A River at Risk: The True Cost of Wilmington’s Port Expansion
Why a proposed Wilmington Port expansion would be a $1.3 billion mistake
The Cape Fear River is a lifeline for the 500,000 people who drink from it, for the fisheries and marshes that define coastal North Carolina, and for the migratory birds and threatened species that depend on the barrier islands and tidal creeks at its mouth. As the North Carolina Coastal Federation outlines, the U.S. Army Corps of Engineers is proposing to fundamentally alter that lifeline with a more than $1.3 billion plan to deepen and widen the channel leading to the Wilmington Port. The Moore Charitable Foundation and its many North Carolina grantees stand against the proposal.
The proposal — which would deepen the river channel from 42 to 47 feet for approximately 28 miles and widen significant stretches of the channel by several hundred feet — promises marginal economic gain at extraordinary environmental cost. The project’s projected benefit-to-cost ratio is an anemic 1.3. It’s not worth the effort, especially because any benefits would flow primarily to large corporations saving marginally on shipping costs, not to Wilmington-area residents.
The threats are real and wide-ranging. Deeper channels amplify tidal forces, accelerating flooding in communities already battered by hurricanes. Dredging would destroy over 1,000 acres of wetlands. Among what’s at risk: the West Bank conservation corridor on the Cape Fear River, where more than 19,500 acres have been permanently protected since 1998 through decades of private conservation worth millions and more than $16 million in public funds.
As Jesica Blake of the North Carolina Coastal Land Trust puts it, “That kind of ecological continuity, built painstakingly over 25 years through private generosity and public investment alike, is what makes any threat to this corridor so consequential. Once a conservation corridor is fragmented and degraded, the compounding benefits it provides are extraordinarily difficult to restore.”
The Southern Environmental Law Center warned the Corps in formal comments filed on behalf of a dozen organizations, “Any decision to alter [the Cape Fear River] must be weighed with care, transparency, and accountability.” The Corps’ own environmental review, SELC argues and many have agreed with, falls far short of that standard.
Audubon North Carolina documented in its formal comments that the expansion promises “irreparable harm while proposing scant and uncertain offsets” to bird nesting habitat on the Lower Cape Fear River — home to over 16,000 breeding pairs of coastal waterbirds, representing roughly 30 percent of North Carolina’s nesting coastal waterbird population.
And then there is the contamination. The Cape Fear watershed has been ground zero for PFAS pollution for decades, with GenX chemicals saturating the region’s water supply since at least 2017. Dredging 35 million cubic yards of river sediment risks unleashing that toxic legacy — yet the Corps initially proposed not even testing the material. PFAS found in the blood of local alligators already has been linked to immune issues, an alarming indicator of ecosystem-wide exposure. Spreading contaminated dredge spoil onto beaches and habitat restoration sites could compound the harm for generations.
North Carolina’s own Division of Coastal Management found that the project would have “significant adverse impacts,” a formal consistency objection that should give every decision-maker pause. Add the numerous towns and local government bodies that have expressed concerns or objections, and there is a clear, growing movement against this unnecessary and expensive taxpayer-funded project.
The North Carolina Coastal Land Trust, North Carolina Coastal Federation, SELC, Audubon North Carolina, Cape Fear River Watch, and many others have made clear that economic development and environmental protection are not irreconcilable but that this project, as designed, fails both tests.
The decisions made about the Port of Wilmington will shape the North Carolina coast for generations. We must get this right.
