Answered for Zionsville, Boone County.
The tree lost part of its absorbing root system and, wherever soil was compacted, the pore space its roots depend on for oxygen. Tree roots are shallow and wide — most of them in roughly the top foot of soil and extending well past the dripline — so a trench that looked comfortably far from the trunk usually was not. Compaction does comparable damage and is invisible from the surface. And roots cut on one side means anchorage lost on that side, so this is a stability question as much as a health question. In Zionsville — Austin Oaks, Brittany Chase and Rock Bridge of Zionsville included, that's normally a hazardous tree removal job at $800–$5,000. Within days.
Median construction year is about 1999 across roughly 12,000 housing units, nearly 84% of them detached single-family, with only about 5% predating 1950. The tree-relevant consequence is a large belt of 25-35 year old houses whose trees are hitting full size at once — big enough to reach roofs and service drops, old enough that original builder plantings are failing together.
Zionsville has genuinely inherited canopy, not just planted stock: Austin Oaks, off Willow Road, was built on wooded lots, so mature native trees stand over the houses rather than replacing them, and the Village core's narrow streets carry mature oak and maple. Along the Eagle Creek corridor — including the 215-acre Carpenter Nature Preserve — the mix runs to oak, maple and sycamore, with standing dead ash still coming out; the town holds Tree City USA status and plants street trees annually.
No permit is required to remove a tree on private property in Zionsville. What is regulated is the right-of-way: prior approval from the town is required to plant a tree in a right-of-way encroachment, partly so the town can verify the spot clears utility and drainage lines. The Zionsville Tree Board, established at Section 31.25 of the town code, is advisory rather than a permitting body — it counsels the Town Council and Mayor on urban forestry, acts as liaison to subdivisions on street tree planting, and works to preserve Tree City USA designation (section text worth confirming against the live code).
The town owns the curb strip outright. Per the town's own FAQ, once a tree is planted between the sidewalk and the street it is technically the property of the Town of Zionsville, because Zionsville owns that land — which is why a permit is needed to plant there in the first place. Day-to-day maintenance falls to the adjoining property owner, and the town notes that replacing a street tree after its warranty lapses is a low priority that can take years.
