How do you count "floods"? If there is one hurricane that causes floods in 3 cities, is that 1 flood, or 3?
If it's 1 - which is what I think is meant when saying "a 1 in XXX years flood" - then your comparison doesn't hold, because the number of floods isn't dependent on the number of cities, but on the distribution of cities on the land, and specifically in flood-prone areas.

IMO you need to look at something other than city limits. Cities like Houston and LA are huge cities geographically. IMO you need to look at regional and per capita impacts.
