The lot if you look at the sat photo is easy to define pretty much... Drive way entrance to the Cul De Sac.. then up the arroyo from that point to the top which about 200 feet lateral above the house.. The other line is from the drive entrance to past the neighbors turn around (runs right against it) on your right.. Kinda of a trapezoid?
You can pick out the drainage areas .... We would traverse most the slopes until we hit a drainage... Then up and down those .. section it out.. Repeat...
