Coastal challengesTexas might spend up to $20 billion to protect Houston from hurricanes. Rice University says it can do it for a fraction of that.

A government plan to guard the Houston-Galveston region from deadly storm surge could cost as much as $20 billion and isn’t expected to become reality for at least 15 years. Rice University says it has a plan that could be completed faster for a fraction of the cost.

For about a decade, two of Texas’ top universities have pushed dueling plans to protect the Houston-Galveston region from hurricanes.

A concept championed by Texas A&M University at Galveston appears to be winning out as the federal and state governments pursue a plan similar to one proposed by A&M oceanographer Bill Merrell in early 2009, months after Hurricane Ike smashed ashore at Galveston Island.

But that project by the U.S. Army Corps of Engineers and the Texas General Land Office, which calls for the installation of beachfront sand dunes and massive storm surge barrier gates, won’t become reality for at least 15 years — and probably much longer. That leaves plenty of time for a worst-case hurricane to devastate the densely populated, highly industrialized region — a reality that’s coming into sharper focus as sea levels rise and the ocean warms.

The so-called coastal barrier system also carries a significant price tag — as much as $20 billion — and a significant part of the system may guard against only a modest, 100-year storm.

In the meantime, Rice University is pushing a plan that it says could become a reality faster and more cheaply than the coastal barrier system. While the “Galveston Bay Park Plan” isn’t designed to protect as much land as the coastal barrier system, the chief spokesperson for the university’s Severe Storm Prediction, Education and Evacuation from Disasters (SSPEED) Center says it would offer a significantly higher level of protection than the coastal barrier system for the most populated and industrialized areas in Houston and Galveston.

The park plan, conceived in 2015, calls for the use of clay dredged from the Houston Ship Channel, where a $1 billion deepening and widening project is in the works to accommodate more and larger ships, to create a 25-foot-tall levee along the shipping lane, which is the nation’s busiest. Additional dredged material would be piled behind it to form parkland. The dike would connect to an existing levee at Texas City, which would be raised to 25 feet from 17 feet.
