A similar feat was accomplished in Chicago.
"During the 1850s and 1860s, engineers carried out a piecemeal raising of the level of central Chicago. Streets, sidewalks, and buildings were physically raised on jackscrews."

I once lived in a building that connected to the pedway, so I was able to dress in shorts and a T-shirt in a Chicago winter, navigate underground through the pedway to the Blue Line, then take the Blue Line to O'Hare for a flight to Tampa.
The train part was a bit chilly, but it was better than having to drag a winter coat with me on the plane.
