West Fork Dredging

City Mobilizing for More West Fork Dredging

Mobilization for the next phase of San Jacinto West Fork dredging is underway. The City of Houston and its contractor DRC (a subsidiary of Callan Marine) are already staging equipment in two places on the West Fork.

The program, funded by FEMA, will remove an estimated 800,000 cubic yards of silt and sediment between the original location of the West Fork Mouth Bar and FM1960. The contractor will use primarily hydraulic dredging and the program will take approximately two years, according to District E City Council Member Fred Flickinger.

West Fork Dredging Project Dates Back to Dave Martin Era

Flickinger credits his predecessor, former Council Member Dave Martin, and Chief Recovery Officer Stephen Costello’s tireless efforts in protesting the initial amount proposed for dredging by FEMA back in 2019. FEMA’s initial proposal, based on a four-page, table-top study produced by the Army Corps, called for dredging 283,000 cubic yards.

Martin strongly disagreed with the Corps’ report and appealed it while the City produced its own 94-page technical report. It showed a much higher volume deposited by Harvey. Remember: Harvey funds could not be used to address sediment deposited before Harvey. The City report produced by Tetra Tech relied extensively on core samples. Tetra Tech proved that Harvey laid down the sand in the mouth bar and that the dredging volume should be closer to a million cubic yards.

In August 2020, FEMA and the Corps finally concurred with the City, after extensive discussions and a massive assist from U.S. Representative Dan Crenshaw. Crenshaw and others had been pushing FEMA for years for the additional dredging.

Current Status

The new West Fork dredging program should be ready to go within weeks. DRC is currently bringing in the equipment that they will need.

DRC plans to use primarily hydraulic dredging. They will attack the area between where the mouth bar was (south of Scenic Shores in Kings Point) and the FM1960 Bridge. See map below.

DRC is also starting to stockpile mechanical dredging equipment such as these pontoons on Berry Madden’s property south of River Grove Park (top center).

This is good news. The new West Fork dredging will help ensure that water doesn’t back up like it did before. It’s not a guarantee against flooding. Dredging is only one part of a multi-faceted mitigation program that also includes more upstream detention and new floodgates on the Lake Houston dam. More news on those topics to follow.
