the slab

The strip between walk and curb is Metro right-of-way in most cases even though you mow it, which affects who is responsible more than it affects whether the work can happen. Practically, the constraints are the two concrete edges.

We set the machine on the street side and swing in, rather than sitting on the sidewalk where weight can rock a panel that is already lifted. The wheel stays off the slab edge, and where a root runs directly beneath a panel we take it back to the edge and stop instead of undercutting the bearing below the concrete - hollow out under a sidewalk and you have swapped a raised panel for a broken one. Cones and a spotter go out while we work, because these streets have kids on bikes.

One planting list, four species, four timelines

The flowering cherries were always the short-lived ones. Fifteen to twenty years is a normal span for them and most are gone already. Bradford pear is failing now, in the way pears fail: a clean split through the middle of the trunk in a storm. Red maple is fine and will be for decades yet, though its surface roots are starting to argue with the walk in the wetter sections.

Willow oak is the one to think hard about. Where the builder used it, those trees are only now hitting stride and they will carry the neighbourhood's canopy for the next fifty years. If a willow oak has to come out for construction, that stump is a serious hardwood grind and nothing like the pear next door, even at a similar diameter.

Twelve minutes out, so we like to bundle stumps

Merritt Downs sits at the far edge of our map, off Cascade Drive past Truxton Park, and we are honest about what that means. We will still come for a single stump, but pairing it with another address in the same week makes the scheduling work better for everyone. On a street where a dozen houses planted the same pear in the same year, that is rarely difficult to arrange.

Parking is the other note. With sidewalks and quarter- to third-acre lots there is no dropping a trailer on the verge, so we work from the street and keep the travel lane passable. School traffic around Andrew Jackson Elementary and DuPont Tyler Middle makes a mid-morning start the sensible choice. Mailboxes are the other small thing. On a street with a continuous walk, the box post often sits within a couple of feet of the strip tree, and we would rather pull it and reset it than clip it with a wheel.

Sidewalk-strip work in Merritt Downs

• Machine positioned from the street side so no weight rests on a lifted panel
• Roots taken back to the slab edge and never undercut beneath the bearing
• Cones and a spotter out while the wheel runs, with the travel lane kept open
• Lifted panels photographed beforehand if you plan to raise it with Metro
• Pear, cherry and maple bundled across neighbouring addresses to cut the per-stump price
• Mid-morning starts around the elementary and middle school run
