The latest figure is 68% higher than an earlier estimate of $34 billion, and it’s unclear when — or whether — Congress will appropriate the money to build the massive system of gates intended to protect the Houston region from storm surge.

The far-right congressman from Friendswood still backs the conservative push to lower spending, but worries bipartisan Texas projects have been impacted.

President Joe Biden signed a large defense bill on Friday that includes a water bill that directs the Army Corps of Engineers on major infrastructure projects to improve navigation and protect against storms worsened by climate change.

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. House voted to authorize the U.S. Army Corps of Engineers to begin planning for the massive coastal barrier project in Galveston Bay, but funding is not yet secured. The largest civil engineering project in U.S. history would permanently alter the Texas coast.

The Ike Dike is a coastal barrier that, when completed, would protect the Houston-Galveston region including Galveston Bay from hurricane storm surge. Now the close call has renewed a debate about whether the Houston area should build a massive and expensive barrier to protect against storm surge. Galveston Bay is healthy, and fish and other animals thrive there because water circulates in and out of the gulf, said Bob Stokes, president of the Galveston Bay Foundation environmental group. “No hurricane storm surge barrier will ever protect us from 150 mph winds. No hurricane storm surge barrier will ever protect us from rain,” Stokes said.
