Al Gore fucking GUARANTEED that by now the coastal cities would be underwater.And your point is correct. Precipitation events like Harvey are far more rare than storm surges. But when they occur, the wall would be an impediment to drainage. Still, that wall is a wise thing to build, and will give the area additional time to figure out what measures are necessary as the sea levels rise over the next decades.
