In the US there is a building code for ramps that says the pitch can be no more than 1:12, or 1 inch elevation for one foot horizontal. That is so that manual chair users can make it up the ramp. Technically it doesn¹t apply for power chairs, but since a public ramp must service both types of chairs, the requirement is what it is.
