KINGSPORT — The Model City is taking the next step toward redeveloping the remainder of the old General Shale property. Consultants are recommending that Kingsport build a multipurpose outdoor venue on the site, while marketing 25 adjacent acres for residential development. The next step is a $150,000 contract for additional geotechnical work on the property, along with a deeper economic analysis of the proposed venue. During its regular meeting Tuesday night, the Board of Mayor and Aldermen voted 6-1 to approve the contract.
