In determining the recommendations to be made
to the Borough Council concerning the issuance of a certificate of
appropriateness, HARB shall consider only those matters that are pertinent
to the preservation of the historical and/or architectural aspect
and nature of the building, site, area, or district, certified to
have historical significance, including the following:
A. Broad historical values representing the cultural,
political, economic, or social history of the Borough.
B. The relationship of the building or structure to historic
personages or events.
C. Significant architectural types representative of
a certain historical period and a style or method of construction.
D. The effect of the proposed change upon the general
historical and architectural nature of the district.
E. The appropriateness of the exterior architectural
features which can be seen from a public way.
F. The general design, arrangement, texture, and material
of the building or structure and the relation of such factors to similar
features of buildings or structures in the district. Consideration
shall be given but not be limited to the following:
(1) Proportion of building's front facades: preserving
the relationship between the width of the front of the building and
the height of the front of the building.
(2) Proportion of openings within the building: preserving
the relationship of width to height of windows and doors.
(3) Rhythms of solids to voids in the front facade: preserving
the relationship between a recurrent alteration of strong and weak
architectural elements thereby maintaining a rhythm of solids to voids.
(4) Rhythm of spacing of buildings on streets: preserving
the existing rhythm of recurrent or repeated building masses to spaces
between each building.
(5) Rhythm of entrance and/or porch projections: preserving
the existing rhythm of entrance or porch projections to maintain a
pedestrian scale.
(6) Relationship of materials: preserving the predominant
materials of the district such as brick, stone, stucco, wood siding,
or other material.
(7) Relationship of textures: preserving the predominant
textures of the district which may be smooth, such as wood siding,
or rough, such as masonry.
(8) Relationship of architectural details: preserving
character-defining features of buildings, such as architectural details,
including but not limited to cornices, lintels, arches, quoins, balustrades
and iron work, chimneys, etc.
(9) Relationship of roof shapes: preserving compatible
roof shapes such as gable, mansard, hip, flat, gambrel, and/or other
kinds of roof shapes.
(10)
Walls of continuity: preserving physical elements
which comprise streetscapes such as brick walls, wrought iron fences,
building facades or combinations of these which form visual continuity
and cohesiveness along the street.
(11)
Directional expression of front elevation: preserving
the orientation of structural shapes, plan of openings and architectural
detail that reflect a predominantly vertical, or horizontal character
to the building facade.
(12)
Scale: preserving the scale of the built environment
created by the size of units of construction and architectural detail
that relate to the size of persons. In addition, preserving building
mass and its relationship to open space.
