TX - $31B “Ike Dike” hurricane protection project approved by U.S. Senate

(GALVESTON, TX) - The U.S. Senate voted to authorize the U.S. Army Corps of Engineers to begin planning for a massive coastal barrier project in Galveston Bay meant to protect against hurricanes’ storm surge. Funding is not yet secured.

The U.S. Senate on Thursday approved a bill that would authorize federal agencies to plan for an estimated $31 billion project intended to protect the Texas coast from hurricanes.

Hundreds of millions of dollars have already gone into studying the idea to build a system of concrete gate barriers at the mouth of Galveston Bay. Nicknamed for the destructive hurricane that hit Galveston Island in 2008, the so-called Ike Dike could be the largest civil engineering project in U.S. history.

The project is included the Water Resources Development Act, which contains various federal water, coast and flooding projects that require congressional approval to move forward, but does not allocate funds. The bill passed with 93 yes votes in the Senate on Thursday; only Sen. Mike Braun, R-Indiana, voted no.

The U.S. House passed its version of the act in June. The legislation will go back to the House for the two chambers to iron out differences before sending it to President Joe Biden for approval. But the Texas coastal spine project is authorized in both versions.

Republican Sen. John Cornyn said the project brings Texas “one step closer” to ensuring the state’s coast will be as “prepared as possible” for future hurricanes.

“Protecting the Texas coast from devastating hurricanes is a top priority when it comes to preserving the livelihoods of Texans and ensuring the massive amount of international trade that relies on our state can resume after a storm,” Cornyn said in a statement.

The Ike Dike is part of the larger Texas Coastal Project, which was proposed to protect the state’s shoreline against hurricane storm surge and rising sea levels. It includes a series of other coastal infrastructure and environmental projects, from artificial barriers to beach and dune restoration.

The Ike Dike gate project alone would account for at least $16 billion and require 18 years to build, according to U.S. Army Corps of Engineers estimates. The gates would span a nearly 2-mile gap from the island to Bolivar Peninsula.

The act doesn’t include funding for the Ike Dike and the rest of the Texas coast projects, which will require a separate request to Congress from the U.S. Army Corps of Engineers. Congress is expected to fund the project in smaller appropriations rather than all at once.
