1915 flood was caused by a major hurricane that made landfall south of Galveston as a Category 3. The damage it did was severe and when adjust with 2005 inflation, it is much worse than Andrew.

The 1929 flood was really bad because heavy rain fell in April and May, just about a couple weeks apart. Think about that happening today. It would be much worse than Allison in terms of damage and lives loss. It could be one of the worst disasters in US history.
