San Francisco has this problem with its Millennium Tower.
It’s sunk several inches.
It’s built on fill land in the bay.
If there’s an earthquake, what happens if it collapses (and falls into other buildings, as well)?
But, California will still have its high speed rail!
California will still have it’s high speed taxes.
<><> A resident was hitting golf balls in her $4million Millenium Tower apartment. The golf balls always landed in the same corner. Conclusion: the bldg was tilting.
<><> Sometime later, picture windows were cracking. Conclusion: engineer said the bldg’s facade was separating from the structure itself.
One would have thought CA learned a lesson after the 1906 quake that killed an untold number in the thousands. Many lessons later and in 1989 a hwy collapsed and buildings built on fill/soft sand, surprise!, fell down.
