 Texas City is mostly surrounded by a levee system that was built in the early 1960s following the devastating floods from Hurricane Carla in 1961.Together with pump stations containing several Archimedes' screws located at various places throughout the northeast periphery of the city adjoining Galveston, Dollar Bay, and Moses Lake, the levee and pump station system may well have saved the city from wholesale devastation at the hands of Ike's powerful tidal surge.Damage in the city was largely limited to that caused by Ike's powerful winds and heavy rains.
