I have added a new photo taken from one of the NOAA sat photos of my neighborhood post-Katrina. My street is the slender crescent at the top of the photo and our house stood at the very end. What looks like roof is actually some flooring. No walls are left standing on the house.
If you look at the street, you will see a couple of houses with intact roofs. I think these are hurricane roofs. The one large one in about the center of the street with a bluish roof has concrete pilings. I think the rest of them were on wooden pilings but my memory is not always the greatest when under stress - lol!
It is not always evident when photographed from above but as you move back from our house along the street toward the beginning, the houses are still there. They may have some major damage but essentially, they are standing. I find this significant as when you move toward the head of the street, you get some protection from other houses and trees across the small canals that spread throughout our neighborhood. On our end of the street, it's wide open to the Jordan River, the marsh, and the upper Bay.
Wind or water, what do you think? I will be looking forward to your comments.
