San Francisco’s Millennium Tower, a 658-ft-tall residential building at Mission and Fulton streets, has settled 16 in. and tilted 2 in. toward the northwest since completion in 2009 while garnering lawsuits and recriminations about the foundation design and possible impact of an excavation for the nearby Transbay Transit Center. But at the street level, the settlement is less noticeable, evidenced by sidewalk sagging and engineers’ marks. Stanford engineering professor Eduardo Miranda explains that the tower is in an area that is generally sinking as well as being on a podium that extends beyond its visible footprint. Distortion shows up over a broader area, under the sidewalk and streets.
