'Never pruned' is not a diagnosis. Forest trees are never pruned and do fine. What differs in a yard is that an open-grown tree builds a wide, heavy, low crown with no competition to correct it, and nobody removed the competing stem at year eight when it was a five-minute cut. So what you are looking at is accumulated correctable structure plus accumulated deadwood, and the actual risk usually narrows to one or two identifiable parts: a large dead limb over somewhere people stand, or a tight V-shaped union with included bark that will split under wind or ice. In Plainfield — Saratoga, Sugar Grove Farms and Blackthorne included, that's normally a tree trimming job at $250–$1,400. 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.
