Concrete front porch rises 10 inches above ground level. Rather than
having a ramp put in for someone who is having trouble ascending those
10 inches, I am thinking of maybe having 3 or 4 concrete steps
extended out with short risers of 2 1/2 or 3 inches high that would
make it easier to get up to the porch. The tread depth would be 8 or
10 inches. The top step would be 30 or 36 inches wide. Each lower
step would wrap around the two sides, as shown in this top view
(hopefully):


------- porch -------
I___________________________________________I
I I I_______I I I
I I______________ I I
I_____________________ _I


Assuming that the diagram turns out properly when this is posted and
that anyone is able to understand what I am thinking about here, does
this sound feasible and/or practical or would these multiple low
risers present other problems?

Thanks in advance.
