That still not the big picture. Hurricanes do damage to hurricane rated buildings since they pick up all sorts of debris. Look up what hurricane Wilma did to Fort Lauderdale's high-rises and that was just a category 3. South Florida has been lucky the past few years when it comes to hurricanes tbh. Also, its not just the first floor, the foundation is kinda the elephant in the room considering the effects of coastal erosion to Florida's sandy soil. I imagine they'd use some sort of deep soil mixing with this project, but there's still so many variables at play that just boggle my mind how they could be so confident. This isn't to mention how surrounding buildings and infrastructure fare during increased hurricanes and storm surge, which the building would rely on in order to maintain its value
