A casino that could be one of the top employers in Carson City can build the city’s biggest hotel and tallest building as part of its resort project, the planning commission said Wednesday. Las Vegas-based Golden Gaming Inc. got permission to build the USD 100 million Sierra Gold on 4.5 acres at the corner of Highway 50 East and the Carson City freeway. It will have a 100,000-square-foot casino, an eight-story, 220-room hotel and stand 118 feet tall, passing the 110-foot Ormsby House.
