Today, the site consists of two open sand mines on Route 49, three miles east of the municipal building. The land is mostly forested, with some water at the bottom of the mines, but Eastern Concrete Materials, a subsidiary of Texas-based U.S. Concrete, was seeking approval from the board to combine both properties and greatly expand the operation. The company hopes to extract 25.2 million cubic yards of material from 256 acres of the 396-acre tract over the next 30-plus years, depending on the market.
