Storm surge could top seawall and flood city

FORT WORTH, Texas - (KRT) - Galveston's massive seawall offers little protection to the thousands of Texas homes and businesses sitting behind it if Hurricane Rita slams into the barrier island.
If Rita makes landfall as a Category 5 storm, it could produce a storm surge at least as high as 22 feet, which would easily overtop Galveston's 17-foot-high, 10-mile-long seawall, experts say.
Perhaps worse, the back of the island isn't protected by the seawall and sits at a much lower elevation, meaning that it would flood as the Gulf of Mexico rises.
"It will inundate the entire city," said Don Van Nieuwenhuise, a geologist at the University of Houston. "The whole island will be under water."
