Yep, I just heard from a friend/coworker down there. Some of those underpasses on 610 are downright deadly when it rains big. People who don't realize it drive right into them at freeways speeds and disappear. I recall being there in 92 when it flooded bad and the only thing that wasn't were the canals on the southwest side of town, along N/S Braeswood blvd.

Houston's tough to make weather safe. If you build to average terrain, you're gonna flood, if you build to high ground, you're gonna get hit by all the lightning in the area.

I like a place where I can go underground and not get flooded out like a gopher.
