The Army Corps has completed the original scope of its West Fork Emergency Dredging Project. Great Lakes, the prime contractor, finished its portion of the job in mid-April. This week, Callan Marine, the subcontractor, finished its portion of the dredging.
Subcontractor Callan Marine Now Demobilizing
Callan has already begun demobilizing. So far, the company has unhooked its dredge from its pipeline and is removing its booster pumps and other equipment from the river. Callan should have all of its equipment back at the command site dock by this weekend.
Yesterday, Keith Jordan, a resident of Kings Lake Estates, greeted the news joyfully. “Hallelujah! It’s simply amazing how quiet it is tonight. It’s been a long 8 months!” Jordan had a booster pump anchored behind his home the entire time and complained several times to the Corps about noise.
Callan operated the blue dredge that worked the area downstream from the West Lake Houston Parkway bridge since approximately January.
Mouth Bar Contract Extension Ahead of Schedule
In other news, Great Lakes is far ahead of schedule on a contract extension. The extension is a separate mission assignment from FEMA to the Corps for slightly more than $17 million. It involves dredging 500,000 cubic yards of sediment from the mouth bar. The Corps originally thought the extension would take until January, 2020. However, at the current rate, Great Lakes could finish next month – in less than half the time predicted.
Five-hundred thousand cubic yards will barely scratch the surface of what needs to be removed and may not even be sufficient to cut a channel through the mouth bar area, thus leaving most of the mouth bar intact. It is unclear at this time what the plans are to restore conveyance through this area of the West Fork.
Current Dredging Photos from Carolyn Daniel
A reader, Carolyn Daniel, sent me several pictures taken earlier this week from the window of an airplane as it descended into Bush Intercontinental Airport. They show the Great Lakes Dredge south of the mouth bar. The company also removed vegetation from leading edge of the mouth bar itself. Perhaps they hoped that river currents could help erode the bar which contains far more than 500,000 cubic yards.
These images illustrate the enormity of the task ahead and the need to be ruthlessly efficient with resources and time.
Tomorrow, I will look at some of the challenges ahead, and some of the obstacles to restoring conveyance.
