Ramp slope is the grade of a parking ramp, generally capped near 6.67% where cars park on the ramp, with steeper non-parking ramps permitted and breakover transitions controlled at the crests and valleys. In a parking facility:
- Slope, breakover, and design-vehicle clearance are designed together; each limit exists because a real bumper meets real concrete.
Considerations
- Comfort, drainage, and accessibility all push slope decisions below the code maximum. The right slope is the one the design vehicle never notices.
