For others to understand, Charleston is like New Orleans: it is built below sea level. With time and construction, the land has been elevated, but the ground underneath is still wet and high tides (good salt water) can wreck havoc on driving. I would love to look at those undercarriages six months from now.
I lived on the corner of King and George St. while at CofC, back in the days when AC's Bar and Grille (same vibe as the Mos Eisley Cantina from Star Wars) and other bars were located below Calhoun St. Flooding was bad, but nothing compared to East Bay and Wentworth. My ex wife even made the local news today, speaking about how much it had flooded in the market area.
Good luck to all in the wake of Issac's path. Let's hope $10billion plus of Army Corps Engineered Levies can stand up to the brunt of Issac, inflicting only minimal damage.
