My front yard has a nine ft drop from the front porch to the side walk. I don't know wha the slope is, but I do know it is very difficult to mow.  The side of the house is even more difficult to mow. I want to have the yard landscaped so that the slope is safe to mow, preferrably with a riding mower.  I know the drop from the front porch to the side walk is 9 feet. My driveway is sloped so one landscaper is suggesting to match the slope of the yard to the drive way, but I don't know if that will be a safe slope to mow.  I have talked with other landscapers who are suggesting that I put in two three foot retaining walls, but the projected costs are $25k+.  Is there a group that I can work with to determine if it is possible to put a manageable slope in this yard so that I don't have to invest $25k and still achieve the goal of reducing the level of mowing difficulty?
Thank you.
