I have a 5 acre surface which includes a 2 acre parking lot. I want to lower only the parking lot area to bottom of subgrade level and then grade back to surface at 10:1 for mass grading purposes. Anyone have any good ways to do this? Thanks
I would create a Featureline of the parking lot area. Raise the featureline to the EG surface. Then Lower by Subgrade depth and daylight to EG with the desired slope with the grading tools. Finally add the Featureline and grading to a surface to calculate the volumes required.

Thanks. After adding a boundary and lowering the surface I beleive you will then have to paste it back into your orginal surface
