We fairly regularly get higher tides than that, and historically it has been several feet higher on a couple of occasions. As you can see from the right hand side, there are steps, and the large railings are embedded in a raised wall, which is defence-in-depth (so to speak) for the Royal Naval College. That was built in 1690-something, so they've been expecting occasional high tides for a long time.
It may be that we get them a little more often at the level shown in these pictures. If so I'd speculate that it's a result of urbanisation and narrowing of the river upstream in Central London, as well as more river walls. My house is built on what used to be a Greenwich Marsh, so the water had more places to flood than it does now. In this Victorian map the Naval College is in the lower left - the pictures were taken just by the leftmost crease. My house is on a street that didn't exist then (built 1896), on the site in the top right corner roughly parallel where the horizontal crease is. The riverside there would have been mainly beach and mud at that time, and everything east was marshland which would have flooded. http://www.ideal-homes.org.uk/__data/assets/image/0017/301490/map-east-greenwich-01279-640.jpg The telegraph cable works just north of the crease built and laid the first transatlantic cable. It's only recently closed. It's the site of a former whaling station and gets a mention in Moby Dick.
