Tennessee Code Title 7. Consolidated Governments and Local Governmental Functions and Entities § 7-84-612

Any inner-city redevelopment district created by a municipality may embrace two (2) or more separate property areas. Each district shall be of such size and form as to include all properties that, in the judgment of the governing body, shall be benefited by the improvements and services that are proposed to be made and provided in or for such district. The jurisdiction of a municipality to make and provide, finance and levy assessments for the cost of any improvements and services within a district shall not be impaired by a lack of commonness, unity or singleness of the location, purpose or character of the improvements or services, or by the fact that any one (1) or more of the properties included in the district are subsequently determined not to be benefited by such improvement or improvements, or by a particular portion of the improvement or improvements, and is not assessed for such improvement or improvements.
