Beginning in 1900, Mooresville begins to undergo intense development and population growth in the area around the mill.
The earliest Sanborn Map survey of Mooresville, conducted in 1902, seems to have been prompted by the construction of Mill 2 and the expensive machinery it had installed. Here's what the 1902 Sanborn map of Mooresville says about the Mill:
