23.48.740

Street-level development standards in Section 23.48.040 apply to all streets in the SM-UP zones. In addition, the following requirements apply: A. Street-level facade requirements; setbacks from street lot lines. Street-facing facades of a structure shall be built to the lot line except as follows: 1. The street-facing facades of structures abutting Class 1 Pedestrian Streets, as shown on Map A for 23.48.740, shall be built to the street lot line for a minimum of 70 percent of the facade length, provided that the street frontage of any required outdoor amenity area, other required open space, or usable open space provided in accordance with subsections 23.48.740.B and 23.48.740.C is excluded from the total amount of frontage required to be built to the street lot line. 2. If a building in the Uptown Regional Center faces both a Class 1 Pedestrian Street and a Class 2 Pedestrian Street a new structure is only required to provide a primary building entrance on the Class 1 Pedestrian Street.

For streets designated as Class II and Class III Pedestrian Streets and Green Streets as shown on Map A for 23.48.740, and as specified in subsection 23.48.740.B.1, the street-facing facade of a structure may be set back up to 12 feet from the street lot line subject to the following (as shown on Exhibit B for 23.48.740 ): a. The setback area shall be landscaped according to the provisions of subsection 23.48.055.A.3; b. Additional setbacks are permitted for up to 30 percent of the length of portions of the street-facing facade that are set back from the street lot line, provided that the additional setback is located 20 feet or more from any street corner; and c. Any required outdoor amenity area, other required open space, or usable open space provided in accordance with subsection 23.48.740.B is not considered part of the setback area and may extend beyond the limit on setbacks from the street lot line that would otherwise apply under subsection 23.48.740.B. Exhibit B for 23.48.740 Street-level setbacks B. Required usable open space in the SM-UP 65, SM-UP 85, and SM-UP 160 zones 1. In the SM-UP 65, SM-UP 85, and SM-UP 160 zones, on lots exceeding 30,000 square feet in area, proposed development shall provide usable open space as follows: a. The minimum amount of required usable open space shall be equal to 15 percent of the lot area and shall generally be accessible at street level, with variations in elevation allowed to accommodate changes in topography; b. The average horizontal dimension for any area qualifying as required usable open space is 20 feet, and the minimum horizontal dimension is 10 feet, except that there is no minimum horizontal dimension for additional pedestrian area abutting a sidewalk that is provided according to subsection 23.48.740.B.1.c; c. A minimum of 45 percent of the required usable open space shall be exterior space open to the sky and shall abut a street along at least one street frontage and provide both visual and physical access from the street lot line to pedestrians, including persons with disabilities; d. Up to a maximum of 20 percent of the required usable open space may be covered, if the open space abuts a street lot line and is open and accessible to pedestrians along the sidewalk; e. Up to a maximum of 35 percent of the required usable open space may be provided as enclosed space, such as atrium, a shopping atrium, wintergarden, or covered portion of a through-block pedestrian connection, if the enclosed open space meets all of the following requirements: 1) Direct access is provided to pedestrians, including persons with disabilities, from the street, or from an outdoor, usable open space abutting the street; 2) The space is provided as one continuous area that is a minimum of 2,000 square feet in size. Space, such as lobby area, that is used solely to provide access between the structure's principal street entrance and elevators, does not qualify as required usable open space; 3) The minimum floor-to-ceiling height is 15 feet; 4) The space is accessible to the public during normal business hours; and f. Up to a maximum of ten percent of the required usable open space may be provided as an area abutting a sidewalk that extends the pedestrian area onto the lot or accommodates landscaping or extensions of right-of-way green factor treatment. Minor changes between the sidewalk elevation and the elevation of the abutting sidewalk area are permitted to accommodate changes in topography, or to provide for features such as ramps that improve access for persons with disabilities. 2. Usable open space provided under this subsection 23.48.740.B is eligible to qualify as either amenity area for residential uses under Section 23.48.045 or open space required for office use under Section 23.48.750 , or both, provided the applicable standards of Sections 23.48.045 and 23.48.750 are met. C. Through-block pedestrian connections for large lot developments 1. A through-block pedestrian connection meeting the standards of subsection 23.48.740.C.2 is required in the SM-UP 65, SM-UP 85, and SM-UP 160 zones for development described as follows: a. The development is located on a lot having a minimum lot area of 40,000 square feet; and b. The lot abuts the two north/south avenues for a minimum linear distance of 120 feet along each avenue. 2. The required through-block pedestrian connection shall meet the following development standards: a. A continuous pedestrian passageway shall extend across the lot to connect either two streets or avenues whichever the development abuts. If the development site abuts two avenues and two streets, the passageway shall connect the rights of way that have the greater length. The alignment of the passageway and the point at which it intersects each avenue shall be no closer than 100 feet to a street intersection, and the connection of the passageway to abutting sidewalks shall be accessible at the grade level of the sidewalk. b. The required pedestrian connection shall have an average width of 25 feet and a minimum width of 15 feet. Any segment of the pedestrian passage that is covered by an overhead covering from side to side shall have a minimum width of 20 feet. c. The pedestrian passageway shall be open to the sky, except that up to 35 percent of the length of the passageway may be covered and enclosed, provided the minimum height of covered portions is 13 feet. Unenclosed area of the passageway may be counted as required open space; and d. If the passageway crosses an alley, the alley right-of-way shall be improved to ensure pedestrian safety and to reinforce the relationship between portions of the passageway on either side of the alley. 3. The Director may allow modifications or waiver from the standards for though-block pedestrian connections as a Type I decision, if the Director determines that alternative designs will better serve the development by enhancing pedestrian comfort and promoting greater use of the connection.
