We have not added automatic sprinkler systems yet but will do so at a later date.
Rob,
Nice stones and rock work! It will look great with the grass. But..
A golden rule for landscaping/hardscaping. Irrigation system first (at least main supply lines), hardscape second, landscape third. I know the terracing is high on your agenda but be careful not to box yourself in for the "later" irrigation system. Like if you need a water line installed below that rock wall.
When we built we knew we would not get to landscaping for some time but when I ran the water mains I branched out and placed hose bib risers around the homesite (where we thought we may irrigate). Before the hose bib I placed a "T" and cap for future irrigation valves. While the trenches were open and available I ran irrigation wires too. We did not have a planting plan and I'm now having to be a bit creative on planting due to underestimation how many stations were needed where, (and I have too many wires at some spots) but we at least have several options available versus tearing up stuff already built.
Another thing I did while the ground was torn up in construction phase was to run a couple of "future-proof" conduits into the building, in our case the garage where the irrigation controllers are located, and dead ended them out in an accessible place. These are for running lines you don't think of now but are needed or wanted later. One of these has already saved me when we decided to irrigate a section we never thought we would and I needed to add another five irrigation stations in two outlying valve boxes. The added extra conduits were in place so I never had to trench up to the building, cross driveway, cross house and hydrant water main,etc.
Not having a fully baked planting plan in the first place taught me something the hard way is when you run your main irrigation supply piping place a "T", short straight, and cap every hundred feet more or less. This gives you an easy "add-on" tap-in opportunity; much easier than trying to "T" into an existing single, unbroken, buried, irrigation main.
I build my valve manifolds with a "T" and cap past the last valve for easy add on too.
Now you may be way ahead of me on the above suggestions and have all this stuff worked out...if not hope these things can save you some frustration "later". So if you haven't yet run irrigation wiring to your controller location, when you do, add some extra wires and maybe some future proof conduits so you only have to dig up that area once.
oh yeah, the platinum underground utility rule, keep track of your work. On our job sites we use a digital theodolite and record survey coordinates of our as-builts but I posted my home-owner method

The red-tail hawk photo was great. In the Oregon outback we watched from our dining table window a mother hawk teach her two youngus to fly. Alas, no photos. Thanks for sharing.
