Ike Dike

The Ike Dike is a proposed coastal barrier that, when completed, would protect the Galveston Bay in Texas, United States. The project would be a dramatic enhancement of the existing Galveston Seawall, complete with floodgates, which would protect more of Galveston, the Bolivar Peninsula, the Galveston Bay Area, and Houston. The barrier would extend across Galveston Island and the Bolivar Peninsula and would provide a barrier against all Gulf surges into the bay. The project is primarily the suggestion of Dr. Bill Merrell of Texas A&M University at Galveston. The Ike Dike would be able to withstand ~10,000 year storms.

The proposal is, as the name suggests, motivated by the damage caused by Hurricane Ike in 2008 (as well as the disastrous 1900 Galveston Hurricane). Storm surges from Hurricane Ike caused severe damage to Galveston and the Bolivar Peninsula and caused significant damage to other areas around the bay. Fortunately the damage to critical industries was minimal and most heavy industry returned to normal quickly. Still, Ike was not nearly as destructive as meteorologists predict a future hurricane will eventually be.

Proponents argue that there is a national security concern that must be addressed. The Houston area (particularly the Bay Area) is home to the largest and most important concentration of petroleum refining and petrochemical processing plants in the United States, and most of these plants are on the coast or on the ship channel. Additionally the Port of Houston is the second-busiest port in the nation. The economic damage to the United States, not to mention Texas, in the event of a catastrophic impact on the coast would be nationally serious. Indeed, some researchers have argued that had Ike tracked a few miles further southwest it could have sidelined 40% of U.S. jet-fuel production, not to mention serious setbacks to the production of gasoline and other chemicals
