A. Parking structure dimensions and design shall be subject to review and approval by the Transportation Manager.

B. Ground-floor windows/wall openings. All above-grade parking structures shall provide ground-floor windows or wall openings along the street frontages. Blank walls are prohibited. Any wall facing the street shall contain windows, doors or display areas equal to at least 20% of the ground floor wall area facing the street excluding those portions of the face(s) devoted to driveway entrances and exits, stairwells, elevators and centralized payment booths. Required windows shall have a sill no more than 4' above grade. Where the interior floor level prohibits such placement, the sill may be raised to allow it to be no more than 2' above finished floor wall up to a maximum sill height of 6' above grade. These openings shall be glazed or grated.

C. Entrance/Exit Design. Adequate vision clearance shall be provided so that motorists leaving a parking structure have a clear view of the sidewalk on either side of the exit, and so that approaching pedestrians have a clear view of any approaching vehicle. Parking structure entrances and exits shall be designed to achieve travel speeds not to exceed 5 miles per hour, and shall require a vehicle stop directly prior to crossing the street sidewalk. Entrance and exit areas shall be designed so that vehicles approaching or leaving the parking structure can queue to enter/exit the traffic stream without blocking the sidewalk.

D. Parking Structure Internal Design and Pedestrian Circulation. Parking structure internal circulation design shall include provisions for the safe and convenient circulation of pedestrians. Design speed shall not exceed 10 miles per hour, and traffic control measures shall be provided at any location where vehicle circulation crosses a pedestrian walk way. (Ord. M-3643, 2004)
