Houses able to float being developed to address flooding

This is hardly the first attempt to develop land vulnerable to flooding. There are 20,000 fully-floating and can-float homes already built in the Netherlands.
Back in the mid-1870s, Sacramento, California raised the level of its downtown by approximately 10 feet (3 meters) to eliminate devastating flooding. They built reinforced brick walls on downtown streets, and filled the resulting street walls with dirt. Building owners either raising their building slowly with the use of numerous screw jacks, or buried the ground floor. Thus the previous first floors of buildings became the basements.
Of course these solutions are no help if it is just the value of your house and mortgage that is "underwater".
It's called a "houseboat".
As someone envisioned FEMA's new housing specs:
