Site Balancing Feature and Yield Factors

I assume by balancing, this is also referring to "flattening" the layout?

For example when we do initial site cuts on an existing block that formely had a building or two, it'd have a number of preexisting site cuts, would be nice if we could flatten to a more common surface level the estimated site and backfill into the cuts.

The other method I can thick of, assuming the site has a fairly consistent surface plane is to use a slope tool to level out.
