§ 12.5 — Parking Design Standards

FIGURE 12-1 | LINED STRUCTURED PARKING A. Standards. Except where in conflict with the provisions of this chapter, parking facilities shall be designed and built to the standards of SCCC § 18.74.040 through SCCC § 18.74.050. The following standards also apply: 1. Driveways. a. One-way driveways shall not exceed a width of 10 feet; two-way driveways shall not exceed a width of 20 feet. b. Curb cut flares shall collectively not exceed the width of the driveway by more than 20%. c. All driveways shall be perpendicular to the street. d. Driveways shall not affect the slope or direction of the sidewalk. 2. Structured parking a. Where adjacent to any street, structured parking shall be behind a depth of at least 30 feet of occupiable space on the ground floor, except as provided for in §12.4.A.2.c (below). The lining shall be designed per the Standards in Figure 12-1.

b. Fully-subterranean garages may extend to all lot lines. Semi-subterranean garages may extend to building faces, provided that the ground floor is not more than 4 feet above sidewalk grade.See Figure 12-2. FIGURE 12-2 | SUBTERRANEAN PARKING c. Parking structures may be unlined in specific locations. Figure 12-3 regulates "Allowable Garage

Facade Street Exposure", which varies by street and by ground and upper levels. d. Guidelines for efficient and effective parking structures include: i. A 255 ft minimum length allows one bay to slope, rising 10 ft, with the opposite bay having a level floor. The level floor improves visibility and allows for a street-facing facade to be level. ii. A 122 ft minimum width provides for 2-bays with 2-way traffic and perpendicular parking. iii. In the case of a garage in Block B adjacent to the existing office building: 6 levels of parking would make the garage rooftop the same height as the adjacent 7-story office building, potentially creating public rooftop space for both structures (with a connecting bridge). iv. Glass-backed elevators and glass enclosed stairways enhance security. v. Ground floor commercial space in parking garages is encouraged. vi. Garage rooftops can include vegetation and/or solar collectors. 3. Private garages: a. Front-loaded garages are not permitted. On-site parking shall be accessed from alleys or from drives where permitted per Section 5.3.C.
