What do I do with this space?

Back yard pictured, Central Oregon.

This used to be grass when I bought the house, but it always felt wasteful to dump water on a plot of grass I never use in the desert. I let it go, but due to some sudden work changes, I’ll be moving out of state and will be putting this house up for rent.

The space has sprinklers. Id like to set up a fairly low maintenance (and low water requirement) solution for the renters. Any ideas for a good ground cover that would tolerate Central Oregon well?

Thank you!
