'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 Greenfield — Greenfield Residential Historic District, Brandywine Village and Fieldstone included, that's normally a tree trimming job at $250–$1,400. Not urgent.
Why this comes up in Greenfield
Greenfield Power & Light — a city-owned municipal utility, not an investor-owned one — serves customers inside the city limits from three distribution substations, and its own page links to Indiana Municipal Power Agency (IMPA) information for wholesale power. That matters for tree work: the IURC's vegetation management rules apply only to investor-owned utilities (AES Indiana, Duke, I&M, NIPSCO, CenterPoint/Vectren), so GP&L sets its own line-clearance practice — confirm it with the utility directly. Outside the city limits, NineStar Connect is the electric provider.
Greenfield's canopy
Greenfield was not one of the 23 communities in the Indiana DNR street tree sample, so there is no published species breakdown — the honest picture is a two-tier canopy: mature shade trees dating to the historic district's roughly 1880-1947 build-out over those streets and Riley Park, versus small suburban stock in the newer additions. Statewide, Indiana street tree populations run about 18% silver maple and 34% maple overall; Callery pear is common in 1990s-2000s plantings and as of 2026 is still legal to sell in Indiana, with the amendment that would add it to the Terrestrial Plant Rule pending since 2021 — re-check IDNR before advising a customer.
Hancock County rules
Greenfield has a real tree code — Chapter 97 — but it governs street trees, not your back yard. Under § 97.07 nobody may prune, spray or treat a street tree, or hire someone to, without the city first issuing a right-of-way permit (issued to property owners or certified arborists), and no street tree may be removed without that permit except in an emergency; a City Tree Commission oversees the program and Chapter 97 also sets street tree species, spacing and clearance standards. Those provisions could not be verified against a retrievable copy of the code — confirm with the city before quoting right-of-way work. There is no Greenfield permit requirement for removing a tree on private property, and Indiana has no statewide one.
The tree lawn in Greenfield
The planting strip is city right-of-way and Greenfield actively controls it — the Chapter 97 right-of-way permit is the mechanism, species and spacing come from the ordinance and the city's Public Improvement Design Standards manual, and the City Tree Commission has a say. This is stricter than most Hancock County jurisdictions, where the strip is nominally public but effectively unmanaged.
