floodplain
A floodplain is the tract of land where a river woos settlers with promises of fertility before walloping them with floods. It is nature's merciless marketer, extolling rich soil while omitting disclaimers about seasonal inundation. Developers stake their dreams on bountiful earth, only to feed those same plans to the fire of flood insurance. In the end, water merely reclaims what it never truly surrendered.
