Stop in for a cup of coffee

The laser level showed me what I wanted to know. SW slope from the house is now 3” higher from the center point to the property edge at 10’...and the down slope side from the center point is also 3” down at 10’ from there.

After that, it is 6” down at 10’ and continues at that slope for another 40’ to the street. The property line is raised 10” from the other side which has an opposite slope, so nothing from that side intrudes.

Nailed it!
