Answered for Danville, Hendricks County (county seat) County.
Still active. It's why mature American elms are rare here now, and why the ones that survive are worth protecting. 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. A rapid one-season decline usually means removal.

Flagging — one branch yellows and wilts while the rest looks fine — then rapid decline through the crown.
A rapid one-season decline usually means removal. Fungicide injection can protect a high-value elm that isn't yet infected, but it does not rescue one that is well along.
Preventive injection every two to three years, before symptoms.
