Later this month, the U.S. Army Corps of Engineers will recommend a multi-billion-dollar plan to help protect the Texas coast — the Houston area in particular — from hurricanes. When it will become a reality, however, is anyone’s guess.
The more than 200-year-old agency — in partnership with the Texas General Land Office — embarked on the largest study in its history in 2014 to determine how best to guard the Bayou City and other coastal communities from devastating storm surge.
Four years later, the agency has devised four proposals for the Houston area; it will announce which one it thinks is best on Oct. 26 and open a 75-day public comment period, according to Kelly Burks-Copes, a project manager at the Army Corps’ Galveston District.
The plans are distinctly different — one of them has an alternate variation — but all include a mixture of new levees, improvements to existing levees and seawalls and the installation of so-called “navigation” gates, which would be closed ahead of storms to protect densely populated areas southeast of Houston and the city’s port — home to the largest refining and petrochemical complex in the nation, which saw significant flooding during Hurricane Harvey — from the deadly swells generated by a hurricane’s strong winds. That storm surge can result in major flooding even before a storm makes landfall.
One of the plans calls for the construction of a 17-foot-high levee along the entirety of Galveston Island, which is about 27 miles long, and the barrier island to its north, Bolivar Peninsula — a concept that has been dubbed the “coastal spine.” Another includes a levee through most of Bolivar but not Galveston. Others call for the construction of new levees and floodwalls further inland. All the plans include the installation of navigation gates in various places and the construction of a so-called “ring levee” around the heart of the Galveston that would protect the island’s backside from retreating storm surge.
Here’s the study. The four proposals are:
Alternative A: Coastal Barrier/Nonstructural System, with or without a Galveston Ring Levee
Alternative B: Coastal Barrier (Modified)
Alternative C: Mid Bay Barrier
Alternative D: Upper Bay Barrier/Nonstructural System, with or without a Bay Rim
Click over to read what they mean. There are also nine Ecosystem Restoration proposals to go along with this. As the story notes, both the original “Ike Dike” idea, proposed in 2008, and the more recent SSPEED Centennial Gate, or maybe the even more recent mid-bay gate, I’m honestly not sure, are in the running. Like I said, go see for yourself what’s on the table. One winner will emerge, and we’ll get a public comment period after that, and then we just need to solve the trivial problem of funding. No big deal, right?
