Tsunami from Asteroid Impacts

One of the people featured in the last episode of "Doomsday Preppers" was afraid that a comet would cause a tsunami and that he would have to be 1500 feet above sea level in order to escape the damage caused by a comet impact. So, I did a little googling, and I found a fabulous and detailed report on the potential danger from tsunami caused by asteroid or comet impact.

In order to save you from a ton of reading, it seems that the worst-case tsunami from asteroid is 230m estimated deepwater wave height (above sea level) tsunami at a point 100km from impact of an asteroid with a 2km diameter. That's about 750 feet above sea level if you are a typical American who can't do rough metric conversions in your head.
