CLARENCE, N.Y. — Uniland Development Co. has acquired a $14.5 million interest in Mountain Development Corp.’s Eastern Hills Mall in Clarence, about 20 miles east of Buffalo. The Buffalo News, citing documents filed in the Erie County clerk’s office, reported the amount of the sale. The enclosed, 86-acre shopping mall will be redeveloped by the joint venture partners into Western New York’s first open-air, multi-use town center. During the redevelopment, the mall will remain open. No changes will be made to the mall until a master plan is complete in two to three years. Current tenants at the mall include Bon Ton, JCPenney, Orvis Sporting Goods and Sears. Brian Whitmer, Andrew Merin, David Bernhaut, Gary Gabriel, Seth Pollack, Joyce MacKnight, Ben Borruso and Kubby Tischler of Cushman & Wakefield represented Mountain Development Corp. in the transaction.
