Under a new ordinance, TND is a development option anywhere within the City of Knoxville, Tennessee. City planners developed the ordinance during the building of Mechanicsville Commons, a Hope VI redevelopment of a public housing project. It applies to tracts of largely undeveloped land with a minimum size of 10 acres in or adjacent to pre-1940 neighborhoods, and 20 acres in other areas. The maximum housing density is eight units per acre, and the total ground floor area of the commercial and offices uses cannot exceed five percent of the TND, unless the Planning Commission deems that the area can support more day-to-day services. Every TND application must be accompanied by a pattern book and guidelines for building height, use of materials, and design of porches, windows, and doors.
