Researchers Propose $7B Galveston Bay Park to Shield Houston Ship Channel From Storms

At Rice University’s SSPEED Center, researchers are advocating for a $7 billion initiative to create a 10,000-acre barrier island in Galveston Bay. They argue that this project could protect Houston’s petrochemical and shipping sectors from devastating hurricane impacts.

The Galveston Bay Park Plan, revealed in May, aims to dredge clay soil to create a levee reaching heights of up to 25 feet along the Houston Ship Channel. The system is set to feature navigation openings and will ultimately incorporate a storm-surge gate. 

“My greatest worry is that if those sectors are struck by a significant storm without sufficient safeguards, we could face the most catastrophic environmental crisis in the history of the United States,” stated Jim Blackburn, an environmental attorney spearheading the initiative.

The proposal emerges as the area anticipates the $57 billion Coastal Texas Project, a U.S. Army Corps of Engineers endeavor that may require two decades to complete. Economists from SSPEED suggest that their proposal could act as a quicker safety net. 

Blake Eskew, chief economic consultant for the project, shared, “The possible economic and environmental repercussions from such storms are immense, making it wise to plan at an elevated standard.”

The implications are significant. The Houston Ship Channel features an impressive array of 6,000 above-ground storage tanks, collectively containing a staggering 10 billion gallons of various chemicals. 

According to Eskew, the expense of replacing petrochemical and refining facilities located in high-risk zones could reach $50 billion. Authorities report that a mid-bay barrier has the potential to reduce storm surge by 50% from a Category 4 hurricane affecting Clear Lake, Texas City, and the ship channel.

Advocates present the initiative as essential. “Our mission is to safeguard lives, property, and economic vitality, and innovative solutions like this could be crucial,” stated Coalter Baker, executive director of the Gulf Coast Protection District. League City Mayor Nick Long expressed strong support for initiatives aimed at mitigating storm surge effects, stating, “We fully support any project that reduces the impact of storm surge and look forward to learning more details.”

However, some doubt the practicality of the large mid-bay barrier. “I’m not sure if a project like [this] has ever been built,” stated Joanie Steinhaus, ocean program director of Turtle Island Restoration Network. Bob Stokes, president of the Galveston Bay Foundation, cautioned that “any massive infrastructure project … could very easily wind up affecting salinity.” It may ultimately affect the flow. It represents an enormous impact.

The economic outlook continues to be ambiguous. A report released in May increased the estimated cost from $4.5 billion to $7 billion, taking into account 20% in unexpected expenses and 30% in permitting fees. 

Currently, there is no funding available. However, Eskew is optimistic about obtaining $3 billion via the Coastal Texas Project, with Texas contributing 35% and local communities potentially covering the remainder. Some voices in the debate suggest that sectors ought to shoulder a greater share of the expenses. “What is the rationale behind the general public and our tax dollars being tasked with providing protection for them?” Steinhaus inquired.

Despite receiving approval, construction is unlikely to commence until post-2031, coinciding with the widening of the ship channel by Port Houston. This could delay completion by an additional ten years. “What we’re discussing for Galveston Bay … we’re discussing the largest engineering project globally,” Blackburn concluded.
