Park District Planned Development Overlay | Exhibit A.2 – Park District Design Standards Page 11 <br />Exhibit A.2_Park District PDO_Design Standards_24-0703 <br />B. Ground-level residential building frontage standards. <br />1. Applicability. These standards apply to spaces within residential buildings including <br />dwelling units adjacent to sidewalks, plazas, or publicly-accessible paths and park <br />space. <br />2. Purpose. <br />a. To integrate human-scaled design treatments to enhance the safety and character of <br />streetscapes while respecting the privacy and livability of adjacent residential units. <br />Human-scaled design treatments provide for a combination of vertical and horizontal <br />features that articulate the ground levels and/or first two levels of a structure and <br />provide an emphasis on entrances and recognizable references to the human <br />activities within the adjacent space through window design or other characteristics. <br />b. To provide an effective and attractive transition between the public and private <br />realm. <br />c. To avoid building designs that deprive ground level dwelling units of reasonable solar <br />access due to overhanging building volumes or structures. <br />3. Standards. All residential building frontages must utilize at least two of the measures <br />listed under subsections (a) and (b) and demonstrate how the ground level frontage <br />design meets the purpose of the standards. <br />a. Ground level frontage. <br />i. Setback. Provide a five feet minimum landscaped setback from the sidewalk and <br />the exterior wall of any unit. <br />ii. Elevation. Where the exterior wall of a dwelling unit is within ten feet of a <br />sidewalk, raise the ground level at least two feet above the level of the sidewalk <br />to help to improve privacy and enhance their relationship to the street. <br />iii. Planters. Provide raised landscaping planters at least two feet wide and 16 <br />inches tall in the transitional area between the dwelling unit and the sidewalk <br />(see Figure 3.B.1 below for examples). <br />b. Measures specific to dwelling units with direct ground-level access. <br />i. Provide a physical “threshold” feature such as a retaining wall, rockery, stair, <br />gate, railing, landscaping, or a combination of such elements on private property <br />that defines and bridges the boundary between the sidewalk and the private <br />entry. Thresholds may screen but not completely obstruct views to and from the <br />sidewalk. Refer to Chapter 19.40 EMC for fence height standards. <br />ii. Provide an outdoor space at least four feet deep and six feet wide (24 square <br />feet minimum area) between the sidewalk and the dwelling unit entry such as a <br />porch, patio, deck, or stoop (for stoops, refer to diversity requirements in Section <br />5.1). Where feasible, this space must be at the same level as the interior of the <br />unit.
