Hurricane Ike was a category 4 that traveled nearly directly over Houston in 2008. (It wasn't a category four when it passed over, since, like all major storms, they weaken as they move inland.)

Burying lines, especially in historic areas, is incredibly expensive and not necessarily a panacea either, although it helps. Is it worth it?
Realistically, for the millions upon millions of people that live in the greater Houston MSA (and of course except for those who rely on power for healthcare equipment, who really need to invest in a small generator or get to a shelter), it's far more cost effective to simply deal with power outages every decade or two.
During Ike, large parts of Houston, especially to the northeast, were literally underwater, so power wouldn't have helped anyway. The number of utility crews lined up along highways from other states, even from thousands of miles away, in the immediate aftermath of Ike is both inspiring and enlightening, especially when you recognize that they were going into a disaster zone, likely without a nice hotel to go back to or even running water after working a 12 hour shift.
So, no, it's just part of living near the coast in a hurricane-prone area. If you don't like it, move somewhere else.
