A root adds diameter every year and concrete does not move aside, so it comes down to which is stronger, and a live structural root beats four inches of unreinforced slab. This is a property-damage and trip-hazard problem, not a tree-failure problem, and the tree is usually in good health. The important inversion is that the repair is what creates the hazard: the roots lifting your driveway are the buttress roots on one side of the trunk, and cutting them is precisely how a stable tree becomes an unstable one. In Plainfield — Saratoga, Sugar Grove Farms and Blackthorne included, that's normally a tree removal job at $400–$1,900. Not urgent.
Why this comes up in Plainfield
Notably, the NWS Indianapolis record of 32 Hendricks County tornadoes (1950-2025) lists no tornado touchdown at Plainfield itself — the county's tornadoes cluster north and west, at Clayton, Brownsburg, North Salem, Lizton, Six Points and Avon. That leaves straight-line wind as the documented threat here, chiefly the June 29, 2012 derecho, which crossed the whole region. The most recent county event was the April 2, 2025 EF2 at Brownsburg Airport ($1.2M), well north of town.
Plainfield's canopy
The most age-mixed canopy of the three: a genuine 1950s ring plus the pre-1900 Quaker core along Main Street (US 40) carries 60-to-90-year-old shade trees over the street, while Saratoga, Sugar Grove Farms and Legacy Farms hold 10-to-25-year-old planted stock, and the White Lick Creek bluffs hold the town's only real remnant woodland. Ash is gone here as everywhere in Indiana.
Hendricks County rules
Plainfield does not require a permit to remove a tree on private property, and its nuisance chapter goes out of its way to say so: Chapter 92's definition of "weeds and rank vegetation" excludes trees, bushes and shrubs planted or cultivated by the landowner. Trees are otherwise regulated only through development review in the Zoning Ordinance — required-yard and bufferyard landscaping scored by Plant Unit Value, an optional "Tree Save Area" credit for preserving existing stands, a ban on DNR-listed invasive plants as landscaping, and an Airspace Overlay District tied to Indianapolis International Airport that caps how tall a tree may be allowed to grow. None of these provisions could be verified against the current ordinance text — confirm section citations with the Planning Department.
The tree lawn in Plainfield
The strip between sidewalk and street is public right-of-way, but Plainfield has no municipal urban-forestry program of the kind neighboring Avon runs, and street-tree requirements appear only through development review rather than a standalone tree chapter — confirm with the Town Engineer before right-of-way work. What the town does control is obstruction: under Chapter 93 the Street Department may remove obstructions in the street without notice, and the Town Engineer administers the access-permit process for work affecting the right-of-way.
