E.
Location Criteria for Limited Building Types. Buildings indicated as limited application in Table 6-2, Non-residential Building Standards, (□) shall only be permitted in the following locations within the applicable zoning districts, unless more specifically located through a planned district.
1.
In the C-O, C-1, C-2, C-3 and BP zoning districts, the limited building types should only be permitted to front on streets or through access drives that promote a high level of pedestrian activity based on the Pedestrian/Mixed-Use, Avenue and Boulevard street types. Additionally, in any area where the City has invested in or documented plans to invest in improved streetscapes, mixed-use building types and street-front or terrace frontage types may be required.
2.
In the DT, MU-NC, MU-CC, and MU R/EC zoning districts, the non-residential building types should only be used on secondary blocks or streets, through access drives, or similar locations that are otherwise removed from the walkable streets or arterial streets. In these circumstances, these buildings should be used for a key anchor or support uses that are important to the vitality of the district but cannot easily conform to more compact, walkable building formats. Alternatively, where these buildings are located on pedestrian-oriented streets, they should be buffered by liner buildings and smaller mixed-use or commercial buildings that better address the streetscape or hide large parking areas.
3.
The residential building types (row house and small, medium, and large apartments) should be located on blocks and streets that create transitions between the mixed-use or commercial areas and neighborhoods.
(Ord. No. 2405, §§ 15—18, 1-3-2023)
A.
Design Objective. A variety of open space types shapes the character of a place and creates unique identities for different places. The following design objectives shall be use in applying the open space types and design standards in this section.
1.
Coordinate site design with the larger open and civic space system and public realm design of the area.
2.
Use open space as an organizing element for development, creating focal points for buildings or groups of buildings, and creating transitions between distinct building sites or different places.
3.
Design a hierarchy of gateways, gathering places, parks, buffers and natural features, integrated with streets, through access ways and pedestrian circulation routes.
4.
Use landscape, furnishings, fixtures, art, planters and other elements of common spaces to complement buildings, coordinate buildings and sites within an area, and distinguish the unique character of different places.
5.
Preserve natural features that can serve as amenities for development, maintain views to and from important outside spaces, or provide important connecting corridors.
B.
Required Open Space Each building type shall provide the open space specified in Table 6-3, Site Open Space Standards - Non-residential Buildings, within the site or project.
C.
Lot and Building Open Space Design. Lot open space required for each building type in Section 6.03.B. shall create a common or private amenity for the site and building in coordination with the lot and building standards. Buildings and lots shall be arranged to create usable outdoor spaces based on the following:
1.
Required open space shall be designed according to the types specified in Section 3.02.C.
2.
The selected types of open spaces shall be based on the context of the area and the natural amenities of the site, but in general, the more compact and formal gathering spaces are most appropriate for commercial and mixed-use areas (the Green, Square, Plaza/Courtyard, Patio, Pedestrian Passage, or Enhanced Streetscape).
3.
The requirement for open space for mixed-use buildings with residential units, up to 50% of the required space may be made up of private spaces only accessible to the unit, such as balconies or courtyards, provided each private space is at least 80 square feet and at least 8 feet in any direction.
4.
Projects with residential components may credit any public or common open space meeting the design requirements and within the distance specified in table 6-3 provided:
a.
The space is public or remains open to the public; or
b.
If private or common space, the lot applying the credit has proven that it has access to the space through ownership or other agreement, and the space is otherwise dedicated and reserved from future development.
5.
Open spaces meeting this standard may serve multiple site design requirements of this code, including buffers, screening, stormwater or formal open space, provided the essential design objectives and functions for each requirement are met and do not compromise other design objectives and functions.
D.
Alternative Design. For the design standards in this Section 6.03, if the full extent of the design standard cannot be met, the Director may approve an alternative design that equally or better meets the design objectives or enhances another design standard of this section.
(Ord. No. 2405, § 19, 1-3-2023)
A.
Design Objectives. The design of lot frontages establishes the relationship of buildings and lots to the streetscape. The following design objectives shall be used in applying the frontage types and design standards in this section.
1.
Enhance the image of the City by coordinating streetscape investment with private lot and building investment.
2.
Orient all buildings and lots to the public street, or to common open spaces that serve as an extension of the streetscape and public realm.
3.
Design frontages based on the context of the area, block and street, particularly using water-wise landscape and buffers to screen and separate sites from higher-volume/higher speed streets and using social spaces and human scale design in areas and on streets intended for more compact and walkable development.
4.
Coordinate development across multiple lots along block faces, considering access, parking, landscape and civic/open space design.
5.
Create transitions that allow a range of different building types to engage the streetscape in compatible ways along a block.
6.
Where contexts allow multiple frontage types, the frontages should be similar for all lots on the same block face or gradually transition to different types.
B.
Non-residential Frontage Types. The appropriate application of frontage types is based upon a combination of the character of the zoning district, the building type, and the streetscape design on which the development fronts. Table 6-4, Non-residential Frontage Types specifies the appropriate frontage type(s) for each street design type Specified in Section 3.02, but may allow limited applications of other types based on the context and specific street.
C.
Frontage Design Standards. Frontage types shall be designed according to the standards in Table 6-5, Non-residential Frontage Types and Design Standards.
1.
Front Building Line. All buildings shall establish a front building line within the range specified in Table 6-5. This required front building line shall modify any required front setback for the building type in Table 6-2 based on the appropriate frontage for the street and block.
2.
Required Extent of Front Building Line. All buildings shall occupy the minimum percentage specified at the front building line with:
a.
Front building facades meeting the design standards in Table 6-6, Non-residential Building Design; or
b.
Open spaces meeting the requirements of Section 6.03, Site Specific Open Space Design.
c.
Parking, driveways or other buffers and landscape may occupy the remainder of any unspecified portion of the frontage area.
3.
Driveway Widths. Driveway widths shall be limited as specified in table 6-5 to balance multi-modal site access and the integrity of the streetscape within the overall street network and block structure.
4.
Landscape. The remainder of the frontage between the streetscape and front building line shall include landscape and open space designs meeting Section 6.03, Site-Specific Open Space Design and Article 8, Landscape and Site Design Standards.
D.
Alternative Design. For the design standards in this Section 6.04, if the full extent of the design standard cannot be met, the Director may approve an alternative design that equally or better meets the design objectives or enhances another design standard of this section.
(Ord. No. 2405, § 20, 1-3-2023; Ord. No. 2438, §§ 6—8, 1-2-2024)
A.
Design Objectives. Building design refines the scale and form of buildings beyond the basic setback, height and lot coverage standards, by breaking down the volume into smaller-scale masses, and adding depth, texture, and variation to surfaces in a manner that specifically relate to the spaces around the building. The non-residential design standards have the following design objectives:
1.
Refine the scale, massing, and details of buildings to a greater degree the closer they are to the public realm and other publicly used spaces and based on the context, patterns, and design character of the area.
2.
Massing of buildings should create meaningful and human-scale outdoor spaces on the site, and relate the design of the buildings and facades to these spaces.
3.
Avoid contrived massing that serves only to call attention to the structure or attempts to make monumental or elaborate design out of simple structures.
4.
Locate doors and windows in a way that activates and creates connections to important exterior spaces.
5.
Relate buildings to adjacent development by mimicking similar scale, massing and proportions though step-backs and secondary masses that break up larger masses and reduce the volume and perceived size of larger buildings.
6.
Use materials, architectural details and ornamentation to add interest and uniqueness to buildings
7.
Windows, doors, trim and molding and other details and ornamentation should create depth and texture on wall planes. The depths of these details should be sufficient to take advantage of the sun and highlight changes in plane or materials by using light and creating shadow.
8.
Emphasize the quality and longevity of investments in the area with materials and colors that are attractive, durable, and have low maintenance requirements.
B.
Design Standards. Table 6-6, Non-residential Building Design, establishes design standards for massing and facade composition of all non-residential buildings. The standards apply to all facades that face streets, face through access lanes, or face open and civic spaces, based upon their setback from these spaces. They also apply to any building elevation with a side or rear within 100 feet of a public street (except for the entry feature requirement if it does not face this street). The subsections following the table specify the techniques used to meet the standards for each element in the table.
Figure 6-2 Primary Entrance Features
Primary entrance features activate building frontages and create human-scale points
of emphasis along the building facade. The frequency, rhythm and pattern of entrances
differ depending on the streetscape and frontage type, and determine the degree of
walkability or pedestrian orientation of particular areas.
1.
Primary Entrance Features. Primary public entrances shall be clearly defined on all front facades with at least three of the following elements and be located at intervals specified in Table 6-6, Non-residential Building Design:
a.
A single-story architectural emphasis such as raised parapets or gables, canopies, porticos, overhangs, pediments, or arches.
b.
Transoms and/or display windows that frame and emphasize the entry.
c.
Architectural details such as tile work and moldings, columns, pilasters or other similar material changes.
d.
Integral planters or wing walls associated with a recessed or projecting entry court or plaza that integrates more formal landscape and hardscape designs.
e.
Public art.
f.
For corner buildings, any entrance feature located on the corner may count to both sides, and may be considered located at 25' from each corner for the purpose of the required Primary Entry Feature intervals.
2.
Transparency. Buildings shall have the percentage of openings specified in Table 6-6, Non-residential Building Design, based on the following:
a.
Where expressed as a first story requirement the percentage shall be measured between 2 feet and 8 feet above the street level, or within 10 feet above the first floor elevation if the building is set back more than 20 feet from the street.
b.
Where expressed as an upper story requirement, the percentage shall be measured between the floor level and ceiling of each story.
c.
All first story windows required shall provide direct views to the building's interior or to a lit display area extending a minimum of 3 feet behind the window.
d.
For industrial and civic buildings setback more than 30 feet from the street, clerestory windows may meet the first or upper story window requirements.
Figure 6-3 Transparency.
Transparency requirements eliminate large expanses of blank walls and create physical
and perceptual connections to spaces around buildings. Meeting the requirements for
each story helps reduce the scale of larger buildings.
3.
Massing and Modulation. Larger facades shall be broken into smaller components by one or a combination of the following techniques at intervals specified in Table 6-6, Non-residential Building Design.
a.
Horizontal articulation and differentiation of the base, body and top of the building with material changes, belt courses or trim bands.
(1)
For buildings 3 stories or less, this can be a distinct foundation material to at least 2 feet above grade, the main façade, and an embellished roof structure, such as eaves and fascia for pitched roofs or cornices and parapets for flat roofs.
(2)
For buildings more than 3 stories, the first floor should be clearly differentiated from upper stories to establish the base.
(3)
Any belt course or trim band establishing this break shall use a use a material distinct from the primary material, be 18 to 48 inches wide, and off-set from the wall plane 6 to 24 inches.
Figure 6-4 Horizontal Articulation
Defining buildings with a distinct base, body and top can help reduce the scale of
larger buildings and can create relationships between adjacent buildings with dissimilar
scale.
b.
Vertical articulation and differentiation of structural components or interior breaks of the building with architectural columns or pilasters. Columns, pillars or pilaster shall meet the following:
(1)
Be regularly or symmetrically spaced and divide the elevation into at least 3 different components, but none greater than the intervals specified in Table 6-6, Non-residential Building Design;
(2)
Be at least 18 to 48 inches wide and 6 to 24 inches off-set from the wall plane;
(3)
Use a different arrangement, material or finish to distinguish it from the primary material of the elevation.
Figure 6-5 Vertical Articulation
Defining buildings with a distinct structural bay creates a finer grain of buildings,
both when viewed from a distance and when experienced on the streetscape. This is
particularly important for longer expanses of buildings and can help integrate larger
buildings and lots within a pattern of smaller buildings and lots.
c.
Variations in the wall plane with projections, balconies, cantilevers, step-backs structural focal points such as towers, or other variations from the main mass. Variations shall be associated with the entrance feature, different stories or secondary masses of the building.
d.
Any other blank wall areas in excess of the interval or areas specified in Table 6-6, Non-residential Building Design, shall be broken up by the patterns of windows and doors, ornamental architectural details or changes in materials that are consistent with the architectural style of the building.
4.
Materials. Use building materials with a texture and pattern that create visual interest and signify quality construction and detailing.
a.
The predominant surfaces on building walls shall be one of the primary materials listed in Table 6-7, Non-residential Building Materials.
b.
Synthetic alternates to the materials in Table 6-7 may be approved by the Director if manufacturer specifications and/or precedents for application demonstrate that it will perform equally or better than the principal materials in terms of maintenance, design and aesthetic goals.
c.
No more than 4 materials should be used, including the use of secondary and accent materials.
d.
Material changes and the use of primary and secondary materials from the approved material list shall emphasize different elements of the building, in association with the massing and modulation standards.
(1)
Where material changes are vertical (i.e. different materials stacked one above another), the transition between materials should include a belt course, trim band, sill, cap, frame, roof (if at ceiling height), or similar element to separate the two materials.
(2)
Where material changes are horizontal (i.e. different materials side-by-side) the transition between materials should occur at interior corners or at the trim line, architectural column or pilaster where the change is emphasizing different structural or massing components for a building.
e.
Facade colors shall be low reflectance, subtle, neutral or earth tone colors. The use of high-intensity colors, metallic colors, black or fluorescent colors is limited to accent areas.
5.
4-sided Design. All buildings shall incorporate 4-sided design, so that that no matter what view you have of the building, the design is not interrupted and all parts are perceived as a coordinated part of a unified whole. Specifically:
a.
All sides shall exhibit the same quality, continuity, and durability of design including the same primary and secondary materials, although more important sides can reflect priority in the allocation of these materials.
b.
All sides that are visible from streets, public spaces or active portions of adjacent sites shall have a similar level trim, accent material, details, and ornamentation, although the extent and details may be different to reflect the greater importance of certain areas closest to the public realm or with greater visibility, and parts not exposed to the public may be designed for utility.
C.
Downtown Frontages and Building Design. The building and frontage design standards for the DT district are modified on a block-specific basis according to Table 6-8, Downtown Building & Frontage Design, and the Map in Figure 6-6.
Block-Specific Frontages for DT zoning
Figure 6-6 DT Zoning District Frontage Map
D.
South 4thStreet Overlay District. The South 4 th Street Overlay district is established in Section 4.05.A. to allow a mix of uses within the South 4 th Street Corridor between Bridge Street and Bromley lane, to maintain the residential scale and character of the area, and to introduce small-scale commercial buildings at nodes and gateways. In general, the base zoning district standards shall apply except as modified in Table 6-9 with regard to permitted building types, frontage types and uses.
E.
Alternative Design. For the design standards in this Section 6.05, if the full extent of the design standard cannot be met, the Director may approve an alternative design that equally or better meets the design objectives or enhances another design standard of this section.

Any building or structure larger than this shall be treated as a second principal building and meet all lot and building design standards applicable to principal buildings.
g.
Accessory buildings shall not be located within an easement area.
4.
Detached Building—Civic Uses and Open Space. Accessory buildings for permitted institutional uses or public and common open spaces are permitted subject to the following:
a.
Setback. 30 feet from the front lot line or behind the front building line of the principal building, whichever is greater; 5 feet from the rear or side property line.
b.
Area. 5,000 square feet maximum.
c.
Height. 25', but 1' of additional height for each 2 feet of additional setback.
d.
Number. 1 per every 3 acres.
E.
Location Criteria for Limited Building Types. Buildings indicated as limited application in Table 6-2, Non-residential Building Standards, (□) shall only be permitted in the following locations within the applicable zoning districts, unless more specifically located through a planned district.
1.
In the C-O, C-1, C-2, C-3 and BP zoning districts, the limited building types should only be permitted to front on streets or through access drives that promote a high level of pedestrian activity based on the Pedestrian/Mixed-Use, Avenue and Boulevard street types. Additionally, in any area where the City has invested in or documented plans to invest in improved streetscapes, mixed-use building types and street-front or terrace frontage types may be required.
2.
In the DT, MU-NC, MU-CC, and MU R/EC zoning districts, the non-residential building types should only be used on secondary blocks or streets, through access drives, or similar locations that are otherwise removed from the walkable streets or arterial streets. In these circumstances, these buildings should be used for a key anchor or support uses that are important to the vitality of the district but cannot easily conform to more compact, walkable building formats. Alternatively, where these buildings are located on pedestrian-oriented streets, they should be buffered by liner buildings and smaller mixed-use or commercial buildings that better address the streetscape or hide large parking areas.
3.
The residential building types (row house and small, medium, and large apartments) should be located on blocks and streets that create transitions between the mixed-use or commercial areas and neighborhoods.
(Ord. No. 2405, §§ 15—18, 1-3-2023)
A.
Design Objective. A variety of open space types shapes the character of a place and creates unique identities for different places. The following design objectives shall be use in applying the open space types and design standards in this section.
1.
Coordinate site design with the larger open and civic space system and public realm design of the area.
2.
Use open space as an organizing element for development, creating focal points for buildings or groups of buildings, and creating transitions between distinct building sites or different places.
3.
Design a hierarchy of gateways, gathering places, parks, buffers and natural features, integrated with streets, through access ways and pedestrian circulation routes.
4.
Use landscape, furnishings, fixtures, art, planters and other elements of common spaces to complement buildings, coordinate buildings and sites within an area, and distinguish the unique character of different places.
5.
Preserve natural features that can serve as amenities for development, maintain views to and from important outside spaces, or provide important connecting corridors.
B.
Required Open Space Each building type shall provide the open space specified in Table 6-3, Site Open Space Standards - Non-residential Buildings, within the site or project.
C.
Lot and Building Open Space Design. Lot open space required for each building type in Section 6.03.B. shall create a common or private amenity for the site and building in coordination with the lot and building standards. Buildings and lots shall be arranged to create usable outdoor spaces based on the following:
1.
Required open space shall be designed according to the types specified in Section 3.02.C.
2.
The selected types of open spaces shall be based on the context of the area and the natural amenities of the site, but in general, the more compact and formal gathering spaces are most appropriate for commercial and mixed-use areas (the Green, Square, Plaza/Courtyard, Patio, Pedestrian Passage, or Enhanced Streetscape).
3.
The requirement for open space for mixed-use buildings with residential units, up to 50% of the required space may be made up of private spaces only accessible to the unit, such as balconies or courtyards, provided each private space is at least 80 square feet and at least 8 feet in any direction.
4.
Projects with residential components may credit any public or common open space meeting the design requirements and within the distance specified in table 6-3 provided:
a.
The space is public or remains open to the public; or
b.
If private or common space, the lot applying the credit has proven that it has access to the space through ownership or other agreement, and the space is otherwise dedicated and reserved from future development.
5.
Open spaces meeting this standard may serve multiple site design requirements of this code, including buffers, screening, stormwater or formal open space, provided the essential design objectives and functions for each requirement are met and do not compromise other design objectives and functions.
D.
Alternative Design. For the design standards in this Section 6.03, if the full extent of the design standard cannot be met, the Director may approve an alternative design that equally or better meets the design objectives or enhances another design standard of this section.
(Ord. No. 2405, § 19, 1-3-2023)
A.
Design Objectives. The design of lot frontages establishes the relationship of buildings and lots to the streetscape. The following design objectives shall be used in applying the frontage types and design standards in this section.
1.
Enhance the image of the City by coordinating streetscape investment with private lot and building investment.
2.
Orient all buildings and lots to the public street, or to common open spaces that serve as an extension of the streetscape and public realm.
3.
Design frontages based on the context of the area, block and street, particularly using water-wise landscape and buffers to screen and separate sites from higher-volume/higher speed streets and using social spaces and human scale design in areas and on streets intended for more compact and walkable development.
4.
Coordinate development across multiple lots along block faces, considering access, parking, landscape and civic/open space design.
5.
Create transitions that allow a range of different building types to engage the streetscape in compatible ways along a block.
6.
Where contexts allow multiple frontage types, the frontages should be similar for all lots on the same block face or gradually transition to different types.
B.
Non-residential Frontage Types. The appropriate application of frontage types is based upon a combination of the character of the zoning district, the building type, and the streetscape design on which the development fronts. Table 6-4, Non-residential Frontage Types specifies the appropriate frontage type(s) for each street design type Specified in Section 3.02, but may allow limited applications of other types based on the context and specific street.
C.
Frontage Design Standards. Frontage types shall be designed according to the standards in Table 6-5, Non-residential Frontage Types and Design Standards.
1.
Front Building Line. All buildings shall establish a front building line within the range specified in Table 6-5. This required front building line shall modify any required front setback for the building type in Table 6-2 based on the appropriate frontage for the street and block.
2.
Required Extent of Front Building Line. All buildings shall occupy the minimum percentage specified at the front building line with:
a.
Front building facades meeting the design standards in Table 6-6, Non-residential Building Design; or
b.
Open spaces meeting the requirements of Section 6.03, Site Specific Open Space Design.
c.
Parking, driveways or other buffers and landscape may occupy the remainder of any unspecified portion of the frontage area.
3.
Driveway Widths. Driveway widths shall be limited as specified in table 6-5 to balance multi-modal site access and the integrity of the streetscape within the overall street network and block structure.
4.
Landscape. The remainder of the frontage between the streetscape and front building line shall include landscape and open space designs meeting Section 6.03, Site-Specific Open Space Design and Article 8, Landscape and Site Design Standards.
D.
Alternative Design. For the design standards in this Section 6.04, if the full extent of the design standard cannot be met, the Director may approve an alternative design that equally or better meets the design objectives or enhances another design standard of this section.
(Ord. No. 2405, § 20, 1-3-2023; Ord. No. 2438, §§ 6—8, 1-2-2024)
A.
Design Objectives. Building design refines the scale and form of buildings beyond the basic setback, height and lot coverage standards, by breaking down the volume into smaller-scale masses, and adding depth, texture, and variation to surfaces in a manner that specifically relate to the spaces around the building. The non-residential design standards have the following design objectives:
1.
Refine the scale, massing, and details of buildings to a greater degree the closer they are to the public realm and other publicly used spaces and based on the context, patterns, and design character of the area.
2.
Massing of buildings should create meaningful and human-scale outdoor spaces on the site, and relate the design of the buildings and facades to these spaces.
3.
Avoid contrived massing that serves only to call attention to the structure or attempts to make monumental or elaborate design out of simple structures.
4.
Locate doors and windows in a way that activates and creates connections to important exterior spaces.
5.
Relate buildings to adjacent development by mimicking similar scale, massing and proportions though step-backs and secondary masses that break up larger masses and reduce the volume and perceived size of larger buildings.
6.
Use materials, architectural details and ornamentation to add interest and uniqueness to buildings
7.
Windows, doors, trim and molding and other details and ornamentation should create depth and texture on wall planes. The depths of these details should be sufficient to take advantage of the sun and highlight changes in plane or materials by using light and creating shadow.
8.
Emphasize the quality and longevity of investments in the area with materials and colors that are attractive, durable, and have low maintenance requirements.
B.
Design Standards. Table 6-6, Non-residential Building Design, establishes design standards for massing and facade composition of all non-residential buildings. The standards apply to all facades that face streets, face through access lanes, or face open and civic spaces, based upon their setback from these spaces. They also apply to any building elevation with a side or rear within 100 feet of a public street (except for the entry feature requirement if it does not face this street). The subsections following the table specify the techniques used to meet the standards for each element in the table.
Figure 6-2 Primary Entrance Features
Primary entrance features activate building frontages and create human-scale points
of emphasis along the building facade. The frequency, rhythm and pattern of entrances
differ depending on the streetscape and frontage type, and determine the degree of
walkability or pedestrian orientation of particular areas.
1.
Primary Entrance Features. Primary public entrances shall be clearly defined on all front facades with at least three of the following elements and be located at intervals specified in Table 6-6, Non-residential Building Design:
a.
A single-story architectural emphasis such as raised parapets or gables, canopies, porticos, overhangs, pediments, or arches.
b.
Transoms and/or display windows that frame and emphasize the entry.
c.
Architectural details such as tile work and moldings, columns, pilasters or other similar material changes.
d.
Integral planters or wing walls associated with a recessed or projecting entry court or plaza that integrates more formal landscape and hardscape designs.
e.
Public art.
f.
For corner buildings, any entrance feature located on the corner may count to both sides, and may be considered located at 25' from each corner for the purpose of the required Primary Entry Feature intervals.
2.
Transparency. Buildings shall have the percentage of openings specified in Table 6-6, Non-residential Building Design, based on the following:
a.
Where expressed as a first story requirement the percentage shall be measured between 2 feet and 8 feet above the street level, or within 10 feet above the first floor elevation if the building is set back more than 20 feet from the street.
b.
Where expressed as an upper story requirement, the percentage shall be measured between the floor level and ceiling of each story.
c.
All first story windows required shall provide direct views to the building's interior or to a lit display area extending a minimum of 3 feet behind the window.
d.
For industrial and civic buildings setback more than 30 feet from the street, clerestory windows may meet the first or upper story window requirements.
Figure 6-3 Transparency.
Transparency requirements eliminate large expanses of blank walls and create physical
and perceptual connections to spaces around buildings. Meeting the requirements for
each story helps reduce the scale of larger buildings.
3.
Massing and Modulation. Larger facades shall be broken into smaller components by one or a combination of the following techniques at intervals specified in Table 6-6, Non-residential Building Design.
a.
Horizontal articulation and differentiation of the base, body and top of the building with material changes, belt courses or trim bands.
(1)
For buildings 3 stories or less, this can be a distinct foundation material to at least 2 feet above grade, the main façade, and an embellished roof structure, such as eaves and fascia for pitched roofs or cornices and parapets for flat roofs.
(2)
For buildings more than 3 stories, the first floor should be clearly differentiated from upper stories to establish the base.
(3)
Any belt course or trim band establishing this break shall use a use a material distinct from the primary material, be 18 to 48 inches wide, and off-set from the wall plane 6 to 24 inches.
Figure 6-4 Horizontal Articulation
Defining buildings with a distinct base, body and top can help reduce the scale of
larger buildings and can create relationships between adjacent buildings with dissimilar
scale.
b.
Vertical articulation and differentiation of structural components or interior breaks of the building with architectural columns or pilasters. Columns, pillars or pilaster shall meet the following:
(1)
Be regularly or symmetrically spaced and divide the elevation into at least 3 different components, but none greater than the intervals specified in Table 6-6, Non-residential Building Design;
(2)
Be at least 18 to 48 inches wide and 6 to 24 inches off-set from the wall plane;
(3)
Use a different arrangement, material or finish to distinguish it from the primary material of the elevation.
Figure 6-5 Vertical Articulation
Defining buildings with a distinct structural bay creates a finer grain of buildings,
both when viewed from a distance and when experienced on the streetscape. This is
particularly important for longer expanses of buildings and can help integrate larger
buildings and lots within a pattern of smaller buildings and lots.
c.
Variations in the wall plane with projections, balconies, cantilevers, step-backs structural focal points such as towers, or other variations from the main mass. Variations shall be associated with the entrance feature, different stories or secondary masses of the building.
d.
Any other blank wall areas in excess of the interval or areas specified in Table 6-6, Non-residential Building Design, shall be broken up by the patterns of windows and doors, ornamental architectural details or changes in materials that are consistent with the architectural style of the building.
4.
Materials. Use building materials with a texture and pattern that create visual interest and signify quality construction and detailing.
a.
The predominant surfaces on building walls shall be one of the primary materials listed in Table 6-7, Non-residential Building Materials.
b.
Synthetic alternates to the materials in Table 6-7 may be approved by the Director if manufacturer specifications and/or precedents for application demonstrate that it will perform equally or better than the principal materials in terms of maintenance, design and aesthetic goals.
c.
No more than 4 materials should be used, including the use of secondary and accent materials.
d.
Material changes and the use of primary and secondary materials from the approved material list shall emphasize different elements of the building, in association with the massing and modulation standards.
(1)
Where material changes are vertical (i.e. different materials stacked one above another), the transition between materials should include a belt course, trim band, sill, cap, frame, roof (if at ceiling height), or similar element to separate the two materials.
(2)
Where material changes are horizontal (i.e. different materials side-by-side) the transition between materials should occur at interior corners or at the trim line, architectural column or pilaster where the change is emphasizing different structural or massing components for a building.
e.
Facade colors shall be low reflectance, subtle, neutral or earth tone colors. The use of high-intensity colors, metallic colors, black or fluorescent colors is limited to accent areas.
5.
4-sided Design. All buildings shall incorporate 4-sided design, so that that no matter what view you have of the building, the design is not interrupted and all parts are perceived as a coordinated part of a unified whole. Specifically:
a.
All sides shall exhibit the same quality, continuity, and durability of design including the same primary and secondary materials, although more important sides can reflect priority in the allocation of these materials.
b.
All sides that are visible from streets, public spaces or active portions of adjacent sites shall have a similar level trim, accent material, details, and ornamentation, although the extent and details may be different to reflect the greater importance of certain areas closest to the public realm or with greater visibility, and parts not exposed to the public may be designed for utility.
C.
Downtown Frontages and Building Design. The building and frontage design standards for the DT district are modified on a block-specific basis according to Table 6-8, Downtown Building & Frontage Design, and the Map in Figure 6-6.
Block-Specific Frontages for DT zoning
Figure 6-6 DT Zoning District Frontage Map
D.
South 4thStreet Overlay District. The South 4 th Street Overlay district is established in Section 4.05.A. to allow a mix of uses within the South 4 th Street Corridor between Bridge Street and Bromley lane, to maintain the residential scale and character of the area, and to introduce small-scale commercial buildings at nodes and gateways. In general, the base zoning district standards shall apply except as modified in Table 6-9 with regard to permitted building types, frontage types and uses.
E.
Alternative Design. For the design standards in this Section 6.05, if the full extent of the design standard cannot be met, the Director may approve an alternative design that equally or better meets the design objectives or enhances another design standard of this section.
