We will have 3000 feet of 24" and 5000 feet of 36". The pipe size at the road crossing will be 36" and the depth will be almost 9' on the north side and almost 8' on the south side. Stone owns both sides of the crossing. It will be 750 feet east of the driveway or 3000 feet west of M54.

On your map, can you provide sizes of tile that you are proposing. I will need that to size the size of pipe at crossing. What depth will you be at? I can get a list of the property owners off Beason, but will need to send you the permit for signatures of each property owner.
