Answered for Danville, Hendricks County (county seat) County.
The main reason mature Scotch pine is disappearing from Indiana windbreaks and old Christmas tree plantings. 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. There is no cure once symptoms appear.
Danville's canopy and what's at risk

What to look for
The whole tree browns in a single season, often starting on one side. Needles stay attached.
Whether the tree can be saved
There is no cure once symptoms appear. The tree needs removing promptly — dead pines are a fire and fall risk, and the beetles that carry the nematode breed in the dead wood.
Timing in Hendricks County (county seat) County
Remove and destroy infected trees before the following spring, when the beetles emerge.
