Answered for Danville, Hendricks County (county seat) County.
Common in Indiana maples, and frequently misdiagnosed as drought stress. 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 soil-borne fungus with no cure.

What to look for
One branch or one side wilts while the rest looks healthy. Olive-green streaking in the sapwood under the bark.
Whether the tree can be saved
A soil-borne fungus with no cure. Some trees wall it off and live for years; others decline over two or three seasons. Watering and feeding buys more time than any product does.
