23.408.070 Development Standards.
Green Pathway projects shall comply with the applicable development standards in Section 23.204.130 (C-DMU Downtown Mixed-Use District) and the following additional requirements.
A. Building Setbacks Within View Corridors. To minimize interference with significant views, buildings that are 75 feet in height or less that are located on a corner lot at any intersection with University Avenue, Center Street, or Shattuck Avenue must include upper story setbacks as follows: any portion of a building between 45 feet and 75 feet must be set back from property lines abutting the street by at least one foot for every one foot by which the height exceeds 45 feet.
B. Street Wall Facade. Notwithstanding the Downtown Design Guidelines, the street wall facade shall be architecturally modulated by volumes that are 50 feet in width or less.
1. Smaller modulations may be incorporated within larger volumes.
2. Volumes along the street wall must be defined by structural bays and/or substantial reveals or offsets in the wall plane, and by changes in the rhythmic pattern of one or more of the following features:
(a) Window openings, oriel windows, or balconies.
(b) Awnings, canopies, or entrances.
(c) Arcades, columns, or pilasters.
(d) Materials and color.
(e) Other architectural features.
C. Shadow Analysis. A shadow analysis is required for buildings with heights between 60 and 75 feet. Applications shall include diagrams showing:
1. The extent of shading on public sidewalks and open spaces by a building 60 feet in height that complies with all applicable setback requirements on an area within a radius of 75 feet of the closest building wall that would be cast on March 21, June 21, December 21, and September 21 at the following times of day:
(a) Two hours after sunrise;
(b) 12 p.m. noon; and
(c) Two hours before sunset.
2. Features incorporated into the building design, including, but not limited to, additional upper floor setbacks that will reduce the extent of shadowing of the proposed building to no more than 75 percent of the shadowing projected in previous Paragraph (1).
D. Height Restrictions. Consistent with the height standards of Measure R (adopted November 2, 2010), Section 4.B., as required by Section 3, Paragraph 12, Green Pathway Buildings of exceptional height are restricted as follows:
1. Two mixed-use buildings and one hotel/conference center in the Core, no more than 180 feet in height.
2. Two buildings, up to 120 feet in height in the Core or Outer Core.
E. Mitigation Measures. To ensure that potential environmental impacts are mitigated to less than significant levels, projects under this chapter are subject to applicable measures identified in the adopted Mitigation Monitoring Program of the Downtown Area Plan Final EIR. (Ord. 7787-NS § 2 (Exh. A), 2021)
