SEC. 6. FEATURES.

   The exterior architectural features of the Kearny-Belden District are as follows:

   (a)   Massing and Composition. The Kearny Street facades are elaborate designs, while the Belden Street facades are utilitarian in character. The treatment of the facades reflects the differing character of the streets. Kearny Street is a major pedestrian and vehicular corridor, and a prime shopping street. For the most part, the Kearny Street facades are two- or three-part vertical compositions consisting either of a base and a shaft, or a base, a shaft and a capital. Belden Street is a narrow alley, originally created to allow access to the interior of the block. The facades on Belden Street are largely unornamented, perhaps with a corbelled cornice or a decorative tile roof. The compositions are simple one-part structures from one to four stories high. There are a few small stucco buildings, probably built as warehouses. These designs are successful in maintaining the street enclosure, largely because the narrow widths of the streets do not demand a high building or one with multiple parts.

      In addition, the Kearny Street facades are often divided into bays expressing the structure. This was accomplished through fenestration, structural articulation or other detailing which serves to break the facade into discrete segments.

      Both the scale and height of the buildings in the District are extremely small, a result of the lot and street patterns. The lot depth is generally under 60 feet, and half the lots have frontages on Kearny and Belden Streets. As a consequence of the limited size of lots, most of the buildings are limited to four stories or less. A number of the buildings are only one story high.

      Without exception, the buildings in the Kearny-Belden Conservation District are built to the front property line and occupy the entire site.

   (b)   Scale. The buildings are of small scale, created by the buildings' elaborate detailing and low height. A major influence on scale is the degree to which the total facade plane is broken into smaller parts which relate to human scale. Window and door openings are relatively small, creating large wall areas, which are frequently heavily ornamented. The bay width is generally from 15 feet to 20 feet. Heights generally range from one to four stories on lots 20 feet to 30 feet wide, although a few taller and wider buildings exist. As noted above, the wider frontages are often broken up by articulation of the facade, making the buildings appear narrower. On the Kearny Street facades, the base is generally delineated from the rest of the building, giving the district an intimate scale at the street.

   (c)   Materials and Colors. Buildings are either clad in masonry over a supporting structure, or are constructed of masonry with load-bearing walls. The cladding materials include brick, terra cotta, and stucco. Materials have rough surface treatments, especially those located on the alleys, reflecting the building's utilitarian nature. Wood, metal, and metal panels are not commonly used facade materials in the District, although painted wood and metal are sometimes used for window sash and ornament.

      The materials are generally colored of light or medium earth tones, including cream, buff, yellow and red. Individual buildings generally use a few different tones of one color, highlighting the ornament. Dark or intense colors are not commonly used.

      The Belden Street facades are simply treated wall surfaces, with little expression of weight or mass from wall articulation. The small unit of the brick creates a textured facade, and reduces the scale of the undifferentiated facades.

   (d)   Detailing and Ornamentation. The Kearny Street frontages are not constructed in a single style, but with ornament drawn from a variety of historical, primarily Classical, sources. Popular details include arches, columns, pilasters, projecting bracketed cornices, multiple belt-courses, elaborate lintels, and pediments. Details were used to relate buildings to their neighbors by repeating and varying the ornament used in the surrounding structures.

      The Belden Street frontages are unadorned, except for slight corbelled cornices at the upper levels or false tile roofs on the stucco buildings.

SEC. 7. STANDARDS AND GUIDELINES FOR REVIEW OF NEW CONSTRUCTION AND CERTAIN ALTERATIONS.

   (a)   Standards. All construction of new buildings and all major alterations, which are subject to the provisions of Sections 1110, 1111 through 1111.6 and 1113, shall be compatible with the District in general with respect to the building's composition and massing, scale, materials and colors, and detailing and ornamentation, including those features described in Section 6 of this Appendix. Emphasis shall be placed on compatibility with those buildings in the area in which the new or altered building is located. In the case of major alterations, only those building characteristics that are affected by the proposed alteration shall be considered in assessing compatibility. Signs on buildings in Conservation Districts are subject to the provisions of Section 1111.7.

      The foregoing standards do not require, or even encourage, new buildings to imitate the styles of the past. Rather, they require the new to be compatible with the old. The determination of compatibility shall be made in accordance with the provisions of Section 309.

   (b)   Guidelines. The guidelines in this subsection are to be used in assessing compatibility.

      (1)   Composition and Massing. New construction should maintain the character of the District by relating to the prevailing height, mass, proportions, rhythm and composition of existing historic buildings.

         The height and massing of new buildings should not alter the traditional scale of existing buildings, streets and open spaces. On the Kearny Street, the existing streetwall height should be maintained. An appropriate streetwall height is established by reference to the prevailing height of the buildings on the block and especially that of adjacent buildings. If the adjacent buildings are of a significantly different height than the rest of the buildings on the block, then the prevailing height of buildings on the block should be used as a guide. A setback at the streetwall height can permit additional height above the setback without breaking the continuity of the street wall. On Belden Street, where the street wall is less well defined, greater latitude in height may be allowed. The height limit of 50 feet should be used as a guide to the appropriate height.

         Existing buildings are built to the property or street line. This pattern should not be broken since it could damage the continuity of building rhythms and the definition of streets.

         The standard proportions for new buildings should be established by the prevailing streetwall height and width of lots. Maintenance of the existing lot pattern and building proportions should be encouraged. In cases where lot assembly does occur, the facades of new buildings should be broken into discrete elements that relate to prevailing building proportions. The use of smaller bays can be used to relate the proportions of a new building with those of historic buildings.

         The design of the new structure should reflect the characteristics of the blockfront. Kearny Street facades should repeat the prevailing pattern of two- and three-part vertical compositions, although low buildings could use a one-part vertical division. A base element is necessary to define the pedestrian environment. Belden Street facades should be simply treated, with a cornice or other definition at the roof level.

      (2)   Scale. The existing scale of the immediate area and the Conservation District should be maintained. This can be accomplished in a variety of ways, including a consistent use of size and complexity of detailing with regard to surrounding buildings, continuance of existing bay widths, maintenance of an existing streetwall height, and incorporation of a base element (of similar height) to maintain the pedestrian environment. Large wall surfaces, which increase a building's scale, should be broken up through the use of detailing and textural variation to reduce the scale.

         Existing fenestration (windows, entrances) rhythms and proportions which have been established by lot width or bay width should be repeated in new structures. The spacing and size of window openings should follow the sequence set by historic structures. Large glass areas should be broken up by mullions so that the scale of glazed areas is compatible with that of neighboring buildings. Casement and double-hung windows should be used where possible.

      (3)   Materials and Colors. The use of like materials can relate two buildings of obviously different eras and styles. Similarly, the use of materials that appear similar (such as substituting concrete for terra cotta) can link two disparate structures, or harmonize the appearance of a new structure with the architectural character of a Conservation District. The preferred surface materials for this District are brick, or concrete (simulated to look like terra cotta or stucco). The texture of surfaces can be treated in a manner so as to emphasize the bearing function of the material, as is done in rustication on historic buildings. In addition, in some cases it may be appropriate to leave the surface roughly dressed, emphasizing the utilitarian character of the interior frontages.

         Traditional light colors should be used in order to blend in with the character of the Kearny Street facades. Dissimilar buildings may be made more compatible by using similar or harmonious colors, and to a lesser extent, by using similar textures. Belden Street facades should use red brick and stucco-like materials.

      (4)   Detailing and Ornamentation. A new building should relate to the surrounding area by picking up elements from surrounding buildings and repeating them or developing them for new purposes. An ornamental detail can be taken from an adjacent building and used in a new building to relate the latter to the surrounding area. Alternately, similarly shaped forms can be used without directly copying historical ornament. The new structure should incorporate prevailing cornice lines or belt courses and may use a modern vernacular instead of that of the original model.
