Is a 1/8 inch per ft. slope (away from the house) sufficient for a patio?
I have excavated, graded, compacted, added gravel in 2-inch stages, and compacted again. I've been doing this with a 1/4 inch per ft. slope away from the house. Unfortunately, I now discover that using this degree of slope will not allow me to connect properly with the remainder of my lawn without running into problems with the stoop at the back of my house (a long story). So I 'm thinking of re-grading the last segment of gravel to make the slope a 1/8 inch grade. I'm wondering if this is sufficient for a patio that is northern exposure and often gets a good bit of snow (Denver, CO). I'm also wondering if the 1/8th inch drop will hold up if I compact it thoroughly, given that the early layers were compacted with a 1/4 inch grade. Any info or advice will be much appreciated.
