Question
I'm attempting to create flared steps made out of sod on a short slop in my landscape. {Sort of "Masa Picchue" like}
There will be a Boxwood Hedge on either side .I live in Atlanta GA. [Zone 8]
Could you please advise how to do this? The dimensions are:
run-21'
rise-30"
1st step-6'wide
last step-10'wide
I would very much appreciate the help.
Thank you.
Betsy

Hello, Betsy ~
Here are a few picture links of what I think you are trying to accomplish:

Based on the dimensions you provided, there will be a total of 4 steps, with a rise or 8-1/8" per tread, assuming the first 6' step down is counted in.

So, it is step down 8-1/8" to a 6' wide tread, next step down to the 5' wide tread ,then to the 10' wide tread, then a step at the end, also 8-1/8" down.  (A total of 4 vertical transistions, & 3 lateral ones). like so:
  
start:
     ------:
            -----:
                  ----------:
                             end

You'll have to edge the sod steps with something, like railroad ties, concrete steps, or metal edging (see pictures).  I find that just "easing" the sod down between transitions makes for an akward step, even though it may be easier to mow.  Tripping down a hill in the dim evening light is no fun!

Edging with boxwood sounds nice - like miniature handrails.

Here is a website to help you pick the right lawn type for Atalanta/zone 8:

Good luck & sorry for so many links! ~M
