At the beginning of the 1800s, Lower Manhattan was starting to get expanded via landfill. As the neighborhood was (literally) growing, Stone Street started becoming increasingly commercial and many residences on and around Stone Street were subdivided.
In 1811, the common council approved petitions to widen Stone Street, and the street was expanded by about 4 feet for $150,000 (equivalent to about $3.4 million in 2023).
