Answered for Carmel, Hamilton County.
Current passed through the tree, superheated the moisture in its path, and blew tissue apart under steam pressure. The outcome depends on where the current traveled. Along the outside under the bark, and the tree loses a stripe of cambium and often survives. Through the middle of the trunk, and the wood is fractured internally and the tree is finished whether or not it leafs out next spring. From the ground on the day of the strike you cannot tell which happened. So a struck tree is two things at once: an immediate physical hazard from loose bark and cracked limbs, and a medium-term unknown. In Carmel — Village of WestClay, Brookshire and Woodland Springs included, that's normally a storm damage cleanup job at $400–$4,000. Within days.
June 29, 2023 derecho — Carmel logged several medium-sized limbs down while the same line measured 70 mph at Indianapolis International. The July 15-16, 2024 derecho tracked directly through Hamilton County with damage at Westfield (about 55 mph), Cicero and Atlanta, including a barn hit by a gustnado near Atlanta. September 14, 2008 remnants of Hurricane Ike brought 50-70 mph gusts for hours across central Indiana.
Carmel Urban Forestry publishes an approved species list (last revised 3/28/2024) whose "Undesirable Trees" section reads like a field guide to what fills older Hamilton County streets: silver maple (shallow roots, weak wood), Callery pear, pin oak, red maple and all Fraxinus for emerald ash borer. Approved large street trees run to swamp white oak, bur oak, chinkapin oak, hackberry, male-only ginkgo, thornless honeylocust, Kentucky coffeetree, baldcypress and London planetree; note Callery pear is discouraged locally but is not yet banned in Indiana — 312 IAC 18-3-25 currently lists 44 species without it.
Carmel's code section 6-64 is titled "Planting and Removal of Trees and Shrub Regulations" and sits in the streets-and-sidewalks division of Chapter 6, alongside 6-55 covering trees and shrubs that obstruct streets and sidewalks — so the city's active regulation is aimed at the public way, plus landscape and buffer plantings approved through development plan review by Urban Forestry. I could not verify the exact text of 6-64 or confirm whether any permit applies to removing a tree standing entirely in a private back yard; contact Carmel Urban Forestry through the city's Department of Community Services before assuming, and check HOA covenants, which in most Carmel subdivisions are stricter than the city.
The strip between sidewalk and curb is city right-of-way, and Carmel Urban Forestry plants and maintains the street trees in it, including species selection. Many Carmel subdivisions layer a platted landscape easement and HOA covenants over that same ground, so two approvals can apply to one tree.
