Port Houston will undertake its own study of portions of a potential Project 12 to deepen the Houston Ship Channel, CEO Charlie Jenkins announced at the Port Commission meeting on Oct. 21 — a move that keeps the region’s marquee infrastructure expansion on schedule as terminal capacity heads toward a projected 2033 ceiling.
The port-led work will proceed under Section 203 of the Water Resources Development Act of 1986, which allows a non-federal interest to conduct a feasibility study and submit it directly to the Secretary of the Army for review. The port-led study runs in parallel with a traditional feasibility study being carried out with the U.S. Army Corps of Engineers on improvements to the broader Houston Ship Channel and Galveston Bay system. Port Houston and the Corps held a federal interest determination meeting the week before the commission session, kicking off a 45-day process that will produce a recommendation on the Project 12 scope of study, according to Baird Maritime’s DredgeWire coverage.
The stakes for the local economy are substantial. The Houston Ship Channel complex — the port’s eight public terminals plus private facilities along the channel — supports well over a million Texas jobs in petrochemicals, steel, containerized trade and logistics, and every foot of additional depth expands the vessel classes that can call here fully loaded. Port Houston handled more than 4.3 million twenty-foot equivalent units in 2025, and loaded imports rose 5% year to date through September, evidence that post-tariff trade rerouting continues to favor Gulf gateways.
Capacity planning is moving on a second track as well. The port is evaluating options for the additional container capacity it projects the region will need over the next decade, including an expansion north of Barbours Cut Container Terminal onto Spilman Island. Port Houston cautions that remains one of multiple options and would require a formal Final Investment Decision by the commission before advancing. A Corps permit notice describes a terminal of roughly 318 acres with two berthing slips capable of supporting ultra large container vessels and about 3,200 feet of pile-supported wharf. The port forecasts existing container terminals will hit their throughput limit by 2033, with new expansion capacity available by 2036; the Corps expects to publish the environmental impact statement in spring 2028.
For Houston’s business community, the timeline math is the point. A vessel already transiting today’s channel pays a draft penalty; deeper water means fewer lightering operations, more direct calls and lower landed costs for importers, while exporters of resin, machinery and agricultural products gain reliability when draft restrictions hit other ports. Resin exporters along the channel, the region’s largest manufactured export, have lobbied for successive expansions since the original Project 11 program added width and depth that was completed in recent years.
Funding remains the open question. Section 203 studies shift early design and analysis costs onto the local sponsor — in this case the port itself — in exchange for control of pace and scope, with construction cost-share negotiations to follow. Port leadership has consistently argued the channel’s federal economic contribution justifies continuing investment, and the commission has reserved funds in prior budget cycles for Project 11 closeout and engineering on the next phase.
Neither the port nor the Corps has published updated cost estimates for Project 12, and the 45-day scope recommendation will shape what the eventual feasibility study covers. Business groups tracking the project say the next milestone to watch is the completion of the federal interest determination, which formally frames the study boundaries for the deepening program.
