Regarding the steepness of the steps and how to map them, I'd not only suggest to use "incline" with a percentage (like it is currently done in the area steps proposal) but also permit to enter the height and largeness
Rise and tread .. rise for the near vertical bit .. tread for the horizontal bit you tread (step) on.
(sorry for my English, this is intended as the projected distance of two consecutive risers) of a single step (projection of riser) because these tend to be the same along the whole steps (otherwise people risk falling), and they are easier to survey (no need to calculate). For who reads German, here is an interesting article in wikipedia about this aspect of steps: http://de.wikipedia.org/wiki/Treppensteigung
Lots of interesting things about steps and stairway to do with teh mechanics of the human body and the metal process that we do.
