One of the overlooked aspects of the Houston flooding is that some of it was caused by actions of the US Army Corps of Engineers!
The Corps has built many man made reservoirs over the years to control flooding. Although made to control flooding, they quickly become scenic places to build houses to enjoy recreation and scenic views.
