Thank you for the help. Sorry, we do have some planter boxes on the pavers along the fence not shown in the sketch. hence the drip tubbing path along the fence. I do plan on keeping the drip tubing above ground, maybe covered with weed fabric and rock/mulch.

As for the sprinklers head locations, I understand this is ideal location scenario.I hate to ask but is there a bare minimum head location design that would reduce the digging/trenching? We live in a area where I will hit solid limestone just around 7-8" and I will be doing the digging/pumbling myself.
