Answered for Danville, Hendricks County (county seat) County.
Central Indiana's heavy clay and high water table make this common, especially in newer subdivisions where topsoil was stripped. In Danville, the Main Street Historic District developed circa 1844–1920 across just 9 acres and 37 contributing buildings, and the Courthouse Square district circa 1865–1960 over 70 acres — those blocks hold the town's oldest and largest trees on narrow lots with sidewalks on both sides. Danville does actively manage its right-of-way canopy through a standing Tree Advisory Committee, though the specific inventory and replanting-ratio requirements attributed to Chapter 97 could not be verified. By the time the canopy shows it, the root system is already badly compromised.
Danville's canopy and what's at risk
The Main Street Historic District developed circa 1844–1920 across just 9 acres and 37 contributing buildings, and the Courthouse Square district circa 1865–1960 over 70 acres — those blocks hold the town's oldest and largest trees on narrow lots with sidewalks on both sides. Danville does actively manage its right-of-way canopy through a standing Tree Advisory Committee, though the specific inventory and replanting-ratio requirements attributed to Chapter 97 could not be verified.
What to look for
General decline, thin canopy, early autumn colour, sometimes mushrooms at the base.
Whether the tree can be saved
By the time the canopy shows it, the root system is already badly compromised. This is a stability question as much as a health one — a tree with rotten roots can look fine and still come over in a storm.
Timing in Hendricks County (county seat) County
No cure. Improve drainage, reduce load on the tree, or remove.
