It does not sound all that steep, 1' drop in 10'. What exactly are you trying to accomplish? Establishing a lawn? More info please.

When doing detention basins or cuts where I will have water runoff coming down on my slopes, I will create slight diversion ditches. For example, I'll cut a small ditch in along the top of the slope of a detention basin and then I'll run it all the way to the corner of the basin and then I'll curve it in and I'll rip rap the corner down to the bottom to prevent any erosion.

More info is needed, is this slope covered or bare dirt, etc.

Does this site work have a NPDES permit, it sounds like it is large enough to require one.

You need a low ground pressure embankment grade inverter with a 5-way blade and gps traveler to do the grading you're describing. Use a high volume hydraulic driven sod blower to get it stabilized quickly. Your local Cat dealer can probably rent both to you.

I've met a few Engineers that think they know how to do this.

I have seen this method used before, just amazing how they do it!
