This is all good advice regarding how to handle a 6-8″ grade change in a residential patio. I was considering the patio at the top to be the “step” even though according to Mark’s definition, it isn’t really a tread, it’s the patio. I agree with Mark and others, therefore, that it would be very easy for someone to back into that single 6-8″ riser and trip. I can put a contrasting tread on top and narrow the travel space with planting to telegraph the change. I may also see if I can get the client to go with a ramped transition rather than a step. You don’t usually see that in a residential patio though but it might make it easier to wheel in the kegs. Thank you everyone.
