TABLE 155.3703.F.5: MINIMUM FENESTRATION/TRANSPARENCY WIDTH
Fenestration/Transparency Standard1	Commercial /Mixed-Use Development	Residential Development
Ground-level building facade width occupied by transparent window or door openings, minimum (% of minimum building facade width required to be within build-to zone by Section 155.3703.D.4, Yard   Setbacks and Building Facade Placement)	50 2	30
NOTES: 1. This standards also apply to any portion of a ground-level facade facing a courtyard or patio formed in accordance with Section 155.3703.F.3, Formation of Courtyard or Patios. 2. To count toward this transparency requirement, a window or door opening must have a maximum sill height of 2 feet above grade and a minimum head height of 6 feet, 8 includes above grade. (See Figure 155.3703.F.4: Building facade transparency.)

 

         b.   Fenestration Standards

      Any transparent window and door openings occupying a ground-level street-facing building facade shall comply with the following standards:

            i.   The opening shall be filled with glazing that has a minimum visible light transmittance of 75 percent and a maximum reflectance of 15 percent.

            ii.   The opening shall be designed to allow view of an interior space at least five feet deep (e.g., transparent openings may include traditional storefront display windows, but not merely glass display cases). The view into a commercial use shall not be permanently obstructed by screens, shades, shutter, or opaque films applied to the glazing.

      6.   Parking Deck or Garage Design

         A parking deck or garage shall be designed in accordance with Parking Deck or Garage Design Standards in Section 155.5605 of Parts 6 (Design Standards) of Article 5: Development Standards. In addition, the following design standards shall apply:

         a.   Vehicular entranceways and exits shall be provided from a side street where feasible.

         b.   Ground Level Standards. Facades which face a street shall provide habitable space along the ground level facade in accordance with the following standards:

            i.   A parking deck or garage with occupied space above a ground-level parking area shall provide occupied space at least 20 feet deep along the structure's ground-level street-facing facade.

            ii.   A parking deck or garage with only one street-facing facade shall provide at least 75% of the width of the street-facing facade with habitable space. Such habitable space shall extend at least 20 feet into the structure.

            iii.   A parking deck or garage with more than one street-facing facade shall provide at least 75% of the width of one of the street-facing facades with habitable space. Such habitable space shall extend at least 20 feet into the structure. Except that facades facing East Atlantic Boulevard or Pompano Beach Boulevard shall always provide the 75% habitable space.

      7.   Architectural Style Standards

         a.   General

      All new development within the Atlantic Boulevard Overlay district shall reflect a Florida Maritime vernacular style that includes elements derived from certain historic styles and design features prevalent in South Florida and shall comply with the design standards in this subsection applicable to one of the following three architectural substyles of the Florida Maritime style: Tropical Old Florida; Tropical Contemporary; or Nautical Moderne. The applicant for approval of new development may choose which architectural substyle to use for the development, but may not mix usage of standards for different substyles.

         b.   Street-Facing Facade Standards Also Applicable to Courtyards and Patios

      Architectural style standards applicable to street-facing building facades shall also apply to building facades that face a courtyard or patio formed in accordance with Section 155.3703.F.3, Formation of Courtyard or Patios.

         c.   General Descriptions of Allowed Architectural Substyles

      Below are general descriptions and photographic examples for each of the three architectural substyles allowed in the Atlantic Boulevard Overlay district. The descriptions and photos are intended to serve as general guides to the architectural substyles allowed in the district. The design standards in subsections d through 155.3703.F.7.a below govern how each substyle is to be achieved.

 

i.   Tropical Old Florida Architectural Substyle

(A)   Description

Development of the Tropical Old Florida architectural substyle was largely in response to climate factors. It therefore includes many elements that relate to protection from the sun and rain, both within the building and around it. The Tropical Old Florida substyle consists mostly of low-rise construction and is characterized by simple, rectilinear building configurations. Other elements of this substyle include such features as metal or flat-tiled roofs, Bahamian shutters, arcades with arched openings, extended overhangs, verandahs, various light filtering devices on windows (e.g., lattices, grilles, louvers), multi-paneled doors and windows, etc. Materials traditionally include concrete block with a smooth stucco finish, and often wood siding—with wood doors and window frames, and cast stone for detailing. Colors are usually off-white or light pastels.

ii.   Tropical Contemporary Architectural Substyle

(A)   Description

While a broad category, the Tropical Contemporary architectural substyle is a more modern variation of Florida vernacular architecture, blending some tropical motifs such as climate-sensitive roof forms with contemporary design elements such as vertical orientation, sparsely used ornamentation, vertically-oriented metal casement windows, and materials such as concrete and steel structural frames, and standing seam metal roofs. Vertical orientation is established in a variety of ways, such as towers or other projections, tall, narrow windows, exposed vertical beams (real or apparent), and use of colors. The Tropical Contemporary substyle is generally found in mid- to high-rise construction, often residential in use.

(B)   Photographic Examples

 

 

iii.   Nautical Moderne Architectural Substyle

(A)   Description

The Nautical Moderne architectural substyle is a combination of International, Art Deco, Miami Modern (MiMo), and other modern styles, infused with elements that make projects reminiscent of ocean liner cruise ships. Used mostly in mid- and high-rise construction, this substyle emphasizes a horizontal orientation resembling the decks of a ship, metal detailing (e.g., balcony rails.), rounded exterior walls and details, and continuous balconies on substantial portions of upper floors. The building facade is typically characterized by extensive use of glass. Additionally, nautical-themed details on both the building and the site, such as wooden bollards resembling posts found at a dock and connected by rope, flag poles, and similar elements can be used to help achieve cohesion in the overall theme.

         d.   Building Facade Articulation

            i.   General

         Street-facing building facades may be articulated through incorporation of one or more of the design elements described in this subsection and in accordance with the standards set forth below in Table 155.3703.F.7.d for the proposed architectural style and the specific articulation element(s) used. These standards apply in addition to the building facade offset standards generally applicable to commercial and mixed-use developments (See Section 155.5602.C.4, Facade Articulation.).
