- Building Articulation Implementation.
-
- Street-facing Facades shall be modulated along the street at least every forty feet. Building modulations may be achieved in any one of the following ways. (R)
-
-
- A step back or forward in the building wall of at least four feet. See Figure 17C.111.325-B.
-
-
- For facades no more than two stories high, a bay window or cantilevered bump-out at least four feet (4’) wide and two feet (2’) deep on the ground floor.
-
-
- A cantilevered bump-out at least four feet (4’) wide and two feet (2’) deep that extends vertically the entire height of the facade.
-
-
- A covered porch at least ten feet (10’) wide and six feet (6’) deep.
-
- The scale of buildings be moderated to create a human scale streetscape by including vertical and horizontal delineation as expressed by bays, belt lines, doors, or windows. (P)
-
- In addition to the requirement of subsection (C)(1), street-facing Facades thirty feet (30’) or longer shall include at least one of the design features listed below, or a similar treatment, every thirty feet (30’). The modulation implemented to meet subsection (C)(1) may be counted in meeting this requirement. (P)
-
-
- Design Features.
-
-
-
- Varied building heights.
-
-
-
- Use of different materials.

- Consideration for Historic Features.
Development should reduce the potential impact of new housing on established and historic neighborhoods by incorporating elements and forms from nearby buildings. This may include reference to architectural details, building massing, proportionality, and use of high-quality materials such as wood, brick, and stone. (C)
