Like an empty stomach, talks of a downtown grocery store have been rumbling as the number of residents in the city's core continues to grow. But before a large grocery store chain — or an independent grocer, for that matter — would locate downtown, it must consider a variety of factors from parking availability to customer base. "From a downtown standpoint, we haven't been prodded by anyone to try and find a location," said Budd Cullom of Knoxville's CHM Development, which specializes in grocery stores and retail. "That doesn't mean any of these (grocers) might not be looking." A 30,000-square-foot grocery store space is included in renderings for the proposed Old City baseball park complex, but no tenant has been announced.
