I would heartily encourage you to find that home in the areas you're talking about. Lovely area!
Contrary to MSM belief we Texans do remember lessons from previous serious hurricanes. My family evacuated Houston in 1961 and we all remember what it was like when we returned home. Grandparents were in Gilchrist - right across the bay from Galveston at that time. My grandfather had the contract for dredging Rollover Pass. I remember what it looked like when we went back there and I was only 3.
My dad, my uncles and lots of cousins have worked for my grand-dad's company. He's done a lot of seawall work on the coast. I guess that explains why my family works with emergency helps when things happen - but heck, our friends and neighbors here 250 miles from the coast are all on the same page too. We don't forget that preparation is the best remedy.
