Impressive. I also thought someone was having a laugh when they told me about the Raising of Chicago. > During the 1850s and 1860s engineers carried out a piecemeal raising of the level of central Chicago. Streets, sidewalks and buildings were either built up, relocated, or physically raised on hydraulic jacks or jackscrews. The work was funded by private property owners and public funds. https://en.wikipedia.org/wiki/Raising_of_Chicago https://en.wikipedia.org/wiki/Raising_of_Chicago
