One winning entry in an architecture competition to reimagine the Astrodome proposes a Houston Ark.
The designers behind the entry, HiWorks with Erica Goranson, write an amusing story to go along with the images from a post-apocolyptic perspective 150 years in the future:
“In 2046, when storm waters from the relatively weak Tropical Storm Rick breached the trillion-dollar [Ike Memorial Dike] and surged up the Ship Channel, Houston knew it had only a few years left to prepare … It was not a dramatic surge of a storm that moved the Houston Ark off its moorings. Instead it was the slow and incremental rise of the Gulf.” Eventually the ark floats across what was the state of Florida.
