On the first point, you're correct about Harvey. Several neighborhoods were built in the basin of a flood plain. And lesser examples of such poor planning and drainage are all over Houston. But sometimes it really is storms that stall over the city dropping rain for three days. To the second point, yeah... My family tried to evac Rita (2005) and got 5 miles in three hours. Turned around, and the storm missed us. Three years later, my parents stayed for "cat 2" Ike and were trapped in the attic for 12 hours because Galveston Bay had come five feet up our house.
