A network of eight massive storm water tunnels that drain upstream of and into the Houston Ship Channel could be the key to alleviating flooding in Harris County, flood control engineers announced this week. The scheme looks at how storm water management has traditionally worked here and re-imagines, at a steep cost, how the system could be drastically expanded.
The Harris County Flood Control District, formed in 1937, has long dealt with flooding in two ways: Engineers built channels to move water away and dug detention ponds to store it temporarily. But those methods are increasingly challenging to implement, they say, because so much of the area has been developed. Texas prairie is covered with asphalt, concrete and buildings.
Climate change is also broadening the scale of what the region faces: Rains are likely to be more intense. Hurricanes are likely to be stronger.
And so Flood Control staff for several years studied how tunnels might work to lessen the storm water buildup that accompanies heavy rainfall. On Thursday, the agency released its findings in a detailed report that explains why a $30-billion, 130-mile network of tunnels could be worth the investment. The team says it has more research to do before committing to the idea fully, but the concept checks out so far.
“We have determined that a large-diameter underground tunnel system would significantly reduce flood risk and the number of instances of flooding,” said Scott Elmer, assistant director of operations for the flood control district. “And, as we consider expanding our current flood damage reduction toolkit by investing in a tunnel system, we would gain an additional tool to use in the many areas of our county where the land is densely populated.”
A question ahead is whether people here will support it. Residents and advocates recently called for consideration of a tunnel below Buffalo Bayou instead of a vehemently-opposed federal proposal to dig the bayou deeper and wider. The flood control district’s proposal, of course, takes the tunnel idea much further, marking a shift toward massive, costly solutions that could protect Houston better from worsening weather. It raises familiar issues of risk and environmental harm. It highlights the same complexities of how planners prioritize who to help.

Anyone else wonder how much of that $30 Billion would find its way into the pockets of the mayor's former law partners?

A complete boondoggle, without question.
