how about using the two scaffolding planks idea but having the left side (as you look at it in the photo) hinged so that you can lift the planks/ramp out of the way. you could lock it up with a padlock/disclock etc to avoid it falling on anyone. the angle it would lie at when flat would mean that the high corner would move away from the pavement so wouldn't cause an obstruction. but the other end would need to have clearance obviously - would that affect your neighbour on that side - is that the one you share the steps with?
