I mean, the next one is coming whether we’re ready or not. We just don’t know when it will be here.
Though the storm ultimately tracked east, sparing Houston, the problem remains: The region is disastrously unready to handle any of the three main threats of an intense hurricane: a high surge, damaging winds and — even three years after Hurricane Harvey — flooding.
While Harvey’s devastating stall over the Houston area has resulted in billions of dollars of investment in flood control infrastructure and new regulations, Laura reminded the region of what a different kind of storm could do.
In its wake, leaders have made impassioned pleas about preparing for when — not if — that storm does arrive. Most notably, they have ramped up calls for federal funding on a so-called “coastal spine,” a system of levees, gates and dunes first proposed after Hurricane Ike in 2008, to protect the region from a storm surge.
Those plans, though, remain mired in the slog of the federal approval process. The kind of political will and cohesion needed to fast-track such infrastructure typically only forms after disasters, not before.
There are signs the region has reached an inflection point on the need to protect against that threat. A growing consensus among local officials around the effects of climate change has shifted the public policy debate to figuring out which infrastructure projects will help stave off its worst effects, and at what cost.
The proposed coastal spine, a 71-mile-long barrier system to protect the southeast Texas coast, has received the most attention since it was taken up by the Army Corps of Engineers in October 2018.
The plan is an outgrowth of the “Ike Dike” concept first pitched more than a decade ago by William Merrell, a professor of marine sciences at Texas A&M University at Galveston. It includes a series of gates that stretch the two-mile length of Bolivar Road, twin rows of 14-foot-high sand dunes across Galveston Island and Bolivar Peninsula, a ring levee around Galveston’s city center and investments in ecosystem restoration.
The price tag has been put at $23 billion to $32 billion, with the dunes and sea gate at the ship channel alone costing up to $18 billion of that. It is in the midst of a five-year design and study process and is on track to be sent to Congress for final approval in May 2021.
“Quite frankly, we need it yesterday,” Houston Mayor Sylvester Turner said last week. “We’re running out of lives, so to speak.”
Even on the most optimistic timeline, the coastal barrier is 10 to 15 years from becoming a reality. With the Houston-Galveston region a perennial target during the Atlantic hurricane season, there is a growing urgency to find a more expedient, cheaper solution.
The Galveston Bay Park Plan, first proposed by the Rice University’s Severe Storm Prediction, Education & Evacuation from Disasters (SSPEED) Center in 2015, includes similar protection features as the coastal spine, but adds a mid-bay barrier island system with a 25-foot wall that would protect the industrial complexes and densely populated areas in the west and northwest sections of Galveston Bay.
Jim Blackburn, an environmental attorney and co-director of the SSPEED Center, says the plan could provide vital protection a lot sooner than the coastal spine, but that it also could complement that barrier. He estimates that if allowed to use dredging spoils from the planned widening of the Houston Ship Channel to build the barrier islands, the project could be completed by 2027 at a fraction of the cost of the coastal spine — an estimated $5 billion to $7 billion.
“You have a coastal defense and that’s your first line of defense and then you come in with your in-bay defense, that is really the one that can protect against your bigger storms,” Blackburn said. “It’s very much almost like thinking in a military sense of how do you defend against an enemy invasion?”
See here and here for some background. I’m of the opinion that we just need to start building something, and that the price tag is a mirage, because the federal government can absolutely afford this. What we can’t afford is to sit around on our asses until the devastating storm we’ve been warned about for years comes and wipes our unprepared selves right off the map.
