A. Standards for the Designation of a Landmark Site, Local Historic District or Thematic Designation: The proposed landmark site, local historic district, or thematic designation shall be evaluated according to the following:
1. Significance in local, regional, state or national history, architecture, engineering or culture, associated with at least one of the following:
a. Events that have made significant contribution to the important patterns of history, or
b. Lives of persons significant in the history of the city, region, state, or nation, or
c. The distinctive characteristics of a type, period of significance, or method of construction; or the work of a notable architect or master craftsman, or
d. Information important in the understanding of the prehistory or history of Salt Lake City; and
2. Historic integrity in terms of location, design, setting, materials, workmanship, feeling and association as defined in Section 21A.62.040. When analyzing historic integrity, the collective historic value of the buildings and structures in a local historic district taken together may be greater than the historic value of each individual building or structure in a district.
3. The proposed landmark site, local historic district or thematic designation is listed, or is eligible to be listed on the National Register of Historic Places;
4. The proposed designation contains notable examples of elements of the city's history, development patterns or architecture not typically found in other local historic districts within Salt Lake City;
5. The designation is generally consistent with adopted planning policies; and
6. The designation would be in the overall public interest.
B. Factors to Consider: The following factors may be considered by the historic landmark commission and the city council to help determine whether the proposed designation of a landmark site, local historic district or thematic designation meets the criteria listed above:
1. Sites are of an age that allows insight into whether a property is sufficiently important in the overall history of the community as identified in one or more periods of significance in a historic survey report. Typically, this is at least fifty (50) years but could be less if the property has exceptional importance.
2. Whether the proposed local historic district or thematic designation contains examples of elements of the city's history, development patterns and/or architecture that may not already be protected by other local historic districts within the city.
3. Whether designation of the proposed local historic district or thematic designation would add important knowledge that advances the understanding of the city's history, development patterns and/or architecture.
4. Whether approximately seventy five percent (75%) of the structures within the proposed boundaries are rated as contributing structures by the most recent applicable historic survey and those relate to identified significance and periods of significance.
C. Boundaries of a Proposed Landmark Site: When applying the evaluation criteria in Subsection 21A.51.040.A, the boundaries of a landmark site shall be drawn to ensure that historical associations, that best enhance the integrity of the site comprise the boundaries.
D. Boundaries of a Proposed Local Historic District: When applying the evaluation criteria in Subsection 21A.51.040.A, the boundaries shall be drawn to ensure the local historic district:
1. Contains a significant density of documented sites, buildings, structures or features rated as contributing structures in a recent historic survey;
2. Coincides with documented historic boundaries such as early roadways, canals, subdivision plats or property lines;
3. Coincides with logical physical or manmade features and reflect recognized neighborhood boundaries; and
4. Contains noncontributing resources or vacant land only where necessary to create appropriate boundaries to meet the criteria in Subsections 21A.51.040.A and 21A.51.040.D.
E. Boundaries of a Proposed Thematic Designation: When applying the evaluation criteria of this section, the boundaries shall be drawn to ensure the thematic designation contains a collection of sites, buildings, structures, or features that are associated by historical, architectural, or aesthetic characteristics and contribute to the historic preservation goals of Salt Lake City by protecting historical, architectural, or aesthetic interest or value.
