Land Use Classifications

Knox County

Planned Residential (PR)

The regulations established in this zone are intended to provide optional methods of land development which encourage more imaginative solutions to environmental design problems. Residential areas thus established would be characterized by a unified building and site development program, open space for recreation and provision for commercial, religious, educational, and cultural facilities which are integrated with the total project by unified architectural and open space treatment.

HDR

High Density Residential
HDR

This land use is primarily characterized by apartment and/or mixed use development at densities greater than 24 dwelling units per acre.
Location Criteria
  • On major collector and arterial streets, adjacent to regional shopping and major office districts (office sites allowing four or more stories); these sites must be identified in sector or small area plans

HP

Hillside Protection
HP

This classification is used to identify hillsides, ridges and similar features that have a slope of 15 percent or more. Open space, recreation land or very low density housing (one dwelling unit per two acres) is recommended for slopes exceeding 25 percent. For slopes of 15 to 25 percent, housing densities should not exceed 2 dus/ac). Office uses may also be considered. Building height should not exceed 35 feet.
Location Criteria
  • Hillsides greater than 15 percent slope

LDR

Low Density Residential
LDR

This type of land use is primarily residential in character at densities of less than six (6) dwelling units per acre (city) and less than five (5) dwelling units per acre (county). Conventional post-1950 residential development (i.e. large-lot, low-density subdivisions) and attached condominiums are typical.
Location Criteria
  • Land served by water and sewer utilities and by collector roads
  • Slopes less than 25 percent

MDR

Medium Density Residential
MDR

Such land uses are primarily residential at densities from 6 to 24 dwelling units per acre (city) and 5 to 12 dwelling units per acre (county). Attached houses, including townhouses and apartments are typical. Mobile home parks are another form of this land use.
Location Criteria
  • Near community activity centers, including uses such as schools and colleges, parks, and community commercial/office nodes
  • As transitional areas between commercial development and low density residential neighborhoods
  • Site with less than 15 percent slopes
  • Along or near corridors that are served by or proposed to be served by transit, with densities proposed to be above 12 dwelling units per acre and to be served by sidewalks

MDR/O

Medium Density Residential / Office
MDR/O

Office and medium residential uses typically have similar development characteristics: scale of buildings, areas devoted to parking, yard spaces and location requirements (on arterials/ collectors).

These uses provide a buffer to low density residential areas, particularly when located adjacent to an arterial/collector or as a transition between commercial uses and a neighborhood.
Location Criteria
  • Near community activity centers, including uses such as schools and colleges, parks, and community commercial/office nodes
  • As transitional areas between commercial development and low density residential neighborhoods
  • Site with less than 15 percent slopes
  • Along or near corridors that are served by or proposed to be served by transit, with densities proposed to be above 12 dwelling units per acre and to be served by sidewalks

MU-RC

Mixed Use Regional Center
MU-RC

These are envisioned to be highest intensity mixed use centers. These districts should be served by sidewalk and transit systems and be located on a major arterial, adjacent to an Interstate highway or adjacent to downtown.

Downtown Knoxville?s Central Business District is a regional mixed use center.
Location Criteria
  • Flat site (generally less than 10 percent slopes)
  • Currently served by or planned to be served by sidewalks
  • The location does not include auto and truck- oriented uses such as industrial, strip commercial and warehouse/distribution uses unless the proposal calls for a redevelopment of such areas
  • On a major arterial, adjacent to an interstate highway or adjacent to downtown

MU-UC

Mixed Use Urban Corridor
MU-UC

Several street corridors within the city have potential for redevelopment with a mix of retail, restaurants, office and residential uses.

Commercial cores should be created at points (nodes) along these corridors, allowing a vertical mix of uses (for example, shops at ground level and apartments above); such nodes should not be more than four blocks long.
Location Criteria
  • Corridors should have sidewalks, transit services, street trees and related beautification
  • Capable of sustaining on-street parking along corridor or along side streets
