  2. Intent and Applicability

    The Traditional Neighborhood Form District (TNFD) is intended to promote the development and redevelopment of neighborhoods in a manner consistent and compatible with the distinct site and community design elements of a traditional neighborhood. TNFD design standards are also intended to promote the establishment of a mixture of uses that effectively integrate retail, office, insitutional, and other non-residential uses within traditional neighborhoods in a manner that provides high quality and convenient service to residents while protecting the character of the neighborhood.

    The provisions of this section are intended to encourage that new development within the TNFD is consistent with a traditional neighborhood pattern and form of development, promoting as applicable:
    1. Appropriate and compatible integration of residential, civic, commercial and office uses that promote close-to-home shopping and service opportunities;
    2. Parks and open space resources convenient to neighborhood residents;
    3. Alternative modes of travel including public transit amenities;
    4. Compatible infill development whether residential or commercial;
    5. Inclusive housing opportunities; and
    6. High quality design of individual sites.
    The TNFD standards may be applied to both existing neighborhoods and proposals to create new neighborhoods. The standards address both the internal site design elements of a development (e.g., building location, design, and orientation) and the relationship of the development to the surrounding community context (e.g., relationship to the adjacent street/sidewalk network).
  3. Lot Dimensional Standards
    1. Infill Standards – Non-Residential and Mixed Use Development
      Where 50% or more of the linear street frontage within the same or opposing block face is occupied by principal structures exhibiting site design consistent with a traditional development pattern, the following additional standards shall app
      1. Front Setback/Build-to Line and Street Sideyards. Where there are highly uniform setback/build-to lines (at least 50% of the structures on the block face have setbacks that vary by 10% or less), the setback/build-to line for the new structure shall be the average setback of existing structures in the block face. Where there is more than 10% variation in setbacks within the block face, the setback/build-to line shall fall within the range of the setbacks of the nearest constructed properties. Exception: Corner buildings with non-residential and mixed uses shall use Table 5.2.2.
      2. Building Height. The maximum building height shall be 45 feet or 3.5 stories unless an adjacent building is taller in which case the proposed structure may be as tall as the tallest adjacent building.
      3. Sites that do not qualify as Infill Sites shall be developed in accordance with Table 5.2.2.
    2. Infill Standards – Residential Development

      See Chapter 5 Part 4 Residential Site Design Standards for traditional form districts (Section 5.4.1)
    Dimensional standards for development that is not in an Infill Context are listed in Table 5.2.2 below. Lots created after the effective date of this Land Development Code shall meet the minimum area requirements of Table 5.2.2. Residential lots having less area than required and legally created prior to the adoption of these regulations may be occupied by one dwelling unit. For lot dimensional standards for Conservation Subdivisions see Table 7.11.1.
