If you walk around there you can see plaques on a few buildings marked like "-- 1917 flood level --". These can be several meters above the normal water level, and clearly so high that great damage will occur whenever that level is reached. But people keep calm and carry on living there, too low for comfort but in oh-so-cute dwellings by the river. They even park there cars down there which makes little sense. I walked there during the last historic flood, which was all of 15 months ago.
As an aside, the Thames Barrier is a fantastic sight to see, and reachable on foot from Greenwich in a few hours (take the water taxi home).
[The Thames Barrier] has closed nearly as many times in the last 10 weeks as in the whole of the 1990s.
Meanwhile, it wasn't closed at all between September 2010 and April 2012.

London and Vegas share that view in my mind. I love Vegas and London, but want to spend no more than 72 hours in each place at a time.
Unfortunately I've been living here for over three decades now...
The art. The history. The theatre. The culture, The food. (Like £2 curry in Camden Town? You can't beat it)
Is it expensive? Sure it is. Are there problems? Of course there are. But I enjoy my time there.
