What Don't They Get?

It seems pretty weird but reportedly it is planed to build more than 11,400 new homes on flood plains in England (https://www.theguardian.com/environment/2020/feb/23/more-than-11000-homes-to-be-built-on-land-at-high-risk-of-flooding). These have a very high risk of flooding (with a lowered ability to be insurance) and are generally within or close to areas already suffering from repeated flooding. I know that people want homes but preferably not underwater!
