Harris County Commissioners Approve Two Projects That Could Benefit Humble-Kingwood Area

Harris County Commissioners Court unanimously approved two items on today’s agenda that could eventually benefit the Humble/Kingwood Area.

  • #60 Recommendation to execute a Partnership Agreement with TXDoT for preliminary engineering and environmental review for a railroad grade separation on Hamblen Road, from Loop 494 to Laurel Springs Lane.
  • #83 Authorization to negotiate an interlocal agreement for a partnership project with the SJRA, Humble, and five utility districts for a feasibility study and conceptual design on the Spring Creek Watershed Flood Control Reservoirs.

Consideration of the projects was originally scheduled for last Friday. But visits by President Biden and Governor Abbott delayed that part of the meeting until today.

More About the Projects

The first item will formally establish a partnership with TXDoT to study the feasibility of rerouting Hamblen Road north to meet up with a bridge over US59 at Sorters-McClellan Road. The project, is key to managing traffic in Harris County’s new 90-acre Precinct 4 Edgewater Park. The preliminary engineering study will also look at building a bridge over the Union Pacific Railroad tracks. The latter is important because UP has announced its intention to start running longer trains. If one derailed, it could theoretically block every exit to Kingwood.

The second item will further explore the feasibility of one or more Flood Control Reservoirs upstream from the Lake Houston Area along Spring Creek. This could reduce the amount of inbound water during future floods. In that regard, it is worth noting that the amount of water coming down Spring Creek during Harvey almost exactly equaled the amount of the SJRA’s release from Lake Conroe. Thus, such a project could partially offset future Lake Conroe releases during floods.

Next Steps

Neither of these projects involves approval to begin construction. They simply will study the feasibility, locations, costs, and nature of construction. Commissioners would have to approve construction after studying the results of the studies. But first the engineering department and Flood Control District must solicit bidders to conduct the studies.
