No. If I still lived in Houston if I were in one of those areas, I would have left before the storm.
Anyone who needs to be told when and where to evacuate is going to be a problem no matter what the mayor does, and where he sends them.
Tell me what in Houston is a flood prone area.
Is it the million dollar gated community four miles from me that has water up to the second floor?
The only obvious danger zone is the Brazos. And the Brazos went so high over its banks that the limited evacuation you would have done, would have been meaningless.
The reservoirs have never breached their banks in 60 years. Both did with devastating consequences. Is that a flood-prone area?
