Boston's Back Bay has a similar problem of keeping old wood pilings wet. I'm sure many old cities have similar areas.

  In Amsterdam this is now a serious problem. The pilings there are getting really old and the water table has been changing, sometimes quite dramatically because of deep construction and the waterships's decisions to either purposefully lower it and then later reversing that decision again. This has caused pilings to become exposed, and then to be dried out, re-exposed and dried out again, with significant chances of rot as a result. Lots of historical buildings have had to have their foundations re-done which is super hard given the limited access. Some very ingenious machinery has been built, including a pile driver that is small enough to take under an existing building that drives new piles in situ. The whole thing can be disassembled and then re-assembled under the building. http://funderingstechniek.com/foto/carre3.jpg http://funderingstechniek.com/foto/carre3.jpg

  Venice has this problem. The whole city was built atop wood piles driven into marsh. The Sea has been trying to take the city back ever since.

    Eventually it will succeed.
