The Harris County Flood Control District is set to receive a $320,000 federal grant to study the feasibility of constructing deep underground tunnels to move stormwater to the Houston Ship Channel without overburdening the area’s bayous.
The grant, from the U.S. Economic Development Administration, will fund a four-month investigation to determine whether such tunnels would be a practical and cost-effective addition to the county’s long-term flood protection strategy. The flood control district has begun work on scores of projects funded by the $2.5 billion flood bond approved last summer, though none to date include underground tunnels.
“The study is basically to look at our ground conditions, including our groundwater table, and compare that to existing technology in the tunnel industry to see if there’s a match,” said Russ Poppe, executive director of the flood control district. “If that’s true, then we can start looking at costs, routes and opportunities we can potentially pursue.”
Jim Blackburn, co-director of the Severe Storm Prediction, Education, and Evacuation from Disasters Center at Rice University, raised no objection to studying the tunnel idea but said he worries that pursuing the proposal could become a boondoggle that siphons money from other, more urgent priorities.
“It’s one of those big dream projects that may take us away from much more reasonable short-term projects,” Blackburn said. “I doubt the feasibility of it.”
See here and here for the background. Looks like we were originally going to get that study last year, but for whatever the reason it didn’t happen. If it’s going to happen this time, it will be after the next Commissioners Court meeting on Tuesday, when they will vote on approving the study and ponying up $80K in matching funds. I’ll check back with it afterward.
