Wal-Mart, the world’s largest retailer, was thwarted in its quest to lease at Related Companies’ retail center in East New York, Brooklyn. But sources tell the Observer that the company is looking at some vacant land that would support a 300,000-square-foot store near the Queens-Brooklyn border. One possibility: Ridgewood, near the rapidly gentrifying Brooklyn neighborhood of Bushwick, according to Douglas Elliman broker Faith Hope Consolo. Meanwhile, a Wal-Mart spokesman told the salmon paper that there’s “nothing new regarding Walmart in NYC,” but said that New Yorkers want to shop at the store and travel to suburban locations to do so. The company’s most recent quarterly earnings missed estimates.
