Council approves annexation for Vulcan Materials overburden extension; company promises no new utilities or production

The Concord City Council on Jan. 8 unanimously adopted an annexation ordinance adding roughly 13.4 acres to city limits for property owned by CalMat Corporation, Vulcan Lands Inc. and private owners.

Suzanne Todd, a land-use attorney representing Vulcan Materials Company, and Denise Hallett, Vulcan’s manager of community and government relations, told council the annexation covers three contiguous parcels and is intended to allow an overburden-storage extension for Cabarrus Quarry. Todd said all property owners signed the annexation application and the company will seek rezoning and a special-use permit limiting the site to overburden storage.

"The proposed overburden extension will not increase production or market demand and will actually keep thousands of trucks off the road by keeping the storage on-site," Hallett said.

The presenters said the annexation will not require the city to provide water, sewer, electricity, trash pickup or build new roads and that the area would be added to Vulcan’s existing mining permit and regulated by state and federal agencies. Vulcan said the overburden is expected to be filled over a 10–15 year period and ultimately returned to a vegetated natural area.

Council discussion was brief; the mayor called for a motion to adopt the annexation ordinance effective Jan. 8, 2026, and the motion passed by voice vote.

The annexation is the first step in Vulcan’s larger plan, which the company said could ultimately be part of a 142-acre overburden extension. The company also said it will apply for a special-use permit that, by its terms, would restrict future uses of the annexed acreage to overburden storage only.

Next steps noted by staff: the rezoning application will go before the planning commission in February, followed by any required special-use-permit review and the addition of the parcel to Vulcan’s mining permit.
