Re: Outdoor Stairs on a Slope
You've actually got a lot of different options.
Cut steps into the slop and use a landscape timber as a riser to hold the step/dirt in place. You could just as easily use stone, cement, pavers, or retaining wall blocks for the riser.
The surface of each step can be whatever you want it to be. Leave it grass, use stone, decomposed ag, pavers, cement, stepping stones, etc.
As far as the dimensions of the step, they can pretty much be whatever you want as well. No step should be more than 5 to 6 inches in height, ALL steps should be the same exact height, within 1/8", but the run, or surface of the step can be 12" or 36" or whatever works for the space the best. As an example, your 42" height would equal 7 steps, each step would have a surface run of 2.42 feet.
(42" divided by 6" step rise = 7, 17' run divided by 7 = 2.42 feet for each step.)
Another option would be to form, prep and pour cement steps.
