So Chicago will sink about an inch this century. I don’t think we need to worry about this. I own a home in Chicago that is 130 years old. The foundation is fine. No cracks. The brick street in front of me looks great. Its over a hundred years old. No flooding. Mostly because of good water management and the fact that we live on a great lake which gives us a quadrillion gallons of potable water that is constantly replenished. We don’t use water from the ground. We don’t pull oil or coal from the ground. If anything we had add with land fills,
A lot of the terrain in the Chicago area is actually still rising after the glaciers melted.
